IADAB News - Edition 15 - UK Food Waste Company Take-over Irish WWTW AD Plans and Biogas Buses

Date: 11 February 2017: This is Issue 15 of the IADAB News Weekly, where we summarise the news of the week in the Anaerobic Digestion and Biogas Industry.
Image shows: Biogas News plus Anaerobic Digestion News

This week we are featuring 4 UK events in the AD scene in the UK, and one in the US. These are chosen as being the items which have scored most highly based upon the last seven days of social network interaction across Twitter, Facebook, and Linked-In (provided by Kudani).

The first item is the surprise acquisition of Tamar Energy by Biogen, which amounts to a substantial re-alignment of food waste AD capacity in the South of England. It may help reduce the downward trend in gate-fees for Food Waste disposal in the south of the UK, but that will remain to be seen.

Next, in Ireland there is good news for growth in AD, during Irish Wastewater Treatment Plant (WWTP) upgrades. When these are completed, it is proposed that the number of sites with anaerobic digestion will increased by 5.

Next, we have a new US item. the Connecticut Department of Energy and Environmental Protection (DEEP) issued a request for proposals to procure up to 899,250 MWh/year of renewable energy, and our reading of the request is that AD bids could make up the lion share, if companies put AD plant options in their proposals. There is not much time though with a short deadline for bidders to make their submissions.

Finally, we have two UK items. The first is an ADBA post in which it joins an industry-wide call for the government to issue a long-awaited FIT consultation, so that much needed confidence in continuity of the subsidy scheme can return and allow investment to flow into new projects.

Our fifth and last item is welcome. £40 million will awarded to Councils for low emission buses. Using the money councils will be able to retrofit vehicles with technology to reduce tailpipe emissions of nitrogen dioxide. Retrofitting buses to use biomethane as a vehicle fuel offers a carbon reduction and can help reduce air pollution.

The following is our intro video. Watch the intro video below, for a taster of what you will read if you scroll down below the video:

1. Biogen Acquires Tamar Energy

Biogen has expanded its food waste recycling network through the acquisition of Tamar Energy, one of the largest anaerobic digestion (AD) owners and operators in the UK. The acquisition was completed by Ancala Partners LLP, the independent mid-market infrastructure investment manager for an undisclosed sum. 

A number of Tamar Energy's existing shareholders have rolled-over their investment into the combined group. The acquisition creates one of the largest independent AD operators in the UK. via anaerobic digestion food waste industry food waste management renewable energy

2. Ambitious Plans for More Wastewater Anaerobic Digestion Plants in Ireland

Maximising energy recovery from sludges through anaerobic digestion is at the heart of Irish Water’s National Wastewater Sludge Management Plan:

“There are 14 wastewater treatment plants in Ireland with anaerobic digestion currently in operation. More than 50 per cent of all wastewater sludge was anaerobically digested in 2014. This is expected to increase to approximately 65 per cent when WWTP upgrades, currently under way, are completed. It is proposed that the number of sites with anaerobic digestion is increased to 19, as the optimum strategy for treatment, with the biogas produced used for energy recovery in all cases.
Advanced anaerobic digestion followed by reuse of the residual bio-solids on land has been evaluated to be the most sustainable solution for wastewater sludge treatment and disposal.” via bridging skills gap

3. Connecticut Issues New RFP For Offshore Wind, Fuel Cell, And Anaerobic Digestion Projects

Last week, the Connecticut Department of Energy and Environmental Protection (DEEP) issued a request for proposals to procure up to 899,250 MWh/year of renewable energy and associated Renewable Energy Certificates (RECs) from offshore wind, fuel cell, and anaerobic digestion renewable energy resources, pursuant to long-term contracts of up to 20 years. Bidders must submit completed proposals to DEEP by April 2, 2018. Connecticut will announce winning bids in June 2018. via Connecticut Issues New RFP

4. ADBA joins industry-wide call for long-awaited FIT consultation

ADBA has today joined a number of trade associations to write to Rt Hon Greg Clark MP, Secretary of State for Business, Energy and Industrial Strategy, regarding the long-awaited Feed-in Tariff consultation.

