Is the world ready for organic flow batteries using extracts from rhubarb? PEI reports on some new electricity storage ideas hoping to save renewable energy from ultimate failure. ‘Holy Grail’ or wild goose chase – time will tell.

The US energy secretary, Ernest Moniz, believes the advances being made in storage technology means that the country will be completely decarbonised by the 2050s.

A global race, seen initially in Europe and the US is leading to a rapid acceleration in innovation that may dispense with the need for nuclear and thermal power by that time according to the technology’s backers, as the Achilles heel of intermittency will no longer impact on the overall effectiveness of renewables.

Nothing about costs, but let’s see how this demonstration project goes. The technology has already been tried in cars.

Europe’s first flywheel hybrid energy storage plant has been officially launched in Ireland, reports PEI.

The plant in Rhode, County Offaly, is owned and operated by Irish energy company Schwungrad Energie and is expected to enter a test operational phase in February.

Some might query whether 5 megawatts is ‘giant’ in terms of national electricity demand, and the usual claims that battery costs are going to drop like a stone are made, but nevertheless this attempt at an energy storage system is happening, as edie.net reports.

German energy company E.ON has started constructing the world’s first modular large-scale battery in the German town of Aachen.

The modular aspect of the design means that various battery technologies can be ‘plugged in’ to the system – a world-first for a battery of this size.

Claims of up to 70% efficiency have been made for converting ‘wrong time’ electricity produced by intermittent generators such as wind turbines to ‘right time’ electricity supplied onto the grid. The proposed storage medium is liquid air (with co2 and water vapour first removed. This -190C medium is used to drive a piston engine without combustion, and waste heat is re-used.
