Exergy Signs 33 MWe Geothermal Contract with Maren in Türkiye Exergy International has signed a new contract with Maren Maraş Elektrik Üretim A.Ş. to supply the 33 MWe Mehmet Ege geothermal power plant in Germencik, in Türkiye’s Aydın province. The project will use Exergy’s Organic Rankine Cycle technology and include the company’s largest Radial Outflow Turbine supplied to date. Expected to enter operation in the second half of 2027, the plant will provide renewable baseload electricity from a geothermal resource with an estimated temperature of approximately 160°C. The agreement represents another major step in Exergy’s long-standing relationship with Maren and reinforces Türkiye’s position as one of the world’s most active geothermal markets. A Major Geothermal Investment in Aydın The Mehmet Ege geothermal power plant will be located in Germencik, a district within Aydın that has become a major centre for geothermal development.

Revolutionizing Geothermal Energy: Rodatherm's Game-Changing Approach in Utah
Posted by Alphaxioms Geothermal News on January 17, 2026
Utah-based Rodatherm Energy Corporation has revolutionized the geothermal energy equation, and venture capitalists have taken note. With pilot projects planned for Millard County and Beaver County, the company has what founder and CEO Curtis Cook calls “a novel approach” to geothermal technology.
In a world racing toward sustainable energy solutions, geothermal power has long been a reliable but underutilized player. Traditional geothermal systems rely on water to extract heat from the Earth's depths, often limiting their deployment to remote, sparsely populated areas due to environmental concerns and high costs. But Rodatherm is flipping the script with its innovative, waterless closed-loop system that promises efficiency, scalability, and minimal environmental impact.
At the heart of Rodatherm's technology is what Cook describes as "a heat pump, no different than any other heat pump—all we did was take that technology and put it underground." This closed-loop system uses organic working fluids or refrigerants instead of water, eliminating contaminants and reducing strain on local water resources. The result? A setup that's reportedly 50% more efficient than conventional water-based geothermal generation, with lower operational costs and a lifespan spanning multiple decades. Unlike enhanced geothermal systems (EGS) like those tested at Utah FORGE, which involve fracturing rock reservoirs, Rodatherm's method employs a fully isolated fluid that drives a power-generating turbine directly, converting heat to power at very low cost.
This breakthrough allows geothermal energy to thrive in environmentally sensitive, high-density population areas—places where traditional methods would be impractical. "Historically, geothermal is in locations with sparse populations. What this technology can do is bring it to environmentally sensitive areas with high-density populations," Cook explains. Utah, with its high thermal gradients offering hotter temperatures at shallower depths, is an ideal proving ground for this innovation.
The excitement around Rodatherm culminated in September 2025 when the company closed an oversubscribed $38 million Series A funding round—the largest first venture raise for a geothermal startup in history. Led by Evok Innovations, the round included heavyweight investors like TDK Ventures, Toyota Ventures, TechEnergy Ventures, MCJ, Active Impact Investments, Renewal Funds, the Grantham Foundation for the Protection of the Environment, and Giga Investments. This influx of capital will fuel the construction and deployment of Rodatherm's pilot geothermal system in Utah, validating the design at commercial scale with a secured offtake agreement from local utility UAMPS.
The pilot projects in Millard and Beaver Counties are set to demonstrate the system's potential. Approved by the Bureau of Land Management (BLM) and local commissioners, the initiative includes a 3.6 MW test bed on federal lands, with plans to scale up to a full 100 MW facility. Drilling involves going two miles deep and then two miles horizontally to form a loop, leveraging proven oil and gas techniques to minimize risks. Rodatherm aims to break ground in early 2026, complete the initial loop by late 2026, and expand using project finance.
Founded by serial entrepreneur Curtis Cook, who previously built and scaled Vesta Energy, Rodatherm operates from hubs in Salt Lake City and Calgary. Cook's vision is clear: "The geothermal industry is at an inflection point, and Rodatherm is uniquely positioned to deliver a scalable, cost-effective solution for clean, secure baseload power." With a land base supporting over 300 MW of versatile power generation in the Great Basin region, the company is poised to lead the next wave of geothermal advancement.
As supportive policies like Utah's Project Gigawatt and federal incentives align with growing investor interest in decarbonization, Rodatherm's story is one of timely innovation. "We love working in Utah. The people are fantastically nice," Cook says, highlighting the state's pro-business environment. For geothermal enthusiasts, this could mark the dawn of a new era where clean, baseload energy becomes accessible everywhere.
