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场景下的原始模型结果，属于一篇探讨社区能源与水系统集成的Power-to-H3概念的学术论文的配套研究内容。
本数据集公开后可作为该学术论文及Els van der Roest博士论文的补充数据，亦可供其他研究人员使用。
本数据集生成于2019年1月至2019年4月的模型运行阶段。
该论文的摘要如下：在从化石能源向可再生能源转型的进程中，能源系统需在保持可靠稳定且经济可负担的同时实现清洁化。鉴于可再生能源发电与能源需求均具有间歇性特征，需采用包含能源转换与存储的集成系统方案。我们提出一种社区能源系统概念：将本地生产的可再生能源部分转换并以热能与氢能形式存储，同时配套雨水收集、存储、净化与利用流程，即Power-to-H3。本研究开发了相应模型以构建能源平衡并开展技术经济分析，其中包含该概念下的避免成本分析。研究结果表明，一座容量为8.7兆瓦峰瓦（MWp）的太阳能电站搭配屋顶太阳能光伏板与雨水收集系统，可在全年为900户住宅提供热能（20太焦，TJ），同时满足其近半数的用水需求（36000立方米），并为540辆氢能电动汽车供应氢能（90吨）。氢能（8.7欧元/千克）与热能（26欧元/吉焦，GJ）的生产成本均低于荷兰当前的终端用户售价（10欧元/千克与34欧元/吉焦，GJ），证明该系统具备经济可行性。若将避免的成本纳入考量，上述成本可降低20%至26%，同时每年可减少3600吨二氧化碳排放。上述结果证实，完全依托太阳能与雨水，以可靠、经济且清洁的方式为社区提供上述全部公用事业服务是可行的。
