IS2H4C

IS2H4C project focuses on deploying systemic industrial symbiosis through innovative technologies like carbon capture and electrolysis. The initiative is driven by the vision of resource efficiency, renewable energy production, waste prevention, and fostering industrial-urban-rural symbiosis.

The project aims to develop the most innovative sustainable technologies and infrastructure integration in four demo hubs and is supported by ground-breaking research on societal, governmental, and business innovation for H4C. IS2H4C scales up industrial areas to H4C via implementing systemic change and integrating the surrounding ecosystems to industrial areas.

IS2H4C will implement its innovative model in four key hubs across Europe:

BIH4C – Basque Hub

The Basque Hub contains oil refining, steel, pulp and paper and lime industries, and the public wastewater treatment plant located in the highly industrialized area of the Basque Country. 

I. Oxycombustion with O2 and H2 in the steel industry.

II. CO2 via carbon capture (CC) by the lime industry and used (CCU) to produce CH4 (and potentially for the forthcoming production of e-fuels in the oil sector).

III. Carbonation of steel slags with the CO2 obtained from the lime industry (CCU) to produce construction products for the cement industry.

Izmir-Manisa – Turkish hub

Izmir-Manisa area contains oil refining and household appliances companies, located near an industrialized port area on the Aegean coast. 

I-II. Green H2 obtained from electrolysis and captured CO2 from oil refining activities via CC adsorption technology are used for e-methanol production.

III-IV. Captured CO2 is also used in the production of non-isocyanate polyurethane (NIPU) which substitutes traditional polyurethane in the production of refrigerators.

Twente – Dutch hub

The Twente area contains a small-scale hydrogen hub formed by approximately 20 process industry companies connected to a nearby village, Aadorp, which is planned to evolve into a positive energy district via becoming independent from natural gas and fossil-based electricity. 

 I-III. Green H2 is used in five houses in built environment in Aadorp via (to-be-implemented) H2 pipelines.

IV. Energy storage is implemented to stabilize the feed of the green energy generation.

V. H2 is transported to three crematoria in Twente by H2 tube trailers & substitutes for natural gas.

VI-VII. O2 from electrolysis will be sent to the wastewater treatment unit for water purification & treated water will be sent to electrolyser for H2 production. 

Industriepark Höchst – German hub

The Industriepark Höchst in Frankfurt am Main is the location for industry in the fields of pharmaceuticals, biotechnology, basic and specialty chemicals, crop protection, food additives, and services.

I-II. CO2 obtained from CC technology implemented in a power generation unit and H2 obtained from existing electrolysis (facilitating industrial waste heat use) are both used in e-methanol production.