The letter highlights the contribution renewables technologies supported under the FIT make to UK energy and carbon targets. With the FIT scheduled to close to new applicants in March 2019, the letter calls on BEIS to address the uncertainty this cliff-edge end date poses, by working with industry to deliver alternative routes to market.

In support of the letter Charlotte Morton, Chief Executive of ADBA, said:

The UK’s anaerobic digestion (AD) industry has already delivered so much, powering over a million homes and reducing the UK’s greenhouse (GHG) gas emissions by 1%, particularly in challenging areas such as agriculture. With the right support, however, it could meet 30% of current household electricity demand, quadruple its contribution to reducing UK GHG emissions, and provide 30,000 rural jobs. While AD is an established technology, the absence of a FIT post March 2019 is a serious threat to the viability of the UK AD industry and its ability to contribute to meeting a wide range of policy goals. We urge BEIS to set out a sustainable future for small-scale, low-carbon energy projects such as AD beyond 2019 to give reassurance to what is such a crucial industry for meeting climate goals in the UK. via ADBA

5. £40 million awarded to Councils for low emission buses

As part of the Clean Bus Technology Fund, which was launched in 2017, the Joint Air Quality Unit has today announced awards totalling £40 million to local authorities across the UK to support efforts to improve air quality in UK towns and cities. Using the money councils will be able to retrofit vehicles with technology to reduce tailpipe emissions of nitrogen dioxide. Although much of the recent in the vehicle sector has come on the OEM side, retrofitting buses to use biomethane as a vehicle fuel offers a carbon reduction and can help reduce air pollution.

Road transport is going to change dramatically over the next couple of decades – and we have to make sure that the bus industry is ready to benefit from those changes.

What is a Manure Pond and How to Use Lagoon Biogas

So you want to know: What are Manure Ponds and How to Use the Lagoon Biogas which an unmixed lagoon produces naturally.

Definition of "What is a Manure Pond"

A farm manure pond or lagoon is a man-made outdoor earthen basin filled with animal waste.

They are created from the manure slurry, which is washed out from underneath animal pens and piped into the pond.

A foul smelling gas called biogas is produced, and the majority of the gas is methane.

Some farmers cover their manure ponds to capture the biogas, and reduce odours.

Image illustrates What are Manure Ponds and How to Use Lagoon Biogas.
A floating plastic membrane cover, which wll hold the gas until it is needed, and pipes to collect the gas, are all that is needed for the simplest systems.

The methane in the biogas can be used for heating and for generating electricity on the farm.

Other farmers go to great lengths to produce biogas in large tanks called digesters where they put manure and used bedding material from their barns.

 However, to use the biogas from a simple manure pond can be worthwhile financially especially in warm climates, and will help reduce climate change by reducing damaging greenhouse gas (methane) emissions.

IADAB News - Edition 14 - Biomethane Developments + New UK RHI Scheme Update

Date: 4 February 2017: This is Issue 14 of the IADAB News Weekly, where we summarise the news of the week in the fast developing Anaerobic Digestion and Biogas Industry.
Image shows: Biogas News plus Anaerobic Digestion News

This week we are focusing on events in the biogas plants which upgrade their raw biogas and sell it as biomethane.

First we include news from the Dutch that the first biomethane has been injected into the gas grid at the Microferm project in Deurningen (NL).

Second, California is moving toward adopting the European Model of biomethane production and gas grid injection of the output with the news that 5 pilot projects will go ahead to identify a largely untapped energy resource, and put organic waste to work for California. This is an exciting first step to building the market for renewable natural gas in the US state.

Third, and the most exciting, given the prospect that another huge biogas feedstock source "straw" is now looking possible to add to the rising number of waste biomass sources which can be disposed of, while also producing renewable energy. 
A happy woman is pleased about producing biogas and biomethane from straw.

