Taiwan: Taiwan Cement Corporation has signed a memorandum of understanding (MoU) with ThyssenKrupp Polysius. Under the MoU, the partners will implement carbon capture projects aimed at capturing 100,000t/yr (10%) of Taiwan Cement Corporation’s CO₂ emissions by 2030. This will involve the development of a new generation of pure oxygen carbon capture technology in Line 1 of Taiwan Cement Corporation’s Hualien Heping cement plant. This technology aims to increase the concentration of captured CO₂ to over 90% and reduce the energy consumption of carbon capture. The Hualien Heping plant project will conclude in 2026, with the commercialisation of the technology to follow before 2030. Taiwan Cement Corporation plans to supply its own captured CO₂ to various other industries, including industrial welding, chemicals and food processing.

Taiwan Cement Corporation chair Zhang Anping said "Cement has created the civilised society we live in today, and Taiwan Cement Corporation will continue to participate in energy transformation and support the development of future civilisation. This cooperation with Polysius, a golden brand in the cement industry, is to solve the problem of greenhouse gas emissions, creating the future not only for the cement industry but for the whole world."

Portugal: The Portuguese Competition Authority has approved Taiwan Cement Corporation (TCC)’s outright acquisition of Cimpor. Jingshi News has reported that TCC received the approval on 1 February 2024, enabling it to proceed with its acquisition of the outstanding 60% stake in Cimpor.

Portugal: The competition authority has opened a 10-day window for public comment after receiving notification of Taiwan Cement Corporation’s proposed outright acquisition of Cimpor. The procedure is open to companies and members of the public interested in registering criticism or favourable opinions on the effects of the deal on competition.

Taiwan Cement Corporation agreed to buy current majority shareholder OYAK Çimento’s 60% stake in Cimpor for Euro480m in November 2023.

Türkiye: Taiwan Cement Corporation (TCC) has concluded an agreement to acquire an additional 20% stake in OYAK Denizli Çimento from OYAK Çimento. Reuters has reported that this will raise TCC’s stake in the company to 60%. The deal aligns with a previous memorandum of understanding (MoU) between the two parent companies.

OYAK Denizli Çimento operates the 3Mt/yr Honaz cement plant in Denizli Province. It reportedly has an enterprise value of Euro1.4bn. OYAK Çimento bought the business from Eren Holding and Ireland-based CRH for US$400 – 450m in 2014.

Taiwan Cement Corporation (TCC) has struck a deal to take control of the Türkiye and Portugal-based parts of OYAK’s cement business. The arrangement will see TCC grow its share of the joint-venture business in Türkiye to 60% from 40% at present and it will fully take over the Cimpor joint-venture in Portugal by purchasing OYAK’s 60% stake. Overall TCC is expected to pay around Euro740m for its acquisitions. A final agreement on the deal is expected to be signed in early December 2023.

The proposed deal follows on from when TCC originally spent US$1.1bn towards setting up joint-ventures as a junior partner with OYAK back in 2018. The situation now appears to have reversed with TCC becoming the main owner of the cement business in Türkiye and the sole owner of Cimpor in Portugal. In Türkiye this gives TCC control over the largest cement producer with seven integrated plants, three grinding plants, 47 ready-mixed concrete (RMX) plants, three aggregate quarries and one paper packaging plant. In Portugal (and Cape Verde) this puts TCC in charge of three integrated plants, two inactive grinding plants, 42 RMX plants, 15 quarries, two mortar plants and a cement bag unit.

This contrasts with last week’s news that CRH is buying one cement plant in Texas (with associated assets) for US$2.1bn. TCC is taking control of 10 plants in Türkiye and Portugal for Euro740m. It is not a fair comparison given the woes of the Turkish economy in recent years, prior joint-venture business ownership and so on. Yet it is one more example of the changing nature of cement company ownership around the world since the mid-2010s.

The state of the economy in Türkiye may well be a factor for the change in ownership at OYAK and Cimpor as well as negative exchange rate trends. High inflation has caused problems in recent years, although the government changed its stance on avoiding putting up interest rates following the elections in May 2023. Yet, in a statement about the OYAK deal, chair Nelson Chang said that “companies that do not understand carbon will not survive in the future.” His company is about to spend Euro740m and become the fifth largest cement producer in the world on the assertion that it does understand carbon. Good luck!

Accordingly, the language in the press releases both OYAK and TCC have released is all about sustainable growth and reducing carbon emissions. However, the detail on how exactly they intend to do this is vague. What is clearer though is that OYAK is hoping that TCC invests in energy storage and related industries such as lithium-ion battery additive carbon black in Türkiye. To this end a TCC subsidiary and OYAK are collaborating on a carbon black plant in Iskenderun and further investments may be in the pipeline. TCC and OYAK are also responsible for a couple of calcined clay projects in Sub-Saharan Africa.

Readers may recall that the chair of Chang pronounced in June 2023 that TCC was aiming to diversify the business towards over 50% sales from non-cement sectors by 2025. However, the share from the cement business was around 68% in 2022 and this latest deal with OYAK will likely send it in the ‘wrong’ direction. The company already has a production capacity of around 77Mt/yr from its cement plants in China and Taiwan. Majority ownership of OYAK Çimento and Cimpor Portugal will bump this up to 99Mt/yr and put the company into the top five of the world’s largest cement producers by capacity.

The final question here is what kind of owner TCC intends to be to its growing cement businesses in West Asia and Europe. Publicly at least, it has come across as a backseat investor since 2018 although it has been a minority owner. This has now changed but it will be interesting to observe whether the subsidiaries in the west will be run at arm’s length or more closely and if TCC unifies its global branding and so on. Watch this space.

Türkiye: Taiwan-based Taiwan Cement Corporation (TCC) has signed a preliminary memorandum of understanding (MoU) with OYAK Çimento. Under the MOU, the parties will enter into negotiations over the transfer of a further 20% stake in OYAK Denizli Çimento to TCC. This will raise TCC’s stake in the company to 60%. Reuters has reported the total enterprise value of OYAK Denizli Çimento as US$1.42bn.

Taiwan: Asia Cement Corporation tested its waste wind turbine blade processing capacities using 12t of blades earlier in November 2023. The cement producer had previously processed 9t of waste turbine blades for use in its plants up to the end of October 2023. Asia Cement Corporation says that the waste consists of fibre-reinforced plastic (FRP), which is 60% silicon dioxide, calcium oxide and aluminium oxide and 40% polyester. The polyester can replace fossil fuels as alternative fuel (AF) for cement plants, while the other chemical compounds can serve as supplementary cementitious materials (SCMs).

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.

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.”

Europe: The EU has awarded a Euro49.9m grant under its Alternative Fuel Infrastructure Facility (AFIF) to Taiwan Cement subsidiary Atlante. The cement group said that Atlante will use the funds to building a fast and ultra-fast electric vehicle charging network in Europe.
