“Artificial Leaf” Produces Energy from Dirty Water, Can Self-Heal

Artificial Leaf

The world’s first practical “artificial leaf”, capable of producing clean energy from dirty water, has gained a new feature – that of being able to heal itself of any damage that occurs during energy production. The artificial leaf mimics the ability of real leaves to produce energy from sunlight and water, but this version breaks water down into hydrogen and oxygen, which can be collected and used as fuel to generate electricity in fuel cells. The leaf is a catalyst-coated wafer of silicon that is said to be able to turn one quart of drinking water into 100 watts of… read more

New Process Produces Hydrogen from Any Biomass

Virginia Tech University researchers have discovered a process for producing large quantities of hydrogen from virtually any plant material, making it a very real possibility that the cheap clean fuel of the future is hydrogen. An associate professor at the university, Y.H. Percival Zhang, along with his team, has successfully used xylose, a plant sugar, to produce hydrogen in large quantities, a method possible using any source of biomass. “Our new process could help end our dependence on fossil fuels. Hydrogen is one of the most important biofuels of the future.” – Zhang While the process was possible in theory… read more

New Discovery Makes Hydrogen Production 1000% Cheaper

Simon Trudel and Curtis Berlinguette

One of the biggest issues in solar and wind power production is that of the variability of the power production throughout the day and throughout the year, and because of that, there is a great need for affordable and effective energy storage systems for both small and large scale use. Batteries keep getting more and more efficient, but buying large battery banks isn’t always the most effective (or cheapest) way to store energy from peak supply to cover peak power demands. However, a new discovery by a pair of scientists at the University of Calgary may make it feasible to… read more

Hybrid vs Hydrogen

Hybrid vs Hydrogen

The problem with hybrid is simple, it still uses gasoline.  However, hydrogen cell vehicles do not use gasoline, they are fueled by hydrogen. So the question is why we are not using this technology at the pump. Actually the answer to that is they are. California is equipped with many stations that help fuel Honda’s FCX Clarity. It is a zero emissions hydrogen powered sedan. The hydrogen tank stores the hydrogen, the V Flow cell stack then generates the electricity in which the lithium-ion battery stores the electricity. Then the PDU (power drive unit) governs the electrical flow and the… read more