Yes! Biomethane from only straw! 

The new VERBIO technology makes it possible to leverage a massive potential raw material source which has been unused to date.

Next, we feature our video on the AnaerobicDigestion YuTube Channel where we explain "What is a Biogas Upgrade? and purification of biogas to biomethane.

Followed by a reminder that RTFC Price Information within the anaerobic digestion and biogas industry is now available from markets expert Energy Census [RE]fuel (currently at no charge).

UK Biomethane and the Long Awaited New RHI Scheme

Image illustrates our Update on the UK government's RHI Scheme.
UK biomethane progress has been almost halted throughout 2017, with only 2 new projects started. The reason is the delay in issuing the new Renewable Heat Incentive (RHI) rules, with the promised improved incentive rates for biogas plants making biomethane.

The New RHI was expected in March 2017, but it was delayed due to a drafting error and then due to the snap UK government General Election in June.

The new RHI is now expected to be announced during the current quarter. Expert John Baldwin predicts 30 to 40 UK biomethane projects in the next 2 to 3 years, subject to the life of the RHI when the announcement is made.

Alright, let’s get started… (Scroll down for each extract and use the links to the full articles on each of the individual websites.)

The following is our intro video. Watch the intro video below, for a taster of what you will read if you scroll down below the video:

1 - First biomethane injected into gas grid at Microferm project in Deurningen (NL)

The first biomethane was injected into the Dutch national gas grid on Friday December 22 at the Microferm project ‘Broekhuis Koegas’ in Deurningen in the Netherlands. The installation produces 40 Nm3 biomethane per hour. HoSt is turn-key supplier of the installation.

California Utilities Issue Draft Solicitation for Dairy Biomethane Pilot Projects

LOS ANGELES, Jan. 19, 2018 /PRNewswire/ -- Southern California Gas Co. (SoCalGas), San Diego Gas & Electric (SDG&E), Pacific Gas and Electric Company (PG&E) and Southwest Gas jointly issued a draft solicitation yesterday for dairy biomethane pilot projects under California Senate Bill (SB) 1383. Proposed projects must demonstrate an ability to capture and process biogas from dairy cows to produce renewable natural gas, which can replace traditionally sourced natural gas for generating electricity, heating homes and fueling vehicles. At least five projects will be selected.
The draft solicitation is the first step in a new program created under SB 1383 by the California Public Utilities Commission (CPUC), which has been directed to reduce methane emissions from agriculture in the state by 2030.
"This is an exciting first step to building the market for renewable natural gas," said Lisa Alexander, vice president of customer solutions and communications for SoCalGas. "Renewable natural gas, with its ability to turn methane emissions into a source of energy, is a critical element of a comprehensive approach to climate change, and we look forward to supporting these efforts."
"The capture of biogas from agriculture is an innovative way to produce renewable natural gas to fuel our homes and businesses while helping achieve the state's climate goals," said Michael Schneider, chief environmental officer and vice president of operations support and sustainability for SDG&E. "These pilot projects will help us identify a largely untapped energy resource and put organic waste to work for California."

Biomethane from only straw? | European Bioenergy Day

Through the support of the European Union, VERBIO Vereinigte BioEnergie AG has developed an innovative production plant for biomethane that is manufactured from 100% straw. VERBIO  has reached the first project milestone on schedule, feeding the first gigawatt hours of biomethane generated from 100% straw since October 2014 into the local natural gas network operated by Stadtwerke Schwedt. “Straw bio-methane technology is a clear demonstration that second generation biofuels using local supply chains are no longer a thing of the future, but are today’s reality,” commented Dr. L├╝dtke, Chairman of the Management Board of VERBIO AG.

