Wärtsilä hybrid propulsion system with methanol engine to power four SAL heavy lift vessels; wind farm installations

Green Car Congress

The hybrid system also includes Energy Storage, a PTO/PTI generator and motor, a multidrive converter, and the Wärtsilä Energy Management System for controlling and optimiszing the hybrid operations. The ships are scheduled for delivery in 2025 and will be used mainly to support wind farm installations.

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. The fuselage of the plane holds a stack of lithium-polymer batteries.

Wind-to-Hydrogen Tech Goes to Sea

Cars That Think

Wind and solar parks produce a large portion of their energy. Then, as now, wind farms are operating off the world’s coasts—but not all of these offshore sites are connected to the mainland via underwater power cables. Some of the wind farms instead sit in clusters more than 100 kilometers out at sea.

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*

PCC SE and Landsvirkjun to convert silicon metal plant CO2 emissions to methanol

Green Car Congress

Furthermore, the nature of silicon metals is such that without it, there would not be the performance of solar power in the European Union, nor innovative solutions such as next-generation battery anodes, which are key to higher capacities. Landsvirkjun generates energy from renewable sources: hydro, geothermal and wind.

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. Low- and zero-carbon alternatives to greenhouse-gas emitting peaker plants are in development, such as arrays of lithium-ion batteries and hydrogen power generation. —Emre Gençer.

Anglo American unveils prototype 2MW hydrogen-battery hybrid mine haul truck

Green Car Congress

The 2MW hydrogen-battery hybrid truck, generating more power than its diesel predecessor and capable of carrying a 290-tonne payload, is part of Anglo American’s nuGen Zero Emission Haulage Solution (ZEHS). Design and implement a software solution to safely manage power and energy between the fuel cells, batteries, and vehicle drivetrain.
