The article discusses the emergence of white hydrogen as a cost-effective and naturally occurring alternative to green and blue hydrogen. Unlike its counterparts, white hydrogen does not require inefficient conversion processes, making it a promising solution in the low-carbon hydrogen economy. With a forecasted global demand for low-carbon hydrogen set to increase significantly by 2050, the potential of white hydrogen is gaining traction. Despite being a nascent industry, white hydrogen presents an opportunity for oil and gas companies to lead its development, leveraging their expertise in subsurface operations. The article highlights key questions surrounding white hydrogen, including its characteristics, current industry interest, potential as an energy source, the involvement of various countries in its exploration, and the role of oil and gas companies in driving its growth. While the industry is still in the early stages and faces challenges such as regulatory uncertainties and the need for further research, white hydrogen holds promise as a cost-effective and environmentally friendly option in the transition towards a low-carbon future.
