Benefits of hydrogen

Local air emissions, responsible for particulate matter, ozone and acid rain, as well as noise, could be significantly reduced by the introduction of hydrogen fuel-cell vehicles. Emissions of NOx, S02 and particulates can be reduced by 70% to 80% compared to a case without hydrogen. Especially in densely populated areas this is one major benefit of hydrogen, which is often underestimated. As there are a growing... 

What would be the geometry of the guanine-cytosine complex were there no hydrogen bonds or, more to the point, were chemists not to know about the benefits of hydrogen bonding More than likely, it would be a more closely-packed geometry, such as the following. 

Barriers and Benefits of Hydrogen-based Autonomous Power Systems. 151... 

Moreover, hands-on experience of potential users in the operation of demonstration projects will facilitate removal of these market-related barriers. The environmental benefits of hydrogen will also play a significant role for potential... 

The forum discussion was framed in the context of whether private-sector companies or the government should make investments in hydrogen research, development, and deployment. While forum participants did not address the costs of hydrogen, they identified the following potential benefits of hydrogen, which warrant further examination and assessment ... 

Perceived Benefits of Hydrogen Cited by Forum Participants... 

Another possible scenario for wind farms is to use the electrical power generated to decompose water to produce hydrogen gas that could be carried to cities by pipelines and used as a fuel. One real benefit of hydrogen is that it produces water as its only combustion product. Thus, it is essentially pollution-free. 

Third, the incremental benefits of hydrogen and fuel cell vehicles to consumers are likely to be very small relative to conventional technology vehicles and fuels. Policies to value the social benefits of hydrogen and fuel cell vehicles will be needed, or at least considered, to stimulate consumer demand enough to achieve the timetable and scale of transition envisioned.
