Spain: Cemex España reopened its Lloseta cement plant in Majorca in mid-April 2021. The unit will start by operating at a low production level until demand levels build, according to the El País newspaper. The plant intends to use alternative fuels such as biomass to reduce its CO₂ emissions. It is also working with the Power to Green Hydrogen Mallorca project to use ‘green’ hydrogen created partly using solar energy. The plant now employs 20 people, compared to 96 before its closure in January 2019.

Germany: Mexico-based Cemex subsidiary Cemex Zement has set up an innovation acceleration partnership called Carbon Neutral Alliance to support its work to achieve net zero CO₂ emissions at its Rüdersdorf cement plant by 2030. The association will work to develop industrial-scale demonstration projects in line with the company’s Future in Action programme. Its scope will include carbon capture and storage (CCS), the transformation of captured CO₂ into building materials, synthetic fuels and green hydrocarbons, hydrogen production and waste heat recovery (WHR). Cemex plans to share the knowledge gained by the alliance across its global cement network.

Managing director and Rüdersdorf plant manager Stefan Schmorleiz said, "It is expected that CO₂ will be further processed to convert to new forms of energy and materials for use locally by industrial, residential, and transport sectors. Together with our partners, we will take feasibility studies through to economic solutions to decarbonising cement production.”

Spain: Mexico-based Cemex subsidiary Cemex España has announced plans to resume activity at its Lloseta cement plant in Majorca at a limited production level. The UltimaHora newspaper has reported that the company will employ the staff who stayed on for maintenance purposes from the plant’s January 2019 closure. After suspending activity at the plant the company had until mid-April 2021 to inform the local government of its plans for the site.

Cemex is in the process of establishing a green hydrogen plant at Lloseta with a Euro10m EU grant. It said, "We do not rule out that in the future the cement plant may adapt and become an industrial benchmark in the use of green hydrogen for the production of cement with a low carbon footprint."

UK: HeidelbergCement subsidiary Hanson has partnered with the Hynet North West consortium for a study on carbon capture and storage (CCS) solution at its Padeswood, Flintshire, cement plant. The consortium is planning to implement carbon capture and storage installations at industrial facilities across Flintshire, Wrexham, Cheshire, Merseyside, Greater Manchester and Lancashire. It says that when active the network will constitute the world’s first low carbon industrial cluster, with a total reduction of 10Mt/yr of emissions by CCS. The Padeswood plant would account for 800,000t/yr of this total.

Hanson group chief executive officer Simon Willis said, “Our involvement in the HyNet North West project is the latest example of our commitment to cutting CO₂ emissions. CCS at our cement plants will be a key part of our roadmap to achieve net zero carbon by 2050. The first step would be for us to carry out a feasibility study - this would give us a clear design basis and cost estimate for a capture plant and connection to the planned HyNet North West CO₂ network and storage system.”

The HyNet North West project also includes production, storage and distribution of low carbon hydrogen, which will help to decarbonise other industries whose CO₂ emissions primarily come from fossil fuels. The project, led by Progressive Energy, is being developed by a consortium of regionally located partners including Cadent, CF Fertilisers, Eni UK, Essar, INOVYN and the University of Chester as well as Hanson.

Mexico: Cemex plans to start using hydrogen as part of its fuel mix at its cement plants around the world in 2021. The estimated cost of the roll-out is US$40m. The company says it completed the deployment of its hydrogen technology across all of its cement plants in Europe in 2020 following trials at the Alicante Cement Plant in Spain in mid- 2019.

Global operations, technical and energy vice-president Roberto Ponguta said, “The fast adoption of this new hydrogen-based technology is a clear example of Cemex's innovation efforts and its strong commitment to decarbonise the cement production process.” He added, "We continue to identify and deploy existing technologies which have a high potential to contribute to our sustainability goals, and hydrogen is a key lever.”

UK: HeidelbergCement subsidiary Hanson has installed a solar and wind-powered hydrogen generation demonstration unit at its Port Talbot Regen ground granulated blast furnace slag (GGBFS) plant in Port Talbot in Neath Port Talbot. The company says that the project is part of a collaboration with Swansea University’s Energy Safety Research Institute under the European Research and Development Fund’s Reducing Industrial Carbon Emissions initiative. The hydrogen generated by the installation will replace natural gas in the GGBFS plant’s burners.

