CCC Net Zero Report - The United Kingdom Anaerobic Digestion Industry Re...




ADBA Press Release:

United Kingdom AD Industry Responds to CCC Net Zero Report

Responding to the publication of the Committee on Climate Change's (CCC's) new report calling for the UK to set a net-zero target for 2050, Charlotte Morton, Chief Executive of the Anaerobic Digestion & Bioresources Association, said:

"The UK's anaerobic digestion (AD) industry fully supports the Committee on Climate Change's call for net zero emissions by 2050, which is a vital target to ensure we avoid the worst effects of climate change. 

"By converting organic wastes and crops into renewable heat and power, clean transport fuel, and soil-restoring natural fertiliser, AD has already reduced the UK's greenhouse gas emissions by 1% and has the potential to reduce them by as much as 5% if the industry meets its full potential. Crucially, AD reduces emissions from hard-to-decarbonise sectors such as heat, transport, and agriculture, as well as from the power sector and from waste. 

"As a technology-ready solution that can tackle climate change right across the economy, it's vital that government recognises and rewards the many benefits of AD so it can make the maximum contribution to decarbonisation at speed and scale. 

"We therefore also support the CCC's call for a new regulatory and support framework for low-carbon heating (where biomethane from AD can make an important contribution) to address the current million-pound funding gap."

Reactions Across the Web to the CCC Net Zero Report

Image shows thumbnail for the CCC Net Zero Report ADBA response.
There has been a welcome response from numerous groups to the CCC’s report with the top line call for the immediate enshrining into law of a national net zero by 2050 target to be put forward by the government.
However, the report does also note that some home nations are currently better equipped to deliver more rapid decarbonisation than others. Scotland, for example, is encouraged by the CCC to target net-zero emissions by 2045 – due to a greater potential to depollute its economy compared to the rest of the UK – whereas Wales should target a 95% reduction in emissions by 2050 (from the same 1990 baseline).

Call for CfD Scheme for Small Scale Anaerobic Digestion in the UK



Renewable Energy CfD Scheme Call

Small-Scale UK Renewable Energy CfD Scheme Called for.

On the day that the UK didn’t leave Europe, trade association ADBA called for a Contracts for Difference (CfD) scheme for Small-scale Renewable Energy including biogas.


ADBA also calls for AD not to be excluded from future CfD auctions.


The trade body for the UK’s anaerobic digestion industry calls on the government to introduce a bespoke low-carbon Contracts for Difference  scheme to support small-scale renewable technologies.


ADBA did this on 29 March 2019, the day the Feed-In Tariff subsidy was ended by the UK government.


AD plants generate renewable electricity, heat, and natural fertilizer by treating organic wastes and energy crops. They also offer a range of other benefits including greenhouse gas mitigation from avoided waste emissions, income diversification for farmers, and energy and fertilizer supply security.


The UK’s AD industry currently has capacity to power 1.2 million households, offering flexible, baseload power, but has the potential to generate far more, with the right support.


“Beyond this levelling of the playing field with the big generators, they are calling on government to develop a bespoke, small-scale, low-carbon CfD auction mechanism to encourage competition in the small-scale sector and recognize the additionality that AD can provide in the form of greenhouse gas mitigation, agricultural diversification, and energy and food security.

Biogas Plant in Balcony, Indian Man Slashes LPG Bill by Half! and More!

Recently we wrote a report about the state of anaerobic digestion plant and biogas development in India. We noted that at national government level there was very little indication of any top-level awareness of the great potential for the betterment in India, available from biogas technology.

We said that this was disappointing because once India led in biogas. The was a growing number of small rural biogas plants and its production was having many spin-off advantages.

The same is not true in some parts of India where a number of people are developing their own biogas plant systems and helping those around them to join in with the advantages of anaerobic digestion. This, we think you will agree is amply demonstrated in the following article extracts:

1 - Jharkhand Man Installs Biogas Plant in Balcony, Slashes LPG Bill by Half!

Able to serve a family for four years, the entire portable structure cost him less than Rs 10,000 and took a few hours to assemble. No wonder he is the talk of his neighbourhood now!

