“It’s going to make a massive difference to the cost of energy for consumers, because, of course, our homegrown sovereign renewables are much, much cheaper than any other form of generation,” he says.
No, they’re not.
Highview Power, based in London, believes it has a solution: use cryogenic liquid air to store the electricity until it is needed.
The pioneering technology works by compressing air into a liquid and then cooling it to almost minus 200°C.
The liquid air is stored in an insulated tank at low pressure, which functions as the energy store. When power is needed, liquid air is drawn from the tank and pumped to high pressure.
Stored heat from the air liquefier is applied to the liquid air via heat exchangers and an intermediate heat transfer fluid. This produces a high pressure gas, which is then used to drive a turbine and generate electricity.
Chief executive Rupert Pearce says the loss of energy during the process is around 50pc, but much of the waste is through heat which can be recovered, taking its potential to about 70pc.
The thing we desire is power we can use – power when we want it. If renewables require all this sort of gubbins to achieve that then they’re not much, much, cheaper, are they?
The only important price is, after all, the price of the power we can use, when we want to use power.
