Storing energy at scale at cement plants
27 September 2023Taiwan 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.

Ceremony for cement plant project in Kattakurgan
27 September 2023Uzbekistan: Hengyuan Cement has held a ground-breaking ceremony at the site of its up-coming cement plant in the Kattakurgan district of Samarkand. The plant, a joint-venture between Chinese and Uzbek partners, will have a capacity of 3Mt/yr and cost US$350m to construct. Cement will be sold in the local market and, according to developers, exported to as far afield as the European Union.
At the opening ceremony, the Hokim of Samarkand region Erkinjon Turdimov and Chinese partners noted that cooperation between Uzbekistan and China has been developing steadily in recent years. The project will lead to 600 new direct jobs. The long-awaited cement plant was first announced in 2018, but has repeatedly been delayed, particularly by the Covid-19 pandemic.
China: Taiwan Cement (TCC) commissioned a 107MWh energy storage project at its Yingde plant in Guangdong province in August 2023. Subsidiary NHOA Energy worked on the project that linked the battery storage capacity to a 42MW waste heat recovery (WHR) system and a 8MWp solar photovoltaic unit. It uses lithium iron phosphate batteries supplied by Ningde Times.
The company’s say that the project is one of the largest industrial microgrids in the world. It is intended to provide energy flexibility to the cement plant by using NHOA Energy’s proprietary energy management system to manage peaks in energy demand and acting as a backup for critical equipment to avoid damage caused by sudden blackouts.
The NHOA Energy storage project is expected to store about 46000MWh/yr of electricity and save just under US$3m/yr in electricity costs. The system will also support the Guangdong Provincial Government’s energy storage development policy and be eligible to associated subsidies of over US$350,000/yr.
Giuseppe Artizzu, the chief executive officer of NHOA Energy, said “NHOA Energy’s proprietary energy management system will optimise the generation and consumption profile of the industrial microgrid, while also supporting the regional grid towards its 100% green energy objective, taking the energy transition in the area one step forward in total accordance with NHOA Group’s and TCC’s shared mission of fostering a positive change for the future of our planet.”
Bangladesh/India: The completion of an upgrade project to Chhatak Cement’s plant has been thrown into doubt due to uncertainty about securing limestone from India. The plant still needs to build a new 17km ropeway conveyor and this has been delayed due to failure to obtain permission on the Indian side of the border, according to the Daily Star newspaper. It is also facing problems procuring limestone in India due to on-going legal proceedings on environmental grounds between exporters in Meghalaya and the government. The Supreme Court of India granted permission for exports in 2022 but the case is still pending. In addition, plans to install a gas line from Sylhet to the plant has not started yet either.
The state-owned cement producer is run by the Bangladesh Chemical Industries Corporation (BCIC). It originally announced in 2016 that it was spending over US$100m to build a new 1500t/day dry production line at the plant to replace an old wet production line. Although the old line originally had a production capacity of 233,000t/yr, it had fallen to around half of this. However, despite the construction of new silos and other equipment at the site, the unit has not been operational since early 2020. The new line was originally planned to start operation in 2020 but this was delayed until 2023. The BCIC has now proposed that completion of the project be extended to mid-2025.
The India Cements to commission upgraded grinding unit at Sankar Nagar cement plant imminently
22 September 2023India: The India Cements expects to commission the upgraded grinding unit at its Sankar Nagar cement plant in Tamil Nadu later in September 2023. Hindu BusinessLine News has reported that the producer is undertaking the upgrade in order to increase efficiency and lower the plant’s operating costs. The producer has hired US-based Boston Consulting Group to ascertain other possible improvements to three of its plants in Andhra Pradesh and Telangana. At its Chilamkur cement plant in Andhra Pradesh, it is installing a waste heat recovery (WHR) system, scheduled for delivery in early 2024. FLSmidth and ThyssenKrupp Industrial Solutions are both reportedly conducting ‘detailed studies’ for possible future projects for The India Cements.
ACC fires kiln at new Ametha cement plant
14 September 2023India: Adani Group subsidiary ACC has started commercial clinker production from the kiln of its new Ametha cement plant in Madhya Pradesh’s Katni District. BQ Prime News has reported that the kiln line has a clinker capacity of 3.3Mt/yr. It is capable of co-processing up to 15% alternative fuel (AF). The plant is also equipped with a 1Mt/yr grinding unit and a 16.3MW waste heat recovery (WHR) plant.
The Ametha cement plant raises ACC’s installed cement and clinker capacity by 9.8% to 37Mt/yr.
