Belgium: Holcim and TotalEnergies have signed a memorandum of understanding (MOU) to work towards the full decarbonisation of the Obourg cement plant. Various energies and technologies will be assessed for the capture, utilisation and sequestration (CCUS) of around 1.3Mt/yr of CO₂ emitted by the unit. The project will include working towards building an oxyfuel switchable kiln as part of an upgrade project at the plant and the transportation and use of the captured CO₂ by TotalEnergies for a synthetic fuel producing scheme and/or deposit in geological storage in the North Sea.

TotalEnergies will also assess the development of renewable projects to power a new electrolyser, which would generate the green hydrogen needed to produce synthetic fuels. This new renewable energy production capacity would also power Holcim’s new oxyfuel kiln. Finally, the oxygen emitted by the electrolyser would be used to fuel the new kiln.

Bart Daneels, the chief executive officer of Holcim Belgium said “Cement industry decarbonisation is extremely challenging because of the process's inevitable CO₂ emissions, which put us firmly in the hard-to-abate sector. CCUS is vital for Obourg to become the first net carbon neutral clinker plant in northwest Europe. We are very happy to work with TotalEnergies to accelerate the development of these CCUS solutions for GO4ZERO. By joining the first movers, we want to set the standards for future clinker manufacturing plants.”

US: Heliogen is among recipients of a total US$24m in US Department of Energy funding for solar thermal power projects. The department granted it US$4.1m-worth of funding for a project in which it will calcine limestone at 950°C using the heat of the Sun. Heliogen hopes to apply the methods it is developing to prevent the direct emissions of cement production.

India: JSW Cement has taken a loan of US$48.9m with which to finance its planned 47% capacity growth to 25Mt/yr from 17Mt/yr. MUFG Bank India provided the loan subject to sustainability-linked criteria. Press Trust of India News has reported that the producer’s subsidiary Shiva Cement is in the process of establishing a US$183m 1.36Mt/yr clinker plant and 1Mt/yr grinding plant in Odisha’s Sundergarh District.

India: Research by the Indian Institute of Technology – Madras (IIT Madras) has concluded that limestone calcined clay cement (LC3) production emits 40% less CO₂ than ordinary Portland cement (OPC) production, and is 20% less energy intensive. United News of India has reported that the Switzerland-based Swiss Agency for Development and Cooperation supported the study.

US: Thailand-based Siam Cement Group (SCG) has invested in Rondo Energy, developer of the Heat Battery. The cement company aims to help its various business lines to decarbonise their operations through deployment of Rondo Energy’s technology. Rondo Energy said that the partnership will support and earlier expansion of its product’s footprint across Southeast Asia and worldwide.

Rondo Energy chief executive officer John O’Donnell said “Rondo is excited to be working with SCG. Rondo’s technology opens a new pathway for SCG to achieve their deep decarbonisation goals and simultaneously reduce their operating costs. SCG’s deep capabilities in execution and quality will enable Rondo to deliver reliable energy infrastructure rapidly and at scale. Together, Rondo and SCG have the global footprint to deliver deep decarbonisation projects, including heat as a service projects in Southeast Asia and worldwide.”

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.”

India: Adani Group plans to invest US$100bn in capital expenditure across all of its operations between 2022 and 2032. Mint News has reported that the conglomerate will establish 45GW-worth of new hybrid renewable power plants under the plans. It will also build three new green hydrogen plants, with a combined capacity of 3Mt/yr. It plans to support the latter move with an investment of US$70bn in the establishment of an integrated hydrogen-based value chain.

Spain: Sustainability Observatory's Decarbonisation 2022 report has named FCC, Cemex and Holcim on a list of Spain's top 10 CO₂ emitters. Construction conglomerate FCC, parent company of Cementos Portland Valderrivas, was the seventh largest contributor the country's CO₂ emissions during the year. Mexico-based Cemex placed joint eighth with energy provider Iberdrola at 2.4Mt-worth of CO₂ emissions in 2021, followed by Switzerland-based Holcim with 2Mt.

Spanish CO₂ emissions grew by 5.1% year-on-year in 2021, and by 3% across industries subject to emissions credit trading, which include the cement sector. Together, the top 10 emitters accounted for 57% of these industries' emissions, and 19% of total national emissions.

Greece: Titan Cement Group says that its H2CEM green hydrogen projection has received inclusion under the EU Important Project of Common European Interest (IPCEI) Hy2Use. Hy2Use consolidates funding for hydrogen electrolysis, transport and storage development projects across Europe. Titan Cement Group’s H2CEM project consists of Euro60m-worth of new green hydrogen production installations at its Drepano, Efkarpia and Kamari cement plants. The installations will produce hydrogen through electrolysis using renewable energy sources. The producer says that use of the hydrogen as cement fuel will reduce the plants’ CO2 emissions per tonne of cement by 8%, corresponding to 160,000t/yr of emissions. H2CEM is Hy2Use’s only cement plant project.

Titan Cement Group aims to achieve carbon neutrality by 2050.

UK: 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.”
