Climate Change: Net Zero Strategy

Lord Wigley Excerpts

Wednesday 3rd May 2023 Lords Chamber

[Lord Callanan (Con)]

The sixth carbon budget goes through to 2038. We have set out policies to meet— I think—about 97% of the targets under that and we have a number of other policies that are so far unquantified. In essence, the noble Lord is right, of course. As we make faster progress—and we are making very swift progress—the targets become more difficult to meet: but I am confident that we can do so.

[Lord Wigley (PC)]

My Lords, is the Minister aware that, in order to get the maximum benefit at the right time from wind power and other power supplies that come at inappropriate times, there is a real case for additional pumped-storage capacity? Will he do what he can to speed up the establishment of a clear financial base? At present that is holding back some very valuable projects.

[Lord Callanan (Con)]

The noble Lord makes an important point. As we have more and more intermittent renewables coming on to the grid, we will need to balance that out with increased storage capacity, which may be pumped storage: of course, there is an excellent example in Wales in the Dinorwig plant, but there are examples in Scotland as well. As well as storage mechanisms such as pumped storage and battery storage, the potential of long-term hydrogen storage in salt caverns is extremely exciting.
