INEOS Inovyn becomes Europe’s first green hydrogen ISCC PLUS fully certificated producer

INEOS Inovyn is the largest operator of electrolysis technology in Europe, producing 60,000 tonnes of low-carbon hydrogen annually across multiple sites

  • INEOS Inovyn’s Antwerp hydrogen production, has been certified under the ISCC (International Sustainability & Carbon Certification) PLUS scheme.
  • We become the first European company to have our renewable hydrogen fully audited with greenhouse gas data certification.
  • “This demonstrates our commitment to providing industry leadership and strengthening Europe’s renewable hydrogen production. It allows our customers to calculate their own product footprints, enabling them to market lower carbon products.” said Wouter Bleukx, Business Director Hydrogen at INEOS Inovyn.

We have achieved a new ISCC certification, reflecting our ambition to reduce carbon emissions. From June 2023, hydrogen production at the group’s Antwerp site is now certified under ISCC PLUS – a global voluntary certification program for bio-based, circular and renewable raw materials across all markets.

It makes INEOS Inovyn the first certified company in Europe to have its required greenhouse gas data fully audited, providing added value to customers by enabling the traceability of sustainable materials along supply chains. Customers using our renewable hydrogen will now be able to develop sustainable downstream products which benefit from this certification – along with reducing their Scope 3 emissions.

Our Antwerp site produces hydrogen through Chlor-Alkali electrolysis – the electrolysis of brine producing chlorine, caustic soda/potash, sodium hypochlorite and hydrogen. The electricity used to produce this hydrogen comes directly from wind turbines off Belgium’s North Coast.

“We use renewable electricity from existing and local Power Purchase Agreements to produce renewable hydrogen. I’m proud that our hydrogen is now labelled renewable-energy-derived material and hope this drives the market towards greater sustainability.”

“Hydrogen produced from the Chlor-Alkali industry is vital as the European hydrogen market grows, this ISCC PLUS certification means there is only one product on the market today with robust and transparent sustainability credentials,” explains Wouter Bleukx.

Using our expertise in production, technology and storage, we are helping pioneer changes that will grow European hydrogen production.
