Sublime Systems nears US$87m Department of Energy grant
26 March 2024US: Alternative cement developer Sublime Systems has entered award negotiations with the US Department of Energy for a grant worth up to US$87m. Gulf Oil & Gas News has reported that Sublime Systems plans to build an electrolysis-based cement plant in Holyoke, Massachusetts. The department’s Office of Clean Energy Demonstrations would provide any eventual funding under the Bipartisan Infrastructure Law and Inflation Reduction Act. Sublime Systems’ plant is one of 33 scalable decarbonisation solutions in energy-intensive industries selected for potential funding.
CEO Leah Ellis said “Access to sufficient capital for industrial-scale demonstrations is the single biggest obstacle preventing breakthrough innovations from reaching the scale humanity needs to combat the climate crisis. The Department of Energy has cleared this obstacle through funding from OCED’s Industrial Demonstrations Program, embracing its unique role in supporting the deployment of the decarbonised technologies of tomorrow. We look forward to collaborating with them on funding our first commercial manufacturing scale-up, which will ship our clean cement while creating meaningful economic opportunities for the surrounding community.”
Neocrete raises US$4m seed round for scaling and plant
26 March 2024New Zealand: Neocrete, a New Zealand start-up that decarbonises concrete production, has raised US$4m in seed funding. Wavemaker Partners, a Singapore-based venture capital firm, led the funding round with a 15% stake for US$2.7m. The funding also included contributions from five other investors, including NZ Green Investment Finance, which acquired a 3.8% share for US$700,000. Neocrete, founded in 2018, has developed an additive that can reduce the cement in concrete by 30-50% without loss in strength, increasing its durability.
Wavemaker Partners' managing partner Paul Santos said "Neocrete is designed to scale rapidly by using a cost-efficient production process that can leverage existing infrastructure."
Zarina Bazoeva, Neocrete co-founder and CEO, said that the funding will enable the company "to scale to meet initial global demand for Neocrete’s additive”. The company plans to complete setting up an Auckland manufacturing facility and scale up a research and development programme, "which is on track to produce cement-free, zero-carbon concrete by 2027,” according to Bazoeva.
US: Brimstone is negotiating a US$189m Federal award with the Department of Energy to finance the construction of a new decarbonised cement plant. This plant will produce up to 140,000t/yr of Ordinary Portland Cement and supplementary cementitious materials, reducing CO₂ emissions by 120,000t/yr.
Brimstone's process uses carbon-free calcium silicate rocks, reducing its CO₂ footprint. In July 2023, Brimstone's cement met ASTM C150 standards, confirming the effectiveness of its decarbonised process. The company is preparing to construct a pilot plant near Reno, Nevada.
Sweden: Researchers at Chalmers University of Technology, Sweden, have developed a method to simplify the construction of textile-reinforced concrete structures, a move that is expected to lead to more environmentally friendly infrastructure like bridges, tunnels, and buildings. The new technique addresses the high carbon footprint of cement.
This innovation, involving carbon fibre textiles as a replacement for steel reinforcement, enables lighter structures with reduced cement usage, thereby lowering the overall carbon impact. Karin Lundgren, Professor of Concrete Structures at Chalmers Department of Architecture said "A great deal of the concrete we use today has the function to act as a protective layer to prevent the steel reinforcement from corroding. If we can use textile reinforcement instead, we can reduce cement consumption and also use less concrete, thus reducing the climate impact."
The research is detailed in a paper titled 'Textile reinforced concrete members subjected to tension, bending, and in-plane loads: Experimental study and numerical analyses', which was published in the Construction and Building Materials journal. The study, a collaborative effort between Chalmers University and Gdansk University of Technology in Poland, is supported by the Swedish Research Council.
Switzerland: ABB and Captimise have enhanced their collaboration, focusing on advancing cost-effective carbon capture, utilisation, and storage (CCUS) technologies in the cement industry. Under a new Memorandum of Understanding, the partnership will develop various studies, including screening, feasibility, and FEED, aiding cement producers to identify efficient carbon capture solutions across their operations. The joint effort is expected to bolster the cement industry's efforts to meet its climate and net-zero targets.
