The investment program includes 18 deals, including a lucrative contract to invest in wind farms through ScottishPower’s East Anglia hub.

The project, which was first announced in 2019, could power more than 2.7 million homes once operational.

Appearing on stage at today’s investment summit, the Prime Minister and Mr Gates announced a “revolutionary partnership” between the Bill and Melinda Gates Foundation and the UK government.

The partnership will see £ 800million in joint funding in green technology.

The prime minister said the deal will support direct capture into the air, long-term battery life, zero jet and green hydrogen technology.

He said: “I think these are all technologies that have huge potential but are currently underinvested compared to others.”

Mr Gates also took the opportunity to welcome the progress the UK has already made in tackling the climate crisis.

He said the UK had made “huge strides” in reducing carbon emissions and introduced big policies to support science.
