Abstract This study evaluated the effects of vegetation and internal water storage (IWS) on evapotranspiration (ET), hydrologic performance, and water quality in bioretention mesocosms. Twelve mesocosms were configured as planted/free-drainage (PF), planted/IWS (PI), unplanted/free-drainage (UF), and …

Decarbonizing the energy system requires new applications for green hydrogen produced via electrolysis, especially in high-emission sectors. This study investigates the technoeconomic feasibility of off-grid on-farm hydrogen production integrated with intermittent renewables in Australia and the Netherlands, …

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 …

Small wind turbines face significant challenges in achieving commercial viability due to lower efficiency and higher energy costs compared to utility-scale systems and competing renewable technologies. Counter-rotating dual-rotor wind turbines (CR-DRWTs) with dual-rotational armature configurations offer …

The growing adoption of residential and community-based photovoltaics (PV) have raised concerns about grid congestion and transformer overload. This paper evaluates three strategies for PV–battery integration in decentralised energy communities using real network and residential data to address these …

The global clean energy transition goals require commitment from every country. Different locations however present different technical and economic viability for increasing the penetration of variable renewable energy (VRE) resources to meet national targets. This work presents a comparative economic …

Energy conservation is crucial in wireless ad hoc sensor network design to increase network lifetime. Since communication consumes a major part of the energy used by a sensor node, efficient communication is important. Topology control aims at achieving more efficient communication by dropping links …

OBJECTIVE: To evaluate if using surface neuromuscular electrical stimulation (NMES) for paralyzed lower-limb muscles results in an increase in energy expenditure and if the number of activated muscles and duty cycle affect the potential increase. DESIGN: Cross-sectional study. RESULTS: Energy expenditure …

An energy harvesting device for obtaining energy from drops without needing of moving the drops along the device, in a reduced scale and combinable with other types of harvesting devices, the energy harvesting device comprising one or more triboelectric generators comprising a bottom electrode, a friction …

While modern wind turbines have become by far the largest rotating machines on Earth with further upscaling planned for the future, a renewed interest in small wind turbines (SWTs) is fostering energy transition and smart grid development. Small machines have traditionally not received the same level …
