A redox flow battery for MW-sized solar-plus-storage |
Matt Harper, chief commercial officer of newly-merged British-Canadian vanadium redox flow battery business Invinity Energy Systems has spoken to pv magazine about the VS3-022 Battery Unit it is marketing for grid scale solar-plus-storage projects and why it may be a better bet than lithium-ion.
With London-based private company redT energy and transatlantic peer Avalon Battery Corp last month announcing a £57.7 million merger ($71.6 million) to form vanadium redox flow battery manufacturer Invinity Energy Systems, Matt Harper, chief commercial officer of the new entity, has spoken to pv magazine about the VS3-022 Battery Unit Invinity is offering for grid scale solar-plus-storage projects.
The Invinity representative said the company, which was formed via a reverse takeover and is listed on the London Stock Exchange, has more than 40 operating flow battery storage projects. "The majority of our fleet is in service alongside megawatt-scale PV projects," said Harper. "This includes a 1 MWh project in Iowa, USA, which is supporting a 1 MW behind-the-meter PV array, and a 2 MWh energy storage system in Qinghai province, China, that is installed as part of a 1.6 GW solar park."
With Invinity targeting the solar-plus-storage market, its typical customer wants at least 1 MW of solar-plus-storage capacity, according to Harper.
The VS3-022 battery has a reported storage capacity of 220 kWh and continuous maximum DC power of 76 kW. Annual degradation of storage capacity is indicated at less than 0.5% and energy efficiency annual degradation is less than 0.1%, according to the manufacturer. The 6.058 x 2.438 x 2.4m battery has an ambient operating temperature range of –5 to 45 degrees Celsius and a lifetime of 25 years and 20,000 cycles, according to Invinity, although Harper claimed the product does not degrade at all with use.
