High-Density Hydro® is a grid-scale energy storage [ES] solution. It turns the supply of ultra-cheap, intermittent, renewable energy into stable & reliable electricity grids.

Excess energy is stored in tanks underground within small hills that can be found nearly everywhere, creating thousands of siting opportunities. Our research suggests that HD Hydro can be low-cost, fast to build & globally scalable with existing decentralised supply-chains.

The global ES market is growing & is predicted to be worth $620bn by 2040. The LDES Council forecast $1.5-3.0tr of investment in ES by 2040.

Nations are simultaneously transitioning away from fossil-fuels, creating incredible opportunities in short time frames, due to the climate crisis.

RheEnergise’s 2021 progress:

- Incorporated a 100% owned Canadian subsidiary due to the talent pool in Montreal & N. American market opportunity

- Validation of key technologies (inc. fluid) in progress

- Formulation science partnership with Greenwich University

- 3 trademarks, 2 patent pending filings

- Generated inquiries from interested parties around the world
