Solar Powered Hydrogen Fuel – The Rebellion

Benji Jerew — Wed, 18 Jun 2014 16:07:25 +0000

Hydrogen fuel cell and battery electric vehicles have one very important thing in common: they’re both emissions-free sort of. While it’s true that hydrogen fuel cell and battery electric vehicles do not generate any emissions in themselves, their upstream emissions cannot be ignored. Really, it all depends on where the power grid gets its electricity […]

Hydrogen Fuel Generation – Breakthrough Catalyst Investigated in India

Benji Jerew — Fri, 19 Apr 2013 15:50:03 +0000

Hydrogen fuel used in hydrogen fuel cells, as a replacement for natural gas, or even in an internal combustion engine, burns clean and emits zero carbon dioxide. This is great news for those concerned about increasing carbon dioxide emissions, but the current-best method for generating hydrogen fuel isn’t very efficient. Electrolysis uses electricity to split […]

New Hydrogen Generator is More Efficient and Less Expensive

Benji Jerew — Fri, 29 Mar 2013 21:56:20 +0000

The basics of a fully functional hydrogen economy have to include both efficient and inexpensive hydrogen generators and fuel cells. Electrolytic cells generate hydrogen and oxygen gas from water using an electric current. They are not particularly efficient however, as the energy in the resulting hydrogen and oxygen is less than that which was used […]

New Catalyst for Electrolysis Reduces Costs by 97% and Increases Hydrogen Production Fourfold

Ovidiu Sandru — Wed, 19 May 2010 18:30:18 +0000

Hydrogen, the cleanest energy storage in the Universe, is most of the time associated with high costs, although it is extracted from water, which is the cheapest yet the most precious element to life. Extracting hydrogen from water is done through a method called electrolysis, but doing electrolysis efficiently requires the usage of catalysts such as platinum, which is very expensive.

Video: Jack Nicholson Drives Hydrogen Car in 1978!

Ovidiu Sandru — Thu, 24 Jul 2008 19:49:08 +0000

This video is a clip from a 1978 CBC News, showing Jack Nicholson driving a hydrogen powered car. The concept existed since then, the hydrogen was packed in high pressure tanks, and the engine's timing (top dead center) was retarded a bit (probably 8 degrees, it's a common value). And, as extra value, the hydrogen was obtained from solar power, through some solar panels, cutting edge tech at that time.

Cheapest Way to Get Hydrogen: the Photoelectrochemical Diode

Ovidiu Sandru — Tue, 22 Jul 2008 19:59:28 +0000

Penn State researchers have found a cheaper method of producing hydrogen from water by the same old effect of electrolysis aided by the Sun's rays. They do not use classic solar cells, because these are expensive, but made a nanotechnology-based solar cell, called photoelectrochemical diode, that is simplistically said on the bottom of the water holding recipe.
