G4iE participates in EU-level research and innovation initiatives with strong engineering, modelling, and techno-economic expertise. Our contribution spans proposal writing, concept development, process engineering packages, and digital simulation tools.

Techno-economic modelling for hydrogen, ammonia, CCUS, biogas and heat-pump systems. We develop detailed CAPEX/OPEX models, levelised cost assessments (LCOH/LCOA), sensitivity analyses, and scenario simulations to support feasibility studies, investment decisions, and process optimisation.

We deliver high-quality PFDs and P&IDs in AutoCAD Plant 3D and ensure accurate specification and selection of all critical components—valves, instruments, pumps, heat exchangers, and supporting process equipment—according to project requirements and industry standards.

We deliver detailed 3D pipe routing in AutoCAD Plant 3D and complete piping stress calculations in AutoPIPE, ensuring compliance with design codes, proper support layout, thermal expansion management, and overall system integrity.

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

We create tailored desktop and web-based tools in Python and Excel VBA to streamline calculations, visualise data, and support efficient project development.

Leveraging our deep knowledge in Power-to-X technologies, we deliver detailed process engineering, feasibility studies, and techno-economic assessments for large-scale hydrogen production plants.

Our expertise extends to the design and implementation of green ammonia and methanol plants, integrating renewable energy sources and advanced technologies to produce sustainable fuels and chemicals.

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

We offer comprehensive solutions for carbon capture, from feasibility studies to detailed design, helping our clients meet their sustainability goals and regulatory requirements.
