US: Holcim US has unrolled its Holcim branding in the Atlanta Metropolitan Area in Georgia. The producer operates cement terminals at Cartersville, Duluth and Covington.

Southeast regional sales manager Lee Amick said "The rebrand signifies Holcim’s unwavering commitment to Atlanta construction and building companies, along with the greater community that has come to know us as a trusted partner. We're looking forward to building on our long-standing reputation for reliability, dependability, and assurance, now further rooted in sustainability and a profound dedication to environmental responsibility."

US: Holcim US has rolled out its own Holcim US brand across its operations in the Greater Chicago Area, which previously bore Lafarge branding. The operations include cement terminals and the South Chicago slag grinding plant. 400 people work for Holcim across the Greater Chicago Area.

Holcim US senior vice president and general manager, North Central Region, Randy Gaworski said “Right in the backyard of our company headquarters, we’re excited the Greater Chicago Area operations will now be recognised as Holcim. Customers will continue to experience the same quality products and services they expect from us today, but now have access to a larger network of services and innovation.”

US: Holcim US will invest US$100m in an expansion to raise its Ste. Genevieve cement plant’s capacity by 15% to 4.6Mt/yr. The expansion will involve the installation of a fifth vertical roller mill (VRM) for cement grinding and a new mineral component addition system, alongside a rail-loadout expansion. The producer says that the expanded plant will have lower net CO₂ emissions than before. Construction is set to commence in 2024.

Toufic Tabbara, head of Holcim’s North America region, said “With an emphasis on achieving the highest levels of environmental performance and operational efficiency, Ste. Genevieve has been the leader in US cement manufacturing since it was built in 2009. This investment will ensure we maintain that leadership in supporting the sustainable growth of our nation’s infrastructure and residential construction while accelerating net carbon reduction across the built environment.”

Taiwan Cement has just commissioned a 107MWh energy storage project at its Yingde plant in Guangdong province, China. Subsidiary NHOA Energy worked on the installation and has been promoting it this week. The battery storage works in conjunction with a 42MW waste heat recovery (WHR) unit, a 8MWp solar photovoltaic unit and a proprietary energy management system. It is expected to store about 46,000MWh/yr of electricity and save just under US$3m/yr in electricity costs.

NHOA Energy, formerly known as Engie EPS before Taiwan Cement bought a majority stake in it, claims it is one of the largest industrial microgrids in the world. We can’t verify this for sure, but it is definitely large. For comparison, the 750MW Vistra Moss Landing Energy Storage Facility in California often gets cited as the largest such facility in the world. This is run by a power company, as are many other large battery energy storage systems. In its annual report for 2022 Taiwan Cement said it was planning to using NHOA’s technology to build seven other large-scale energy storage projects at sites in Taiwan including its integrated Suao, Ho-Ping and Hualien cement plants.

The aim here appears to be supplying renewable electricity to the national grid in Taiwan. Taiwan Cement is diversifying away from cement production, with an aim to derive over 50% of its revenues from other activities besides cement by 2025. In 2022 cement and concrete represented 68% of its sales, while its electricity and energy division, including power supply and rechargeable lithium-ion batteries, represented 29%. The company is also not using its own batteries at the Yingde plant. Instead it is using lithium iron phosphate batteries supplied by Ningde Times. This is worth noting, as the cement producer’s batteries are used in vehicles.

Global Cement regularly reports news stories on cement plants that are building photovoltaic solar power arrays. However, so far at least, energy storage projects at scale have been rarer. One earlier example of an energy storage system loosely associated with a cement plant includes the now decommissioned Tehachapi Energy Storage Project that was situated next to the Tehachapi cement plant in California. That project tested using lithium ion batteries to improve grid performance and integrate intermittent generation from nearby wind farms. It is also worth noting that Sumitomo Osaka Cement’s sister company Sumitomo Electric is one of the world’s larger manufacturers of flow batteries, although no installation at a cement plant appears to have happened yet. In simple terms, flow batteries are an alternative to lithium ion batteries that don’t store as much energy but last longer.

