Engineer pours cold water on battery and hydrogen technologies

Global Warming Policy Foundation – 07/02/19

A new briefing paper from the Global Warming Policy Foundation (GWPF) dismisses the idea that grid-scale electricity storage can help bring about a UK renewables revolution.

According to the paper’s author, Professor Jack Ponton, an emeritus professor of engineering from the University of Edinburgh, current approaches are either technically inadequate or commercially unviable.

Many commentators have suggested that intermittent power from wind turbines could simply be balanced with batteries or pumped hydro storage, but as Professor Ponton explains, this approach is unlikely to be viable.

“You need storage to deal with lulls in wind generation that can last for several days, so the amount required would be impracticably large. And because this would only be required intermittently, its capital cost could probably never be recovered”.

Professor Ponton also thinks that another potential saviour of the renewables revolution – hydrogen storage – has been unjustifiably hyped:

“A major problem with hydrogen is its low volumetric energy density. The only practical way of storing the large volumes required would be in underground caverns or depleted gasfields. We are already short of this type of storage for winter supplies of natural gas.”

Professor Ponton concludes that a lack of suitable storage technologies means that intermittent renewables cannot replace dispatchable coal, gas and nuclear power and so a sensible energy policy cannot be based on them.

“Wind and solar power are not available on demand and there are no technologies to make them so. Refusing to face these inconvenient facts poses a serious threat to our energy security”.

  1. “Global Warming Policy Foundation”…Headed by Nigel Lawson(Ex Minister in Thatcher’s government) and Benny(Benjamin?)Peiser. A “Charitable Foundation”…does that mean Donations are Tax Deductable? The Donors have NOT been revealed publicly, so, I imagine its just another “Think Tank” run by very influential people for Political purposes, while the people pay for it(in uncollected taxes) from this “Charity”…….
    There’s no doubt about it, Charitable Foundations don’t actually ‘give’ anything to anyone…They just get Tax Benefits for what ever “barrow” they are pushing.

    • By that standard we would have to ignore any and all science and academic output which is all the result of some such institution or organization.

      There have to be more than one side engaged to have any debate on an issue.

      Either the “green deal” is workable or? We should just go on faith?

      In this case, the abundantly funded and promoted AGW fearmongers’ “solutions” fall well short, in fact fail entirely.

      Who will be left to do without power?