CEO of Captimise, Mattias Jones, said “We draw on a track-record of more than 25 live case studies with CO₂ emitters across Europe and the US and know we’ll be able to support operations of all sizes in cement through combined CCUS, automation and electrification technologies.”
Global Business Unit Manager at ABB Process Industries, Max Tschurtschenthaler, said “Reducing the CO₂ emissions from cement manufacturing is a major challenge and a top priority for this industry. We are on a mission to make it more cost-effective. By combining our world-class automation, electrification and digital technologies with the know-how of partners like Captimise, we can further support the cement industry in achieving their climate and net zero targets.”
Cemsuisse urges CBAM adjustment for cement industry
25 March 2024Switzerland: The decision of the Swiss government in June 2023 against the implementation of a Carbon Border Adjustment Mechanism (CBAM) has been strongly criticised by the Swiss cement association, Cemsuisse. The association warns of a potential relocation of the Swiss cement industry without such a mechanism, referencing a report by Polynomics. This report concludes that a Swiss CBAM is necessary to level the playing field with EU and non-EU cement suppliers. The EU initiated a CBAM test phase in October 2023, aiming to mitigate production relocation risks to countries with less stringent environmental regulations.
The federal government concluded that a CBAM in Switzerland would benefit few emission-intensive industries at the expense of the wider economy, while also facing regulatory and trade policy risks. It plans to reassess the need for a CBAM in mid-2026, in line with the EU's interim CBAM report.
Cemsuisse, referencing the Polynomics report, states that waiting to potentially introduce a CBAM in Switzerland is not an option. Investments in carbon capture and storage (CCS) are deemed essential for Switzerland's net-zero climate goal and without a CBAM, there is a risk of these investments being unviable due to uncertainty over cost recovery.
The report also points to the risk of increased clinker imports from third countries into the EU, which would be processed and then exported to Switzerland without CBAM levies. As an example, Cemsuisse mentions a planned milling station in Ottmarsheim, Alsace. It says that without a CBAM, the production site in Switzerland faces serious threats.
Cemsuisse said “Without CBAM, this certainty is lacking. And without CCUS, long-term production in Switzerland won't be viable. The population has accepted the climate protection law last summer, where the net-zero goal is legally anchored."

Boliden announces upcoming alternative cement plant
22 March 2024Finland: Boliden says it has a developed a 95% reduced-CO2 alternative cement production process based on the use of slag. Nordic Daily News has reported that the process has received verification from ‘established players in the cement industry.’ A preliminary study is underway, wherein Boliden will establish a 250,000t/yr production plant. Additionally, the process extracts usable metal from slag.
UK: Capsol Technologies has been selected to conduct a study on its carbon capture technology at Aggregate Industries Cauldon cement plant in Staffordshire. Owned by the Holcim Group, the company’s plant will undergo a feasibility study by Capsol Technologies for its CapsolEoP® carbon capture system. The potential for carbon capture at this plant is 600,000t/yr of CO₂. The CO₂ captured will be stored geologically through the nearby MNZ Cluster or HyNet North West.
CCO Johan Jungholm said “CapsolEoP® provides a cost-efficient carbon capture solution for cement, and our solution can be run on electricity alone without expensive heat integration or external steam supply. It offers flexibility in the optimisation of the designs, allowing for high capture rates, high reliability and low energy consumption."
The contract includes supplier input for the feasibility study, and further pre-FEED engineering if Capsol's technology is selected. The UK Government's Industrial Energy Transformation Fund (IETF) is funding the study, with Petrofac as Aggregate Industries engineer. This study is part of Peak Cluster's objective to reduce over 3Mt/yr of CO₂ from cement, lime, and refuse facilities by 2030. Capsol Technologies is focusing on the cement industry, which accounts for about 8% of global CO₂ emissions.
