Mayflower Clean Energy Center
On a spit of land at the mouth of the Taunton River in southern Massachusetts you'll see this tower. It's the Mayflower Clean Energy Center built by GreatPoint Energy to turn coal--the dirtiest fossil fuel--into cleaner-burning natural gas.
The 200-foot tower contains a reactor--essentially a long metal tube under high heat and pressure--where coal is mixed with steam and a proprietary catalyst. Inside the hydromethanization reactor, that mixture turns into gases and the residue is collected through that white silo on the right. The company is separating methane--the primary component of natural gas--and carbon dioxide, which the company plans to store underground.
