Increasing Deep Water Oxygen Levels by “Mixing Down” Oxygen

Posted by in categories: climatology, computing, health, sustainability

With climate change warming the oceans, this results in drastic consequences for marine life in deep water environments, but can steps be taken to help mitigate these effects? This is what a recent study published in Nature Communications hopes to address as a team of researchers from the United Kingdom investigated how “mixing down” oxygen levels in the ocean could help contribute to a more suitable environment for deep sea life. This study holds the potential to help scientists, conservationists, legislators, and the public better understand the steps that can be taken to mitigate the long-term effects of climate change.

Decreasing oxygen levels in the ocean is a natural phenomenon, but climate change has been predicted to accelerate this process, which could lead to massive decreases in oxygen levels in deep water environments and pose catastrophic consequences for marine life. For the study, the researchers used new methods that combine ocean water data from the Celtic Sea and computer models to ascertain how deep water oxygen levels could be replenished during the warmer summer months. In the end, they determined that summertime storms can result in the “mixing down” of oxygen and decrease this oxygen loss by almost half, which also shows promise for putting floating wind farms in the northern North Sea and Celtic Sea to assist in this process.

“There is growing concern for the health of our coastal oceans as the climate warms because warmer water holds less oxygen,” said Dr. Tom Rippeth, who is a Professor of Physical Oceanography at Bangor University and lead author of the study. “Living creatures in the ocean are reliant on oxygen to survive in the same way as animals on land are. Oxygen is also used up as rotting matter decomposes in the depths of the ocean. This creates a summer oxygen deficit in the deep seas around the UK. Unfortunately, as our climate warms, this deficit is forecast to grow.”

Chinese automaker launches world’s first EV with ‘semi-solid-state’ battery

Posted by in categories: internet, sustainability

In a promising step towards the evolution of next-generation electric vehicles (EV), Chinese car maker IM Motors has launched a car that features a version of solid-state batteries.

The battery pack, dubbed “Lightyear” by IM, is the primary power source for the company’s flagship L6 Lightyear Max, priced at approximately ¥330,000 (equivalent to US$45,600).

Tesla is laying off more than 10% of its workforce, memo shows

Posted by in categories: Elon Musk, sustainability, transportation

Tesla is the latest major company to lay off employees.

The company is eliminating “more than 10%” of staff globally, according to an internal memo sent by Elon Musk on Sunday, which was seen by Business Insider. The layoffs have come shortly after the carmaker posted lackluster delivery numbers.

Musk wrote in the email: “There is nothing I hate more, but it must be done. This will enable us to be lean, innovative and hungry for the next growth cycle.”

Scientists develop innovative technique to transform plastic waste into powerful clean fuel: ‘[It] could be produced for free’

Posted by in categories: sustainability, transportation

Battery–electric vehicles have become ubiquitous as more people have realized how much less pollution they produce than traditional gas-powered cars. But another type of planet-friendly vehicle, the hydrogen car, has yet to catch on, for a few different reasons.

Now, a new technique developed by researchers at Rice University in Texas may provide the key to making hydrogen cars — and hydrogen fuel as a whole — more viable.

Giant battery to be installed underground as deep as Empire State Building is tall: ‘It’s a massive amount of storage’

Posted by in categories: energy, sustainability

A small town in central Utah is set to be the home of a new underground “battery” that will store hydrogen as a clean energy source.

According to The New York Times, developers are creating two caverns as deep as the Empire State Building is tall from a geological salt formation near Delta, Utah. These caverns, which are expected to be complete next year, will be able to store hydrogen gas.

Cornell researchers develop lithium EV battery that charges under 5 mins

Posted by in categories: engineering, sustainability, transportation

A research team led by Lynden Archer, professor and dean of Cornell Engineering, has developed a new lithium battery that can charge in as little as five minutes. This could help address anxiety associated with the charging time of electric vehicles (EVs) and increase their adoption.

In their bid to reduce emissions from transportation, countries worldwide are looking to electrify various modes of transport. Road-based transport such as cars, buses, and trucks have led this transformation, aiming to even ban the sale of fossil fuel-powered cars in the next decade.

South Korea to tackle CO2 & saltwater with clever tech

Posted by in categories: innovation, sustainability

An integrated plant that will remove 50,000 tonnes of carbon dioxide every year and create new freshwater from salty seawater is planned in the Daesan Industrial Complex in South Korea. When ready, this will be the world’s first such facility.

As countries work on their promises to go carbon neutral in a few decades, there is a strong push for innovative approaches that capture and utilize carbon. Carbon capture facilities work onsite to help reduce the release of carbon into the atmosphere. In contrast, direct air capture (DAC) technology focuses on removing the released carbon dioxide from the atmosphere.

North America just got a new recycled Li-ion battery materials plant

Posted by in categories: materials, sustainability

Green Li-ion has launched a commercial-scale plant to process unsorted battery waste, or “black mass,” from used lithium-ion batteries.

Within an existing recycling facility in Atoka, Oklahoma, the plant will produce sustainable, battery-grade cathode precursor, lithium, and anode materials – closing the EV recycling loop with the production done all in one plant.

The current recycling process for spent lithium-ion batteries in North America includes sorting batteries before shredding, which are then processed into black mass and further into sulfates. The material is then exported overseas, most often to China and South Korea, for further processing.

Tesla releases more details on Powerwall 3, confirms cheaper stack coming

Posted by in category: sustainability

Tesla has released more details about Powerwall 3, its new generation home energy storage system, and there’s some more good news.

Electrek first reported that Tesla started Powerwall 3 installations in the US despite having yet to launch the product on its website officially back in September.

As we previously reported, the biggest difference with the Powerwall 3 is a higher power output of 11.5 KW continuous and an integrated solar inverter.

The proton engine Einstein predicted, created for the first time: challenges the laws of the universe and makes cars sustainable

Posted by in categories: nuclear energy, physics, space, sustainability

Do you know what they’ve discovered? This is the proton engine that Einstein predicted decades ago and that, for the first time, they’ve managed to materialize. The best part? It challenges even the laws of physics and the universe, and it’s going to decarbonize transportation.

Nuclear fusion has long been a sought-after but elusive goal for science. It involves joining atomic nuclei to release energy, the same process that occurs in the Sun and other stars. In fact, it’s a process similar to what we saw two weeks ago with the plasma engine.

Unlike nuclear fission used in current nuclear power plants—which, remember, we are highly critical of due to its lack of being an eco-friendly or renewable option—fusion offers the promise of a virtually inexhaustible and clean energy source.
