Direct air capture is an emerging technology to decrease atmospheric CO2 levels, but it is currently costly and the long-term consequences of CO2 storage are uncertain. An alternative approach is to utilize atmospheric CO2 on-site to produce value-added renewable fuels, but current CO2 utilization technologies predominantly require a concentrated CO2 feed or high temperature. Here we report a gas-phase dual-bed direct air carbon capture and utilization flow reactor that produces syngas (CO + H2) through on-site utilization of air-captured CO2 using light without requiring high temperature or pressure. The reactor consists of a bed of solid silica-amine adsorbent to capture aerobic CO2 and produce CO2-free air; concentrated light is used to release the captured CO2 and convert it to syngas over a bed of a silica/alumina-titania-cobalt bis(terpyridine) molecular–semiconductor photocatalyst. We use the oxidation of depolymerized poly(ethylene terephthalate) plastics as the counter-reaction. We envision this technology to operate in a diurnal fashion where CO2 is captured during night-time and converted to syngas under concentrated sunlight during the day.

The performance of kesterite solar cells is limited by poor extraction of electrons and holes and their recombination. Researchers have now discovered that annealing the device in a hydrogen-containing atmosphere can promote efficient charge extraction by redistributing certain elements like sodium and oxygen.

Improving the solid–electrolyte interface at the lithium-metal interface is key to stabilizing rechargeable metal batteries. Now, stabilizing the cathode electrolyte interface through molecular optimization of the salt anion is shown to support the formation of a robust inorganic polymer and conductive interface, enabling high energy and power densities at various current densities and temperatures.

Decarbonization of energy-using sectors is essential for tackling climate change. We use an ensemble of global integrated assessment models to assess CO2 emissions reduction potentials in buildings and transport, accounting for system interactions. We focus on three intervention strategies with distinct emphases: reducing or changing activity, improving technological efficiency and electrifying energy end use. We find that these strategies can reduce emissions by 51–85% in buildings and 37–91% in transport by 2050 relative to a current policies scenario (ranges indicate model variability). Electrification has the largest potential for direct emissions reductions in both sectors. Interactions between the policies and measures that comprise the three strategies have a modest overall effect on mitigation potentials. However, combining different strategies is strongly beneficial from an energy system perspective as lower electricity demand reduces the need for costly supply-side investments and infrastructure.

Observations of salt formation in CO2 reduction electrolysers were used to propose a mechanism for salt precipitation linked to the drying of liquid droplets carrying cations and (bi)carbonate ions. A hydrophobic surface coating was used to remove droplets from the flow channels before they can dry, increasing the operational stability of the electrolyser.
