The Southeast Asian nation reportedly has the largest natural hydrogen seeps anywhere on Earth, indicating that huge volumes of hydrogen could be stored under the ground, waiting to be exploited. The problem is that hydrogen is only as green as the methods used to make it, and green hydrogen – produced using clean energies – simply can’t compete economically with gray hydrogen, which is made using fossil fuels. Geologic hydrogen could sidestep these issues by sourcing natural hydrogen directly from the Earth. That represents an enormous savings compared to the current green hydrogen cost of approximately $3.50–$6.00 per kilogram. “The Philippines has the largest natural hydrogen seeps anywhere on the planet,” Koloma CEO Pete Johnson recently told Forbes.
