Tarmac’s Tunstead lime kiln uses hydrogen fuel
01 July 2022UK: Tarmac has successfully produced lime at its Tunstead, Derbyshire, plant using net zero hydrogen to fuel its kiln. The achievement was the culmination of a series of trials substituting various proportions of hydrogen for natural gas.
Tarmac’s lime director Graham Cooper said “Lime has been manufactured in the Peak District for centuries and this forward-thinking project aims to ensure the future of this nationally significant industry as the UK transitions to net zero.”
Australia: Adbri is part of a consortium of eight Australian industrial manufacturers, developers and port operators collaborating with AGL Energy on a feasibility study for a green hydrogen plant at the site of the latter’s Torrens Island power plant in South Australia. AFR Online News has reported that any future hydrogen plant established by the partners would rely on solar and wind power, which has large potential in the region.
The South Australian government previously launched its first US$414m green hydrogen project in Whyalla in March 2022.
Chile: Melón has inaugurated a new 0.25Mt/yr grinding plant in Punta Arenas. The project had an investment of US$45m, according to the El Pingüino newspaper. In its first year of operation an output of 80,000t is planned. It is the first cement plant in the Magallanes Region. Spain-based Cemengal supplied a Plug&Grind Xtreme grinding unit for the project.
Jorge Eugenín, the chief executive officer of Cementos Melón, attended the event and said, “For us Magallanes has always been an interesting market. Its consumption is comparable to cities in developed countries.” He added that the region has a per capita cement consumption level of 550kg/yr compared to the Chilean mean of 280kg/yr.
The cement producer previously announced plans to double the production of the plant by building a second grinding mill if the market supported it. Eugenín commented that the announcement of a large-scale hydrogen project in the region by Total Eren in late 2021 could add further momentum to expansion plans for the new cement plant.
Austria: The Austrian Cement Industry Association (VÖZ) has launched a roadmap for carbon neutrality by 2050. The initiative follows the 5C approach of Clinker, Cement, Concrete, Construction and Carbonation as prompted by the European Cement Association, Cembureau. Selected targets from the document include reducing the sector’s average clinker factor to 52% by 2040 from 70% in 2020, using carbon-neutral electricity from 2030 and meeting a recycling rate for concrete and demolition waste of 25% in 2050 from 10% in 2022. Sebastian Spaun, the managing director of VÖZ, highlighted the ‘Carbon2ProductAustria’ (C2PAT) initiative as a key project where capture CO2 from Lafarge Zementwerke’s Mannersdorf cement plant will be used with hydrogen to produce synthetic fuels, plastics or other chemicals.
Hanson UK signs agreement with Shell on working towards net zero in the construction industry
13 May 2022UK: Hanson has signed a memorandum of understanding with Shell to work together to explore opportunities that help the construction industry’s transition to net zero emissions.
Under the agreement the companies plan to explore: using hydrogen for transport and industrial processes; using capture utilisation and storage (CCUS) in cement production; looking at lower carbon fuels and electric vehicles; digital innovations in energy production, consumption and efficiency; improving bitumen and asphalt technology; and renewable energy sources such as solar installations and batteries to replace diesel generators. In addition, the companies say they will consider the possibility of collaborating in future business opportunities or new business models, which will create value and scope for further decarbonisation.
Hanson’s chief executive officer Simon Willis said, “We are already working together on several initiatives to decarbonise asphalt with bitumen materials and innovations which promote long life, increased use of recycled materials, low carbon products and the circular economy.” He added that “Hanson and Shell have a long-established working relationship and are committed to sharing knowledge and resources to jointly work on projects that will facilitate our transition to net zero emissions.”
Germany: Mexico-based Cemex has joined a consortium with Sasol EcoFT and Enertrag that plans to use CO2 and hydrogen to produce aviation fuel. The project is part of Cemex’s Future in Action program and is part of its plan to develop a carbon neutral operation at its Rüdersdorf cement plant by 2030. The consortium will source green hydrogen generated from wind and solar energy from Enertrag. The CO2 will come from the Rüdersdorf cement plant, which will provide 100t/day CO2 in the project’s initial stages. Sasol will then contribute its technology to produce e-kerosene, which, once certified, can be blended to constitute up to 50% of jet fuel.
The Rüdersdorf carbon neutral alliance includes over 20 start-ups, universities, companies from other industries and authorities working to develop industrial-scale solutions achieve the first carbon-neutral cement plant in the world.
Enertrag is a renewable-energy company based in Brandenburg. It operates utility-scale integrated energy plants in 10 countries. Its plants produce electricity and green hydrogen from wind and solar sources.
Sasol EcoFT is part of Sasol Group. It uses its technology to produce sustainable fuels and chemicals from green hydrogen and sustainable carbon sources, via the Power-to-Liquids process.
HeidelbergCement, Felleskjøpet AGRI and Egil Ulvan Rederi to build the world's first zero-emission bulk carrier
06 April 2022Norway: HeidelbergCement, agricultural cooperative Felleskjøpet AGRI and shipping company Egil Ulvan Rederi plan to build what they say will be the world's first zero-emission bulk carrier. The project has also received support of around Euro12m from the Norwegian government-owned sustainability company Enova. The vessel is scheduled for completion and commissioning in 2024. Once operational the ship will be used to transport aggregates products for HeidelbergCement and grain for Felleskjøpet between west Norway and east Norway using hydrogen powered transport.
Egil Ulvan Rederi was selected following a tendering process in 2021. The ship is intended to be highly energy efficient, using rotor sails and has a streamlined design to reduce energy consumption. It will be powered by hydrogen from Norwegian energy supplier Statkraft but will also have small auxiliary batteries and a fuel cell on board to maximize flexibility.
Giv Brantenberg, general manager HeidelbergCement Northern Europe, said “The project addresses emissions from the transport part of our value chain. It is unique, ambitious and future-orientated. It is fully in line with HeidelbergCement Group's target to be the leading actor in our industry on the path to carbon neutrality." HeidelbergCement estimates that the carbon footprint of the aggregates products can be reduced by 50 - 60% by using the zero emission vessel, as transport accounts for a significant part of the total carbon footprint of these products.
