Votorantim Cimentos Europe, Asia and Africa CEO Jorge Wagner said "We need agility with the administration, because the investments are stratospheric and long-term. We want to obtain subsidies, taking advantage of European funds." He concluded "We have the opportunity to carry out a very beautiful project in Andalusia and beat the Americans."
Holcim and TotalEnergies to work together on decarbonising upgrade to Obourg cement plant in Belgium
05 October 2022Belgium: Holcim and TotalEnergies have signed a memorandum of understanding (MOU) to work towards the full decarbonisation of the Obourg cement plant. Various energies and technologies will be assessed for the capture, utilisation and sequestration (CCUS) of around 1.3Mt/yr of CO2 emitted by the unit. The project will include working towards building an oxyfuel switchable kiln as part of an upgrade project at the plant and the transportation and use of the captured CO2 by TotalEnergies for a synthetic fuel producing scheme and/or deposit in geological storage in the North Sea.
TotalEnergies will also assess the development of renewable projects to power a new electrolyser, which would generate the green hydrogen needed to produce synthetic fuels. This new renewable energy production capacity would also power Holcim’s new oxyfuel kiln. Finally, the oxygen emitted by the electrolyser would be used to fuel the new kiln.
Bart Daneels, the chief executive officer of Holcim Belgium said “Cement industry decarbonisation is extremely challenging because of the process's inevitable CO2 emissions, which put us firmly in the hard-to-abate sector. CCUS is vital for Obourg to become the first net carbon neutral clinker plant in northwest Europe. We are very happy to work with TotalEnergies to accelerate the development of these CCUS solutions for GO4ZERO. By joining the first movers, we want to set the standards for future clinker manufacturing plants.”

Titan Cement Group’s H2CEM green hydrogen project included in EU Hy2Use initiative
27 September 2022Greece: Titan Cement Group says that its H2CEM green hydrogen projection has received inclusion under the EU Important Project of Common European Interest (IPCEI) Hy2Use. Hy2Use consolidates funding for hydrogen electrolysis, transport and storage development projects across Europe. Titan Cement Group’s H2CEM project consists of Euro60m-worth of new green hydrogen production installations at its Drepano, Efkarpia and Kamari cement plants. The installations will produce hydrogen through electrolysis using renewable energy sources. The producer says that use of the hydrogen as cement fuel will reduce the plants’ CO2 emissions per tonne of cement by 8%, corresponding to 160,000t/yr of emissions. H2CEM is Hy2Use’s only cement plant project.
Titan Cement Group aims to achieve carbon neutrality by 2050.
Europe: The European Commission has approved the IPCEI Hy2Use plan for the construction of an international hydrogen electrolysis, transport and storage network. IPCEI Hy2Use consists of multiple projects planned for completion by 2026, with the commissioning of all infrastructure scheduled for 2036. 13 EU member states and Norway will contribute Euro5.2bn in funding, with a view to attracting private investments worth Euro7bn.
Holcim Belgium joins Fluxys CO2 transport network
21 September 2022Belgium: Holcim Belgium has joined Fluxys open-access CO2 transport network project. It intends to use the Fluxys network to either transport captured CO2 for sequestration in the North Sea or reuse in other industry after it builds a new 6000t/day production line at its Obourg plant by early 2026. As part of this process Holcim Belgium also plans to build a cryogenic CO2 capture and treatment unit at Obourg by early 2028.
Pascal De Buck, the chief executive officer of Fluxys, said "Holcim's interest in our CO2 network project at the Mons industrial cluster confirms the efforts industries are making to find solutions for decarbonising their activities. We're here to meet that need, which is why we offer them an open-access CO2 network they can use to transport their captured CO2 to storage or reuse sites. This kind of network helps achieve climate objectives and contributes to the long-term viability of the economy."
The proposed Fluxys CO2 transport network will see the construction and creation in Belgium of pipelines, intermodal hubs, port terminals and shipping from 2025 onwards. The proposed infrastructure is intended to transport three gases: CO2, hydrogen and methane.
Update on hydrogen injection in cement plants
14 September 2022Argos Honduras revealed this week that it has been testing the injection of hydrogen into the kiln of its integrated Piedras Azules cement plant. It has completed a pilot with Portugal-based company UTIS. As part of the process it has been trialling, it has split water by electrolysis and then injected the hydrogen and oxygen directly into the kiln via the main burner. The pilot has reportedly increased clinker production and reduced petcoke consumption at the plant.
