Burkina Faso: The stone laying ceremony took place on Thursday 8 August 2024 at Ciments de l'Afrique’s (CIMAF) new calcined clay production unit and solar power plant at its plant in Ouagadougou, Burkina Faso. The calcined clay unit is valued at US$50m, while the solar power plant cost US$5.5m, reports Burkina 24. Completion is expected by August 2026.

Ibrahim Traore, president of Burkina Faso, said “The accompanying solar unit should make it possible to reduce production costs and we hope that in a few years, this technology will become popular and will make it possible to reduce cement costs.”

Anas Sefrioui, chair and CEO of CIMAF Group, said “The calcined clay that we will produce here in Burkina will serve as an alternative raw material to imported materials, particularly clinker.”

India: Oriana Power has received an order for a 40MWp solar power plant in Rajasthan from a cement producer. The project is valued at US$18m. Oriana will provide engineering, procurement and construction, alongside the commissioning, operation and maintenance of the plant. The plant is scheduled for commissioning in April 2025, with a subsequent operation and maintenance period of 25 years.

India: Shree Cement says that it has reached 1GW captive power capacity across its plants, after commissioning a new 19.5MW solar power plant at a facility in Andhra Pradesh. Renewables account for 499MW (50%) of the total. Shree Cement says that its investments in renewables to date total US$479m. NBM & CW News has reported that the company has current planned new investments worth US$120m in renewables. This will cover 132MW-worth of solar, 36MW of wind and 34MW of waste heat recovery power capacity.

Germany: Rohrdorfer has started operation of a new photovoltaic (PV) unit at its Rohrdorf cement plant near Rosenheim in Upper Bavaria. The rooftop PV installation comprises 1000 modules, covers around 2000m2 and has a peak output of 400kW. The construction time of the solar panels took five weeks. Modules supplied by Hecker Solar were installed by Elektro Ecker.

The cement plant has produced around one third of its electricity requirements via a waste heat recovery unit since 2011. Rohrdorf Group aims to generate 30% of its electricity from renewable sources as a whole by 2033.

India: Dalmia Cement (Bharat) has signed a power purchase agreement with BluPine Energy to establish a 47MW solar power plant in Karnataka. The plant will generate approximately 94 million kWh of electricity annually and reduce over 85,000t/yr of CO₂ emissions.

CEO of BluPine Energy, Neerav Nanavaty, said "The solar plant in Karnataka will not only produce clean energy but also foster local economic growth and support environmental sustainability. This project will help reduce operating costs and improve energy efficiency."

India: Dalmia Cement (Bharat) will acquire a 19.2% stake in Amplus Kaveri Solar for US$1.94m. This transaction is subject to customary conditions and is expected to complete within eight to nine weeks.

Thailand: B.Grimm Power has partnered with Siam City Cement (SCCC) to establish a joint venture named ‘Insee B.Grimm Solar.’ This collaboration aims to develop a solar rooftop project and a ground-mounted solar photovoltaic (PV) project within SCCC’s plant located in Saraburi province.

This project is expected to contribute to Thailand’s clean energy goals by reducing reliance on fossil fuels and integrating renewable energy sources into industrial operations. Specific details regarding the project’s capacity and timeline are not yet available.

Cemex announced last week that it will stop producing clinker at its Lloseta plant in Mallorca. Grinding activity at the site will continue, along with the shipment of bagged and bulk cement products. The company has framed the closure as part of its decarbonisation plans. The dismantling of the two preheater towers at the plant is scheduled to take place by the end of 2030. Cemex said that it will take this long to allow the cement plant to continue operating, as well as a neighbouring hydrogen unit and other nearby industrial units. The status of the Lloseta plant has been in question before. It was closed in early 2019 due to reduced cement demand and mounting European CO₂ emissions regulations. However, it reopened in 2021.

