An example is a promising clean hydrogen production project from Nebraska-based Monolith, which got a serious boost recently when the US Department of Energy (DOE) said it will conditionally guarantee the project a loan guarantee of $1.04 billion. The company uses a process known as methane pyrolysis that, when powered by renewable energy, produces zero-emissions hydrogen and a solid-state carbon called carbon black, a material with a variety of industrial uses.