Argos is far from alone in using hydrogen in this way. At the end of August 2022 Cemex said that it was also starting to use hydrogen at its San Pedro de Macorís cement plant in the Dominican Republic. CRH UK-subsidiary Tarmac completed a trial in July 2022 using hydrogen as an alternative to natural gas at its Tunstead lime plant. HeidelbergCement UK-subsidiary Hanson also ran a successful trial using hydrogen as part of the fuel mix at its Ribblesdale cement plant in 2021. The government-funded trial used a combination of hydrogen (39%), meat and bone meal (12%) and glycerine (49%) to reach a 100% alternative fuels substitution rate. In 2021 Hanson reported that fuel switching to hydrogen could help it reduce its 2050 CO2 emissions by about 3%, or by -35kg CO2/t of cement product.
Cemex appears to be a leader in using hydrogen in this way. The Mexico-based company started injecting hydrogen in 2019 and retrofitted all of its European cement plants with the technology to do so in 2020. It then said it wanted to roll this out to the rest of its operations. The project in the Dominican Republic is an example of this. In February 2022 it announced an investment in HiiROC, a UK-based company that has developed a method using thermal plasma electrolysis to convert biomethane, flare gas, or natural gas into hydrogen. The stated aim of this investment was to increase Cemex's hydrogen injection capacity in its cement kilns and to increase its alternative fuel substitution rate. Back in 2020 Cemex said that it planned to use hydrogen injection to contribute 5% of its progress towards its 2030 CO2 emissions reduction target along with other measures such as increasing its thermal substitution rate and reducing its clinker factor.
As can be seen above there are a number of examples of hydrogen injection being used in cement plants in Europe and the Americas. However, there is very little actual data available publicly at this stage on how much hydrogen that the plants are actually using. For example, Cemex may have hydrogen injection equipment installed at all of its plants in Europe but it is unclear how many plants are actually using it. This is understandable though, given how commercially sensitive the fuel mix of a cement plant is and in Cemex’s case if it wishes to maintain a leader’s advantage in using a new technology.
It is interesting to see, in what has been released so far, the focus on doing deals with companies that supply electrolysis technology such as HiiROC and UTIS. A feasibility study ahead of the Hanson trial at Ribblesdale by the MPA, Cinar and the VDZ suggested that upgrading a kiln burner and adding all the necessary hydrogen storage and pipework could cost at least Euro400,000. However, this study also pointed out that the cost of hydrogen made a big difference to the cost of the CO2 saving from using it as an alternative fuel. Hence the focus on the technology partners. It will be interesting to see how many more hydrogen injection projects are announced in the coming months and years and, crucially, who is providing the technology to supply the hydrogen.
Honduras: Argos Honduras is set to start a new hydrogen injection process at its integrated Piedras Azules cement plant. During the process, water molecules are split using electricity into hydrogen and oxygen and then injected into the kiln through the main burner. The main objective of this technology is to reduce the use of fossil fuels, CO₂ emissions levels and energy consumption at the plant.
Luis Eduardo Tovar, the manager of Argos Honduras, said “We are proud to be committed to innovation and new technologies that allow us to keep our operation at the forefront of the industry. This project has allowed us to reduce our C0₂ emissions and optimise our processes to become increasingly efficient."
A pilot was previously conducted in conjunction with Portugal-based UTIS. It showed that by using the technology the plant could increase its clinker production and reduce petcoke consumption.
Dominican Republic: Cemex says it is planning to start using hydrogen technology at its integrated San Pedro De Macoris cement plant. It inaugurated the project during a visit by chief executive officer Fernando A Gonzalez. It is part of the company's Future in Action program that seeks to achieve carbon neutrality by 2050.
The group currently uses the technology by injecting hydrogen into cement plant kilns to optimise the combustion process and to increase the use of alternative fuels. It ran a trial at its Alicante cement plant in Spain using hydrogen in 2019 and says it rolled the process out to all of its European cement plants in 2021. Other hydrogen-based projects the cement producer is working on include a partnership with Hiiroc, a gas-to-hydrogen plant producer, and the creation of a renewable hydrogen industrial plant in Spain in collaboration with Acciona and Enagas.
