Global carbon emissions from fossil fuels are projected to decrease by 0.4% in 2026 – driven by expansion of solar and wind power and the Iran conflict – according to new research by the Global Carbon Project.

Despite the dense solar wind, solar wind ion contributions to the ring current during the May 2024 superstorm were minimal — the first simultaneous observation of ring current ions and solar wind during a storm this large.

Data centres at the heart of the artificial intelligence (AI) revolution could be cooled more effectively and economically with a hybrid system under development at the University of Waterloo that targets hotspots on computer chips with a single drop of boiling coolant.

The UK has seen great progress toward decarbonisation with 63% of electricity now low-carbon, especially thanks to wind and nuclear, supported by hydro, solar and biomass.

Norway has the technology and expertise needed to develop high-speed catamarans capable of operating even the longest routes. But something is missing.

A collaboration between researchers at Cornell and City University of Hong Kong has produced a new computational tool that could help overcome one surprisingly persistent obstacle to the efficient production of so-called green hydrogen: bubbles.

Green hydrogen, produced by splitting water using electricity from renewable sources, offers a promising alternative to fossil fuels, particularly for industries such as steelmaking and chemical manufacturing.

The researchers developed a computer model that reveals how bubbles forming during water electrolysis interfere with the process and increase the energy required to produce hydrogen. Their findings, published Nov. 9 in the journal EES Catalysis, identify a critical bubble size beyond which energy losses increase dramatically, providing a potential roadmap for designing more efficient hydrogen-producing equipment.
