Scientists Achieve Solar Hydrogen Production Breakthrough

Scientists Achieve Solar Hydrogen Production Breakthrough | Cool Future Technologies | Scoop.it

A newly published study reveals how scientists used a solar cell and a photo anode made of a metal oxide to achieve a solar hydrogen production breakthrough.

 

The experts were able to develop a rather elegant and simple system for using sunlight to split water into hydrogen and oxygen.

 

This process, called artificial photosynthesis, allows solar energy to be stored in the form of hydrogen. The hydrogen can then be used as a fuel either directly or in the form of methane, or it can generate electricity in a fuel cell.

 

One rough estimate shows the potential inherent in this technology: At a solar performance in Germany of roughly 600 Watts per square meter, 100 square meters of this type of system is theoretically capable of storing 3 kilowatt hours of energy in the form of hydrogen in just one single hour of sunshine. This energy could then be available at night or on cloudy days.

 
Sepp Hasslberger's insight:

Looks like a neat advance in solar technology. Storage of electrical energy is always a problem and producing hydrogen builds the storage right in, with a fuel that can be used in a variety of ways ...

Glass in capacitors: New capabilities for energy storage found in Pennsylvania University

Glass in capacitors: New capabilities for energy storage found in Pennsylvania University | Cool Future Technologies | Scoop.it

In a recent paper in the new journal Energy Technology, postdoctoral researcher and lead author Mohan Manoharan and colleagues report on experiments with various alkali-free glass compositions and thicknesses, comparing their energy density and power density to commercial polymer capacitors currently used in electric vehicles to convert energy from the battery to the electric motor.

 

Because polymer capacitors are designed to operate at lower temperatures, they require a separate cooling system and a larger safety factor, which adds to their bulk.

 

In his research, Manoharan identified 10-micron thick glass from Nippon Electric Glass (NEG) as having an ideal combination of high energy density and power density, with high charge-discharge efficiency at temperatures up to 180 °C and, in more recent experiments, even higher.

Sepp Hasslberger's insight:

Graphene and the New Age of Carbon

Graphene and the New Age of Carbon | Cool Future Technologies | Scoop.it

The new superstar in materials science and condensed matter physics is a flat single layer of carbon atoms packed into a crystalline honeycomb lattice that could go on forever.

 

Curled up, it gives fullerenes (the familiar buckyballs), rolled up, it forms carbon nanotubes, and stacked up in layers, it is the graphite in our pencils.

 

Electronically, graphene is a superconductor even at room temperatures. It conducts much easier and faster than copper and at a million times the current density...

Sepp Hasslberger's insight:

Graphene is relatively simple to make, and the raw material for it is abundant. There are many applications for it in computers, solar energy catchers, and other things.

High pressure water/steam system releases hydrogen bonds, produces excess energy

High pressure water/steam system releases hydrogen bonds, produces excess energy | Cool Future Technologies | Scoop.it

Richard Aho of MIST Energy Systems has been working for years on the idea that hydrogen bond energy could be harnessed. He went on working where others had abandoned the field because they knew it "couldn't be done".


In his Mist Energy System, water is pressurized by a commercially available high pressure pump, it is then released through a nozzle into an impact chamber, where the jet hits a metal target. Heat is released and the water instantly transforms into steam.

 

The energy spent to pressurize the water and pre-heat the impact chamber is about one tenth of the energy contained in the steam that is produced. 

Sepp Hasslberger's insight:

Enough about this "clean energy just can't be done, we need (coal, oil, gas, atomic power) to meet energy needs". There ARE clean technologies that can produce energy. This is one of them. No more excuses...

Turn water into fuel - Edward Mitchell to bring Stanley Meyer's Water Fuel Capacitor to life

Turn water into fuel - Edward Mitchell to bring Stanley Meyer's Water Fuel Capacitor to life | Cool Future Technologies | Scoop.it

The Water Capacitor turns water into a hydrogen-oxygen gas mixture that can then be used as a fuel for heating, cooking, welding, fixed generators, and powering internal combustion engines.


The Water Capacitor will then be incorporated into a kit offered from True Green solutions to individual consumers.

 

The Proof of Principle was demonstrated in Stanley Meyer's original water splitting devices as hydrogen fuel was extracted from water with his Electrical Polarization invention that was documented in his patents through the mode of operability. 

 

Edward Mitchell has already built a working prototype and is now refining the design to be incorporated into a complete Exciter Array (Water Fuel Capacitor(C)) Kit. 

Sepp Hasslberger's insight:

Stanley Meyer died an untimely death just after he had secured a $ 5m investment to start commercial production of his super efficient water splitting technology.

Edward Mitchell continued in Meyer's footsteps and is ready to develop a kit. He does need funds to do that. This is his crowdfunding campaign.

A nanotechnology use for hemp

A nanotechnology use for hemp | Cool Future Technologies | Scoop.it
Researchers have come up with various electrode materials to improve the performance of supercapacitors, focussing mostly on porous carbon due to its high surface areas, tunable structures, good conductivities, and low cost.