Almost 160 years ago, the first successful biogas generation plant was established in Mumbai, India. Since then, approximately five million biogas plants cater to domestic needs like water heating and cooking.

Contrary to this, various countries, especially Germany, have been efficiently harnessing its benefits in other sectors.

“Having been the forerunners, we should have led ahead of all in ushering the biogas revolution, not the European countries like Germany, that have become forerunners of biogas utilisation, both in domestic and public spheres,” said a senior corporate executive, while speaking to The Better India.

Based in Jamshedpur, this executive, Gaurav Anand, has led the movement by becoming the first man in the steel city to build a biogas plant small enough to fit into his apartment’s balcony!

Not only has it slashed his monthly expenditure on LPG, but has also rewarded him with rich slurry compost that makes his garden bloom.  via Jharkha

2 - Patna Girl Builds Biogas Plants, Provides Electricity to Poor Farmers!

City born and bred she may be, yet Akansha Singh was aware of the economic and social inequalities that exist within India. But it wasn’t until she got to the ground and observed first-hand did she realise the scale of the issue.

After completing her Masters in Social Entrepreneurship from the Tata Institute of Social Sciences (TISS) in 2014, Akansha had set out to Jhabua district in Madhya Pradesh as part of an internship.

She was 24 at the time.

“That was a devastating eye-opener for me. The two weeks that I was there, I observed no households had toilets neither did they have any proper power supply. Which meant, the women had to cook food before nightfall as their farmer husbands finished their farming activities by that time. One thing that had particularly affected me was that these families consumed their meals cold because they had to finish preparing dinner while there was still natural light,” says Akansha to The Better India.
During this period, she noticed many social and environmental issues in the region. The women were still cooking using cow dung cakes, and the entire family was inhaling hazardous smoke regularly.

Finally, after months of convincing and explaining to them the many benefits of the project, the villagers yielded, and Akansha began looking for land to build the plant.

“Fortunately, a person from another community volunteered and donated a patch of land for the project. It is remarkable as caste system is much prevalent in the region, but this kind individual wanted the underprivileged community to lead better and empowered lives. From there, our journey started,” she says.

Today, they have two biogas plants in Samastipur; one with 2-hour bioelectricity capacity while the other supplies power for four hours.

Swayambhu received its initial funding from DBS Bank, Singapore. Her project was also aided partly by the beneficiaries and mostly by both government and non-government agencies.

“There has been a visible change in these areas. After seeing how electricity has brightened up their lives, the beneficiaries have become truly committed to the cause and pay charges without fail. Also, ever since they have ditched chemical pesticides and fertilisers for the organic manure from the plant, they have been saving a considerable amount of money as well as observed better yield. Our solution has impacted in multiple folds,” 
Akansha adds.

In addition to community biogas plants, they have also worked on individual plants for bioelectricity, including one in collaboration with students of IIT Patna.

A Biogas Startup By An IIT-Bombay Alumnus Aims To Fight Air Pollution And Manage Waste


New Delhi: 34-year-old Priyadarshan Sahasrabuddhe, a Pune based engineer is trying to provide a solution for two of the biggest environmental problems facing India – air pollution and burgeoning waste pile ups. 

The IIT-Bombay alumnus has launched a technology to produce cooking gas fuel by repurposing the organic-waste produced in the kitchen and at the same time reducing the dependence on fossil fuels. In 2017 he created ‘Vaayu’, a biofuel plant that can be easily installed at homes to convert carbohydrates from organic waste into methane gas which can be used for cooking and heating purposes.

“I was working at my parent’s firm about two years ago and I noticed that every day after lunch, a lot of leftover food used to end up in the garbage bins. Watching all that food go waste, I thought of trying composting to manage that waste. But it was not enough. On researching more, I came to know about biofuels. I found that not only will it help in managing organic waste, it will also help in reducing our dependence on non-renewable sources like LPG,” 
said Mr. Sahasrabuddhe.

“Waste segregation is the key here. Initially, when I started advocating for green living, I used to go to each house in my locality every morning to ask them to segregate their waste. There were days when I myself used to pick organic waste from the nearby garbage dumps. But gradually when my neighbours started to understand ‘Vaayu’, they started segregating and I get almost 8- 10 kgs of organic waste at my doorstep every day,” 
said the engineer turned innovator.

