A set of technologies that is expected to have its first results four years from now is designed to resolve one of the world’s greatest oil and gas exploration challenges today: carbon dioxide (CO2) and methane (CH4) emission in the atmosphere.
The innovation, the result of a patent deposited in 2018, consists of injecting the CO2 and CH4 that comes from wells during oil extraction into salt caverns as a way to reduce the amount of carbon gas in the emissions.
The first “pilot cavern” may be ready by 2022 and is the result of studies carried out at the Research Center for Gas Innovation (RCGI), established by FAPESP and Shell, headquartered at the Polytechnic School of the University of São Paulo (Poli-USP). The RCGI is one of the Engineering Research Centers (ERC) funded by FAPESP in partnership with companies.
“This is a concept known as Carbon Capture Storage (CCS). In this case, the CO2 is stored in large caverns in the salt layer itself. This is perhaps one of the best ways to obtain clean energy from a fossil fuel during the production process,” said Julio Meneghini (photo), a professor at Poli-USP and RCGI coordinator.
