and has raised $1 million to commercialize a lithium-ion battery recycling method called Membrane Solvent Extraction, which was developed by scientists at Oak Ridge National Lab. The process dissolves batteries in hydrochloric acid then runs them through membranes wetted with extractant to selectively recover lithium, cobalt, nickel, manganese and other materials.
is developing a new ways to fracture reservoir rock — using pulsed electric stimulation instead. The idea is to insert electrodes down inside a well drilled into a reservoir, then heating up the rock with electric pulses that according to founder, induces thermal stresses and micro fractures through which oil can flow. The tech could save millions of gallons of water per well according to Smalls, who also sees applications in geothermal power development. .
No rep from Energy Web on the list is gonna be embarrassing this year.
