HeidelbergCement released their sustainability report for 2019 this week. Every large cement producer publishes one but this one is worth checking out because of the company’s ambition to become CO₂ neutral. Other companies are heading the same way but few of them have such developed and public plans.

Sustainability reports are often a hodgepodge of non-financial reporting bringing together environment, health and safety, community and other topics. Multinational companies cover a wide range of jurisdictions and combining reporting in these kinds of fields can be beneficial. Typically they are members of various bodies like the Global Reporting Initiative (GRI) or the Global Cement & Concrete Association (GCCA) that give various levels of conformity between reports. Yet, the wider focus of sustainability reports gives companies a chance to promote what they are doing well, away from balance sheets.

One highlight of HeidelbergCement’s report is its progress towards reducing its specific CO₂ emissions per tonne of cement and its recognition by the Science Based Targets (SBT) initiative towards this goal. So far it has achieved a reduction of around 22% from 1990 levels to 599kg CO₂/t (net) with a target of a 30% reduction or 520kg CO₂/t by 2030. There is a lot more going on in the report but it’s led by the vision, ‘to offer CO₂-neutral concrete by 2050 at the latest.’ It plans to achieve this by increasing the proportion of alternative CO2-neutral raw materials and fuels, developing lower clinker cement types and capturing and utilising CO₂ emissions. A focus on concrete is worth noting given the pivot by building materials manufactures towards concrete in recent years.

Back in the present, HeidelbergCement is roughly in the middle of the pack of major European multinational cement producers with its specific CO₂ emissions for cement in 2019. LafargeHolcim reported 561kg CO₂/t and Cemex reported 622kg CO₂/t. This is a bit of a moving target since corporate acquisitions and divestments can change both the starting point and the apparent current progress. HeidelbergCement’s acquisition of Italcementi in 2017 or CRH’s purchase of Ash Grove did exactly that. The other thing to consider is that these companies manufacture a lot of cement. The actual gross CO₂ emissions from a multinational cement producer are immense. LafargeHolcim, one of the world’s largest multinational producers, emitted 113Mt of CO₂ in 2019 from process and fuel sources whilst making cement. To put that into context, estimates for total global CO₂ emissions range from 33 – 36Gt for 2019. The cement industry’s entire share was estimated by the International Energy Agency (IEA) to be 4.1Gt in 2018.

Where this sustainability report starts to become really interesting is where it talks about CO₂ capture and utilisation. Its plans in this department are more mature than many of its competitors with various initiatives at different levels of development, mostly in Europe. Norcem, its Norwegian subsidiary, recently signed an agreement with Aker Solutions to order a CO₂ capture, liquification and intermediate storage plant at its integrated Brevik cement plant. The deal is dependent on government support but it’s a serious proposal. As reported previously from the Innovation in Industrial Carbon Capture Conference 2020, HeidelbergCement is actively preparing to hook up with CO₂ transport and storage infrastructure. The driver is CO₂ pricing from initiatives like the European Union (EU) Emissions Trading Scheme (ETS). With the EU preparing for the next phase of the ETS and talk of the European Green Deal gathering pace, before the coronavirus outbreak at least, CO₂ prices in Europe look set to rise. HeidelbergCement is positioning itself to benefit from being the first major cement producer to head into CO₂ capture and storage/utilisation with a variety of methods intended for different CO₂ prices and regional requirements.

HeidelbergCement doesn’t mention the coronavirus pandemic in its latest sustainability report. The report covers 2019 after all, before all of this happened. These reports do include health and safety information of employees, so this may be something to look out for next year. However, Cemex did mention the coronavirus in relation to its climate action plans this week. Essentially it wants to maintain its plans as a ‘fundamental component’ of its efforts to recover from the health crisis. This chimes with media talk around so-called ‘green-led’ government-backed relief programmes. Governments are the ones who are likely to be handing out the money, probably in the form of infrastructure projects. So it’s the perfect opportunity for them to encourage change from the companies bidding for this funding. Sustainability reports and the information behind them will be a useful tool in accessing this cash.

Norway: Norcem, a subsidiary of HeidelbergCement, has signed an agreement with Aker Solutions to order a CO₂ capture, liquification and intermediate storage plant at its integrated Brevik cement plant. The final decision for the project depends on funding from the Norwegian government, which is expected to approve the unit in its national budget for 2021.

The project will use Aker Solutions’ Advanced Carbon Capture (ACC) technology and its S26 amine solvent. Once complete the unit will capture 0.4Mt/yr of CO₂. This will be transported to the Northern Lights project for permanent storage offshore beneath the North Sea.

Norway: Norcem, part of HeidelbergCement Group, has awarded a contract for a concept study of carbon capture at its Brevik cement plant to Aker Solutions. It previously carried out testing with a pilot capture plant at Brevik. Norcem subsequently selected Aker Solutions' technology to be used for a potential facility at the cement plant. The oil and gas engineering company has also won a carbon capture contract from Yara to run a study at its Herøya ammonia plant.

"Aker Solutions can now offer carbon capture plants at lower costs and with less energy demand using a new non-corrosive and environmentally-friendly solvent that has very low degradation," said Oscar Graff, head of carbon capture and storage (CCS) at Aker Solutions. "The solvent is very robust and can be used for various types of flue gases and gives minimum emissions and waste products."

The study for Norcem will design a carbon capture plant that's integrated with the cement factory, including a process to turn the CO₂ into liquid and storage facilities that can be used before shipping. The plant will have a capacity of about 400,000t/yr of CO₂. The Yara study will design and develop a capture plant for the reformer flue gas and will also include liquefaction. Both concept studies are set to be completed in September 2017.

In April 2017 Gassnova, a state-run company for carbon capture and storage, announced the start of the concept studies as part of a goal to establish a complete CCS chain, including capture, transport and permanent storage, by 2022. The concept phase will also seek to establish more accurate cost estimates. The next phase in the process will involve front-end engineering design (FEED) work until around mid-2018 before an investment decision is made by the Norwegian government in the first half of 2019.

Aker Solutions has developed and qualified an improved carbon capture technology since 2008, investing in research and development, testing and operations. The company has gathered experience through design, construction and two years of operations of an amine plant at Technology Centre Mongstad and carried out tests in the US, the UK and Norway using its mobile carbon capture pilot plant.

Norway: Oil and gas industry engineering firm Aker Solutions has won a contract to test and study the capture of CO₂ from flue gas emitted at Norcem's cement plant in Brevik, Norway. The award from the HeidelbergCement subsidiary, in cooperation with the European Cement Research Academy (ECRA) marks the first time technology to capture CO₂ will be used at a cement production plant.

Aker Solutions will perform long-term testing on the actual flue gas to select optimum chemical solvent for high content CO₂ flue gas at the plant. Tests will be performed with Aker Solutions' in-house developed Mobile Test Unit (MTU). The MTU is a CO₂ capture plant that includes all processes and functions found in a large scale commercial plant.

ECRA members chose Norcem Brevik as the site for ECRA operational CO₂-capture test project. The project is supported and partly financed by the CLIMIT programme, which is managed by Gassnova in cooperation with the Research Council of Norway.

Aker Solutions has developed CO₂-technology solutions since the early 1990s. A separate company, Aker Clean Carbon, was established in 2007 as a company under Aker ASA to commercialise carbon capture technology. Aker Solutions took full ownership of Aker Clean Carbon in 2012 and carbon capture and storage activities are an integrated part of Aker Solutions.
