Decarbonization Roadmap for California’s Cement and Concrete Industry

california-160550_640.png

The cement industry accounts for over 5 percent of current man-made carbon dioxide emissions worldwide. World cement demand and production are increasing; annual world cement production is expected to grow from approximately 4,100 million tonnes (Mt) in 2015 to around 4,800 Mt in 2030 and grow even further after that. The largest share of this growth will take place in developing countries, especially in the Asian continent.

According to USGS, United States produced around 86 Mt of cement in 2016 making it the third largest cement producer in the world after China and India. The state of California has 10 cement plants that together produced around 10 Mt of cement in 2015 making it the second largest cement producing state in the U.S. after Texas. This significant cement production in California is associated with a substantial energy use and greenhouse gas (GHG) emissions in the state. The cement industry in California is the largest consumer of coal in the state. Therefore, there is a need to develop a roadmap on how to reduce energy use and GHG emissions related to cement and concrete production in California.

Given our extensive experience in this area, Global Efficiency Intelligence, LLC is conducting a study for the Sierra Club to develop a roadmap for decarbonizing California’s cement and concrete industry. In this study, we will look into current status of the cement and concrete production in California and conduct a benchmarking analysis for the energy use and emissions of the cement industry in California in comparison with some other key cement producing countries. In addition, we will look into options that can help to decarbonize the cement and concrete production in California such as energy efficiency, fuel switching, alternative raw material and products, and carbon capture, utilization, and storage (CCUS).

18 Emerging Technologies and 180 Commercialized Technologies and Measures for Energy and Water Efficiency, and GHG Emissions Reduction in the Textile Industry

The textile industry uses large amounts of electricity, fuel, and water, with corresponding greenhouse gas emissions (GHGs) and contaminated effluent.  With regard to energy use, the textile industry’s share of fuel and electricity use within the total final energy use of any one country depends on the structure of the textile industry in that country. For instance, electricity is the dominant energy source for yarn spinning whereas fuels are the major energy source for textile wet processing.

In addition to using substantial energy, textile manufacturing uses a large amount of water, particularly for wet processing of materials, and produces a significant volume of contaminated effluent. Conserving water and mitigating water pollution will also be part of the industry’s strategy to make its production processes more environmentally friendly, particularly in parts of the world where water is scarce.

In 2016, the world’s population was 7.4 billion; this number is expected to grow to 9.5 billion by 2050. The bulk of this growth will take place in underdeveloped and developing countries. As the economy in these countries improves, residents will have more purchasing power; as a result, per-capita consumption of goods, including textiles, will increase. In short, future population and economic growth will stimulate rapid increases in textile production and consumption, which, in turn, will drive significant increases in the textile industry’s absolute energy use, water use, and carbon dioxide (CO2) and other environmentally harmful emissions.

Having the higher education background in both textile technology engineering and energy efficiency technologies, I wrote a report on commercially available energy-efficiency technologies and measures for the textile industry several years ago. This report included a review of over 180 commercialized energy efficiency technologies and measures for the textile industry based on case-studies around the world. In addition to conserving energy, some of the technologies and measures presented also conserve water. The report can be downloaded from this Link (Hasanbeigi 2010).

Several other reports also document the application of commercialized technologies. However, today, given the projected continuing increase in absolute textile production, future reductions (e.g., by 2030 or 2050) in absolute energy use and CO2 emissions will require further innovation in this industry. Innovations will likely include development of different processes and materials for textile production or technologies that can economically capture and store the industry’s CO2 emissions. The development of these emerging technologies and their deployment in the market will be a key factor in the textile industry’s mid- and long-term climate change mitigation strategies.

However, information is scarce and scattered regarding emerging or advanced energy-efficiency and low-carbon technologies for the textile industry that have not yet been commercialized. That was why a few years ago, I wrote another report that consolidated available information on 18 emerging technologies for the textile industry with the goal of giving engineers, researchers, investors, textile companies, policy makers, and other interested parties easy access to a well-structured database of information on this topic. Table below shows the list of the technologies covered.

Table. Emerging energy-efficiency, water efficiency, and GHG emissions reduction technologies for the textile industry (Hasanbeigi 2015)

A few years ago when I conducted several day-long training on energy efficiency in the textile industry for hundreds of engineers and manager of textile companies in China, one major feedback we received, which did not surprise me, was that they did not know about most of the commercialized and emerging technologies we introduced. Engineers and manager are busy with day-to-day routine which rarely involves energy efficiency improvement.  

Also, you can check out the Energy Efficiency Assessment and Greenhouse Gas Emission Reduction Tool for the Textile Industry (EAGER Textile), which we developed a few years ago. EAGER Textile tool allows users to conduct a simple techno-economic analysis to evaluate the impact of selected energy efficiency measures in a textile plant by choosing the measures that they would likely introduce in a facility, or would like to evaluate for potential use.

56 Emerging Technologies for Energy-efficiency and GHG Emissions Reduction in the Iron and Steel Industry

Iron and steel manufacturing is one of the most energy-intensive industries worldwide. In addition, use of coal as the primary fuel for iron and steel production means that iron and steel production has among the highest carbon dioxide (CO2) emissions of any industry. According to the International Energy Agency, the iron and steel industry accounts for the largest share – approximately 27 percent – of CO2 emissions from the global manufacturing sector.

Figure 1: World steel production in 2015 by countries and regions (worldsteel 2016)

Figure 1: World steel production in 2015 by countries and regions (worldsteel 2016)

China accounts for around half of the world’s steel production. Annual world steel demand is expected to grow from approximately 1,410 million tonnes (Mt) of crude steel in 2010 to approximately 2,200 Mt in 2050. The bulk of this growth will take place in China, India, and other developing countries in Asia (Bellevrat and Menanteau 2008). This significant increase in steel consumption and production will drive a significant increase in the industry’s absolute energy use and CO2 emissions.

Studies have documented the potential to save energy by implementing commercially-available energy-efficiency technologies and measures in the iron and steel industry worldwide. However, today, given the projected continuing increase in absolute steel production, future reductions (e.g., by 2030 or 2050) in absolute energy use and CO2 emissions will require further innovation in this industry. Innovations will likely include development of different processes and materials for steel production or technologies that can economically capture and store the industry’s CO2 emissions. The development of these emerging technologies and their deployment in the market will be a key factor in the iron and steel industry’s mid- and long-term climate change mitigation strategies.

Many studies from around the world have identified sector-specific and cross- energy-efficiency technologies for the iron and steel industry that have already been commercialized (See figure below). However, information is scarce and scattered regarding emerging or advanced energy-efficiency and low-carbon technologies for the steel industry that have not yet been commercialized.

My colleagues at Lawrence Berkeley National Laboratory and I wrote a report that consolidated available information on emerging technologies for the iron and steel industry with the goal of giving engineers, researchers, investors, steel companies, policy makers, and other interested parties easy access to a well-structured database of information on this topic.

The information about the 56 emerging technologies for the steel industry was covered in the report and was presented using a standard structure for each technology. Table below shows the list of the technologies covered.

Table 1. Emerging energy-efficiency and CO2 emissions-reduction technologies for the iron and steel industry (Hasanbeigi et al. 2013)

Shifting away from conventional processes and products will require a number of developments including: education of producers and consumers; new standards; aggressive research and development to address the issues and barriers confronting emerging technologies; government support and funding for development and deployment of emerging technologies; rules to address the intellectual property issues related to dissemination of new technologies; and financial incentives (e.g. through carbon trading mechanisms) to make emerging low-carbon technologies, which might have a higher initial costs, competitive with the conventional processes and products.
