The prime minister is expected to announce millions of pounds of funding for a carbon capture project during a visit to the north east of Scotland.
Rishi Sunak will emphasise the role the region will play in the UK’s wider energy security plans as he meets industry figures this week.
The UK government said Scottish schemes will help it grow the economy and meet its 2050 net zero commitment.
But opponents say the Conservatives are “doubling down” on fossil fuels.
It comes as the party faces internal divisions over its green policies – such as the review over low-traffic neighbourhoods in England – with some MPs calling for a rethink.
Mr Sunak will confirm funding for the Acorn Project in St Fergus, Aberdeenshire, according to The Sunday Times.
The newspaper said the project, a joint venture between Shell UK and other companies, could see up to 21,000 jobs created.
If given the go ahead, it would become Scotland’s first carbon capture and storage facility, which would see harmful greenhouse gas emissions piped under the North Sea.
This would prevent the release of carbon dioxide into the atmosphere, by capturing it at the point where the fossil fuel is being burnt.
The UK government said its “decisive action” would provide highly-skilled jobs for young people in the region.
It added this package would “defend the public” against the disruption of global energy supplies by Russian President Vladimir Putin.
However climate campaigners said carbon capture was a greenwashing tactic design to keep the fossil fuel industry in business.
March Church, of Friends of the Earth Scotland, said: “Funding for the Acorn project would be yet another massive public subsidy to oil companies who have been making billions in profits, while ordinary people are struggling to pay the bills.
“Instead of handing more money to polluters, it is time to redirect that investment to climate solutions that we know can deliver emissions cuts and improve peoples’ lives today – such as improving public transport and insulating people’s homes to help with energy bills.”
