Biggest Dutch project for CO₂ reduction, Porthos, is on schedule

Porthos, the project for CO₂ capture and storage in Rotterdam, is on schedule to store an annual amount of 2.5 million tonnes of CO₂ from the industry in empty gas fields beneath the North Sea as from 2024. By the end of last year, four companies registered for a total of €2 billion from the SDE++ scheme for the next 15 years. The final sum may be considerably lower, especially due to the rising price of emission rights (ETS) in the next 15 years. Capture and storage of CO₂ (Carbon Capture and Storage, CCS) is one of the cheapest ways to meet the climate targets in the short term.

Between 2008 and 2019, a total of approximately €4.5 billion in SDE funds was paid to many projects in the Netherlands. Because of these projects about 42 million tonnes of CO₂ less has ended up in the atmosphere[1]. With even less than half the sum, the Porthos project will realise an almost equally big reduction: some 37 million tonnes of CO₂ in a 15-year period. It is clear that CCS is the best way forward to make huge progress fast and relatively cheaply in meeting the climate targets. It is set out in the Dutch Climate Agreement that half of the industry’s CO₂ reduction in 2030 will be achieved by CCS. As to the other half, the industry concentrates on efficiency, electrification, solar and wind farms, and green hydrogen. For many industry processes, however, there are not enough ways to reduce CO₂ emissions drastically in the short term.

It is expected that the subsidy will be granted to the four companies (Air Liquide, Air Products, ExxonMobil, and Shell) next spring. According to expectations, the permit procedures will be completed by late 2021. The companies will use 2021 especially to prepare for the construction of the capture plants. This year, the Porthos project organisation (EBN, Gasunie, Port of Rotterdam Authority) will be working on the technical preparations of laying pipes on land and on the sea bed, building the compressor station, and adjusting the platform at sea. The final investment decision for Porthos has been planned for 2022, after which the realisation can proceed.

Major developments last year included submission of the Environmental Impact Assessment (EIA) and several permit applications, making arrangements between Porthos and the four companies that want to use the Porthos system, and the European Union promise to contribute €102 million to the project.
