It’s been a good week for carbon capture projects in Europe with the announcement of who the European Union (EU) has selected for a grant from its Innovation Fund. 17 large-scale projects have been pre-selected for the Euro1.8bn being doled out in the second round of awards. On the cement and lime sector side there are four projects. These include projects at Holcim’s Lägerdorf cement plant in Germany, HeidelbergCement’s Devnya Cement plant in Bulgaria, Holcim’s Kujawy plant in Poland and Lhoist’s Chaux et Dolomites du Boulonnais lime plant in France. Large-scale in this instance means projects with capital costs over Euro7.5m. To give readers some sense of the scale of the projects that the EU has agreed to pay for, if the funding was shared out equally between the current bunch, it would be a little over Euro100m per project. This is serious money.

Devnya Cement’s ANRAV carbon capture, utilisation and storage (CCUS) project in Bulgaria has received little public attention so far so we’ll look a little more closely at this one first. No obvious information is available on what capture technology might be in consideration at the plant. HeidelbergCement’s leading experience in carbon capture technology at cement plants gives it a variety of methods it could use from a solvent scrubbing route to something less common. What the company has said is that, subject to regulatory approval and permitting, the project could start to capture 0.8Mt/yr of CO₂ from 2028.

What has also been revealed is that the project is linking up via pipelines to a depleted part of the Galata gas field site in the Black Sea. Oil and gas company Petroceltic Bulgaria is a partner and the aim of the project is to start a CCUS cluster in Eastern Europe. with the potential for other capture sites in Romania and Egypt to join in. This is noteworthy because much of the focus for the burgeoning cement sector CCUS in Europe so far has been on usage on local industrial clusters or storage in the North Sea.

The other new one is the Go4ECOPlanet project at Holcim’s Kujawy plant in Poland. Lafarge Cement is working with Air Liquide on the project. The latter will be providing its Cryocap FG adsorption and cryogenics technology for direct capture of flue gas at the plant. The transportation of the CO₂ is also interesting here as it will be by train not pipeline. Liquid CO₂ will be despatched to a terminal in Gdańsk, then transferred to ships before being pumped down into a storage field under the North Sea.

Turning to the other two grant recipients, the Carbon2Business project plans to capture over 1Mt/yr of CO₂ using a second generation oxyfuel process at Holcim Deutschland’s Lägerdorf cement plant. This project is part of a larger regional hydrogen usage cluster so the captured CO₂ will be used to manufacture methanol in combination with the hydrogen. Finally, Lhoist’s project at a lime plant in France is another team-up with Air Liquide, again using the latter’s Cryocap technology. The capture CO₂ will be transported by shared pipeline to a hub near Dunkirk and then stored beneath the North Sea as part of the D'Artagnan initiative. Around 0.61Mt/yr of CO₂ is expected to be sequestered.

The key point to consider from all of the above is that all of these projects are clear about what is happening to the CO₂ after capture. The days of ‘carbon capture and something’ have thankfully been left behind. CO₂ transportation infrastructure is either being used or built and these cement plants will be feeding into it. This will inevitably lead to questions about whether all these new CO₂ networks can support themselves with or without EU funding but that is an argument for another day.

Finally, in other news, four residents from the Indonesian island of Pulau Pari started legal proceedings against Holcim last week for alleged damages caused by climate change. Industrial CO₂ emissions are unquestionably a cause of this along with other sources but what a court might think about this remains to be seen. Yet, it is intriguing that the plantiffs have decided to go after the 47th largest corporate emitter rather than, say, one of the top 10. Regardless of how far the islanders get this is likely not to be last such similar attempt. If the case does make it to court though it seems likely that Holcim will mention its work on CCUS such as the two projects above. Only another 200-odd cement plants in Europe to go.

Boral admitted this week that high energy costs in Australia had forced it to reduce production levels. Chief executive officer Zlatko Todorcevski revealed to Reuters that the company was temporarily cutting back some unspecified areas of its operations. He also said that it was going to have to pass on growing energy prices directly on its customers.

