US: Vineyard Offshore has agreed to buy 2000t of cement from Sublime Systems, a Massachusetts startup planning a US$150m ‘carbon-free’ cement plant in the city. The cement will be used for turbine platforms and onshore civil works within the Vineyard Wind 2 project, aiming to reduce its carbon footprint. This agreement is contingent on the project's selection in upcoming solicitations.

Europe: A joint statement by Cefic, Cembureau, Eurofer, Eurometaux and WindEurope has called for accelerated wind deployment as part of a new industrial deal to further support the Green Deal in the European Union (EU).

The organisations say that Europe's energy-intensive industries, like cement and steel, are vital for the wind energy supply chain. However, they assert that current policies lack frameworks that effectively support these industries, which have faced production curtailments due to the energy crisis. Addressing these challenges is fundamental to a new Industrial Deal for Europe, aimed at boosting renewable energy deployment to reduce energy costs. According to the International Energy Agency, the growth in solar photovolatics and wind capacity from 2021 to 2023 helped keep electricity prices lower than they would have been otherwise. Coupling the EU Green Deal with an industrial deal is seen as a strategy to provide regulatory stability, encourage investments in decarbonisation, and enhance competitiveness.

Koen Coppenholle, CEO of Cembureau, said "Cement is a critical component in the construction of wind turbine foundations and their recycling, while the growth of renewable energy is indispensable to achieve the cement sector’s net zero ambition. We look forward to a good cooperation with the wind energy sector to support a strong EU industrial policy and help building the business case for decarbonisation investments," said Coppenholle.

Spain: Capital Energy has won a contract to supply renewable energy to Cementos Alfa’s Mataporquera cement plant in Cantabria. The energy company will supply 80,000MWh/yr to the subsidiary of Cementos Portland Valderrivas under the contract, initially from five local wind farms. The contract takes the form of long-term power purchase agreement (PPA), under a self-consumption scheme with surpluses.

India: Adani Group subsidiary Ambuja Cements plans to invest US$722m in renewable energy projects to help decarbonise its cement production. The producer has a renewable power capacity target of 1000MW, through solar and wind projects, by the end of the 2026 financial year. The proposals include a 600MW solar power project and 150MW wind power project in Gujarat, and a 250MW solar power project in Rajasthan. The company also plans to increase its waste heat recovery (WHR) capacity to 397MW by late 2028 from 103MW at present.

Ajay Kapur, the chief executive officer of Adani Group’s cement business, said "This strategic investment reaffirms our steadfast commitment to sustainable practices. We are not just aiming for a substantial increase in green power capacity but setting the stage for a transformative shift in the cement industry. They align not only with our growth trajectory but also with the national objective of decarbonisation and greener future and this helps us become competitive and sustainable."

Adani Group announced in mid-December 2023 that it was committed to investing US$100bn in the decade to the end of 2033 towards transitioning its operations to net zero CO₂ emissions by 2050.

Poland: Cemex Polska awarded an eight-year contract to Statkraft to supply wind and solar energy for its cement plants. The parties signed a corporate power purchase agreement (CPPA), under which Statkraft will meet 30% of Cemex Polska’s plants’ energy consumption, beginning on 1 January 2025.

Cemex Polska director cement operations Tadeusz Radzięciak board member “The concluded contract is important for Cemex on several levels. The contract ensures stable supply of a large volume of electricity, while at the same time securing a guaranteed, predictable level of prices for supplied energy in the long term. This is particularly important in the context of the rapid and unpredictable changes in energy prices on the European and Polish energy markets recorded in the last several months. In addition, the partnership with Statkraft is crucial in the context of achieving the Cemex's sustainability goals. After all, sourcing energy from renewable sources enables a significant reduction in the carbon footprint of our production facilities.”

Pakistan: The board of directors of Lucky Cement has approved US$37.1m-worth of investments in the construction of renewable energy infrastructure at the company’s Karachi and Pezu cement plants. The producer plans to build a 6.3MW solar power plant and a 28.8MW wind power plant at the Karachi plant in Sindh and a 2.5MW solar power plant at the Pezu plant in Khyber Pakhtunkhwa. Pakistan Company News has reported that the board also empowered Lucky Cement to evaluate its participation in the equity of its diversified industrial manufacturing subsidiary, Lucky Core Ventures.

