This is something we have been working on for some time. There is space under the North Sea where the gas was; gas that we have now extracted and burned. We can put CO2 into the space and it is just as secure as the gas was.
There are other alternatives to under sea storage, the CO2 that has been sequestered when the coal was burned can be used to make gypsum (for plaster board).
The government have left things far too late. We need new power stations, we need them now and its either this or nuclear.
We have wasted an enormous amount of money on wind farms that will not remove the need for a single conventional power station. When the wind doesn't blow conventional power stations need to be used; it is incredibly inefficient to operate them in this way. If a fraction of the wind farm investment had been directed to carbon capture we would be world leaders. We are sitting on massive coal reserves and yet face the start reality that in a few years we will have to import electricity from France.
