Core Viewpoint - Voltstorage, a German redox flow battery company, is set to cease operations due to unsuccessful fundraising efforts, aiming to avoid bankruptcy while still having funds available to settle company obligations [2][2][2] Company Overview - VoltStorage was founded in 2016 in Munich, Germany, by Bitner, Michael Peither, and Felix Kiefl, and was the first company to utilize redox flow battery technology as a home storage solution [2][2] - In 2018, VoltStorage launched its first all-vanadium redox flow battery (VRF) energy storage system, known as VoltStorage SMART, which does not require rare materials, is fully recyclable, and is considered a reliable and durable alternative to lithium-ion batteries [2][2][2] Reasons for Closure - The decision to halt operations is attributed to a combination of market adversities, investment cycles, and strategic decisions, as stated by Voltstorage's Chief Technology Officer, John Alper [2][2][2]

Core Viewpoint - Flexbase Group is developing a significant energy storage project in Switzerland, which is expected to be one of the largest flow battery storage projects in Europe, integrating grid storage, data centers, and regional heating networks [1][2]. Group 1: Project Overview - The project involves the construction of an 800 MW/1.6 GWh redox flow battery storage facility in Laufenburg, Switzerland, with plans for commercial operation by summer 2028 [1][2]. - The facility will occupy 20,000 square meters and is strategically located at a grid interconnection hub that connects Switzerland, Germany, and France, featuring 41 cross-border lines [1][2]. Group 2: Investment and Capacity - Although the specific investment amount is undisclosed, reports suggest it is a "multi-billion euro project" [2]. - The 1.6 GWh capacity significantly exceeds typical grid storage projects, with the largest operational battery storage project in the UK being 320 MWh and most German projects ranging from 50-200 MWh [2]. Group 3: Technology and Safety - The redox flow battery technology offers unique advantages for long-duration energy storage, utilizing liquid electrolytes based on vanadium or bromine, which are considered non-flammable due to their 75% water content [2]. Group 4: Integrated Development Model - The project distinguishes itself from conventional storage projects by integrating an AI data center, which will utilize waste heat to support the regional heating network, benefiting nearby towns and industrial facilities with high thermal energy demands [2]. Group 5: Economic Impact - Flexbase anticipates that the comprehensive facility will create 300-350 jobs in the local area [2]. - The project's location leverages Laufenburg's position as a core European grid hub, aiming to maximize revenue through cross-border arbitrage and grid services [2].
