This new method to capture carbon is driven by geothermal energy

Posted by in categories: climatology, sustainability

Researchers from Ohio State University have developed an innovative method to capture carbon dioxide (CO2) directly from the atmosphere. Powered by geothermal energy, the team’s method poses a climate-friendly alternative to traditional carbon capture technologies. It highlights the synergy between Direct Air Carbon Dioxide Capture (DACC) technologies and renewable energies from beneath the Earth’s surface.

The approach, named Direct Air CO2 Capture with CO2 Utilization and Storage (DACCUS), promises a significant decrease in atmospheric CO2 levels, a major contributor to global warming.

Climate change primarily results from increased CO2 levels in the Earth’s atmosphere, largely due to human activities like burning fossil fuels for heat, electricity, and transportation.

Efficient and Sustainable Transplutonium Isotope Production: A New Diagnostic Approach

Posted by in categories: computing, military, nuclear energy, space, sustainability

In this study, a novel rapid diagnostic method was developed for optimizing the production of transplutonium isotope through high flux reactor irradiation. The proposed method was based on the concept of “Single Energy Interval Value (SEIV)” and “Energy Spectrum Total Value (ESTV)”, which significantly improved the production efficiency of isotopes such as 252Cf (by 15.08 times), 244Cm (by 65.20 times), 242Cm (by 11.98 times), and 238Pu (by 7.41 times). As a promising alternative to the traditional Monte Carlo burnup calculation method, this method offers a more efficient approach to evaluate radiation schemes and optimize the design parameters. The research discovery provides a theoretical basis for further refining the analysis of transplutonium isotope production, leading to more efficient and sustainable production methods. Future studies could focus on the implementation of energy spectrum conversion technology to further improve the optimal energy spectrum.

The production of transplutonium isotope, which are essential in numerous fields such as military and space technology, remains inefficient despite being produced through irradiation in a high flux reactor. Past studies on the optimization of transplutonium isotope production through irradiation in a high flux reactor have been limited by the computational complexity of traditional methods such as Monte Carlo burnup calculation. These limitations have hindered the refinement of the evaluation, screening, and optimization of the irradiation schemes. Hence, this research aimed to develop a rapid diagnostic method for evaluating radiation schemes that can improve the production efficiency of isotopes such as 252Cf, 244Cm, 242Cm, and 238Pu. The outcome of the study showed great potential in advancing the production of transplutonium isotope, which have numerous applications in fields such as military, energy, and space technology.

Electrification or hydrogen? Both have distinct roles in the European energy transition

Posted by in categories: climatology, economics, sustainability

A study, published in One Earth, is the first to analyze the interplay of electrification and hydrogen in EU climate neutrality scenarios at greater sectoral detail. The analysis shows higher potential for electrification and identifies a more confined deployment range for hydrogen-based energy than earlier studies.

“Previous research has shown that our power system can be transformed to renewable sources like wind and solar at low cost and low environmental impact. However, the next question is how this renewable electricity can be used to substitute in the buildings, industry and transport sectors. Our analysis shows that the direct use of electricity, for example, via and , is critical for a broad range of sectors, while the conversion of electricity to hydrogen is important only for few applications,” says Felix Schreyer, PIK scientist and lead author of the study.

Using the energy-economy model REMIND, PIK-scientists investigated plausible combinations of both strategies in EU energy system transformation pathways under different scenario assumptions.

Is this Rivian’s more affordable R2 electric SUV spotted in the wild?

Posted by in categories: sustainability, transportation

As we get closer to the official debut of Rivian’s more affordable R2, we are finally getting a better idea of what to expect. After teasing the model for the first time yesterday, Rivian’s R2 was reportedly spotted filming in downtown LA shortly after.

Rivian opened the R2 website yesterday, teasing the first look at the new EV in an intro video. The new EV will be revealed on March 7 at its new flagship Laguna showroom.

Although Rivian teased the new model leading up to its highly anticipated debut, we have yet to see what it looks like in full, until now. A patent filed by Rivian last month revealed a more compact electric SUV than the R1S with slightly smaller headlights.

Plastic-eating fungi thriving in man-made ‘plastisphere’ may help tackle global waste

Posted by in categories: materials, sustainability

Year 2023 😗 😁


A new study published in the Journal of Hazardous Materials by researchers at the Royal Botanic Gardens, Kew, and partners has identified a diverse microbiome of plastic-degrading fungi and bacteria in the coastal salt marshes of Jiangsu, China.

The international team of scientists counted a total of 184 fungal and 55 bacterial strains capable of breaking down polycaprolactone (PCL), a biodegradable polyester commonly used in the production of various polyurethanes. Of these, bacterial strains within the genera Jonesia and Streptomyces have the potential to further degrade other petroleum-based polymers—natural or synthetic chains of molecules bound together.

Ecosystem Under Siege: An Alien Invasion That Could Trigger Catastrophic Changes Is Underway Across North America

Posted by in categories: evolution, sustainability

An alien invasion capable of triggering catastrophic changes is underway across North America. At least 70 imported earthworm species have colonized the continent, and represent a largely overlooked threat to native ecosystems, according to a new study by researchers at Stanford University, Sorbonne University, and other institutions.

The analysis, recently published in the journal Nature Ecology & Evolution, provides the largest-ever database of such earthworms and warns of the need to better understand and manage the invaders in our midst.

“Earthworms tell the story of the Anthropocene, the age we live in,” said study senior author Elizabeth Hadly, the Paul S. and Billie Achilles Professor in Environmental Biology in the Stanford School of Humanities and Sciences. “It is a story of global homogenization of biodiversity by humans, which often leads to the decline of unique local species and the disruption of native ecosystem processes.”
