Power-to-X

To reduce greenhouse gas emissions that were contributing to climate change, the world needs to transition from fossil fuels to renewable energy sources. Power-to-X (PtX) refers to an array of processes that convert electricity (power) to various gaseous and liquid fuels (X). PtX is widely viewed as essential to accelerating the deployment of renewable energy. This note focuses on five central PtX fuels: hydrogen, ammonia, syngas, methanol, and methane.
