Wright Engineering upgrades Lhoist's Whitwell lime plant
13 October 2022UK: Wright Engineering has installed new inlet sealings on a kiln at Lhoist's Whitwell lime plant in Derbyshire. The new configuration increases the distance between the kiln's leaf segments and inlet to 400mm. The supplier says that the increased distance from the flow of incoming material will alleviate spillage issues in the kiln.
Seratech's carbon-neutral cement wins Obel Award 2022
10 October 2022UK: Denmark-based architecture fund Henrik Frode Obel Foundation has named Seratech as winner of its Obel Award 2022. The award recognises architectural contributions to global development. Seratech has developed an olivine-based composite cement produced using CO2 from flue emissions, which can sequester double the CO2 of ordinary Portland cement (OPC). When used as 40% of a blend with OPC, it is able to completely offset the emissions of concrete production.
Team member Barnaby Shanks said "The beauty of the idea is that you can just use it as normal concrete. There are other carbon-neutral materials, but they can be limiting because they can only be precast, cured in a lab in special conditions and shipped elsewhere. We want people to retain the freedom to use concrete the way that they are used to. We don’t want to limit people in any way because we’ll just lessen the amount of impact we can have."
UK: Breedon Group, together with Australia-based First Graphene, Morgan Sindall Construction & Infrastructure and the University of Manchester, is developing a new reduced-CO2 graphene-enhanced cement. The consortium is currently formulating the cement using varying doses of First Graphene’s PureGRAPH graphene-enhanced grinding aid. The project received a research grant from the UK government earlier in 2022. First Graphene says that the study involves one of the largest commercial trials of its kind to date globally. It is simultaneously collaborating on another similar trial with a Europe-based speciality chemicals producer.
On 29 September 2022, First Graphene launched its latest range of graphene-enhanced cement grinding aids and concrete additives. These join recent launches PureGRAPH AM, an admixture developed in collaboration with South Africa-based Nanoproof/Glade Chemicals, and HexMortar, a dry mortar mix which will be distributed by New Zealand-based GtM Action.
First Graphene says that its cement and concrete segment’s order pipeline totals US$113m in value. Managing director and chief executive officer Michael Bell said “It is pleasing to see our efforts, and those of our collaboration partners, coming to fruition at a commercial scale. One of the primary drivers for the adoption of graphene solutions in this segment is the reduction of CO2 emissions. We’re seeing considerable benefits both in the immediate reductions that can be achieved through the use of graphene-enhanced grinding aids, as well as the potential reductions in concrete usage because of the enhanced physical properties these products provide.” Bell concluded “Working with industry-focused partners such as Nanoproof/Glade Chemicals, GtM Action, Breedon Cement and Fosroc opens the way to an estimated addressable market of more than 12,000t of PureGRAPH across the medium to long term.”
Innovative Ash Solutions launches supplementary cementitious material made from incinerator waste
27 September 2022UK: Innovative Ash Solutions, a joint venture of Levenseat and Organic Innovative Solutions, has launched a new air pollution control residue (APCR)-based supplementary cementitious material (SCM). The supplier produces the material at its Lanarkshire treatment facility using APCR local from municipal solid waste (MSW) and wood biomass incinerators. Innovative Ash Solutions has received planning permission for a 54,000t/yr industrial-scale APCR-based SCM plant, and plans to establish a total of three plants in the UK, one of which will reach a capacity of 500,000t/yr. It has also signed an exclusive licensing agreement with an Australia-based importer for the material.
The SCM is designed to replace pulverised fly ash (PFA), of which the UK imported 325,000t in 2019, more than four times its 2012 import volumes of 76,000t.
Innovative Ash Solutions director Robert Gren said “We are excited to bring this new product to market. Innovative Ash Solutions is the first and, so far, the only company in the UK to have achieved ‘End of Waste’ accreditation for a PFA replacement for this type of use. Our research shows there is potential to produce more than 500,000t/yr of PFA replacement from UK APCRs every year, which would reduce the need for importing materials and support the decarbonisation of cement and concrete products.”
Clean Energy Ministerial CCUS and the GCCA to collaborate to scale up cement carbon capture deployment
26 September 2022UK: Clean Energy Ministerial CCUS (CEM CCUS) and the Global Cement and Concrete Association (GCCA) have announced a new partnership aimed at scaling up the deployment of carbon capture technologies in global cement and concrete production over the 10-year period up to 2033. The partners will explore incentives, policy frameworks and finance solutions that can best facilitate industrial-scale CCUS projects. Additionally, they will seek to ensure the long-term development of CCUS via technological developments.
CEM CCUS Norway initiative co-lead Henriette Nesheim said “This is a great opportunity to work together with a vitally important industry. In Norway we are already building our first cement CCS project in Brevik, and we look forward to sharing the experience with others.”
