Sub-surface Technologies for the Generation and Production of Low-carbon Hydrogen from Hydrocarbon Resources

GTI Energy is leading projects focused on sub-surface technologies that enable the integration of hydrogen into our energy system to minimize climate change impacts.

In this feasibility study exploring generation and production of hydrogen underground, researchers will examine the available techniques for creating reactions in deep subsurface oil reservoirs to generate hydrogen.

This effort will identify the research questions and approaches that could guide future research investigations of these in-situ hydrogen production processes, and provide a techno-economic assessment to understand the economics. The research intends to inform and stimulate stakeholder thoughts around the future research needs on underground generation and production of hydrogen by addressing techno-economic challenges, societal and regulatory barriers to deployment, as well as technical advancements and investment needs for selected largescale subsurface technologies. The project is expected to kick off in 3Q 2022.

A Review and Techno-economic Analysis of Subsurface Technologies for Hydrogen Production from Fossil Fuel Resources

Reducing the carbon intensity of the energy sector is central to the transition towards a sustainable, zero-carbon future. Conversion of depleted hydrocarbon reservoirs into underground energy conversion systems that are accessible through available well infrastructure offers a promising pathway to leverage existing fossil fuel assets for low-carbon energy.

An article written by GTI Energy’s Shadi Salahshoor and Shaik Afzal recently published in the International Journal of Hydrogen Energy provides a review of subsurface technologies that can be used to produce hydrogen. It is accompanied by a preliminary techno-economic analysis (TEA) that explores potential market and environmental impacts and identifies key parameters that can effect overall process economics.

This important research performed on behalf of the LCRI explores how leveraging existing fossil fuel infrastructures for low-carbon hydrogen production could become a vital contributor to the decarbonization of energy systems.
