Mitigation of hydrogen crossover in liquid alkaline water electrolysers using gas recombination catalysts - Nature Energy

Alkaline water electrolysers are being optimized for higher performance, but measures such as advanced electrodes or thinner separators can increase hydrogen crossover and safety risks. Here the authors analyse crossover behaviour and show that a gas recombination catalyst cuts crossover by 95% without affecting electrolyser performance.

Understanding interconnected ion and water transport in anion exchange membrane zero-gap CO2 electrolysers - Nature Energy

Achieving long-term stability in low-temperature anion exchange membrane zero-gap CO2 electrolysers is hindered by salt precipitation and flooding, which limit CO2 transport. In this Perspective, the authors explore the interplay between ion and water transport processes, emphasizing the need for strategies to simultaneously manage both to extend cell runtimes.

Batteries versus fuel cells for decarbonizing medium- and heavy-duty vehicles across applications - Nature Energy

Decarbonizing medium- and heavy-duty vehicles is challenging, and the relative benefits of batteries versus fuel cells remain uncertain across applications. This modelling work shows that both reduce emissions versus diesel, but battery electric vehicles powered by renewable electricity deliver the lowest life-cycle greenhouse gas emissions in most cases.

Ambient-pressure conversion of plastic waste to jet fuel cycloalkanes by tandem hydropyrolysis and vapour-phase hydrogenation - Nature Energy

Converting plastic waste into jet fuel could support aviation decarbonization, but current approaches are limited by high-pressure requirements and low efficiency. Here the authors present a tandem hydropyrolysis and vapour-phase hydrogenation strategy that uses a Ru/Co-Al oxide catalyst, achieving promising rates and yields at low pressures.
