Swedish Researchers Supercharge Green Hydrogen Production
Sweden, Tuesday, 24 June 2025.
A new three-layer catalyst from Sweden boosts hydrogen production efficiency by eight times. This breakthrough could transform heavy transport by replacing fossil fuels with clean energy.
Revolutionary Triple-Layer Catalyst
Today, I’m thrilled to share that researchers in Sweden have unveiled a triple-layer catalyst, boosting the efficiency of hydrogen production by a staggering eight times. The technology, based on a composite of Ni(OH)₂/Co₃O₄/3C-SiC, significantly improves the sunlight-driven water-splitting process, a crucial step for producing green hydrogen. This advancement positions hydrogen as a key player for heavy transport, poised to reduce reliance on fossil fuels dramatically [1][2].
Boosting Heavy Transport
Imagine ships and airplanes powered by clean energy. With hydrogen emerging as a promising alternative, this development could transform industries that typically can’t use batteries due to weight concerns. As Associate Professor Jianwu Sun points out, electric batteries aren’t feasible for heavy trucks or aircraft, making these innovations in green hydrogen all the more crucial [1].
A Cleaner, Greener Future
Currently, most hydrogen is grey, derived from natural gas, and emits up to 10 tonnes of CO2 per tonne of hydrogen produced. In contrast, green hydrogen offers a zero-emission alternative, ushering a potential transition in the energy landscape. The enhanced efficiency of this catalyst brings commercial solar-to-hydrogen conversion closer to a viable reality, targeting a 10% efficiency crucial for economic viability [2][3].
Global Implications
‘This remarkable efficiency breakthrough inches us closer to practical implementation,’ predicts Jianwu Sun. He envisions the catalyst playing a vital role in achieving the EU’s 2035 goals of zero emissions from new vehicles. By addressing global energy challenges, such advancements foster a major shift toward sustainable energy solutions in sectors beyond just transportation [3].
The Road Ahead
With ongoing enhancements, commercialisation of this innovative material may occur within the next decade. The continuous funding and research efforts fuel hopes of further increasing efficiency and reducing material costs. It might not happen overnight, but the wind of change is definitely at our backs, clearing the path toward greener skies and seas [1][2].