VERBIO AG has been the operator of two large biomethane plants since 2011, each with a capacity of 30 MW. These plants produce approximately 480 GWh of biomethane from distillation slop, a waste raw material by-product generated from bioethanol production, with the resulting biomethane used as biofuel for vehicles powered by natural gas. With the volume produced VERBIO supplies more than 100 of the 900 natural gas fuel stations in Germany, making it the unchallenged market leader in this segment.
The new plant, also developed internally, is based on mono straw fermentation technology. The plant will be extended to reach 16,5 MW capacity by the year 2019, generating 140 gigawatt hours of biomethane annually for sale as biofuel from approximately 40.000 tons of straw. To date, EUR 25 million has already been invested in the construction of the plant. Further amounts will be invested in the coming years to optimise the plant. The straw used to fuel the plant is gathered within a radius of 80km of the plant to ensure maximum economic and ecological efficiency. In exchange, the fermentation waste is provided to farmers as organic fertiliser. This local production chain creates employment in the region’s agricultural sector and ensures maximum CO2 efficiency.
The new VERBIO technology makes it possible to leverage a massive potential raw material source which has been unused to date. In Germany alone, an annual quantity of between 8 and 13 million tons of straw that could be used to manufacture bioenergy currently remain unused according to a study by the DBFZ (German biomass research center). This energy quantity represents the fuel required annually by more than 5 million motor cars. via Biomethane from only straw?

Spanish company unveils innovative project to produce biomethane

Valoriza Agua is executing the Smart • Met • Value research project to obtain a renewable and local biofuel through biogas production processes that take place in the wastewater treatment plants (WWTP).
The project, which is being carried out in the WWTP that Valoriza Agua manages in Guadalajara, consists of the design of a cleaning system for the biogas that is generated in the anaerobic digestion processes that take place in these facilities to obtain a biomethane with quality for its network injection and other uses such as transport. With HAM technology, the company already offers supply of this renewable fuel to vehicles.
The Smart • Met • Value includes four differentiated technological goals: development of a gas absorption model for biogas; development of a methane purification technology of high efficiency but with energy consumption significantly lower than currently used, obtaining a prototype for the mixing of gases, obtaining biomethane that complies with the current regulations (PD001).

What is a Biogas Upgrade? Purification to Biomethane

The biomethane produced with biogas upgrading technology has the same specifications as natural gas, which makes it fully compatible to the existing natural gas infrastructure and applications. Optionally, the CO2 by-product can be recovered for use in a variety of applications.

Bio-fuel Market Prices - 3 Reasons UK Biomethane Producers Watch Them

Like it or not, biogas and especially biomethane producers should start to take a keen interest in Bio-fuel Market Prices, and here is our list of 3 reasons why.
“UK Biomethane producers and potential “biogas-plant to biomethane upgraders”, should be watching bio-fuel market prices closely.”
That’s because many foresee big gains in the prices they will in future be likely to get for biomethane sold with an associated RTFC certificate into the road transport fuel market.
RTFC Price Information within the anaerobic digestion and biogas industry is now available from markets expert Energy Census [RE]fuel (currently at no charge), which already indicates that for much of 2017, producers could obtain something of the order of magnitude of double the payment per kg which is commonly obtained from selling it now into the heat market.

First UK AD Plant Certified Under New Performance Scheme is Granville Ecopark

AD Plant Certification Scheme

It seems like no time at all since I attended the ADBA conference session at which their AD Plant Certification Scheme as launched in the first week of December, in London, and already the first certificate has been issued.

The first business to be awarded under the scheme is Granville Ecopark. They become the first UK AD plant certified under the new performance scheme.

The scheme has been launched after about 2 years spent by an ADBA member committee in consulting on the essential elements of Anaerobic Digestion facility design and operation good practise.

The aim of the scheme is to help raise the overall standards of operation of UK biogas plants, in all areas.

The group founding the scheme has found that a major benefit for those operators who qualify will be lower insurance charges, and there have been suggestions that the cost of becoming certified will frequently be more than offset by reductions in insurance charges for Certified AD Facilities.

