Synthesizing ammonia electrochemically from N2 could help to decarbonize production of this important chemical and potential energy carrier. In recent years, a Li-mediated process has been shown to be effective for ammonia synthesis. In this approach, it is generally believed that when a voltage is applied, Li(I) is reduced to Li metal at the cathode, reacting with N2 to form nitrides; the nitrides

The tunnel oxide passivated contact (TOPCon) silicon solar cell is a technology that is gaining traction in the photovoltaic industry due to high performance and competitive manufacturing costs. Yet given the relatively recent development of the technology, its reliability under operational conditions is not yet fully understood. In particular, TOPCon solar cells have been reported to be susceptible

Nature Energy talks to Sheila Oparaocha (pictured), Director of the ENERGIA International Network on Gender and Sustainable Energy, and Magi Matinga, Technical Advisor at ENERGIA, about challenges and opportunities for ensuring gender equality in Africa’s energy transition, and how well aligned the fields of advocacy, policy and research are on this issue.

Salvatore Finamore speaks with Nature Energy about what the Analysis and Research Team at the Council of the European Union does and how they measure impact, while offering insight for researchers looking to reach a policy audience.

Understanding the mechanisms of improvements in energy technologies can inform efforts to drive further innovation. Now, researchers evaluate the role of research and development, along with technology spillovers, in the improvement of light-emitting diodes.

As distributed energy resources (DERs) such as solar photovoltaics and battery storage grow in popularity at the consumer level, their proportional role in electricity grids is also increasing. Globally, companies have introduced rules surrounding DER integration. However, circumvention of formal processes is not uncommon, with instances of unauthorized DERs noted in many countries, posing challenges

Compared to conventional metal oxide cathodes found in Li-ion batteries, Li-rich layered oxides introduce an additional charge storage mechanism that involves not just transition metals, but also lattice oxygen, known as anionic redox. These dual (cationic and anionic) redox processes enhance Li-ion utilization and increase capacity, making these materials promising candidates for next-generation batteries

Electrocatalysts based on ruthenium are very active for water oxidation (the reaction that occurs at the anode of an electrolyser) but typically suffer from poor stability. In the harsh acidic and oxidative conditions found at the anode of a proton exchange membrane electrolyser, metal ions can leach out of the catalyst and structural collapse may occur, leading to reduced performance. Now, Zhanwu

Perovskite solar cells have demonstrated high power conversion efficiency, yet their stability under realistic conditions remains to be convincingly demonstrated. One critical step in addressing the issue is the development of accelerated ageing tests (that is, use of higher stress levels than in real-world conditions) that can reproduce in the laboratory the failure modes observed in the field. It

Llewelyn Hughes is a social scientist working on the low-carbon energy transition, with a particular focus on the Asia-Pacific region, and Professor at the Crawford School of Public Policy at the Australian National University. He talks to Nature Energy about evolving trade relationships and interdependencies in the energy transition, and the role of social sciences research in informing policy in

The City of Los Angeles (LA) has committed to reaching a 100% renewable, equitable electricity grid by the year 2035, and in 2021 the city released the LA100 study1, which established the feasibility of local grid decarbonization pathways. This study emphasized that only explicitly justice-oriented strategies2 would ensure equity outcomes. As a result, LA100 was followed by the LA100 Equity Strategies

Lithium metal batteries (LMBs) offer high energy density and power capability but face commercialization challenges primarily due to limited cycling stability and safety concerns. Notably, asymmetric cycling operation, that is slow charging and fast discharging, has shown potential benefits in improving cycling stability. However, the underlying mechanisms of Li deposition behaviour, the formation

Aqueous amines can be used to capture CO2 from flue gas. However, under the conditions used in the CO2 ‘scrubbing’ process, amines are susceptible to thermal and oxidative degradation into a variety of products, meaning that procedures to reclaim and replace them are needed to maintain carbon capture performance. Identification of alternative carbon capture molecules with greater stability could thus

Renewable energy projects that fail to account for the concerns of impacted communities run the risk of lowered public acceptance and criticism. As a result, participatory approaches to these projects are increasingly gaining traction. Renewable energy cooperatives (REScoops) are one way to include local citizens in project development and decision making. Although such projects are becoming popular
