U Alberta team develops hybrid sodium-ion capacitor; intermediate in energy & power between ultracaps and batteries

Green Car Congress

A team led by researchers from the University of Alberta (Canada) Scientists has developed a hybrid sodium-ion capacitor (NIC) using active materials in both the anode and the cathode derived entirely from peanut shells—a green and highly economical waste globally generated at more than 6 million tons per year. Batteries'

Novozymes launches commercial enzyme technology to convert waste oils into biodiesel

Green Car Congress

waste oils with high FFAs have not been a viable feedstock option. The enzymatic process eliminates the need for sodium methoxide, one of the most hazardous chemicals in traditional biodiesel plants. The significant reduction of harsh chemicals and by-products enhances safety for both personnel and the environment.

Aqua Metals is building a more sustainable battery recycling ecosystem

Charged EVs

Several companies are developing chemical processes, but these are still at pilot scale, and Aqua’s execs see serious challenges in delivering the required product purity and dealing with waste streams. The more collection we do, the better for the environment. Charged : How could we make sure more of that gets collected?

Lund researchers develop optimized two-phase enzymatic process for production of biodiesel

Green Car Congress

The current predominant method for the transesterification of triglycerides (plant and animal oils and fats) to biodiesel (a mixture of esters) uses chemical catalysts (sodium or potassium hydroxides or alkoxides). For that reason, two-phase reaction media seem to be the most suitable environment for these particular enzymes.

Energy Harvesting for Wearable Technology Steps Up

Cars That Think

Solar won’t work for nocturnal animals or creatures in low-light environments. The group fabricated their device using CFRP, sodium potassium niobate (KNN) nanoparticles, and epoxy resin. If I measure your heartbeat in picoseconds, that would be a waste because your heart doesn’t beat that quickly,” he says.
