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.

Stanford team sets record for solar-to-hydrogen efficiency of solar water splitting: >30%

Green Car Congress

Researchers at Stanford University have demonstrated solar water splitting by photovoltaic-electrolysis with a solar-to-hydrogen (STH) efficiency of more than 30%—a new record. However, the thermodynamic minimum voltage required to electrolyse water is only 1.23 V The prior record was 24.4%. V under 1–1,000 suns of illumination.

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.

Energy Harvesting for Wearable Technology Steps Up

Cars That Think

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.
