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.

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.”

Germany: 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.

Global Cement and Concrete Association cement director Claude Loréa said, “Cement is fundamentally important to our world today and will play a crucial role in building the sustainable world of tomorrow. It is therefore critical to support and accelerate the breakthrough processes and products that will improve sustainability and decrease carbon emissions. The Innovandi Kick-off Week offers a platform for leaders from across the world of cement and concrete to collaborate with academic institutions and define the cutting-edge research that will address these challenges and help us create a better future.”

UK/Germany: The World Green Building Council has announced that HeidelbergCement is an official partner of its Europe Regional Network. HeidelbergCement joins 4500 other companies across Europe in supporting the regional network’s work towards networking leaders, raising awareness, proposing policy and providing assessment, certification and information.

HeidelbergCement chair Dominik von Achten said, “Together with the Europe Regional Network of the World Green Building Council, we now want to further intensify the promotion of sustainability and innovation in the construction sector. In this way, we are accelerating the development towards a carbon-neutral construction industry, and ultimately towards a carbon-neutral society in Europe.”

UK: Cemex has joined the Aldersgate Group alliance of companies in calling on the UK government to support an economic recovery, “aligned with the UK’s climate and environmental goal.” In a policy briefing, the Aldersgate Group said that a low-carbon recovery plan should: address regional inequality and unemployment; strengthen the UK’s economic competitiveness and productivity through investment in the sectors and technologies of the future; deliver critical public goods including clean air, better health and improved resilience to future environmental shocks; build a more resilient financial system fit to withstand future climate shocks ;deliver the Global Britain agenda by strengthening the UK government’s influence ahead of the G7 and COP26 summits that it will be hosting in 2021; and enable UK businesses to be competitive providers of low carbon goods and services.

Cemex Europe director of public affairs Martin Casey said, “Our aim is to enable the development of climate-smart urban projects, sustainable buildings and climate-resilient infrastructures. Setting a clear policy direction for restarting the economy will enable to play its part in the recovery in a way that advances our climate and environmental goals.”

UK: Tarmac says that it is the first cement company to have signed up to the EV100, a scheme that targets net-zero carbon emissions in transportation. Under the initiative, Tarmac will replace its fleet of 2000 corporate cars and vans with electric models by 2030.

Tarmac procurement director Jonathan Harry said, “We are fully committed to supporting the UK’s ambition of net-zero carbon emissions by 2050 and have been proactive in making significant changes to our business and product portfolio for many years. The road to a reduction in carbon requires collective action and sustainable procurement strategies have an important role to play in supporting these ambitions. By taking progressive actions such as adopting electric vehicle (EV) technology and switching to clean electricity, we can lead by example and begin to effect real change.”

UK: Breedon Group has appointed Donna Hunt as its first Group Head of Sustainability. In the newly-created role, she will be responsible for developing and implementing a sustainability strategy to shape the group's practices and performance, ultimately improving the sustainability of Breedon's operations, products and services.

Hunt holds over 20 years' experience having held several senior sustainability, environmental and stakeholder engagement positions across the energy, aerospace engineering and construction materials sectors. She has served on several cross-industry committees on sustainability-related topics and remains an active STEM (Science, technology, engineering, and mathematics) Industry Ambassador on behalf of the Mineral Products Qualifications Council (MPQC).

The Construction Products Association (CPA) has just forecast a 25% drop in construction output for 2020 in the UK due to Covid-19. And this is the optimistic prediction! It blamed the decline, which is said to be the sharpest ever recorded, on the country’s coronavirus-related lockdown. 60% of planned construction output was lost in April 2020 due to social distancing measures. This compares to a 6.5% decline in gross domestic product (GDP) forecast for 2020 by the International Monetary Fund (IMF) in April 2020 for the UK. OneStone Consulting’s Joe Harder in his Covid-19 Impact Analysis CIC 2025 report has forecast a 12.7% decrease in European cement production. Readers should keep in mind that construction output, GDP and cement production are all connected but not necessarily directly related.

Further details of note from the CPA include a direct link between the strength of lockdown measures and work lost, as well as differences between types of activity. So, for example, more construction output (in percentage terms) was reported lost in Scotland, where tighter lockdown measures were implemented. On the latter point, more output was lost in residential construction compared to non-residential with a similar trend reported in the repair, maintenance and improvement sector, again worsened in the residential part of this market. The sector that suffered the least was non-residential repair and maintenance as work on, currently, mostly deserted buildings and infrastructure was prioritised. One example of this may have been Aggregate Industries, the UK subsidiary of LafargeHolcim, which said this week that it had completed major works on the A14, a major regional trunk road, ahead of schedule. It didn’t directly make the link in its press release but quiet roads would have helped.

The CPA is touting the now-familiar range of letter-shaped economic recession shapes in the report, including ‘V’, ‘W’ and the dreaded ‘U’. However, the CPA’s Economics Director Noble Francis was more confident that infrastructure projects would bounce back fastest due to favourable investment cycles in utilities, government support for its high-speed railway scheme HS2 and, “greater ability to implement safe distancing for workers on larger sites.”

That last point ties in nicely with the operational guidance that the Mineral Product Association (MPA), the UK’s trade association for the heavy building material sector in the UK, released last week. This is all crucial information on a comprehensive and detailed scale along the lines released in other countries.

Much of this will be becoming second nature to cement industry workers and/or will be familiar to anyone who has watched US consultant John Kline discuss these issues on Global Cement Live. Yet there are some points worth discussing here such as ‘Avoid Distraction.’ This one’s all about remembering to keep in mind existing health and safety practices alongside all the coronavirus-related ones. All the usual health and safety regulations and advice remain in place and in some ways become even more important as there may be fewer staff working on socially-distanced sites, or first responders may be otherwise busy elsewhere. Another point from the MPA’s guidance is to ‘Provide More Time,’ which acknowledges that working with coronavirus measures will require more time. Other implications from a business changed by coronavirus are things like notifying the police when sites are closed and considering further security for such sites to minimise risk of theft. A lot of this stuff seems obvious but it’s easy to miss things.

For a recent review of the UK cement industry readers should refer to Edwin Trout’s feature in the June 2020 issue of Global Cement Magazine. One change since it was published has been Cemex’s proposal to mothball its 0.8Mt/yr South Ferriby integrated plant in Lincolnshire. The cement producer says it is not related to coronavirus but if the CPA’s predictions are accurate then it will make it that much harder to keep the plant open.

Everyone’s hoping for a ‘V’ shaped recovery from the coronavirus downturn in the UK and everywhere else around the world. Boots on the ground operating advice like that issued by the MPA and others is part of how the construction materials industries can work towards achieving this.

UK: The Construction Products Association (CPA) has predicted a 25% year-on-year decline in total national construction output in 2020. It said that the coronavirus lockdown resulted in the loss of 60% of planned construction output in April 2020, included 85% of homebuilding.

CPA economics director Noble Francis said, “Even under this most optimistic of scenarios, the country’s construction activity would suffer its sharpest fall ever recorded. Returns to site in May 2020 will focus on partially completed developments rather than new starts as house builders are expected to be cautious given uncertainty regarding demand. This uncertainty will also keep the recovery muted in commercial offices, industrial factories and the most severely-affected sub-sector, commercial retail.” He added, “A more positive outlook is expected for infrastructure activity thanks to a greater ability to implement safe distancing for workers on larger sites but also, vitally, thanks to HS2 being given the go ahead to proceed. An increase in activity from the five-year investment programmes within regulated sectors such as water and sewerage, roads and rail also adds to this more positive story.”
