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.

Belgium: Holcim kicked-off its Go4Zero project at its Obourg plant on 16 May 2024 in an event attended by the Belgian Prime Minister Alexander De Croo and the European Commissioner for Climate Action Wopke Hoekstra. The €500m Go4Zero project, supported with €230m of funding from the European Union, will enable the integrated plant to reduce its CO₂ emissions by 30% by 2027 and to produce 2Mt/yr of CO2-free cement by 2029. When fully operational, the Obourg plant will capture 1.2Mt/yr of CO₂.

The Go4Zero project incorporates a number of approaches to achieve net-zero CO₂ cement. The centrepiece is an oxy-fuel combustion process to generate an easy-to-handle exhaust gas with up to 80% CO₂. This will be coupled to a cryogenic purification unit to generate a >99%-pure CO₂ stream .The project will also make use of waste heat recovery (WHR), new exhaust filtration equipment and Europe’s largest floating solar panel farm.

US: Cemex has entered an off-site renewable energy agreement for its Clinchfield Cement Plant with Georgia Power, securing about 25% of its power from solar facilities throughout the state, starting in 2025. The plant will offset roughly 10,000t/yr of indirect CO₂ emissions, contributing to a 58% reduction target in Scope 2 GHG emissions from its 2020 levels by 2030.

Senior Vice President of Cemex US Ernesto Felix said "Embracing solar power not only accelerates our own aggressive sustainability goals but also sets a powerful example for the entire industry. By integrating renewable energy solutions through Georgia Power, Cemex paves the way for a greener, more resilient future for generations to come."

India: Roofsol Energy has won a contract to supply solar power plants with a total capacity of 10.5MW for Shree Cement in Jharkhand and Uttarakhand, Saur Energy News has reported.

Roofsol Energy said “Shree Cement owns and operates cement grinding units in nine locations across India and owns production facilities in Rajasthan, Chhattisgarh and Karnataka and has operations in India and UAE. The company carries out power generation through waste heat recovery plants and now it is adopting solar plants as well.”

India: UltraTech Cement plans to acquire a 26% stake in O2 Renewable Energy for around US$2m. It is making the purchase to support the energy requirements of its plants from renewable sources, according to the Times of India newspaper. O2 Renewable Energy is currently building a solar power plant in Karnataka that is expected to generate 35 – 48MW.

Peru: Grupo Gloria subsidiary Yura plans to build a solar power plant in Yura, Arequipa. The plant will have a peak power of 31MWp and a nominal power of 27MW. The installation involves a 1.3km-long, 30kV transmission line. Gestión News has reported that the project is intended to reduce the costs associated with the company’s cement production.

Colombia: Cemex Colombia plans to source 42,900MWh/yr of renewable electricity for its Caracolita cement plant in Tolima from Celsia's upcoming 20MW solar power plant in Ibague. Upon the solar plant’s commissioning in 2025, this initiative will account for 25% of the cement plant's electricity needs.

Alejandro Ramirez, president of Cemex Colombia and Peru, said "Supplying our main cement plant in Colombia with solar energy will be a decisive step in our strategy to take advantage of renewable sources for cement production in Colombia."

Ricardo Sierra, CEO of Celsia, said "The company has 17 operational solar power plants totalling more than 300MW of installed capacity in Colombia." He added "Celsia’s target is to reach 1GW of photovoltaic projects under construction and development, some of which will deliver power to the grid, and others will benefit various industrial companies."

Croatia: Cemex Croatia has won contracts to install solar power plants at three of its facilities, co-financed by the EU's Modernisation Fund. The company will build new solar plants at Sv. Juraj and Sv. Kajo cement plants in Kaštel Sućurac and Solin, respectively, and at the Podsused production facility in Zagreb. The total investment is valued at €5m.

The solar power plants, with a combined capacity of 6.34MW, will be installed on the roofs of these facilities. The Sv. Juraj plant will receive a 3.79MW system worth €3m, the Sv. Kajo plant a 2.14MW system valued at €1.7m, and the Podsused facility a 0.41MW system costing about €318,000. The EU's Modernisation Fund will cover 60% of the costs for the Sv. Juraj and Sv. Kajo projects and 50% for the Podsused project.

"The savings that these measures will bring to us in terms of energy consumption will increase the efficiency of our production and reduce emissions from our operations. These are just some of the projects we are planning to achieve our climate goals" said Marijan Zekić, Cemex Croatia’s project and quality assurance manager.

India: UltraTech has installed floating solar photovoltaic panels at its Awarpur Cement Works plant on two water reservoirs, spanning 3600m². The reservoirs contain 7600 panels in total, which will generate 6173MWh/yr of solar energy. This initiative will reduce CO₂ emissions by 6000Mt/yr, equivalent to the sequestration benefits of 270,000 trees. The project enables UltraTech to use 100% of the generated power. Additionally, it will reduce water evaporation by up to 70% and has a minimal impact on local ecosystems.
