Start-Ups to Mine Methane Troves...

摘要

Existing gas-to-liquids methods usually oxidize methane to syngas, a mixture of carbon monoxide and hydrogen, and then convert the syngas to methanol or other hydrocarbons. The approach works but is challenged by both high capital costs and low conversion efficiencies, the Department of Energy (DOE) said earlier this year. Calysta Energy, based in Menlo Park, CA., says it has a lower-capital biological conversion method that operates near room temperature and pressure.
