A company based in Saskatchewan is currently engaged in drilling activities to extract hydrogen from underground sources on a commercial scale, aiming to shift from traditional fossil fuel-based production methods. Regina’s Max Power Mining recently initiated drilling its third well at the Lawson Complex, located in southern Saskatchewan. The company envisions establishing the world’s first large-scale commercial natural hydrogen system, offering a novel primary energy source.
Hydrogen is a versatile gas that can serve as a clean fuel and be utilized in fuel cells for electricity generation, producing only water as a byproduct. This characteristic makes it an attractive option for reducing emissions in challenging sectors like transportation and steel manufacturing. Currently, the majority of commercially available hydrogen, termed grey hydrogen, is derived from fossil fuels without emission reduction measures, leading to significant carbon dioxide emissions. In contrast, green hydrogen, produced through electrolysis of water using renewable energy sources, is less emission-intensive but comes with higher production costs.
Natural hydrogen, also known as white hydrogen, offers a promising alternative as it can be extracted from underground deposits with relatively lower greenhouse gas emissions compared to industrial production methods. The extraction process at the Lawson Complex leverages existing equipment and techniques used for natural gas and helium extraction, potentially leading to more cost-effective pricing. However, specialized techniques are required for drilling and extracting hydrogen compared to traditional oil and gas operations.
Natural hydrogen is formed through natural processes such as the reaction of oxygen with iron-rich rocks or radioactive decay of uranium and thorium, resulting in underground hydrogen deposits. While natural hydrogen discoveries have sparked global interest, including in Canada, challenges remain in efficiently extracting hydrogen from dissolved water deposits. Detailed assessments of hydrogen reserves, extraction methods, and market viability are crucial for determining the commercial feasibility of natural hydrogen projects.
As the natural hydrogen industry continues to evolve, ongoing research and exploration efforts will be essential in assessing the potential of natural hydrogen as a significant contributor to decarbonization initiatives globally.
