| Abstract | The Krafla Magma Testbed (KMT) in northeast Iceland is the world’s first research infrastructure dedicated to developing and testing technologies for superheated/supercritical and near-magma geothermal environments. Located directly above a rhyolite magma body, KMT provides a unique opportunity to advance geothermal energy systems in conditions exceeding 400°C and 150 bar—well beyond the limits of conventional wells. KMT’s goal is to address the core challenges of operating in extreme geothermal settings, including well integrity, material durability, and high-enthalpy fluid handling. While specific technical solutions are still under development, the project builds on lessons from the Iceland Deep Drilling Project and is structured to support safe, iterative testing through a phased approach. This paper outlines how KMT serves as a globally relevant platform for scalable geothermal innovation. Its design emphasizes flexibility, international collaboration, and open-access science, enabling researchers and industry partners to explore solutions that could be applied in supercritical and volcanic regions worldwide. With almost 1 billion people living near active volcanoes, and geothermal energy making up a growing share of global renewables, accessing extreme-temperature resources is not only a challenge, but also, above all, a tremendous opportunity. KMT helps bridge that gap by combining energy research with volcanic monitoring and subsurface science. The presentation will describe the role of the Krafla Magma Testbed in shaping the future of supercritical geothermal energy, offering a model for how purpose-built infrastructure can drive technological advancement in one of the most demanding environments on Earth. |
