While everybody is talking about global warming and Li-ion based energy storage, we have found a way to use water as a highly potent capacitor and solve the most crucial problem of electrical grids: high peak demands, which are wholly subjected to cooling demands, e.g., commercial chillers.

We have developed the cleanest, safest, most cost-effective energy storage system available today and in the foreseeable future.




A rare earth material

Highly active, with a high environmental impact

When extracted, it is poisonous and unsafe

Experiences high degradation over 10 years of usage

Near Impossible to recycle




100% safe and clean

No negative impacts on the environment

Limitless charge cycles

Water is forever

100% recyclable


the future?

We are devoted to what we are doing, because we know this will change the world 🙂

The NREL states that in order to achieve the goal of 50% of the power in California coming from solar energy by 2030, this shift must be supported by an addition of at least 15 GW of storage.

15 GW represent just around 60 GWh of storage.

With current battery technology, every kWh requires ~0.9 kg (source) of LCE (lithium carbonate equivalent). Therefore, 1 MWh requires 900 kg, and 1 GWh requires 900,000 kg.

So for 60 GWh of storage, we need around 54,000,000 kg of LCE, to be replaced once every 10 years. And this is for California alone.

Can you actually imagine this amount of Lithium being extracted, used and then, after 10 years, trashed, when 60-75% of it can be easily replaced with water?

We are here to ensure that a reasonable alternative exists for the sake of the renewable grid.
