This startup is making manure out of other biogas power plants, and now has $62M to play with | TechCrunch
Briefly

The concept of the Reverion power plant is simple enough. It uses biogas - basically waste from agriculture such as food or manure - to generate power.
We work with hydrogen fuel cells, and created a new system architecture around those. And the process design is very different to normal biogas power plants.
It becomes carbon negative, because we have integrated CO2 separation. The unit itself doesn't produce gases like an engine, other than a CO2 stream that can be liquified and made transportable.