After a long period of testing of the device at his home and reducing his dependence on LPG to a significant extent, Mr. Sahasrabuddhe pushed others in his family, neighbours, and friends to start using this innovation. Till date his startup has done 135 installations in Pune, Sangli, Aurangabad, Umarkhed (District Yavatmal), Palghar, Nashik and Hyderabad. These installations together are managing up to two tons of food waste per day and saving about 900 LPG cylinders worth fuel per year.

How Does ‘Vaayu’ Work?

‘Vaayu’ is a domestic bio-gas machine which can be installed in the house, in the gallery, on the terrace or in the garden. The apparatus is fuelled by the waste generated in the kitchen which gets broken down by bacterial action known as Anaerobic Bacterial Digestion. Through this process, the carbon dioxide captured inside the organic waste during photosynthesis is divided into methane gas and liquid. The gas is stored in the balloon kind of a structure called the cylinder which is connected to the stovepipe. The cooking experience is exactly the same as that of a regular LPG or piped CNG (Compressed Natural Gas). The slurry generated in this process is high on nutrients and can be utilised as manure for the plants in the house.

The regular size ‘Vaayu’ has a container of two kg capacity in which the organic waste is put. A single two kg container, ‘Vaayu’ produces 200 litres of biogas within 24 hours which is 40 minutes of cooking gas per day saving up to three LPG cylinders per year. The capacity of the device can be increased by adding the containers.

The device requires cleaning up once in six months. The solid undigested material removed is fibrous and can be taken back to the garden as manure. Currently, the cost of installing ‘Vaayu’ is Rs. 20,000 but the operating cost is zero. There is no need of power to run ‘Vaayu’ as it operates on its own. Mr. Sahasrabuddhe is still working to improve the technology to make if more affordable.

Mr. Sahasrabuddhe has also started an informal community of like-minded nature enthusiasts who come up with innovative solutions and want to share them with others. The community, ‘Vaayu Mitra’, provides biofuel solutions according to the number of people residing in a house and encourage them to adopt a greener lifestyle. He says,

In my society, everyone segregates their own waste now. I and my friends are working also with waste collectors and are training them to operate biogas plants so that they become energy suppliers too. This increased value will help them earn better remuneration. via Waste Warriors

Sanitary Benefits of Installing an Anaerobic Digester System

The most obvious sanitary benefit of installing an anaerobic digester system is the improvements to toilet facilities in the households. Throughout China and other developing countries, where no sewer system is in place, toilet facilities are in simple shacks.

The toilet is generally a slot in the floor with either a pit underneath or alternatively a trough running to a storage pit behind the building.

In the case of a pit toilet, the slurry in the pit is often literally moving with insect larvae, and in all cases the toilets are smelly and fly infested. For these reasons, toilets are generally located as far away from the other household buildings as practical.

Watch our video below for a contrasting example of what one biogas plant supplier has achieved in sanitary improvement, using a biogas digester:

Biogas Digester Life Cycle Assessment (LCA)

Life cycle assessment (LCA) is a tool that can be used to compare the environmental impacts of different products throughout their entire life cycle (European Commission, 2010).

The LCA has been used to compare different biogas production technologies (Rehl and Muller, 2011; Poeschl et al., 2012a). Several studies have also focused on technologies for biogas production from manure and different co-substrates for manure (Hamelin et al., 2011; Rehl and Muller, 2011; De Vries et al., 2012; Poeschl et al., 2012a).

However, very few studies have focused on the vast number of small-scale biogas digesters being deployed in developing countries. Only one single study has been identified (Chen et al., 2012) and this study largely ignores the issues of CH4 leakage and release and nutrient recycling.

With the current UK calculating being done on the LCA impact of biogas production, it will soon become be easier to make comparisons with other fuels.

SimGas Biogas Systems

SimGas biogas systems are fully integrated farm solutions designed to reach millions of rural households in developing countries. Our systems enable rural households with livestock to use the manure from their livestock to generate clean fuel for cooking and organic fertiliser.

