I realise that Soil Aquifer Treatment may be costly but it should have been utilized years ago. the Herald brought the problem to the public eye in late November 2017 when :
"GEOLOGISTS have cast doubts on plans to store greenhouse gases in a natural underground chamber deep beneath the Moray Firth, saying the area's potential has been overstated. The Captain Sandstone saline aquifer has been "widely hailed" in recent years as a solution to the dilemma of how to capture the climate-change driving carbon dioxide produced by Scotland's gas or coal-fired power stations. Previously, experts said the subterranean chasm could possibly store decades worth of industrial output and keep it from entering the atmosphere."
"Prof Underhill added: "For the past seven years, the Captain Sandstone saline aquifer, which lies buried beneath the Moray Firth, has been widely hailed as having the potential to store between 15-100 years of CO2 output from Scotland's power industry. "Our research concludes that this is the wrong exemplar to choose because the tilt of Britain leads to it rising to subcrop the seabed with few barriers to arrest gas escape and has caused fault reactivation."
