Taiheiyo Cement to start CO2 capture project at Kumagaya plant using Carbon Clean technology

21 April 2021

Japan: Taiheiyo Cement plans to start a CO2 capture demonstration project at its Kumagaya plant in Kumagaya City, Saitama. It will use technology for CO2 chemical absorption supplied by UK-based Carbon Clean, which has been awarded by Japan-based Marubeni Protechs in Japan. The project will have a capacity of 10t/day and demonstration tests will begin in September 2021. Taiheiyo Cement says that it believes that CO2 recovery technology from cement kiln flue gas will require compact equipment that could be installed in cement plants and that suitable amine solvents for cement kiln flue gas are essential conditions. Its ultimate goal is to establish a technology that can be used to help it reach carbon neutrality by 2050.

The cement producer has been developing this technology as a sole grant recipient of the ‘Development of Carbon Circulation Technology for the Cement Industry,’ a project funded by the New Energy and Industrial Technology Development Organization (NEDO) which was awarded in June 2020. It also launched its internal Carbon Neutral Technology Development Project Team in April 2020, which has led on the project.

Marubeni Protechs, a wholly owned subsidiary of Marubeni Corporation, which invested in Carbon Clean, have been involved in a variety of domestic and international projects involving equipment supply and construction. The project at the Kumagaya plant is expected to be the first CO2 capture plant that Marubeni Protechs and Carbon Clean have introduced in Japan. Marubeni Protechs and Carbon Clean intend to jointly introduce CO2 capture plants in the future.

CarbonBuilt and CarbonCure Technologies win carbon capture and storage design competition

20 April 2021

US/Canada: XPrize has named CarbonBuilt and CarbonCure Technologies as the winners of carbon capture and storage (CCS) design prizes worth US$20.0m. The competition ran at two power plants in Wyoming, US and Alberta, Canada. CarbonBuilt won the contest at the Wyoming plant with a concrete-curing based system. The concrete produced has a lower carbon footprint than conventionally produced concrete, according to XPrize. CarbonCure Technologies won the Alberta contest with a design based on carbonating the water used in washing cement trucks. This reportedly formed a concrete-strengthening slurry.

XPrize has partnered with Elon Musk and the Musk Foundation to launch a second round of CCS design prizes worth a total US$100m.

Cement news, abridged

07 April 2021

Global Cement Weekly celebrates its 500th edition this week. This corresponds to nearly a decade’s worth of news and comment upon the cement industry, since the first edition went out in early June 2011. Time is brief, so the quick version of all of this is as follows: China; production growth; production overcapacity; grinding; corporate mergers; regionalisation; CO2; digitisation; and coronavirus.

Those looking for the longer version should read Peter Edwards’ review of the 2010s in the December 2019 issue of Global Cement Magazine. Although be warned, few were expecting a global pandemic to rock markets and possibly hasten future trends when that article was written. Those looking for the even longer version should read the last 10 years of the magazine and the website… and then let us know what we missed.

Looking back at the first few editions of Global Cement Weekly brings to mind the LP Hartley quote, “the past is a foreign country; they do things differently there.” It’s all very familiar until one comes across the little things that makes one realise how much has actually changed.

For example, countries were imposing import tariffs on cement, companies were buying each other, national cement associations were lobbying hard for their members and cement plants were investing in alternative fuels equipment. All that stuff has been happening continually over the last decade and right into this week, with Russian media announcing who has won the auction to buy Eurocement and LafargeHolcim closing its deal to buy Firestone Building Products. Yet, Lafarge and Holcim were still separate companies and Italcementi was independent in 2011. On the sustainability side, Norcem and its parent company HeidelbergCement Group, with the European Cement Research Academy (ECRA), had just started a partnership agreement with Aker Clean Carbon (ACC) to study post-combustion CO2 capture technology at Norcem’s plant in Brevik, Norway. Jump forward nine years and Norcem signed a deal with Aker Solutions in mid-2020 to order a full scale CO2 capture, liquification and intermediate storage plant at Brevik.

The big numbers from the United States Geological Survey (USGS) show that global cement production grew by 24% to 4.1Bnt in 2020 from 3.3Bnt in 2010. However, the big growth had stopped by around 2013 and production has hovered between 4.0Bnt/yr and 4.2Bnt/yr ever since. Alongside this, Getting the Number Right (GNR) data indicates that net CO2 emissions for cementitous products fell by 4% to 610kg/t in 2018 from 636kg/t in 2010. The former may show a levelling off of production as the Chinese market stabilised in the 2010s but the latter shows the progress that has been made in reducing cement-related CO2 emissions and the scale of the challenge that remains ahead.

Cement industry readers should not lose heart about the future of the industry though, while environmental pressure continues to mount. Graph 1 above shows the embodied CO2 and energy of common building materials. Cement has been rightly identified as a major emitter of CO2 but any society that desires to build strong structures cheaply and at scale requires concrete to do so whilst the data above remains unchallenged. The ratios may change, such as the perennial energy-cost influenced tug-of-war between asphalt and concrete roads, but concrete remains the only game in town. For now. At which point cement production becomes all about reducing the CO2 emissions or capturing them, and determining who exactly pays for this. This then brings us to the present with the European Union Emissions Trading Scheme carbon price of over Euro40/t and other schemes popping up all around the planet. One echo from one of the early editions of Global Cement Weekly was the furore over Australia’s attempt at a carbon tax in the early 2010s. It was repealed in 2014.

One prediction about how the 2020s might be summarised for the cement industry is this: how to get away with pumping out all that CO2? Let’s see what the next decade will bring.

Cemex Zement establishes Carbon Neutral Alliance to achieve net zero emissions at Rüdersdorf cement plant

18 March 2021

Germany: Mexico-based Cemex subsidiary Cemex Zement has set up an innovation acceleration partnership called Carbon Neutral Alliance to support its work to achieve net zero CO2 emissions at its Rüdersdorf cement plant by 2030. The association will work to develop industrial-scale demonstration projects in line with the company’s Future in Action programme. Its scope will include carbon capture and storage (CCS), the transformation of captured CO2 into building materials, synthetic fuels and green hydrocarbons, hydrogen production and waste heat recovery (WHR). Cemex plans to share the knowledge gained by the alliance across its global cement network.

Managing director and Rüdersdorf plant manager Stefan Schmorleiz said, "It is expected that CO2 will be further processed to convert to new forms of energy and materials for use locally by industrial, residential, and transport sectors. Together with our partners, we will take feasibility studies through to economic solutions to decarbonising cement production.”
