I’ve subscribed to the theory that “hydrogen is the fuel of the future (and always will be)” for most of my 30 years on this beat, but a confluence of recent developments suggests maybe we’re nearing a tipping point for the universe’s smallest known molecule.Accelerated development of fuel cells for use in heavy-duty trucking promises to boost infrastructure and bring the economies of scale needed to hasten light-duty fuel cell electric vehicle (FCEV) adoption. Proliferation of renewable energy is increasing demand for ways to store surplus grid power, which can be done using hydrogen, and a novel means of inexpensively producing green hydrogen is emerging.National Renewable Energy Laboratory senior research fellow and fuel cell group manager Bryan Pivovar tipped me off to this tipping point during a recent panel discussion on Autoline Detroit. His lab has teamed with five other…
