A massive underground bunker could be built under the water off the coast of Liverpool.
Large parts of the North Sea bed have been identified for offshore carbon storage, with 20 sites awarded licences. The underground sites equate to an area slightly larger than Yorkshire, some 12,000 square kilometres.
Some are located off the north east of Scotland, while others are off the shores of Liverpool, Teesside and Lincolnshire. The North Sea Transition Authority (NSTA) says the sites could one day store 10% of the UK's annual CO2 emissions.