Head of sustainability Marian Garfield said, “It is estimated that cement is the source of just under 2% of UK CO₂ emissions. With demand for cement and cement replacement products predicted to increase by 25% by 2030, researchers and industry are working hard to reduce the level of CO₂ emissions associated with production. As a leading manufacturer, we take our responsibility very seriously. In the UK we have already achieved a 30% reduction in CO₂ emissions since 1990 across the business and have set an ambitious new target of a 50% reduction by 2030 from the same baseline. We are constantly looking to improve energy efficiency and carbon reduction at our cement and Regen GGBFS plants, so we are delighted to be involved with this innovative research project.”

France: Vicat has joined US-based Schlumberger New Energy, clean energy specialist CEA, Vinci Construction and the Occitan Regional Agency of Energy and Climate (AREC) in a hydrogen production technology joint venture called Genvia. The partnership will establish a ‘gigafactory’ at which to develop high-temperature reversible solid oxide electrolyser technology. The gigafactory will be situated in Béziers, Occitan. Deployment will take place via CEA’s Grenoble, Auvergne-Rhône-Alpes site.

“We are very pleased to be working alongside such experienced and strong partners as we strive to develop technologies that enable decarbonisation,” said François Jacq, chairman of the CEA. “Together, building on a set of technologies developed by the CEA over the last decade, we have ambitious growth plans for a technology that we expect to be a game-changer in the production of clean hydrogen. This initiative demonstrates an alignment of environmental and economic growth ambitions that is important for France and Europe in support of the government's and the commission's recovery plan.”

The technology Genvia plans to use is intended to achieve a high system efficiency, resulting in less electricity use per kg of hydrogen produced. The venture says that the technology is the first of its kind that is fully reversible, giving it the flexibility to switch between electrolysis and fuel cell functions.

Belgium: Carmeuse has signed a joint development agreement with France-based energy transition specialist ENGIE and John Cockerill for a carbon capture and utilisation (CCU) project in Wallonia. It will concentrate CO₂ from a new type of lime kiln and combine it with ‘green’ hydrogen to produce ‘e-methane.’ The hydrogen will be produced by a 75MW electrolyser plant powered by renewable electricity. The company said, “The produced e-methane will be suitable for injection into the national natural gas grid. This renewable e-methane can be used by industrial users or as an alternative fuel in the transport sector, thus allowing these sectors to decarbonise.”

Construction is due to begin in 2022 for commissioning of the installation in 2025. Its total investment cost is Euro150m. The partners have applied for funding from the EU Innovation Fund and Important Project of Common European Interest (IPCEI) fund. The project’s estimated CO₂ emissions reduction over 10 years is 900,000t

Chief executive officer (CEO) Rodolphe Collinet said, “We are delighted to join forces with John Cockerill and ENGIE for the development of this very exciting and strategic project. It is a major step forward in our ambition to become CO₂-neutral by 2050. This project is a very concrete and important example of Carmeuse’s strong commitment and contribution to sustainable development.”

Germany: The Westküste100 green hydrogen project has received funding approval from the Federal Ministry of Economic Affairs. The plan is backed by an investment of Euro89m, with Euro30m of this total approved for the project’s launch in August 2020. The initiative intends to produce green hydrogen, transport it in the gas network, use it in industrial processes and to interlink different material cycles within the existing infrastructure. The consortium brings together ten partners: EDF Deutschland, Holcim Deutschland, OGE, Ørsted Deutschland, Raffinerie Heide, Heide’s municipal utility, Thüga and ThyssenKrupp Industrial Solutions, along with the Region Heide development agency and the Westküste University of Applied Sciences.

“An electrolysis plant with a capacity of 700MW - this is our vision and the next milestone in implementing the development targets laid down in the national hydrogen strategy by 2030,” said Jürgen Wollschläger, managing director of Raffinerie Heide and coordinator of the Westküste100 project.

The funding approval enables work to begin on the first phase of the project, which is set to run for five years. A newly formed joint venture, H2 Westküste, comprising EDF Deutschland, Ørsted and Raffinerie Heide, is to build a 30MW electrolyser which will produce green hydrogen from offshore wind energy and provide information on the operation, maintenance, control and grid compatibility of the equipment.

