Geothermal energy, harnessed from the Earth's internal heat, is gaining momentum as a reliable and sustainable power source. Recent technological advancements have significantly reduced drilling costs and time, making geothermal projects more economically viable. For instance, Fervo Energy's FervoFlex system employs horizontal drilling into hot rock formations, creating hot water and steam for energy storage and release. This method has decreased drilling time by 70% and lowered well costs from $9.4 million to $4.8 million. A pilot project with Google, launched in 2023, supplies energy to a data center in Nevada, demonstrating the potential of geothermal energy in meeting the growing demand for clean power. time.com
In addition to technological progress, supportive policies are accelerating geothermal energy development. Germany's economy ministry proposed a draft law to expedite the expansion of geothermal projects, aiming to phase out fossil fuels in heating systems by 2045. The legislation seeks to simplify approval processes for geothermal facilities, heat pumps, and related infrastructure, granting them a legal status of "overriding public interest." This approach aligns geothermal energy with other renewable sources like wind and solar, facilitating faster permitting and development. Such policy initiatives are crucial for unlocking the full potential of geothermal energy and achieving global climate goals. reuters.com
