Michigan finalizing plan to build first-ever wireless charging road for electric cars

Posted by in categories: sustainability, transportation

LANSING, Mich. — Michigan has finalized a contract to build the country’s first wireless charging road system in Detroit, the state announced Tuesday.

The Michigan Department of Transportation awarded the project to Electreon, an electric vehicle solutions firm that will construct a 1-mile stretch of road open to the public and capable of charging battery-powered cars and trucks in real time.

The road where it will be built hasn’t been selected yet, the state said. It will be located somewhere in Detroit.

Electreon, Ford Developing In-Road Charging System Near Mobility Tech Hub

Posted by in categories: economics, robotics/AI, sustainability, transportation

Ford Motor Co. is working with Israeli startup Electreon to construct a mile-long road near Detroit’s Michigan Central Terminal that will charge electric vehicles as they travel on it. The pilot program will deploy an inductive in-road charging system in partnership with the Michigan Department of Transportation, the Michigan Office of Future Mobility and Electrification and the Michigan Economic Development Corp. “As we aim to lead the future of mobility and electrification by boosting electric vehicle production and lowering consumer costs, a wireless in-road charging system is the next piece to the puzzle for sustainability,” Michigan Governor Gretchen Whitmer said in a statement. Also supporting the project, which is expected to be operational in 2023, are Next Energy and the Jacobs Engineering Group. Ford purchased the long-abandoned train station and is converting it to be the hub of what it calls its “mobility innovation district,” where software developers and others will focus on making electrified and autonomous transportation more practical.

Stelco Enters EV Battery Recycling Market Through Primobius

Posted by in categories: engineering, sustainability, transportation

Stelco, which is a steelmaker producing flat-rolled, cold-rolled, and hot-rolled steel products, has announced that it is entering the electric vehicle battery recycling market through agreements with Primobius GmbH.

The company executed binding licensing and option agreements with Primobius to commercialize Primobius’ EV battery recycling and processing technologies in North America. Under the agreement, Stelco will be able to advance commercial lithium-ion battery feedstock sourcing agreements. It will also allow the company to begin the engineering and approval processes. The agreement enables Primobius the right to acquire between 25% and 50% equity in Stelco’s wholly-owned subsidiary.

The proposed Lake Erie Works refinery will enable Stelco to join the ranks of lithium-ion battery recycling leaders in North America. The integrated shredding and hydrometallurgical refinery will produce up to 18,400 net tons per year of nickel, manganese, and cobalt sulfates, and lithium hydroxide and carbonate. It’s expected to generate up to 40,000 net tons per year of scrap steel that Stelco will recycle into its steelmaking operations.

Abandoned Coal Mines Could Be Transformed Into Geothermal Greenhouses

“They’re almost perfect,” she said.

Because the farms are not dependent upon the seasons they can acheive up to 10 crop cycles per year as opposed to 1 to 2 cycles in normal agriculture, producing up to 80 tons of food annually.

Because of this, one indoor acre is equivalent to 4–6 outdoor acres, Riffat says.

“Game-changing” anode exchange membrane promises cheaper green hydrogen

Posted by in categories: energy, sustainability

Electrolysis is a key component of the cost of green hydrogen, and a Korean team says it’s made a huge breakthrough with an anion exchange membrane that’s not only much cheaper than current proton exchange tech, but offers some 20 percent better performance.

Electrolysis is the process of splitting water into hydrogen and oxygen, and when powered by renewable energy, it’s shaping up to be a key step in the production of green hydrogen. Green hydrogen is set to play a substantial role in the race to zero emissions, offering a high energy density that makes it an attractive option in several hard-to-decarbonize activities where batteries just don’t make sense.

Typically, electrolyzers use proton exchange membranes (PEMs), in which an anode and a cathode in an electrolyte material are separated by a membrane designed to allow positively-charged hydrogen ions to pass through as they’re attracted by the cathode. Here they combine with electrons to form hydrogen gas, which is collected, and oxygen is released at the anode.

BYD introduces a unique looking electric school bus for the US with vehicle-to-grid capabilities

Posted by in categories: education, sustainability, transportation

Chinese mobility manufacturer BYD has introduced its new “Type A” electric school bus to transport up to thirty US students at a time. Furthermore, the new zero-emission bus is ADA capable up to 800 lbs and can travel 140 miles on a single charge. What may be most appealing to school districts, however, is the vehicle-to-grid (V2G) capabilities BYD’s Type A school bus will provide.

BYD is an acronym for “Build Your Dreams,” a motto the Chinese automaker has followed since 1995 when it was founded. BYD Auto, the subsidiary of BYD Co. Ltd. will be celebrating its 20th anniversary next year, as it sits as one of the largest auto manufacturers in China. In 2021, BYD produced over 320,000 BEVs, second in the country only to SAIC.

In addition to manufacturing unique “blade” EV batteries, BYD Auto develops and manufactures electric cars, buses, trucks, bicycles, and even forklifts – under its own monicker as well as for other OEMs like Toyota.

Renewable energy from space? One student hopes to harness it

Posted by in categories: education, solar power, space, sustainability

While renewable energy sources like wind and solar have become more common across the United States, fossil fuels remain the main source of energy. According to the U.S. Information Administration’s (EIA) International Energy Outlook 2021 (IEO2021), the global supply of fossil fuels and biofuels is expected to adequately meet global demands for liquid fuel through 2050. Renewable energy technologies have improved to become more efficient and less costly, however most renewable energies are unable to provide a constant supply of energy.

This issue inspired Shriya Tailor, a middle school student from Duluth, Georgia, to find a constant renewable energy supply that created energy at all hours of the day and in any weather condition.

She looked to space for this solution, leading her to design a prototype for a “Solar Energy Station.” Shriya says the station, made of solar cells, would need to be around 50 miles away from earth for the energy waves to be transmitted back to earth via electromagnetic fields, then collected by an antenna and converted back to electricity. Consisting of a small solar panel, switching circuit, and transmitting and receiving coils, Shriya’s prototype allowed her to test her process here on earth.

Astronomers Suggest a Surprising New Way to Detect Alien Megastructures

Posted by in categories: alien life, satellites, solar power, sustainability

How do you power a super advanced alien civilization? Soak up a star.

We harness the power of the sun using solar panels. What if you were to scale this idea to astronomical proportions? Surround an entire star with solar-collecting structures or satellites to power your sprawling alien galactic empire. Such massive structures are known as megastructures—in this case a “Dyson sphere.” We are already trying to detect possible megastructures in space using the dimming of a star and the glow of megastructure components in infrared light. But recent research provides a new detection method—a Dyson sphere may cause its host star to swell and cool.
