”The Future Is Under Our Feet”
Welcome To Advanced Geothermal Energy Technologies
American GeoPower (AGP) is the original granted patent holder and pioneer of advanced geothermal closed-loop molten salt systems and molten-salt thermal energy storage for geothermal applications worldwide.
AGP was the first company in the world to define and introduce advanced geothermal closed-loop molten salt systems and molten-salt thermal energy storage concepts for geothermal applications. AGP also introduced key concepts and terminology including “Geo Salt,” advanced geothermal closed-loop systems, and advanced geothermal closed-loop molten salt systems. These groundbreaking technologies continue to help lead the evolution of ultra-high temperature geothermal energy worldwide.
AGP recently presented a technical paper at Stanford University’s Geothermal Workshop addressing high-temperature molten-salt closed-loop geothermal systems, thermal drawdown mitigation, and thermal buffering through molten-salt thermal energy storage.

AGP holds 15+ granted U.S. patents and internationally granted patents in over 70 countries covering advanced geothermal closed-loop systems, molten-salt thermal energy storage, geothermal heat extraction, and related geothermal technologies. Our intellectual property portfolio extends across multiple sectors of the geothermal and thermal energy industries and represents years of advanced engineering and development.
American GeoPower develops innovative and practical solutions designed to transform how geothermal energy is accessed, harvested, stored, and distributed. Our technologies are focused on delivering reliable 24/7 baseload renewable energy, industrial heat, thermal energy storage, desalination, green hydrogen, green ammonia, and other large-scale clean energy applications.
A key component of AGP’s geothermal technology platform is the use of molten salts in advanced closed-loop systems capable of extracting thermal energy from hot briny fluids, ultra-high temperature hot rock, and potentially even magma. These are the types of geothermal resources capable of unlocking the true long-term potential of geothermal power generation.
AGP’s patented systems are designed around commercially demonstrated components and technologies already operating successfully in other industries, including concentrated solar power (CSP), industrial heat transfer, oil & gas, drilling, and power generation. Our focus is on integrating proven industrial technologies into advanced geothermal applications capable of scaling globally.
What sets AGP apart is our entire suite of integrated solutions designed to function together as one unified energy platform. From geothermal heat harvesting to molten salt thermal storage and industrial heat applications, AGP’s technologies are designed to work together to help reduce greenhouse gas emissions while supporting long-term global economic growth and energy security.

SAND82-2377 Unlimited Release Printed October 1982 – Final Report – Magma Energy Research Project John L. Colp, Geophysics Division 1541, Sandia National Laboratories, Albuquerque, NM 87185 Distribution Category UC-66
Abstract
The DOE-funded, 7-year research project conducted by Sandia National Laboratories to assess the scientific feasibility of extracting energy directly from buried magma sources in the upper 10 km of the earth’s crust has been completed successfully. Scientific feasibility (the demonstration, by means of theoretical calculations and supporting laboratory and field measurements, that there are no known insurmountable theoretical or physical barriers which invalidate a concept or process) was demonstrated for the concept of magma energy extraction.
The U.S. magma resource is estimated at 50,000 to 500,000 quads of energy — a 700- to 7000-year supply at the current U.S. total energy use rate of 75 quads per year. Existing geophysical exploration systems are believed capable of locating and defining magma bodies and were demonstrated over a known shallow buried molten-rock body. Drilling rigs that can drill to the depths required to tap magma are currently available, and experimental boreholes were drilled well into buried molten rock at temperatures up to 1100°C.
Engineering materials compatible with the buried magma environment are available, and their performances were demonstrated in analog laboratory experiments. Studies show that energy can be extracted at attractive rates from magma resources in all petrologic compositions and physical configurations. Downhole heat extraction equipment was designed, built, and demonstrated successfully in buried molten rock and in the very hot margins surrounding it. Two methods of generating gaseous fuels in the high-temperature magmatic environment — generation of H₂ by the interaction of water with ferrous iron, and H₂, CH₄, and CO generation by the conversion of water–biomass mixtures — have been investigated and show promise.
