A novel reactor design transforms CO2 emissions from small boilers into methane fuel, providing a promising strategy for addressing climate change.
Cutting carbon emissions from small-scale combustion systems, like boilers and other industrial devices, is essential for achieving a sustainable, carbon-neutral future. Boilers, which are prevalent in numerous industries for critical functions such as heating, steam generation, and power production, play a major role in greenhouse gas emissions.
Boilers are generally quite efficient. As a result, it is difficult to reduce CO2emissions simply by improving the combustion efficiency. Therefore, researchers are exploring alternative approaches to mitigating the environmental impact of CO2 emissions from boilers. One promising strategy to this end is to capture the CO2 emitted from these systems and convert it into a useful product, such as methane.
Researchers developed a method using distributor-type membrane reactors to convert CO2 emissions from small boilers into methane, significantly improving efficiency and offering a versatile tool for reducing greenhouse gas emissions
In order to make this possible, it has been made clear that a specific type of membrane reactor is necessary. The membrane reactor is called the distributor-type membrane reactor (DMR) and the purpose of this is for it to make chemical reactions possible, whilst simultaneously being able to separate gases. One of the reasons why there is sudden interest in DMRs, is because so far, there is very little research around the effect of these systems. Therefore, throughout this project, a group of researchers from Japan and Poland, led by Professor Mikihiro Nomura from Shibaura Institute of Technology in Japan and Prof. Grzegorz Brus from AGH University of Science and Technology in Poland, started to research into the use of DMRs. Their focus landed on what kind of effect these systems could have on converting CO2 into methane, particularly in small-scale systems like boilers.
To conduct this study, the team of researchers started a ‘two-pronged’ approach which focused on finding a solution through the use of numerical simulations and experimental studies. Throughout this simulation the team chose to look into how gases flow and react under different conditions and this led them to the ability to minimize the temperature variations, which allowed them to find a way to ensure that energy consumption is optimised while methane production can remain dependable. On top of this, the researchers also explored the impact of the reactor size and in doing this, they discovered that increasing the size of the reactor facilitated the availability of hydrogen for the reaction. The only downside to this, is that the team had to balance the careful tradeoff between the benefit of higher hydrogen availability, which required careful temperature management to avoid overheating.
So far, the work that has been done on this study has shown that the use of this DMR system, could be a promising solution to the problem of tackling a major source of greenhouse gas emissions. This system has been portrayed as a successful and excellent solution to the issues that come with boilers and it can be said that this system is able to convert CO2 emissions into usable methane fuel. Therefore, it is clear that this method works well and is a versatile solution, which is an excellent tool for efficient CO2 utilisation, within industries and households.
Prof. Nomura, commented, “This DMR design helped us reduce temperature increments by about 300 degrees compared to the traditional packed bed reactor.” Nomura continued, “When the CO2 concentration was around 15%, similar to what comes out of the boilers, the reactor was much better at producing methane. In fact, it could produce about 1.5 times more methane compared to a regular reactor that only had pure CO2 to work with.”
Ethylene is a very important chemical material. It is used in the manufacturing of plastics, solvents, cosmetics and other important products. The reason for having such diverse utility is that ethylene has become a very valuable substance. On the other hand, the whole world is troubled by the increasing amount of carbon dioxide (CO2). Now scientists have discovered an effective way by which they can convert carbon dioxide into ethylene.
Solutions to these challenges
Yu Huang, co-corresponding author of this detailed study published in Nature Catalyst and professor of Materials Science and Engineering at UCLA, said, “Our fossil fuels are on the verge of extinction, along with this, climate change is also posing no less challenges.
Dependence on fossils will end
Professor Huang said, “A substance that can effectively convert greenhouse gases into a value-adding fuel and chemical feedstock would prove to be a very important step in reducing global warming.” This will also eliminate our dependence on fossil fuels. This integrated experimental and theoretical analysis shows a sustainable path for CO2 use
Use of copper is an old idea
The study’s co-author William A. Goddard III and the Charles and Mary Ferkel Professor of Chemistry, Materials Science and Applied Physics at Caltech say the idea of using copper to catalyze this reaction was an old one, but it was an important one. The point was to speed up the rate of this reaction so much that industrial production would be possible. He says that this study shows a concrete path that has the potential to convert ethylene production into a green industry by using carbon dioxide.

Splitting carbon dioxide (CO2) into carbon and oxygen can in fact be accomplished, but there is a catch: doing so requires energy.

Climate change by co2
Carbon dioxide (CO2) is a greenhouse gas that contributes to climate change by trapping heat in the Earth’s atmosphere. This effect is similar to the way glass in a greenhouse warms the air inside. Without the natural CO2 in the atmosphere, Earth might be too cold to support life, but increasing levels of CO2 can cause global warming
Human activities like burning fossil fuels, deforestation, and agriculture have increased atmospheric CO2 levels since the Industrial Revolution. In 2022, the global average atmospheric CO2 was 417.06 parts per million (ppm), which is 50% higher than before the Industrial Revolution. At the current rate of increase, some predict that CO2 levels could reach 500 ppm within 50 years, which could lead to global temperature increases of more than 3 degrees Celsius (5.4°F). Climate scientists say that this level of warming could cause extreme weather events and sea level rise that could endanger food supplies
Carbon dioxide in the atmosphere warms the planet, causing climate change. Human activities have raised the atmosphere’s carbon dioxide content by 50% in less than 200 years
How does increased CO2 affect climate change?
Without carbon dioxide, Earth’s natural greenhouse effect would be too weak to keep the average global surface temperature above freezing. By adding more carbon dioxide to the atmosphere, people are supercharging the natural greenhouse effect, causing global temperature to rise

Takeaways. We already see effects scientists predicted, such as the loss of sea ice, melting glaciers and ice sheets, sea level rise, and more intense heat waves. Scientists predict global temperature increases from human-made greenhouse gases will continue. Severe weather damage will also increase and intensify.
What level of CO2 is harmful to humans?
The American Conference of Governmental Industrial Hygienists (ACGIH) recommends an 8- hour TWA Threshold Limit Value (TLV) of 5,000 ppm and a Ceiling exposure limit (not to be exceeded) of 30,000 ppm for a 10-minute period. A value of 40,000 is considered immediately dangerous to life and health(IDLH value).
