Spain: A consortium consisting of Cemex España, energy suppliers Enagás and Redexis, renewable power and infrastructure company Acciona and 30 other partners has commissioned Europe’s first solar power-to-green hydrogen plant at the site of Cemex España’s Lloseta cement plant on Majorca. The EU contributed Euro10m to the approximately Euro50m project. Euro3.75 million came from the Balearic Islands Autonomous Community government and Euro2.5m from the Spanish Institute for Energy Diversification and Saving (IDAE) of the Ministry of the Ecological Transition. The project will generate 300t/yr of hydrogen, eradicating 20,700t/yr of CO₂. The hydrogen will primarily fuel city buses in Palma, as well as air conditioning units in public and private buildings there.

China: Geely will include electric cement truck battery pack change facilities in its roll out of 5000 vehicle battery change stations across China. Carscoops News has reported that the stations will be able to remove vehicles’ 3.2t, 280kWh battery packs in five minutes and fully recharge them in an hour. Cement truck drivers will be able to access the service via a simple QR code scan.

Indonesia: Entsorga has dispatched two Spider bridge cranes and two Pelican feeding and dosing systems for the construction of two new solid recovered fuel (SRF) storage, feeding and dosing systems at Indocement Tunggal Prakarsa’s 11.9Mt/yr Citeureup cement plant in Bogor Regency. The systems will have a total capacity of 50t/hr. An advanced supervision system will monitor and control their 24-hour operation. The Italy-based supplier says that both lines are highly automated and will reduce both CO₂ emissions and fuel consumption.

CEO Francesco Galanzino “The systems will help the cement plant to maintain its 2030 sustainability commitments, in line with the policies of HeidelbergCement who is a real first mover in the path toward sustainability. Such project it is a very important step in a Country where environmental policies are in their early stage.”

Saudi Arabia: Al Kifah Ready-Mix & Blocks (KRB) has announced the upcoming launch of its ConGreen reduced-CO₂ concrete products range at the Big 5 Saudi construction summit on 28 – 31 March 2022. ConGreen concretes replace clinker with lower-carbon materials such as pozzolan and use Canada-based Carbon Cure Technologies’ embedded recycled CO₂ technology to reduce its carbon footprint by up to 30% compared to conventional ordinary Portland cement (OPC) concretes. In addition to this, KRB says that ConGreen concretes also provide improved workability and pumpability properties, as well as being highly durable, with high passing and finishability. They have very low rapid chloride permeability (RCP), water absorption and water permeability properties and low heat of hydration.

General Manager Nigel Harries said “We are committed to driving energy efficiency and addressing the global emission challenges. We aim to help build a better community and environment-friendly facilities by producing high-quality concrete, such as ConGreen, that has a reduced environmental impact and is characterised by its high performance, durability and sustainability, with a low carbon footprint as compared with standard concrete.”

Spain: FYM will host 350 pupils from Malaga's primary schools on its Feet on the Ground sustainability awareness initiative. The initiative consists of using digital resources and fieldwork to explore Malaga's biodiversity. It will highlight the work of HeidelbergCement's Spanish quarry restoration partner Tormes Foundation. FYM said that the initiative is part of its strategy to improve quality of life and the environment in areas where it operates, informed by transparency and dialogue with host communities.

New Zealand: Golden Bay Cement has obtained two hydrogen-fuelled cement trucks produced by Hyzon. TR Group leased the vehicles to the cement company.

Golden Bay Cement said “These two zero emission green trucks signal the future, and are just another step we take to a smaller carbon footprint across our business.”

Switzerland: Vigier Ciment is operating a self-charging electric dump truck at its limestone and marl quarry in Biel. The 45t truck’s regenerative braking system recharges its 600kwh lithium battery on the downhill trip from the quarry to the primary crusher. Its 65t capacity more than doubles its weight when laden, easily enabling it to recover charge for the return trip. Each trip generates an estimated 10kwh of surplus energy. In ordinary use, this would equate to 77Mwh/yr. It saves 50,000 – 100,000l/yr of diesel and eliminates an estimated 196t/yr of CO₂. Green Car Reports has reported that Kuhn Schweiz built the dump truck, based on Japan-based Komatsu’s HB model truck. It is the world’s largest electric vehicle.

Benelux/France: Cementir Holding has introduced its Futurecem limestone calcined clay cement into the Benelux and French cement markets. Futurecem cement applies Cementir Holding’s patented processes to substitute over 35% of clinker in cement with limestone and calcined clay, preserving the cement’s strength and quality while reducing its carbon footprint by 30% compared to ordinary Portland cement (OPC).

Cementir Holding previously rolled out Futurecem cement in Denmark in 2021. In 2022, it plans to launch InBind high performance concrete (HPC) and ReCover ultra-high performance concrete (UHPC) to expand its range of HPC and UHPCs using Futurecem technology.

Eddy Fostier, managing director of Cementir Holding’s Belgian subsidiary CCB, said “Thanks to the joint efforts of the group and CCB teams, Futurecem technology is the main pillar for CCB’s low carbon transition within the Group roadmap. This product technology is matching customer needs, highlighted through a specific survey carried out across the most relevant market areas and applications.” Fostier concluded “I’m fully convinced that Futurecem will play a relevant role in the decarbonisation of the construction industry, where cement and concrete are essential building materials both in the present and in the future.”

US: Titan America’s Essex cement distribution facility at the Port of Newark, New Jersey, has made its first dispatches of Type IL Portland limestone cement (PLC) to New Jersey and the New York Metropolitan Area. The producer said that the Essex terminal is due to complete its transition to 100% reduced-CO₂ cement dispatches in 2022. Titan America says that it is the leading supplier of Type IL PLC on the US domestic market.

Sales Manager Joe Tedesco said “We see an increase in demand as infrastructure money is budgeted by transportation agencies requiring construction with the use of lower-carbon cement.”

US: 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.
