@bartholomew31

✦ Good day, Techno-economic analysis of gas storage and transport systems requires more than calculations—it needs a structured engineering model that clearly links thermodynamics, process design, and economic performance. My approach is to build transparent calculation frameworks (primarily in advanced Excel with scenario and sensitivity analysis) supported by Aspen/DWSIM simulations to validate mass and energy balances. From there, I structure the CAPEX/OPEX models, derive normalized indicators such as €/Nm³ biomethane or €/MWh energy, and compare technical configurations with clear assumptions and documented reasoning. This makes the analysis reproducible and easy for stakeholders to review or expand later. The final deliverable will include clean calculation sheets, scenario comparisons, and concise explanations showing how design choices influence economic outcomes. Would you like the techno-economic model designed so additional configurations or future datasets can be integrated easily?

@yahyanafea

Hello, I am a chemical and process engineer with experience in gas systems modelling, process simulation and techno-economic analysis. My work typically combines rigorous mass and energy balance calculations with process simulation using Aspen tools and structured Excel models for scenario and sensitivity analysis. For projects like biomethane storage and transport systems, I usually structure the work in three stages: 1. Technical modelling Develop a process representation using Aspen or engineering calculation sheets to define system performance and operating conditions. 2. Techno-economic assessment Estimate CAPEX and OPEX, evaluate energy requirements, and calculate normalized cost indicators such as €/Nm³ of biomethane or €/MWh. 3. Configuration comparison Analyse alternative technical options and clearly document assumptions so the economic impact of design decisions can be understood. I also have experience using Aspen Process Economic Analyzer to support conceptual cost estimation. I would be glad to review your system description and discuss the most appropriate modelling approach. Best regards