Digesters are arguably even better, though, when they're in poor or developing countries. According to the Center for Climate and Energy Solutions, small-scale anaerobic digesters like the one Porter and Mazur want to build on Everest are commonly used in rural communities to meet heating and cooking needs. China, for example, has an estimated 8 million anaerobic digesters. Nepal - where the one in question would be built - already has 50,000.

Toilet Facilities in the Households with Biogas Plants

The most obvious sanitary benefit of installing an anaerobic digester system is the improvements to toilet facilities in the households. Throughout China and other developing countries, where no sewer system is in place, toilet facilities are in simple shacks. The toilet is generally a slot in the floor with either a pit underneath or alternatively a trough running to a storage pit behind the building. In the case of a pit toilet, the slurry in the pit is often literally moving with insect larvae, and in all cases the toilets are smelly and fly infested. For these reasons, toilets are generally located as far away from the other household buildings as practical.

Reasons to Try Aquaponics

The world today uses epic amounts of non-renewable resources. as we grow old, our backs tend to give senior citizens trouble. Gardening is hard on the back. Aquaponic systems can be designed to ensure you never have to bend over to plant or harvest. lower cholesterol.

Many organizations and countries around the world are seeking to find new sustainable ways to produce food due to the world food crisis. Hydroponic and aquaponic systems have plenty of benefits for developing countries and make use of he output from digestion, known as digestate.

Unfortunately, the digested may still contain some diseases, especially when the digestate has been output after the source has been recognized as including some animal by-products.

The control of pests and diseases of plants grown in aquaponic systems is a problem since pesticide use is clearly limited by the high sensitivity of water pollution which may be caused by it.

In general, published data indicate that a digestion time of 14 days at 35 C is effective in killing (99.9 per cent die-off rate) the enteric bacterial pathogens and the enteric group of viruses. However, the die-off rate for roundworm (Ascaris lumbricoides) and hookworm (Ancylostoma) is only 90 per cent, which is still high. In this context, biogas production would provide a public health benefit beyond that of any other treatment in managing the rural health environment of developing countries.

Energy Shortages in Developed Countries

Energy shortages in developed countries turned out to have an impact on developing countries such as Indonesia (Simamora, 2006). The declining of the reserve natural energy and the increasing of human needs for living force them to always make effort and innovate to solve their problem.

A Substitute for Fossil Fuel Based Household Energy

Thumbnail image depicting the Sanitary Benefits of Installing an Anaerobic Digester System.

Any effort for a renewable substitute for fossil fuel based household energy is by developing biogas that have raw material from cattle manure. The biggest parts of Indonesia are rural area which have source income in form of integrated agriculture product, one of them is cattle, so the developing of Biogas is really potential. So far, Productivity and Socialization of Biogas energy in the countryside have not conferred maximal product outcomes.

Many developing countries, such as Colombia, Ethiopia, Tanzania, Vietnam, Cambodia, have promoted the low-cost biodigester technology aiming at reducing the production cost by using local materials and simplifying installation and operation (Botero and Preston 1987; Solarte 1995; Chater 1986; Sarwatt et al 1995; Soeurn 1994; Khan 1996).

The model used was a continuous-flow flexible tube biodigester based on the "red mud PVC" (Taiwan) bag design as described by Pound et al (1981) and later simplified by Preston and co-workers first in Ethiopia (Preston unpubl.), Colombia (Botero and Preston 1987) and later in Vietnam (Bui Xuan An et al 1994).

More than 7000 polyethylene biodigesters have been installed in Vietnam, mainly paid for by farmers (Bui Xuan An and Preston 1995).

Conclusion

Developing countries have struggled to supply stable forms of energy to many of their inhabitants.
According to the World Energy Outlook, approximately 80 percent of people without electricity live in rural areas in Sub-Saharan Africa and developing Asia.

With no other alternative for energy, many people already rely on biogas and struggle to efficiently transport and store it. The technology is therefore in a good position to be developed and extended.

Biogas in India in 2019



Introduction to Biogas Plants and Production in India

While technically biogas in India can be produced from any kind of natural product, the majority of times, biogas is produced from natural waste.

