A fully-electric 10,000 ton container ship has begun service equipped with over 50,000 kWh in batteries
Posted by Shailesh Prasad in categories: sustainability, transportation
Chinese state-owned company COSCO Shipping has launched what it calls the “world’s largest” river-to-sea electric container ship. The Green Water 1 is a 10,000-ton+ fully electric vessel that sets a new benchmark in sustainability in the marine logistics industry.
China Ocean Shipping (Group) Company, or COSCO for short, is a state-owned multinational conglomerate headquartered in Shanghai specializing in marine transport. Not to be confused with Costco, COSCO Shipping was founded as a subsidiary in 2016 following an approved merger between COSCO and China Shipping.
The COSCO Group is the largest liner carrier in China, transporting hundreds of container vessels daily while also providing ships to Chinese automakers to help them export their electric vehicles to new markets overseas, including Europe.

Marriage of synthetic biology and 3D printing produces programmable living materials
Posted by Dan Breeden in categories: 3D printing, bioengineering, biological, genetics, sustainability
Scientists are harnessing cells to make new types of materials that can grow, repair themselves and even respond to their environment. These solid “engineered living materials” are made by embedding cells in an inanimate matrix that’s formed in a desired shape. Now, researchers report in ACS Central Science that they have 3D printed a bioink containing plant cells that were then genetically modified, producing programmable materials. Applications could someday include biomanufacturing and sustainable construction.

China battery price war could soon make electric cars cheaper. Here’s how
Posted by Shailesh Prasad in categories: energy, sustainability, transportation
The main cost of an electric vehicle (EV) is its battery. The high cost of energy-dense batteries has meant EVs have long been more expensive than their fossil fuel equivalents.
But this could change faster than we thought. The world’s largest maker of batteries for electric cars, China’s CATL, claims it will slash the cost of its batteries by up to 50% this year, as a price war kicks off with the second largest maker in China, BYD subsidiary FinDreams.
What’s behind this? After the electric vehicle industry experienced a huge surge in 2022, it has hit headwinds. It ramped up faster than demand, triggering efforts to cut costs.

Scientists Say New Material Can Suck Carbon Out of Atmosphere Faster Than Trees
Posted by Shailesh Prasad in categories: climatology, computing, sustainability
A team of scientists in the United Kingdom say they’ve discovered a porous material that has the potential to store large quantities of greenhouse gases, making it a possible new tool in the arsenal to fight climate change.
The scientists detailed how they used computational models to develop this material in a newly published paper in the journal Nature Synthesis, arguing that certain features of the structure could make it excellent storage for carbon dioxide and sulphur hexafluoride, another powerful greenhouse gas.
“This is an exciting discovery because we need new porous materials to help solve society’s biggest challenges,” engineering professor Marc Little from Edinburgh’s Heriot-Watt University said in a statement about the research.

Tesla Megapack to power new massive record-breaking 1.3 GWh battery system
Posted by Shailesh Prasad in category: sustainability
Tesla Megapack has been selected to power a massive new record-breaking 13 GWh battery system from Neoen in Australia.
This project is the second stage of the Collie Battery project, which is named after a town in Western Australia where the project is located.
As we previously reported, France’s Neoen is already building the first stage with Tesla Megapack 2XLs.

Discovery of uranium-contaminated soil purification material without secondary environmental pollution
Posted by Dan Breeden in categories: chemistry, economics, engineering, health, nanotechnology, nuclear energy, sustainability
Nuclear energy has long been regarded as a next-generation energy source, and major countries around the world are competing to secure cutting-edge technologies by leveraging the high economic efficiency and sustainability of nuclear power. However, uranium, which is essential for nuclear power generation, has serious implications for both soil ecosystems and human health.
Despite being a key radioactive material, uranium poses significant health risks due to its chemical toxicity to the kidneys, bones, and cells. As a result, both the U.S. Environmental Protection Agency and the World Health Organization recommend allowing and advocating for uranium concentrations in wastewater to be below 30 μg/L.
The Korea Institute of Civil Engineering and Building Technology (KICT) has conducted research on a nano-material-based adsorption process to efficiently remove uranium wastewater extracted from actual radioactive-contaminated soil. They have also proposed its applicability to prevent secondary environmental pollutions.
