Chemical / Process Engineer Needed: Aspen or DWSIM + Techno-Economic Analysis (Biogas / Biomethane)

About ClathraEnergies: ClathraEnergies is a mission-driven deep-tech engineering company developing modular solutions for renewable gas storage and transport, bridging advanced research and practical industrial deployment. We work on renewable gases (biomethane/biogas, biogenic CO₂ and hydrogen), gas treatment, and scalable engineering systems designed to reduce infrastructure barriers and accelerate real-world adoption. About the Project: ClathraEnergies is conducting a techno-economic feasibility study to evaluate flexible storage and transport solutions for biogas/biomethane from decentralized agricultural and territorial sites. The project targets a key barrier to biomethane deployment: limited or congested gas grid injection capacity, whether temporary (peak-shaving) or structural (seasonal/geographical). Many existing biogas plants are also affected by declining cogeneration revenues, while switching to direct biomethane injection often requires costly upgrading and grid connection, with long development timelines. The study assesses options to decouple gas production from grid injection by enabling reversible on-site storage and transport to alternative injection points or centralized hubs. Configurations are compared based on technical feasibility, energy use, and economic performance, with a focus on modular solutions that are easy to integrate on-site and economically accessible for small and medium farm-scale operators. ClathraEnergies is looking for project engineer to perform a process simulation & techno-economic analysis for a project in (Biogas/Biomethane).
