This is the third in a series of articles I have written about flow battery technology. Agora Energy Technologies‘Specific technology. The first article discusses flow batteries in general and why they are so promising for grid storage. The second discusses the diversity of Agoran. This article focuses on the use of technology as a compelling alternative, which is immediate and costly.
The past three years have been immersed in industrial processes and chemical engineering for me, and the implications of global warming. Of CleanTechnica Report on Carbon Engineering Carbon disintegration was a major effort in industrial processes, as were many other articles. Review Cement production, With meaningless use and without Focusing on solar energy It was another.
This led me to a deep interest in climate change issues. My reviews and research over the past few years have helped me understand the major solutions to energy, transportation and biological carbon sequencing, but there is still a lot of carbon and pollution released in industrial processes. As an example, there is a $ 44 billion global carbonate market.
Potassium carbonate is one of the many things we use every day. It is used in soap, glass and Chinese food. It serves as a drying agent in chemical processes. It is found in both Asian noodles and Dutch cocoa powder. Winemakers use it. It is a water softener and a fire extinguisher. It is used in welding and animal feed.
Sodium carbonate is equally widely used. Is in Glass, paper, rye, soaps and soaps. It is used for water softening. It is a dietary supplement. As a weak, safe to hold foundation, it has been used in many chemical processes. More than 40 million metric tons are produced each year, which is several kilograms per person on earth.
They represent an estimated $ 44 billion in annual global markets. And the current process of doing them is in many ways very bad.
Take, for example, sodium carbonate. About 75% of the world’s sodium carbonate is made by the Solvia process. The United States derives most of its sodium carbonate from Wyoming’s giant Toronto deposit.
The Solvay process was invented in 1861 and is still widely used today. In a four-step chemical engineering process that produces and uses CO2 at various points in the process, it produces CO2 through an ammonia-based brain. And of course, in the U.S. Department of Occupational Safety and Health, there is the most toxic ammonia in the 35-minute exposure limits on gas ammonia levels within 35 minutes. Today, ammonia is a by-product of hydrogen production from fossil fuels 8-35 times as much as CO3 as hydrogen. Exposure to low levels of ammonia can have irreversible health consequences. Ammonia is often reused in small amounts, but it is important to get rid of it completely.
The Solvay process actually contains some of the CO2 produced in the first stage for later use, but overall, the implanted process is 2.74 times more refined than the amount of carbohydrates in CO2.
In the first place, the heat source interested me. That stage of the process is the same for cement, incidentally. It requires high temperatures in the range of 600 to 1000 degrees Celsius to produce fast lemons and CO2. Unlike cement, where all the CO2 is released into the atmosphere, some of the CO2 and all of the rapid residues are used in the later stages of the process.
As a reminder, a Lafarge Cement expert told me that when I examined cement for 160 years, the limestone furnace, which was not seen as an industrial process, did not have a good process for capturing CO2 emissions. Exhaust CO2 is not difficult, it is expensive, so it cannot be done without a very good economic reason.
Then there is the heat challenge, the third step in the process is strictly exothermic, which means it provides a lot of heat, not just usage. One of the key challenges in the process is maintaining adequate temperature. That is usually done by cooling from ground sources, by challenging sources in many parts of the world, where groundwater is shutting down or shrinking when it is heated in a well-ventilated area with a closed-loop generator. Solvi’s company closed its four sections in São Paulo, Brazil, in 2014. Due to the drying up of the river, the future of global warming is a testament to the large number of heavy-duty industrial plants in the area.
The second example of heat treatment in step 4 is also interesting. That requires another oven at a temperature of about 300 degrees Celsius. Every time I see heat in industrial processes these days, I think it comes from fossil fuels, and I am not surprised to find that it is the best source of energy for the solving process. Coke, Synthetic coal products.
Not only that. The Solvay process is much less polluted than the replacement Liblank process, but domestic stations account for 50% more waste products than sodium carbonate. Solva, New York, renamed the Solva plant, has huge garbage dumps that have polluted the area and contributed to its proximity. Lake Ondaga It is known to be a superficial site.
I did not make a similar assessment of the environmental impacts of the US Trojan Mining and Sodium Carbonate Processor, but at first glance it seems that the use of toxic chemicals and challenging flows as well as high CO2 emissions. .
Why is this dizziness so exciting? all right , Agora technology can produce sodium carbonate in two stages without any heat and without any heat treatment at all.
wait. What? A battery, not a chemical plant, right?
Well, yes. The closed model rotates the model between the base form and the paid form and the background. However, in some cases, the modified open-cycle model produces sodium carbonate after the second cycle, instead of returning it to CO2 by weight solution with water. And both, like batteries, produce electricity in the charging stage and in the liquid phase.
Thus, ammonia-based, high-temperature, high-cooling, five-step process results in a much shorter process. Electricity is cheap at night or at other times, and it is possible to charge the battery with all renewable energy if possible. Then, instead of reversing the process as an open-flow approach during the day, it sends special chemistry into the aorta cells and produces carbon in solutions and electricity. Drying carbonate solutions throughout the day, from lighting to pumps, etc., can be done in the production room.
The resulting sodium carbonate is also pure. It is a pure compound in pure water. Heat the water to keep it warm, and the hygiene must be more than 98% hygienic, usually for food additives. In my opinion, there is enough electricity in the battery to run directly with the CEO Dr. Christina Gaying, but there is more than enough to use heat pump technology in COP 4 or to dump it on a waste source. Leave a lot of electricity for industrial heating elsewhere, and for sale in an industrial facility or on the grid.
Therefore, this technology can produce the highest quality industrial chemicals in the world, valued at tens of billions of dollars, using renewable energy from anywhere.
Agora CO2-based Redx flow is battery technology From the future part of the industry.
Full description. I have a professional relationship with Agora as a strategic consultant and board observer. A.D. At the end of 2019, I had an initial strategy session with Agora on Redox Flow Battery Technology and was inspired by what they had, and my formal role with the company began in early 2021. I promise to be realistic and honest. As always, but know my connection.
