Iberdrola Clientes' GRHENA project — a green industrial-heat generation hub at the Chemical Industrial Park of Tarragona, Spain, designed to produce up to 648 GWh/year of steam via electric boilers powered by renewable electricity — was awarded a EUR 53,938,146 (~USD 63.5 million) grant under the European Commission's Innovation Fund. The Grant Agreement was signed on 22 July 2025 as part of a batch of six Innovation Fund 2023 general-call projects (worth EUR 319 million combined) that collectively target 24.1 million tonnes of CO2-equivalent avoided over their first ten years of operation. GRHENA is described as the first large-scale demonstrator of direct industrial electrification of heat generation, replacing natural gas at the Tarragona chemical complex.

Mechanism

GRHENA (Green heat generation hub at the Chemical Industrial Park of Tarragona) is a project developed by Iberdrola Clientes Sociedad Anonima, one of six Innovation Fund 2023 general-call projects to sign Grant Agreements with CINEA (the European Climate, Infrastructure and Environment Executive Agency) on 22 July 2025. The project deploys electric boilers powered by renewable electricity to directly electrify industrial steam generation at the Tarragona chemical polygon, displacing natural gas combustion. It is positioned as the first large-scale demonstrator of this direct electrification pathway for industrial heat, with a design capacity of up to 648 GWh/year of steam output. The EUR 53,938,146 grant is non-dilutive EU funding disbursed against milestone delivery under the Innovation Fund's standard grant-agreement terms.

The six-project batch signed on 22 July 2025 (EUR 319 million combined) spans hydrogen, hydro/ocean energy, energy storage and refinery-decarbonisation technologies, of which GRHENA is the industrial-heat-electrification component.

Downstream implications

Industrial electrification precedent: as a first-of-kind large-scale

demonstrator, GRHENA's technical and cost outcomes will inform whether direct electric-boiler retrofits become a template for decarbonising gas-intensive chemical clusters elsewhere in the EU.

Iberdrola capex de-risking: adds to Iberdrola's growing portfolio of

non-dilutive EU Innovation Fund awards (alongside Project NOON hydrogen and offshore-wind EIB financing), reducing the equity cost of its Spanish decarbonisation pipeline.

Tarragona chemical cluster: reduces natural-gas dependency for a major

Spanish petrochemical hub, with second-order relevance for gas-demand forecasts in the region.

Open questions

Construction timeline and expected commercial-operation date for the

Tarragona hub were not disclosed in the primary source reviewed.

Whether GRHENA's steam output is contracted to specific chemical-plant

offtakers within the Tarragona polygon or sold on a shared-infrastructure basis.
