The hydrogen is used in a gas turbine for electricity generation. The reference is an electricity provision from a natural gas-fired power plant. Even the best methane decomposition configuration requires a carbon revenue of 600 to 700€/t to reach cost parity [9]. A different study examines ...
(BEVs), hydrogen fuel-cell electric vehicles (FCEVs), hydrogen internal combustion engines (H2-ICEs), and biofuel or synfuel internal combustion engines (if a sustainable source of carbon is used). Hybrid and gas engines represent bridging technologies to reduce emissions in...
9,10,11, a general and robust strategy is still highly desired for achieving an effective hydrogen spillover on nonreducible oxides with a low density of acid sites or defects, which are widely used as catalyst supports in industry because of their excellent thermochemical stability, low cost, ...

Hydrogen is recognised as an important future energy vector for applications in many sectors. Hydrogen is an indirect climate gas which induces perturbations of methane, ozone, and stratospheric water vapour, three potent greenhouse gases. Using data fro
A challenge is that while stars such as the sun consist mostly of hydrogen, on Earth hydrogen only naturally occurs in compound form with other elements – think water or hydrocarbons such as natural gas and petroleum. The high cost and technology required to...
Advantages of liquid fuel vs. hydrogen for backup power fuel cell systems in telecom The commercially available fuel cell with an integrated liquid fuel processor is an increasingly popular, highly reliable, and cost-effective backup power ... R Romer - IEEE 被引量: 1发表: 2010年 ...
The H2O2 electrogeneration performance and stability of a composite gas diffusion electrode with NO/PC-500 as an electrocatalyst were significantly improved at high current density by introducing a polytetrafluoroethylene (PTFE) hydrophobic layer. A NO/PC-500 (g) to PTFE binder (mL) ratio of 1:...
The CO tolerance measurement were conducted using chronoamperometry at 0.09 V in the presence of 100 ppm CO. For the CO-stripping test, CO gas was firstly bubbled into the electrolyte and the working electrode was held at 0.1 V for 10 min. Then the electrolyte was flushed with...
Among various sensors, gas sensors made by metal oxide semiconductors have gained significant attention from researchers because of their low cost, small size, good stability, and easy production6,7,8. While, due to the complexity of the gas sensing process, the sensing mechanism of them is ...