Taiwan Cement said this week that it is aiming for cement to account for less than half of its sales by 2025. At the annual shareholders’ meeting chair Nelson Chang defended the cement sector as a core business but said that the company was expanding more into the green energy sector through its energy storage and vehicle charging lines. Chang directly linked the strategy to growing carbon taxes around the world, such as the European Union Emissions Trading Scheme, where the carbon price has been occasionally close to pushing past Euro100/t since early 2022. Taiwan Cement formed a joint venture with Türkiye-based Oyak Group in 2018 that runs Cimpor in Portugal.

Taiwan Cement’s plan to decrease its reliance on cement is becoming a familiar one. Holcim notably revealed in 2021 that it was growing its light building materials division. Its cement division represented 60% of sales in 2020 with concrete and aggregates making up most of the rest to 92% and the remaining 8% on other products including light building materials. This started to change with the acquisition of roofing and building envelope producer Firestone Building Products in 2021. Other similar acquisitions have followed. Holcim’s current target is to grow the Solutions & Products division to around 30% by 2025, with cement reduced to somewhere between a third and half of sales. Earlier this year Japan-based Taiheiyo Cement said it was doing a similar thing as part of its medium-term strategy to 2035. In its case cement represented 70% of its sales in 2022 but it is now aiming to reduce this to 65% by 2025 and 50% by 2035.

A common pattern for the business composition of European cement companies is a mixture of heavy building materials made up of cement, concrete and aggregate. However, not every cement company follows the same route. Some cement companies are simply parts of larger conglomerates. UltraTech Cement, for example, is mostly just a cement company. However, it is also part of Aditya Birla Group, which runs a wide range of industries including chemicals, textiles, financial services, telecoms, mining and more. Depending on how one looks at it, UltraTech Cement’s cement business ratio is large or Aditya Birla Group’s ratio is small. Siam Cement Group (SCG) in Thailand is another example of a cement producer operated by a conglomerate with other major businesses.

A different approach that some cement producers take is to mix cement production with complimentary businesses outside of heavy building materials. A good example of this is Votorantim Cement in Brazil, which manufactures cement and steel. Companhia Siderúrgica Nacional (CSN) is another Brazil-based cement producer that is also well known for steel production. Adani Group in India, meanwhile, was well known for logistics, power generation and airports before it purchased Ambuja Cements and ACC from Holcim in 2022.

The driver for cement companies looking to reduce cement as a proportion of their businesses has varied between the three examples presented above. Holcim’s approach has been in response to growing European carbon costs but it also fits with a general desire to broaden its business as the company has sought to reshape itself following the merger between Lafarge and Holcim. Taiheiyo Cement’s plans also have a sustainability angle but the Japanese market has been in slow decline since the 1990s and this has been made worse by the spike in energy prices since 2022. Investing in new businesses makes sense for either of these reasons. Lastly, Taiwan Cement says it is taking action in response to carbon prices around the world. However, its proximity to many other large-scale producers in the Far East may also be a factor. Whether more companies follow suit and also start to reduce the ratio of their cement businesses remains to be seen. Yet, mounting carbon taxes and global production overcapacity look set to make more of the larger cement producers consider their options in certain places.

Argentina: Cementos Avellaneda has signed a memorandum of understanding (MoU) with energy provider YPF Luz for the construction of a new wind farm. Local press has reported that the planned plant will have a capacity of 63MW and be situated in Olavarría, Buenos Aires Province. There, it will supply 100% of the energy used in cement production at Cementos Avellaneda's Olavarría cement plant. The cement producer will transmit any surplus energy from the wind farm to its San Luis plant at La Calera, with the longer-term aim of becoming Argentina's first 100% renewably-powered cement company.

The partners will carry out technical and economic feasibility studies in mid-2023, and publish plans and budget before the end of the year.

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.

Poland: Lafarge Cement Polska has signed a 15-year power purchase agreement (PPA) with KGAL Investment Management. The KGAL ESPF 4 renewable energy fund will provide the cement producer with around 230GWh/yr of electrical energy from two onshore wind farms. These will be the 35MW Krasin unit, which opened in 2022, and the 27MW Rywald unit, which is scheduled to start feeding the local grid from October 2023. With this latest agreement in place, Lafarge Cement Polska will be able to cover over half of its electrical supply requirements from renewable sources.
