This US state is known for its delicious official state dessert, the Boston Cream Pie, and is also known for inventing the sport of basketball. On the note of a more natural phenomenon, and no, we’re not referring to Lake Chargoggagoggmanchauggagoggchaubunagungamaugg, this US state has discovered infinite energy, which is inside the state’s white, superhot rocks. If that’s not something worth mentioning, then we do not know what is.
The pursuit of clean energy sources
The pursuit of clean and reliable hydrogen sources escalates as the world seeks a future of greener energy. Hydrogen, the most abundant element in the universe, with the potential for clean combustion, is a riveting alternative to fossil fuels across various sectors. Some commonly think it only exists primarily with other elements, such as with oxygen in water, and with carbon in methane. However, naturally occurring underground white hydrogen is telling another tale as a potentially unlimited source of carbon-free power.
In Massachusetts, MIT Assistant Professor Iwnetim Abate’s research team planned on using a $1.3 million grant from the U.S. Department of Energy to determine the ideal conditions for producing white hydrogen underground while considering these factors:
- pH levels
- Temperature
- Pressure
- Catalysts to start chemical reactions
“Some catalysts are very costly and hard to produce, requiring complex production or preparation. A catalyst that’s inexpensive and abundant will allow us to enhance the production rate — that way, we produce it at an economically feasible rate, but also with an economically feasible yield.” – Postdoc Yifan Gaoo
Infinite energy inside white, superhot rocks in Massachusetts
White hydrogen is found within geological formations, such as basalt rock. These rocks are found across the United States, and chemical reactions occur within, like organic matter’s decay or water’s reaction with the rock. This makes it different from other hydrogen, such as grey hydrogen, made from natural gas, and green hydrogen, procured from renewable energy.
“We aim to optimize the reaction parameters to make the reaction faster and produce hydrogen in an economically feasible manner.” – Abate, the Chipman Development Professor in the Department of Materials Science and Engineering (DMSE).
Abate and Gao’s research team wants to optimize the reaction across various rock types and environments by creating what they call a high-throughput system, made up of artificial intelligence software and robotics, to test different catalysts and simulate what would occur when applied to different rocks from different environments, with different external conditions like temperature and pressure.
“And from that we measure how much hydrogen we are producing for each possible combination. Then the AI will learn from the experiments and suggest to us, ‘Based on what I’ve learned and based on the literature, I suggest you test this composition of catalyst material for this rock.’” – Abate.
The benefits of white hydrogen
White hydrogen can potentially play an important role in the hydrogen economy. Its direct extraction from geological formations offers many benefits:
- Abundance:
- White hydrogen reserves are estimated to be much larger than fossil fuels, offering a long-term and sustainable energy source.
- Environmentally friendly:
- White hydrogen extraction has a small carbon footprint, making it an eco-friendly alternative to fossil fuel-based hydrogen production.
- Cost-effectiveness:
- The lack of energy-intensive methods contributes to the potential for decreased production costs compared to other hydrogen types.
As the interest in hydrogen increases, it will be extremely useful for governments that are seeking carbon-free alternatives to fossil fuels such as oil and gas. However, ongoing research and development are important to understand whether hydrogen is polluting or not. White hydrogen may even advance technologies used for extraction, transportation infrastructure, and storage solutions, by decarbonizing the various sectors to make a smaller global impact on the environment.
