Each one links to its EU funding record and the partners it works with: a starting list for building a consortium.
Project results are expected to contribute to all of the following expected outcomes:
This topic aims to satisfy the need for process heat in the more industrial sectors by upgrading excess/waste heat from the process itself, possibly combined with heat recovered in nearby locations or local renewable heat, as a cost-efficient way to improve energy efficiency and reduce the GHG emissions and air pollutants and the use of fossil fuels. Thermal and/or electrical energy storage can be integrated, if it can contribute to better matching heat sources with process needs and/or to offer more flexible electricity consumption from the grid.
The temperature of the heat supplied to the process is not specified, but the proposals will be evaluated on their potential to enable the deployment of heat upgrade solutions in more sector(s) and process(es), where they are not yet state-of-the art.
Projects must address all the following items:
Technology Readiness Level - Technology readiness level expected from completed projects
Activities are expected to achieve TRL 7-8 by the end of the project – see General Annex B. Activities may start at any TRL.

Applicants asked the EU 3 questions about this call and the EU published the answers. They clarify the call documents but do not replace them.
The “Full-scale” specified in the title “Full-scale demonstration of heat upgrade solutions in industrial processes” is developed in the objective “increase the recovery and upgrade of locally available heat for covering process needs and significantly or totally phasing out of fossil fuel use” and the specified TRL 7-8. This means that the project should not be limited to a pilot demonstration covering a small portion of heating needs, but should include full-scale or industrial-scale equipment and system that, ideally, completely replace the use of fossil fuels. If not completely, a least a significant portion of the heat produced from fossil fuels must be replaced by the new system, and full coverage should be achievable by duplicating the equipment physically demonstrated in the project, without major modifications to its design. This would be particularly true with standardized modular equipment (for example, a heat pump), several units of which can be connected in parallel to reach the required total heating power.

Innovative integration of mature heat upgrade technology into an improved solution that enables “covering process needs and significantly or totally phasing out of fossil fuel use, while preserving or enhancing its global competitiveness” is eligible.

The topic specifies: “Optimise and demonstrate physically within one or more operational industrial site(s), the transformation of process(es) in at least one industrial by recovering excess/waste heat from the process itself, possibly combined with local renewable heat or heat recovered in nearby locations and local thermal and/or electrical energy storage, and by upgrading the heat (e.g. with heat pump) for use in the process(es).” It means at least part of the recovered heat must come from at least one of the (sub-)processes of the targeted industrial site itself, this recovered heat can be combined with other internal or external sources, possibly from an industrial or district heat network, then upgraded, finally used in at least one the (sub-)process(es) of the same industrial site. The expected outcome “for covering process needs and significantly or totally phasing out of fossil fuel use”, excludes any significant import of waste heat recovered from another industrial plant or heating system using fossil fuel.
