G4iE / DANISH ENGINEERING & INNOVATION
We connect system engineering, physics-based models and commercial evidence to make clean energy concepts ready for real decisions.
01 / ABOUT G4iE
G4iE — Group for Innovative Engineering — is a Danish engineering and innovation company working across the interfaces of power, heat, storage and hydrogen.
We bring technical design, electrical and thermal modelling, and economic analysis into one conversation. That helps research teams and industrial partners see trade-offs early and choose a credible path forward.
See our approachG4iE is a beneficiary of IN4GRID, a €4 million Horizon Europe Research and Innovation Action advancing AI-enabled flexibility, grid integration, and coordinated distributed energy resources and storage.
G4iE’s energy-system modelling, flexibility assessment, digital twins, and techno-economic evaluation connect AI research with engineering.

02 / CAPABILITIES
Engineering-led, physics-based work from system concepts and evidence to pilot design and implementation support.
Hybrid system integration brings together renewables, BESS (battery energy storage systems) and thermal energy storage, with grid interaction and flexibility for critical loads.
Physics-based modelling and digital twins guide AI-assisted forecasting, flexibility modelling and optimisation of energy management and grid/consumer coordination.
Hydrogen integration and Power-to-X pathways for e-fuels, biogas and other renewable fuels, with sector coupling in view.
CAPEX/OPEX and LCOE/LCOH modelling, lifecycle assessment (LCA) and carbon intensity inform business cases, scenario comparison and decision support.
Concept and basic engineering, PFD/P&ID, equipment integration and technical specifications for heat pumps, waste heat recovery, district heating, solar thermal, geothermal systems and CCUS. Pilot and demonstration design, scale-up, safety and risk considerations, and implementation support. Advanced engineering simulations, including Computational Fluid Dynamics (CFD), for heat transfer, fluid flow, pressure distribution and thermal performance optimisation.
Illustrative imageryPOWER / HEAT / STORAGE / HYDROGEN
Generation, conversion, storage and demand influence one another. We study those interfaces together, so a promising component becomes a workable system.
03 / HOW WE WORK
Every assignment begins with the operating reality: constraints, data quality, interfaces and the decision the work must support.
Work with usDefine system boundaries, operating needs, assumptions and success criteria.
Connect engineering models with cost and operating scenarios to reveal trade-offs.
Present the evidence, uncertainties and design choices in a form teams can use.
04 / APPLICATIONS & FOCUS AREAS
G4iE supports research and industrial teams with system integration, decarbonisation and demonstration planning.
Illustrative imageryWe help define engineering interfaces, model operating scenarios and compare designs for pilots and demonstrations. Technical, techno-economic and lifecycle evidence grounds the next implementation step.
