MW Energy Storage

6th February 2012

ITM Power the energy storage and clean fuel company, is pleased to announce that it will be launching its new high pressure and high volume stack designs that form the basis of its Megawatt Scale energy storage plant at the Hannover Messe on 23-27th April and All-Energy in Aberdeen on 23-24th May.

The hydrogen production plant is packaged in a single 20ft standard ISO container and is a 1MW load that can be demand side managed by power companies with a response time of one second for both turn on and turn off. The hydrogen produced can be used for both vehicle refuelling and direct injection of hydrogen into the gas grid. Injecting hydrogen into the gas grid is a simple and pragmatic form of energy storage that also de-carbonises the gas grid.

The new electrolyser stack is self-pressurising to 80bar which means it can be used to inject hydrogen directly into the high or low pressure gas grid without the need for additional compression plant. If the hydrogen production unit is used for vehicle refuelling, the amount of energy required for compression is reduced. If 350bar refuelling is being used then the high pressure electrolysis removes the need for one stage of mechanical compression which reduces cost.

The 1MW container produces approximately 400kg/day of hydrogen if run continuously. The design is a modular system which can be used to build larger energy storage facilities. ITM Power now has a portfolio of modular refuelling products in the range from 5kg/day to 400kg/day.

Commenting for ITM Power Dr Graham Cooley said “Megawatt scale energy storage is now a vital plant component in the power industry to balance supply and demand and this product is ITM’s first offering to the sector. In most countries in Europe and indeed the rest of the world the penetration of intermittent renewable power has reached the level where constraint payments are now standard and wind curtailment is in daily operation. The need for Megawatt scale energy storage is here today and hydrogen via electrolysis is easily deployed at this scale.”
