Green ammonia could decarbonize 60% of global shipping when offered at just 10 regional fuel ports      (via sciencedaily.com)     Original source 

A study has found that green ammonia could be used to fulfill the fuel demands of over 60% of global shipping by targeting just the top 10 regional fuel ports. Researchers looked at the production costs of ammonia which are similar to very low sulphur fuels, and concluded that the fuel could be a viable option to help decarbonize international shipping by 2050.

High-performance stretchable solar cells      (via sciencedaily.com)     Original source 

Engineers have succeeded in implementing a stretchable organic solar cell by applying a newly developed polymer material that demonstrated the world's highest photovoltaic conversion efficiency (19%) while functioning even when stretched for more than 40% of its original state. This new conductive polymer has high photovoltaic properties that can be stretched like rubber. The newly developed polymer is expected to play a role as a power source for next-generation wearable electronic devices.

Conflict in full swing: Forest bats avoid large areas around fast-moving wind turbines      (via sciencedaily.com)     Original source 

Not only do many bats die at wind turbines, the turbines also displace some species from their habitats over large areas. When the turbines are in operation at relatively high wind speeds, the activity of bat species that hunt in structurally dense habitats such as forests drops by almost 80 per cent within a radius of 80 to 450 meters around the turbine.

New material allows for better hydrogen-based batteries and fuel cells      (via sciencedaily.com)     Original source 

Researchers have developed a solid electrolyte for transporting hydride ions at room temperature. This breakthrough means that the full advantages of hydrogen-based solid-state batteries and fuel cells can be had without the need for constant hydration. This will reduce their complexity and cost, which is essential for advancing towards a practical hydrogen-based energy economy.

The solar forest      (via sciencedaily.com)     Original source 

What would be the most effective use of a certain plot of land in terms of the climate crisis: planting a forest, which is a natural means of absorbing carbon dioxide from the atmosphere, or erecting fields of solar panels, which reduce the emission of carbon dioxide into the atmosphere? This dilemma has long been debated by decision-makers around the world. Now, for the first time -- based on findings from arid areas and on comprehensive measurements of the energy flow exchanged between the ground and the atmosphere -- we may have an answer to this question.

Why the long face? Scientists solve a major puzzle in mammal skull shape evolution      (via sciencedaily.com)     Original source 

Horses have developed long faces simply 'because they can,' a team of evolutionary biologists say. In a major review of how mammalian heads evolve, scientists found that adaptations to feeding explain why large species of mammals often have much longer faces compared to smaller closely related species -- a pattern referred to as Craniofacial Evolutionary Allometry (CREA).
