We support EU Horizon Cluster 5 and Denmark national calls with system engineering, techno-economic analysis, and exploitation activities. Right now, G4iE is a Horizon Europe beneficiary in a €4.0m RIA consortium.

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, from concept through FEED and detailed design. Our work spans process design, layout definition, integration studies, procurement, construction and commissioning support.

We evaluate hydrogen, electricity, and PtX proposals for developers, investors and off-takers: technical compliance, pricing, risks, and supply chain credibility assessments. Deliverables include scorecards, ranking benchmarks, and recommendation reports.

We use ANSYS Fluent and CFX to simulate fluid flow, heat transfer, and thermal modelling, and optimise 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 scenario analysos. Using a Python-backend UI and interactive dashboards, we 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.

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