| bcvw4_v1 | Rethinking electrolyzer design for optimal waste-heat utilization | Green hydrogen and electric heating have received attention as separate solutions to make more sustainable material and energy supply networks. However, their combination has rarely been studied to supply both hydrogen and heat to the industry. The conventional design of electrolyzers overlooks the potential for waste-heat utilization. Moreover, the possibility of upgrading the waste heat using heat pumps has not been sufficiently explored. This work analyzes the benefit of designing electrolyzers for waste-heat utilization, evaluates the combination of low temperature electrolysis and heat pumps under different operating conditions, and compares its performance with other electric heating options. The results show that designing for waste-heat utilization leads to more compact electrolyzers and can reduce cost and emissions. Moreover, if there is a medium-temperature heat demand, waste heat upgrading via heat pumps is preferable to direct use for lower-temperature demand. | 2024-11-15T16:55:54.623802 | 2024-11-15T17:11:03.157173 | 2024-11-15T17:10:36.154751 | ecsarxiv | 1 | accepted | 1 | 1 | https://doi.org/10.1149/osf.io/bcvw4 | CC-By Attribution 4.0 International | electric heating; heat pumps; hydrogen; low-temperature electrolysis; optimization; process systems engineering; synergy; techno-economic analysis; waste-heat upgrading; waste-heat utilization; water electrolysis | ["electric heating", "heat pumps", "hydrogen", "low-temperature electrolysis", "optimization", "process systems engineering", "synergy", "techno-economic analysis", "waste-heat upgrading", "waste-heat utilization", "water electrolysis"] | Aldwin Lois Galvan Cara; Dominik Bongartz | [{"id": "9r2qm", "name": "Aldwin Lois Galvan Cara", "index": 0, "orcid": null, "bibliographic": true}, {"id": "8w6r4", "name": "Dominik Bongartz", "index": 1, "orcid": "0000-0003-1790-0235", "bibliographic": true}] | Aldwin Lois Galvan Cara | Engineering; Electrochemical Engineering; Energy; Chemical Engineering; Simulation; Mathematical Modeling; Electrolyzers; Other Chemical Engineering | [{"id": "5ae728ad4667e6000f98dd92", "text": "Engineering"}, {"id": "5ae728ad4667e6000f98dd98", "text": "Electrochemical Engineering"}, {"id": "5ae728b24667e6000f98dde3", "text": "Energy"}, {"id": "5ae728b34667e6000f98de09", "text": "Chemical Engineering"}, {"id": "5ae728b34667e6000f98de0c", "text": "Simulation"}, {"id": "5ae728b44667e6000f98de2b", "text": "Mathematical Modeling"}, {"id": "5ae728b64667e6000f98de6f", "text": "Electrolyzers"}, {"id": "5ae728b74667e6000f98de93", "text": "Other Chemical Engineering"}] | https://osf.io/download/67377d33bbc22d9ef79430fc | 0 | not_applicable | not_applicable | [] | 2025-04-09T21:06:12.090905 |
