A new pilot scheme at Nature Energy will enable authors to put data into a repository as part of their manuscript submission process.

One advantage of organic solar cells is that they can be fabricated by printing methods, yet the materials must be suitably designed. Now, Jiang et al. devise an alcohol-dispersed formulation of PEDOT with good wettability, solvent orthogonality and low acidity.

There has been continued debate on the cost and benefits of winterization of energy infrastructure in Texas, especially after 2021 power outages. Here the authors estimate the expected revenues from winterization, and its cost, and find that winterization would pay off taking into account the probability of similar outages.

Advanced nuclear reactors may lead to a significant reduction in the cost of nuclear energy. Duan et al. incorporate a wide range of potential advanced nuclear costs in their assessment of future decarbonization options and find areas where nuclear can support wind and solar.

Low effective doping of boron limits the performance of solar cells based on hydrogenated amorphous silicon. Liu et al. show that light induces the diffusion of hydrogen atoms, which activates boron doping, enabling a power conversion efficiency of over 25%.

Severe capacity decay at high voltages prevents the application of Ni-rich layered oxide cathodes. Here the authors report an electrolyte additive in a common commercial electrolyte that enables stable cycling at an ultra-high voltage of 4.8 V.

Metal–organic frameworks (MOFs) are promising candidates to store hydrogen for transportation, but less focus has been on their potential for storage in large-scale, stationary applications. Here Peng et al. perform techno-economic analysis and process modelling to evaluate the prospects of MOFs for back-up power.

Stable and high-power operation of aqueous redox flow batteries (ARFBs) is desirable for grid storage in cold climate regions. Here the authors report a heteropoly acid electrolyte with an exceptionally low freezing point and high conductivity that enables high-performance ARFBs at low temperatures.

Providing reliable, sustainable and clean energy in humanitarian contexts is increasingly important but a lack of data on settlements impedes progress. Here, Baldi et al. present a database and analytical tools for 288 refugee settlements in sub-Saharan Africa that can support renewable energy deployment decisions.

One advantage of organic solar cells is that they can be fabricated by printing methods, yet the materials must be suitably designed. Now, Jiang et al. devise an alcohol-dispersed formulation of PEDOT with good wettability, solvent orthogonality and low acidity.

Curbing subsidies to address inequalities only delays widespread and equitable adoption of rooftop solar, argues Eric O’Shaughnessy.

Money spent on Californian rooftop solar subsidies can be much better spent supporting more cost-efficient emission reduction measures, argues Severin Borenstein.