In a later stage of the project hydrogen from both electrolysis and CO₂ from a cement plant in Schleswig-Holstein will be used in the process. During the initial phase of the Westküste100 project preparations will be made for converting the Lägerdorf cement plant to an oxyfuel combustion process.

Thorsten Hahn, chief executive officer (CEO) and chairman of Holcim (Deutschland) said, “For us, as a manufacturer of building materials, the funding approval is a key milestone on the way to decarbonising cement production. Now all of us involved in Westküste100 must move forward quickly, decisively and dynamically in order to achieve our ultimate goal of cross-sectoral coupling on a large industrial scale in the coming years.”

Hydrogen and its use in cement production has been adding a dash of colour to the industry news in recent weeks. Last week, Lafarge Zementwerke, OMV, Verbund and Borealis signed a memorandum of understanding (MOU) to plan and build a full-scale unit at a cement plant in Austria to capture CO₂ and process it with hydrogen into synthetic fuels, plastics or other chemicals. This week, Air Products and ThyssenKrupp Uhde Chlorine Engineers (TUCE) signed a strategic agreement to work together in ‘key regions’ to develop projects supplying green hydrogen. Both of these developments follow the awarding of UK government funding in February 2020 to support a pilot project into studying a mix of hydrogen and biomass fuels at Hanson Cement’s Ribblesdale integrated plant.

As the title of this column suggests there is an environmental colour code to describe how hydrogen is made for industrial use. This is a bit more codified than when grey cement gets called ‘green’ but it pays to remember what the energy source is. So-called ‘green’ hydrogen is produced by the electrolysis of water using renewable energy sources such as hydroelectric or solar, ‘Grey’ hydrogen is made from steam reforming using fossil fuels and ‘Blue’ hydrogen is similar to grey but has the CO₂ emissions from the fuels captured and stored/utilised. Price is seen as the main obstacle to wider uptake of hydrogen usage as a fuel in industry although this is changing as CO₂ pricing mounts in some jurisdictions and the connected supply chain is developed. A study by BloombergNEF from March 2020 forecasted that green hydrogen prices could become cheaper than natural gas by 2050 in Brazil, China, India, Germany and Scandinavia but it conceded that many barriers would have to be overcome to get there. For example, hydrogen has to be manufactured making it more expensive than fossil fuels without government policy support and its, “lower energy density also makes it more expensive to handle.”

The three recent examples with respect to the cement industry are interesting because they are all exploring different directions. The Lafarge partnership in Austria wants to use hydrogen to aid the utilisation side of its carbon capture at a cement plant. The industrial suppliers, meanwhile, are positioning themselves in the equipment space for the technology required to use hydrogen on industrial plants. Secondly, ThyssenKrupp has alkaline water electrolysis technology that it says it has used at over 600 projects and electrochemical plants worldwide. Air Products works with industrial gas production, storage and handling.

Finally, the Hanson project in the UK will actually look at using hydrogen as a partial replacement for natural gas in the kiln combustion system. A Cembureau position paper in mid-2019 identified that the challenges to explore in using hydrogen in cement production included seeing how its use might affect the physical aspects of the kiln system, the fuel mass flows, temperature profile, heat transfer and the safety considerations for the plant. Later that year a feasibility study by the Mineral Products Association (MPA), Verein Deutscher Zementwerke (VDZ) and Cinar for the UK government department that is funding the Hanson project concluded that a hydrogen flame’s high heat in a burner alone might not make it suitable for clinker formation. However, the study did think that it could be used with biomass to address some of that alternative fuel’s “calorific limitations” at high levels. Hence the demonstration of a mixture of both hydrogen and biomass.

That’s all on hydrogen but, finally, if you didn’t log into yesterday’s Virtual Global CemProducer 2 Conference you missed a treat. One highlight was consultant John Kline’s presentation on using drones to inspect refractory in some hard to reach places. Flying a camera straight into a (cool) pyro-processing line was reminiscent of a science fiction film! Global Cement has encountered the deployment of unmanned aerial vehicles in quarry and stockpile surveys previously but this was a step beyond.
