Oil companies are also under growing pressure to reduce the carbon content of the energy products they sell. They are investing in wind and solar power, which have proved to work, as well as in technologies, like carbon capture, that fit with their expertise and may not pay off until well into the next decade, if ever.

thriving offshore wind-turbine industry.

Late last year, Mr. Johnson’s government also said it would seed carbon capture investments with a fund of up to £1 billion. The government has proposed two carbon capture “clusters” like Teesside by the mid-2020s and two more by 2030. All the candidates are northern industrial areas, the region that helped assure the Conservative Party’s victory last election.

The investments would bolster Mr. Johnson’s pledge that Britain’s carbon emissions will reach net zero by 2050. The Climate Change Committee, Britain’s environmental watchdog, said in a recent study that carbon capture would be “essential to achieving” that goal at lowest cost.

If BP can put together a package including government support that provides sufficient profits for the company, the power plant could begin operating in around five years.

Mr. Lane’s goal, he said, is to create a regulatory and technology model that can be used many times, cutting costs like the wind and solar power industries.

“These things can be done, and they can be done repeatedly in many parts of the world,” he said. “But you have to start.”
