Estimates of trapped hydrogen globally – a reality check

Arnout Everts, AEGeo
Over the last few years, there has been a continu­ous stream of news cover­age on “ground-breaking natural-hydrogen discoveries.” A paper by Ellis and Gelman, published late last year, very much…

Hydrogen exploration potential in Uruguay

Josefina Marmisolle, Cecilia Romeu, Santiago Ferro, Pablo Gristo, Juan Tomasini, Rodrigo Novo and Natalia Blánquez, ANCAP
Uruguay has completed the first phase of its energy tran­sition; most electricity is now generated from renewable sources. For the second phase, the coun­try has identified green hydrogen and its…

Iran to finally start producing helium

Mariël Reitsma, HRH Geology
Redrawn after IHS Energy and Google Earth. Iran is set to join the exclusive group of helium-producing coun­tries. With the launch of its pilot project to extract and purify heli­um…

Large hydrogen seep found in the Philippines

Mariël Reitsma, HRH Geology
The natural gas seeps at Mount Chimaera in Tur­key have been known since antiquity. They are easily recognis­able due to the constant burning of methane and hydrogen gas that seeps…

New hydrogen prospectivity map released for the USA

Henk Kombrink
“For decades, the conventional wis­dom was that naturally occurring hydrogen did not accumulate in suf­ficient quantities to be used for energy purposes,” says Sarah Ryker, United States Geological Survey (USGS)…

Can Oman engineer a subsurface hydrogen kitchen?

Mariël Reitsma, HRH Geology
Exploration for geological hydrogen has taken off over the past few years. However, nothing close to a major success case has been reported yet. Companies such as Gold Hydrogen in…

Play-based exploration methods used to find natural hydrogen

Giacomo Firpo, Paul Swire, Rakgas, Steve Lawrence, Ian Hutchinson, Nhsg and Jonathan Watson, Metatek
Ophiolites, consisting of obducted oceanic crust, form a logical candidate to explore for hydrogen because the process of serpentiniza­tion, which is common in olivine-rich rocks, results in the generation of…

Helium found in new and unexpected places

Mariël Reitsma, HRH Geology
In Finland, 80 Mile positively tested copper-zinc exploration boreholes, while Pulsar Helium has drilled an appraisal well in Minnesota after nickel exploration accidentally found helium. In South Africa, Renergen is…

Fairy circles

Mariël Reitsma, HRH Geology
Companies ex­ploring for natu­ral hydrogen are rapidly popping up everywhere, but how do the geologists decide where to start prospecting? Many of them look at historical data from “dry” hydrocar­bon…

Dry helium well supplies the beverage industry

Mariël Reitsma, HRH Geology
The USA is by far the world’s largest geological CO2 producer, extracted from a small number of high – CO2 reservoirs. The vast majority of this CO2, 97 %, is…
