Europe: Vattenfall has signed a commercial agreement with Cemvision to supply near-zero-CO₂ cement for its onshore wind infrastructure projects across Europe from 2028. Cemvision’s Re-ment Massive product will be prioritised by subcontractors and has the potential to cut emissions by up to 95%, according to the company. Deliveries will come from Cemvision’s first industrial-scale plant and follow a 2024 letter of intent signed by the two companies.

Cemvision CEO Oscar Hallen said “This long-term agreement for the supply of our near-zero cement is a foundational step in transforming the cement market, and we are proud to take the partnership with Vattenfall to the next level. Our cement is one of the most cost-efficient ways to decarbonise construction. Moving from pilot to commercial action is how the transition becomes real.”

Vattenfall aims for 10% of its cement and concrete purchases to be near-zero by 2030, with the deal making it possible to reach 20% by 2028 and supporting a 50% supply chain emissions reduction by 2030.

Italy: Cementeria Costantinopoli has placed an order with Vestas for a 10MW wind project to supply renewable energy directly to its cement plant in Basilicata. The on-site wind farm will cover around one third of the plant’s electricity needs. The project includes three V117-3.45MW turbines and a 10-year Active Output Management 4000 service agreement. Turbine delivery and commissioning are scheduled for the fourth quarter of 2026.

Vestas Italy general manager Francesco Amati said “This project marks a milestone for Vestas in Italy as it is the first of its kind in the country to exclusively power an energy-intensive cement plant with clean wind energy. We are proud to deliver the technology solution that will reduce the plant’s environmental footprint and reliance on external power.”

Renewables reportedly generated more power than coal in the first half of 2025. Energy think tank Ember put out a report this week, which showed that solar and wind generation also grew faster than the rise in electricity demand in the first half of 2025. Global electricity demand rose by 2.6% year-on-year, adding 369TW. Solar increased by 306TW and wind by 97TW. Both coal and gas generation fell slightly, although a rise in other fossil fuel generation slowed the decline further.

Tellingly, fossil fuel generation fell in both China and India. Indeed, China added more solar and wind than the rest of the world combined, cutting its fossil fuel generation by 2% or by 58.7TWh. In India, renewables grew at the expense of fossil fuels, but demand growth was relatively low at 12TWh. In the US and the European Union (EU) fossil fuel generation actually increased. In the US, this was due to demand growth outpacing new renewable power. In the EU, weaker wind and hydroelectric output led to a greater reliance on coal and gas.

Meanwhile, a separate report by the International Energy Agency (IEA), also out this week, predicts that installed renewable power is likely to more than double by 2030 even as the sector navigates headwinds in supply chains, grid integration and financing. The IEA forecasts that global renewable power capacity will increase by 4600GW by 2030, roughly the equivalent of adding the total power generation capacity of China, the EU and combined. Solar photovoltaic (PV) will account for around 80% of the global increase in renewable power capacity over the next five years, followed by wind, hydroelectric, bioenergy and geothermal. Solar PV is expected to dominate renewables’ growth between now and 2030, remaining the lowest-cost option for new generation in most countries. Wind power, despite its near-term challenges, is still set for considerable expansion as supply bottlenecks ease and projects move forward, notably in China, Europe and India. However, the IEA’s outlook for global renewable capacity growth has been revised downward slightly compared to 2024, mainly due to policy changes in the US and in China.

This is all very well but what does it mean for the cement sector? At face value, possibly not much anytime soon. Both Ember and the IEA are talking about domestic electricity generation, not industrial. Ember reckons that half the world’s economies may have already peaked in fossil fuel power generation, but usage rates are still high. Prices of fossil fuels may even subsequently come down - to the benefit of industrial users such as cement plants. Yet, carbon taxes should, in theory, discourage increased usage - if they are working correctly.

Market distortions should not be discounted though. Some readers may recall what happened with carbon credits in the earlier stages of the EU emissions trading scheme. Free carbon allowances, calculated during the boom years of 2005 - 2007 when production was maxed out, were far too much to cover production during the resulting economic crisis. The sale of extra allowances provided many plants with a nice little earner and did little to encourage decarbonisation. Carbon capture is likely to require large amounts of electricity, but cheaper energy from renewables may help.

