Un grupo de investigadores ha descubierto que rocas milenarias bajo Ontario producen gas hidrógeno de forma natural en cantidades medibles. Este hallazgo podría ofrecer a Canadá una nueva fuente nacional de energía limpia.

Científicos de la Universidad de Toronto y la Universidad de Ottawa midieron el flujo de hidrógeno proveniente de perforaciones en una mina activa cerca de Timmins. El gas se libera a un ritmo promedio de 0,008 toneladas por año por cada perforación y puede continuar haciéndolo durante al menos una década. Si se extrapola a las casi 15.000 perforaciones del lugar, el total alcanza más de 140 toneladas anuales, cantidad suficiente para abastecer más de 400 hogares cada año con 4,7 millones de kilovatios de energía.

Scientists develop single-atom catalyst for CO2-to-methanol conversion

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.

Lab tests show hydrogen can be made from rocks while storing CO2

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.

Greenland ice melt may release vast methane stores

Volcanic plume unexpectedly destroyed methane after 2022 eruption

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.

Scientists develop sunlight method to convert plastic waste into hydrogen

4 de mayo de 2026 Reportado por IA

Researchers at the University of Adelaide have devised a solar-powered process to transform plastic waste into clean hydrogen fuel and other chemicals. The technique, known as solar-driven photoreforming, uses sunlight and photocatalysts to break down plastics at low temperatures. Early experiments show promising hydrogen yields and system stability.
