“…In contrast, while the LCOE and LCOH implications reduced to 0.0325-0.0755 $/kWh and 1.375-1.59 $/kg in Lutak City, Iran, due to the high wind speed conditions in this region (Rezaei et al 2021), the LCOH was 3.1 and 4.02 $/kg in Turkey and Pakistan, respectively (Genç et al 2012;Iqbal et al 2019). Moreover, while the LCOH in South Africa was between 6.34 and 8.97 $/kg (Ayodele et al 2021), it was 7.3 $/kg in Germany (Herwartz et al 2021).…”

Hydrogen energy, as clean and efficient energy, is considered significant support for the construction of a sustainable society in the face of global climate change and the looming energy revolution. Hydrogen is one of the most important chemical substances on earth and can be obtained through various techniques using renewable and nonrenewable energy sources. However, the necessity for a gradual transition to renewable energy sources significantly hampers efforts to identify and implement green hydrogen production paths. Therefore, this paper’s objective is to provide a technological review of the systems of hydrogen production from solar and wind energy utilizing several types of water electrolyzers. The current paper starts with a short brief about the different production techniques. A detailed comparison between water electrolyzer types and a complete illustration of hydrogen production techniques using solar and wind are presented with examples, after which an economic assessment of green hydrogen production by comparing the costs of the discussed renewable sources with other production methods. Finally, the challenges that face the mentioned production methods are illuminated in the current review.

“…The impact of charging infrastructure positioning and specification on the relevant LCC has not been discussed in detail. While hydrogen costs for FCEMU refueling with hydrogen from onsite electrolysis based on electricity produced from local wind power plants (WPP) have been analyzed in Herwartz (2020) [5], the feasibility and cost assessment of BEMU recharging with electricity produced from local RES has not yet been investigated.…”

“…The technical feasibility and assessment of lifecycle costs (LCC) of regional train transport with zero-tailpipe drivetrain multiple units is subject to several feasibility studies, especially in German research [4][5][6][7]. The results show a strong dependency on the rail line and network characteristics, such as grid topology, length of line, electrified sections and schedule.…”

Battery electric multiple units (BEMU) are an effective path towards a decarbonized regional rail transport on partly electrified rail lines. As a means of sector coupling, the BEMU recharging energy demand provided through overhead line islands can be covered from decentralized renewable energy sources (RES). Thus, fully carbon-free electricity for rail transport purposes can be obtained. In this study, we analyze cost reduction potentials of efficient recharging infrastructure positioning and the feasibility of covering BEMU energy demand by direct-use of locally produced renewable electricity. Therefore, we set up a model-based approach which assesses relevant lifecycle costs (LCC) of different trackside electrification alternatives comparing energy supply from local RES and grid consumption. The model-based approach is applied to the example of a German regional rail line. In the case of an overhead line island, the direct-use of electricity from adjacent wind power plants with on-site battery storage results in relevant LCC of EUR 173.4 M/30a, while grid consumption results in EUR 176.2 M/30a whereas full electrification results in EUR 224.5 M/30a. Depending on site-specific factors such as existing electrification and line lengths, BEMU operation and partial overhead line extension can lead to significant cost reductions of recharging infrastructure as compared to full electrification.

“…Climate awareness and environmental protection have gained momentum in the recent past and they have triggered the development of new and more efficient processes and materials [1][2][3]. Among others, this has led to the reevaluation of many traditional industrial-scale processes, in the pursuit of new renewable energy sources [4,5], lower consuming methods, and more efficient and stable catalysts. When it comes to the development of new materials, the use of non-metals [6][7][8] or non-noble metals [9][10][11] catalysts are two major trends currently involving a big volume of research for many different processes.…”
