There is evidence that hydrothermal plants can lead to an even greater earthquake frequency. Enhanced geothermal systems (hot dry rock) can also increase the risk of small earthquakes.

(See How Natural Gas Works for more information.) Earthquake risk associated with enhanced geothermal systems can be minimized by siting plants an appropriate distance away from major fault lines.

Chuck Darwin<p>Naturally occurring underground pockets of pure hydrogen are generating attention as a potentially unlimited source of carbon-free power.
&nbsp;
One interested party is the U.S. Department of Energy, which last month awarded $20 million in research grants to 18 teams from laboratories, universities, and private companies to develop technologies that can lead to cheap, clean fuel from the subsurface.

The U.S. Geological Survey estimates there are potentially billions of tons of geologic hydrogen buried in the Earth’s crust. <br>Accumulations have been discovered worldwide, and a slew of startups are searching for extractable deposits. <br>One of the grant recipients, MIT Assistant Professor Iwnetim Abate’s research group, will use its $1.3 million grant to determine the ideal conditions for producing hydrogen underground <br>— considering factors such as catalysts to initiate the chemical reaction, temperature, pressure, and pH levels. <br>The goal is to improve efficiency for large-scale production, meeting global energy needs at a competitive cost.<br>Abate is looking to jump-start the natural hydrogen production process, implementing “proactive” approaches that involve stimulating production and harvesting the gas.<br><a href="https://news.mit.edu/2024/iwnetim-abate-aims-extract-hydrogen-rocks-0408" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">news.mit.edu/2024/iwnetim-abat</span><span class="invisible">e-aims-extract-hydrogen-rocks-0408</span></a></p>
