RENEWABLE NATURAL GAS AND COGENERATION AB ENERGY ADDS BIOCH4NGE® IN NORTH AMERICA

​Pine Brook NJ – October 19, 2020: With an ever growing demand for cleaner energy sources and CO2 reductions, Renewable Natural Gas (RNG) is the hot topic for discussion and action across North America.

RNG, also known as biomethane, is a refined natural gas arising from biogas produced from the
bacterial breakdown of organic waste materials through anaerobic digestion. The sources of organics
are commonly food and food processing waste, farm animal and plant waste, select industrial
wastewaters, and municipal sewage.

This clean industry is experiencing massive growth fuelled by the development of technologies and
processes designed to extract this valuable and renewable energy resource. It is heavily supported
by major organizations, e.g. the American Biogas Council, who provide purity and interconnection
guidelines to ensure uniform standards, allowing for the RNG to be injected directly into natural gas
utility pipelines for distribution, or for use as a fuel to power vehicles. Leading companies from
Anheuser-Busch, L’Oreal to UPS have equally announced their commitment in addressing their
global carbon footprint by fuelling their businesses with sustainable RNG.
​
Enter AB Energy. The company already known as a groundbreaking pioneer in cogeneration systems
within the global energy market through its ECOMAX® line, is proud to announce the introduction of
its innovative BIOCH4NGE® technology to the North American market. BIOCH4NGE® is the
culmination of nearly four decades of advancements from the experience AB has acquired as an
industry leader in the cogeneration sector. BIOCH4NGE® is compact, modular, easily scalable,
versatile in application, and exceptional in its ability to upgrade and purify raw biogas into RNG at a
low cost of operation.

At its core, BIOCH4NGE® employs advanced membrane technology to separate methane from the
water, CO2, H2S, VOCs, and other impurities found in biogas. Biogas enters the first stage of the
process, where primary filtration followed by a chilled water exchanger condenses water vapor to
dehumidify the biogas. This gas is compressed, cooled by a second heat exchanger, and delivered
under strict temperature and pressure conditions to the secondary filtration stage. Here, the gas is
“stripped” of residual H2S and VOCs and sent to the heart of the system, where it passes through
AB’s proprietary membrane system separating the CO2 and CH4 molecules. The purified methane
exiting the process is now ready for beneficial re-use.
 
AB pre-assembles and tests each BIOCH4NGE® system in the company’s production facility as part
of its rigorous quality control regimen. This step dramatically reduces onsite installation and
commissioning efforts, saving clients substantial costs and avoidable start-up challenges.
“BIOCH4NGE® is the crowning achievement of our RNG production sector,” exclaims AB President
Angelo Baronchelli. “This technology represents the best of our engineering and industrial and
operational expertise, delivering a highly efficient and reliable solution to recover methane from
biogas. It’s an ideal alternative process for clients already operating an RNG facility and a strong
contender for those who are considering entering the market.”

With the ECOMAX® to complement BIOCH4NGE®, AB provides valuable resources for companies
looking to reduce their carbon footprint while increasing their reliability and resilience. ECOMAX®
high efficiencies in power generation and heat recovery help biogas facilities replace traditional
energy sources, allowing for more efficient operations and lower carbon emissions. This combination
not only benefits the environment and ensures continuous operation, but allows facilities to achieve
an even lower CI and consequently, a greater number of credits.
​
Industry leading technologies combine for a greener, renewable future - with ECOMAX® and
BIOCH4NGE® ready to energize the way for businesses, transportation, homes and more.
