The consumption of 4.6 million tonnes of hydrogen yields 46 million tonnes of CO2 reduction, and it increases Europe’s energy independence. This hydrogen amount is the total the Port of Rotterdam Authority has come up with on the basis of specific projects and realistic plans, which companies and exporting countries are now working on. On behalf of some 70 companies and exporting countries, the Port of Rotterdam Authority has made European commissioner Frans Timmermans this offer of getting off to a flying start with the hydrogen economy.The plans and projects represent a concrete implementation of the heightened European ambition: within the context of REPowerEU, a fourfold increase is envisioned in the production and import of hydrogen compared to the ‘Fit for 55’ package (from 5.6Mt to 20Mt). This hydrogen could then be used for ensuring the sustainability of society, in particular as fuel and feedstock for transport and industry.According to the 70 parties that endorse the offer, two preconditions are crucial to get the hydrogen economy underway. The first is hydrogen certification: green hydrogen imported from outside Europe has to be certified as green here. The second precondition is closing the financial gap between the use of renewable and low carbon hydrogen and its derivatives compared to their current CO2-emitting alternatives. This is because as long as energy made from fossil fuels is cheaper than sustainably produced energy, the latter will not get the momentum required for achieving the European objectives.
