Depletion of fresh water reserves [m 3 ]. In addition, it can differentiate between a large number of fuels: Besides the common ones, we have also integrated bio- and synthetic fuels of various origins, and we have considered future technologies such as CO 2 capture and storage in hydrogen production.

They recycled the catalyst over five runs without significant loss of activity (turnover number > 2000). The researchers bubbled air through an aqueous solution of pentaethylenehexamine (or PEHA), adding a catalyst to encourage hydrogen to latch onto the CO 2 under pressure.

Hydrogen for reverse water gas shift reaction to avoid producing CO 2 during the process is produced by electrolyzing water, driven by solar power. For comparison, they also modeled the production of methanol using only biomass as a fuel and also using coal as source of both carbon and energy. Hertwich and Zhang (2009).

Chemists at Brown University have synthesized novel core and shell palladium/iron-platinum (Pd/FePt) nanoparticles that use far less platinum yet perform more efficiently and last longer than commercially available pure-platinum catalysts for the oxygen reduction reaction (ORR) in hydrogen fuel cells.

For the mobility of the future, we are deliberately not committing ourselves to one solitary form of drive system, but to a coexistence of efficient and clean petrol engines, diesels, plug-in hybrids, battery and hydrogen drive systems. In comparison with the previous V6, the CO 2 emissions from the engine have been reduced by around 15%.

Key measurements will include transient temperatures and pressures in the combustion, inlet/exhaust, regenerator and catalyst; inlet and outlet flows; comparisons with baseline operation (without preheating or reforming); and the partitioning of preserved exergy between work potential and hot exhaust.

The hydrogen fuel cell electric vehicle re-fuels in 3–5 minutes, travels up to 300 miles (482 km) on a full tank, and will be available to customers in California beginning in fall 2015. Additional markets will follow, tracking the expansion of a convenient hydrogen refueling infrastructure. High-pressure Hydrogen Tanks.
