The E-fuel project of VTT and partners has developed a concept for producing electrofuel from green hydrogen and carbon dioxide using a combination of different methods. On Nov. 21, this paraffinic E-fuel was tested for the first time in Finland on a diesel-powered tractor at AGCO Power’s Linnavuori factory in Nokia. The new electrofuel is also suitable for vehicles that are difficult to electrify, and is therefore an important step in the development of sustainable fuel solutions.

Global climate goals require drastic changes in all aspects of life. Carbon capture and utilization are key to moving towards sustainable fuel solutions for transport...

In nationwide projections, elderly and Black adults are most at risk for cardiovascular death due to extreme heat, finds a new study. Cardiovascular deaths from extreme heat in the U.S. may more than double by the middle of the century. Without reductions in greenhouse gas emissions, that number could even triple, according to new research published today in the American Heart Association’s flagship journal Circulation.

“Climate change and its many manifestations will play an increasingly important role on the health of communities around the world in the coming decades, ” said lead study author Sameed Khatana, M.D., M.P.H...

MXene and MBene compounds hold promise for new technologies to combat climate change. Some of the thinnest materials known to humankind — MXene and MBene compounds — may provide solutions to scientists in their quest to curb the effects of global warming. These substances are only a few atoms thick, making them two-dimensional. Because of their large surface area, the materials have the potential to absorb CO2 molecules from the atmosphere, which could help reduce the harmful effects of climate change by safely sequestering carbon dioxide, according to a review study.

Achieving photochemical upconversion in a solid state is a step closer to reality, thanks to a new technique that could unlock vital innovations in renewable energy, water purification and advanced healthcare.

Exciton Science researchers based at UNSW Sydney have demonstrated that a key stage in the upconversion process can be achieved in the solid state, making it more likely that a functioning device can be manufactured at commercial scale. Possible applications include hydrogen catalysis and solar energy generation.

Their work has been published in the high-impact journal ACS Energy Letters and is likely to drive major changes in the approach of scientists around the world researching this challenging but potentially transformational field.

Professor Tim Schmidt of UNSW Sy...
