IADAB News Weekly - Edition 5: Biogas Powered Fuel Cell Emissions Approval, UK ADBA and RHI Renewal, Plus Biochar Synergies

The IADAB Anaerobic Digestion and Biogas News Weekly - Issue 5: 20 October 2017

This is Issue 5 of the IADAB News Weekly where we summarise the most important news of the week in the developing world of the Anaerobic Digestion and Biogas Industry in the UK and globally.

IF YOU WANT A SUMMARY OF THE CONTENTS OF THIS NEWSLETTER WATCH THE FOLLOWING VIDEO. OTHERWISE SCROLL DOWN TO READ THE MORE DETAILED VERSION.


The most popular news this week has been that a US fuel cell Energy Power Plant using on-site anaerobic digester gas, has achieved Certification from the California Air Resources Board Distributed Generation (DG) Clean Air Standards certification authority, and is good news for the future wide-scale adoption of large scale fuel cells for biogas energy electrical conversion.

Second on our list has been the article by ADBA pointing out to the UK government that, following the publication of their strategy document last week, "anaerobic digestion can underpin the UK's Clean Growth Strategy". The fine words made in the strategy, now creates the need for urgent tabling of legislation on the Renewable Heat Incentive to renew support for biomethane-to-grid.

Our third article this week, is chosen for running third in the popularity stakes on Facebook, and holds an unusual subject for the AD industry, this being; Synergies between Anaerobic Digestion and Biochar

Apparently carbonizing the anaerobically digested fibers could be a viable way to create adsorbent for the removal of soluble phosphorous from Anaerobic digesters effluents.  

The IBI Educational Webinar will discuss using biochar in the AD substrate to boost not only the quantity but also the quality of the methane produced.  It is also claimed that the biochar can reduce the H2S generated during the AD process thereby reducing wear and tear on equipment.

Finally, we reference two articles in the "also of interest" category for biogas plant opaerators especially, on the subject of whether or not microbial communities in an anaerobic bioreactor change with continuous feeding sludge into a full-scale anaerobic digestion system. Personally, the author would be surprised if they don't evolve in our modern mechanical digesters.

Now we suggest that you scroll down and read further about these subjects:

1. FuelCell Energy SureSource Power Plant Using On-Site Anaerobic Digester Gas Achieves Certification for California Air Resources Board Distributed Generation (DG) Clean Air Standards

This certification acknowledges the clean air profile of SureSource solutions, facilitating the air permitting process, which reduces costs and supports client sustainability goals.
FuelCell Energy design, manufacture, undertake project development, install, operate and maintain megawatt-scale fuel cell systems, serving utilities, industrial and large municipal power users with solutions that include both utility-scale and on-site power generation, carbon capture, local hydrogen production for transportation and industry, and long duration energy storage. With SureSource™ installations on three continents and millions of megawatt hours of ultra-clean power produced, FuelCell Energy is a global leader with environmentally responsible power solutions.

Municipal wastewater treatment applications for the SureSource solution are based on a comprehensive approach that enables the municipality to outsource the operation and maintenance of the fuel cell power plant as well as biogas treatment, which is also provided by FuelCell Energy using the company’s proprietary technology for biogas treatment and fuel quality monitoring. The versatile SureSource solution can utilize on-site renewable biogas or directed biogas as a fuel source and is the only fuel cell or other type of power generation technology to gain CARB certification to the 2013 Waste Gas standard using on-site biogas.

SureSource power plants are uniquely suited for operation utilizing on-site biogas since the system is able to use the low-Btu gas without a de-rating of power plant output, and the power plants produce usable thermal energy which can support the digester operation. Power produced by the system can be used on site or sold to the electric utility under tariffs such as California’s BioMAT feed in tariff. A modification of the technology is available in which the power plant produces vehicle-grade renewable hydrogen in addition to power and heat, supporting the developing infrastructure for fuel cell vehicles.

“We have gained extensive experience working with a number of municipal water treatment facilities": said Frank Wolak, Vice President Sales-Americas. via FuelCell Energy SureSource Power

2. PRESS RELEASE: Anaerobic Digestion Can Underpin Clean Growth Strategy - Urgent RHI Renewal Needed – ADBA

The Anaerobic Digestion & Bioresources Association (ADBA) has welcomed the Clean Growth Strategy published by the Department for Business, Energy and Industrial Strategy and said that anaerobic digestion (AD) can play an underpinning role in meeting the strategy’s goals.

ADBA Chief Executive Charlotte Morton said:
"The multi-faceted nature of AD means that, with the right support, it can play a central role in decarbonising heat, electricity, transport, and farming, as well as increasing energy and food security and restoring the UK’s degraded soils. No other technology can make such a key contribution to so many different areas of the Clean Growth Strategy."
We welcome the government’s ambition to divert all food waste from landfill by 2030 and to support local authorities in rolling out separate food waste collections.

We look forward to BEIS’s new Resources & Waste Strategy, which will need to be supported by meaningful funding and legislation to effect the scale of change needed for an urgent transition to a more circular economy.

We also welcome the strategy’s highlighting of the importance of best practice in AD. ADBA’s pioneering, industry-led Best Practice Scheme, which will be launched in full later this year, will help support AD operators in meeting the highest environmental, health and safety, and operational standards.

The publication of the Clean Growth Strategy today is a welcome sign that the government is starting to think about how we can make the deep emissions cuts that will be necessary to meet the Fourth and Fifth Carbon Budgets over the next 15 years. 

What is needed now is tangible support for AD in the form of the following:

Urgent tabling of legislation on the Renewable Heat Incentive to renew support for biomethane-to-grid;
  1. A long-term replacement for the Feed-In Tariff to support small-scale renewable electricity generation;
  2. Mandatory separate food waste collections in England to allow AD to recycle this vital and underused resource; and
  3. A new support system for farmers that rewards carbon abatement and incentivises the use of biofertiliser to restore soils.

3. IBI Educational Webinar Series: Synergies between Anaerobic Digestion and Biochar

Research has shown that there are many synergies to be found integrating pyrolysis and gasification with anaerobic digestion (AD) systems.  Carbonizing the anaerobic digested fibers could be a viable way to create adsorbent for the removal of soluable phosphorous from Anaerobic digesters effluents.

Using biochar in the AD substrate can boost not only the quantity but the quality of the methane (CH4) produced.  It can also reduce the H2S generated during the AD process thereby reducing wear and tear on equipment.  In the webinar we will discuss the possibilities to integrate acidic biochars with dissolved air flotation systems for ammonia removal. 

The focus of this webinar is on pyrolysis and gasification, two technologies that are capable of converting the digested fibers into a bio-char, and that can be integrated with AD.  

During the presentation Dr. Garcia-Perez will also discuss some of the potential uses of these chars in anaerobic digestion systems.

The webinar on October 30, 2017 • 3:30 – 5:00 pm ET, costs $40 to attend, via IBI Educational Webinar Series: Synergies between Anaerobic Digestion & Biochar
