GEIOS partner presents deep geothermal lecture at IAH 2026

Professor Ladislaus Rybach of GEIOS Technologies delivered a Distinguished Lecture at the 53rd World Groundwater Congress in Budapest on September 15, 2026, focusing on how deep geothermal resources could help meet future electricity demand. The presentation highlighted nanotechnology-based methods aimed at reducing scaling and corrosion in hard-to-extract hot rock.

Why it matters: - Deep geothermal energy could add firm, local power as electricity demand grows. - The lecture centered on one of the field’s biggest barriers: hot rock that holds heat but resists conventional extraction. - GEIOS Technologies positioned its nanotechnology approach as a way to lower operating costs tied to scaling and corrosion.

What happened: - Professor Ladislaus Rybach, a partner of GEIOS Technologies, delivered the Distinguished Lecture for Session 2.1, "Groundwater-dependent geothermal systems," at IAH 2026 in Budapest. - The lecture took place on Tuesday, 15 September 2026, during the 53rd World Groundwater Congress of the International Association of Hydrogeologists. - The talk was titled "How to generate power from deep geothermal resources for the growing electricity demand in the future?" - Prof. János Szanyi and Abdelmoumen Shad Serroune co-authored the lecture.

The details: - The presentation focused on deep crystalline rock, which continuously generates heat through the natural radioactive decay of uranium, thorium and potassium. - Professor Rybach quantified that radiogenic heat in a widely cited 1976 study. - The core problem is permeability. The rock that contains the heat typically has little or no porosity, which makes extraction difficult. - The lecture described nanotechnology as a way to change that equation. - GEIOS Technologies’ radiogenic-heat approach was part of the presentation. - In peer-reviewed laboratory research co-authored by GEIOS founder Abdelmoumen Shad Serroune with research partners in Geothermics 142 (2026) 103810, the technology reduced silica scaling by up to 65.08%. - The same research achieved 94.05% corrosion protection efficiency. - GEIOS said the results target two major cost drivers in geothermal operations. - Serroune said, "Radiogenic heat is established science, Professor Rybach helped establish it." - Serroune said the company is working to "engineer our way into rock that nature made impermeable." - The lecture was co-authored with Prof. János Szanyi, PhD, a hydrogeologist-engineer and Honorary Associate Professor at the Department of Geology, University of Szeged. - Szanyi is associated with the Rybach Center. - Serroune is CEO and founder of GEIOS Technologies and head of Nanogeios Laboratory.

Between the lines: - The presentation linked a long-established geothermal science concept with newer materials and surface-engineering tools. - GEIOS is framing nanotechnology as a practical enabler, not a replacement, for deep geothermal development. - The lab results matter because scaling and corrosion can slow deployment and raise costs in geothermal systems. - The lecture also signaled a push to connect academic geothermal research with commercialization.

What's next: - GEIOS said its technology is lab-tested, lab-proven and patented. - Field trials are underway at three geothermal projects: two on existing wells and one greenfield project. - GEIOS also said testing is underway on SPARC. - The company said results will be published as data becomes available. - Congress information is available at IAH 2026 Budapest and the programme.

The bottom line: - GEIOS used a major hydrogeology conference to showcase a lab-backed approach aimed at making deep geothermal resources more usable and more economical.