Reconfiguration in the US cement market
13 September 2023The big US news this week has been that Summit Materials and Argos USA are planning to merge their operations. The new organisation will operate six integrated cement plants with a production capacity of 8.4Mt/yr, based on Global Cement Directory 2023 data. The companies say that this will make them the fourth biggest cement producer in the country, at 11.8Mt/yr, based on grinding capacity, and the largest domestically-owned operator. Additionally, the combined entity will also hold just under 5Bnt of aggregate reserves, 224 ready-mixed concrete (RMX) plants and 32 asphalt plants.
The deal is expected to close in the first half of 2024 subject to the usual regulatory clearances and shareholder approval. At this point Argos should own approximately 31% of the new company and Summit Materials’ shareholders will be the majority owner. Although, if we remember anything from the Lafarge-Holcim merger from nearly a decade ago, it is that if the share prices between the two companies diverge too much in the next six months then that proportion may change. In simple terms that split for Argos USA is in the region of where one might expect it to be given that Argos USA made 39% of the combined revenue for both itself and Summit Materials in 2022 and 28% of the combined earnings.
The two companies complement each other well for the purposes of forming a new heavy building materials concern. Summit Materials reported revenue of US$2.41bn in 2022, with 30% deriving from its aggregates businesses, another 30% coming from RMX and about 20% from paving. Cement generated US$341m, or 14%, of total revenue. By contrast Argos USA reported revenue of US$1.57bn in 2022 from a business just concerning cement and concrete. Geographically, Summit Materials’ integrated plants are in the Midwest, in Iowa and Missouri respectively, and its cement terminals follow the Mississippi River from Minneapolis to New Orleans. Notably, it made the point in the merger announcement that the deal would reduce the seasonality of its cement business. Argos USA’s plants and terminals are mostly spaced out in the Southern states with its plants in Alabama, Florida, South Carolina and West Virginia.
It goes against recent trends for a US-based company to be increasing its share in the domestic cement market, although it has resorted to teaming up with a Colombia-based one to do so. Usually it is foreign-headquarted companies making moves in the US. For example, Ireland-based CRH is in the final stages of switching its primary listing to the New York Stock Exchange. Its head Albert Manifold described the US construction market as going through a “golden age” earlier in the year whilst trying to sell the stock market move at the company’s annual general meeting. Meanwhile, there have been various smaller acquisitions such as Peru-based UNACEMs’ agreement to buy the Tehachapi cement plant in California from Martin Marietta Materials in August 2023.
Given the ongoing importance of the North American market for the international cement producers it is not surprising that merger and acquisition activity has been taking place. Each of the four largest US-based cement producers performed well in the first six months of 2023, increasing both revenue and earnings significantly. However, the picture is mixed. The Portland Cement Association (PCA) forecast at the start of 2023 that cement consumption would decline in the second half of 2023 due to a worsening general economic outlook. The downturn was estimated to be brief though as interest rates were expected to dip and infrastructure spending to rise in 2024. Half-year data from the United States Geological Survey (USGS) supported this view as shipments reached an estimated 51.0Mt, a slight decrease from the same period in 2022. The cement companies have made money so far in 2023 partly by raising their prices. Yet, some segments of the residential homebuilding market have also driven demand despite the general economic picture.
One last thing to consider is how much thought was given to the carbon risk of forming a new heavy building materials company in a developed economy in the 2020s. Sustainability receives a mention in Summit Materials’ investor presentation in the form of current achievements such as switching to blended cements or reducing fossil fuel usage but there is no suggestion that any serious investment to curtail process emissions is expected any time soon. However, one could make the case that the enlarged company might benefit from synergistic effects if it were forced to spend more on CO2 emission reduction. This proposed merger concerns two existing organisations teaming up rather than new equity entering the arena. In this context it will be worth noting whether the next cement industry merger or acquisition in the US or Europe will involve existing companies or new entrants.
US: Terra CO2 plans to build its first commercial-scale supplementary cementitious materials (SCM) plant in Texas. The plant will have a production capacity of 240,000t/yr. Asher Materials secured an exclusive market license to operate the plant. Terra CO2’s SCM can replace up to 40% of cement content in concrete. Asher Materials will produce the materials from silicate rock from existing local aggregates operations.
Terra CO2 chief science officer DJ Lake said "From start to finish, we've designed a system to create large-scale impact in the real world. Our game-changing production process converts affordable, abundant and local raw materials to cementitious material that meets rigorous performance standards.” Lake continued “True sustainability will come from deep innovations in materials and technology and not from incremental improvements to the existing cement supply chain."
Dangote Cement to raise alternative fuel substitution rate to 25%
13 September 2023Nigeria: Dangote Cement plans to raise its alternative fuel (AF) substitution rate across its Nigerian operations to 25%. The Punch newspaper has reported that the producer consumed 34,800t of AF during the first half of 2023.
Obajana cement plant head of sustainability Eseosa Ighile said “We are working towards installing AF feeding systems in all our operation lines by 2024.”
