Researchers fabricate cobalt copper catalysts for methane on metal-organic framework

Posted by in categories: chemistry, energy, sustainability, transportation

The world is highly dependent on fossil fuels to power its industry and transportation. These fossil fuels lead to excessive carbon dioxide emission, which contributes to global warming and ocean acidification. One way to reduce this excessive carbon dioxide emission that is harmful to the environment is through the electroreduction of carbon dioxide into value-added fuels or chemicals using renewable energy. The idea of using this technology to produce methane has attracted wide interest. However, researchers have had limited success in developing efficient catalysts for methane.

A Soochow University research team has now developed a simple strategy for creating cobalt copper alloy catalysts that deliver outstanding methane activity and selectivity in electrocatalytic carbon dioxide reduction. Their research is published in Nano Research.

Over the past 10 years, scientists have made notable progress in advancing their understanding of catalysts and applying the knowledge to their fabrication. But the catalysts that have been developed have not been satisfactory for use with methane, in terms of selectivity or current density. Despite the great insights scientists have gained, the strategies they have attempted in creating catalysts for methane are just too costly to be useful in practical applications.

Tyromer Builds Pilot Factory for Circular Rubber in Arnhem

Posted by in categories: economics, energy, sustainability, transportation

Canada-based Tyromer is building a pilot factory in Arnhem to bring its circular rubber products to the European market. Specializing in the devulcanization of rubber from scrap tires, Tyromer will fine-tune and exhibit its recycling technology at its new Dutch facility in order to sell the process to third parties. The company is one of the first in the Netherlands to give this hard-to-process residual product a high-quality new life, making it a valuable addition to the Dutch circular economy.

Located at Kleefse Waard Industrial Park (IPKW) in Arnhem, the factory is currently being set up. “We expect to be able to start early in the summer [of 2021],” said Jos van Son, managing director of Tyromer Europe. Tyromer will employ approximately 12 people in Arnhem.

“Tyromer has a unique solution to a major problem: mountains of car tire rubber that cannot be reused. Companies such as Tyromer, which have solutions for societal challenges with smart technologies, are a welcome addition to the East Netherlands ecosystem. The fact that Tyromer is establishing itself at IPKW, where many companies are involved with energy and circularity issues, is good news for the activity in our region,” added René Brama, investment manager of Tech at Oost NL.

Meet ‘Copernicus’: TAE’s planned billion-degree, hydrogen-boron nuclear fusion reactor

Posted by in categories: climatology, engineering, nuclear energy, sustainability

TAE’s latest backers include the likes of Google and Chevron

TAE has earned the backing of forward-thinking investors and, so far, has raised a total of $1.2 billion for its commercial fusion development thanks to a track record of exceeding milestones and performance capability. TAE’s mission is to provide a long-term solution to the world’s rapidly increasing electricity demand while ensuring global energy independence and security.

To that end, the company recently closed its Series G-2 financing round, in which it secured $250 million from investors in the energy, technology, and engineering sectors. By avoiding carbon and particulate emissions, TAE’s safe, non-radioactive method minimizes any negative effects on the environment or the effects of climate change.

Local renewable energy employment can fully replace US coal jobs nationwide

Posted by in categories: employment, energy, sustainability

Across the United States, local wind and solar jobs can fully replace the coal-plant jobs that will be lost as the nation’s power-generation system moves away from fossil fuels in the coming decades, according to a new University of Michigan study.

As of 2019, -fired directly employed nearly 80,000 workers at more than 250 plants in 43 U.S. states. The new U-M study quantifies—for the first time—the technical feasibility and costs of replacing those coal jobs with local wind and solar employment across the country.

The study, published online Aug. 10 in iScience, concludes that local wind and solar jobs can fill the electricity generation and employment gap, even if it’s required that all the new jobs are located within 50 miles of each retiring coal plant.

This oddly-shaped Finnish cabin was made with cross-laminated timber to withstand subarctic cold!

Posted by in categories: materials, sustainability

This cabin in the woods is an otherworldly, all-black, geometric structure built to provide cozy refuge even in harsh Finnish winters. It was designed for a California-based CEO who returned home to Finland with her family to be closer to her ancestral land so she could maintain it. The cabin is aptly named Meteorite based on its unique shape and is set in a clearing surrounded by spruce and birch trees. The cabin is made entirely from cross-laminated timber (CLT) which is a sustainable alternative to other construction materials.

Off-grid desalination system Wave2O is ready to quench the world’s thirst

Posted by in categories: security, sustainability

Water scarcity is a major global crisis that already affects every continent. Around 1.2 billion people, or almost one-fifth of the world’s population, lack access to safe drinking water. Desalination is the answer to long-term water security, but it’s also expensive, energy-intensive, and often inaccessible to isolated regions. This is why sustainable off-grid desalination systems powered by renewable energy are essential.

But thanks to the innovative microbial desalination cell (MDC) technology that follows a green, low-energy process with electro-active bacteria to desalinate and sterilize seawater, desalination is becoming a viable low-cost solution for water resources in many areas of the world and is putting an end to water scarcity even in isolated regions.

Now, researchers from the EU-funded W20 project have developed an off-grid innovative solution – the world’s first wave-driven desalination system – called Wave2O. The new system can be deployed quickly, operate completely off-grid, and supply large quantities of fresh water at a competitive cost. The technology uses the power of the ocean waves, a consistent and inexhaustible renewable energy source.

Thinking Huts intends to increase access to education.

Maggie Grout, who was born in a rural mountain village in China, was adopted rather young. “And I think that largely shaped my outlook through the rest of my life — knowing what poverty looks like, and how it impacts the opportunities you’re able to achieve in life. Having that allowed me to see more clearly what my purpose was in life — helping children gain access to education in underprivileged areas in the world,” she tells *IE* in an interview. Huts rely on additive manufacturing technologies to build sustainable schools. Recently, they built the first 3D-printed school in Madagascar.

Secrets of sustainable distributed-generation strategies

Posted by in categories: energy, policy, sustainability

The sad truth is that our electricity markets currently lack the ability to accept the vast amounts of renewable energy capacity to meet state targets and corporate commitments to procure clean energy. A study by Princeton University found that high-voltage transmission capacity would need to expand by 60% to meet clean energy targets, representing billions of dollars in needed utility upgrades.

However, we can avoid much of this need by siting renewable resources closer to where they are needed – at the distribution level of the grid. In order to do so, we will need to take several key steps to solve major system barriers to expanding renewable energy on the grid. The good news is that with some policy improvements – some major and some minor – renewable energy capacity at the distribution level can meet needs without the long lead time required for larger, utility-scale resources.

Soap molecule could help make alternative LED tech commercially viable

Posted by in categories: robotics/AI, solar power, sustainability

Adding a molecule normally used in detergent to an infrared LED could make devices that are easier to manufacture, require less energy and display richer colours than existing ones.

Solar cells and LEDs made from perovskite, a titanium and calcium crystal, have long held promise as being more efficient and easier to produce than commonly used silicon-based devices, but making them both stable and efficient enough to rival silicon’s commercial success has proved difficult.
