Air Liquide and Lhoist working towards building carbon capture unit at Réty lime plant

11 May 2022

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 lime producers announce price rises

06 April 2022

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.

LEILAC-1 study concludes – and puts a price tag on carbon capture

13 October 2021

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.

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.

Lhoist to raise price of lime products

30 September 2021

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.”

Leilac-2 CCS project to begin in April 2020

30 March 2020

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.

Innovation in Industrial Carbon Capture Conference 2020

29 January 2020

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.
