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.⌛Chapters00:00 Starting the Geologic Hydrogen Conversation00:55 Podcast and Partners Introduction04:10 A Scientist’s Journey08:46 Geochemistry and Ophiolites Review12:05 Understanding Geologic Hydrogen15:08 Hydrogen Outgassing Review in Zambales18:02 Zambales Study Results and Information33:36 Geologic Hydrogen Studies36:36 Hydrogen Applications in Energy41:17 Fieldwork and Communication Challenges51:16 Fieldwork Experiences58:47 Ongoing Projects and Scholarships📚Reference: Aquino, K.
