Science can now turn thin air into biomass – or, more specifically, turn greenhouse gases such as carbon dioxide (CO2) and methane (CH4) which are emitted as waste products of current energy production activities into biomass. This paper describes a process that captures methane from natural gas and biogas and uses photosynthesis to convert it into biomass feedstock. The energy-rich carbon is not dispersed into the atmosphere as a greenhouse gas, but converted to useful products. Read more here.
