Portland Cement Association lobbies US government to support industrial decarbonisation technology
02 March 2022US: The Portland Cement Association (PCA) has told the Department of Energy’s Advanced Manufacturing Office (AMO) that federal policy and support is vital to accelerate the deployment of technologies that can decarbonise the local industrial sector. In its comments to the office, the PCA said that it shares the Biden-Harris Administration’s goal of carbon neutrality by 2050 through its own Roadmap to Carbon Neutrality, which lays out a pathway to achieve this across the cement-concrete-construction value chain by 2050. However, it warned that without strong federal support the AMO’s timeline to reach carbon neutrality across industry was unrealistic due to the “significant technical, legal and economic challenges regarding technologies like carbon capture utilisation and storage (CCUS), and others including hydrogen fuel and kiln electrification.”
“Federal policy must accelerate the significant technology, funding, and market innovation needed for rapid decarbonisation while preserving economic growth and international competitiveness,” said Sean O’Neill, senior vice president of government affairs at the PCA. “The adoption of CCUS is key to achieving deep decarbonisation in the cement industry.”
The PCA added that with the right federal and state policies, CCUS could become scalable within 10 years but infrastructure, policy, permitting and funding challenges remain. It suggested that tax incentive reforms and the use of Department of Energy loan programmes could accelerate early investment and adoption of CCUS.
The use of hydrogen fuels and kiln electrification was mentioned but these technologies are seen as being at least 15 – 20 years away. The association said that hydrogen remained very expensive and there was little current infrastructure for the transport and storage of hydrogen. More research and development is required to start evaluating the efficacy of kiln electrification.

Holcim partners with Engie and National Institute of Applied Sciences Lyon to develop cement-based energy storage
03 February 2022Switzerland/France: Holcim is collaborating with Engie and and the French National Institute of Applied Sciences (INSA) Lyon to develop a cement-based energy storage technology to serve as an alternative to batteries. The solution will use cement hydration to store heat as energy and release it when needed in an infinitely repeatable cycle. The partners say that it will make energy storage local, safe, affordable and recyclable.
Holcim’s head of global innovation Edelio Bermejo said "The world needs innovative solutions to accelerate our shift towards renewable energy generation, distribution and storage – all areas in which Holcim can play a big part. With this collaboration, we are moving energy storage forward, opening up a new range of solutions based on materials that are local and recyclable."
Italy: Holcim has signed a collaboration agreement with energy company Eni for the development of ENI’s magnesium silicate-based carbon utilisation technology. The reaction of the magnesium silicate with captured CO2 emissions yields a product which Holcim hopes to use in its cement production.
Holcim Innovation Center head Edelio Bermejo said “Reaching net zero in cement manufacturing will require the deployment of carbon capture, utilisation and storage technologies at scale. ENI’s solution is very promising, and we are happy to explore its potential as it could take us all one step further on our decarbonisation journey.”
Switzerland: Holcim has partnered with Bloomberg Media to launch the Circular Cities Barometer, an exploration of best circular economy practices from cities around the world. The platform aims to improve understandings of how to empower cities to become more circular. The partners will publish the Circular Cities Barometer’s first findings at the Bloomberg Green Summit in April 2022.
CEO Jan Jenisch said “Circularity is the opportunity of our time. It unlocks economic growth in a way that is climate-friendly, nature-positive and socially inclusive. My vision for construction is to build more new from the old with recycled materials in every new building.”
RMIT University develops bubble column carbon capture method
19 January 2022Australia: RMIT University in Melbourne, Victoria, has developed a new method of carbon capture, called the bubble column method. The method uses liquid gallium at 100 – 120°C, through which flue gas is bubbled. This activates the CO2, leading to oxidation of the metal. The captured carbon accumulates on the surface of the pool.
Gallium is a by-product of bauxite and zinc ores mining. The United States Geological Service (USGS) has estimated its global reserves in these ores alone as 1Mt.
Project co-lead Torben Daeneke said “Turning CO2 into a solid avoids potential issues of leakage and locks it away securely and indefinitely. Because our process does not use very high temperatures, it would be feasible to power the reaction with renewable energy.” He added “Ideally the carbon we make could be turned into a value-added product, contributing to the circular economy and enabling the carbon capture and storage (CCS) technology to pay for itself over time.”
The Australian Government plans to invest US$719m in low emissions technologies by 2050 under its Net Zero Plan.
Spain: Cement Science Group (CemSciG) and the University of Málaga (UMA) have received a US$50,000 donation from US-based CSA Research for their research into reduced-CO2 cement production. The funding will continue the partners’ work at UMA’s department of inorganic chemistry, crystallography and minerology into alternative methods of cement production. Titles of their on-going projects include ‘Optimisation and Processing of LC3 Eco-Cements with Spanish Clays,’ ‘Microstructure Analyses of Limestone Calcined Clay Cements by Advanced Synchrotron Techniques’ and ‘Reduction of Cement Industry CO2 Emissions without Loss of Mechanical Properties.’
