Beaming Clean Energy From Space — Caltech’s “Extraordinary and Unprecedented Project”

Posted by in categories: engineering, solar power, space travel, sustainability

Technology capable of collecting solar power in space and beaming it to Earth to provide a global supply of clean and affordable energy was once considered science fiction. Now it is moving closer to reality. Through the Space-based Solar Power Project (SSPP), a team of California Institute of Technology (Caltech) researchers is working to deploy a constellation of modular spacecraft that collect sunlight, transform it into electricity, then wirelessly transmit that electricity wherever it is needed. They could even send it to places that currently have no access to reliable power.

“This is an extraordinary and unprecedented project,” says Harry Atwater, an SSPP researcher and Otis Booth Leadership Chair of Caltech’s Division of Engineering and Applied Science. “It exemplifies the boldness and ambition needed to address one of the most significant challenges of our time, providing clean and affordable energy to the world.”

China: Lithium batteries may soon power ‘world’s largest fleet’ of submarines

Posted by in categories: sustainability, transportation

With an estimated 60 to 70 vessels, China allegedly possesses the largest fleet of conventional submarines in the world.

The Chinese Navy could finally use lithium technology to replace the lead-acid batteries that are now used in its fleet of conventional submarines.

Since lithium batteries had a higher risk of catching fire or exploding, the navy was hesitant to replace the submarine fleet’s current batteries with them.

Solar panels: How new materials can make them cheaper and better than ever

Posted by in categories: mobile phones, solar power, sustainability

Transitioning away from fossil fuels.

The cost of turning sunlight into electricity has fallen more than 90 percent over the last decade. Solar is now the cheapest form of newly built energy generation. Job done? Not quite. Right now, solar works well at cost-competitive prices and can help us cut emissions significantly. But with less than five percent of the world’s electricity delivered by solar, we are just at the start.

The solar panels of 2022 are like the chunky mobile phones of the 1990s. Much more is possible with the same underlying technology.

Revolutionary technique to generate hydrogen more efficiently from water

Posted by in categories: chemistry, computing, engineering, sustainability

A team of researchers from the National University of Singapore (NUS) have made a serendipitous scientific discovery that could potentially revolutionize the way water is broken down to release hydrogen gas—an element crucial to many industrial processes.

The team, led by Associate Professor Xue Jun Min, Dr. Wang Xiaopeng and Dr. Vincent Lee Wee Siang from the Department of Materials Science and Engineering under the NUS College of Design and Engineering (NUS CDE), found that light can trigger a new mechanism in a catalytic material used extensively in , where water is broken down into and oxygen. The result is a more energy-efficient method of obtaining hydrogen.

This breakthrough was achieved in collaboration with Dr. Xi Shibo from the Institute of Sustainability for Chemicals, Energy and Environment under the Agency for Science, Technology and Research (A*STAR); Dr. Yu Zhigen from the Institute of High Performance Computing under A*STAR; and Dr. Wang Hao from the Department of Mechanical Engineering under the NUS CDE.

Penguin feathers may be secret to effective anti-icing technology

Posted by in categories: chemistry, drones, energy, engineering, sustainability

Ice buildup on powerlines and electric towers brought the northern US and southern Canada to a standstill during the Great Ice Storm of 1998, leaving many in the cold and dark for days and even weeks. Whether it is on wind turbines, electric towers, drones, or airplane wings, dealing with ice buildup typically depends on techniques that are time consuming, costly and/or use a lot of energy, along with various chemicals. But, by looking to nature, McGill researchers believe that they have found a promising new way of dealing with the problem. Their inspiration came from the wings of Gentoo penguins who swim in the ice-cold waters of the south polar region, with pelts that remain ice-free even when the outer surface temperature is well below freezing.

We initially explored the qualities of the lotus leaf, which is very good at shedding water but proved less effective at shedding ice,” said Anne Kietzig, who has been looking for a solution for close to a decade. She is an associate professor in Chemical Engineering at McGill and the director of the Biomimetic Surface Engineering Laboratory. “It was only when we started investigating the qualities of penguin feathers that we discovered a material found in nature that was able to shed both water and ice.”

‘Wind Challenger’: World’s first partially wind-powered cargo ship successfully sailed

Posted by in categories: energy, sustainability, transportation

It is the first coal carrier to be powered by hard sail wind power propulsion technology.

The world’s first partly wind-powered bulk carrier ship sailed to the Port of Newcastle on its maiden voyage this week. The Japanese shipping company Mitsui O.S.K. Lines (MOL), which delivered the 100,422 dwt (dead-weight tonnage) bulker on October 7, 2022, sailed to Newcastle on Monday, reported Offshore Energy.

2D nanoconfinement strategy enhances oxygen evolution performances

Posted by in categories: chemistry, energy, engineering, physics, sustainability

Prof. Zhang Tao’s group at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS), in collaboration with Prof. Hou Yang from Zhejiang University and Prof. Xiao Jianping from the Dalian Institute of Chemical Physics of CAS, proposed a novel two-dimensional (2D) nanoconfinement strategy to strongly enhance the oxygen evolution reaction (OER) activity of low-conductivity metal-organic frameworks (MOFs). Results were published in Nature Communications.

The development of high-efficiency electrocatalysts for the electrochemical conversion of water to generate environmentally friendly and sustainable hydrogen energy has drawn tremendous attention for decades.

Despite the crucial role the OER plays in water splitting, OER at the anode requires a relatively high thermodynamic potential to accelerate water splitting kinetics. Thanks to the large surface area, tunable porosity, diverse compositions and metal centers, MOFs have emerged as promising candidates for efficient OER electrocatalysts. However, the intrinsically poor conductivity of the most MOFs seriously impede their .
