As the European Union intensifies its response to climate emergency, increased focus has been placed on hard-to-abate energy-intensive industries. Primary among these is steel industry, a cornerstone of economy and industry. With emergence new hydrogen-based steelmaking options, particularly through hydrogen direct reduction, structure global production supply chains will transition from being based low-cost coal resources that electricity therefore production. This study examines techno-economic options for three countries Germany, Spain, Finland under five different chain configurations compared local Results suggest high costs transportation make cost competitive produced with imported hydrogen, ranging 465 545 €/t crude (CS) 380–494 €/tCS 2030 2040, respectively. Conversely, imports hot briquetted iron Morocco become economically chains. Given capital energy intensive nature critical investment decisions are required in this decade, research serves provide deeper understanding Europe.

Installing multi-renewable energy (RE) power plants at designated locations, known as RE parks, is a promising solution to address their intermittent power. This research focuses on optimizing parks for three scenarios: photovoltaic (PV)-only, wind-only, and hybrid PV-wind, with the aim of generating green hydrogen in locations different potentials. To ensure rapid response fluctuations, Proton Exchange Membrane (PEM) electrolyzer employed. Furthermore, this proposes detailed models manufacturer-provided wind curves, efficiency against its operating power, cost towards capacity. Two optimization cases are conducted MATLAB, evaluating optimum sizes minimizing levelized (LCOH) using classical discrete combinatorial method determining ideal PV-to-wind capacity ratio PEM within PV-wind particle swarm optimization. Numerical simulations show that power-based production more cost-effective than PV-only parks. The lowest LCOH, $4.26/kg H2, highest $14.378/kg obtained from wind-only configurations, respectively. Both occurred Adum-Kirkeby, Denmark, it has average speed irradiance level. Notably, LCOH reduced configuration. results suggest 65:35 indicate sensitive electrolyzer's electricity tariff variation. study highlights two important factors, i.e., selecting suitable location based available resources size between park.

With its ability to store and transport energy without releasing greenhouse gases, hydrogen is considered an important driver for the decarbonisation of systems. As future import prices from global markets are subject large uncertainties, it unclear what impact different derivative will have on German system. To answer that research question, this paper explores three price scenarios derivatives system in a climate-neutral setting Europe 2045 using models. The analysis shows quantities electricity generated as well installed capacities generation electrolysis increase rises. However, resulting differences between vary across results further indicate domestic (and European) production often cost-efficient.
