Abstract

Integrating renewable energies with hydrogen production via electrolysis and utilizing hydrogen as a fuel for solid oxide fuel cells (SOFCs) presents a synergistic approach towards sustainable energy generation. This coupling offers enhanced flexibility, allowing for efficient energy storage and distribution, thereby addressing intermittency issues associated with renewable sources. Additionally, the utilization of hydrogen in SOFCs enables high-efficiency power generation with reduced emissions, contributing to the transition towards a cleaner energy landscape. In the present study, four types of renewable energies, namely solar, biomass, geothermal, and wind, produce hydrogen by coupling power generation units and a proton exchange membrane electrolyzer (PEME). Then, the produced hydrogen is stored and used for later utilization in an SOFC subsystem. A 4E (energy, exergy, exergy-economic, and environmental) study is conducted for the proposed systems through a sensitivity study and design optimization. In the best output performance mode, the best exergy efficiency is obtained by the biomass-based system, which is equal to 9.40 %, and the lowest values for total cost rate and unit cost of outputs are achievable by the geothermal-based system, with values of 27.72 $/h and 43.23 $/GJ.

用于绿色氢燃料 SOFC 的太阳能、生物质、地热和风力发电系统的 4E 分析和优化比较

通过电解将可再生能源与氢气生产结合起来，并利用氢气作为固体氧化物燃料电池（SOFC）的燃料，是实现可持续能源生产的一种协同方法。这种耦合提供了更大的灵活性，允许高效的能源存储和分配，从而解决与可再生能源相关的间歇性问题。此外，在 SOFC 中利用氢气可实现高效发电并减少排放，有助于向更清洁的能源环境过渡。在本研究中，太阳能、生物质能、地热能和风能这四种可再生能源通过发电装置和质子交换膜电解槽（PEME）的耦合产生氢气。然后，在 SOFC 子系统中储存和利用所产生的氢。通过敏感性研究和优化设计，对拟议系统进行了 4E（能源、放能、放能经济和环境）研究。在最佳输出性能模式下，生物质系统的放能效率最高，为 9.40%；地热系统的总成本费用和单位输出成本费用最低，分别为 27.72 美元/小时和 43.23 美元/GJ。

期刊介绍： Energy is a multidisciplinary, international journal that publishes research and analysis in the field of energy engineering. Our aim is to become a leading peer-reviewed platform and a trusted source of information for energy-related topics. The journal covers a range of areas including mechanical engineering, thermal sciences, and energy analysis. We are particularly interested in research on energy modelling, prediction, integrated energy systems, planning, and management. Additionally, we welcome papers on energy conservation, efficiency, biomass and bioenergy, renewable energy, electricity supply and demand, energy storage, buildings, and economic and policy issues. These topics should align with our broader multidisciplinary focus.
