[ software demonstration ]
The primary business model of the project is to sell green ammonia to international markets , such as Europe and Japan . Additionally , any surplus hydrogen is planned to be sold to the local gas distribution company for blending into the gas network . Regarding renewable fuel prices , the market price for green hydrogen is set at € 2 / kg .¹ For ammonia , the sale price is € 1,300 / ton .²
Pre-feasibility study scope and structure
This pre-feasibility study addresses key questions for the business development team and management of the hypothetical energy development company behind the project . It follows a typical feasibility workflow used in solar and wind project development during greenfield stages and aims to demonstrate how this process can be internalized and streamlined using Southern Lights software .
The study evaluates various aspects of the project to determine its feasibility and potential benefits under different scenarios , including :
• Project scope and boundary conditions : defining project limits and potential extensions
• Key infrastructure and technical design : outlining the necessary infrastructure and technical specifications
• Cost estimation : assessing the project ’ s financial requirements
• Results , optimization and business analysis : analyzing potential outcomes and conducting a business analysis
• Conclusions : summarizing findings summary and providing final recommendations
By systematically addressing this outline , the study aims to provide a comprehensive assessment of the proposed green ammonia production plant ’ s viability and its contribution to sustainable energy solutions .
For the scope of this study , the cost of transportation will be considered an exogenous variable , with the service expected to be procured from an external partner or third party . It is assumed that the project will be able to connect to the required infrastructure for supplying compressed hydrogen and ammonia , with costs determined based on the levelized cost of the infrastructure .
Key infrastructure and design parameters
Based on the project ’ s commercial definitions , several scenarios were considered , each with varying design parameters such as installed electrolyzer capacity , electrolyzer technology , energy source , power plant capacity , and ammonia production capacity . After evaluating the technoeconomic results of the different scenarios , only the case with the most promising results was selected for presentation in this article . Figure 2 presents a diagram of the whole system .
