Abstract

The aim of this study is to quantify and utilize waste heat from wind-farm-powered water electrolysers and ammonia cracking. The port of Rotterdam, as a case study, has been analyzed where the transport of 4.6 Mt hydrogen and water electrolysis, powered by wind farms, is planned. A dynamic model was developed to calculate waste heat from an electrolyser powered by fluctuating electricity inputs from offshore wind power. Moreover, thermal analysis of ammonia cracking process streams was conducted. It was observed that integrating water electrolysis waste heat into the ammonia cracking process is not only a promising novel application for the reuse of the electrolysis waste heat, but also it can potentially enhance cracking efficiency by 2 % while creating synergies within the hydrogen industry. Additionally, waste heat can be used for district heating saving more than 70 % of energy and reducing CO₂ by just as much. In parallel, cold utilisation from ammonia cracking was explored for CO₂ and H₂ compression, as well as industrial cold storage to observe that technical implementation is possible.

制氢和进口热能回收利用：水电解余热和氨裂解冷利用研究

这项研究的目的是量化和利用来自风力发电厂的电解水和氨裂解的废热。作为一个案例研究，对鹿特丹港进行了分析，该港口计划运输460万吨氢气和电解水，由风力发电场供电。建立了一个动态模型来计算由海上风电输入的波动电力驱动的电解槽产生的废热。并对氨裂解工艺流程进行了热分析。结果表明，将水电解废热整合到氨裂解过程中，不仅是电解废热再利用的一个有前景的新应用，而且可以在氢气工业中产生协同效应的同时，将裂解效率提高2%。此外，余热可用于区域供热，节省70%以上的能源，并减少同样多的二氧化碳。与此同时，研究人员还探索了氨裂解对二氧化碳和氢气压缩的冷利用，以及工业冷库，以观察技术实施的可能性。
