Add electric vehicles, not bulk transmission, for a low-cost, clean grid: UC Berkeley study

A 90% clean grid with a transition to EVs would achieve lower electricity costs than one without, the study shows. Transmission investments would mainly be spur lines to new renewable generation.

British company to produce solid-state lithium-sulfur products this year

Oxfordshire-based Oxis Energy says it will produce the less flammable devices sought by the aviation industry using the same manufacturing processes as those used to make lithium-ion and conventional-lithium-sulfur products.

GM and LG Energy plan a $2.3 billion electric vehicle battery plant

The automaker’s future Ultium-powered EVs are designed for Level 2 and DC fast charging. Most will have 400V battery packs and up to 200 kW fast charging capability.

Italy should embrace solar, not gas to hit raised climate ambition

Instead of splurging €11 billion of EU cash on uneconomic new generation capacity, the Italian authorities–and electricity bill payers–would be better served investing in a mix of current clean power technologies which would include almost 17 GW more solar capacity.

Using PET waste bottles to make batteries

Scientists in the U.S. claim to have successfully upcycled PET waste bottles into an electrochemical active-carbon material that functions as a double‐layer supercapacitor substance. They said that this achievement may lay the ground for the production of more sustainable batteries. Devices built with the proposed technique would not store as much energy as lithium-ion batteries but they could charge much faster.
