Why Is There So Much Hype About Hydrogen

Renewable energy sources can help lower emissions from electricity generation, but they have limitations when it comes to other sectors. Wind and solar, for example, can’t help much with the decarbonization of energy-intensive industries such as steel-making, marine fuels, or heavy-duty transportation.

   So industries and governments are looking at alternative fuels that could make those hard-to-decarbonize sectors less polluting as the world grapples with reducing greenhouse gas emissions. In recent years, hydrogen has gained a…
