HORIZON-CL4-2027-02-MAT-PROD-32-two-stage: Efficient energy input from renewable sources and energy management in the process industries (Processes4Planet and Innovative Advanced Materials for the EU partnerships)
Funded projects should provide tested pilot-scale systems for industrial heat supply by renewable means and achieve at least a 20% reduction in greenhouse gas emissions. The Commission seeks technologies that use real sites rather than laboratory-scale ones. On top of that, it anticipates tangible means of coping with energy flows amid fluctuations in the renewable electricity grid.

Scientific range: what does the Commission expect from the HORIZON-CL4-2027-02-MAT-PROD-32-two-stage grant?
What outcomes are expected?
Funded projects should deliver validated pilot-scale systems for industrial heat supply from renewable sources, with measurable greenhouse gas reductions of at least 20%. The Commission wants technologies that work on real sites, not just lab-scale setups. On top of that, it expects concrete tools to manage energy flows in the face of the variability of the renewable electricity grid.
What is within scope?
- Industrial heating Electrification: resistive and induction heating, electric boilers, high temperature processes powered by electricity, high voltage electricity.
- Hybrid power systems that gradually reduce reliance on fossil fuels in areas where complete electrification is not feasible.
- Preheating systems based on solar thermal, geothermal and heat pump.
- Phase change materials, chemical heat carriers, high-temperature thermal storage beyond e-fuels: energy storage technologies.
- Scale-based heat capture, storage, and insulation using innovative advanced materials and reducing the use of critical raw materials.
- A combination of energy management systems between production and renewable supply.
- Lab demonstrations on actual industry locations.
Nor in scope: demand-side management purely, through adjusting production schedules to the availability of electricity. Scheduling workarounds is not what the Commission desires but technology-level solutions. That is clearly delineated.
What are the specifically proposed research directions?
- Enhancing productivity and introducing renewable energy in manufacturing operations, with quantifiable CO2 savings throughout the entire system.
- Combined energy systems with new storage components that would level out fluctuations in renewable supplies.
- Solutions: Low to medium temperature (100 to 500 °C): hybrid solutions, heat upgrading, gradual fossil phase-out.
- High-temperature (greater than 500 °C): electrified operations and high-temperature thermal storage.
- Heat storage and insulation materials, which were originally developed to be scaled and recycled.
Scientific strategy: how can you enhance your chances of being funded through HORIZON-CL4-2027-02-MAT-PROD-32-two-stage?
What scientific choices matter most?
- Prove a 20% GHG cut using a plausible baseline. The employment plan is clear. Any suggestion that cannot be measured persuasively will not pass the review.
- Design intermittently, at the outset. The evaluators will indicate proposals that consider renewable fluctuation as a minor issue. It is the engineering issue at the center of this call.
- Do not pursue full electrification when it is not feasible for your industry. The hybrid solutions are more than welcome. They are likely the more plausible way in a number of process industries.
- Relate materials invention to implementation early. If your proposal includes new storage or insulation materials, demonstrate how they can be designed and used. Scalability and industrial requirements should not be an afterthought; they should be incorporated into the design phase.
- Incorporate an actual industrial facility. The computation is open-loop, and actual work on-site is desirable. The difference is familiar to the reviewers.
- Be ready to compile the exploitation plan early, prior to the second-stage submission. The additional pages are there for a purpose.
Consortium & proposal-writing plan: what works best with this type of call?
- Two-stage submission refers to two bites. At the first stage, the evaluation is blind. Take out all the names of the organizations, the acronym, logo, and the names of the staff in the abstract and part B. This is an ensnarement of more consortia than you’d have thought.
- Target between ten and fourteen partners. Process industries include chemicals, steel, cement, and glass – you most likely require sector breadth and geographic spread.
- Industrial partners with actual locations are virtually a choice requirement. Acquire at least two who can conduct pilot demonstrations.
- Academia is a field that deals with materials science and modeling energy systems. You have to have the two sides.
- Incorporate a new SME with expertise in thermal management or energy storage. When the role of an SME is decorative rather than substantive, evaluators will be aware of this.
