The power capacity of renewable energy sources is constantly increasing through the installation of new units, primarily comprising the most mature technologies such as wind and solar energy converters, as well as through the implementation of innovative technologies that are currently at an infant stage of development. The aim of this study was to investigate the prospects of implementing hydrogen technologies in the electricity network as an electricity production unit or/and utilise the produced hydrogen as transportation fuel. Three main scenarios were identified to be the most appropriate for this: (1) Support of the electrical grid via a fuel cell; (2) participation of a hydrogen production and fuel cell system in the electricity and transportation markets; and (3) participation in the transportation market. The results indicated that a fuel cell generator providing ancillary services is not economically viable in the investigated case study, while implementing a hydrogen production unit with a hydrogen fuel selling price between 4 and 114 €/kgH₂, depending on the electrolyser’s power input, will yield positive results. For the third scenario, the hydrogen fuel price ranged between 3.6 and 15.0 €/kgH₂. This research shows that hydrogen technologies can be used in the electricity and transportation markets from a technical point of view. However, from an economic point of view, a hydrogen system used only for a single application does not seem to be financially appealing. This suggests that reducing the investment cost and/or limiting operating costs is mandatory to support this type of investment.

通过安装新的设备（主要包括最成熟的技术，例如风能和太阳能转换器），以及通过实施目前处于发展初期的创新技术，可再生能源的动力容量正在不断增加。这项研究的目的是研究在电力网络中将氢技术用作电力生产单位或/和将产生的氢用作运输燃料的前景。确定了三个最适合此情况的方案：（1）通过燃料电池支持电网；（2）氢生产和燃料电池系统参与电力和运输市场；（三）参与运输市场。根据电解槽的功率输入，图_2中的曲线将产生肯定的结果。对于第三种情况，氢燃料价格在3.6至15.0€/ kgH _2之间。这项研究表明，从技术角度来看，氢技术可用于电力和运输市场。但是，从经济角度来看，仅用于单一用途的氢气系统似乎在经济上并不吸引人。这表明必须降低投资成本和/或限制运营成本才能支持此类投资。
