Transporting methane from gas wellheads to market provides multiple opportunities for this greenhouse gas to leak into the atmosphere. 007_straightNow, an international team of researchers has taken the first step in converting methane directly to electricity using bacteria, in a way that could be done near the drilling sites.  “Currently, we have to ship methane via pipelines,” said Thomas K. Wood, holder of the biotechnology endowed chair and professor of chemical engineering, Penn State. “When you ship methane, you release a greenhouse gas. We can’t eliminate all the leakage, but we could cut it in half if we didn’t ship it via pipe long distances.”  The researchers’ goal is to use microbial fuel cells to convert methane into electricity near the wellheads, eliminating long-distance transport. That goal is still far in the future, but they now have created a bacteria-powered fuel cell that can convert the methane into small amounts of electricity.