More recently, Lucky Cement in Pakistan started commercial operation of a 34MW solar power plant with a 5.59MWh energy storage unit at its Pezu plant in Khyber Pakhtunkhwa in late 2022. Reon Energy provided the equipment including a lithium-ion based battery approach to the storage. Then, in March 2023, Holcim US said that it was working with TotalEnergies to build solar power capacity and a battery energy storage unit at the Florence cement plant in Colorado. TotalEnergies will install, maintain and operate a 33MW DC ground-mounted solar array and a 38.5MWh battery energy storage system at the site. Operation of the renewable energy system is expected to start in 2025.

Away from electrical batteries, the other approach to energy storage at cement plants that has received attention recently from several quite different companies has been thermal batteries. The two prominent groups using them at different scales are Rondo Energy and Synhelion. The former company has developed its Heat Battery technology, which uses refractory bricks to absorb intermittent renewable energy and then supply the energy back as a steady stream of hot gas for use in a cement plant mill, dryer, calciner or kiln. Both Siam Cement Group (SCG) and Titan Cement have invested in Rondo Energy. In July 2023 SCG and Rondo Energy said that they were planning to expand the production capacity of a heat battery storage unit at a SCG plant to 90GWh/yr. Synhelion, meanwhile, has been working with Cemex on using concentrated solar power to manufacture clinker. It achieved this on an ‘industrially viable scale’ in August 2023. It has since been reported that the companies are working on building a small scale industrial plant at Móstoles near Madrid by 2026. Crucially for this discussion though, the process also uses a thermal energy storage unit filled with ceramic refractory material to allow thermal energy to be released at night, and thus ensure continuous operation.

The examples above demonstrate that some cement companies are actively testing out storing energy at scale. Whilst this will not solve the cement sector’s process emissions, it does potentially start to make using renewable energy sources more reliable and reduce the variable costs of renewable power. Whether it catches on remains to be seen. Most of these kinds of projects have been run by power companies and that is where it may stay. It is instructive to note that Reon Energy was the only company to state that its battery-based energy storage system has a life-span of 8 - 12 years. Our current vision of a net-zero future points to high electrical usage but it may be shaped by how good the batteries are… from our phones to our cars to our cement plants.

US: Holcim US has rebranded its businesses in Boston, Massachusetts, to unite them under the Holcim name. Resources News has reported that Lafarge Cement, which operates the Charlestown cement terminal, as well as building materials producer Aggregate Industries, will rebrand as Holcim US.

Holcim US’ Northeast and Great Lakes regional senior vice president and general manager Domenico D'Aqui said "With the integration of local legacy operations into Holcim, the Boston area will see expanded benefits of construction projects made from innovative materials, such as ECOPact reduced-CO₂ concrete, that not only build needed infrastructure but also meet ambitious sustainability targets."

US: Holcim US has announced plans for a 25MW solar power plant to serve 75% of the electricity needs of its Alpena cement plant in Michigan. The company says that the installation at the Alpena plant will be the largest in the US Midwest Region. Holcim US chose NorthStar Clean Energy to build the array, which it says will eliminate 25,000t/yr of CO₂ emissions.

Other planned projects at the Alpena cement plant include an upgrade to the plant's dock in order to accommodate larger vessels and reduce the number of trips in its Great Lakes transport operations.

Holcim US' senior vice president, manufacturing, Michael Nixon said “As Holcim is showing in Alpena, the path to net-zero carbon emissions requires a blend of proactive solutions. Whether it’s using alternative fuels or implementing renewable energy from solar power, we are committed to reducing our reliance on fossil fuels — a goal that will benefit the environment as a whole and the Alpena community we have called home for more than 115 years.”

