Exploring Geothermal Energy, Hawaii's Renewable Energy Frontier

Exploring Geothermal Energy: Hawaii's Renewable Energy Frontier

In a bold move towards achieving its goal of 100% renewable energy by 2045, Hawaii is venturing into the realm of geothermal energy. With abundant sunshine and wind being intermittent resources, the state is now turning its attention to tapping into geothermal sources to bolster its energy portfolio.

The Hawaii State’s Energy Office, led by Chief Energy Officer Mark Glick, is spearheading this initiative. Glick emphasizes the importance of understanding the potential of geothermal energy, stating, "For me, it’s a real priority for this office to better understand how far we can go with geothermal."

To kickstart this endeavor, $5 million from COVID federal relief funds have been allocated for conducting slim hole drilling to explore geothermal reservoirs. The focus of this exploration will initially be on Maui, with promising signs indicating the presence of viable geothermal sources along the rift zone of the island.

Currently, the Puna Geothermal Venture stands as the sole commercial geothermal power plant in Hawaii. Despite facing challenges, including a temporary shutdown following the 2018 volcanic eruption, the plant has recently received approval to increase its energy output to 46 megawatts, a significant boost from its current capacity.

Mike Kaleikini, the Hawaii Affairs Director at Puna Geothermal Venture, explains that this increase in production will be facilitated by the replacement of older power-generating units with modern, more efficient ones. This upgrade aims to not only enhance energy output but also mitigate potential environmental impacts and improve community relations.

Acknowledging past concerns about environmental impact and safety, Kaleikini underscores the importance of proactive outreach and communication with the community. He assures that steps have been taken to address past issues and regain public trust.

Looking ahead, the focus remains on expanding Hawaii's geothermal energy capacity. The identification of potential drilling sites on Maui signifies a step forward in this journey. While specific locations have not yet been disclosed, the narrowing down of options indicates progress towards harnessing the untapped potential of geothermal energy in the state.

That distinction is important for Denmark, where district heating is already a major part of the energy system ...

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 ...
