In the sea area around Hokkaido, the existence of bottom simulating reflectors (BSR) has been confirmed off Abashiri, Okushiri Island, Hidaka, and Tokachi. In November 2020, we succeeded in collecting methane hydrate present in the surface layer of the seafloor in the Pacific Ocean off Tokachi. Attempts a direct reforming methane dissociated from the methane hydrate, was successfully hydrogen generation by a chemical reaction that does not generate carbon dioxide. In addition, carbon could be recovered as carbon nanotubes with high utility value.
