This is an interesting project to follow. Lithium Ion batteries take most of the headlines, and most of the revenues, but hybrid systems seem to offer a great combination of technologies. Combining batteries with flywheels or supercapacitors for ultra-fast response and power, looks to be a very useful combination. Great to see this happening in Europe, and indeed the UK. Innovation shoudl always be cross borders and technology agnostic.
The system will then be installed at the University of Sheffield’s 2MW battery facility at Willenhall near Wolverhampton. The grid-connected research facility is one of the largest and fastest battery storage systems in the UK. The flywheels will be upgraded to provide 1MW of peak power and 20kWh of energy storage and used as a hybrid energy storage system with the batteries to provide frequency response services. Fast acting frequency response services, such as those provided by this hybrid solution, are a key enabler to the realisation of a high penetration of renewables – recognised by the Irish System Operators DS3 Programme for System Services. More specifically, energy storage is a key priority for the UK government, with a policy by the Department of Business, Energy and Industrial Strategy (BEIS) expected later this year.
