Summary: In order to reduce greenhouse gas emissions, countries must increase the use of renewable energies, which require more land area. The concept of power density can assist in decision-making for resource allocation. Bioenergy plays a key role in the energy transition, with power densities for biomass types generally higher than those for fossil fuels.

Summary: The COVID-19 pandemic has had detrimental effects on hydrocarbon-dependent Gulf states, threatening their long-term economic sustainability. The weakened economic resilience caused by the previous oil price collapse and government responses has hindered their ability to fully benefit from COVID-relief packages. The current economic structure and consumption-based nature of the relief packages also impede their economic transitions.

Summary: Alloying metals can significantly alter their characteristics. Nanoalloy electrodes are excellent materials for bridging supercapacitors and batteries. We present an ultra-small bimetallic CoNi nanoalloy functionalized on 2D graphitic nitride (g-C3N4) sheets via hydrogenation. The CoNi@g-C3N4 nanoalloy asymmetric supercapacitor, fabricated with activated carbon nanofiber (ACF), exhibits a wide potential window of 1.5 V and an excellent life span of 8000 cycles at an ultra-high current density of 15 A g-1. Furthermore, operating the cell at different temperatures (2 °C, RT, 50 °C, and 65 °C) shows an enhanced energy density of 26 Wh kg-1 at 50 °C compared to a lower temperature (2 °C) of 15 Wh kg-1.

Summary: The Ragone plot is widely used in studying power and energy density for batteries, fuel cells, and other energy conversion technologies, especially in transportation and mobile applications where weight is a key limiting factor. By optimizing the geometry of thermoelectric legs, the highest power and energy densities can scale nearly with the square root of the material figure-of-merit (ZT). Internal heat recovery technology can significantly increase fuel economy.

Summary: This study identifies 14 decarbonisation strategies for the oil and gas supply chain through literature review and ranks them using decision-making methods. The results reveal that CO2 flooding technology in the upstream, renewable energy integration for transport in the midstream, and carbon capture, utilisation, and storage systems in the downstream are the most effective strategies for decarbonising the supply chain.

Summary: Two-dimensional MXenes are efficient electrochemical capacitors with high energy and power densities. V2CTx MXene, as one of the lightest members, is limited in its effective use due to restacking. A composite of ZrO2-MXene was reported, where ZrO2 nanparticles were grown on V2CTx MXene sheets. The interconnected structure boosted conductivity and suppressed restacking. This composite showed outstanding capacitance and cyclic stability.