A copy of the full ABDA Press Release follows:

Northern Irish plant treats organic waste to produce renewable energy Plant is first to be certified under new Anaerobic Digestion Certification Scheme Scheme was launched just six weeks ago at the ADBA National Conference 2017 Granville Ecopark, an award-winning enhanced anaerobic digestion (AD) facility based in Northern Ireland, has become the first AD plant in the UK to achieve certification under the recently launched AD Certification Scheme (ADCS), an industry-led initiative that recognises good operational, environmental, and health and safety performance at AD plants.

The scheme was launched just six weeks ago at the Anaerobic Digestion & Bioresources   ssociation’s ADBA National Conference 2017 following a successful pilot earlier in the year  involving three different AD plants. The ADCS has been developed in collaboration with a range of industry stakeholders including regulators, insurers, investors, and operators and is managed by ADBA, the UK’s trade body for AD.

Granville Ecopark is the largest AD facility in Ireland taking only food waste as a resource and has capacity to export 4.8 MWe of renewable electricity onto Northern Ireland’s local grid. Recent expansion now allows the plant to clean up excess biogas into biomethane, which is being transported all over Northern Ireland to power CHP engines and create renewable heat and electricity for its customers.

David McKee, Technical Director at Granville Ecopark, said:

We are delighted to be the first UK AD plant certified under this new scheme. It gives us the confidence that we are attaining the highest standards within the industry and will drive us forward to remain at the top. We hope that others will now follow in our footsteps and apply for certification to help boost their environmental credentials and further highlight how important the AD industry is for the future of renewable energy throughout the UK.

Nick Johnn, Director at Aardvark Certification Limited, the ADCS’s official certification body, said:

We’re delighted to announce Granville Ecopark as the first AD plant to be certified under the ADCS. Aardvark was proud to be appointed as the first and currently only certification body for the scheme, which we see as vital to assuring performance and raising standards in what is such an important industry. It was great to receive Granville Ecopark’s application so soon after the ADCS was launched at the ADBA National Conference 2017 back in December, and this will hopefully be the first of many applications. We look forward to working with many more AD plants who are looking to demonstrate that they are meeting high operational, environmental, and health and safety standards.

Charlotte Morton, ADBA Chief Executive, said:

To have the first plant certified under the ADCS just six weeks after the scheme was launched is hugely encouraging and shows the support within the AD industry for raising its performance across the board and recognising good practice in running plants. ADBA will continue to speak to AD operators about the many benefits of the ADCS both for operators themselves and for the wider industry, including increased support from politicians, regulators, insurers, and investors.

In September 2017 Granville Ecopark also became the first AD plant to obtain a Prosperity Agreement with the Northern Ireland Environment Agency whereby the two parties have pledged to work together to develop innovative solutions to maximise energy production and work with the community to deliver environmental initiatives. Amidst this success Granville Ecopark has also been recognised as Market Development leaders with a prestigious award from Sustainable Ireland for its work in food waste and the circular economy.

5 Anaerobic Digestion Problems to Avoid in Commercial Biogas Facilities

These Anaerobic Digestion problems are potentially serious, however, through the good management of modern commercial biogas plants they are easily avoided.

Avoidance of these problems through the use of monitoring equipment, and taking early corrective action whenever these problems begin to appear, is the routine day to day task of the experienced biogas plant operator.

For the full article visit our website:

Now we will look at each anaerobic digestion process problem, one by one:

1 – Foaming

Anaerobic digestion foaming is one of the most common anaerobic digestion problems. It is an operational problem in biogas plants with negative impacts on the biogas plant’s economy and environment.

Foaming incidents can last from one day to three weeks, causing 20-50% biogas production loss, unless early corrective action is taken.

2 – Acidification

This second of our listed anaerobic digestion problems is more correctly referred to as “over-acidification”, because acidification is in itself an important stage in healthy anaerobic digestion.

It is one of the most expensive problems, and if not corrected, can in the worst cases can take months until the digester biology recovers, and digester performance is restored.

