Eden’s Electrical Reservoir StimulationTM Technology Selected for $3.5 Million ARPA-E MINER Award

SOMERVILLE, Mass.–(COMMERCIAL WIRE)–Eden, a company developing novel techniques to increase permeability and characterize geological reservoirs, announced today that it has been selected as part of a project team to receive $3,517,450 in federal funding from the Department’s Agency for Advanced Research Projects of US Energy-Energy (ARPA-E) for a project titled “Integrated Electro-Hydraulic Fracturing and Real-Time Monitoring for In-Situ Carbon Negative Mining”. The funding is part of the ARPA-E MINER program, which prioritizes financing technologies that support novel approaches to increase mineral production while decreasing the energy required and subsequent emissions to mine and mine these energy-relevant minerals. . This project is being led by Idaho National Labs, which has been working closely with Eden to develop the technology for hard rock permeability enhancement applications. The Colorado School of Mines is also a sub-awardee on the project and will lead a novel effort to use distributed fiber optic sensing (DFOS) to monitor fracture processes and chemical reactions in the subsurface during reservoir electrical stimulation operations.TM.

“While we began to develop our electrical rock stimulation technology to increase the volume of heat transfer fractures to maximize energy production in geothermal reservoirs, we soon realized that the implications of our method go far beyond geothermal,” said Paris Smalls, Eden’s CEO and co-founder. “Sustainable and controlled enhancement of subsurface permeability can greatly reduce the environmental impact of extracting lithium, nickel, cobalt, copper, and other energy-relevant minerals by pre-weakening rock prior to mining operations. This makes it possible to reduce water consumption, energy crushing and mine tailings. In the very near future, we will also adopt our technology for other hard rock applications, including increasing the permeability of tight mafic/ultramafic reservoirs for geological production of hydrogen and COtwo sequestration, and the decrease in the number of newly drilled wells and the water needed to re-fracture unconventional reservoirs. It is a very exciting time to be in Eden!”

The project team consists of world-class researchers from the Idaho National Laboratory, Colorado School of Mines, Stony Brook University, and Eden. These institutions will work together to study the electrical stimulation processes of rocks, COtwo injection during mining operations and monitoring of DFOS in the mining workflow.

“Combining our novel rock permeability enhancement technology with DFOS will allow us to increase and measure permeability evolution with greater precision in COtwo reactive mineral bodies,” said Dr. Rafael Villamor-Lora, lead experimental scientist at Eden and Co-PI on the project. “This will allow our mining partners to unlock new sources of energy-relevant minerals, while drastically reducing their environmental footprint.”

Successful development of the technology will be essential to meet global demands for critical minerals and achieve net-zero decarbonization targets by 2050.


Eden GeoPower Inc. (“Eden”) is developing a new “electrical reservoir stimulation” technology to increase subsurface permeability with minimal environmental impact. Market applications include geothermal heat recovery, mining, geological hydrogen, and unconventional reservoir refracturing. Eden is headquartered at Greentown Labs in Somerville, MA, the largest cleantech incubator in North America. The company is backed by Good Growth Capital, Ameren, NSF-SBIR, and DOE ARPA-E.

The US Department of Energy (DOE) has awarded $39 million in funding for 16 projects in 12 states to develop market-ready technologies that will increase household supplies of critical items needed for the clean energy transition. The selected projects, led by universities, national laboratories, and the private sector, aim to develop commercially scalable technologies that enable increased domestic supplies of copper, nickel, lithium, cobalt, rare earth elements, and other critical elements. The Biden-Harris Administration has remained focused on strengthening the supply chain for critical materials, as rare earth elements are needed to make various clean energy technologies, from electric vehicle batteries to wind turbines and solar panels. President Biden has stressed the importance of implementing energy sources that reduce carbon pollution, lower costs for families and businesses, and ultimately mitigate the impacts of climate change.
