De-Hyping Hydrogen

Climate One

About
For decades, hydrogen has held promise as a revolutionary tool in the clean energy transition. It can be a fuel and energy carrier, and when made with renewable energy and burned in a fuel cell, its only byproduct is water. President Biden’s administration invested billions into proposed clean hydrogen hubs. But as we’ve seen dramatic technological innovations and drastic price drops for solar and wind, lithium-ion batteries, and heat pumps — hydrogen may have gone from tomorrow’s technology to yesterday’s solution.

Experts say the best uses of green hydrogen come down to decarbonizing certain industries, like steel manufacturing and fertilizer. So where does hydrogen fit in the modern energy mix?