Nearly always an overload of the digester biology is the cause for an acidification. Frequently, the problem has nothing to do with the loading rate of the digester, and other factors are the root cause.

3 – Increasing Viscosity

Floating layers form and stirring and mixing flows deteriorate.

The result is poor material transport and defective degassing, this often also leads to elevated plant energy consumption and increasing wear and tear on agitator/ mixing equipment.

In extreme cases, if the condition is allowed to persist, major mixing pump damage, and complete production outages can occur.

4 – Increasing VFA and TIC Value

An increasing VFA (Volatile fatty acids) and at times also in the TIC (Alkalinity, total inorganic carbonate buffer) value, may occur when the organic loading rate (OLR) is increased above a long-term stable rate. The biogas process becomes unstable, due to accumulation of volatile fatty acids (VFA), and/ or a non-optimum elevated (alkaline) pH.

Biogas output is impaired if the accumulation of volatile fatty acids (VFA) is sufficiently elevated, resulting in a process slow-down and further VFA accumulation in a worsening cycle, unless the OLR is reduced.

5 – Low Methane Yield

Lower than anticipated methane yield is very often the first indication of other problems, so it is important to continuously monitor the percentage of methane and other gases such as hydrogen sulphide (H2S), as an early-warning of the need to make adjustments to the digester operation.

Low methane yield is merely a symptom of other problems, and is only included here for completeness.

Conclusion – Anaerobic Digestion Problems Seen in Commercial Biogas Plants

Taking expert advice from an AD process expert "troubleshooter", or the AD Plant's Construction Contractor's in-house process experts, as soon as first signs of anaerobic digestion problems appear, is the recommended solution.

UK Government Environment Plan's Soil Health Goal Gets Anaerobic digestion Industry Welcome

This new goal for all England’s soils to be managed sustainably by 2030 is a “step in right direction”

Anaerobic digestion process produces nutrient-rich biofertiliser that restores soils.

However, the lack of action on food waste collections in these plans must be seen as a “missed opportunity”.

"Incentives needed for farmers to use sustainable biofertiliser".

Watch our video on this subject below, but don't forget to return here to also SCROLL DOWN, and read our much more in-depth Press Release:

In these times of almost total Brexit obsession, UK citizens must be thankful good to hear of any of the many badly need initiatives the UK needs, to tackle some really big environmental problems, being moved forward.

While the mainstream environmental news today in the UK today is all about Theresa May's measures to reduce the peril of Plastic Packaging waste to wildlife, the news we provide here msut be of equal importance, given that good soil quality is essential to agricultural production. We all have to eat!

Anaerobic digestion is the one process which can deliver on soil quality, while not simultaneously raising the nations energy demand and at the same time also raising carbon emissions.

Composting may produce great soil improvements as well, but can only be achieved on a large scale by the adoption of windrow methods which need energy consuming plant to accomplish and for guaranteed Animal-by-Products regulations compliance forced ventilation (eg in in-vessel composting tunnels) which is an even bigger energy consumer.

Therefore, this goal will mean more reasons for all types of biomass/ organic waste to be treated by the Anaerobic digestion Process.

Anaerobic digestion industry welcomes Environment Plan soil health goal

ADBA Press Release:

The UK’s anaerobic digestion (AD) industry has welcomed a target from the Department for Environment, Food and Rural Affairs (Defra) for all of England’s soils to be “managed sustainably” by 2030, calling it “an important step in the right direction” towards restoring the UK’s soils.

Defra’s 25-year environment plan, published this morning, calls for “good nutrient management practices” in soil management and pledges to work with industry “to encourage the use of low emissions fertiliser”. It also pledges to create “meaningful metrics” to assess soil improvements and to “develop cost-effective and innovative ways to monitor soil at farm and national level”.

