Life cycle assessment of green hydrogen production through electrolysis: A literature review

Sustainable Energy Technologies and Assessments, Год журнала: 2024, Номер 69, С. 103923 - 103923

Опубликована: Июль 31, 2024

This study reviews the electrolysis techniques for green-hydrogen (GH2) production, with primary focus on their environmental sustainability implications. Different stages of GH2 value chain are characterized regarding life cycle analysis (LCA), presenting methods, materials, energy sources, and efficiency. Qualified LCA results would lead to proper decision-making, which depends input choices data quality used. Therefore, inventory useful technical production in studies reviewed. Also, recent developments toward potentially enhancing discussed. The showed that solar wind energies as most promising sources lower Global Warming Potential (GWP) turbine cases. reported impacts (EIs) proton-exchange membrane (PEM) technology. There is still limited comparing various EIs (e.g. freshwater eutrophication) accompanying costs. However, it recommended consider H2 mainly efficiency, consumption lifetime along miniaturization. future may final use produced fuel cells), heat recovery materials recycling complete visibility towards optimizing efficiency EIs.

The efficient and sustainable supply transport of water is a key component to any functioning civilisation making the role urban systems (UWS) inherently crucial wellbeing its customers. However, managing not simple task. Whether it aging infrastructure, transient flows, air cavities or low pressures; can be lost as result many issues that face UWSs. complexity those networks grows with high urbanisation trends climate change companies regulatory bodies in need new solutions. So, comes no surprise researchers are invested innovating within industry ensure future our safe. Deep reinforcement learning (DRL) has potential tackle complexities used very challenging relies on deep neural for function approximation representation. This technology conquered fields due impressive results effectively revolutionise UWS. In this article, we explain background DRL milestones field using novel taxonomy algorithms. will followed by review applications UWS which focus distribution stormwater systems. concluded critical insights how benefit different aspects

Experimental assessment of the energy performance of a renewable air-cooling unit based on a dew-point indirect evaporative cooler and a desiccant wheel

Energy Conversion and Management, Год журнала: 2024, Номер 310, С. 118486 - 118486

Опубликована: Май 6, 2024

Given the escalating energy consumption in cities worldwide, it is crucial to investigate utilization of sustainable technologies and renewable sources. The number empirical studies on performance hybrid air-cooling systems limited. Therefore, objective this work experimentally study a novel unit. This prototype mainly composed desiccant wheel dew-point indirect evaporative cooler independently control temperature, humidity, carbon dioxide levels indoor air. 64 experimental tests are carried out fit an model unit, focusing outlet air conditions coefficient performance. In addition, several indices developed for cooler: (i) moisture removal capacity; (ii) capacity per unit electrical power-consumption; (iii) efficiency (iv) cooling power-consumption. highest values dehumidification capacity, sensible achieved most severe outdoor conditions, namely 19.02 kg·h−1, 21.49 kW 11.0, respectively. can serve as reference research feasibility scenarios heat events climate change world.