This has followed mounting alarm at fuel prices in successive financial reports by the building materials company leading to revised earnings guidance being issued in May 2022. Bad weather was responsible for the larger share of the expected additional adverse impact to underlying earnings in its 2022 financial year but around US$10m was anticipated from rising fuel prices. Growing coal and electricity prices were said to be impacting its production and logistics costs, with price rises in January and February 2022 having proved insufficient to keep up with inflation. In a trading update in March 2022 the company said that its exposure to coal prices was unhedged for the second half of its 2022 financial year, to June 2022.

An energy crisis in Australia may seem hard to understand given that the country is one of the world’s biggest exporters of coal and gas. Yet, the country has faced a number of problems with its electricity generation sector in 2022 with disruptions to coal supplies to power stations, outages, ongoing maintenance and a cold winter that adversely affected the market. This led the Australian Energy Market Operator to suspend the country’s main wholesale market on 15 June 2022 in an attempt to stabilise the supply of electricity. New South Wales has also reportedly forced coal mines to prioritise the local market over exports. Energy minister Chris Bowen even asked the residents of New South Wales to try and reduce electricity use in the evenings in an attempt to prevent blackouts. However, with the consumer electricity market now looking more stable, attention has turned to industrial users such as Boral.

Global Cement Weekly has covered energy costs for cement producers a couple of times in the last year. There has been plenty of angst about growing energy costs on cement company balance sheets since mid-2021 as the logistics problems following the lifting of the coronavirus-lockdowns became clear. The biggest story at this time was an energy crisis in China that caused supplies to be rationed to industrial users. This then intensified with the start of the war in Ukraine in February 2022 and energy prices went up everywhere as economic sanctions were imposed upon Russia. One standout was Turkey where cement producers publicly raised the alarm about jumps in coal prices.

Recently, some North American lime producers such as Lhoist North America and the Mississippi Lime Company have been notably bold in announcing price rises due to energy costs and other factors. This week, for example, Lhoist North America said it had raised the price of its lime products by up to 45%. It cited the ‘challenging circumstance’ for all parties at an ‘unprecedented’ time. One alternative to the direct approach of simply putting up prices has been the use of energy surcharges. Japan-based Taiheiyo Cement announced earlier in June 2022 that it was going to introduce a coal surcharge for its cementitious products in September 2022 due to rising energy prices. Its system is based on the coal price with revisions planned every two months. The scheme will run for one year in the first instance. How customers will react to this remains to be seen.

We have looked above at a few disparate examples of the problems that energy costs have been causing cement and lime producers over the last month. These issues look set to continue in an acute phase while the war in Ukraine rages on, but the longer term trends from the economic recovery from coronavirus will undoubtedly last for longer. As examples in Australia and China have shown, local energy crises can easily spill over into the industrial sector as domestic users are prioritised. So, even if cement companies source their supplies carefully, they may face issues if the wider market struggles. Meanwhile, cement producers face the dilemma of justifying price rises to customers adapting to mounting inflation. Taiheiyo Cement has shown one way of doing this. The problems caused by surging energy prices to other cement companies look set to become more apparent in the next few months as reporting of the first half of the year emerges.

Canada/US: Lime company Lhoist North America raised the price of its lime products by up to 45% from 13 June 2022. The producer acknowledged the ‘challenging circumstance’ for all parties at an ‘unprecedented’ time. It said “We look forward to continuing to deliver the expected value to our customers.”

France: Lhoist and Air Liquide have signed a memorandum of understanding with the aim to build a carbon capture unit at Lhoist’s Réty lime plant in Hauts-de-France. Air Liquide wants to build and operate a unit from 2028 using its Cryocap FG (Flue Gas) technology to capture and purify 95% of the lime plant’s CO₂ emissions. The companies have jointly applied for the European Innovation Fund large scale support scheme to pay for the project. This partnership is a step towards the creation of a low-carbon industrial ecosystem in the Dunkirk area.

