G4iE / DANISH ENGINEERING & INNOVATION
We combine energy-system engineering, process heat integration and physics-based digital twins to help industry assess decarbonisation options and make practical 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 connect technical design, electrical and thermal modelling, and economic analysis. Research teams and industrial partners can compare energy options, understand operating constraints and plan the next engineering step.
G4iE combines core energy-engineering expertise with project-specific specialist resources and technical collaborations, enabling multidisciplinary delivery across modelling, optimisation, AI and software development.
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.
For future collaborative R&D, G4iE can contribute process heat and energy-system integration, digital twins, storage and flexibility assessment, control-strategy evaluation, simulation-based AI validation and techno-economic analysis.
These are potential contributions to new collaborations. Confirmed IN4GRID responsibilities follow the agreed project work plan.

02 / CAPABILITIES
Engineering-led, physics-based work from system concepts and evidence to pilot design and implementation support.
We model renewable generation, battery energy storage systems (BESS), thermal storage and grid interaction as one system. Studies assess storage sizing, energy flows and continuity of supply for industrial and critical loads.
We develop physics-based digital twins of electrical, thermal and industrial systems. Forecasting, optimisation and model predictive control support assessment of energy management and dispatch strategies.
Studies connect process heat demand, temperature requirements, equipment limits and renewable variability. Applications include thermal storage, heat pumps, battery storage, heating, ventilation and air conditioning (HVAC), and industrial loads. Control strategies and AI algorithms are tested and benchmarked in simulation.
We assess hydrogen integration, Power-to-X (PtX) pathways, biogas and renewable fuels, considering their electrical, thermal and process interfaces within the wider energy system.
We compare technical feasibility, capital and operating expenditure (CAPEX/OPEX), energy and heat costs, lifecycle impacts and greenhouse-gas emissions. Assessments support technology selection, business cases and investment planning.
We support concept and basic engineering for process heat, waste-heat recovery, thermal storage and carbon-management systems. Work can include process flow diagrams (PFDs), piping and instrumentation diagrams (P&IDs), equipment integration and technical specifications.
Computational fluid dynamics (CFD) supports assessment of heat transfer, fluid flow, pressure distribution and thermal performance. Integration studies compare heat pumps, renewable heat, electrification and hybrid heating against process requirements. Pilot support is agreed with industrial operators and technology suppliers.
AI models for energy systems need more than a good prediction score. We use physics-based simulation and engineering benchmarks to assess their behaviour under declared operating conditions.
Depending on the project scope, deliverables can include validated simulation environments, benchmark datasets, scenario analysis, technical KPIs and model-performance assessments. Validation scope, assumptions and acceptance criteria are agreed for each project; site performance and operational safety require appropriate project-specific evidence.

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 process demand, temperature requirements, system boundaries, data needs and success criteria.
Compare integration designs, storage sizes and control strategies against operating, cost and emissions scenarios.
Present the engineering evidence, uncertainties and validation needs for the next design or pilot decision.
04 / APPLICATIONS & FOCUS AREAS
G4iE supports industrial decarbonisation by connecting process heat, renewable energy, storage and control with engineering and economic evidence.
Illustrative imageryWe assess how renewable energy, heat recovery, electrification and storage can serve industrial processes. Models compare energy balances, temperature requirements, equipment limits and operating costs to support pilot and demonstration planning.
