Hydrogen Production Potential Indicated by Philippine Native Hydrogen Survey

US-based Koloma, Inc. has begun a two-dimensional seismic survey in Pangasinan, Philippines, the Philippine Department of Energy says. According to the DOE, seismic lines are being combined with nearly 28,000 line-kilometres of earlier airborne gravity and magnetic measurements to map subsurface structures that could host native hydrogen. Koloma holds Service Contract 84 in Pangasinan and Service Contract 83 in adjacent Zambales, and under the DOE’s framework the company bears all technical and financial risks.

The seismic programme follows geological sampling at the Los Fuegos Eternos natural-gas seep area and the acquisition this year of 27,976.5 line-kilometres of gravity and magnetic data. Energy Secretary Sharon S. Garin said this month that the combined survey and sampling results point to promising indications of geologic hydrogen in target formations, while stressing that further drilling and commercial-viability assessments are necessary before any production claims can be made.

Mapping the Subsurface

Airborne gravity and magnetic surveys first highlighted variations in rock density and magnetic properties, the DOE notes. These maps helped interpreters locate iron-rich ophiolitic bodies where water-rock reactions may generate hydrogen. The new 2D seismic line-kilometre programme then sends acoustic waves into the ground. Surface receivers capture reflections that sketch subsurface layers, faults and traps.

Koloma has also indicated plans to deploy magnetotelluric surveying, which measures the Earth’s natural electromagnetic signals to reveal deeper conductivity contrasts. The company describes this multi-method approach as an adaptation of oil and gas exploration tools to hydrogen’s peculiar behaviour, which can dissolve into fluids or escape via microfractures. In practice that means structural closure and seal integrity become especially critical when selecting targets.

Data Interpretation Challenges

Interpreting geophysical anomalies for hydrogen is not the same as for hydrocarbons, the DOE guidance and Koloma’s technical team say. Hydrogen’s lower acoustic impedance and high diffusivity can produce weaker seismic reflections and scattered signals, requiring bespoke processing workflows. Analysts must also separate potential hydrogen-related features from water-filled fractures, mineral variations or cultural noise.

Koloma says its proprietary datasets and machine-learning models correlate gravity, magnetic and seismic signatures with geochemical sampling. Independent specialists, however, caution that applying these methods across varied ophiolite environments remains untested. To refine its framework, the company is cross-referencing field measurements with global natural hydrogen case studies.

Scientific Foundation

Natural hydrogen seeps in the Zambales ophiolite have long attracted scientific interest. Researchers from the Philippine Nuclear Research Institute reported that the Nagsasa seep released roughly 808 tonnes of hydrogen per year at the surface, underscoring active water-rock reactions. PNRI scientists warn, though, that surface flux measurements alone cannot establish underground reservoir size, pressure or flow rates—parameters that are critical to commercial production.

The British Geological Survey, working with PNRI and the GFZ Helmholtz Centre for Geosciences, has performed atomic-scale experiments at Diamond Light Source to study how water interacts with ultramafic minerals to generate hydrogen. BGS experts emphasize remaining uncertainties about migration pathways, microfracture networks and whether accumulations are continuous at depths relevant to a producing field.

Policy and Costs

The DOE incorporated native hydrogen into its energy-service-contract regime under Department Circular No. DC2023-11-0031, creating the country’s first formal bidding framework for the resource. Under that regime, contractors such as Koloma assume all exploration costs; the agency says there is no direct government funding. Philippine news outlets report that Koloma’s combined exploration programme—including seismic, gravity and magnetic surveys and planned drilling—carries a price tag of roughly $8–9 million. The DOE clarifies that those figures are company-reported and not independently audited.

Drilling the Questions

Geophysical surveys can indicate traps and plausible targets, but only drill cores and test wells can confirm gas presence, pressure and flow behaviour. Koloma plans to drill stratigraphic wells first to gather rock, fluid and gas samples. If initial targets look promising, the company intends deeper exploration wells.

These drilling steps will determine whether any accumulation is continuous, pressurized and sufficiently productive to warrant commercial development. They will also reveal whether hydrogen is present in concentrations and flow regimes compatible with infrastructure and market demands.

Industry Ripples

A confirmed domestic source of native hydrogen could diversify the Philippines’ energy mix beyond imported fuels and industrially produced green hydrogen. A commercial field would create demand for local geoscience services, drilling contractors and laboratory analysis. It could also stimulate a downstream market for hydrogen infrastructure—pipelines, storage and refuelling stations among them.

Koloma’s programme also builds in-country expertise in airborne geophysics, seismic interpretation and hydrogen-specific regulation—capabilities that may have spillover benefits for geothermal, natural gas or mineral exploration projects. Reports indicate Koloma is pursuing applications for two additional native-hydrogen service contracts, which would broaden its acreage in Central Luzon and Zambales pending DOE approval. Investors and competitors are likely to watch drilling results closely; success could prompt new bidding rounds under the DOE’s native hydrogen policy.

Global Comparisons

The Philippines is among the first jurisdictions to award competitive service contracts specifically for native hydrogen exploration, a framework the DOE says is intended to attract technology-focused investors. Elsewhere, natural hydrogen remains at an early, primarily scientific stage, with pilot surveys in Europe and Australia. Observers note that the outcomes of the Philippine programme could influence international regulatory approaches and investment decisions in geologic hydrogen exploration.

Environmental Lens

Native hydrogen extraction might offer a lower-carbon option if the energy inputs required for exploration and production are modest. Lifecycle emissions, however, will hinge on drilling power sources, water use and any methane co-production. The DOE framework mandates environmental oversight, yet independent analyses caution against assuming zero-emission outcomes without detailed gas-composition data and full accounting for surface disturbance and fugitive gases.

A Look Ahead

The current seismic survey marks a shift from scientific observation toward commercial-style exploration in the Philippines’ early native hydrogen programme. Whether preliminary indications translate into a producing field depends on drilling outcomes, reservoir behaviour and cost competitiveness versus manufactured hydrogen. For now, the project underscores a broader question being asked by explorers globally: can unmanufactured, geologic hydrogen join natural gas and geothermal as a domestic, lower-carbon energy resource?
