PROJECTS

Building a portfolio of geologic hydrogen opportunities

HyTerra is advancing a diversified portfolio of geologic hydrogen opportunities spanning multiple geological plays across the United States and internationally.

Our flagship Nemaha Project in Kansas provides a large, 100%-owned and operated position across multiple geological play types. Alongside our US portfolio, we are pursuing international opportunities in highly prospective regions such as Oman.

Our approach is focused on identifying the geological conditions capable of supporting commercial hydrogen accumulation and flow, using our proprietary “Hydrogen Must Haves” framework and the learnings generated through drilling, testing and detailed subsurface analysis.

HyTerra’s 100% owned and operated leases cover over 80,000 acres above the hydrogen-generating Mid-Continental Rift system.

Geneva Project (Nebraska) well testing results show hydrogen concentrations up to 44% and helium up to 13%^.

Leases are surrounded by important ammonia/fertilizer and helium production plants in the United States.

Kansas imports anhydrous ammonia from other U.S. states but is the USA’s largest helium producer.

Nemaha Project

Kansas, USA

Our flagship geologic hydrogen project

The Nemaha Project covers more than 80,000 acres in Kansas and is 100% owned and operated by HyTerra.

The project is strategically located close to potential offtakers including ammonia, helium and petrochemical facilities, with existing transport infrastructure in the surrounding region. It is also approximately 150km from McConnell Air Force Base.

Nemaha contains two geologically distinct areas of focus:

Ridge Play (Nemaha Ridge)

Rift Play (Mid-Continental Rift)

This multi-play portfolio provides HyTerra with multiple pathways to pursue geologic hydrogen potential within a single large-scale project.

White hydrogen. An abundant natural source.

White hydrogen is naturally occurring and, as such, could have much lower production costs and carbon emissions than hydrogen separated from natural gas or from water electrolysis.

At HyTerra’s Nemaha Project, rainwater seeps underground where it reacts with iron-rich rocks at elevated temperatures to make hydrogen (H2).

White hydrogen is brought to surface using conventional oil and gas techniques, and as an energy-dense, low carbon fuel source, it has the potential to revolutionise industry and economies worldwide.

Discover the wonders of hydrogen

Nemaha is also prospective for helium, a vital input for many technologies.

Helium is an irreplaceable input for many important technologies, with significant demand from manufacturers of semi-conductors to MRI’s.

A historic well drilled in 2009 at our Nemaha Project, Sue-Duroche-2 returned a helium occurrence of 3%*. The economic threshold for a helium-rich fields in U.S. is 0.3% for primary production.

Liquid helium sells at up to 50 times the price of LNG. Current prices are US$450/thousand standard cubic feet.

HyTerra continues to explore high-grade areas of significant helium potential.

^H2 + He % reflects occurrences of published gas analyses recovered from the wellbore. Uncertainty remains on historic well operations, sampling techniques, and analyses. The values are considered up to a % of H2 or He.

Company Profile

Our Geneva Project in Nebraska, USA, is targeting white hydrogen and helium.

HyTerra has a 16% interest (and the right to earn up to 51%) in a Joint Development Agreement with Natural Hydrogen Energy LLC for the Geneva Hydrogen Project near the town of Geneva in Nebraska, USA.

Drilled to 11,200ft (3,400m) in 2023, a wildcat well (Hoarty NE3) specifically targeted white hydrogen and was situated on the margin of a mid-continental rift. Elevated hydrogen was detected during drilling and gas was flared during swab testing.

The Company received gas composition data from Joint Development Agreement partner Natural Hydrogen Energy LLC (NH2E) in December 2024 and after independent review, HyTerra and NH2E reached a consensus that these analyses are valid in a joint meeting in March 2025.

Further assessment or appraisal operations (e.g. a new testing program due to the failure of the ESP) would be required to understand the potential for commercial hydrogen and/or helium production from this well. Discussions will continue with NH2E on the path forward for this venture.
