Exxon lays groundwork for carbon storage project at offshore auction

HOUSTON, Nov 17 (Reuters) - Exxon Mobil Corp (XOM.N) on Wednesday offered to lease a half million acres off the Texas coast, securing space for what could become a massive project to capture and store carbon emissions.

Under pressure by investors to address climate change, Exxon in April floated an up to $100 billion industry hub to collect planet-warming emissions from Gulf Coast petrochemical plants and bury them under the Gulf of Mexico. read more

Wednesday's nearly $15 million in bids are "potentially the first time federal Gulf of Mexico acreage has been leased for purposes other than the extraction" of oil and gas, said Rystad Energy oil analyst Colin White.

The company's bidding in U.S. Department of Interior auction "takes a long-term business view," spokesperson Todd Spitler said. Exxon will evaluate the acreage seismic and subsurface geology once final awards are determined, he said.

Spitler declined to comment on the acreage's carbon capture potential. Exxon has said it will spend $15 billion on lower-carbon technologies over the next six years. It plans to disclose new details of emissions reduction and project spending in two weeks, it said in a filing.

The top U.S. oil company has been selling its Gulf of Mexico oil properties since 2018, putting investments into more lucrative fields off Guyana, Brazil and in U.S. shale.

In addition to the U.S. carbon capture hub, it has recently reached preliminary agreements with Singapore and Malaysia to explore projects. read more

Exxon snapped up 94 offshore blocks, containing 541,000 acres (219,000 hectares), the largest of any bidder and nearly a third of the tracts receiving bids. read more

"I don't see it as an oil and gas exploration move," Rystad's White said. "And it is real money on the table."

The acreage it offered to lease runs in a line off the Texas coast close to onshore infrastructure suitable for carbon capture activity, White said.

Some of the property is near Freeport, Texas, where offshore driller Talos Energy (TALO.N) on Monday proposed its own carbon capture and sequestration project with a year-end 2024 launch.
