Hoarty NE3 — Nebraska

Hoarty NE3 — First U.S. Natural Hydrogen Wildcatter Well, Fillmore County, Nebraska

The proof event that changed Larin Energy from thesis to platform.

In 2019, the Hoarty NE3 well in Fillmore County, Nebraska validated the Larin scientific framework in the field — returning 44% H₂ in produced gas samples and establishing the first U.S. wildcatter natural hydrogen proof event.

Why It Mattered

Hoarty NE3 is not just a project. It is the company's origin proof event.

Hoarty NE3 was drilled and managed by Larin Energy through its subsidiary, Natural Hydrogen Energy LLC. HyTerra Ltd. (ASX: HYT) holds a 16% joint venture interest — an independently listed ASX company whose own disclosures corroborate the results.

Before Hoarty NE3, natural hydrogen exploration in the United States was theoretical. The Hoarty NE3 well changed that. It demonstrated that the scientific framework advanced by V.N. Larin and V.M. Shestopalov — applied to real geological structures — could produce measurable, verifiable results at concentrations with genuine commercial and strategic significance.

Request Investment Summary →
A dual-commodity system, not a single-gas story
Hoarty NE3 returned hydrogen concentrations that exceed commonly cited commercial benchmarks — 44% H₂ in produced gas, above the commercial viability threshold identified in peer-reviewed techno-economic analysis. At Hoarty NE3, helium was also present at commercially significant concentrations — a co-product specific to this site's geological conditions, and not a feature of every natural hydrogen system. View independent lab report →
Science translated into field execution
The well was not drilled opportunistically. It was located, targeted, and drilled using the Larin & Shestopalov exploration methodology — fault and migration pathway analysis applied to a specific structural thesis. Hoarty NE3 confirms the methodology produces locatable targets.
The foundation for everything that follows
Every project in Larin Energy's current portfolio is built on the geological logic that Hoarty NE3 validated. The company's commercialization strategy — hydrogen to power — runs through this proof event as its origin.
Benchmark Context

Hoarty NE3 findings vs. public performance thresholds

Measured against peer-reviewed commercial viability thresholds for natural geologic hydrogen and USGS/National Academies helium commercial thresholds — two independently established benchmarks for subsurface gas concentrations.

Hydrogen — H₂
Commercial Viability Threshold
>40%
wellhead purity
Hoarty NE3 Result
44%
Above commercial viability threshold
Peer-reviewed techno-economic analysis identifies >40% wellhead purity as the minimum required for natural geologic hydrogen to achieve commercial viability (<$1/kg at wellhead). Hoarty NE3 returned 44% — above that threshold.
Helium — He
Economic Threshold
~0.3%
commercial viability
Hoarty NE3 Result
12.8%
~40× the economic threshold
USGS and National Academies sources commonly cite ~0.3% helium as a commercial threshold — Hoarty NE3's result sits approximately 40× above that line. Helium co-occurrence is geology-dependent, confirmed at this site but not guaranteed at every natural hydrogen system.

Publicly Reported Benchmarks

Program Timeline

From scientific thesis to field proof to platform

The Hoarty NE3 program followed a disciplined sequence — from geological thesis through structural targeting, permitting, drilling, and verification — that is now the operational template for Larin Energy's broader portfolio.

Pre-2019
Geological thesis and target identification
Larin & Shestopalov exploration methodology applied to Nebraska basin. Fault and migration pathway analysis identifies Hoarty NE3 as a priority structural target.
2018–2019
Permitting and well planning
Surface and subsurface data integration completed. Hoarty NE3 location finalized. Nebraska wildcatter drilling permits secured.
2019
Hoarty NE3 drilled at Hoarty NE3
First U.S. wildcatter hydrogen well. Hoarty NE3 penetrates target formation at Fillmore County, Nebraska.
2019
Gas sampling — initial results
Produced gas samples return 44% H₂ — above the commercial viability threshold for natural geologic hydrogen. Helium also measured at 12.8% at this site. Samples submitted for independent verification.
2019
Independent verification confirmed
44% H₂ concentration independently verified. Helium concentration of 12.8% also confirmed — a co-product present at Hoarty NE3's geological setting. Hoarty NE3 established as Larin Energy's origin proof event. View independent lab report →
Ongoing
Portfolio expansion anchored on Hoarty NE3
The geological framework validated at Hoarty NE3 is applied to new basin targets in Texas, California & Michigan. Active appraisal program continues.

02 Techno-economic analysis of natural and stimulated geological hydrogen — International Journal of Hydrogen Energy, 2025

Peer-reviewed techno-economic analysis of natural geologic hydrogen (GH) production economics. Detailed sensitivity analysis identifies wellhead gas purity and production flow rate as the primary cost drivers. Findings establish that natural GH requires wellhead purity above 40% to achieve commercial viability (<$1/kg at wellhead) — the threshold against which the Hoarty NE3 result of 44% H₂ is benchmarked.

03 USGS / National Academies — Helium Resources: Commercial and Economic Threshold Analysis

USGS and National Academies publications commonly describe approximately 0.3% helium concentration as a commercial/economic threshold for helium-bearing natural gas systems. Hoarty NE3's independently verified result of 12.8% He is approximately 40× above this threshold.

Third-party laboratory analyses independently confirm the gas concentrations returned by the Hoarty NE3 wellbore: 44.02% hydrogen (Job 54092, isotopic analysis) and 12.80% helium (Job 50745). These reports are independently commissioned and constitute the primary evidentiary basis for the results cited on this page. View lab reports in the Resources section →

Where helium co-occurs with hydrogen — as at Hoarty NE3 — it may provide a secondary revenue stream, subject to separation and market conditions. Co-occurrence is geology-dependent and represents upside potential, not a guaranteed feature of every site.
