The UN climate report pins hopes on carbon removal technologies that barely exist

Posted by in categories: climatology, sustainability

The model used to create the most optimistic scenario in the report, which limits warming to 1.5 ˚C, assumes the world will figure out ways to remove about 5 billion tons of carbon dioxide a year by midcentury and 17 billion by 2100. (The scenario is known as SSP1-1.9, and those figures are based on an analysis of earlier data by Zeke Hausfather, a climate scientist at the Breakthrough Institute and contributing author on the UN assessment.)

The UN’s long-awaited climate report, released on Monday, offered a stark reminder that removing massive amounts of carbon dioxide from the atmosphere will be essential to prevent the gravest dangers of global warming. But it also underscored that the necessary technologies barely exist—and will be tremendously difficult to deploy.

Global temperatures will continue to rise through midcentury no matter what we do at this point, according to the first installment of the Intergovernmental Panel on Climate Change’s sixth assessment report. How much hotter it gets, however, will depend on how rapidly we cut emissions and how quickly we scale up ways of sucking carbon dioxide out of the air.

Carbon-capturing Celour paint allows anyone to “participate in CO2 removal in their daily lives”

Posted by in categories: materials, sustainability

This could prove helpful. 😀

Design graduate Kukbong Kim has developed a paint made from demolished concrete that is capable of absorbing 20 per cent of its weight in carbon.

Called Celour, the paint can sequester 27 grams of CO2 for every 135 grams of paint used.

Vortex Bladeless wind turbines generate electricity from the vibration

Posted by in categories: solar power, sustainability

Wind farms certainly allow for the production of clean energy. Although they are 100% renewable, they still have problems. They have high costs, disfigure the landscape, produce noise pollution, and above all, have a heavy impact on fauna, and in particular on birds.

The Spanish startup Vortex Bladeless has developed a bladeless turbine that can revolutionize wind energy, especially at the household level, and become the alternative to solar panels. The design of the Spanish firm has already received the approval of Norway’s state energy company, Equinor.

Caltech’s New Space-Based Solar Project Could Power Our Entire Planet /

Posted by in categories: solar power, space, sustainability

It’s the stuff of science fiction: Solar panels in space that beam power directly to Earth equipping the planet with clean renewable and affordable energy. Yet, it could soon be reality.

Caltech has just received $100 million in funding for their Space Solar Power Project (SSPP). The project is described by Caltech as: “Collecting solar power in space and transmitting the energy wirelessly to Earth through microwaves enables terrestrial power availability unaffected by weather or time of day. Solar power could be continuously available anywhere on earth.”

“This ambitious project is a transformative approach to large-scale solar energy harvesting for the Earth that overcomes this intermittency and the need for energy storage,” said SSPP researcher Harry Atwater in the Caltech press release on the matter.

Technology is shaping the future of food but practices rooted in tradition could still have a role to play

Posted by in categories: business, food, sustainability

Discussions about how and where we produce food are set to continue for a long time to come as businesses, governments and citizens try to find ways to create a sustainable system that meets the needs of everyone.

It’s perhaps no surprise then that some of the topics covered above are starting to generate interest among the investment community.

Speaking to CNBC’s “Squawk Box Europe” in June, Morgan Stanley’s global head of sustainability research, Jessica Alsford, highlighted this shift.

Rust? Trains? Why clean energy is turning to exotic ideas to fix its storage problem

Posted by in categories: energy, sustainability, transportation

Energy storage ideas.

Mateo Jaramillo sees the future of renewable energy in thousands of iron pellets rusting away in a laboratory in Somerville, Massachusetts.

Jaramillo is chief executive of Form Energy, a company that recently announced what it says is a breakthrough in a global race: how to store renewable energy for long periods of time.

U.S. Navy is developing a solar-powered plane that can fly for 90 days straight

Posted by in categories: solar power, sustainability, transportation

The aircraft, evocatively called Skydweller and built by a U.S.-Spanish aerospace firm Skydweller Aero, could help the Navy keep a watchful eye on the surrounding seas while escorting ships months at a time or act as a communications relay platform. The company was awarded a $5 million contract by the U.S. Navy to develop the aircraft.

To stay airborne for so long, the pilotless craft would have 2900sq ft of solar cells on its wings.

Using graphene foam to filter toxins from drinking water

Posted by in categories: chemistry, engineering, health, nuclear energy, sustainability

Some kinds of water pollution, such as algal blooms and plastics that foul rivers, lakes, and marine environments, lie in plain sight. But other contaminants are not so readily apparent, which makes their impact potentially more dangerous. Among these invisible substances is uranium. Leaching into water resources from mining operations, nuclear waste sites, or from natural subterranean deposits, the element can now be found flowing out of taps worldwide.

In the United States alone, “many areas are affected by uranium contamination, including the High Plains and Central Valley aquifers, which supply drinking water to 6 million people,” says Ahmed Sami Helal, a postdoc in the Department of Nuclear Science and Engineering. This contamination poses a near and present danger. “Even small concentrations are bad for human health,” says Ju Li, the Battelle Energy Alliance Professor of Nuclear Science and Engineering and professor of materials science and engineering.

Now, a team led by Li has devised a highly efficient method for removing uranium from drinking water. Applying an electric charge to graphene oxide foam, the researchers can capture uranium in solution, which precipitates out as a condensed solid crystal. The foam may be reused up to seven times without losing its electrochemical properties. “Within hours, our process can purify a large quantity of drinking water below the EPA limit for uranium,” says Li.
