A 2-year study by analysts at the U.S. Department of Energy’s National Energy Technology Laboratory (NETL), in which they synthesized new methane emission data from a series of ground-based field measurements, shows that 1.7 percent of the methane in the U.S. natural gas supply chain is emitted between extraction and delivery. Identifying the magnitude and sources of methane emissions will allow producers to prioritize opportunities to reduce emissions of the potent greenhouse gas.

Inside a new NETL laboratory, researchers are firing up a device that may one day enable unprecedented power generation performance without any moving parts. Jetting out of the nozzle of a high-velocity oxyfuel torch, a stream of plasma glows like a light-saber poised for combat. But this technology is designed to battle the low efficiencies that plague many of today’s energy conversion systems, rather than galactic evil-doers.
