Invinity Energy Systems PLC (AIM:IES) shares jumped 11% after the utility-grade energy storage manufacturer delivered, installed and energised a battery system in a hydrogen test facility in the Orkney Islands.
The 1.8 megawatt (MW) battery was “successfully energised” at the European Marine Energy Centre (EMEC) hydrogen R&D facility on the island of Eday.
The project comprimises 48 Invinity VS3 battery modules made at the company's West Lothian facility, with a combined capacity equivalent to the daily energy consumption of over 210 UK households.
Integrating the batteries with tidal generation is designed to optimise green hydrogen production at EMEC's hydrogen production plant.
Although tidal energy generation is predictable it is variable due to the two low tides occurring each day, so the battery is designed to smooth the power from tidal generation by storing it during high power periods and releasing during low power periods.
This should ensure that EMEC's 670 kW hydrogen electrolyser has a stable, renewable power supply, allowing the continuous production of green hydrogen.
EMEC's tidal power system, which uses technology from Scotland-based Orbital Marine Power Ltd and Tocardo, a Dutch tidal power company, is in its final commissioning phase as it integrates its tidal turbines and electrolyser.
Invinity shares rose 11% to 51.1p in early trading.
