A flood of investments and energy industry pledges made 2020 a breakout year for low-carbon hydrogen. But 2021 may be when the hype gives way to hard questions, E&E News reported.

"The idea of hydrogen has been around for a long time," said Mona Dajani, who leads Pillsbury’s Hydrogen practice. "But its momentum has never been stronger."

Wealthy European and Asian countries have set new goals for hydrogen development as part of plans to rebuild after the coronavirus pandemic, Dajani noted. And as pressure for climate action builds, some oil and gas majors are turning to hydrogen to hedge risks.

Big energy companies "are willing to invest in projects that may not pencil out right now because they know, technology-wise, they have to get into it," said Dajani. "If they don't, they're going to lose out."
