Italy: Utilities provider Snam says that it has begun selecting partners for its upcoming Ravenna carbon capture and storage (CCS) transport network. The network will connect hard-to-abate industrial facilities in Ravenna with 500Mt of CO₂ storage space in the Mediterranean Sea. The total cost of infrastructure for the project is Euro350m.

CEO Stefano Venier said "The cement industry will be a central partner in this project. A partnership with Heidelberg will be announced in a few days."

US: Portland Cement Association (PCA) chief economist and senior vice president of market intelligence Ed Sullivan forecast a recovery of the US economy in the second half of 2024 at the World of Concrete conference in Las Vegas, Nevada. However, Sullivan told attendees that the economy will ‘gradually weaken’ in the first half of the year. The anticipated weakening is compounded by the end of Covid-19 relief programmes, delayed monetary policy effects and credit tightening. Supporting growth throughout the year are some of the US$550bn infrastructure investments under the Infrastructure Investment and Jobs Act. The US government says that 40,000 new projects under the act are either in progress or completed.

Ed Sullivan said "In terms of the construction outlook, there will be a battle between interest sensitive construction sectors and less interest sensitive construction activity such as infrastructure spending and the construction of large manufacturing plants associated with the CHIPS and Science Act."

Azerbaijan: Cement production in Azerbaijan increased by 4.6% year-on-year to 3.73Mt in 2023, data from the State Statistics Committee has shown. Clinker production rose even more sharply, by 37%, to 3.87Mt. BNI IntelliNews has reported growth of 32% year-on-year in the overall value of building materials in 2023, to US$694m.

Brazil: Votorantim Cimentos plans to invest US$1bn in expanding its Brazilian operations in the period up to the end of 2028. US$304m-worth of the investments are already underway at the start of 2024. Reuters has reported that the investments include cement plant projects to raise Votorantim Cimentos’ Brazilian cement production capacity by 8.8% to 37Mt/yr. These include a US$162m investment in a 20% capacity expansion to its Votorantim cement plant and a US$60.8m, 1Mt/yr expansion to its Salto de Pirapora plant. Further aims are to ensure structural competitiveness, raise energy efficiency and digitise operations, including applying artificial intelligence (AI) to freight. The producer expects its earnings before interest, taxation, depreciation, and amortization (EBITDA) to eventually rise by US$263/yr between 2023 and 2028 as a result.

US: Eagle Materials recorded sales of US$1.78bn in the first nine months of the 2024 financial year. This corresponds to a rise of 6.2% year-on-year from the corresponding period of the 2023 financial year. The producer’s heavy materials sales rose by 18% to US$889m, and its cement sales volumes rose by 2% to 6Mt. As a result, Eagle Materials raised its net earnings by 11% to US$401m.

China: China Shanshui Cement expects its full-year loss to exceed US$120m in 2024. Reuters has reported that the producer attributes the anticipated decline to a ‘substantial’ drop in cement sales prices.

India: Dalmia Bharat's consolidated sales were US$433m in the third quarter of the 2024 financial year (1 October – 31 December 2023), up by 7.3% year-on-year. This was in part due to an 8.1% rise in the company’s cement sales volumes, amid a nationwide infrastructure spending drive. Its net profit rose by 22% year-on-year to US$32m. The producer partly attributed this to a market correction in the price of raw materials. Premium products accounted for 21% of Dalmia Bharat’s cement sales during the quarter.

Managing director and CEO Puneet Dalmia said “While we believe that margins may improve further from here on, our focus for the next 12 – 15 months will remain on improving our capacity utilisation and delivering industry-leading volume growth.”

UK: Aggregate Industries has engaged energy engineering firm Petrofac to investigate a carbon capture project at its Cauldon cement plant. Petrofac is currently conducting early engineering assessments to identify CO₂ capture opportunities at the plant in Staffordshire. This includes technology selection for any future project. Upon commissioning, a carbon capture system will support the storage of up to 600,000t/yr of CO₂ from the Cauldon cement plant under the Irish Sea as part of the cross-industry Peak Cluster carbon capture and storage (CCS) project.

Aggregate Industries decarbonisation manager Luke Olly said "Aggregate Industries is excited to be launching this carbon capture study, as we are aiming to fully decarbonise our cement plant by 2030. This technology is an important part of our strategy."

Petrofac head of business development energy transition projects, Alex Haynes, said "We’re looking forward to working with Aggregate Industries UK in finding a way to reduce the carbon footprint of its cement products."

India: Sagar Cements recorded sales of US$80.5m in the third quarter of the 2024 financial year, up by 16% year-on-year from US$69.3m during the corresponding quarter of the previous financial year. Cement sales volumes rose by 14% year-on-year. The Hindu BusinessLine News has reported that the growth allowed Sagar Cements to reduce its net losses by 57%, to US$1.22m.

