Swiss Zurich Energy Storage Vanadium Battery

Which energy storage projects have been commissioned in Switzerland?

Axpo commissioned its BESS in February this year while utility Thurplus commissioned a 3MW system in September last year. But Switzerland was the location for one of the largest energy storage projects commissioned in recent years, a 20GWh pumped hydro energy storage (PHES) unit which started operations in June 2022 in the Canton of Valais.

Are lithium-ion pumped hydro energy storage and flow batteries sustainable?

The sustainability of lithium-ion, lead–acid compressed air, pumped hydro energy storage, and flow batteries concentration gradient were investigated by implementing a multi-dimensional LCA. The analysis concluded that the lead–acid battery resulted in the most severe damage to ecosystem diversity and human health.

Is MW storage the country's largest battery storage project?

MW Storage is a developer of BESS projects which is also active in the German market, with a 100MW/200MWh project underway that it claimed is the country’s largest. The inauguration ceremony for the BESS project. Image: EWS AG. EWS AG and MW Storage have expanded a battery storage project in Switzerland to 28MW, making it the country's largest.

Is Bess being monetised in the Swiss electricity market?

It is being monetised in the Swiss electricity market by both CKW, part of Axpo, and utility Alpiq, the announcement said. The BESS is part of a network of power plants, consumers and batteries, it added. The large-scale BESS market in Switzerland has been relatively quiet with renewable penetration on the country’s grid still relatively low.

Does vanadium need a new redox-active material?

Vanadium is a critical mineral that is mainly imported from China and Russia, so it comes with many of the same cost and supply chain challenges as lithium-ion. In fact, the DOE report referenced earlier stated that new redox-active materials – not vanadium – are needed to achieve an LCOS below lithium-ion.
