Hydrogen and the EPA Power Plant Rule

Upcoming EPA regulations are expected to allow power plants to execute a historic reduction in their emissions partly by burning hydrogen.

But many questions remain about whether hydrogen will be a viable climate tool: Few power plants today are using it at scale, and some industry observers say that unless it is produced through a “clean” process before it reaches a power plant, it may not make a significant dent in U.S. emissions overall.

Currently, most hydrogen is produced with natural gas. While that “gray” hydrogen may emit little or no carbon at a power plant when burned, giving it an advantage over coal and gas, its production is emissions-intensive.
