The perfect convergence of
resources and opportunity.

Renewell’s patented technology stems from a simple idea: use pre-existing wells and the power of gravity to store and generate electricity.

In times of need, potential energy in our system can be captured by lowering a weight down the well, producing energy by turning a regenerative winch. The weight can remain near the bottom of the well until it makes economic sense to buy energy to lift the weight back to its starting point, thereby ‘charging’ the system. The Gravity Well system is unique among all other energy storage technologies in that, on average, each system will have a net-negative carbon footprint because idle wells are often leaking methane. 

Cleaning up the current (more on the way!) 2.6 million inactive oil and gas wells in North America will require $187B, take +100 years, and leak more than 664 million tons CO 2 e of methane. At the same time, wind and solar will never achieve majority market share without energy storage capable of both short and long duration. Renewell is partnering with oil and gas companies to seal and convert over 1.8M wells to drastically increase the pace of their clean up at a lower cost, while also reducing methane emissions, creating 132GWh of storage ( ~5% of market share in 2050 ), and providing storage services with unrivaled flexibility.