US: Holcim US has joined the New York Value of Distributed Energy Resources (VDER) program as part of its plans to enter Purchase Power Agreements (PPA) so that it can use more renewable energy sources. The scheme is intended to help support its investment in on-site renewable energy generation.

Atl Martinez, the Vice President of Procurement at Holcim North America, said “Holcim US is focused on driving significant progress to meet our Green Growth Strategy goals, so we consistently evaluate our environmental impact and opportunities to incorporate more sustainable solutions into our operations.” He added, “Through the New York VDER program, we support not only our ongoing investment in on-site generation but also community solar projects that help drive greener outcomes for all.”

The company will host three separate solar arrays on Holcim's non-mineable aggregate sites. These sites, operating in conjunction with various other offsite arrays within the Holcim VDER agreement, are expected to generate more than 80GWh/yr of energy. Energy generated from these sites will effectively power seven aggregate and cement sites through renewable energy credits.

Other work by Holcim US towards net zero includes its participation in the Northeast Regional Clean Hydrogen Hub program. The company has also expanded its renewable portfolio to include a 40MW battery storage system and 78MW of solar arrays in Ohio, Maryland and Arkansas. In late 2022, it entered into its first virtual power purchase agreement (VPPA) with the Electric Reliability Council of Texas (ERCOT).

US: Holcim US has inaugurated a waste tyre processing plant at its Alpena cement plant in Michigan. The facility will process 22,000t/yr of tyres into refuse-derived fuel (RDF) for use at the cement plant. Holcim US partner Geocycle will collect, pre-process and deliver the tyres to the new facility.

Holcim US’ North regional senior vice president of manufacturing Michael Nixon said "Holcim has invested more than US$100m in eco-friendly technologies at the Alpena plant in the past 15 years. The tyre-derived fuel facility is another strong demonstration of our commitment to reducing emissions."

US: Holcim US has joined the Department of Energy's (DOE) 'Better Climate Challenge' to reduce CO₂ emissions and save energy. It is the first cement producer to commit to the DOE program. The subsidiary of Switzerland-based Holcim plans to power the electrical operations at 13 cement plants in the country with 100% renewable energy by 2030 and to reach net zero CO₂ emissions by 2050. As part of the 'Better Climate Challenge' it has committed to reduce CO₂ emissions in the US by at least 25% by 2033.

Examples of current renewable power usage at Holcim US cement plants include the installation of three onsite wind turbines at the Paulding plant in Ohio that generate 11,500MWh while a forthcoming solar unit at the Hagerstown plant in Maryland will generate up to 18,440MWh. All 13 Holcim cement plants will conduct reviews to identify projects that could contribute to meeting goals of the challenge.

With grant support from the DOE, Holcim is also investigating the feasibility of using carbon capture utilisation and storage (CCUS) at its cement plants in Portland, Colorado, and Ste. Genevieve, Missouri. In addition to involvement in the Better Climate Challenge, Holcim US is a continuing partner of the DOE's 'Better Plants Challenge', sharing facility-level energy data and solutions to help guide other industrial companies with implementing energy solutions in their facilities.

US: Holcim US has appointed TotalEnergies to install, maintain and operate a 33MW solar power plant and 38.5MWh battery system at its Florence, Colorado cement plant. By storing energy with the battery system, the plant can relieve demand on the grid at peak times. Holcim will receive roughly 71,000MWh/yr of renewable energy under a minimum 15-year power purchase and storage services agreement (PPSSA). The partners expect the new systems to reduce the plant's CO₂ emissions by 40,000t/yr and its energy consumption by 40%.

Holcim North America’s vice president for procurement Atl Martinez said "As we work to accelerate green growth across the US, it's critical that we come to the table with partners who share similar goals around circularity and renewable energy. This initiative with TotalEnergies demonstrates an ongoing determination to transform our operations and lower our carbon footprint. It's a milestone investment that will decrease our reliance on other sources of energy and shrink our utility costs through a powerful combination of clean energy and efficient operations."
