A Global Rollout Strategy: The EAPOLAB Initiative

To scale its geothermal vision, EAPOSYS is deploying AGS through EAPOLABs — national or regional consortiums bringing together engineering firms, utilities, and local authorities.

The first such platform, SwissDGS, was established in Zurich in late 2024 in partnership with Basler & Hofmann and Amberg Group. Through EAPOLABs, EAPOSYS ensures that every project aligns with local needs while maintaining world-class engineering and environmental standards.

EAPOSYS has also expanded internationally with EAPOSYS Canada, founded in Calgary, Alberta, during Q4 2024 — signaling a bold step into North American geothermal markets.

“Energy is at the core of every human society. Guarantee of supply, sustainability, affordability, and energy as a common good is an essential ethical attribute which EAPOSYS AGS strives to contribute to,” added Vouillamoz.

Dynelectro, Syntholene, and the Geothermal SOEC Breakthrough in Iceland

Dynelectro, Syntholene, and the Geothermal SOEC Breakthrough in Iceland Dynelectro’s role in the Syntholene Iceland project highlights a major shift in how the market should think about SOEC technology. For years, solid oxide electrolysis cells have been seen as highly efficient but too difficult to commercialize because of stack degradation, short operating life, and the complexity of integrating them into real industrial systems. This project helps challenge that view by showing how geothermal integration, advanced power electronics, and system-level design can make SOEC a credible industrial solution. The most important takeaway is simple: the market has often misunderstood SOEC as a technology limited by chemistry alone, when in fact a large part of the challenge is operational. Dynelectro’s approach shows that if the stack is controlled properly and supported by the right electrical architecture, SOEC can move much closer to commercial viability. The Syntholene Iceland ...

Driving the UK Toward Net Zero: Chris Sladen on Geothermal’s Untapped Potential

Alphaxioms, we talked to Chris Sladen about his involvement in geothermal both in the UK, and globally By: Robert Buluma Chris, please begin by explaining a little about yourself, and why you have a passion for geothermal? I have spent over 45 years involved in energy. Following undergraduate studies in geology at Southampton University, and a PhD in sedimentology at Reading University, I joined the energy sector in Aberdeen in 1980. It was a fascinating era when it seemed like at least one giant oil & gas field was discovered offshore every month; the wealth creation for the UK was gigantic. I got to see so much geology and rocks - my true passion. I moved to China in late 1983; not today’s China, this was over 40 years ago, a country closed for decades and embarking on an open-door policy, in part to bring both investment and technology. I became very interested in energy trends, energy politics, and new geography created by changing politics leading to opportunities for ene...
