Chevron plans to spend about $2.5-billion building up its hydrogen business this decade as the oil major accelerates investment in low-carbon technologies.

Chevron will develop both green and blue hydrogen, said Austin Knight, vice president of hydrogen at the company’s New Energies unit. The former is made with renewable energy, while the latter is created from natural gas equipped with technology to capture emissions.

The American energy giant announced last fall it was allocating $10-billion toward developing renewable fuels, hydrogen and carbon capture through 2028, but it didn’t specify how that money would be split among various technologies.

“What you see right now is a shift to broader energy solutions with hydrogen and moving more into clean hydrogen,” Knight said at a conference in London hosted by the Financial Times. “We want to be a part of that ramp-up.”

Hydrogen is poised to be a key part of global efforts to reduce greenhouse-gas emissions. The clean-burning fuel can replace natural gas or coal in heavy industrial processes that otherwise are difficult to decarbonize. US President Joe Biden’s infrastructure plan included funding to build at least four hydrogen hubs.

“We should set the rules very clearly around what low carbon actually means, and then let the markets work to deliver real carbon reduction,” Knight said.

At the same time, Chevron is among the oil refiners being pressured by the Biden administration to improve capacity as the soaring price of gasoline at U.S. pumps feeds record inflation -- and unprecedented profit margins. The San Ramon, California-based company’s shares have risen more than 30% so far this year.

Hydrogen made from natural gas with carbon capture can be built at larger scale today than the renewable power-based alternative, Knight said. Still, European oil majors such as France’s TotalEnergies and the UK’s BP are targeting multibillion-dollar investments in green hydrogen projects.
