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…

Helium One’s bumpy road to success

Mariël Reitsma - HRH Geology
First of all, the rig. During the initial exploration campaign that started in 2021, Helium One used a slimline mining rig. This is probably a contributing factor to a range…

The North American helium fairway

Mariël Reitsma - HRH Geology
As always, news outlets concentrate on the handful of exploration companies trying to prove additional (helium) resources. For instance, Gold Hydrogen announced a record find of 17.5% helium in the…

Gold hydrogen – or Gold helium?

Henk Kombrink and Mariël Reitsma
On Wednesday 22 May, Gold Hydrogen’s share price reached its highest level so far at 2.09 Australian dollars. A few days later, following the release of an ASX statement on…
