The integration of biomethane into existing gas distribution networks is a key component of the energy transition, but its implementation is often limited by local network constraints. This study investigates the impact of local pressure losses on biomethane injection capacity in a real-world low-pressure …

Ammonia is a major nitrogenous constituent of municipal wastewater and poses environmental challenges when discharged to receiving waters. Conventional biological treatment processes can be limited by operational instability, sensitivity to loading conditions, and greenhouse gas emissions, motivating …

With more emerging technologies for hydrogen storage, it has become more important than ever to properly evaluate different options to ensure technical feasibility and legal compliance. In this study the technical aspects and legal requirements of two main storage technologies: underground gas cylinders …

From March 2014 to September 2016, the instruments in the Rosetta Plasma Consortium (RPC) onboard the European Space Agency's Rosetta spacecraft measured the plasma environment of comet 67P/Churyumov-Gerasimenko (67P/CG) in detail. Multiple datasets of these instruments show instances of asymmetric and …

Context and purpose Following the rapid growth of the voluntary carbon removal market, and the need to scale high-integrity, internationally recognised standards, the EU has developed a Carbon Removal and Carbon Farming Regulation (CRCF) (2024/3012) for DACCS (direct air carbon capture and storage), …

Biomethane is emerging as a key renewable gas in both mature and developing energy systems worldwide. Driven by climate-neutrality objectives, energy-security concerns, and rising waste-to-energy ambitions, global biomethane production is expected to expand rapidly in the coming decade. In Europe, this …

Traditional scientific research has produced valuable knowledge, yet its linear, top-down logic often fails to address the complexity of local communities. This results in a gap between knowledge and action, where interventions lack legitimacy and impact. Participatory Action Research (PAR) has emerged …

To broaden the application of biomethanation for energy storage and renewable integration, this study investigates the performance of a trickle-bed reactor (TBR) for hydrogen (H2) utilisation in biogas upgrading, using both pure Carbon dioxide (CO2) and biogas-derived CO2 as substrates for methane (CH4) …

Although attitudes toward sustainable commuting have become more positive in many countries, actual behavioral change remains slow. Meanwhile, the transport sector remains a major source of greenhouse gas emissions in Europe, with significant differences in sustainability efforts between governments …

Methane, the primary component of natural gas, emits less carbon dioxide than other petroleum-based fuels but faces challenges in efficient storage and transportation. Advanced adsorption materials provide a safe and cost-effective solution, with metal–organic frameworks (MOFs) emerging as promising …
