    Storing wind power. Hydrogen generation

    This adds in another layer of complexity and conversion loses but I believe it has a place especially in small systems

    Working on Unst in the shetlands

    They have wind turbines, hydrogen generator and a fuel cell. So they have leccy the whole time. Tehy also run a car off it

    Im up in Scotland and see new wind farms popping up all the time. Its windy enough up here without more wind being generated by these things!

    At no point did I say that Scotland’s hydro is untapped. I said it is used “on tap” to fulfill peaks in demand.

    Aye sorry, I was half-cut when I typed the reply!

    However, it’s unlikely we’ll see any more large projects due to the perceived/actual environmental impacts of building dams etc. Microgeneration is much more likely to be a better option, with the Feed-in Tariff.

    In terms of the economics of wind power, on-shore is expected to be comparable to CCS (once commercialised), while off-shore will remain significantly more expensive, mostly due to the very high initial capital costs. However CCS projects are able to provide the base-load that wind can’t, and so are a better option anyway at least in that regard.
