Project shows maritime fuel cell generator can increase energy efficiency by up to 30% at part load; reliability and cost issues

Green Car Congress

Project partner Young Brothers operated the generator for 10 months powering refrigerated containers in Honolulu, Hawaii. One opportunity to do so was identified in Honolulu Harbor at the Young Brothers Ltd. (YB) It averaged 29.4 kW (gross). Its net energy efficiency ranged from 36% to 54% over the load range of 16% to 62%.

Fraunhofer researchers report significant extension to Li-S cycle life with silicon anodes and CNT-sulfur composite cathodes

Green Car Congress

Lithium-sulfur batteries are of great interest for electromobility applications, among others, due to their high specific energy and relatively low cost, but are challenged by significant capacity decay over cycling. The interplay between anode and cathode is the critical factor determining the performance and lifespan of a battery.

Alcoa and Phinergy enter joint development agreement for high energy-density aluminum-air batteries

Green Car Congress

Alcoa and Israel-based Phinergy have entered into a joint development agreement to develop further Phinergy ’s aluminum-air batteries. Aluminium–air cells are high-energy density primary (non-rechargeable) batteries originally developed in the 1960s. kWh/kg of Al—second only to the Li-air battery (13.0 Earlier post.).