Managing director Sreekanth Reddy said “Favourable prices prevailed in our key markets. As far as EBITDA and margins are concerned, we observed a significant enhancement on a per-tonne basis, consistent with our earlier projections.” Reddy added “We anticipate this positive trend to persist in the future, supported in part by higher utilisation levels of recently-acquired units and strategic initiatives aimed at promoting the use of green power, alternative fuels and the deployment of electric trucks and wheel loaders.”

It has been a busy week for carbon capture in the cement sector with Global Cement covering five stories. However, increasingly, the topic has become a regular feature in the press as the industry bends to the demands of the carbon agenda. This week’s selection is notable because three of the stories cover North America.

Holcim US announced that it is working with Ohio State University and GTI Energy to design, build and test engineering-scale membrane carbon capture technology at the Holly Hill cement plant in South Carolina. The information builds on an earlier release from the US Department of Energy’s (DOE) Office of Fossil Energy and Carbon Management (FECM) in late December 2023 about the project. It has a total budget of US$9m, with US$7m supplied by the DOE. It plans to build a 3t/day CO₂ capture unit that uses a method intended to retain 95 - 99% of CO₂ from cement kiln gas with a purity exceeding 95%. The new information at this stage is that GTI Energy is involved. Specifically, it will support the development of the pilot skid for site deployment.

The other two stories from North America are worth noting because they both concern commercial equipment or technology suppliers joining up to work together. First, 10 companies - Biomason, Blue Planet Systems, Brimstone, CarbonBuilt, Chement, Fortera, Minus Materials, Queens Carbon, Sublime Systems, and Terra CO₂ - announced they were launching the Decarbonized Cement and Concrete Alliance (DC2). The group’s principal aim is to lobby the US government toward using new low-carbon cement and concrete products in public infrastructure. It also intends to look at advocacy and public sector engagement including expanded tax credits, development of standards for novel cements, consistent ecolabeling and accounting, and customer demand support. DC2 was formally launched in January 2024 but it follows previous work by the companies in the area. The other related story was a memorandum of understanding that Aker Carbon Capture and MAN Energy Solutions have also signed this week to jointly pursue opportunities related to carbon capture, utilisation and storage (CCUS) and CO₂ compression in the North American market. These two companies have worked on the full-scale CCUS unit at Norcem’s Brevik cement plant, which is due to be commissioned later in 2024. They are likely intending to capitalise on the publicity that is likely to be generated once it officially starts up.

Back in North America the DC2 Alliance noted in its press release the DOE’s release of its Pathways to Commercial Liftoff: Low-Carbon Cement report in September 2023. Although it is similar to many other varied sector roadmaps, including the Portland Cement Association’s Road to Net Zero that was released in 2021, this document is well worth reading due to its details and local market context. The headline figure, for example, is that following a set of pathways to fully decarbonise the US cement industry would cost US$60 - 120bn by 2050. Doing so would involve reducing the clinker factor, improving energy efficiency, increased use of alternative fuels, using CCUS, using alternative feedstocks and adopting alternatives to traditional cement production methods.

One other interesting tidbit to consider from the report is an analysis of the age of the US cement sector’s kilns versus their production capacity as shown in Graph 1 above. The largest 10 kilns in the country account for 22% of the country’s total capacity and these were all built after 2000. Then, the next 44% of the national capacity comes from 38 kilns out of a total of 120 kilns at 98 cement plants. The report itself does not make this assertion but the implication is that retrofitting CCUS units at one third of the country’s clinker lines would capture the CO2 being emitted from two-thirds of the sector’s production capacity. This is not to say that this could actually work technically, logistically or economically. Yet seeing the scale of the challenge presented in this way is fascinating and one starts to have thoughts about how a retrofit roll-out of CCUS units might actually be approached.

Whether the cement sector adopts CCUS at scale remains to be seen but demonstration projects are definitely coming in both Europe and North America. The DOE report from September 2023 suggests that decarbonisation will cost a lot of money. No surprises there and, as ever, there is rather less detail on who will actually pay for this. One thing that might help here, that the DOE report mentions frequently, is the 45Q carbon capture tax credit scheme, which was introduced by the Trump administration in 2020. Regardless of the potential bill for consumers of cement though, the suppliers are clearly taking note of the investment potential as evidenced by all the non-cement plant CCUS news stories this week.

The 1st Global CemCCUS Conference will take place 13 - 15 May 2024 in Norway and it will include a plant tour of the Norcem Brevik cement plant and CCS project
