[ 01 ]About

Renewell converts the millions of stranded inactive oil and gas wells, along with their supporting infrastructure, into the lowest-cost, highest GHG-abating, most flexible energy storage device in the world. By converting ⅓ of all inactive wells in the US, Renewell can create 78,000 MWh of storage (10% of the needed capacity to reach ~80% renewable market share) and abate 2.3MMTCO2e of leaked methane annually (equivalent to removing 500k ICE cars/year). Renewell retrofits grid-connected inactive wells with a proprietary weight-based energy storage device with an intelligent controls platform that integrates with existing SCADA networks or uses cellular data for remote monitoring/control. This zero-self-discharge, distributed energy storage network can be coordinated to operate simultaneously, sequentially, or anywhere between to generate both short (2-8 hours) and long duration (weeks-months) power, providing first-of-its-kind flexibility and resilience.
