Owners of the world’s largest carbon capture facility plan to restore operations at the $1 billion plant three years after it shut down, providing a test case for a nascent industry that experts believe is essential in achieving climate goals.

JX Nippon aims to restart the Petra Nova facility in Texas after NRG Energy finishes repairs on the coal-fired power unit to which it is connected, the company said in an emailed response to questions. NRG said it’s scheduled to complete the work in June.

The resumption would mark a significant step forward for U.S. carbon capture, providing a new lease of life for a project that critics saw as one of the industry’s highest-profile failures. U.S. President Joe Biden's Inflation Reduction Act provides major tax incentives to boost development of the technology that would scrub emissions from burning fossil fuels. Some environmentalists contend that even if it works, carbon capture extends the life of oil and gas extraction. Supporters say there’s no other viable option to decarbonizing high-polluting industries.