This waste might make up farming and crop waste, human waste and animal waste (cow dung for example). With a calorific worth of about 5000 KCal/ m3, biogas is an exceptional fuel for heating functions along with for producing electrical power.

Biogas production has actually been quite dominant in India at home and community levels (especially in rural backwoods) than on big scales.

In towns especially, lots of little biogas crops utilize the livestock waste (especially cow dung) and offer biogas utilized for house heating and cooking. It is approximated that over 2 million such biogas plants have actually been put into use, all through India.

When organic matters like cow dung, agricultural wastes, human excreta etc. subjected to bacterial decomposition in presence of water in absence of air, a mixture of CH4, C02, H2, H2S etc. is produced. These gases together is known as biogas. The residue left after the removal of biogas is a good source of manure and biogas is used as a good source of non-polluting fuel.

A one-cubic-meter digester, primed with cow dung to provide bacteria, can convert the waste generated by a four-person family into enough gas to cook all its meals and provide sludge for fertilizer.

A model this size costs about $425 but will pay for itself in energy savings in less than two years. That's still a high price for most Indians, even though the government recently agreed to subsidize about a third of the cost for these family-sized units.

If a biogas plant is taken care off well, it can be used for up to 25 years.

" Dr Aggarwal set up the plant at his home 4-5 years back. Describing how it functions, he shares, "Everyday, 10 kg cow dung, along with 15 litres of water, is put in the mixing tank.
"The cow dung is brought from the cowsheds from nearby areas, where the owners want to dispose it anyway. This mixture is fermented inside the fermentation tank by the anaerobic bacteria. The mixture is then converted into slurry through which methane gas and carbon dioxide gas are released," 
he shares. via dnaindia.com
Image illustrates Biogas in India
The bio-gas is obtained from plant, animal and human waste, is also called as gobar gas in India. The main source of biogas is wet cow dung.

The other sources of biogas are: sewage, crop residue, vegetable wastes, waste wood, dry leaves of the plants, broken branches of trees, garbage, waste paper, poultry droppings, pig manures, algae, ocean kelp etc.

These plants are commonly known as Gobar gas plants because the usual raw material is cow dung (Gobar). The methodology involves in the process is to prepare a slurry of cow dung with water. Water is also be added to the slurry.

Biogas in India - Conclusion

Home biogas plants produce biogas from cow dung and certain organic household waste. This allows families to cook without any worries. There is no smoke any more, and the tedious chore of collecting wood is also dispensed with. Many women and children were busy collecting firewood one day a week; now they have more time to work and play.

The systems used in the production of biogas today are not efficient. There are no new technologies yet to simplify the process and make it abundant and low cost. 

This means large scale production to satisfy a large population is still not possible. Although the biogas plants available today are able to meet some energy needs, most individuals and governments are not willing to heavily invest in the sector. This aspect has led many people to put up biomass systems in their homes, which are short on capacity.

UK FiT Fade Out - 5 Anaerobic Digestion Advantages UK Tory Ministers Ignored

First, watch our video to find out the 5 advantages government ministers ignored:



ADBA PRESS STATEMENT, Posted on 20 Jul, 2018: 

Anaerobic digestion industry response to Feed-In Tariff consultation

Responding to the government's new Feed-In Tariff (FIT) consultation, Charlotte Morton, Chief Executive of the Anaerobic Digestion & Bioresources Association (ADBA), said:
With the Feed-In Tariff (FIT) confirmed to close in just nine months’ time, this was an opportunity for the government to prove that it is committed to providing the investment that is absolutely critical to supporting small-scale renewables, which make a vital contribution to decarbonising and meeting increased demand for electricity in the UK. 
Unfortunately, this is an opportunity that has been well and truly missed. As well as providing renewable baseload power, anaerobic digestion (AD) combined heat and power (CHP) under the FIT has been vital in helping to decarbonise the farming sector. 
With the government no longer providing direct for support for the generation of renewable electricity, on-farm AD will struggle to deliver its numerous non-energy benefits, which include reducing emissions from wastes, improving air quality and resource management, and restoring soils through the production of nutrient-rich biofertiliser. 
This also puts at severe risk the more than 300 AD CHP plants currently in the planning pipeline. It’s therefore vital that the government rethinks its baffling decision to have no new low-carbon electricity levies until 2025, which risks creating a valley of death that small-scale technologies such as AD could easily fall into.
So, how did we arrive at this point?

