Ep68 - Geologic hydrogen: a possible renewable energy source in Zambales

Dr. Karmina Aquino reveals her groundbreaking study on geologic hydrogen in Zambales - a natural hydrogen gas released from rocks through water-rock interactions. Her research found one of the highest hydrogen outgassing rates ever measured globally. We also explore her path from geology to geochemistry, the role of ophiolites in hydrogen production, and the potential of geologic hydrogen as a future energy source for the Philippines.
