EPA issues final actions to cut methane emissions from municipal solid waste landfills
July 17, 2016
The US Environmental Protection Agency (EPA) issued final New Source Performance Standards (NSPS) to reduce emissions of methane-rich landfill gas from new, modified and reconstructed municipal solid waste (MSW) landfills, updating standards that were issued in 1996.
In a separate action, EPA also issued revised guidelines for reducing emissions from existing MSW landfills, updating the previous Emissions Guidelines, which also were issued in 1996.
FuelCell Energy pathway for hydrogen from digester gas has negative carbon intensity for CA LCFS
December 23, 2015
Connecticut-based FuelCell Energy (FCE) has applied for a prospective pathway for California’s Low Carbon Fuel Standard (LCFS) for the production of hydrogen fuel produced from biogas derived from the mesophilic anaerobic digestion of wastewater sludge at a publicly owned treatment works (POTW).
The biogas is cleaned, then internally reformed in an integrated hydrogen energy system (Tri-Gen DFC) that produces hydrogen fuel for transportation; electric power for plant operations and export; as well as thermal energy for plant use. Once the internal energy demands of the pathway have been met, any energy not utilized for process is considered to be surplus to the system boundary and is credited to the FCE pathway.
