Introduction

As shown in CEMBUREAU’s Net Zero Roadmap update , Carbon Capture, Utilisation and Storage (CCUS) is critical to decarbonise cement production. Significant investments are currently ongoing in the cement industry in this respect¹: whilst today, the majority of carbon capture projects in the EU cement sector aims at capturing the CO₂ and storing it geologically (CCS), the sector is also looking at the utilisation of CO₂ in products (CCU). CCU is indeed vital for many EU cement kilns which are landlocked and not located next to CO₂ storage sites. Through CCU, the cement sector can provide a significant stream of concentrated CO₂ for use in various sectors of the economy, allowing to decarbonise and cut the EU’s reliance on fossil fuels²

Mineralisation is a permanent form of CO₂ storage

The cement and concrete industries have been looking at the potential of mineralisation for some time. Significant research has gone into the topic³ and an increasing number of companies – some of them outside the cement sector – are aiming at storing CO₂ in concrete or aggregates, sometimes even offering carbon removals through the use of biogenic CO₂ .

As evidenced in our previous position paper⁴, the permanence of CO₂ storage through mineralisation is well-established. We therefore welcome the recognition by the draft Delegated Act that mineralisation through construction products is a permanent form of storage.

The Delegated Act is overly prescriptive when it comes to other forms of ‘permanent’ CCU

However, CEMBUREAU believes that the draft Delegated Act is overly restrictive, in that it sets a requirement that “CO₂ should remain permanently chemically bound in a product for at least a period of several centuries or longer”, which de facto prohibits any other type of long-term storage in other types of products (e.g. chemical products), even when these would be part of a recycling loop. CEMBUREAU considers that, provided chemical products are part of a recycling loop, the putting of CO₂ in chemicals should be considered as permanent storage. As an example, it is CEMBUREAU’s strong view that if plastics are appropriately recycled (with clear obligations for the manufacturer), using captured CO₂ to produce them should be considered as permanent chemically bound use.

‘Non-permanent’ CCU in the revised ETS Directive

Last but not least, CEMBUREAU would like to stress that whilst the Draft Delegated Act provides a degree of clarity on what constitutes a permanent CO₂ storage in product, it is critical that the EU CCU framework is swiftly reviewed to provide a business case for investments.

In particular, the updated ETS Directive considers that, in the case of ‘non-permanent’ CCU, the capturing installation (rather than the installation/entity actually emitting the CO₂ ) should surrender allowances, even if the capturing installation is not releasing the CO₂ in the atmosphere. In our view, CO₂ allowances should be surrendered by the ‘emitter’ of the CO₂ contained in a CCU product, and not by the capturing installation. The CO₂ accounting needs to be done at the point where CO₂ is released into the atmosphere. CEMBUREAU notes that the ETS Directive foresees a review clause to ‘assess the accounting’ of CO₂ used in non-permanent CCU applications⁵. It is in our view very important that this clause is taken up in the future review of the ETS, in light of the expansion of the ETS to other sectors (full aviation coverage, waste incineration, etc.), which should allow to account emissions at the point of release.

Furthermore, CEMBUREAU wishes to highlight the urgency of reviewing provisions of the Draft Regulation setting out a methodology for GHG emission savings from renewable fuels of nonbiological origin (RFNBOs) and recycled carbon fuels (RCFs). The act, in its current form, considers that CO₂ emissions from industrial sources will no longer be considered as avoided for RFNBOs production past 2040. This has de facto halted CCU projects in the European cement industry. It is urgent that to a review of this date, as foreseen in []recital5 of the Delegated Act .
