Sweden: HeidelbergCement’s subsidiary Cementa has completed a feasibility study into electrifying its cement plant at Slite in Gotland as part of its Cemzero project. A report from the first phase of the project has been submitted to the Swedish Energy Agency.

The study found that using electricity to supply heat during the clinker production process is possible using plasma technology, although this needs to be tested on a larger scale. Using an electrified process was found to be competitive compared to other options for achieving high reductions in carbon emission. The production cost of cement would be doubled approximately but the research suggested that this might only mean a small percentage increase to the end cost of a building or an infrastructure project. Finally, the study reported that any future electrification of the Slite plant would work well with a planned expansion to wind turbine generation at the site. It would improve the energy balance and reduce the maximum power surplus that might occur.

Cementa and energy company Vatenfall will now look at how to build a pilot plant.

France: The SOLPART (Solar-Heated Reactors for Industrials Production of Reactive Particulates) project plans to test a pilot-scale version of its solar reactor from February 2019. The 50kW solar reactor will test a fluidised bed system at its PROMES (PROcédés, Materials and Solar Energy) testing site in Odeillo. The ultimate goal of the project is to test using a rotary kiln and a fluidised bed system to produce cement, lime, gypsum and other non-metallic products using only solar energy. The pilot scale reactor will test calcining limestone at a rate of 50kg/hr. Industrial partners involved with the project include Cemex.

US: Elixsys has completed a 100hr continuous pilot test to extract ammonium sulphate and calcium carbonate from flue gas desulphurisation solids at a coal-fired power plant in Pennsylvania. Products made using the company’s proprietary process meet the specifications for fertiliser-quality ammonium sulphate and technical-grade calcium carbonate.

The company intends to start a commercial-scale project of its technology in 2019 once it finds a utility partner. Full-scale operations are planned by 2022. The company is also starting pilot testing on another process to extract metals from coal ash.

France: Hoffmann Green Cement Technologies’ pilot plant at Bournezeau, Vendée is set to start commercial production of low-carbon cement products in January 2019. Construction of the 50,000t/yr unit is due to be completed in October 2018 with its inauguration scheduled for late November 2018, according to Batiactu. The plant will employ 10 workers initially and this will rise to 15 – 20 as production ramps up.

The producer intends to make cement products using metakaolin and blast-furnace slag. If the pilot plant is a success it then intends to raise funds to build a 0.5Mt/yr plant.

China: Anhui Conch has spent over US$7.9m on a 50,000t CO₂ capture and purification pilot project at its Baimashan cement plant in Anhui province. The unit is scheduled to start operation in the first half of 2018. The group has started the project in order to participate in the government’s ‘Intended Nationally Determined Contributions’ CO₂ emission reduction initiative.

US: CarbonCure has demonstrated an integrated CO₂ capture and utilisation (CCU) process from cement for concrete production in January 2018 at Cementos Argos’ Roberta plant in Calera, Alabama. The consortium - comprising Carbon Cure, Sustainable Energy Solutions (SES), Praxair, Cementos Argos and Kline Consulting - says it is the world’s first project to collect cement kiln CO₂ for subsequent utilisation downstream in concrete production and construction.

CO₂ emissions from the Roberta cement plant were captured by SES’ Cryogenic CO₂ Capture technology, transported by Praxair and reused in Cementos Argos' Glenwood, Atlanta concrete operations equipped with CarbonCure's CO₂ utilisation technology. The concrete manufactured with the waste CO₂ from the Roberta cement plant was then used in a local construction project in the greater Atlanta area. Design partners and fellow members of CarbonCure’s Carbon XPRIZE team such as LS3P Architects, Uzun + Case Structural Engineering, and Walter P Moore Structural Engineers completed the end to end integrated solution by creating demand for CarbonCure concrete products in the marketplace. Kline Consulting oversaw the commissioning and reporting of the industrial demonstration.

The project was an extension of Team CarbonCure's participation in the US$20m NRG COSIA Carbon XPRIZE Challenge, which incentivises and accelerates the development of integrated CCU technologies and new markets that convert CO₂ emissions from coal and natural gas power generation into valuable products.

Belgium: HeidelbergCement has hosted a ground breaking ceremony for the Calix carbon capture pilot at CBR’s cement plant at Lixhe. The ceremony itself took place at the Liège Oupeye Water Treatment Plant near Liège as part of the inaugural Innovation in Industrial Carbon Capture Conference. The two-day event, which took place on 7 – 8 February 2018, was organised by the Low Emissions Intensity Lime And Cement (LEILAC) Consortium, a European Union (EU) Horizon 2020 backed research and innovation project.

Construction work on the pilot at the cement plant is scheduled to start imminently. The project will test Calix’s carbon capture technology for two years at an operational cement plant. The technology has previously been used in the magnesite calcining sector.

Over 130 delegates from industry, academia and government attended the conference. The agenda was designed to encourage discussion and knowledge sharing across key stakeholder groups with a strategic interest in innovation in carbon capture technology. As part of the programme, the wider challenges faced by the cement and lime sectors in Europe were also explored focusing on how EU industries can contribute to reaching climate change targets, the role of innovation and company entrepreneurship and a knowledge exchange fair on technology.

The LEILAC consortium, which consists of representatives from the lime and cement industries, technology and engineering providers and research institutes, has set up as an industrial project securing Euro12m in EU funding in order to demonstrate technology to reduce carbon emissions from cement and lime industries.

Austria/Germany/Italy: The European Cement Research Academy (ECRA) has launched its oxyfuel carbon capture pilot projects at HeidelbergCement’s Colleferro plant in Italy and LafargeHolcim’s Retznei plant in Austria. The two locations were chosen form a shortlist of five sites. The pilots will test oxyfuel technology on an industrial scale. The test phase of the research is expected to cost Euro80m and the cement industry has contributed Euro25m towards this. ‘Substantial’ funding from European or national research schemes is being sought.

“The technical feasibility of oxyfuel technology can only be proven in real-scale application, but we have sufficient information from our research to believe that we will obtain a positive result after the trials” said Daniel Gauthier, chairman of ECRA.
