Whither hydrogen?

Environmental Economics

city will have a fleet (more than 10) of public vehicles--buses, or taxis, or garbage collection or police or whatever--powered by hydrogen.    As I see it, the major hurdles with hydrogen powered vehicles are: 1) Developing a fuel cell that will be cheap enough to mass produceand sell.  2) Producing hydrogen.    Initially, hydrogen production will be fossil fuel based.  Cue flashback music.

Future Perfect: Producing hydrogen fuel from wastewater

EcoFriend

We have been listening about the green potentials of hydrogen based energy technology for quite some time now. Reason for this is the fact that hydrogen is an energy carrier, which doesn’t occur naturally. And, the artificial production of hydrogen faces huge technological and cost based challenges. It has been shown that hydrogen could be produced from wastewater through new carbon neutral processes. The hydrogen can then be used in fuel cells.

Student creates solar reactor to produce hydrogen

EcoFriend

Sonia Renthlei: Generating hydrogen from renewables is a question which has baffled scientists the world over. Traditionally, hydrogen is created from natural gas. The process facilitates the release of greenhouse gases as it is transformed into hydrogen. Laird and Suresh Advani, have created a reactor that utilizes zinc oxide powder and highly concentrated sunlight to create solar hydrogen, a clean and sustainable fuel with no emissions.

What is hydrogen?

Eco Friendly Daily

Not only is Hydrogen one of the simplest elements known to man (each hydrogen atom has only one proton); it is also the most plentiful gas in the universe, especially if you consider that stars are primarily made-up of hydrogen. Yes, this would infer that sun is hydrogen, inclusive of helium, which through a process of fusion, gives us radiant (and solar) energy. So given the abundance of hydrogen, why haven’t we capitalized more on it as a source of fuel?
