Hyundai Motor reveals next generation fuel cell concept at Geneva Motor Show; new SUV Fuel Cell model set for launch in 2018
http://www.greencarcongress.com/2017/03/20170307-hyundaife.html

. . . The FE Concept showcases Hyundai Motor’s fourth-generation of hydrogen fuel cell technology . . . When compared with the current generation system used in the Tucson ix35 Fuel Cell, the new technology is 20% lighter, and achieves 10% greater efficiency. In addition, the power density of the fuel cell stack is increased by 30%, boosting the car’s range significantly. . . .

The car is designed to run for more than 800 kilometers (497 miles) between refueling, acknowledging the current limited hydrogen infrastructure. Elements of the FE Fuel Cell Concept will influence an SUV Fuel Cell model set for launch in 2018, which will feature advanced Hyundai Smart Sense driver assistance technologies, alongside an extensive hydrogen-powered range. . . .

Assuming that 800 km (497 miles) is on either the NEDC or the Japanese test, multiplying by 0.7 translates to about 348 miles EPA, 83 miles/31% better than the Tucson.

Air Products lowers Hydrogen to $9.99 per kg at 5 stations in CA. Cites increased usage volume and improved in station tech as reasons for the drop. No indication if pricing will roll out to other Air Products stations.

Already mentioned in the Ca. H2 stations topic. IIRR, there was already one station charging $9.59 or maybe it was $9.49/kg before this, but this was the first announcement of sub-$10/kg H2 by a chain.

Via GCC, lab results but moving towards commercialization:
Cambridge team demonstrates light-driven photoreforming of unprocessed biomass to H2 at room temperature
http://www.greencarcongress.com/2017/03 ... ridge.html

A team of scientists at the University of Cambridge has reported the light-driven photoreforming of cellulose, hemicellulose and lignin to H2 using semiconducting cadmium sulfide quantum dots in alkaline aqueous solution.

The system operates under visible light, is stable beyond six days and is even able to reform unprocessed lignocellulose, such as wood and paper, under solar irradiation at room temperature, presenting an inexpensive route to drive aqueous proton reduction to H2 through waste biomass oxidation. . . .

The team achieved high rates of H2 evolution, without the photocorrosion of CdS or noble-metal co-catalysts, through use of highly basic conditions that synergistically enabled formation of robust CdS/CdOx and dissolution of lignocellulose.

The oxidation reaction generates CO2 that is sequestered as carbonate, resulting in an overall negative CO2 balance in the atmosphere when taking into account the CO2 fixation required for biomass growth.

Noting that the system’s tolerance to a range of substrates is “particularly appealing” for H2 generation without need for lignocellulose processing, the researchers are now focusing on replacing the Cd with a more environmentally benign metal. . . .

With the help of Cambridge Enterprise, the commercialization arm of the University, a UK patent has been granted and talks are under way with a potential commercial partner.

Successful first test run of Alstom Coradia iLint fuel cell train; signed letters of intent for 60 trainshttp://www.greencarcongress.com/2 ... lstom.html


Alstom successfully performed the first test run at 80 km/h (50 mph) of the fuel cell passenger train Coradia iLint (earlier post) on its own test track in Salzgitter, Lower Saxony (Germany). An extensive test campaign will be conducted in Germany and Czech Republic in the coming months before the Coradia iLint performs its first passenger test runs on the Buxtehude–Bremervörde–Bremerhaven–Cuxhaven (Germany) route beginning of 2018. . . .

The hydrogen used for the test runs is the by-product of an industrial process, which is reasonably reused as a waste product. In the long term, Alstom aims to support the hydrogen production from wind energy. . . .
