DENVER — Hydrogen's promise as a climate-friendly alternative to fossil fuels has been envisioned for decades. Besides a few fits and starts, it's been an elusive promise.
Whether hydrogen can fulfill a more prominent role in reducing emissions remains a key question as government and industry leaders across the globe seek to combat climate change.
"We admire hydrogen every decade or so, and the buzz subsides," said Doreen Harris, CEO of the New York State Energy Research and Development Authority. "But I believe we're at an inflection point where that is no longer going to be the case."
Harris spoke last week at the ARPA-E Energy Innovation Summit, where figuring out how to advance hydrogen's viability as a widespread energy source was a key theme.
