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.

Nepal: Hetauda Cement Industry resumed cement production on 7 April 2025 following a five-month suspension due to electricity shortages. According to general manager Nabin Kumar Karna, the plant requires 8MW/day of electricity to crush limestone.

The plant reportedly holds 1900t of coal in reserve and is acquiring a further 4000t through a bidding process. Though its capacity is 18,000 bags/day, current output is only 12,000 bags/day.

Japan: Mitsubishi UBE Cement Corporation has started a commercial-scale demonstration test using ammonia as a heat energy source in a cement kiln and calciner at Ube cement plant.

The project, supported by Yamaguchi Prefecture’s 2023 Carbon Neutral Complex Development Promotion Subsidy, follows an ammonia co-combustion test in 2023. In collaboration with UBE Corporation, a test facility for ammonia co-firing was installed.

The company has set a target of replacing 30% of its coal consumption with ammonia in the cement kiln, with similar levels targeted for the calciner by the end of the 2025 financial year. Mitsubishi UBE Cement is also planning further ammonia combustion tests with post-consumer plastics and other materials as energy sources.

Myanmar: The government will allow coal imports for cement plants from February 2025 in order to increase production, according to local news reports. Cement plants which need coal can apply for an import licence. The country's 16 private and three state-run cement plants produce less than 8Mt/yr, while national consumption exceeds 10Mt/yr, requiring cement plants to operate at full capacity.

South Korea: The cement industry in South Korea faces rising costs due to a rising won-to-dollar exchange rate following the attempted impeachment of the president, and transportation disruptions from a railroad strike. This is likely to lead to an increase in coal import costs, according to Chosun Biz news.

The ongoing strike by the National Railroad Workers Union has disrupted cement transportation, though stockpiles in metropolitan areas have mitigated immediate effects. However, prolonged strikes could force production halts.

Kim Seung-jun, researcher at capital market company Hana Securities, said “In the fourth quarter, cement production is expected to decrease by 14% compared to the same period in 2023.”

China: Shandong Province will curb cement production from 15 November 2024 to 15 March 2025 to reduce air pollution. The measure, similar to last winter's, was announced by the Province's industry and environment ministries. Shandong's reliance on inefficient captive coal-fired power plants means the measure could reduce coal demand significantly.

Belarus/Russia: Belarusian Cement Company has reached an agreement with the Republic of Khakassia for the delivery of regular coal shipments for its cement plants. The new agreement will ensure the weekly transport of approximately four trains loaded with coal from November 2024 - January 2025, meeting 100% of the demand of the Belarusian plants.

Pakistan: Pakistan Railways (PR) is planning the construction of a 105km railway line that will link the Thar Coal mines with a Port at Qasim. The project is being financed by the Sindh state and national governments and will be completed by October 2025.

An official from the Ministry of Railways said that the line would bolster the nation's bulk transportation capabilities, aligning with broader economic growth objectives and facilitating coal transportation across the country, supporting key industries like cement production. After the completion of the project, the rail network is expected to have the capacity to transport 10Mt/yr of coal, shifting Pakistan's reliance from imported to domestic coal sources.

India: Orissa Bengal Carrier has entered into a three-month contract to transport coal and petcoke for Shiva Cement, a subsidiary of JSW Cement, effective until 31 December 2024. The company has not disclosed the value of the contract.

Taiwan: Taiwan Cement Corporation, one of the island's largest coal importers, will completely halt its cooperation with Russia, according to The Moscow Times. This decision exacerbates the challenges faced by Russian coal exporters, who have already seen a nearly 12% decline in exports from January to July 2024. Since spring 2023, Taiwan has purchased more than 10Mt of Russian coal, accounting for nearly 20% of the island's total coal imports.