- This call refers to both co-programmed partnerships (Processes4Planet and IAM to the EU). If the consortium partners are already operational in these partnerships, that should be mentioned.
- If you have never engaged in these partnerships, the first thing you should do is probably find out who has.
How would microfluidics contribute to this topic?
Traditional lab systems are slow when screening new phase change materials or chemical heat carriers under operating conditions. Each experiment produces a single data point, and project cycles do not align with the timelines. Microfluidic systems alter it. It is possible to execute hundreds of formulations under thermal gradients that a chip can control in the time it takes a traditional device to run one trial.
- You would like to understand whether a new phase-change material will remain stable through hundreds of thermal cycles before you are willing to invest in kilogram-scale production. A microfluidic cycling system provides you with that in a few days. Such a speed of iteration is even within the project’s schedule.
- You can use microfluidic high-throughput screening by your materials group to down-select among large collections of insulation candidates prior to any pilot-scale work. Quick and less expensive than the traditional characterization.
- Flow-based platforms. The thermal interface properties and heat transfer coefficients at the small scale are well characterized by flow-based platforms and directly guide the selection of materials for scale-up.
- The microreactor modules can be used to determine chemical heat carrier reaction kinetics, decomposition limits, and reversibility under realistic operating conditions, thereby eliminating unexpected behavior during the pilot stage.
In the case of a consortium dealing with HORIZON-CL4-2027-02-MAT-PROD-32-two-stage, the Microfluidics Innovation Center can facilitate the materials characterization and pre-pilot validation steps, which the Commission is requesting directly in the scope. The ability to evaluate in that manner in the team makes your proposal more credible on the materials-to-deployment pipeline, which is a well-defined evaluator focus in this call.

FAQ – HORIZON-CL4-2027-02-MAT-PROD-32-two-stage
So what is it that this call is all about?
This call is for European process industries (chemicals, steel, cement, glass) that must switch to renewable energy for their heat supply. Those with expertise in materials science, energy systems engineering, thermal storage and process engineering will be a good match. Industry players with production facilities are essential, as the Commission seeks on-site demonstration projects, not laboratory-scale ones.
Who is supposed to apply and how much money is available?
Two-stage means two applications. Stage 1 is a brief proposal, evaluated anonymously (no names or logos). If you are invited, you then submit a complete second-stage proposal by 2 September 2027. Part B of the second stage has three extra pages for the business case and exploitation strategy.
What are the infections that are in scope?
Which four outcomes are the evaluators really seeking?
Two ranges. Medium- to low-temperature ranges (100 to 500 °C) require hybrid technologies, high-temperature heat upgrading, and fossil-fuel phase-out. Higher temperatures (above 500 °C) require electrified processes and high-temperature thermal energy storage. Both temperature ranges are covered.
In what way ought we to arrange the scientific work intelligently?
We suggest using a GHG avoidance approach with baseline descriptions. Your baseline must be credible, and the calculation clear. No claims will be reviewed if they are too vague. The reduction is calculated at the system level – the entire process in which the technology is used.
What is the microfluidics value-added in this case?
Demand-side management as such is explicitly excluded. The Commission does not care about renewable energy production scheduling. It is looking for solutions at the technology level: hardware, materials and integration.
What is the true competition of a consortium?
Two co-programmed partnerships: Processes4Planet and Innovative Advanced Materials for the EU. If your consortium already has partners involved in one of the partnerships, mark it. If not, the first step is to find out if any of your network members are.
What is strictly in and out of scope?
In the first instance, you eliminate all specific organizational information from your abstract and Part B. No names of institutions, no acronyms, no logos, no staff names. This is where consortia can get tripped up, as it isn’t always standard practice.
What are the pitfalls that usually destroy Health RIA proposals?
Starting at TRL 4/5 and ending at TRL 6/7. The project progresses from lab-based validated components to pilots on industrial sites. Have partners that can plausibly host the progression.
What do timelines and milestones show in terms of credibility?
An SME with engineering capability adds to credibility and efficiency. For materials testing, thermal testing, and pre-pilot testing, a microfluidics SME with expertise, such as the Microfluidics Innovation Center, can add value rather than simply add a name. Evaluators read role descriptions carefully.
