UNIVERSITY PARK, Pa., May 12 -- Pennsylvania State University issued the following news release:

UNIVERSITY PARK, Pa. - An international team, led by Penn State's Institute of Energy and the Environment Director Bruce Logan, has developed a new reactor design that efficiently converts carbon dioxide and renewable electricity into methane - the primary component of natural gas - while scaling the system up by roughly an order of magnitude without sacrificing performance.

The study, published in Water Research, demonstrated that microbial electrosynthesis systems can be expanded beyond laboratory-scale devices while maintaining high energy efficiency and methane production rates.