UK FiT (Feed-in-Tariff) Fade-Out Starts on 31 March 2019

The story so far on the UK government closure of the Feed-in-Tariff (FiT) which was introduced in the 2000s to encourage the adoption of renewable energy technology in the UK.

31 March 2019, marks the date after which no more new schemes will be considered for the subsidy. 

Existing schemes will be honoured. They will still be paid-out-on over the original individual durations of scheme agreements.

Nobody would seek to suggest that overall the FiT has not been successful, given that the UK is currently not only complying with its targets for renewable energy, but exceeding them.

However, many in the UK biogas industry would argue that the FiT or a replacement scheme for biogas, should have been introduced.

This is given the youthfulness of the technology (younger in development than wind and solar technologies), and the additional benefits of anaerobic digestion, which are unique.

These are benefits which will assist the government to comply with targets for climate change abatement, air quality, and agricultural emissions for example.

In the following excerpts we have endeavored to tell the story of the FiT wind-down which was started by the UK government started in the summer of 2018.

UK's Feed In Tariff fade out confirmed

July 24, 2018: The UK’s Department for Business, Energy & Industrial Strategy has set out a proposal to close the country’s Feed-In-Tariffs (FITs) scheme.
In the proposal, the scheme would be closed to new applications after 31 March 2019. Feed-In-Tariffs are the UK government’s subsidy scheme for generation of renewable electricity from small-scale low-carbon installations. Both anaerobic digestion and combined heat and power (CHP) agricultural installations have been greatly supported by the Scheme.

The government is hosting a consultation until 13 September 2019 on the proposed changes. An impact assessment has been released to accompany the consultation.

According to the consultation, the FIT scheme was introduced to support the widespread adoption of small scale (up to 5MW) low-carbon electricity generating technologies, intending to give the wider public a stake in the transition to a low-carbon economy.

Original 2010 deployment projections, ‘both in terms of numbers of installations and installed capacity’, have been exceeded, the government reporting over 800,000 installations confirmed on the Central FIT Register as of March 2018. via Bioenergy Insight

Meanwhile other Nations have been Introducing Feed-in-Tariffs, and even increasing them, as in the following examples:

New Irish Feed-in Tariff Promotes Biogas Potential

In the course of 2017, Ireland intends to initiate the energy reform with a new feed-in tariff for renewable energies. The government plans to increase the amount of green electricity from the current figure of about 23 percent to 40 percent by 2020. 

Image shows Feed-in-Tariff Fade Out despite many anaerobic digestion advantages.
Watch on YouTube here.
The tariff system is to establish a favourable environment for biogas plant operation. In view of the extensive agricultural and waste resource potential available in Ireland, WELTEC BIOPOWER UK will showcase its AD plant technologies at the Energy Now Expo Ireland, which will be held in the end of October in The Hub in Kilkenny.

In early September, the Irish Department of Communications, Climate Action & Environment (DCCAE) announced the adoption of a new subsidy regime to promote renewable energies, to be known as the Renewable Energy Support Scheme (RESS). 

So far, Ireland has been the only European country without an incentive scheme for heat from renewable sources

However, the green island has to meet EU requirements by 2020. This means that 16 percent of Ireland‘s total energy needs for power, heat and traffic must be provided from renewable energies. This is to be achieved by making use of all green energy sources available in the country. Biogas is to play a key role especially in meeting the individual goals for the heat and transport sector. via Ireland Promotes Biogas

France increases biogas tariffs

July 31, 2015: France is set to increase its feed-in tariffs for biogas installations and small photovoltaic (PV) systems, says the Ministry of Ecology, Sustainable Development and Energy.

The feed-in tariff for electricity produced by cogeneration installations running on biogas will be raised for both new and existing installations.

On a project basis, depending on individual size and feedstock used, the increase will be between 10 and 20%.

A 300 kW anaerobic digestion unit that uses cow manure from approximately 200 cows, for example, will increase its annual income by between €40,000 and €50,000.

