On the potential of vehicle-to-grid and second-life batteries to provide energy and material security
Europe is becoming increasingly dependent on battery material imports. Here, authors show that electric vehicle batteries could fully cover Europe’s need for stationary battery storage by 2040, through either vehicle-to-grid or second-life-batteries, and reduce battery material demand by up to 7.5%.

Dual water-electricity cooperation improves economic benefits and water equality in the Lancang-Mekong River Basin
Li and colleagues develop a dual water-electricity cooperation (DWEC) framework that combines water and electricity trading to meet the often-conflicting demands of participating countries in the Lancang-Mekong river basin. They discuss the potential of this framework for application in other transboundary river systems.

The impact of methane leakage on the role of natural gas in the European energy transition
Cost-optimal European energy transition with CO2 and methane neutrality objective is studied. While renewables are the key drivers of climate neutrality, the continuous role of natural gas requires high levels of both CO2 and methane abatement.

Endogenous learning for green hydrogen in a sector-coupled energy model for Europe
This study highlights the importance of including learning-by-doing for hydrogen production in energy models. It reveals that scaling up renewable capacities and electrolysis faster than the EU’s REPowerEU Plan can be cost-effective under strict climate targets, reducing hydrogen production costs and shifting from grey to green hydrogen.

U.S. West Coast droughts and heat waves exacerbate pollution inequality and can evade emission control policies
Heat waves and droughts increase air pollution from power plants in California, which disproportionately damages counties with a majority of people of color. Droughts cause chronic increases in pollution damages. Heat waves are responsible for the days with the highest damages.

Unveiling hidden energy poverty using the energy equity gap
In the summer, low-income households in the Arizona, US wait 4 - 7 °F (2.6–4.2 °C) longer than high-income households to turn on their AC units to save money on energy bills. This energy limiting behavior indicates a hidden form of energy poverty.

Plant conversions and abatement technologies cannot prevent stranding of power plant assets in 2 °C scenarios
Many existing and in-the-pipeline fossil-fuel power plants will have to be decommissioned or underused to avoid climate change beyond 2 °C, even under optimistic technology assumptions and after accounting for emission-reducing conversions.

Ultra-selective molecular-sieving gas separation membranes enabled by multi-covalent-crosslinking of microporous polymer blends
Microporous polymers become increasingly attractive as materials for the fabrication of permeable and selective gas separation membranes but separation performance is often limited by broad pore size distribution. Here, the authors design a porous polymer membrane via multi-crosslinking of miscible blends of microporous polymers enabling simultaneous high permeability and selectivity.

Emission impacts of China’s solid waste import ban and COVID-19 in the copper supply chain
Advanced copper supply chain modeling shows China’s new waste trade policy may increase pollution, while limiting other low-value imports reverses this trend. Here the authors show that recycling is vulnerable to supply chain shocks, requiring investment during recoveries to promote a circular economy.

Adsorption of rare earth elements in regolith-hosted clay deposits
Global resources of heavy Rare Earth Elements (REE) are dominantly sourced from Chinese regolith-hosted ion-adsorption deposits, yet the adsorption mechanisms remain unclear. Here, the authors find that heavy REE are adsorbed as easily leachable 8-coordinated outer-sphere hydrated complexes, dominantly onto kaolinite, in clays from both China and Madagascar.

The impacts of power plant water shortage during drought on electricity prices are understudied. Here the authors show that on extreme days, almost 50% (7 GWe) of the freshwater thermal capacity is unavailable in the Great Britain and annualized cumulative costs on electricity prices are in the range of £29-95m per year.
