Dataset accompanying the publication: Introducing Power-to-H3: combining renewable electricity with heat, water and hydrogen production and storage in a neighbourhood

This dataset contains raw model results from 2 different scenario's as part of a publication on the the Power-to-H3 concept for system integration in a neigbhourhood energy- and water system. It is being made public to act as supplementary data for publication(s) and the PhD thesis of Els van der Roest. Also, it might be used by other researhers. <br> The dataset was created during model runs in the period between January 2019 - April 2019. <br> Abstract of the paper: In the transition from fossil to renewable energy, the energy system should become clean, while remaining reliable and affordable. Because of the intermittent nature of both renewable energy production and energy demand, an integrated system approach is required that includes energy conversion and storage. We propose a concept for a neighbourhood where locally produced renewable energy is partly converted and stored in the form of heat and hydrogen, accompanied by rainwater collection, storage, purification and use (Power-to-H3). A model is developed to create an energy balance and perform a techno-economic analysis, including an analysis of the avoided costs within the concept. The results show that a solar park of 8.7 MWp combined with rainwater collection and solar panels on roofs, can supply 900 houses over the year with heat (20 TJ) via an underground heat storage system as well as with almost half of their water demand (36,000 m3) and 540 hydrogen electric vehicles can be supplied with hydrogen (90 tonnes). The production costs for both hydrogen (8.7 €/kg) and heat (26 €/GJ) are below the current end user selling price in the Netherlands (10 €/kg and 34 €/GJ), making the system affordable. When taking avoided costs into account, the prices could decrease with 20–26%, while at the same time avoiding 3600 tonnes of CO2 a year. These results make clear that it is possible to provide a neighbourhood with all these different utilities, completely based on solar power and rainwater in a reliable, affordable and clean way.

本数据集包含两项不同情景下的原始模型运行结果，相关内容属于一篇关于社区能源与水系统集成的Power-to-H3（Power-to-H3）概念的学术论文成果。本数据集公开后可作为Els van der Roest博士学位论文及相关学术出版物的补充数据，亦可供其他研究人员参考使用。

论文摘要如下：在从化石能源向可再生能源转型的过程中，能源系统需在保持可靠、经济的同时实现清洁化。由于可再生能源发电与能源需求均具有间歇性特征，因此需要采用包含能源转换与存储的集成系统方案。本研究提出一种社区能源方案：将本地生产的可再生能源部分转换并以热能、氢能形式存储，同时配套雨水收集、存储、净化与利用流程，即Power-to-H3概念。本研究开发了一套模型，用于构建能源平衡并开展技术经济分析，其中包含该方案下的成本节约分析。研究结果表明，一座8.7兆瓦峰（MWp）的光伏电站，结合屋面光伏与雨水收集系统，可在一年内为900户家庭提供总计20太焦（TJ）的热能（通过地下储热系统实现）、满足其近一半的用水需求（36000立方米），同时可为540辆氢能电动汽车提供总计90吨的氢能补给。氢能（8.7欧元/千克）与热能（26欧元/吉焦）的生产成本均低于荷兰当前的终端用户售价（分别为10欧元/千克与34欧元/吉焦），证明该系统具备经济可行性。若计入成本节约收益，相关产品售价可降低20%~26%，同时每年可减少3600吨二氧化碳排放。上述结果表明，完全基于太阳能与雨水，即可为社区提供上述全部公用事业服务，且兼具可靠性、经济性与清洁性。
