LH2G already works as a frontrunner in natural hydrogen. The company works on few exploration programs and licenses in France and abroad. As part of its ongoing exploration program, LH2G is looking into technologies for derisking natural hydrogen play. It would like to answer this larger question: Could stimulating carbon-free fuels that are being produced naturally open up new energy solutions?

Natural hydrogen is currently a poorly understood but potentially groundbreaking energy resource. Developing knowledge on the subject for over 6 years, Dr. Eric Gaucher has been working on hydrogen chemical stimulation with Dr. Muriel Andreani, Professor at UCBL, and Dr. Samuel Barbier (UCBL), who was supervised during his thesis by these last two. In 2023, Jean Gaucher (LH2G) reinforces the team as data and project manager.

In this context in June 2023, the U.S. Department of Energy’s (DOE) Advanced Research Projects Agency-Energy (ARPA-E) invited Dr. Eric Gaucher. He presents technology ideas to enhanced natural hydrogen production and build a new energy industry. Following the meeting in Washington, ARPA-E announced the launch of a grant program with two Exploratory Topics to develop natural hydrogen technologies.

In 2024, ARPA-E has committed more than $20 million to 16 exploratory projects looking at technology ways to produce hydrogen as an energy source. LH2G consortium was one of 16 Teams Selected by DOE’s ARPA-E. What ARPA-E needed was partners. With geologic hydrogen largely unexplored as a field, ARPA-E started looking for translatable skills.
