The Department of Energy (DOE) has completed a reconnaissance survey in Palawan to explore the potential of a natural low-carbon energy source, also known as “white hydrogen”.

The DOE said the survey, held from August 12 to 15, marked the second leg of its nationwide program to assess the Philippines’ hydrogen resources across nine ophiolite belts. A joint technical team from the Energy Resource Development Bureau (ERDB) and the Energy Research and Testing Laboratory Services (ERTLS) collected water, gas, and rock samples from hot springs and outcrops in the municipalities of Sofronio Española and Narra, as well as in Puerto Princesa City.

Initial results from sites such as Kay’s Hot Spring in Sta. Lourdes, Puerto Princesa, and Bato-Bato Hot Spring in Calategas, Narra, showed promising indicators of naturally occurring hydrogen. According to the DOE, the findings highlight Palawan’s potential to play a bigger role in the Philippines’ clean energy transition, alongside initiatives such as the long-established Malampaya project.

The activity was carried out with the support of the Mines and Geosciences Bureau (MGB) MIMAROPA, the Palawan Council for Sustainable Development (PCSD), and local government units, all of which provided assistance throughout the survey. The samples are set to undergo laboratory analysis to determine their potential and guide future strategies on harnessing indigenous clean energy resources.

This was the DOE’s second hydrogen survey, following a study in Zambales and Pangasinan from June 30 to July 4. That first survey, which included the Mangatarem Hot Spring in Pangasinan and the Botolan Hot Spring in Zambales, covered areas under predetermined contract blocks offered in the 2024 Philippine Bid Round. It provided baseline geological and environmental data to support service contractors in guiding exploration activities, helping determine priority areas and appropriate methodologies for clean energy development.

The two surveys form part of preparatory groundwork for the Philippines’ first specialized training on native hydrogen exploration, which will bring together local and international experts later this year.

Through these initiatives, the DOE said it reaffirms its commitment to “unlocking new indigenous energy frontiers, advancing scientific knowledge, and fueling a sustainable future for the Filipino people.”

With Palawan now at the center of this pioneering effort, the question remains: could white hydrogen be the Philippines’ next great energy breakthrough?
