The circular transformation of industry includes not only the material transformation but also the energy transformation (by switching to carbon-free energy sources). In many areas of the medium-sized process heating industry, hydrogen is the logical substitute for natural gas, so many applications could be converted relatively quickly. ZINQ is involved in the Klimahafen Gelsenkirchen - an association of companies from the city port of Gelsenkirchen and its immediate neighborhood as well as institutions that actively support the transformation of the economy towards climate neutrality in Gelsenkirchen and the surrounding area.
