Norway: Private accreditation body DNVGL has certified Aker Solutions’ 400,000t/yr carbon capture and storage (CCS) system installation at Germany-based HeidelbergCement subsidiary Norcem’s 1.2Mt/yr integrated Brevik plant in Telemark as safe. HeidelbergCement Northern Europe director of sustainability and alternative fuels Per Brevik said, “The promising results from pilot testing in Brevik give us confidence that realisation of the full-scale capture plant will be successful. We trust that the project risk related to novel technology elements is low.”

Following an 18-month test of the partial installation, the certification ensures that the full-scale project will receive government funding.

Japan: Taiheiyo Cement has partnered with JFE Steel and the Global Institute for Environmental Technology to develop a carbon capture and storage system. The system will use wet alkaline earth metals extracted from steel slag to produce carbonates from exhaust gases at cement and steel plants. The partners are investigating the possibility of using these carbonates, specifically calcium carbonate and magnesium carbonate, as additives in cement production at Taiheiyo Cement’s plants. Taiheiyo Cement president Masafumi Shigehara said, “With the effects of climate change becoming apparent both in Japan and overseas, the importance of global warming counter-measures is increasing.”

Europe: Australia-based Calix has announced that construction will begin on its second low emissions intensity lime and cement (Leilac) carbon capture and storage (CCS) installation at a ‘European cement plant’ on 7 April 2020. ASX ComNews has reported that collaborators on the project, which has received Euro16m under the EU’s Horizon 2020 grant scheme, are Portugal-based Cimpor, Germany-based HeidelbergCement, Germany and France-based energy companies Ingenieurbüro-Kühlerbau-Neustadt (IKN) and Engie and Belgium-based minerals and lime company Lhoist. Calix has said that the 100,000t/yr process emissions capture facility will be operational in late 2024.
The company has appointed Emma Bowring Leilac-2 project leader.

The first Leilac installation was completed at HeidelbergCement’s 1.5Mt/yr integrated Lixhe plant in Belgium’s Limburg province in mid-2019.

The Coronavirus Disease 2019 (COVID-19) took on direct implications for the international cement industry this week when an Italian vendor infected with the virus visited Lafarge Africa in Ogun state, Nigeria. The cement producer said that it had ‘immediately’ started contact tracing and started isolation, quarantine and disinfection protocols. This included initiating medical protocols at its Ewekoro integrated plant, although local press reported the unit’s production lines were still open. Around 100 people were thought to have had contact with the man.

Global Cement has been covering the epidemic since early February 2020 when the virus’ effect on the construction industry in China started to become evident. First, an industry event CementTech was postponed, financial analysts started forecasting negative financial consequences for producers and plants started going into coronavirus-related maintenance or suspension cycles. Then at least one plant started to dispose of clinical waste and now China National Building Material Group (CNBM) is considering how to restart operations at scale. Also, this week Hong Kong construction companies reportedly laid off 50,00 builders due to a lack of cement due to the on-going production suspension in China.

The major cement companies have identified that their first business risk from coronavirus comes from simply not having the staff to make building materials. LafargeHolcim’s chief executive officer Jan Jenisch summed up the group’s action in its annual financial results for 2020 this week when he said, “We are taking all necessary measures to protect the health of our employees and their families.” Other major cement producers that Global Cement has contacted have placed travel restrictions for staff and reduced access to production facilities.

The next risk for cement companies comes from a drop in economic activity. The Organisation for Economic Co-operation and Development (OECD) forecasts a global 0.5% year-on-year fall in real gross domestic product (GDP) growth to 2.4%, with China and India suffering the worst declines in GDP growth at around 1%. The global figure is the worst since the -0.1% rate reported by the International Monetary Fund (IMF) in 2009. The OECD blamed the disease control measures in China, as well as the direct disruption to global supply chains, weaker final demand for imported goods and services and regional declines in international tourism and business travel. This forecast is contingent on the epidemic peaking in China in the first quarter of 2020 and new cases of the virus in other countries being sporadic and contained. So far the latter does not seem to have happened and the OECD’s ‘domino’ scenario predicts a GDP reduction of 1.5%. All of this is likely to drag on construction activity and demand for cement and concrete for some time to come.

Moving to cement markets and production, demand is likely to be slowed as countries implement various levels of isolation and quarantine leading to reduced residential demand for buildings directly and as workforces are restricted. Business and infrastructure projects may follow as economies slow and governments refocus spending respectively.

