October 11 (Renewables Now) - Bloom Energy Corp (NYSE:BE), a maker of solid oxide fuel cells (SOFC), and dairy digesters developer California Bioenergy LLC (CalBio) have combined their technologies to deliver a commercial solution for converting cow manure into renewable power for electric vehicles (EVs).
CalBio designs and develops digesters that capture biogas from methane-laden dairy manure through anaerobic digestion while separating the hydrogen sulfide (H2S). This technology is then paired with Bloom’s SOFC power generators, called Bloom Energy Servers, that use biogas as fuel to produce renewable power without combustion.
All the electricity produced in the process can be sent to the grid to feed EV charging stations across California, Bloom said. In addition to environmental benefits, the new technology will also support local job creation and generate income for dairy farmers.
While EVs are touted as clean vehicles, their charging in California may not be clean at all, according to Bloom. The company says that the US state mostly relies on natural gas-sourced electricity or imported coal-based power for night-time EV charging.
The partners say there is an estimated 320 MW of economically viable dairy biogas in California.