Lhoist’s ‘Chaux et Dolomies du Boulonnais’ plant in Réty is France’s largest lime production plant. A potential carbon capture unit at the plant could potentially reduce the CO₂ emissions of the plant by more than 600,000t/yr. Captured CO₂ would then be transported to a multimodal CO₂ export hub in Dunkirk, currently under development, and sent to be sequestered in the North Sea as part of the D’Artagnan project, which has received the PCI (Project of Common Interest) label from the European Commission. The implementation of the project will be possible as public funding from European and/or French schemes supporting decarbonisation become available.

US: Lhoist North America and Mississippi Lime Company have announced price increases for their products subject to existing contractual obligations.

Lhoist North America increased its prices by 10% for lime, limestone and clay products from the start of April 2022. It blamed this on inflation upon the cost of chemical additives, electricity, explosives, diesel, mining equipment, spare parts, inbound transportation, mining services and other inputs.

Mississippi Lime Company has announced that it will increase its prices by 7% from the start of May 2022. It cited a combination of market demand, inflation and supply chain issues.

In the two and a half years since Calix brought together cement producers across corporate and national boundaries to form the first Low Emissions Intensity Lime And Cement (LEILAC-1) consortium and commissioned a carbon capture installation at the Lixhe cement plant in Belgium on 10 May 2019, carbon capture and storage (CCS) has passed some major milestones. New installations have made Global Cement headlines from Canada (at Lehigh Cement’s Edmonton plant in November 2019) to China (at a China National Building Material (CNBM) plant in July 2021). Twelve other European cement plants now host current or planned carbon capture trials – including the first full-scale system, at HeidelbergCement’sBrevik plant in Norway. A second Calix-led project in Germany, LEILAC-2, attracted Euro16m-worth of funding from the European Union in April 2020.

The work of LEILAC-1 – backed by HeidelbergCement, Cemex, Lhoist, Tarmac and others, with Euro12m in funding – set the benchmark in innovation. Its pilot plant successfully captured 100% of 'unavoidable' process emissions by indirectly heating raw materials inside a vertical steel tube. Called direct capture, the model removes a CO₂ separation step, as our subsequent price analysis will reflect.

In October 2021, the LEILAC-1 consortium published its report of the concluded Lixhe trial. It described the three-fold key successes of the study:

1) Both limestone and raw meal may be processed;

2) CO₂ is successfully separated;

3) The energy penalty for indirect calcination is not higher than for conventional direct calcination.

Additionally, Calix’s first departure into the cement sector has demonstrated that its model exhibits no operational deterioration, does not suffer from material build-up and has no impact on the host plant when used in cement production. The plant’s clinker capacity remained the same as before the trial. Most importantly of all, the Lixhe cement plant recorded no process safety incidents throughout the duration of the trial.

The study has also put an evidence-based price tag on industrial-scale CCS at a cement plant for the first time: Euro36.84/t. Figure 1 (below) plots the full-cycle costs of three different carbon capture installations at retrofitted 1Mt/yr cement plants using 100% RDF, including projections for transport and storage. Installation 1 is an amine-based carbon capture system of the kind installed in the Brevik cement plant’s exhaust stack; Installation 2 is the Calix direct capture system and Installation 3 consists of both systems in combination. Direct capture’s costs are the lowest, while the amine retrofit and the combination installation are close behind at Euro43.68/t and Euro43.25/t respectively.

Figure 1: Full-cycle costs of three different carbon capture installations at retrofitted 1Mt/yr cement plants using 100% RDF

Installations 1 and 3 both entail additional energy requirements for the separation of CO₂ from flue gases and air. With the inclusion of the CO₂ produced thereby, the cost of Installation 1 rises to Euro94/t of net CO₂ emissions eliminated, more than double that of Installation 2 at Euro38.21/t. The combination of the two in Installation 3 costs Euro67.3/t, 76% more than direct capture alone. Figure 2 (below), breaks down the carbon avoidance costs for each one and compares them.

