An Economic Analysis of In-Situ Hydrogen Production from Natural Gas Wells with Subsurface Carbon Retention.
Our economic analysis paper was published online in the peer reviewed SPE Journal. The SPE (Society of Petroleum Engineers) is the main professional society for the global oil & gas industry.
The study explores the economic viability of Metharc’s novel approach to hydrogen production directly from natural gas wells using wellbore gasification. This method converts methane into hydrogen while retaining carbon within subsurface geological formations, thereby reducing the release of greenhouse gases. Unlike traditional surface-based hydrogen production methods, this technology leverages the high temperatures and pressures present in wellbores to minimize the energy required for gasification. This approach not only cuts energy costs but also eliminates the need for post-combustion carbon capture, which is often expensive and energy-intensive.
The economic analysis revealed that this system could produce hydrogen at a cost well below 1 USD/kg, making it highly competitive with existing hydrogen production methods like steam methane reforming (SMR). By capturing carbon at the source, the method reduces life-cycle emissions and avoids the complexities of transporting and storing CO2. This innovative technology offers a sustainable solution for the hydrogen economy, potentially transforming natural gas wells into low-carbon energy assets while extending the life of hydrocarbon resources in an environmentally friendly manner.
