Portugal: Cimpor is participating in a consortium, led by power company Rega Energy, which plans to invest Euro100m in developing scalable green hydrogen production plant technologies. The consortium will deploy infrastructure for its upcoming Vale Hidrogénio Verde Nazaré (NGHV) green hydrogen plant by 2023, including a dedicated 40MW solar-powered electricity grid. It will commission its first green hydrogen plant by 2026, creating 140 new jobs. The consortium aims subsequently to scale up the plant to a renewable power consumption of 600MW. It hopes that, when fully commissioned, the NGHV plant will be a reference project for green hydrogen production.

The data on cement consumption for 2021 in Spain is out this week and it looks promising. As the national cement association Oficemen explained, last year was the sector’s best for over a decade, nearly reaching 15Mt consumption and exceeding the figure in 2019 before the Covid-19 pandemic started. Oficemen also singled out particular strong performance in December 2021. It now expects this growth trend to continue into 2022 with a forecast of 5% to 15.6Mt predicted based on both domestic and infrastructure segments.

The Spanish cement industry reached a peak consumption of over 50Mt in the late 2000s before hitting a near-50 year low in the 2010s in the wake of the 2008 financial crisis. The market then started to recover in the second half of the 2010s until Covid-19 came along. A report on the Spanish cement market to the start of 2021 that lays out the situation can be found in the February 2021 issue of Global Cement Magazine. The larger news stories since then have been Votorantim Cimentos’ growth in the market through its acquisitions of FYM and Cementos Balboa, and Çimsa Çimento’s final completion of its deal to buy the Buñol white cement plant from Cemex. Each of these stories involve an integrated cement plant changing ownership.

Looking back at Oficemen’s summary describing 2012 depicts a much different dwindling market. However, one commonality it shares with the association’s roundup for 2021 is that it complains about the country’s disadvantage in electricity costs compared to its neighbours. Back in 2012 this was framed as holding back exports. As Oficemen noted at the time it exported 5.9Mt of cement in 2012, less than half the 13Mt it exported in 1983. Jump forward to 2021 and exports are now 6.8Mt. Energy is still a key issue though. Now Oficemen’s president, José Manuel Cascajero Rodríguez, says that the sector’s production costs have increased by 25% since the latest round of electricity price rises began. He then compares the cost of energy intensive industry in Spain unfavourably against France and Germany and calls for a structural change in the Spanish electricity market to make prices more predictable. Cement producers elsewhere in Europe and beyond may share Oficemen’s concerns regard unpredictable energy prices over the last six months but electricity has been a particular issue for Spain for a long time. To take one recent local example, in November 2021 Cementos Cosmos said it was planning to scale down the production of clinker at its Córdoba cement plant as a result of the high cost of electricity.

The other issue that gets raised in Oficemen’s 2021 summary is competition from cement importers outside the European Union (EU) and the necessity of a border carbon adjustment mechanism (CBAM) to take in account carbon taxation for producers within Europe. To jump back a bit, back in May 2021 the EU Emissions trading Scheme (ETS) reached Euro50/t. Then in December 2021 Cembureau, the European cement association, published a calculation predicting that if the EU ETS CO₂ cost made it to Euro90/t then this could represent 12 - 15% of the production costs of cement producers. Well, as readers will have guessed, the EU ETS beat Euro90/t on 2 February 2022 and then rose to Euro96.7/t on 7 February 2022. Answers in an email for when readers think the EU ETS price will top Euro100/t.

All of the above feeds neatly into the week’s other big Spanish news story: Cemex and Synhelion have successfully produced clinker from concentrated solar radiation at a pilot unit at the Very High Concentration Solar Tower of IMDEA Energy near Madrid. It’s early days yet as the process needs to be scaled up but, make no mistake, this is a big story. An interview with the team behind Cemex and Synhelion’s solar concentration project can be found in the December 2020 issue of Global Cement Magazine for more information. The SOLPART (Solar-Heated Reactors for Industrials Production of Reactive Particulates) project in France did similar research a few years ago but it didn’t reach the 1500°C target required to reach the sintering phase where clumps of clinker form. US-based Heliogen has been trying to industrialise concentrated solar energy but not much has been heard about its cement-industry ambitions since it said it reached temperatures of about 1000°C in 2019.

The relevance of an eventual full-scale concentrated solar unit for the entire production line or just the preheater and/or calciner at a cement plant in Spain makes considerable sense. At a stroke energy costs are reduced, diverted to a renewable source and any desired CO₂ capture becomes, in theory, easier and cheaper. Cemex said in the interview with Global Cement Magazine that the tentative next step would be a pilot unit at a cement plant, although, candidate plants could be in the US or Mexico, as well as Spain. Another side of the drive to cut energy and carbon costs can also be seen in a couple of photovoltaic solar projects supplying cement plants that were announced in 2021 for Spanish plants run by Cemex and Cementos Cosmos.

We leave the Spanish cement sector in a growth phase but with plenty of challenges ahead, not least from electricity costs and the mounting cost of carbon. Yet in common with other countries in Europe the industry faces a high-wire balancing act between staying economically viable and inching towards net zero. It’s conceivable that an industrial scale concentrated solar unit at a cement plant in Spain by 2030 might steady the wobbles along the way.

