World First As Liquid-Air Energy Storage Makes Commercial Debut Near Manchester United Ground

The title of this post is the same as that of this article on Recharge.

I can add some extra information starting with this picture from Highview Power, which shows a visualisation of the CRYObattery.

Unfortunately, it doesn’t show any objects, which can give an idea of the size of the plant.

Levelised Cost Of Energy

LCOE or Levelised Cost Of Energy will be a term, that will be increasing used, when electricity generation is discussed. This is Wikipedia’s definition of the term.

The levelized cost of energy (LCOE), or levelized cost of electricity, is a measure of the average net present cost of electricity generation for a generating plant over its lifetime. The LCOE is calculated as the ratio between all the discounted costs over the lifetime of an electricity generating plant divided by a discounted sum of the actual energy amounts delivered. The LCOE is used to compare different methods of electricity generation on a consistent basis. The LCOE “represents the average revenue per unit of electricity generated that would be required to recover the costs of building and operating a generating plant during an assumed financial life and duty cycle.” Inputs to LCOE are chosen by the estimator. They can include cost of capital, “fuel costs, fixed and variable operations and maintenance costs, financing costs, and an assumed utilization rate.

Make sure, when comparing different LCOE values for different methods of energy generation, that the same method was used to calculate LCOE.

Comparative Costs

The article quotes the following costs on an LCOS or Levelised Cost Of Storage basis, which enables comparison to be made according to the same rules.

  • A 200 MW/2 GWh CRYObattery will cost £110/MWh
  • Pumped storage/hydro will cost £123-150/MWh
  • Lithium-ion will cost £231-470/MWh

I have converted some from dollars.

I do think that  a 2 GWh CRYObattery could be very good value!

Income

The article says this about how the CRYObattery will earn us keep.

Income will come through grid balancing, ancillary services such as frequency response and voltage support, and arbitrage — buying electricity when wholesale prices are low and selling it when prices are high.

I suspect that if a company like Carlton Highview Power had several large batteries around the country, this would be an advantage to the company.
