Argonne study finds rare earth supply disruptions can have long-range impacts

Green Car Congress

Disruptions to this supply can have wide-ranging consequences, but the understanding of how those disruptions play out in global markets is limited. Rare earth elements are essential to many emerging technologies, including those that support a clean energy future. Causes of supply disruptions. Riddle et al.

S&P Global: looming shortfalls in copper supply will short-circuit net-zero goals absent significant new supply

Green Car Congress

The challenge of meeting Net-Zero Emissions by 2050 “will be short-circuited and remain out of reach” unless significant new copper supply comes online in a timely way, according to a new study by S&P Global that examines the growing mismatch between available copper supply and future demand resulting from the energy transition.

IEA: governments must act to ensure sufficient supply of critical minerals to meet net-zero goals

Green Car Congress

Part of the IEA’s flagship World Energy Outlook series, the report underscores that the mineral requirements of an energy system powered by clean energy technologies differ profoundly from one that runs on fossil fuels. Wind takes the lead, bolstered by material-intensive offshore wind. Source: IEA.

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. The aircraft has no moving parts, does not depend on fossil fuels to fly, and is completely silent. Most have been powered by fossil-fuel combustion. —Steven Barrett. EAD airplane design.

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.
