Synthetic, #Photosynthetic, and #Chemical Strategies to Enhance #Carbon #Dioxide Fixation by Supriyo Ray et al. C 2022, 8(1), 18; https://lnkd.in/dkUhDaG9 Current number of article views/citations: 5652/6 Abstract The present human population is more than three times what it was in 1950. With that, there is an increasing demand for the consumption of fossil fuels for various anthropogenic activities. This consumption is the major source of carbon dioxide emission causing greenhouse effects leading to global warming. The dependency on fossil fuels around the globe is such that it would be hard to move away from it any time soon. Hence, we must work on strategies to improve carbon dioxide fixation as we are making advancements in clean energy technology. This review explores the natural carbon dioxide fixation pathways in plants and various microorganisms and discusses their limitations and alternative strategies. It explains what necessitates the exploration of synthetic pathways and discusses strategies and matrices to consider while evaluating various pathways. This review also discusses the recent breakthroughs in the field of nanosciences that could accelerate chemical methods of carbon dioxide fixation.

Emissions of nitrous oxide, a greenhouse gas regarded as more potent than carbon dioxide or methane, have continued to rise over the past 40 years, a global study has found. The study, which involved nearly 60 researchers around the world as part of the Global Carbon Project, found that 10 million metric tons of nitrous oxides flowed into the atmosphere in 2020. “Agricultural emissions reached eight million metric tons in 2020, a 67 percent increase from the 4.8 million metric tons released in 1980,” the study lead institute Boston College said in a report on the research. Among the researchers contributing to the report was Dr Judith Rosentreter from Australia’s Southern Cross University. She said the findings were concerning. “We live in an era when greenhouse gas emissions must decline to reduce global warming,” said Dr Rosentreter. “We are alarmed to see that the growth rates of atmospheric nitrous oxide in 2021 and 2022 were more than 30 percent higher than the average rate of increase in the previous decade.” The study published this month in the Earth System Science Data journal found that agricultural production accounted for 74 percent of human-driven nitrous oxide (N2O) emissions in the 2010s. This was mainly due to the use of commercial fertilisers and animal waste on croplands. https://lnkd.in/g7NRDBWq #greenhousegases #envrionment #newsreel

It’s hoped there is some robust and solution-focused discussion to continue in this space. Unless there is a holistic and practical approach taken to all emissions, the journey to #netzero and #decarbonisation will be thwarted by vested interest. #renewables #regionsleadingtheway #futurefocus #resoursessector #cleancoal #sustainability #Agtech

🔥 Using the power of methane-eating microbes to reduce methane emissions? Is it possible? Yes, it is! Methane-eating microbes utilize a process that allows them to consume methane as their primary source of energy and carbon. These microbes are found in environments where methane concentrations are naturally high, such as wetlands, or where methane is a significant byproduct, like agricultural sites and landfills. The microbes oxidize methane into carbon dioxide, which, while still a greenhouse gas, is significantly less potent than methane in terms of global warming potential. The potential of this biotechnology could be a game-changer for industries like agriculture and energy, where methane release is substantial. By integrating these microbes into emission-heavy processes, we can make a significant impact on our planet's health. This is a brilliant example of how innovative science is leading the way in sustainable practices. #Sustainability #ClimateAction #Innovation #EnvironmentalScience #GreenTech

#CarbonCapture | 𝗖𝗮𝗽𝘁𝘂𝗿𝗶𝗻𝗴 𝗚𝗿𝗲𝗲𝗻𝗵𝗼𝘂𝘀𝗲 𝗚𝗮𝘀𝘀𝗲𝘀 𝘄𝗶𝘁𝗵 𝗧𝗵𝗲 𝗛𝗲𝗹𝗽 𝗼𝗳 𝗟𝗶𝗴𝗵𝘁 | Breakthrough research has been realized by Professor Maria Lukatskaya and her team at the Electrochemical Energy Systems at ETH Zürich, utilizing light-reactive molecules to capture CO2. This revolutionary concept involves modulating the acidity of a liquid triggered by light, drastically addressing the greenhouse gas problem by enabling capture of significant CO2 amounts from the atmosphere. Critically, this new technology disengages from the substantial energy demands of conventional carbon capture technologies. The energy necessary for carbon capture theoretically arises from our own Sun, and with the aid of developed solvents that enhance the stability of light-reactive molecules over an extended period, this research stands crucial in the effort to decelerate global warming and meet climate objectives. 👉 Learn more >> https://lnkd.in/gyiyKzkM 👉 Original publication >> https://lnkd.in/gZQxrYri 🇨🇭 Follow #ScienceSwitzerland for the latest news and emerging trends on Swiss science, technology, education, and innovation >> www.swissinnovation.org Follow us >> Science-Switzerland #Science | #Education | #Research | #Innovation

The need to protect the oceans is gaining momentum New electrochemical technology could de-acidify the oceans – and even remove carbon dioxide in the process Only 45 per cent of carbon dioxide emissions remain in the atmosphere; the remainder is absorbed through two cycles: 1) the biological carbon cycle stores CO2 in plant matter and soils, and 2) the aqueous carbon cycle absorbs CO2 from the atmosphere into the oceans. Each of these cycles accounts for 25 per cent and 30 per cent of emitted CO2, respectively. CO2 that dissolves in the oceans reacts to form chemicals that increase the acidity of the oceans. As the oceans acidify, millions of marine species and whole ecosystems — especially coral reefs — will be unable to adapt. The good news is it is possible to re-balance the pH of the oceans using a process called ocean alkalinity enhancement (OAE). What’s more, this rebalancing will also encourage additional CO2 to be absorbed from the atmosphere. By carefully and continually restoring the ocean’s alkalinity, ocean acidification and excess atmospheric CO2 concentrations can be tackled simultaneously. (Source:https://lnkd.in/ge-VUpju)

The indicators kept screaming and yet, human greed continued to push the world towards mass extinction with ever increasing speed.... "Greenhouse concentrations hit record highs in 2022, with real-time data in 2023 indicating a continued rise. Carbon dioxide levels have surged to 150% above pre-industrial levels. Public funding for oil, coal, and gas production and consumption more than doubled from 2021 to 2022 and tripled since 2015, hindering progress towards a net-zero transition. Ocean acidification is on the rise and will persist if CO2 emissions continue to climb. Species extinction risk is worsening, with a 12% decline in the aggregate Red List Index since 1993."

When power plants burn fossil fuels at high temperatures, nitrogen and oxygen molecules break apart and then recombine to form a class of compounds called nitrogen oxides, or NOx. These gases are major pollutants and contribute to—among other things—acid rain and global warming.
