HOUSTON — Under growing pressure from investors to address climate change, Exxon Mobil on Monday proposed a $100 billion project to capture the carbon emissions of big industrial plants in the Houston area and bury them deep beneath the Gulf of Mexico.
Exxon, the largest U.S. oil company, wants to create a profit-making business out of the capture of carbon emitted by petrochemical plants and other industries. But its plan would require significant government support and intervention, including the introduction of a price or tax on carbon dioxide emissions, an idea that has failed to attract enough support in Congress in the past.
The company already captures carbon, which it injects into older fields to produce more oil. Exxon now wants to use its expertise to store the carbon dioxide generated by other industries. But without a price on emitting carbon, many businesses would have little financial incentive to pay Exxon to capture and store their carbon.
The Obama administration failed to enact a cap-and-trade system, which raises costs for polluting companies by forcing them to buy tradable permits to release greenhouse gases into the atmosphere. California, the European Union and 11 states in the Northeast use versions of cap-and-trade. Other governments, including British Columbia and Britain, have imposed a per-ton tax on emissions.
embrace a price on carbon, something it has not done.
“The concept of a price on carbon is critical,” Mr. Woods said. “There has to be a way to incentivize the investment.”
Offshore storage has already gained traction in Europe, where governments have put carbon prices in place and lawmakers are more willing to spend taxpayer money to address climate change.
