Simple process transforms PET plastic into a nanomaterial for supercapacitors

Green Car Congress

UC Riverside (UCR) engineers have developed a way to recycle PET (polyethylene terephthalate) plastic waste, such as soda or water bottles, into a nanomaterial useful for energy storage. Then, using an electrospinning process, they fabricated microscopic fibers from the polymer and carbonized the plastic threads in a furnace.

Hyundai is going all in on hydrogen, and relying on food waste to make that happen

Baua Electric

But now it says it will rely heavily on hydrogen fuel cells generated from plastic, food, and organic waste to power a whole new generation of EVs, from passenger cars to heavy-duty trucks. For the Nexo, a recharge can take you 380 miles, with its only emissions being water vapor. It has set its target as the far-away date of 2050.

Blue World Technologies takes 15% stake in Danish Power Systems; methanol fuel cell vehicles

Green Car Congress

A closed thermal integration enables reuse of fuel cell waste heat for fuel evaporation thereby increasing efficiency. Methanol reforming converts a mix of methanol and water into a hydrogen-rich gas. Waste heat can be utilized for cabin/battery heating and fuel tank can be placed where chassis design allows it.

STFC Rutherford Appleton Lab spin-off seeking to develop and commercialize a novel solid-state hydrogen storage technology; transportation applications

Green Car Congress

Example of micro fibers produced with 20 wt % AB (ammonia borane) in water as core solution, showing smooth (nonporous) and cylindrical (noncollapsed) fibers; from a 2010 paper by the scientific team. The material could allow hydrogen to be stored in a cheap and practical way for transport applications, the company says.

Using built-in fuel cells, the device absorbed the lactate in the sweat and combined it with atmospheric oxygen to generate water and pyruvate. For capacitors, voltage translates to electrons stored —the voltage drop across a capacitor is proportional to its total charge.) volts for about 60 hours. They said, ‘We don’t know.

Penn State team develops more environmentally friendly method for separating bitumen or oil from sands using ionic liquids

Green Car Congress

The Penn State separation method uses very little energy and water, and all solvents are recycled and reused. The separation takes place at room temperature without the generation of waste process water. Extraction and separation of bitumen from surface-mined oil sands involves the use of significant amounts of energy and water.

The inner layer consists of gas-impermeable polyamide polymer, while a second layer of carbon fiber-reinforced polymer (CFRP) gives the tank its extremely high strength; a third layer of glass fiber reinforced polymer (GFRP) provides rugged protection against damage from the outside.
