A company in Saskatchewan is currently engaged in drilling operations to extract hydrogen from beneath the earth’s surface, aiming to demonstrate the viability of extracting hydrogen on a commercial scale without relying on fossil fuels.
Regina-based Max Power Mining recently initiated drilling at the Lawson Complex in southern Saskatchewan, marking its third well at the site. The company envisions creating the world’s first large-scale commercial natural hydrogen system, introducing a new primary energy source.
According to Chad Levesque, the president and director of the company, hydrogen plays a vital role in various industrial processes, such as producing ammonia and refining petroleum. However, to ensure a more environmentally friendly sourcing method for this crucial molecule, the focus has shifted towards naturally occurring hydrogen deposits.
Hydrogen, a versatile gas that can serve as a fuel or be utilized in fuel cells to generate electricity, has gained attention for its potential to reduce emissions in challenging sectors like transportation and steelmaking. Presently, over 80% of commercially available hydrogen is grey hydrogen, produced from fossil fuels without emission reduction measures, resulting in significant carbon dioxide emissions.
Contrastingly, green hydrogen, produced through electrolysis of water using renewable energy, offers lower emissions but comes at a higher cost. Natural hydrogen, also known as white hydrogen, presents an alternative that could be extracted more sustainably from underground deposits, potentially leading to reduced greenhouse gas emissions and cost-effective pricing.
Natural hydrogen originates from natural processes underground, such as the reaction between oxygen and iron-rich rocks or the radioactive decay of uranium and thorium. While rich deposits of natural hydrogen are considered rare finds due to their volatility and reactivity, recent discoveries in Canada, including Saskatchewan, northern Ontario, Quebec, and Nova Scotia, have sparked interest in this emerging energy source.
Despite the promising potential of natural hydrogen, challenges remain in extracting it efficiently. The exact quantity of hydrogen available at extraction sites like Lawson Complex is yet to be determined, with ongoing efforts to evaluate the feasibility of extraction methods and assess market demand. While early-stage projects in various regions show promise, the global impact of white hydrogen on decarbonization efforts remains uncertain, emphasizing the need for continued research and development in this field.