Charlotte Morton, Chief Executive of the Anaerobic Digestion & Bioresources Association (ADBA), said:
“The health of the UK’s soils is critical to allowing us to grow the food we need to feed our families. Defra’s aim to restore soil sustainability in England is an important step in the right direction, and the AD industry can play a key role in this through producing natural, low-emission biofertiliser in the form of digestate, which is high in vital nutrients such as nitrogen, phosphorous, and potassium.
“The government now needs to provide meaningful incentives for farmers to buy and use biofertilisers that help to restore soils and reduce emissions from agriculture. Providing support for AD plants, which produce these digestate-derived biofertilisers, is therefore essential.”

Despite the environment plan covering resource efficiency and waste, there were no new commitments on separate food waste collections, which as many as half of local authorities in England still do not offer to residents.

AD plants recycle unavoidable and inedible food waste into renewable heat and power, low-carbon transport fuel, and biofertiliser, and have the potential to meet 30% of the UK’s domestic gas or electricity demand. Evidence from Wales, Scotland, and Northern Ireland, which all have mandatory food waste collections, also shows that households and businesses that separate food waste tend to produce less waste due to greater awareness.

Charlotte Morton added:

“Despite rightly identifying recycling food waste as a ‘key priority’ in today’s plan, Defra’s failure to commit to rolling out mandatory separate food waste collections in England is a missed opportunity to reduce food waste levels and allow AD plants to produce the renewable energy, transport fuel, and biofertilisers that we as a country desperately need.
“With European Union members having recently committed to mandatory separate collection of biowaste (i.e. food waste) by 2025 and the UK devolved administrations already having rolled out such collections, England is lagging behind and losing out as a result. The consensus around the need for separate food waste collections in England is building, so we hope to see more concrete policies to support this development in the government’s forthcoming Resources & Waste Strategy.”

Why UK AD Plant Owners Need Updated RTFO Biomethane Price Information

RTFO Biomethane Price Information - weekly [RE]fuel Reports
It is no secret that the UK government is committed to ambitious targets for decarbonising road transport, while simultaneously reducing crop based diesel bio-fuel production. It has to be able to show rapid increases in renewable energy use in transport, to have any hope in maintaining credibility for its pledges for climate change reduction.

Despite the current price being low for RTFO Certified Biomethane and comparatively little biogas being sold as such, there is a good chance that this will soon change.

The year 2018, may be the year when government and commercial imperatives come together to create a level of demand which will raise prices paid for biomethane, reduce current price volatility, and make supplying energy into the transport sector attractive to AD plant owners.

However, until quite recently there were no freely published, regularly updated, (weekly) figures which those in the anaerobic digestion and biogas industry could monitor for the RTFC-RHI spread (waste based biomethane).

Start-up company Energy Census has identified this as a potential opportunity, and is plugging the gap in the available published market price information with their weekly [RE]fuel report

It is offering regular free [RE]fuel, bio-fuel market price reports from their website at 

The spreads that [RE]fuel are publishing in their current reports (RTFC-RHI) show the difference in pence per kwh and pence per litre between what an AD plant would receive for their gas if they were to supply into the transport sector vs the heating sector – ie, at current prices (December 2017), they would get twice as much per unit of gas sold, if they supply into transport.
Andrew Goodwin ( [RE]fuel MD) said:
“Energy Census is delighted to be able to offer a RTFC pricing service to help minimise financial risk for the anaerobic digestion and bio-resources industry at this time of growing production. We look forward to serving the industry as it grows to became a highly significant player, providing much needed renewable fuel into the renewable transport market. This market growth is one which with others will help the global community achieve the decarbonisation (CO2 emissions reductions) essential to attaining the UK’s climate change targets.”
We have published a more detailed assessment of How AD Plant Operators Can Sell Biomethane Into the Bio-fuels Market and Make the RTFO Work for Them - on our main blog here. Visit that article now to understand why AD plant operators, and related biogas professionals need to keep themselves informed about this, or possibly miss out on an opportunity to improve their biogas income.