The Global Cement and Concrete Association (GCCA)’s seven-point Roadmap to Net Zero strategy puts CCS at the forefront of concrete sector decarbonisation. CCS is expected to eliminate an increasing share of global concrete’s CO₂ emissions, rising to 36% in 2050 – by then 1.37Bnt of a total 3.81Bnt. This will depend on affordability. Calix’s model has reduced the capital expenditure (CAPEX) of a carbon capture retrofit by 72% to Euro34m from Euro98m for the amine-based equivalent. When built as part of a new plant, the CAPEX further lowers to Euro27m. Both models may also be retrofitted together, for Euro99m. In future, Calix expects to install direct capture systems capable ofachieving Euro22/t of captured CO₂. By contrast, the cost of emitting 1t of CO₂ in the EU on 11 October 2021 was Euro59.15.

In what it calls the Decade to Deliver, the GCCA aims to achieve a 25% CO₂ emissions reduction in global concrete production between 2020 and 2030, in which CCS plays only a minor part of less than 5%. LEILAC-1 presents a visionof affordable carbon avoidance which complements cement companies’ 2030 CO₂ reduction aspirations.

Unlike conventional CCS methods, however, direct capture only does two thirds of a job – eliminating the emissions of calcination, but not combustion. This would appear to make it unsuited to cement’s longer-term aim of carbon neutrality by 2050 in line with the Paris Climate Accords’ 2°C warming scenario. On the other hand, direct capture is not designed to work alone. Calix recommends use of the technology in conjunction with a decarbonised fuel stream to eliminate the plant’s remaining direct emissions. This increases the price - by 47% to Euro56.05/t of CO₂ avoided for biomassand by more than double to Euro104.48/t for an E-kiln.

The Lixhe cement plant’s carbon capture story is one of a successful crossover from one industry into another: Calix previously applied the technology in the Australian magnesite sector. Realisation of the Calix carbon capture vision in the global cement industry is a challenge primarily due to the scale of the task. It will require continued collaboration between companies and with partners outside of the industry. Further than this, parliaments must continue to enact legislation to make emission mitigation the economic choice for producers.

US: Lhoist will raise the price of its lime products by US$0.2/t for every US$0.05 rise in its natural gas costs above US$2.6/MMBtu from 1 November 2021. The producer says that the price rise reflects supply challenges and increased costs, of which energy costs have risen most significantly.

The producer said “We regret having to implement this energy surcharge, but believe it necessary in the face of these energy-related cost increases. Additionally, please note that this surcharge is independent of and in addition to 2022 price increases that will be necessary for Lhoist to keep pace with general inflationary factors impacting its cost structure.” It added “We appreciate your business and cooperation during this difficult time. If you have any questions regarding the above, feel free to contact your Lhoist sales representative.”

US: Lhoist and Maerz Ofenbau have started up a lime kiln at the Montevallo plant in Alabama. The R4S type PFR kiln supplied by Switzerland-based Maerz Ofenbau has a nominal production rate of 600t/day of lime and is able to fire gas and coal.

Germany: Lhoist has taken advantage of the alkaline soils around its Istein, Baden-Württemberg quarry in producing a range of six white wines, two red wines and a rosé under its Kalkweingut label. The grapes are grown on reclaimed sections of the quarry and harvested between August and October. The company says that the limestone ‘has a high nutritional value and retains the warmth of the Sun,’ which, in conjunction with the warm climate of South Baden, gives the wines a ‘Mediterranean’ expression.

US: The Texas Commission on Environmental Quality (CEQ) has granted permission to Lhoist North America for the installation of a new vertical kiln at its New Braunfels, Texas plant. The company says that the kiln will form the basis for a plant expansion to meet the growing lime demand of the construction and steel sectors.

Lhoist North America chief executive officer (CEO) and president Ron Thompson said, "We are proud that this investment at New Braunfels aligns with our company's commitment to environmentally sustainable growth."
