Nature Energy, Published online: 18 June 2024; doi:10.1038/s41560-024-01554-2Investment in climate and energy (climate-tech) startups is growing in the US and worldwide, with public grants backing high-risk sectors and publicly funded startups exiting at higher rates with corporate investment. Public policies to incentivize corporate investment in these...

Nature Energy, Published online: 18 June 2024; doi:10.1038/s41560-024-01545-3Recent reforms of the EU Emissions Trading System (EU ETS) boosted carbon prices by tightening the cap on emission allowances and increasing political commitment to it, which effectively made actors more farsighted. Policymakers should thus view prices as an indicator of credibility...

Nature Energy, Published online: 18 June 2024; doi:10.1038/s41560-024-01555-1Zero-emission trucks will benefit from rapidly falling costs of batteries and fuel cells, which will enable their fast market diffusion. Industry and policy must prepare for battery-electric trucks with respect to their manufacturing and supply, adequate charging infrastructure...

Nature Energy, Published online: 12 June 2024; doi:10.1038/s41560-024-01557-zMolecular design is key to the power conversion efficiency in organic photovoltaics. Jiang, Sun, Xu et al. develop a non-fullerene acceptor with asymmetric structure and phenyl-substituted side chains that minimizes photon and carrier losses, enabling 20.2% efficiency.

Nature Energy, Published online: 11 June 2024; doi:10.1038/s41560-024-01556-0Graphene-based membranes are attractive for capturing CO2, with separation selectivity typically achieved by control of pore size. Here Hsu et al. incorporate pyridinic nitrogen species at the pore edges in graphene, leading to competitive CO2 binding and enhanced separation...

Nature Energy, Published online: 07 June 2024; doi:10.1038/s41560-024-01538-2Electrochemical ammonia (NH3) synthesis is a promising alternative to the Haber–Bosch process, but higher-performing systems are needed. Now, researchers realize long-term continuous NH3 electrosynthesis and production of high fractions of gas-phase NH3 by employing a chain...
