Greenest and cheapest MW-minute battery storage
CEO at Geyser Batteries
Mikkeli, Finland
About
Geyser Batteries is developing affordable, and sustainable high-power batteries, commercialising our proprietary and revolutionary water-based electrochemistry. Within 6 years, we created a new class of energy storage – a unique hybrid between supercapacitors and batteries that doesn’t rely on Li-ion technology and uses only low-cost and sustainable materials and production methods.
Our batteries are the ideal solution for cheap and green MW-minute storage. They:
-
Respond in less than 1 millisecond,
-
Can be fully charged in 3 minutes,
-
Store up to 5 times more energy than supercapacitors, and
-
Last up to 1 million cycles.
We produce batteries from sustainable, abundant, and cheap materials like carbon black for electrodes, at low-CAPEX facilities using standard manufacturing methods.
Today, we are developing the greenest and cheapest MW-minute energy storage technology.
And for tomorrow, we are set to build the first carbon-negative battery.
