The Philippines is advancing early-stage exploration into natural hydrogen, with U.S.-based startup Koloma, Inc. preparing to study potential reserves in Luzon.
According to Energy Secretary Sharon Garin, the company has secured approval to explore two sites in Zambales, marking what could become the country’s first formal hydrogen exploration project.
The Department of Science and Technology (DOST) previously identified Nagsasa Cove in San Antonio, Zambales, as a potential hydrogen-rich area, with surface gas seeps estimated at around 808 metric tons. However, the volume represents only surface-level emissions; whether viable reservoirs exist underground remains unproven. Koloma’s involvement reflects growing international interest in hydrogen as a long-term energy source, though the commercial pathway—from exploration to drilling, storage, and conversion—could span a decade.
Hydrogen exploration remains uncharted territory for the Philippines, where energy security challenges are dominated by reliance on imported fossil fuels and the aging Malampaya gas field, the country’s sole major domestic source. Garin noted that Koloma has expressed interest in securing additional contracts in Luzon, with the Department of Energy (DOE) aiming to finalize the first exploration agreement within the year. At the same time, six foreign and three local firms have submitted broader proposals to explore petroleum and hydrogen resources, including companies from Saudi Arabia.
Yet, significant risks shadow these ambitions. Hydrogen itself poses challenges due to its instability in transport and storage, requiring technologies that remain under development. Beyond technical barriers, geopolitical tensions in the West Philippine Sea (WPS) could deter investment. Manila has previously suspended exploration in contested waters, most notably under the 2014 moratorium imposed during President Benigno Aquino III’s administration. Garin acknowledged investor hesitancy tied to security risks, citing the need for heavy protection at Malampaya as an example of the environment developers may face.
