in depth going deep

摘要

The use of salt caverns for CAES is expected to place it in competition with natural gas storage and carbon capture and storage, where caverns close to energy sources are required. Seamus Garvey from the University of Nottingham admits that while the use of salt caverns for CAES would be cheaper, his Energy Bags can be far more flexible in location. 'In the UK, we don't have a lot of very deep water close to shore. But interestingly, the places where that water is are the same places where the wind power is best. So there is a beautiful symmetry between where you would like to collect your wind power and where you would like to store your compressed air.' Garvey added that the US west coast, north coast of Spain, west coast of Portugal and the entire Mediterranean would be ideal sites for his Energy Bags.
