Electra raises $85M to advance Low-Temperature Iron process; electrochemical refining at 60?C

Green Car Congress

The “Iron Ore Challenge”: Commercial iron ores with iron content of 62% or higher are projected to be in short supply by the early 2030s. Hydrogen or natural gas-based steelmaking requires ores with the highest iron content at 67% or above, making the cost and ore supply challenge even more acute for these processes.

C40 Cities: urban consumption-based emissions must be cut by 50% by 2030, 66% for high-income areas; buildings, food, transport, clothing, electronics, appliances, aviation

Green Car Congress

Food: Mayors, business, and citizens in C40 cities could together take actions to reduce consumption-based emissions from food by an average of 31-37% by 2030, depending on the target level, by moving to a plant-based diet, eating healthy quantities and avoiding waste.

Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

Any person who controls an electrical grid is very cautious about what you sync to their grid, because you could disrupt the grid. The compressor gets the supercritical CO 2 up to the necessary pressure before it meets up with waste heat in the recuperator and returns to the heater to continue the cycle.

DOE researchers develop energy-efficient, cost-effective process to extract rare earth elements from scrapped magnets

Green Car Congress

It’s an improvement over traditional processes, which require facilities with a large footprint, high capital and operating costs and a large amount of waste generated. Extracting desirable elements without co-extracting undesirable ones means less waste is created that will need downstream treatment and disposal. —Ramesh Bhave.
