Quinn Building Products reports on Covid-19 response
15 July 2020Ireland/UK: Quinn Building Products has said that rigid social distancing and sanitation practices introduced in response to the coronavirus in March 2020 have become the ‘new normal’ for its 800 employees across nine sites. The measures include: 22-person-capacity socially distanced team meeting areas, overflow break and lunch marquees; 24/7 cleaning services from AAA Pristine Clean; and socially distanced floor marking and directional signage.
The company said, “Our dedicated teams have done an outstanding job on designing and implementing these changes and their work has allowed us to reopen all of our production facilities in past weeks. We are also working with all our customers, contractors and suppliers to ensure we can safely service customer needs.”
UK: Mexico-based Cemex has confirmed its decision to mothball the 0.8Mt/yr integrated South Ferriby, Lincolnshire cement plant following a consultation period with employee and union representatives. The company estimates that the majority of redundancies of the plant’s 110 staff will happen in July 2020.
It said, “Cemex customers will be supplied from the company’s existing cement network. Cemex’s supply chain plan and commercial management will ensure that customer service will be maintained at all times. Cemex remains committed to the UK and will continue to have a strong national presence.”
Vicat to implement Carbon8 Systems carbon capture and use system at Montalieu cement plant
10 July 2020France: UK-based Carbon8 Systems has announced plans for the commercial implementation of its carbon capture and use (CCU) system at Vicat’s Montalieu integrated cement plant in France. It follows successful demonstration projects at cement plants in the UK and Canada.
The company’s CO2ntainer product will be deployed directly onsite at the plant and integrated into Vicat's existing industrial processes. It will capture CO2 directly from the plant's flue gas emissions and use this as part of its Accelerated Carbonisation Technology (ACT) process. This accelerates the carbonation of cement bypass dust into lightweight aggregates. In its first phase of operation it will process and convert up to 12,000t of cement bypass dust.
Green hydrogen for grey cement
08 July 2020Hydrogen 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.
UK: Germany-based Loesche has joined a network of expert companies that “share relevant information and results regarding the reduction of environmental impact and the use of coal and enhanced energy security globally” in becoming an IEA Clean Coal Centre knowledge partner. The company said, “We are excited to be part of this renowned group of companies that aim to improve the environmental impact by use of green technologies, renewable resources, and alternative use of energy sources for more sustainable engineering projects.”
HeidelbergCement’s asset portfolio revalued
07 July 2020Germany: Following a comprehensive review of its assets HeidelbergCement has announced a Euro3.4bn impairment to its company value compared to the figure from a precious valuation prior to the second quarter of 2020. The company gave the reasons for the impairment as: the demand impacts of the coronavirus pandemic; economic effects on operations in individual countries; notably in the UK post-Brexit; and an increase in the market risk premium used by the Institut für Wirtschaftsprüfer (German public auditing body) for valuation to 7% from 6%. The largest regional impairment was Euro2.7bn, in Western and Southern Europe. Euro2.3bn of the total impairment, “relates to the Hanson acquisition” by HeidelbergCement in 2007.
UK: The Global Cement and Concrete Research Network (Innovandi) has launched a week of online workshops dedicated to lowering cement and concrete’s carbon footprint through research and development, with the participation of 30 companies and 40 scientific institutions.