The UK government, for example, is basing its coronavirus action plan on an outbreak lasting four to six months. This could potentially happen in many countries throughout 2020. This has the potential to create a rolling effect of disruption as different nations are hit. Assuming China has passed the peak of its local epidemic then its producers are likely to report reduced income in the first quarter of 2020. The effect may even be reduced somewhat due to the existing winter peak shifting measures, whereby production is shut down to reduce pollution. Elsewhere, cement companies in the northern hemisphere may see their busy summer months affected if the virus spreads. The effect on balance sheets may be visible with indebted companies and/or those with more exposure to affected areas disproportionately affected. The wildcard here is whether coronavirus transmits as easily in warmer weather as it does in the cooler winter months. In this case there may be a difference, generally speaking, between the global north and south. Exceptions to watch could be cooler southern places such as New Zealand, Argentina and Chile. Shortages, as mentioned above in Taiwan, potentially should be short term, owing to global overcapacity of cement production, as end users find supplies from elsewhere.

The cement industry is also likely to encounter disruption to its supply chains. Major construction projects in South Asia are already reporting delays as Chinese workers have failed to return following quarantine restrictions after the Chinese New Year celebrations. As other countries suffer uncontrolled outbreaks then similar travel restrictions may follow. Global Cement has yet to see any examples of materials in the cement industry supply chain being affected. On the production side, raw mineral supply tends to be local but fuels, like coal, often travel further. Fuel markets may prove erratic as larger consumers cut back and suppliers like the Organisation of the Petroleum Exporting Countries (OPEC) react by restricting production.

On the maintenance side cement plants need a wide array of parts such as refractories, motors, lubricants, gears, wear parts for mills, ball bearings and so forth. Some of these may have more complicated supply chain routes than they used to have 30 years ago. On the supplier side any new or upgrade plant project is vulnerable if necessary parts are delayed by a production halt, logistics delayed and/or staff are prevented from visiting work sites. Chinese suppliers’ reliance on using their own workers, for example, might well be a hindrance here until (or if) international quarantine rules are normalised. Other suppliers’ weak points in their supply chains may become exposed in turn. This would benefit suppliers with sufficiently robust chains.

Chinese reductions in NO₂ emissions in relation to the coronavirus industrial shutdown have been noted in the press. A wider global effect could well be seen too. This could potentially pose problems to CO₂ emissions trading schemes around the world as CO₂ prices fall and carbon credits abound. This might also have deleterious effects on carbon capture and storage (CCS) development if it becomes redundant due to low CO₂ pricing. In the longer-term this might undesirable, as by the time the CO₂ prices pick up again we will be that much nearer to the 2050 sustainability deadlines.

COVID-19 is a new pandemic in all but name with major secondary outbreaks in South Korea, Iran and Italy growing fast and cases being reported in many other countries. The bad news though is that individual countries and international bodies have to decide how to balance the economic damage disease control will cause, versus the effects of letting the disease run unchecked. Yet as more information emerges on how to tackle coronavirus, the good news is that most people will experience flu-like symptoms and nothing more. Chinese action shows that it can be controlled through public health measures while a vaccine is being developed.

Until then, frequent handwashing is a ‘given’ and many people and organisations are running risk calculations on aspects of what they do. It may seem flippant but even basic human interaction such as the handshake needs to be reconsidered for the time being.

France: Following a successful trial that began in December 2019, LafargeHolcim has inaugurated a FastCarb CO₂ absorption accelerator into concrete production at its Val d'Azergues cement and concrete plant (integrated capacity 0.4Mt/yr) in Lozanne. The technology involves the capture of CO₂ from the plant’s cement kiln for reinjection into concrete produced with recycled aggregates. François Petry, LafargeHolcim France managing director, said the installation ‘fits perfectly into our Lafarge 360 approach for more responsible construction.’ The five-pillar approach consists of alternative fuel substitution and development, power consumption reduction, formulation of new cements, cooperation with Airium insulation solutions and assistance with low-carbon building design.

If you needed a sign that the cement industry has become serious about carbon capture it was the presence of two organisations offering CO₂ transport and storage capacity in northern Europe at last week’s Innovation in Industrial Carbon Capture Conference 2020 (IICCC). Both Norway’s Northern Lights and the Rotterdam CCUS (Project Porthos) were busy at their stands during the event’s exhibition. Meanwhile, Cembureau, the European Cement Association, said that it will work on finding other potential storage sites for CO₂ and on identifying existing gas pipelines that could be converted. The industry is planning what to do about CO₂ transport and storage.

