Senate Republicans have added tax breaks and other subsidies for oil drillers to the GOP tax bill making its way through Congress, including a provision that would reward companies for using an emerging greenhouse-gas-fighting technology — capturing carbon from the atmosphere — to boost production of oil by billions of barrels a year.

The Senate’s tax bill would boost baseload electricity — including nuclear and geothermal power — while slashing incentives for intermittent sources.

The Senate Finance Committee’s language would take a sledgehammer to some parts of the renewable-friendly Inflation Reduction Act while sparing others.

Senate Republicans included a tax break estimated to be worth more than $1 billion for oil and gas producers in their version of President Donald Trump’s sprawling fiscal package. The provision would allow energy companies subject to a 15% corporate alternative minimum tax to deduct certain drilling costs when calculating their taxable income.

Top Senate Republicans are running into some resistance from several key senators about the details of President Donald Trump’s “big beautiful bill,” potentially complicating plans to deliver that package by their own July 4 deadline.

Tax credits for crucial clean energy and home energy efficiency projects would be phased out, albeit less quickly.
