The Harnyss microgrid will be paired with solar power on tribal grounds. The Guidiville Rancheria is a federally recognized Pomo tribe based in Mendocino County, California.
The Guidiville tribe, like numerous other native nations, wants to transition toward on-site renewable energy within its lands, thus enhancing energy sovereignty, reliability and lower costs. Harnyss says its Oasis platform can offer long-duration backup power and be operated off-grid.
The Fort Worth, Texas-based company, which was started up earlier this decade, has been developing the Guidiville Indian Rancheria microgrid project in tandem with Emtel Energy USA, Timberline Renewable Solutions, Colusa Indian Energy, 7Skyline, and Green-World Renewables.
“We are excited to work with Michael Derry and the Guidiville Council, as well as Phillip Martin of Emtel Energy USA, Sean Ahern of Timberline Renewable Energy, and our valued partners,” said Kirby Smith, CEO of Harnyss, in a statement.
Hydrogen is the lightest, energy-dense gas and does not contain carbon in its molecular chain. However, to be classified as clean or green hydrogen, it must generated in splitting the H2 from water by electrolyzers which are powered by carbon-free resources such as solar, wind, hydro or nuclear.
Harnyss debuted its Oasis microgrid-energy storage solution in 2024 and is partially focusing on native customers which often reside in remote regions. The so-called “microgrid in a box” is held within containers 20 to 40 feet long and can offer off-grid charging with things like electric vehicles, according to reports.
The company received some initial equity investment from Houston-based Riverbend Energy Group. Riverbend is known for investing in oil and gas assets, but sold some to focus on its non-operated segment several years ago and has focused some funding on energy transition technologies such as hydrogen and microgrids.
The Guidiville tribe received its federal recognition in 1992 and is headquartered within a portion of the Ukiah Valley.
