In what could prove a milestone for an industry that hopes to help address climate change, the Silicon Valley company Ohmium announced Wednesday it has raised $250 million to increase production of machines that can make clean hydrogen and displace fossil fuels.

Some climate experts say burning hydrogen can substitute for burning coal, oil or gas, for example in making steel or cement — without contributing to climate change. That's been largely theoretical, but real world examples are now growing.