France recently also adopted a law to set an ambitious target of sourcing 32% of its energy demand from renewable sources by 2030. via BioenergyInsightMagaz

Feed-in tariffs in Australia - Solar Only

Feed-in tariffs in Australia are the feed-in tariffs (FITs) paid under various State schemes to non-commercial producers of electricity generated by solar photovoltaic (PV) systems using solar panels. 

They are a way of subsidising and encouraging uptake of renewable energy and in Australia have been enacted at the State level, in conjunction with a federal mandatory renewable energy target.

Australian FIT schemes tend to focus on providing support to solar PV particularly in the residential context, and project limits on installed capacity (such as 10 kW in NSW) mean effectively that FITs do not support large scale projects such as wind farms or solar thermal power stations. via Wikipedia

FiT in Japan

Since its enforcement in 2012, purchase prices of FiT have been re-examined every year. As a result, that for solar PV has been lowered and some new categories have been created for wind, hydro and biomass.

On April 2017, the FIT scheme was partially amended. This amendment introduces a new approval system for renewable power generation projects that require grid connection agreement with the utility beforehand. via Solar PV auction

No FiT Schemes Exist in the US - Only Renewable Portfolio Standards


A state renewable portfolio standard (RPS) encourages or requires utilities to use or buy renewable energy or renewable energy certificates (RECs) to account for a certain portion of their retail electricity sales by a certain date. A REC is a tradable certificate documenting that 1 megawatt-hour of renewable electricity was generated at a specific facility. The goal of an RPS is to stimulate market and technology development so that renewable energy can become more competitive with conventional forms of electric power. A state RPS helps create market demand for renewable energy.

Generally, electricity suppliers can meet the RPS targets by:
Owning a renewable energy facility and its output generation.
Purchasing RECs.
Purchasing electricity from a renewable facility.

Biogas from anaerobic digesters often qualifies as renewable energy under the biomass category of state RPS systems. via AgSTAR

Fugitive Emissions of Methane Biogas and Landfill Gas Explained



Fugitive Emissions of Methane

Fugitive Emissions of Methane (Biogas and Landfill Gas) Explained

It is well known that unintentional escapes of methane and landfill gas (fugitive emissions) occur when methane escapes from a myriad of tiny leaks from production facilities, wells, pipes, compressors and other equipment.

Methane continually escapes through tiny leaks from the equipment associated with coal mining or natural gas extraction, landfills, landfill gas utilization plants, and biogas plants.

It is obviously very important to reduce all these fugitive methane emissions to an absolute minimum.

Methane is more than 80 times more damaging to the atmosphere and more powerful than carbon dioxide over a 20-year time frame.

It's the second leading contributor to climate change, after carbon dioxide.

Methane accounts for approximately 25 % of the world’s climate warming.

Accidentally released methane emissions are the inevitable byproduct of the oil and gas industry and agriculture, and occur from all methane equipment.

But, not only from equipment it also gets released when cattle blow-off!

Vegans are right when they say reducing demand for dairy and meat will help the environment.

80 % of the Geenhouse Gas (GHG) emissions due to enteric fermentation (digestion in stomachs) are from the digestive systems of cattle.

But, that's enough about cattle emissions, what about biogas plants which imitate cattle to make methane.

Unintentional emissions will be occurring from all biogas plants.

Storage tanks inevitably leak a small amount, as do pipe joints, valves and other equipment.

Other fugitive emissions will occur when digesters are opened-up for maintenance, and during commissioning.

However, biogas plant and landfill gas utilization plants would be expected to be similar to those for the natural gas supply industry.

Fugitive emission research conducted within the natural gas industry estimates the US national methane fugitive emissions rate for natural gas at about 0.42%.

A not insignificant amount overall, and it needs to be reduced.

However, the amounts are tiny when compared with the fugitive emission of methane from cattle, and landfills.

Municipal solid waste landfills are the third-largest source of human-related methane emissions in the United States, accounting for approximately 15% of these emissions in 2016.

Similar figures apply to all developed nations.

But, as Vegans can point out.

This is well below the 26% emitted from cattle through enteric fermentaton.

Thanks for watching right through!
