Warning, risk of electric shock

[Re: It’s about time for Rishi Sunak to make his mind up on on a road tax, Nov 19]

In the same way that government’s previously promoted diesel power as the solution to saving energy and the planet, electric vehicles are a similar red-herring.

Batteries are not going to save us, as the practicalities of producing, charging and disposing of huge batteries are simply not sustainable.

All the batteries on Earth only store just ten minutes of the world’s electricity needs.

One kilogram of compressed hydrogen has 600 times the energy of a one kilogram of lithium ion battery.

Green Hydrogen, produced by off-peak, curtailed renewable electricity and Rolls Royce-type small modular nuclear reactors, supplying hydrogen fuel cell powered cars, plans and ships is the long term sustainable answer.

Any chance of a stable government? Small businesses need some stability but Lord Frost’s posturing is seriously unsettling.

Frost, as a peer, is an unelected member of the current Cabinet and yet it is he who may walk us into a trade war with the EU.

 He is not accountable to a constituency or an industry and I’m not sure that even the whisky industry would now welcome a trade war.