Readers may recall that Cemex España participated in the Power to Green Hydrogen Mallorca project. Land by the Lloseta cement plant was used to hold solar panels and a solar-powered hydrogen unit. Other partners in the project included energy suppliers Enagás and Redexis and renewable power and infrastructure company Acciona, among others. When the unit was commissioned in early 2022, it said it was the first solar power-to-green hydrogen plant in Spain. The link between Cemex and hydrogen is noteworthy given the cement company’s adoption of hydrogen injection as part of its alternative fuels strategy. Interestingly, Acciona planned to use a blockchain method to certify that hydrogen produced at the site was made using renewable energy sources. Heidelberg Materials also plans to use the same process to verify its evoZero brand of net-zero cement products in 2025. Another recent sustainability sector news story in Spain is the commissioning by Çimsa of a 7.2MW solar plant supporting its Buñol white cement plant in Valencia. The new installation is expected to supply about 18% of the plant’s energy needs.

On the corporate side of things, FCC revealed in mid-May 2024 that it was preparing to spin-off its cement and real estate subsidiaries into a new company called Inmocemento. The cement part of this is Spain-based Cementos Portland Valderrivas. The move is intended to bolster the values of the different parts of the business. The proposal will be put to FCC’s shareholders in late June 2024, with any resulting action taking place by the end of the year. The decision to separate FCC’s cement assets is reminiscent of the financial engineering Holcim has proposed with its US business. However, in this case the driver does not appear to be the disparity between the European and US stock markets.

Market data was also out this week from Oficemen, the Spanish cement association. Domestic cement consumption grew year-on-year in April 2024 but the year so far is looking weaker with consumption from January to April 2024 down by 4.5% year-on-year to 4.65Mt. This is below Oficemen’s forecast for 2024 where it expected a stagnant situation. However, there are eight more months to go. In 2023 cement consumption fell by 3% to 14.5Mt and exports declined by 7.5% to 5.2Mt. The association blamed continued underinvestment in both the public and private sectors due to economic instability since the Covid-19 pandemic. Graph 1 above shows the wider situation in the Spanish cement market over the last decade. The share of exports has declined and local consumption rebounded after 2020 but has declined since then.

These news stories provide a snapshot of what’s been happening in Spain recently in the cement sector. Oficemen’s prediction for 2024 is gloomy but local consumption has risen over the past 10 years. Exports have fallen but the cement association has started to spin the country’s decarbonsiation drive as a potential positive for the industry’s competitiveness generally. It’s hard to discern right now but there might be an advantage for an export-focused country that conforms to European standards in the future if it can hold onto its capacity. Admittedly, that’s a big if. This thinking along sustainability lines could be seen earlier in May 2024 when Cementos Molins Group rebranded itself as Molins. It described the rebranding as a bid to represent the wider range of construction products it manufactures and sells beyond cement. Oficemen has also pointed out that the local market has room for development given the relatively low cement consumption per capita in Spain compared to its peers. So, whatever happens next, there is likely to be room for improvement in the cement market.

Thailand: Siam Cement Group (SCG) has begun construction of a commercial heat battery supplied by Rondo Energy at its cement plant in Saraburi Province. It will be the first heat battery in Southeast Asia and the first heat battery deployed at a cement plant, according to the company. The project is a collaboration between Rondo Energy and SCG Cleanergy, a wholly owned subsidiary of SCG. Rondo Heat Batteries capture intermittent electricity and store energy as high temperature heat in bricks, to deliver continuous industrial heat and power on demand. This installation will convert local solar power into continuous zero-carbon heat and power for cement production.

President of Rondo Energy, Eric Trusiewicz, said "Electrification of cement production requires a large-scale and low-cost energy storage solution, as renewables are not available 24/7 but cement production needs to be."

Spain: Çimsa has invested €4.2m in launching a solar photovoltaic power plant to power its white cement plant in Buñol, Valencia. The solar plant has a capacity of 7.2MW and will supply about 18% of the energy needs for the cement plant.

The facility features 11,000 solar panels spread over 100,000m². This new solar power plant is expected to produce approximately 12GWh/yr of electricity, reducing CO₂ emissions by about 3000t/yr.
