There is nothing like a steaming hot cup of coffee early in the morning to wake up in the morning and feel more energized and ready for the day. Some prioritize other factors to energize, such as sleep, remaining hydrated, etc. However, others get a surge of adrenaline when drilling 20 km deep to reach a super-hot new energy source. It may be an entirely different type of energy, but it is valuable, as it will have us saying goodbye to all the coal in the world.
Researchers are targeting this super-hot new energy
It’s one thing to energize your mind and body, but it’s a whole other can of worms to provide sustainable energy to the global population. For too long, mankind has been burning fossil fuels to power the world, which has negatively impacted the climate. Carbon emission levels have been through the roof, and the only way to mitigate the effects of climate change is to turn to renewable sources.
Renewable energies are popular alternatives to fossil fuels, as they have little to no carbon emissions, but they are not without their obstacles, efficiency being the main one. Now, researchers are targeting a super-hot new energy that has the potential to meet all our power criteria. Accessing this energy is not as easy as it seems, but that won’t stop a particular start-up company.
This start-up plans on drilling 20 km deep into the Earth
A company from Massachusetts plans on drilling 20 km deep into the Earth to access an unlimited amount of energy that could power the world. The company, called Quaise Energy, was founded in 2018 and has been attempting daring approaches to provide the world with clean, sustainable power. While the approach may not be an entirely new concept, the purpose behind the approach is both admirable and unconventional.
According to Interesting Engineering, in 1970, scientists managed to drill 12 km into Russia’s Kola Peninsula simply to test how far they could push engineering limits. Now, Quaise plans to do the same, but will push the drilling limit a little further to harness a valuable energy called geothermal energy. Drilling into the Earth’s mantle and crust to obtain geothermal energy would result in providing the world with uninterrupted power without radioactive waste or carbon emissions.
The task might seem impossible, but where there’s a will, there’s a way. Conventional drilling is a slow and limited approach, and it is expensive. Matthew Houde, cofounder and chief of staff at Quaise, believes they have the answer to address all the challenges posed by drilling so deep into the Earth lies within a device called the gyrotron.
Using lasers to blast through hard rock
According to MIT Technology Review, we can theoretically harness Earth’s geothermal heat in any location in the world, but drilling that deep through extremely hard rock to access the required high temperatures is not easy. That is why Quaise plans on using the gyrotron, which releases high-frequency electromagnetic radiation, to blast, melt, and vaporize rock. In theory, this approach has the following benefits:
- Increased drilling speed
- Cost-effective drilling
- Increased access to geothermal energy
This gyrotron has a maximum power of 100 kW, and a cooling system is utilized to assist the gyrotron’s superconducting magnet in reaching nearly -200 °C. A filtration system also catches debris that the samples shed. Quaise announced in July that it accomplished drilling a 100-meter-deep hole at its field test site.
The company plasma-tested its approach at Sandia National Laboratories and hopes to accomplish a 3 km demonstration by 2026. The next step would be its first 100 MW pilot plant by 2030. According to CEO Carlos Araque, their strategy will prove that super-hot rocks can generate geothermal power efficiently.