As with the previous IICCC event in 2018 the heart of the programme was the Low Emissions Intensity Lime And Cement (LEILAC) project. Since then Calix’s 60m tall pilot Direct Separation Calciner unit has been built at the HeidelbergCement cement plant in Lixhe and has been tested since mid-2019. Early results look promising, with CO₂ separation occurring, calcined material produced and the tube structure and mechanical expansion holding up. Problems with thermocouples failing, blockages and recarbonation at the base of the tube have been encountered but these are being tackled in the de-bottlenecking phase. Testing will continue well into 2020 and plans for the next demonstration project at another cement plant in Europe are already moving ahead. LEILAC 2 will see industry partners Cimpor, Lhoist, Port of Rotterdam and IKN join Calix, HeidelbergCement and other research partners to work together on a larger 0.1Mt/yr CO₂ separation pilot scheduled for completion in 2025.

Alongside this HeidelbergCement presented a convincing vision of a carbon neutral future for the cement industry at the IICCC 2020. It may not be what actually happens but the building materials producer has a clear plan across the lifecycle chain of cement. It is researching and testing a variety of methods to capture CO₂ process emissions, is looking at supply chains and storage sites for the CO₂ and is working on recycling concrete as aggregates and cementations material via recarbonation. In terms of carbon capture technology, an amine-based industrial scale CCS unit looks likely to be built at Norcem’s Brevik plant in the early 2020s. HeidelbergCement’s other joint-research projects – direct separation and oxyfuel – are further behind, at the pilot and pre-pilot stages respectively. Each technology looks set to offer progressively better and cheaper CO₂ capture as they come on line.

Or put another way, cement companies in Europe could build industrial scale amine-based carbon (CC) capture plants now. Yet the game appears to be to wait until the cost of CCS falls through new technology versus the rising emissions trading scheme (ETS) price of CO₂. CC is expected to become economically feasible in a decade’s time, sometime in the 2030s. At which point there might be an upgrade boom as plants are retrofitted with CC units or new production lines are commissioned. Other ways of reducing the cement industry’s CO₂ emissions, of course, are being explored by other companies such as further reducing the clinker factor through the use of calcined clays (LC3 and others), solar reactor or electric-powered kilns and more.

The usual problem of how the construction industry can cope with a higher cost of cement was acknowledged at IICCC 2020 but it is largely being worked around. Higher priced cement poses competitive issues for specifiers and construction companies but it is widely expected to result in price rises below 5% for most residential end users. In the short-term government policy such as requiring low carbon cement in state building projects could stimulate the market. The start of this process can be seen already with the use of slag cements in various infrastructure projects.

Hans Bergman, Head Unit ETS Policy Development at the Directorate-General for Climate Action (DG Clima) partly addressed the cost issue by talking about the EU Green Deal. The EU wants to meet its new targets but it also wants to let gross domestic product (GDP) rise whilst greenhouse emissions fall. The EU ETS is its principle vehicle for this but the commission is wary of changes, such as making modifications linked to CCS, in case it undermines the system. Discussions are ongoing as the work on the Green Deal continues.

IICCC was a wider forum beyond just what LEILAC is up to. To this extent the CC projects involve multiple partners, including those from other cement companies like Cemex and Tarmac (CRH) in LEILAC and Dyckerhoff (Buzzi Unicem), Schwenk Zement and Vicat in the oxyfuel project. The decarbonisation fair included representatives from Vicat’s FastCarb project and Polimi’s Cleanker. Speakers from the European Climate Foundation, Acatech, INEA, TCM, SINTEF and Lhoist were also present.

During one speaker discussion Calix was described as the 'Tesla' of industrial CC by one speaker, who said that, “…there is a genuine competitive opportunity for those bold enough to grasp it.” Calix’s managing director Phil Hodgson enjoyed the accolade but the point was that leading innovation or setting the agenda offers advantages. In the case of industrial CC for the cement industry, change feels a step closer.

