A fight over a vital federal tax credit intended to kickstart a market for low and no carbon hydrogen and worries over high production costs are cooling near-term expectations for the green hydrogen fuel. 为启动低碳和无碳氢市场而展开的一项重要联邦税收抵免之争,以及对高昂生产成本的担忧,正在降低...
Forklift propulsion systems and distributed power generation are identified as potential fuel cell applications for near-term markets. This analysis examin... A Elgowainy,L Gaines,M Wang - 《International Journal of Hydrogen Energy》 被引量: 44发表: 2009年 Full-Fuel-Cycle Approach to Vehicle Emis...
GM was one of the first automakers to stick a hydrogen fuel cell into a vehicle It’s still “early days,” Hydrotec’s executive director, Charlie Freese, tells me. GM is still testing its technology to see what works and what won’t. In addition to the trucks, there’s also the ...
Road locomotives and switchers will require different energy-management systems because of the different demands of each type of service. Fuel cells prefer producing a consistent amount of power, Moslener says, so switchers would need to draw electricity from batteries rather than tap the fuel cell...

Hydrogen and fuel production are evaluated regarding cost and GHG emissions throughout the lifetime of the production plants. The following utilizes the current dominating production pathways for comparison purposes. A framework for a comprehensive comparison is set-up considering a near-term and large...
Hydrogen is deliberated to be the promising and appealing fuel in the future world. Compared with the widely employed steam reformed hydrogen (such as the reaction of methane and water to form H2 and CO2), electrocatalytically produced H2 from water splitting can be more renewable, scalable and ...
H2 fuel, for fuel cells, is traditionally produced from methanol by the endothermic steam reforming of methanol (SRM). Partial oxidation of methanol (POM), which is highly exothermic, has also been suggested as a route to extract H2 from methanol. In both these reactions a considerable amount...
The O escape energy on Mars is near 2.0 eV, varying slightly with the altitude because the gravitational acceleration is inversely proportional to the square of the distance. 回到H原子逃逸问题, 我们注意到: 使用金斯公式计算逃逸通量意味着电离层化学(见第3节)释放的H原子可以与背景大气发生充分碰撞...
Hydrogen is gaining traction as a promising alternative fuel in aviation due to its high energy density per unit mass and eco-friendly characteristics. This study delves into the realm of physical and material-based hydrogen storage tailored for aeronautical purposes. Key hurdles include achieving subs...
