BAUER's Compressor Solutions for Biogas Plants
Decomposing organic material in anaerobic conditions releases methane into the atmosphere. Anaerobic fermentation is common in a landfill and open stockpiles such as manure piles. Global emissions from waste have almost doubled since 1970 and now produce 3% of anthropogenic (human origin) emissions (IPCC 2014). About half of these emissions come from the anaerobic fermentation of solid waste disposal on land.
A 2016-2018 study by NASA’s Jet Propulsion Laboratory in cooperation with the California Energy Commission utilizing airborne remote-sensing, surface-monitoring networks, and satellites over the State of California revealed more than 550 individual point sources emitting plumes of highly concentrated methane.
Ten percent of these sources, considered super-emitters, contributed the majority of the emissions detected. The team estimates that statewide, super-emitters are responsible for about a third of California’s total methane emissions.
The study revealed the top three super-emitters contributing to 93% of methane emissions to be:
- Detrimental Environment Effects:
Methane (CH4) is a major contributor to global greenhouse gas emissions which have been linked to global warming, climate change end the disruption of weather cycles. As such, methane is 25 times more detrimental to the environment than carbon dioxide (CO2) because it traps significantly more heat in the Earth’s atmosphere than CO2. Therefore, curbing methane emissions into the atmosphere is currently a high priority for methane emitters.
- Increased governmental regulation:
In October 2009, the U.S. EPA issued a rule (40 CFR Part 98) that requires the reporting of greenhouse gas (GHG) emissions from large sources and suppliers in the United States, and is intended to collect accurate and timely emissions data for future policy decisions. It is just a matter of time before emissions of greenhouse gases become more tightly regulated by both federal and state governmental agencies. The State of California, for example, has made cutting human-caused emissions a top priority.
- Increasing activist pressure directed towards municipal, state, and private industry segments:
Many public and private sectors face enormous pressure from environmental activists, the public at large as well as investors and shareholders to reduce greenhouse emissions. As a result, more and more entities whose operations generate greenhouse gases are becoming worried about their negative public image and future long-term viability.
THE SOLUTION: GENERATING BIOMETHANE AS AN ALTERNATIVE CLEAN ENERGY SOURCE
Technology has evolved, which makes capturing and processing biogas from anaerobic fermentation more economically viable. Methane emitted from decomposing waste when captured and upgraded on-site into biomethane is a valuable energy source that is significantly more environmentally friendly than diesel fuel, gasoline, or coal. Biomethane can be injected into a natural gas pipeline in exchange for revenue from the local utility, compressed into CNG for fleet fuel instead of diesel, or used as fuel to generate electricity (power co-generation). Also, the producer of biomethane can be eligible for significant tax and carbon offset credits through their respective state.
3 Sources of methane emissions from anaerobic fermentation:
- Methane Gas Emissions from Landfills
- Methane Gas Emissions from Dairy and Animal Waste
- Methane Gas Emissions from Waste Treatment Plants
For On-Site Biogas Recovery And Upgrading
Generating biogas from the methane emitted from landfills, dairies/cattle feedlots, and wastewater facilities through anaerobic fermentation not only eliminates methane emissions into the atmosphere but can also be a source of additional revenue and profit for the operator by:
- Selling the gas to utility
- Offsetting costs associated with purchasing fuel for vehicles by producing their own fuel (CNG)
- Producing their own electricity through co-generation
