Para ilmuwan temukan sumber hidrogen alami di bebatuan Kanada

Para peneliti telah menemukan bahwa bebatuan purba di bawah Ontario secara alami memproduksi gas hidrogen dalam jumlah yang dapat diukur. Penemuan ini dapat menawarkan sumber energi bersih domestik baru bagi Kanada.

Para ilmuwan dari University of Toronto dan University of Ottawa mengukur hidrogen yang mengalir dari lubang bor di sebuah tambang aktif di dekat Timmins. Gas tersebut keluar dengan laju rata-rata 0,008 ton per tahun dari setiap lubang bor dan dapat terus berlangsung setidaknya selama satu dekade. Jika dihitung berdasarkan hampir 15.000 lubang bor di lokasi tersebut, totalnya mencapai lebih dari 140 ton setiap tahun, yang cukup untuk memberi daya bagi lebih dari 400 rumah setiap tahun dengan energi sebesar 4,7 juta kilowatt.

Researchers at ETH Zurich have engineered a catalyst using isolated indium atoms on hafnium oxide to convert CO2 and hydrogen into methanol more efficiently than previous methods. This single-atom design maximizes metal use and enables clearer study of reaction mechanisms. The breakthrough could support sustainable chemical production if powered by renewables.

Researchers have demonstrated in laboratory experiments that hydrogen can be produced from iron-rich rocks while simultaneously locking away carbon dioxide. The work, presented at a recent geoscience meeting, aims to combine clean energy generation with climate mitigation. Field trials are now being planned to test the approach at scale.

New research shows that melting glaciers in Greenland could free large quantities of methane trapped as hydrates beneath the ice. Scientists warn this process, observed after the last ice age, may repeat as the climate warms.

Scientists have found that the 2022 eruption of an underwater volcano in the South Pacific triggered a chemical process that removed significant amounts of methane from the atmosphere. The discovery, detailed in a new study, shows how volcanic ash and seawater combined to break down the potent greenhouse gas.
