Li metal batteries offer much hope for the future of high-energy storage systems. Albertus et al. survey the current status of research and commercial efforts, and discuss key metrics and measurements as well as cost issues in enabling high-performing lithium metal electrodes.
The UN’s Agenda for Sustainable Development has 17 goals with 169 targets for action across a range of issues, with access to sustainable energy for all being Goal 7. This Perspective analyses interlinkages between energy systems, Goal 7 and the other goals at the target level, identifying synergies and trade-offs between them.
A policy sequence for low-carbon policy that is politically effective continues to face challenges of environmental and cost effectiveness. This Perspective outlines ways to address these issues within political constraints.
The Eastring gas pipeline intends to connect Slovakia with southern and eastern European states in light of other infrastructural changes in the region. Misik and Nosko argue that neither perceived loss of energy security nor loss of rents from gas transit should be the main drivers behind the project.
Urban households in the global south face unique energy access challenges. This Perspective outlines a research agenda based on understanding the needs of urban energy users to promote inclusive urban energy transitions.
Despite being currently under-represented in IPCC reports, PV generation represents a growing share of power generation. This Perspective argues that underestimating PV potential led to suboptimal integration measures and that specific deployment strategies for emerging economies should be developed.
Heterostructures with alternating layers of different 2D materials are finding increasing attention in energy applications. Pomerantseva and Gogotsi survey the opportunities and challenges of both developing the heterostructures and their implementation in energy storage devices.
