Geyser Batteries, established in 2018 in Finland, is a specialized manufacturer of sustainable high-performance power batteries. The company brings over 25 years of continuous innovation in energy storage technologies to create efficient, safe solutions for industrial applications. Their focus on water-based electrolyte technology sets them apart in the energy storage sector, offering alternatives to conventional lithium-ion batteries. Geyser Batteries serves multiple industries, including power grid infrastructure, transportation systems, and heavy machinery operations, with a clear emphasis on environmental responsibility and sustainable manufacturing practices.
Battery Technology
Geyser Batteries’ proprietary technology combines elements of supercapacitors with secondary reduction-oxidation batteries in an innovative hybrid electrochemical system. The water-based chemistry eliminates the need for lithium and other critical raw materials, significantly reducing environmental impact while maintaining high performance standards. Their batteries feature:
- Fast charging capabilities (under three minutes)
- Extended lifecycle performance (hundreds of thousands of cycles)
- Zero fire risk due to aqueous electrolyte composition
- Uniform current density through bipolar design
- Minimal maintenance requirements
- Low-temperature operation capability
The technology utilizes recyclable materials throughout its construction, making it particularly valuable for applications requiring frequent power cycling, such as grid stabilization and industrial power systems. The redox reaction occurs on both electrodes, distinguishing it from other hybrid systems and enabling superior energy density while preserving rapid charge-discharge capabilities.
Recent Projects
In December 2023, Geyser Batteries signed a significant conditional supply agreement with Released Energy to provide 85 megawatts of their proprietary battery technology. This partnership focuses on distributed energy storage systems across Australia and the United Kingdom, supporting renewable energy integration and reducing curtailment in power generation.
The company has also expanded its board of directors, strengthening its organizational structure for future growth. Their involvement in renewable energy projects in Australia demonstrates their increasing international presence and commitment to sustainable energy solutions.
Investors
Geyser Batteries has secured backing from several notable investors, including Voima Ventures, which led a €1M seed round in 2019. The company’s financial support network includes Butterfly Venture Fund III Ky, Tesi (Finnish Industry Investment Ltd.), and the Ehrnrooth Family Office. In 2021, the company completed a bridge financing round with participation from existing investors, supporting continued technology development and market expansion.
