Recent studies on both sides of the Pyrenean mountain belt have revealed the presence of natural free hydrogen both seeping at the surface and trapped below ground (Lefeuvre et al 2021, Atkinson et al, 2022). Lefeuvre’s paper describes the optimal geological, solubility and temperature requirements for the generation, accumulation, and preservation conditions for hydrogen from studies in the Mauleon Basin near to Sauvete Beam, France.

In our studies in the Monzen-Barbastro area of northern Spain to the south, similar conditions are also observed, in fact free hydrogen has been recorded in well bores drilled in the 1960’s (e.g., Monzon-1). The location of these hydrogen gases is suggested to be related to serpentinization of oceanic crust or upper mantle, which given the oblique collision of the Iberian and European plates at the time of the Pyrenees formation resulted in mantle obduction rather than subduction below the mountain belt.

Learnings from ongoing studies in the Pyrenees suggest the generation of natural hydrogen is not unique and assuming similar plate collisional settings exist elsewhere they too might be prospective for natural hydrogen exploration.Learnings from ongoing studies in the Pyrenees suggest the generation of natural hydrogen is not unique and assuming similar plate collisional settings exist elsewhere they too might be prospective for natural hydrogen exploration.

SPEAKER BIOGRAPHY

Chris has over 35 years’ experience in the energy/resource sector working for both major companies (Shell, ARCO) and developing and arranging finance for his own and associates’ ventures. He was the co-founder of pda Limited which went on to become Serica Energy plc in 2004 and was also a founding investor in several other successful E&P start-up ventures between 2006-2016. In 2017 he co-founded Helios Aragon which is exploring for natural or “gold” hydrogen/helium gas in Spain and other countries.

Chris currently acts as a non-executive director of Rex International Holdings here in Singapore (SGX “REXI”) and as a board member for their subsidiary companies Lime Petroleum in Norway, Masirah Oil in Oman and Pantai Rhu Energy in Malaysia. In 2020 he was elected to the board of Far East Gold (ASX “FEG”) which is an eco-focused miner exploring for gold/copper in Indonesia.

Chris is a life member and past President (2005) of SEAPEX and holds both a BSc and PhD in Geology.
