Geothermal Power Plant Equipment: Turbines, Pumps, Heat Exchangers and Leading Suppliers Geothermal power plants convert heat stored beneath the Earth’s surface into reliable, low-carbon electricity. Unlike solar and wind generation, geothermal plants can operate continuously, making them an important source of baseload renewable power. However, geothermal development is technically demanding because the resource is often hot, corrosive, mineral-rich, and variable in pressure and chemistry. The equipment used in a geothermal power plant must therefore be engineered for durability, high availability, and efficient heat conversion under challenging operating conditions. The central equipment package in a geothermal power plant generally includes turbines or Organic Rankine Cycle expanders, pumps, heat exchangers, separators, condensers, reinjection systems, electrical generators, transformers, switchgear, and control systems. Each component must be selected in relation to the characteris...
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.

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.
