Abstract

Hydrogen produced from renewable energy sources is a valuable energy carrier for linking growing renewable electricity generation with the hard-to-abate sectors, such as cement, steel, glass, chemical, and ceramics industries. In this context, this paper presents a new model of hydrogen production based on solar photovoltaics and wind energy with application to a real-world ceramics factory. For this task, a novel multipurpose profit-maximizing model is implemented using GAMS. The developed model explores hydrogen production with multiple value streams that enable technical and economical informed decisions under specific scenarios. Our results show that it is profitable to sell the hydrogen produced to the gas grid rather than using it for self-consumption for low-gas-price scenarios. On the other hand, when the price of gas is significantly high, it is more profitable to use as much hydrogen as possible for self-consumption to supply the factory and reduce the internal use of natural gas. The role of electricity self-consumption has proven to be key for the project’s profitability as, without this revenue stream, the project would not be profitable in any analysed scenario.

利用可再生氢气使难减排行业去碳化：陶瓷工业的实际应用案例

利用可再生能源生产的氢气是一种宝贵的能源载体，可将不断增长的可再生能源发电与水泥、钢铁、玻璃、化工和陶瓷等难以消减的行业联系起来。在此背景下，本文提出了一种基于太阳能光伏发电和风能的新型制氢模式，并将其应用于现实世界中的陶瓷工厂。为此，本文使用 GAMS 实现了一个新颖的多用途利润最大化模型。所开发的模型探索了氢气生产的多种价值流，可在特定情况下做出技术和经济方面的明智决策。我们的结果表明，在低气价情况下，将生产的氢气出售给天然气电网而不是用于自用是有利可图的。另一方面，当天然气价格明显偏高时，尽可能多地将氢气用于自用以供应工厂并减少天然气的内部使用则更有利可图。事实证明，自用电的作用是项目盈利的关键，因为如果没有这部分收入，项目在任何分析的情况下都无法盈利。
