US: The Board of County Commissioners of Boulder, Colorado, has denied Cemex USA’s application for a 15-year extension to its Dowe Flats quarry mining licence, following its expiry on 30 September 2022. Commissioner Claire Levy cited dust, traffic, noise and disturbances to wildlife as reasons behind the decision.

Cemex USA’s nearby Lyons cement plant has previously relied on the quarry for the supply of 760,000t/yr of limestone.

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.

Argos 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.

UK: 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.

Dominican Republic: The President of the Dominican Republic, Luis Abinader, has inaugurated the kiln of a restarted production line at the San Pedro de Macorís cement plant. The US$34m upgrade project was started in 2021. The line has a clinker production capacity of 0.5Mt/yr and it has been restarted to support the local market. The announcement follows the start of a project to use hydrogen at the unit that began in late August 2022. The plant also plans to increase its use of alternative fuels, move to using more CO₂-free materials and increase its use of additives over the next five years.

Philippines: Cemex Philippines says that it was the sole supplier of cement for the construction of the Cordova Link Expressway, the longest bridge in the country. It supplied nearly 70,000t of cement for the project. It connects Cebu City to the municipality of Cordova on Mactan Island and spans a total of 8.9km standing on twin tower pylons reaching 145m in height. The bridge opened to road traffic in 2022.

Finland: Coolbrook, the manufacturer of electrically-powered gas heating technologies, has announced the appointment of Mikko Jaatinen as its first chief financial officer (CFO).

US: The Boulder County Planning Commission has recommended that county commissioners should reject Cemex USA’s application to extend its licence to mine limestone at its Dowe Flats quarry until 2037. Local press has reported that Cemex USA previously agreed to shut down its Lyons cement plant at the expiry of its extended licence in 2037. The company says that it will be able to continue operating the plant without use of the mine.

Cemex USA executive vice president Trpimir Renic said "We do always try and consume the raw materials that are available to us at the existing site where we are currently operating. We think that operating that quarry for the next 15 years - supplying Lyons cement plant - is the most responsible resource management operation that we can undertake."

Mexico: Cemex has successfully closed its sale of its Costa Rica and El Salvador subsidiaries to Cementos Progreso for US$329m. Cemex plans to use the proceeds from the divestments to fund its bolt-on investment growth strategy, reduce its debt and for other general corporate purposes.

Jamaica: Mexico-based Cemex plans to expand production by up to 30% at its integrated Rockfort cement plant near Kingston. The first phase of the upgrade project will cost around US$40m and be completed during 2024. Cemex’s chief executive officer Fernando A Gonzalez made the announcement during a visit to the plant. Andrew Holness, the Prime Minister of Jamaica, also attended the event.

Gonzalez said “We are in the final stages of the engineering phase and in obtaining permits from the local authorities.” He added, “Very soon we will begin to procure the equipment needed for this initial phase of the project, designed to not only expand our capacity, but also allow us to optimise our heat consumption in the manufacturing process, and therefore, reduce the carbon footprint of our cement facility in Jamaica.”

The event also included the unveiling of a mural at the plant which commemorates the 60th anniversary of Jamaica’s independence. Titled ‘Reignited for Unity’, the mural measures around 15m tall by 50m wide. It was painted by Mexican artists Irving Cano and Freddie Herrera and Jamaican artists Anthony Smith, Yanque Yip and Jordan Harrison. The mural is part of a local government initiative to use art to promote different communities in Kingston.
