This technology enabled to directly prepare methane with up to 1,000 times or higher concentration from 100 ppm CO 2, which is a lower concentration than atmospheric CO 2. Since the atmosphere ...

So there’s no immediate performance improvement or volumetric disadvantage, like you would see with hydrogen fuel. Instead it is a series of small factors that all add up to a meaningful design ...

The sediment was saturated with methane and contained nitrate at a concentration of 1 mM. The culture obtained grew on methane and nitrate (or nitrite) as the sole energy sources, with an ...
