New electrocatalyst converts CO2 into ethanol, acetone, and n-butanol with high efficiency

Green Car Congress

Excess energy produced by photovoltaics and wind energy could be stored through the electrocatalytic production of fuels from CO 2. The electrocatalytic conversion of CO 2 using renewable energy could establish a climate-neutral, artificial carbon cycle. These could then be burned as needed. and Xiong, Y.

This startup is about to install bladeless rooftop wind turbines on box buildings

Baua Electric

Aeromine Technologies just closed a $9 million funding round, and it’s ready to scale up production of its bladeless rooftop wind turbines. Aeromine, launched in 2022, makes compact 50 kW or larger “wind harvesting platforms” that it mounts on the edge of a building’s roof. Specs are here.) Get started here. –ad*

MIT proof-of-concept demo of ionic wind propulsion for aircraft

Green Car Congress

MIT researchers have demonstrated that an aircraft with a 5-meter wingspan can sustain steady-level flight using ionic-wind propulsion. He expects that in the near-term, such ion wind propulsion systems could be used to fly less noisy drones. c, Architecture of the high-voltage power converter (HVPC). EAD airplane design.

MITEI study finds hydrogen-generated electricity is a cost-competitive candidate for backing up wind and solar

Green Car Congress

A team at MITEI (MIT Energy Initiative) has found that hydrogen-generated electricity can be a cost-competitive option for backing up wind and solar. California draws more than 20% of its electricity from solar and approximately 7% from wind, with more VRE coming online rapidly. —Drake Hernandez. —Emre Gençer.

ZF presents new e-drives for passenger cars and commercial vehicles

Green Car Congress

These include the compact design of the drives, power electronics, and a resource-saving use of materials, which also makes the production of the drives more sustainable. A new cooling concept and a new winding technology play the decisive role here. E-Motor Stator with new braided winding. New high voltage converter.

IIASA-led study proposes Underground Gravity Energy Storage as long-term energy storage solution for renewables

Green Car Congress

However, because sunshine and wind are inherently variable and inconsistent, finding ways to store energy in an accessible and efficient way is crucial. Renewable energy sources are central to the energy transition toward a more sustainable future. An open-access paper on the work is published in the journal Energies. Dabek, P.B., Brandão, R.,