Kenya: Bamburi Cement has signed a power purchase agreement (PPA) with Momnai Energy to set up two solar plants. One 14.5MW unit will be situated next to its integrated Mombasa plant and the other 5MW unit by its Nairobi grinding plant. This will account for up to approximately 40% of the cement producer’s total power supply. Construction of the solar power plants is scheduled to begin end of 2022, after requisite regulatory approvals with expected completion within a year.

“We are elated to be making this step towards switching to more affordable and clean energy that will not only lead to a significant reduction in power costs but also bring us closer to our goal of achieving net zero carbon emissions,” said Miriam Ngolo, Bamburi Cement’s Strategy and Business Development Director.

Other recent sustainability work by the subsidiary of Switzerland-based Holcim has included substituting heavy fuels with alternative fuels like biomass, including rice husks, and other waste material such as waste tyres and waste oil in its operations.

India: Dalmia Cement (Bharat) has commissioned a 14.7MW solar power plant at its 1.3Mt/yr Kapilas grinding plant in Odisha. The producer says that the new power plant multiplies its total solar power capacity in Cuttack District by six to 17.1MW from 2.4MW.

The company said "Furthering Dalmia Cement (Bharat)'s sustainability goal of becoming carbon negative by 2040, this initiative will enhance the plant's energy efficiencies."

India: Orient Cement’s board of directors has approved a change to the company’s agreement for the acquisition of a 26% stake in renewables company AMPSolar Systems. Indiainfoline News Service has reported that the producer will now pay US$556,000 for the stake, up by 2.7% from the US$541,000 it previously negotiated in December 2020.

AMPSolar Systems recently commissioned its new 13.5MW solar power plant.

India: Dalmia Cement (Bharat) has commenced cement production at its upgraded 2.9Mt/yr Murli cement plant in Maharashtra. The company invested US$125m to install a new fueling system, waste heat recovery (WHR) plant and solar power plant at the facility. It acquired the plant from Murli Industries for US$55.2m in 2020.

The new commissioning brings Dalmia Cement (Bharat)’s total installed capacity to 35.9Mt/yr.

Pakistan: Power Cement has signed an agreement with Burj Solar Energy for the procurement of electricity on a fixed tariff for the next 20 years. The supplier plans to build a 7MW solar power plant to support the deal. The unit is expected to be operational by mid to late 2022. Power Cement said it took the decision to cut growing electricity costs.

Saudi Arabia: Qassim Cement has entered into a preliminary agreement with China-based Chengdu Design & Research Institute of Building Materials Industry (CDI) for the engineering, supply and construction of a cement mill at its integrated Buraydah plant. The new mill will have a production capacity of 300t/hr. The project is budgeted at around US$40m and it has an implementation period of 15 months. More binding detailed contracts are expected to be signed by mid-January 2022.

The cement company also plans to appoint a consultant to define the scope of work and identify contractors to build a 30MW solar unit near the Buraydah plant. It said that the company would not incur any capital or operational expenditure as the payment would be based on actual consumption. The solar unit project is part of the country’s Saudi Vision 2030 strategic framework to reduce dependence on oil.

Honduras: Cementos Argos plans to expand the production capacity of its 1Mt/yr Piedras Azules cement plant by 35%. The plan is part of a group of planned projects, including solar power and alternative fuels, with a total investment value of US$23m. The company expects to complete all of the work before 2024. It says that the expanded operations will generate 500 new direct job opportunities.

The company will increase its energy supply from the Comayagua solar power plant to 25% of the plant’s requirements from 20% at present. It will also establish a new 1.2MW solar power plant at Río Blanquito. The cement producer will also strengthen its industrial waste co-processing operations with the aim of achieving 12% refuse-derived fuel (RDF) substitution rate by 2030, the equivalent of 5500t/yr. If reached, this will reduce the company’s carbon footprint in the country by 14%.

Chief executive officer (CEO) Luis Eduardo Tovar said "This investment is a vote of confidence of Argos in Honduras and represents our commitment to the country's economic reactivation and our firm determination to contribute to the consolidation of prosperous and sustainable communities based on competitive and visionary initiatives.” He continued “We will continue our efforts to promote the development of Honduran families through the creation of social value at a national level."

India: Dalmia Cement plans to invest US$75.2m in a 2.6Mt/yr expansion to its Bokaro grinding plant in Jharkhand. The company says that the work will increase the plant’s capacity by 70% to 6.3Mt/yr from 3.7Mt/yr. US$33.2m will go towards the installation of new solar power plant. The company will also set up a waste management facility at the site, using US$1.06m of the investment.

Managing director Puneet Dalmia said “As we are further investing in the Eastern India market to participate in its economic growth story, we are also taking our corporate responsibility seriously by placing the utmost importance on environmental protection and social impact. We are confident that the employment generated through our investments and the skill enhancement in our social initiatives will help create a progressive ecosystem where we help people become independent and self-sufficient. We are excited and look forward to partnering with the state to achieve our business, social and sustainability goals.”
