EU green hydrogen policies could be more effective if they accounted for spatial spillovers. These spillovers are a primary driver of diffusion, and spatially informed demand-side policies could improve cost-effectiveness by up to 41%.

Realized green hydrogen demand lags behind policy targets but could be accelerated by accounting for spatial spillovers, which refer to demand-side interdependencies where adoption by one user encourages further adoption by nearby users. Revising EU green hydrogen policies, including Hydrogen Valleys and European Hydrogen Bank auctions, to better account for these location-specific demand-side patterns could improve their effectiveness.

Seawater is an attractive feedstock for hydrogen production that overcomes community concerns about fresh water; however, electrolysis of seawater remains challenging. Now, a coupled alkaline water electrolysis and vacuum distillation in a unified process overcomes those challenges by using waste heat to treat seawater, enabling 250 kW-scale efficient co-production of hydrogen and fresh water.

Given its abundance, seawater is an attractive feedstock for hydrogen production, but direct electrolysis is hindered by side reactions and corrosion. Here the authors couple alkaline electrolysis with low-temperature desalination, using waste electrolyser heat to distil seawater into a fresh water feed, enabling stable, scalable performance.

Hydrogen pipelines could become important for future energy systems, but current cost estimates often ignore regional differences. This study develops a more realistic approach that accounts for geography, infrastructure and financing factors to improve hydrogen transport cost assessments.

Solid electrolytes have long been treated as materials that block electronic conduction while enabling fast lithium-ion transport. Two studies now show that residual electronic conductivity can drive self-discharge in solid-state batteries at open circuit, particularly in thin practical cells, and identify the limits needed to ensure long shelf life.

Lithium-sulfur batteries have long been limited by lower operating voltage and shorter lifetime compared to traditional lithium-ion technologies. Now, system-level engineering enables the conversion of sulfur to disulfur dichloride, accessing the S+1 oxidation state, thereby delivering higher voltage and improved cycling stability.
