There are a fewThere are many sources of energy that is “free” on Earth, including solar, wind, hydro, geothermal, and hydro. Since thousands of years, humans have harnessed the power and potential of wind and water. We’re also very adept at harnessing the sun’s power. However, geothermal energy is still not well-exploited.
Geological hotspots such as Iceland and Northern California are home to most commercial-scale geothermal plants. Many homeowners also drilled shallow wells and buried loops in their yards to heat and cool their homes. To truly unlock the potential of geothermal power around the globe, and to make it profitable, we need new ways to drill deep into the Earth to warm the Earth.
Many energy experts are focusing on the power of the distributable base load as the world struggles through the energy transition. That’s a lot. “Detachable” means that grid operators can request a power plant at any moment and it will connect. Base Load refers to power that can be turned on no matter what the weather. Renewable energy sources like solar and wind energy do not provide base load energy. It’s quite a different story when it’s combined with batteries to store energy for when the sun isn’t shining or the wind is calm. Although renewables and batteries are growing at an increasing rate, batteries remain costly. Why not have more options?
We will need new methods of drilling deep into the Earth to heat the Earth in order to truly unlock the potential of geothermal power around the globe.
Geothermal energy is often referred to as a carbon-free source for distributable base-load energy. This is why energy giants love it so much. A working fluid, usually water, is injected underground and heated before being drawn back to work via a heat exchanger.
The heat source is virtually limitless. The earth is continually being created about 44 terawatts of heat,Natural radioactivity accounts for about half of this energy. Around 385,000 terawatt-hours are released each year. This is more than the global energy use in 2019. Just shy of 23,000 terawatt-hours. We would have more energy if we could harness even a fraction of the Earth’s heat.
Many engineers have had to rethink the careers of their colleagues as a result of the declining fossil fuel industry. Many of the drilling technologies that were developed for the oil-and-gas industry are compatible with mainstream geothermal energy.
Many start-ups are working to transform geothermal energies from a specialized source into one that can easily be used on a large scale. Here are five I have been following.
