Old UK oilwells could be turned into CO2 burial test sites

Exclusive: Consortium of energy firms and universities says underground storage of hydrogen can also be investigatedExhausted oil and gas wells would be turned into the UK's first deep test sites for burying carbon dioxide next year, under plans from a consortium of universities and energy companies.There are hundreds of active onshore oil and gas wells in the UK. But as they come to the end of their lives, some need to be redeployed for trials of pumping CO2 underground and monitoring it to ensure it does not escape, the group says. The test wells could also be used to assess how hydrogen can be stored underground. Continue reading...
