EIG Geothermal Catalyst Partners Launches Inaugural Power Planet Investment

EIG’s First Geothermal Bet Signals a New Phase for EGS Financing Image : Thematic image of a geothermal plant EIG Geothermal Catalyst Partners’ inaugural investment in Power Planet is a meaningful signal for the geothermal sector because it links development capital with a project that already has infrastructure, interconnection capacity, and subsurface data on its side . For an industry that often struggles to move from concept to bankable execution, that combination can shorten timelines and reduce risk. Why This Deal Matters The core story is not just that EIG made its first investment; it is that the fund is targeting the middle of the geothermal value chain, where projects need capital to clear technical and commercial hurdles . That matters because enhanced geothermal system, or EGS, projects can be highly promising but capital-intensive, especially before they reach a stage where traditional infrastructure investors feel comfortable stepping in . Power Planet’s Star Peak proje...

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...
