Exploring Geothermal Energy, Hawaii's Renewable Energy Frontier

Exploring Geothermal Energy: Hawaii's Renewable Energy Frontier

By : Robert Buluma

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.

We also understand that Geothermal could be misunderstood but this article Compiles and in-depth introduction to this gem

As Hawaii continues its transition towards a sustainable energy future, the exploration of geothermal resources represents a crucial milestone. By diversifying its renewable energy sources, the state not only moves closer to its ambitious renewable energy goals but also sets an example for others to follow in the global fight against climate change.

Amsterdam Strikes Geothermal Gold: Hot, Thick, Permeable Reservoir Confirmed

Breakthrough Beneath the Beach: Amsterdam Region Hits Geothermal Paydirt at Strandeiland By: Robert Buluma The Netherlands just took a giant leap toward fossil-free heating. On the artificial island of Strandeiland (part of Amsterdam’s fast-growing IJburg district), the SCAN exploration well has officially confirmed what the geothermal community has been hoping for: a thick, hot, and , most importantly permeable reservoir in the Slochteren Formation. Key numbers that matter:   Reservoir thickness: 152 meters   Bottom-hole temperature: 66 °C   Permeability: confirmed via successful production and injection tests   That’s not screaming-hot by Icelandic standards, but for direct-use district heating in one of Europe’s densest urban areas, 66 °C is more than enough to supply thousands of homes with clean, baseload heat – forever. Why This Well Changes Everything for the Netherlands The Dutch government launched the SCAN program (Seismic Campaign Nethe...

Zanskar’s Big Blind: First Blind Geothermal Discovery in 30 Years

Big Blind: The Geothermal Discovery That Changes Everything By: Robert Buluma Utah startup  Zanskar Geothermal quietly dropped one of the most important announcements in American energy in decades. They discovered and confirmed “Big Blind” ,the first completely blind, commercial-grade geothermal system found in the United States in over thirty years. Let that sink in. No hot springs.   No fumaroles.   No steaming ground.   No prior wells.   Zero surface expression whatsoever. Just desert, sagebrush, and – 7,000 feet below,  a reservoir hot enough and permeable enough to support gigawatt-scale power production. This isn’t incremental progress. This is a paradigm breaker. Why “Blind” Discoveries Matter So Much For the last 40 years, geothermal development in the U.S. has been geographically handcuffed. You could only build plants where nature advertised the resource on the surface – think Yellowstone, The Geysers, or Imperial Valley. Ever...