However, take a look at renewable energy stories in the Global Cement website news so far in 2025 and there are nearly 30 solar-related and seven wind-related ones. Cement companies are busily adding renewable capacity to reduce the cost of their electricity. This week, for example, Equator Energy commissioned a 10MW captive solar power plant at Mombasa Cement’s Vipingo plant in Kenya. Last week, Southern Province Cement in Saudi Arabia signed a 25-year solar energy power purchase agreement for its Bisha cement plant. Lest one forget, Saudi Arabia was the largest exporter of crude oil among Organization of the Petroleum Exporting Countries (OPEC) members in 2023 at 6,659,000 barrels/day. If a cement plant in Saudi Arabia is investing in renewables, then one might suspect a change in the global energy mix is occurring.

Electricity accounts for around 12% of the energy demand at a cement plant. Nearly two-thirds of that demand comes from either grinding raw materials or cement. Then, as mentioned above, carbon capture is expected to increase the demand for electricity. One estimate reckons it will increase electricity consumption by 50 - 120%. Renewables are expected to bring down the price of electricity but demand will also grow.

So… expect more renewable projects linked to cement plants.

Pakistan: Burj Clean Energy Modaraba (BCEM) and Power Cement (PCL) have signed a ‘green’ captive power transaction, a US$5.3m project to establish a 7.5MW wind captive power plant.

The deal is backed by a finance facility arranged by The Bank of Punjab, with participation from the National Bank of Pakistan and Pak Kuwait Investment Company. Power Cement said the initiative will allow it to generate clean and reliable electricity on-site, reducing reliance on fossil fuels and supporting Pakistan’s wider clean energy goals.

Pakistan: Lucky Cement commissioned 28.8MW of wind power at its south Karachi plant in the second quarter of the 2025 financial year, bringing its total renewable energy portfolio to 160MW. This includes 74MW of solar and 56MW of waste heat recovery (WHR).

The company said renewable sources now cover more than 55% of its cement operations’ electricity demand, with the remaining 45% supplied by the national grid.

Lucky Cement also reported that cement dispatches rose by 8% year-on-year in the 2025 financial year, driven largely by stronger exports. The company said that it has retained its position as Pakistan’s largest cement exporter, with African markets accounting for the bulk of volumes.

India: UltraTech Cement has commissioned a 7.5MW hybrid renewable energy project at its Sewagram cement plant in Gujarat. The on-site system combines bifacial solar modules with trackers, wind power and battery storage to provide uninterrupted energy without reliance on the grid. The project was developed with energy provider Gentari. The company aims to increase the share of renewable energy in its power mix to 65% by 2027 and 85% by 2030. As part of its RE100 commitment, UltraTech aims to meet 100% of its electricity needs through renewable sources by 2050.

Ukraine: Renewable energy company Elementum Energy and Ukraine-based cement producer CEMARK, part of CRH, signed a one-year financial power purchase agreement to stabilise electricity prices, supplied from the 100MW Dniester Wind Farm to one of CEMARK’s plants.

It is the second such agreement signed by Elementum Energy, following a pilot deal in January 2025. CEMARK energy resources procurement manager Maryna Boyaryntseva said electricity costs are “one of the key components in the cost of cement and require constant attention and the introduction of new tools to influence price formation.”

Elementum Energy said one- to two-year price stabilisation tools are attractive to businesses in wartime, because they allow for a cost forecast and risk reduction without committing to a longer-term contract.

Pakistan: Power Cement will build a 7.5MW wind power plant using Goldwind turbines under a rental model, with commissioning targeted in the 2026 financial year.

The new facility will supply 11% of the producer’s energy demand. Power Cement currently sources 34% and 6% of its energy needs from waste heat recovery and solar, respectively. The company has a total cement production capacity of of 3.37Mt/yr.

Pakistan: Thatta Cement commissioned its 4.8MW wind power project at its plant in Thatta, Sindh, on 3 April 2025. The project was reportedly completed ahead of schedule and brings the producer’s total renewable energy capacity to 9.8MW.

Brazil: Buzzi subsidiary Cimento Nacional has signed a 15-year power purchase agreement with renewable energy provider Casa dos Ventos for 65MW/yr of wind power from the 756MW Serra do Tigre and 360MW Babilonia Sul wind farms. The agreement will supply 100% of the producer's electricity requirements in its Brazilian facilities.

The Serra do Tigre wind farm is currently under construction in Rio Grande do Norte, but the Babilonia Sul wind farm is operational in Bahia.
