Canada: McInnis Cement, Écotech Québec and the Gaspésie Cleantech Hub, in collaboration with the Québec Ministère de l’Économie et de l’Innovation, have launched a call for innovations to identify carbon capture and utilisation technologies for the Port-Daniel-Gascons, McInnis cement plant. This call for innovations will run until May 2020 and then selected organisations will be invited to explore future options.

“From the moment the company was founded, McInnis Cement has been exploring the option of replacing some of the hydrocarbons used as fuel for the plant with locally generated residual forest biomass so as to reduce its environmental emissions,” said Maryse Tremblay, Director of Communications and Corporate Social Responsibility at McInnis Cement. She added that a study to verify the feasibility of using this type of alternative fuels is underway and that this may be followed by a pilot project.

Écotech Québec is a non-profit organisation, funded by the provincial government, which represents Québec's ‘clean’ technology cluster. It supports businesses, researchers, investors and associations to help accelerate the development, financing and commercialisation of clean technologies. The Gaspésie Cleantech Hub is an economic development organisation created to help the region increase the economic benefits of establishing the McInnis cement plant.

US: Holcim US’s 1.9Mt/yr Portland cement plant in Colorado has become the latest site to host a large-scale cement plant carbon capture and storage (CCS) study. Holcim US, in partnership withCanada-based Svante, France-based Total and US-based Occidental subsidiary Oxy Low Carbon Ventures, will install a facility designed to capture 0.73Mt/yr of CO2, which Occidental will take for safe storage underground. The study will assess the financial viability and design requirements of such an installation on a permanent basis.

Hungary: Lafarge Cement Hungary has announced plans to upgrade clinker production at its 1.0Mt/yr Kiralyagyháza integrated plant with a Euro1.79m investment in chlorine bypass technology, which uses powdered limestone to remove chlorine and one tenth of the carbon dioxide (CO₂) from gases released in clinker production, which will then be used in clinker cooling. There will be a concomitant increase in the rate of alternative fuel (AF) substitution in the plant’s kilns, with an AF fuel store expansion in early 2020 set to raise AF usage to 80% from 60%.

Germany: Four of Europe’s leading cement producers have partnered to found and operate a 100% carbon capture and storage (CCS) plant at Schwenk Zement’s 1.0Mt/yr Mergelstetten plant in southern Germany. HeidelbergCement has announced that the catch4climate project will enter operation in 2020.

Belgium: A team of researchers from the University of Mons in Hainaut province has concluded a study in the use of amine-based solvents for carbon capture on between 20% and 60% CO₂ flue gas with funding from HeidelbergCement and the European Cement Research Academy. Lab tests and industrial-scale simulations showed that the solvents lowered regeneration energy, equivalent work and operating costs of carbon capture across the CO₂ concentration range of flue gases tested.

US: California-based Heliogen has developed concentrated solar-thermal plants (CSPs) with the ability to focus sunlight to generate temperatures over 1000°C by micro-adjusting mirrors using computer technology. It has now engaged Parsons Corporation to build arrays of its CSPs for installation in cement pre-calciners. Requiring 900°C heat, these represent the largest part of the industry’s CO₂ output. The technology will firstly reduce this by replacing fossil fuels with a clean heat source, which moreover entirely bypasses the electrical grid. Heliogen CEO Bill Gross says that the installations will make carbon capture and storage (CCS) of the remaining CO₂ emissions from the conversion of limestone to lime easier by removing other pollutants. Heliogen is now targeting 1500°C from its CSPs, which would enable them to supersede cement fuels in kilns.

Canada: HeidelbergCement’s Canadian subsidiary Lehigh Cement is trialling the cement industry’s first full carbon capture and storage (CCS) installation at its 1.4Mt/yr integrated Edmonton plant in Alberta in partnership with Canada’s International CCS Knowledge Centre. The installation will have a CO2 capture rate of between 90% and 95% and receive an investment of US$1.4m from the state government body Emissions Reduction Alberta (ERA). “We are part of HeidelbergCement’s vision of CO2-neutral concrete by 2050 and are committed to leading global change for CCS in our industry,” said Jeorg Nixdorf, Lehigh Hanson Canada regional president.

US: The construction company Cross River has partnered with Canada-based proprietary technology manufacturer Svante to deliver industrial carbon capture and storage (CCS) projects. BusinessWire has reported that Svante has already supplied its CCS pipelines to the 1Mt/yr CO₂ment concrete plant in British Colombia, a joint operation between Swiss LafargeHolcim and French Total which uses captured CO₂ to aerate its concrete.

Italy: Buzzi Unicem’s 1.3Mt/yr Vernasca plant in Piacenza will receive a Cleanker Project pilot system for carbon capture and storage (CCS). The installation is EU-funded as part of Horizon 2020, a seven-year research and innovation framework programme, and its success will be closely monitored for possible implementation at other cement plants in the EU and beyond.

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.