Update on hydrogen injection in cement plants
14 September 2022Argos Honduras revealed this week that it has been testing the injection of hydrogen into the kiln of its integrated Piedras Azules cement plant. It has completed a pilot with Portugal-based company UTIS. As part of the process it has been trialling, it has split water by electrolysis and then injected the hydrogen and oxygen directly into the kiln via the main burner. The pilot has reportedly increased clinker production and reduced petcoke consumption at the plant.
Argos is far from alone in using hydrogen in this way. At the end of August 2022 Cemex said that it was also starting to use hydrogen at its San Pedro de Macorís cement plant in the Dominican Republic. CRH UK-subsidiary Tarmac completed a trial in July 2022 using hydrogen as an alternative to natural gas at its Tunstead lime plant. HeidelbergCement UK-subsidiary Hanson also ran a successful trial using hydrogen as part of the fuel mix at its Ribblesdale cement plant in 2021. The government-funded trial used a combination of hydrogen (39%), meat and bone meal (12%) and glycerine (49%) to reach a 100% alternative fuels substitution rate. In 2021 Hanson reported that fuel switching to hydrogen could help it reduce its 2050 CO2 emissions by about 3%, or by -35kg CO2/t of cement product.
Cemex appears to be a leader in using hydrogen in this way. The Mexico-based company started injecting hydrogen in 2019 and retrofitted all of its European cement plants with the technology to do so in 2020. It then said it wanted to roll this out to the rest of its operations. The project in the Dominican Republic is an example of this. In February 2022 it announced an investment in HiiROC, a UK-based company that has developed a method using thermal plasma electrolysis to convert biomethane, flare gas, or natural gas into hydrogen. The stated aim of this investment was to increase Cemex's hydrogen injection capacity in its cement kilns and to increase its alternative fuel substitution rate. Back in 2020 Cemex said that it planned to use hydrogen injection to contribute 5% of its progress towards its 2030 CO2 emissions reduction target along with other measures such as increasing its thermal substitution rate and reducing its clinker factor.
As can be seen above there are a number of examples of hydrogen injection being used in cement plants in Europe and the Americas. However, there is very little actual data available publicly at this stage on how much hydrogen that the plants are actually using. For example, Cemex may have hydrogen injection equipment installed at all of its plants in Europe but it is unclear how many plants are actually using it. This is understandable though, given how commercially sensitive the fuel mix of a cement plant is and in Cemex’s case if it wishes to maintain a leader’s advantage in using a new technology.
It is interesting to see, in what has been released so far, the focus on doing deals with companies that supply electrolysis technology such as HiiROC and UTIS. A feasibility study ahead of the Hanson trial at Ribblesdale by the MPA, Cinar and the VDZ suggested that upgrading a kiln burner and adding all the necessary hydrogen storage and pipework could cost at least Euro400,000. However, this study also pointed out that the cost of hydrogen made a big difference to the cost of the CO2 saving from using it as an alternative fuel. Hence the focus on the technology partners. It will be interesting to see how many more hydrogen injection projects are announced in the coming months and years and, crucially, who is providing the technology to supply the hydrogen.
Hoffmann Green enters UK market
14 September 2022UK: Hoffmann Green Cement Technologies, a French company that manufactures and distributes low-CO2 clinker-free cement, has announced that it has signed its first partnership agreement in the UK with Cemblend, a supplier of customised cement powder mixes.
Hoffmann Green will supply Cemblend with its H-IONA, H-UKR and H-EVA clinker-free decarbonated cements for distribution to its customers in the UK and Ireland. This exclusive distribution agreement with volume commitments initially runs until the end of 2023 and is a first step towards the signature of a licensing agreement which could see Cemblend build and operate a production unit similar to Hoffmann Green's French production facilities.
Julien Blanchard and David Hoffmann, co-founders of Hoffmann Green Cement Technologies said, "We are pursuing the milestones of our international development with the signing of this structuring partnership in a strategic market in Europe. This first distribution contract in the UK is further proof of the attractiveness of our low-carbon solutions outside our borders. It is a first step in our cooperation process with Cemblend to build eco-responsible buildings across the Channel."
Cemex UK upgrades conveyor system at Swinderby aggregates quarry
12 September 2022UK: Cemex UK has invested in a new Canning Conveyor conveyor system at its Swinderby sand and gravel quarry in Lincolnshire. The 1.6km-long system will convey extracted materials to a new processing plant. The new plant will double the quarry’s aggregates production capacity. The system includes a 20t hopper feeder and a radial stockpile, also supplied by Canning Conveyor. The company producer says that the new equipment will cut 50% of the operations’ CO2 emissions by eliminating diesel-powered dumpster use and saving 300,000l/yr of fuel, in line with Cemex’s Future in Action sustainability programme. It will also reduce dust and noise at the quarry. The investment is due for completion in early 2023.
