ZemQuest

About

ZemQuest is a private headquartered in Noordwijk, Netherlands with approximately 10-50 employees specializing in Energy Storage, Hydrogen.

ZemQuest develops aluminum as an energy carrier for electrification of machinery at remote or grid-congested sites. Their aluminum-air battery technology combines aluminum fuel plates with novel solid fuel cell designs, enabling emission-free operation of light to medium heavy machinery. The system works by combining aluminum with ambient oxygen to produce aluminum hydroxide and electrical energy. A key advantage is the ability to resmelted aluminum hydroxide back into fresh aluminum for reuse, creating a circular economy. The company targets 5x range extension for vehicles and 25x energy density per 20-ft container compared to conventional solutions. Technology is designed for modularity with macro-components and monomaterials, uses 150x fewer rare minerals than lithium-ion batteries, and performs reliably across temperature extremes.
