CedarStone Energy is a Central Alberta–based research and development company dedicated to advancing sustainability and accelerating the transition to green energy. We focus on innovating cleaner, more efficient pathways for renewable fuel production—specifically, the generation of green hydrogen through the repurposing of existing oil and gas infrastructure. By leveraging proven subsurface assets and applying forward-thinking engineering, CedarStone Energy is redefining what’s possible in sustainable energy development.

We are currently partnering with the University of Calgary’s Master of Science in Sustainable Energy Development program to advance a pioneering concept: the integration of geothermal heat and legacy oil & gas wellbores to reduce the energy intensity and cost of green hydrogen production.

This research address a critical barrier in the hydrogen economy—the high electricity demand of electrolyzers, particularly for water pre-heating. By using geothermal heat harvested from existing wellbores, our approach offers an innovative pathway to significantly improve system efficiency and reduce operating costs. 

CedarStone Energy aims to validate a transformative approach capable of unlocking cleaner, more cost-effective green hydrogen production in Western Canada and beyond.