Dalmia Cement threw down the gauntlet this week with the announcement of a large-scale carbon capture unit (CCU) at one of its plants in Tamil Nadu, India. An agreement has been signed with UK-based Carbon Clean Solutions Limited (CCSL) to use its technology in building a 0.5Mt/yr CCU. The partnership will explore how CO₂ from the plant can be used, including direct sales to other industries and using the CO₂ as a precursor in manufacturing chemicals. No exact completion date or budget has been disclosed.

The move is a serious declaration of intent from the Indian cement producer towards its aim of becoming carbon neutral by 2040. Dalmia has been pushing its sustainability ‘journey’ for several years now hitting targets such as reaching 6Mt of alternative raw materials usage in its 2018 financial year and reaching a clinker factor of 63% at the same time. In an article in the November 2018 issue of Global Cement Magazine it said it had achieved CO₂ emissions of 526kg/t from its cement production compared to 578kg/t from other Indian members of the Cement Sustainability Initiative (CSI). In its eastern operations it had gone further to reach 400kg/t.

Using CCU is the next step to this progression but Dalmia’s approach is not without its caveats. Firstly, despite the size of the proposed project it is still being described as a ‘large-scale demonstration.’ Secondly, the destination of all that captured CO₂, as mentioned above, is still being considered. CCSL uses a post-combustion capture method that captures flue gas CO₂ and then combines the use of a proprietary solvent with a heat integration step. Where the capture CO₂ goes is vital because if it can’t be sold or utilised in some other way then it needs to be stored, putting up the price. Technology provider CCSL reckons that its CDRMax process has a CO₂ capture price tag of US$40/t but it is unclear whether this includes utilisation sales of CO₂ or not.

The process is along similar lines to the Skyonic SkyMine (see Global Cement Magazine, May 2015) CCU that was completed in 2015 at the Capitol Cement plant in San Antonio, Texas in the US. However, that post-combustion capture project was aiming for 75,000t/yr of CO₂. Dalmia and CCSL’s attempt is six times greater.

Meanwhile, Cembureau, the European cement association, joined a group of industrial organisations in lobbying the European Union (EU) on the Horizon Europe programme. It wants the budget to be raised to at least Euro120m with at least 60% to be dedicated to the ‘Global Challenges and European Industrial Competitiveness’ pillar. This is relevant in a discussion on industrial CO₂ emissions reduction because the scheme has been supporting various European cement industry projects, including HeidelbergCement’s work with the Low Emissions Intensity Lime And Cement (LEILAC) consortium and Calix at its Lixhe plant in Belgium and its pilots in Norway. As these projects and others reach industrial scale testing they need this money.

These recent developments provide hope for the future of the cement industry. Producers and their associations are engaging with the climate change agenda and taking action. Legislators and governments need to work with the cement sector to speed up this process and ensure that the industry is able to cut its CO₂ emissions while continuing to manufacture the materials necessary to build things. Projects like this latest from Dalmia Cement are overdue, but are very encouraging.

Belgium: Australia’s Calix says the Low Emissions Intensity Lime And Cement (LEILAC) consortium has successfully demonstrated CO₂ separation with more than 95% purity at its pilot unit at HeidelbergCement’s cement plant in Lixhe. Technology provider Calix said that preliminary test runs have been completed on the pilot. The technology concept has been shown to work on both lime and cement meal, with calcination near to target levels and high purity CO₂ successfully separated at the top of the reactor although not yet at full design capacity.

It added that it was still working on fixing commissioning issues. Testing will run until the end of 2020 to assess the risk of potential longer-term issues such as tube health and process robustness. In parallel, planning has commenced on the next scale-up of the technology, including conceptual design and engaging funding consortia.

Canada: Lafarge Canada has launched the first phase of its CO₂MENT project. The objective is to build a full-cycle solution to capture and reuse CO₂ from a cement plant. The project is a partnership between Lafarge Canada, Inventys and Total.

“LafargeHolcim is committed to reducing CO₂ emissions and we are excited to join forces with Inventys and Total through Project CO₂MENT. We hope to discover ways to capture emissions from our production processes and reuse them in our products, advancing a circular economy even further than today. The recent launch of the new lower carbon fuel (LCF) system at our Richmond plant aims to make the facility the most carbon efficient cement plant in Canada,” said René Thibault, Region Head North America for LafargeHolcim.

