GS Yuasa, a global leader in battery technology, has played a pivotal role in powering the future of sustainable energy at a unique multi-technology energy centre in Wales. Unveiled by Infinite Renewables, the energy centre supplies power for the UK Royal Mint at Llantrisant. 

At the heart of The Royal Mint Energy Centre is GS Yuasa’s state-of-the-art dual-chemistry energy storage system (ESS). This system uniquely combines 1,120 50Ah LIM50EL lithium-ion cells known for their rapid discharge and quick response capabilities, with 240 1000Ah SLR1000 lead-acid cells, which are prized for their longevity and robustness in prolonged energy provision.

Housed in two separate containers, this advanced setup is meticulously designed to ensure optimal energy distribution: the lithium-ion batteries are predominantly utilised until they are discharged to 20%, at which point the lead-acid batteries take the lead, with their current rising swiftly to complement and support the energy demands. This blend of the two chemistries represents the peak of current battery technology, harnessing the strengths of both types to deliver an unparalleled power solution for power shifting and energy distribution.

The world’s first EES of this type was installed at the Japanese-based global battery manufacturer’s manufacturing plant situated a stone's throw away in Ebbw Vale, where a combination of wind turbines, 3,000 solar panels and battery storage provide reliable and cost-efficient green power to the factory.

The Energy Centre, which comprises of a 2 MW solar farm, two wind turbines and a combined heat and power (CHP) unit along with GS Yuasa's ESS, has been expertly designed to provide approximately 75% of The Royal Mint's energy needs, and holds the potential to supply a microgrid connected to adjacent businesses.
