Water in Salt Sp. z o. o.

Water in Salt is a CleanTech company developing the next generation of safe and cost-efficient energy storage systems. In response to the growing global demand for sustainable energy, we’ve designed a breakthrough solution: a membrane-less redox flow battery based on water and salts, redefining how the world stores electricity.

Our technology delivers:

• Lower cost – target price under $100 per kWh,
• Enhanced safety – no fire risk like lithium-ion batteries,
• High durability – more than 10,000 charge-discharge cycles,
• Near-perfect efficiency – minimal to zero self-discharge,

• Sustainability – made from abundant and non-toxic materials.

   

After successfully completing our Proof of Concept trials, we’ve validated the exceptional performance of our system.

Water in Salt is not just a technological breakthrough – it’s a team of passionate scientists, engineers, and entrepreneurs building a cleaner, safer, and more affordable energy future.