Over the next four years, Project CO₂MENT will demonstrate and evaluate Inventys’ CO₂ Capture System and a selection of LafargeHolcim’s carbon utilization technologies at its Richmond cement plant in British Columbia. The project has three phases and is expected to be fully operational by the end of 2020. Subject to the pilot’s success, the vision is to scale up the project and explore how the facility can be replicated across other LafargeHolcim plants.

During the first phase the partners will work on purifying the cement flue gas in preparation for CO₂ capture. The second phase will focus on the separation of CO₂ from flue gas using a customised for cement version of Inventys’ carbon capture technology at pilot scale. As part of the final phase, the captured CO₂ will be prepared for reuse and support the economical assessment and demonstration of CO₂ conversion technologies onsite, such as CO₂ injected concrete and fly ash.

There were two main takeaways from the Global Future Cement Conference that took place in Brussels last week. Firstly, there are not any obvious alternatives to using cement and concrete. Secondly, serious at-scale commercial investment on capturing CO₂ process emissions from clinker production is still waiting for the right economic conditions.

Although the conference was heavily focused on Europe, the graph above explains why the cement and concrete industries are sitting pretty right now in the face of mounting environmental activism. The sector may be responsible for 5 - 10% of annual CO₂ emissions but, put bluntly, there is simply no alternative. As Karen Scrivner from the Ecole Polytechnique Fédérale de Lausanne (EPFL) explained during her presentation, concrete uses some of the most abundant minerals present on earth, notably silicon and calcium. Alternative chemistries are simply not backed up by available materials. The cement and concrete associations have strongly promoted the unique position by focusing on the whole lifecycle of building materials.

The energy and emissions research needs to be scrutinised much more closely but, if it’s correct, there is no way to maintain modern standards of living without concrete. And, judging from the response by the French public to a badly handled meagre carbon tax on diesel by the so-called Yellow Vest movement, whacking up the price of housing or infrastructure might go down badly, especially in developing countries.

Two immediate ‘outs’ presents themselves. Cement doesn't necessarily have to be made from clinker as Robert McCaffrey’s presentation reinforced (also given at the IEEE/IAS-PCA Cement Conference this year). Future research may find alternatives to clinker and wipe out the cement business in the process. Also, the graph above is based on per kilogramme amounts of each building material. It doesn’t indicate how much of each material is required to build things. Even if clinker-based building materials are irreplaceable, there is no reason why their market share might not decrease. This could have large consequences in a market already burdened by over-capacity.

Solid research into carbon capture technology is proceeding apace, from the LEILAC project at HeidelbergCement’s Lixhe plant, to oxyfuel kiln development and other methods, as Jan Theulen from HeidelbergCement demonstrated in his presentation. Off-the-shelf technologies from other industries also exist ready to be used. Today, for example, Inventys has announced plans to test its own CO₂ capture technology with Lafarge Canada. Yet there are no commercial-scale installations in Europe. most likely due to the price burden it would place on the end product.

With the European Union (EU) Emissions Trading Scheme (ETS) entering its fourth phase and the carbon price holding above Euro20/t the question is: when will the serious investment begin in Europe? Notably, more than a few major European cement equipment manufacturers attended the Global Future Cement Conference, yet none are offering mature products to capture CO₂ emissions. Most or all have projects up their sleeves ready to be developed and sold but orders aren’t being received. The carbon price in Europe is the problem here. If it's too low then nothing happens outside of government subsidy. Too high and cement plants start being shut down because they become too expensive to run. To be fair to the cement sector other carbon emission mitigation strategies are being employed from alternative fuels usage to lowering the clinker factor and other methods but the endgame is based on reducing process emissions.

The challenge for the cement and concrete industry is to show legislators that their materials are essential and irreplaceable. They are doing this. The legislators then need to concoct ways of encouraging mass scale rollout of carbon emissions abatement technology without destroying the cement industry. This is far from certain right now. If nothing else it’s in governments’ interest to get this right because, as the Yellow Vest protests show, if they get it wrong their voters become angry. All of this is happening against the clock as CCU/S is required to get the cement industry past the 2050 2°C maximum warming target set by the Paris Agreement. In the meantime the cement industry is essentially in a holding position on the more far-reaching aspects of CO₂ emissions mitigation. Its products are likely irreplaceable but its carbon capture technology has to be encouraged by governments. This means that, for most cement producers, waiting to see what happens next is the way forward.

The 3rd Future Cement Conference and Exhibition is scheduled to take place in Vienna, Austria in 2021
