Natural hydrogen exploration offshore Southern Cuba

Marcello Rebora - Petroleum Geologist
It is generally accepted that most of the natural hydrogen is generated by reaction with water and ophiolites of the mantle, locally obducted towards the surface. Hydrogen tends to escape…

Natural hydrogen: Is it here to stay or will the bubble burst?

Mariël Reitsma - HRH Geology
The conference opened strongly with a keynote by Viacheslav Zgonnik from HyReveal, tackling this question. His market research shows that the number of companies exploring for natural hydrogen is rapidly…

Subsurface bio-stimulated hydrogen

Mariël Reitsma, HRH Geology
The quest for affordable, low-carbon hydrogen is far from over. While well-established techniques such as steam reforming and electrolysis exist, they come with significant drawbacks in terms of cost and…

The Koloma Enigma

Mariël Reitsma, HRH Geology
The company describes itself as a technology-enabled explora­tion firm that leverages indus­try expertise, proprietary data, specialised exploration tools, and ad­vanced data analytics to facilitate large-scale natural hydrogen production. Backed by…

Sometimes an old well is better than a fancy new one

Mariël Reitsma, HRH Geology
While there is always press around he­lium discoveries, companies that are actually producing it often go unno­ticed. That doesn’t mean they don’t have interesting stories to tell. Ca­nadian-based Thor Helium,…

Cuba – the next hydrogen hotspot?

Henk Kombrink
“I have concluded that this area should not be explored for oil, but for hydrogen instead. And I believe that the potential is colossal,” wrote Marcello Rebora in his email.…

A surge in exploration for natural hydrogen

Mariël Reitsma, HRH Geology
The global search for natural hydrogen is centered around a few hotspots, and the Tim­iskaming Graben in Canada is one of them. The graben is locat­ed on the Canadian Shield,…

Successful near-field helium exploration

Mariël Reitsma, HRH Geology
Blue Star Helium and joint venture partner Helium One, have successfully conclud­ed a six-well development campaign at the Galactica project in Las Animas County, Colorado. The company reported positive re­sults…

A helium reservoir in fractured basement

Mariël Reitsma, HRH Geology
In 2011, a borehole tar­geting nickel unexpect­edly discovered gas. The gas flowed from the hole with such force that it reportedly ‘screamed like a jet engine’ for four days un­til…
