A startup spun out of MIT wants to drill deeper into the Earth than any geothermal company has gone before, and it has picked Oregon as the proving ground. Quaise Energy announced Project Obsidian in late 2025, claiming federal land leases in the state and setting a target of 50 megawatts of electricity from rock heated above 300 degrees Celsius. Phase 1 is slated to be operational by 2030. If the company delivers, it would mark the first time superhot geothermal energy has powered a commercial plant anywhere in the world.
That is a massive “if.” As of April 2026, no independent regulator or engineering body has validated the timeline, and several critical milestones remain unmet. But the federal leasing activity behind the project is real, and the technical concept has drawn serious academic attention.
The federal land position
The foundation of Project Obsidian is a set of geothermal leases on Bureau of Land Management land in Oregon. The BLM scheduled a competitive geothermal lease sale for July 2025, opening parcels across the state for energy development. Quaise says it secured leases around that period, and a Stanford University workshop paper by Dichter and colleagues states the company holds 1,334 acres of BLM geothermal leases acquired in 2025.
The BLM’s lease sale announcement is an official government action, but it does not name winning bidders. The federal government maintains a public records system called LR2000 where geothermal lease ownership, including serial numbers, acreage, and effective dates, can be verified. As of this writing, no publicly available LR2000 query results have surfaced to independently confirm Quaise’s specific parcels. The 1,334-acre figure currently rests on the company’s statements and the Stanford paper’s reference to them.
The technology behind the bet
Conventional geothermal plants tap naturally occurring hot water or steam relatively close to the surface, typically at depths of two to three kilometers. They work well in volcanic regions like Iceland or parts of Nevada, but they are geographically limited. Quaise wants to go far deeper, potentially beyond 10 kilometers, where rock temperatures exceed 300 degrees Celsius almost everywhere on Earth.
The company’s key innovation is millimeter-wave drilling, a technique that uses high-frequency electromagnetic energy to vaporize rock rather than grinding through it with a mechanical bit. The approach was developed at MIT and has been tested in laboratory and controlled field settings. Quaise has received funding from the Department of Energy’s ARPA-E program and has raised private capital through multiple venture rounds, most recently a Series B that brought its total funding past $100 million.
The 50-MW capacity target is not arbitrary. According to a news release distributed through EurekAlert, Quaise ties the figure directly to the Dichter et al. Stanford Workshop analysis, which evaluated the energy potential of drilling into superhot rock at the Oregon site. That paper provides the technical basis for the output claim. It is worth noting, however, that a workshop paper is not a peer-reviewed journal article; it has not undergone the same level of external scrutiny.
Why superhot geothermal matters
Geothermal energy currently accounts for less than 0.5 percent of U.S. electricity generation, largely because usable heat is accessible in only a handful of locations. Superhot geothermal, if it works at scale, could change that equation dramatically. Water or other fluids injected into rock above 374 degrees Celsius (the supercritical point for water) can carry roughly ten times more energy per unit than conventional geothermal fluids. That means fewer wells, smaller surface footprints, and potentially lower costs per megawatt.
Quaise is not the only organization chasing deep or enhanced geothermal. Fervo Energy has built a commercial enhanced geothermal plant in Nevada using horizontal drilling techniques borrowed from the oil and gas industry. Iceland’s Deep Drilling Project (IDDP) encountered superhot steam at its Reykjanes well, demonstrating that the resource exists, though harnessing it at commercial scale remains an unsolved engineering problem. What distinguishes Quaise is the depth of its ambition and the novelty of its drilling method, both of which carry proportionally higher technical risk.
What stands between announcement and power plant
Several concrete milestones would need to fall into place before Project Obsidian moves from aspiration to operating infrastructure. First, independent confirmation of Quaise’s land position through BLM’s LR2000 records would verify the project’s geographic foundation. Second, filings for drilling permits or environmental assessments with Oregon state agencies or the BLM would signal that engineering work has advanced beyond the theoretical stage. Third, a power purchase agreement with a utility would indicate the electricity has a buyer and a price, which is typically the clearest signal that a generation project will actually get built.
None of those markers have appeared in the public record as of April 2026. The 2030 operational date, cited in Quaise’s own communications, would require the company to compress federal and state permitting, well drilling at unprecedented depths, plant construction, and grid interconnection into roughly four years. For context, conventional geothermal projects in the western United States often take five to seven years from lease acquisition to first power delivery, and they rely on proven technology.
What to watch next
The BLM’s decision to hold geothermal lease sales in Oregon reflects genuine federal interest in expanding clean energy production on public lands, a priority that has accelerated under recent policy directives. Quaise’s bet is that its drilling technology can unlock heat sources no one else can reach. The Stanford analysis suggests the physics support the concept. The question is whether physics, engineering, permitting, and financing can all converge on the same timeline.
For now, Project Obsidian is best understood as the most ambitious geothermal proposal in the United States, backed by federal leasing activity, academic analysis, and significant venture capital, but not yet validated by the regulatory and commercial steps that separate announcements from operating power plants. The next six to twelve months should reveal whether Quaise begins filing the permits and securing the contracts that would make a 2030 start date plausible rather than aspirational.
