Highview’s CryoEnergy System Efficiently Stores Energy With Liquified Air

When all the criteria for energy storage is taken into consideration, the use of batteries is inferior to CES. While high-efficiency batteries can yield 1 kW of power, they cost about US $4,000 which is 4 times the cost required by CES to produce the same power

A pilot project, fully integrated into the UK’s national grid, is currently in operation and is being supported by the Department of Energy & Climate Change and UK-based utility SSE (Scottish & Southern Energy). Highview plans to have a 3.5 megawatt (MW) commercial-scale plant operational by 2012, with the aim of increasing capacity to 10MW by 2014.

In the race to find the innovative energy storage solution that can take our renewable energy ambitions to the next level, CES provides the most efficient, economic and environmentally-friendly answer. So far.

    The comment by Chris offspring, above makes a good point. Can some use be found for the waste heat produced when cooling the air to liquify it….?

    However I do have one quibble with the article. It points out that this is a better option than batteries but goes on to say that it is the “most efficient” As the Higview material makes clear, currently the most efficient way of storing electricity on a large scale is pumped storage. The problem is that you need a suitable site for pumped storage, and these are a matter of the right geography so while further pumped storage is being developed in Scotland the potential for more of it is limited. Hence the need to look for other methods.

    I’m still thinking about this:
    while it sounds nice to have “cold air”, this air would be so cold, it would instantly freeze you. So powering a turbine with it would mean you’d have to pre-heat said turbine. That said, i’m wondering why this article doesn’t talk about the heat, that is produced when you cool down the air to cryogen. (And the cooling is definitly accomplished with the help of a heat exchanger)
    Storing the heat and then reusing it to keep the turbine from becoming a very giant paper weight, sounds like a good plan to me.
    And while we are at it: why use waste heat? It’s an option but not the only possibility. Setting up such cryoenergy systems near server farms or internet exchange points would wastly improve the efficiency of either the cryoenergy system or the server farm / IXP (or in general: everything that needs cooling, which right now is accomplished by normal electricity-using air-conditioners)
    Or look at big cities: Skyscrapers look nice with their all-glass covers, but need a lot of cooling in summer. Set up a cryoenergy system in each skyscapers basement and you can lower their energy consumption by quite a bit.
