Caltech’s ‘Artificial Leaf’ Could Revolutionize the Hydrogen Economy

Satya Sivani — Mon, 14 Sep 2015 19:42:20 +0000

Caltech institutions’s newly invented ‘Artificial leaf‘ is a highly efficient stand-alone photoelectrochemical (PEC) device which can split water into hydrogen and oxygen using sun light. “The first car driven by a child born today could be powered by hydrogen and pollution free,” ex-President George W. Bush said in his 2003 State of the Union address to the scientists […]

We know that renewable energy, such as hydrogen fuel cell technology, could be the future of energy and transportation, but if it isn’t economically viable, then why bother? The answer, of course, is because it is the right thing to do. Researchers have spent decades researching ways to clean up our act with regards to […]

Hydrogen [H2] as a power source has been under on-and-off development and use in various sectors since the 1900s, but has its own special considerations when it comes to storage and use. The high reactivity of H2 makes it an excellent fuel, but also difficult to store and deliver. Combustion of H2 also produces no […]

Usually, to get hydrogen, the first method that you think of is the electrolysis of water. However, this is not the most efficient way to get the precious energy-carrying gas, and as hydrogen cars will slowly emerge on the market it will need production efficiency, not only the mere fact that it works. So far, […]

Argonne Researchers Splitting Water 10 Times Faster With New Metallic Compound

Mike Sandru — Tue, 03 Jan 2012 19:05:01 +0000

Due to its storage capacity, hydrogen has an enormous potential in the clean energy industry. Unfortunately, it is very hard to “master”: only setting apart single atoms costs a fortune! Luckily for us, researchers at the Argonne National Laboratory succeeded in splitting hydrogen molecules ten times faster, which is a lot cleaner and less expensive […]

Iron "Veins" Inside Magnesium Could Make the Perfect Solution for Hydrogen Storage

Ovidiu Sandru — Wed, 31 Aug 2011 20:04:41 +0000

A principle that mother nature uses since millions of years ago may just be the solution to an efficient hydrogen storage material, as hydrogen is the ultimate energy carrier, because burning it emits nothing but water. So far, the few hydrogen-powered cars that are not even on the market yet, but merely as leased test […]

Linde`s Ionic Hydrogen Compressor Offering Better Fueling Stations

Ovidiu Sandru — Tue, 31 Mar 2009 12:10:11 +0000

In this new era of alternative fuels, oil companies can't just stand there and watch electricity and hydrogen take the place of their classic beloved petrol consuming machines. The best strategy they found is the most common-sensed one: get involved little by little in the business, adapt to the market's needs, and perhaps change your image to the public from black oil to green leaves.

New Palladium Nanoparticles Making Fuel Cells Better

Ovidiu Sandru — Mon, 23 Mar 2009 12:30:10 +0000

Nowadays, the cost of a hydrogen fuel cell is mostly increased by the cost of its components, and mostly by platinum. In the search for finding better materials for making fuel cells, researchers have already found alternatives to the expensive platinum a long time ago, but they were not as efficient. One of this substitute materials is palladium - far cheaper and much more abundant, but that didn't have enough surface area to make the fuel cell catalysis efficient.
