The industrial gas major revealed on LinkedIn the first prefabricated modules arrived via charter vessel and were transported to ExxonMobil’s refinery for installation.

They will be equipped to Air Products’ 300-tonne-per-day HyCO4 plant to capture “more than half” of its carbon dioxide emissions from the process side for the steam methane reformer.

CO2 will be transported using the Porthos infrastructure for permanent storage in the North Sea.

The project was announced in 2023 and is due to come online in 2026.

While the project will not produce hydrogen that can be classified as “low-carbon” under the EU’s definition, it will reduce the site’s emissions trading scheme (ETS) bill.

Speaking to H2 View after the project was announced, Mark van Wijk, Air Products Director of Large Projects Business Development, said the growing ETS price had become a “very effective motivator.”

With around 100 million tonnes of existing, unabated hydrogen production worldwide, contributing around 2.5% of global CO2 emissions, cleaning up existing plants could go a long way to supporting emissions reduction targets.
