100% renewable targets will require power storage to manage flows on the net
Electrolysers utilise these intermittent power flows to produce H2 gas from water
H2 gas can be stored in large quantities underground and transported via existing gas pipelines
H2 vehicles recharge faster and are more durable than battery powered transport
Growing H2 demand in industrial processes will reduce costs and increase supply

ZEM Evolution is a new Italian bus manufacturer, developing at this moment a range of electric and hybrid buses, including a hydrogen fuel cell version. The company formed last year in Brescia and headed by engineer mechanical Pierpaolo Fusari, founder of EPT (Eco Power Technology), a manufacturer of hybrid buses. Recently, ZEM Evolution unveiled designs for two buses (from 8 to 10 meters in length) and two chassis for garbage trucks. “Plans are to start production in 2011,” announced Fusari, who adds that the ZEM Evolution vehicles will have no equal in Europe with regard to materials used. for new vehicles, “we would like to emphasize. “A lightweight aluminium frame forms the basis of an integrally constructed body.” With regard to the driveline technology ZEM is in partnership with a number of suppliers to fit the lightweight all-aluminium bus with various hybrid driveline options. Another interesting implementation is the use of super capacitors on the ZEM product range ensuring that all hybrid versions, which will either be powered by a microturbine or fuel cells, used to charge the super capacitors and batteries with energy. Also fitted is a brake energy recuperation system enabling the buses to drive up to 300 km between charges. Source: Bus World
