We support EU Horizon Cluster 5 and Denmark national calls with system engineering, techno-economic analysis, and exploitation-oriented deliverables, ensuring projects move beyond reports toward deployable and replicable solutions.

Techno-economic modeling for hydrogen, ammonia, CCUS, biogas, heat-pump systems, and energy storage. We deliver transparent CAPEX/OPEX breakdowns, LCOH/LCOA calculations, and sensitivity analyses to support robust investment and design decisions.

Process and project engineering for energy and industrial plants, with a strong focus on system integration, interfaces, and FOAK risk reduction. Our work spans concept design, layout definition, integration studies, preparing PFDs, P&IDs and heat & mass balances, and support to procurement, construction, and commissioning.

Support for developers, investors and advisors evaluating hydrogen, electricity supply, PtX and e-fuels proposals. G4iE provides technical compliance review, mass and energy balance checks, operating-profile assessment, RFNBO/GHG assumption review, bid scoring models, pricing benchmark support, and technical risk flagging for investment and negotiation decisions.

We use ANSYS Fluent and CFX to simulate fluid flow, heat transfer (thermal modelling), and complex physical interactions, helping improve system performance and support data-driven design decisions.

We develop practical, physics-based digital twins for industrial energy systems — enabling performance prediction, control strategy testing, and what-if optimization before changes are made on site. Using a Python backend with interactive user interfaces, we deliver decision-ready models that support FEED, commissioning, and operations.

Technical assessment of hydrogen and electricity supply concepts for e-fuels projects, including process integration, supply profile matching, conversion pathway assumptions, energy demand, RFNBO/GHG-relevant inputs, and technical deliverability.

We provide end-to-end engineering services for biogas plants, including process design, component selection, and system optimization, ensuring maximum efficiency and reliability.

Engineering and analysis of battery energy storage systems (BESS) for grid and industrial applications, including second-life batteries, thermal management, degradation-aware lifetime modeling, and system-level integration. Design and integration of large-scale industrial heat pump systems for district heating and industrial decarbonisation. Focus on waste-heat utilisation, system optimisation, and techno-economic assessment.

We provide comprehensive solutions for carbon capture and storage, from feasibility studies to detailed design, helping clients meet sustainability targets and regulatory requirements.