 

"We were able to achieve this by employing a biomass precursor with a unique structure – hemp bast fiber," Zhi Li, a post doc researcher in David Mitlin's group at the University of Alberta, tells Nanowerk. "The resultant graphene-like nanosheets possess fundamentally different properties (pore size distribution, physical interconnectedness and electrical conductivity) as compared to conventional biomass-derived activated carbons."

Sepp Hasslberger's insight:

As we learn more, our political aberrations - yes, prohibition is a purely political aberration with a moralistic background - become obvious.

Breakthrough in hydrogen fuel production could revolutionize alternative energy market

Breakthrough in hydrogen fuel production could revolutionize alternative energy market | Cool Future Technologies | Scoop.it
A team of Virginia Tech researchers has discovered a way to extract large quantities of hydrogen from any plant, a breakthrough that has the potential to bring a low-cost, environmentally friendly fuel source to the world.

 

To liberate the hydrogen, Virginia Tech scientists separated a number of enzymes from their native microorganisms to create a customized enzyme cocktail that does not occur in nature. The enzymes, when combined with xylose and a polyphosphate, liberate the unprecedentedly high volume of hydrogen from xylose, resulting in the production of about three times as much hydrogen as other hydrogen-producing microorganisms.

 

The energy stored in xylose splits water molecules, yielding high-purity hydrogen that can be directly utilized by proton-exchange membrane fuel cells. Even more appealing, this reaction occurs at low temperatures, generating hydrogen energy that is greater than the chemical energy stored in xylose and the polyphosphate. This results in an energy efficiency of more than 100 percent — a net energy gain. That means that low-temperature waste heat can be used to produce high-quality chemical energy hydrogen for the first time. 

 

Sepp Hasslberger's insight:

This could be a game-changer, something to jump start the hydrogen economy which has the potential to make fossil fuels a thing of the past...

You might think that as one of the world's top oil producing nations, the United Arab Emirates would have little use for solar energy. But that hasn't stopped the Middle East state from unveiling the largest concentrated solar power plant in operation anywhere in the world. 

The 100-megawatt solar-thermal project in Abu Dhabi will power thousands of homes in the country and, it is hoped, displace approximately 175,000 tons of CO2 per year.

Sepp Hasslberger's insight:

It took $ 600 million and 3 years to build this - not bad for a plant that doesn't need fuel, leaves no polluting exhaust and is extremely safe. Arabia could be exporting electricity instead of oil. Future business for desert countries?

Making Salt Water Drinkable Just Got 99 Percent Easier

Making Salt Water Drinkable Just Got 99 Percent Easier | Cool Future Technologies | Scoop.it
Access to steady supplies of clean water is getting more and more difficult in the developing world, especially as demand skyrockets.

 

Lockheed Martin's Perforene, on the other hand, is made from single atom-thick sheets of graphene. Because the sheets are so thin, water flows through them far more easily than through a conventional TFC.

 

Filters made through the Perforene process would incorporate filtering holes just 100 nm in diameter—large enough to let water molecules through but small enough to capture dissolved salts. It looks a bit like chicken wire when viewed under a microscope

Sepp Hasslberger's insight:

This looks like a quantum leap on desalinization of sea water - making availability of drinking water from the sea a very real possibility, without huge and power hungry reverse osmosis desalinization plants.

Only 3% of the water in the planet is freshwater meaning non salty water. With this technology we will fully take advantage of the Earth's water. We could even rename our planet and call it "Water"
timallard's comment, June 24, 2013 3:08 PM
My work is a miniaturized system for home-farm-ranch that copies larger sewage treatment plants yet uses algae to clean the water not floccing chemicals. Bioreactors are used for this and most made for large batch processing so my design is a cube 1/2m on a side full of glass plates that light the entire volume well, easy to aerate and will include harvesting to a slurry that's processed for biodiesel, a high-volume supply. Then the de-watered cakes are quality fertilizer so you get pure water, biodiesel and fertilizer from this system intended to be sold in home-farm supply stores with parts and service people.

With this a small dairy operation can produce their fuel from the washdown, getting the water back as well and fertilzer so it's clear the benefits possible from bringing this to the market.

Have we found the 'holy grail' in cutting emissions? Power plant claims to produce hydrogen by splitting water with sunlight

Have we found the 'holy grail' in cutting emissions? Power plant claims to produce hydrogen by splitting water with sunlight | Cool Future Technologies | Scoop.it

The University of Colorado at Boulder has designed a hydrogen plant that uses an array of mirrors to focus sunlight onto a huge tower. The tower heats up to 1,350 °C - enough to liberate hydrogen from steam.

 

‘We have designed something here that is very different from other methods and frankly something that nobody thought was possible before,’ said lead scientist Professor Alan Weimer, from the University of Colorado at Boulder.


‘Splitting water with sunlight is the Holy Grail of a sustainable hydrogen economy.’


Hydrogen could be used as a fuel for road transport, distributed heat and power generation, and for energy storage.

Sepp Hasslberger's insight:

Slowly getting there ... when the universities get in on the act, we just might end up with a clean energy economy!

Two chemists at the University of California Los Angeles, Maher Elkady and Richard Kaner, have produced an impressive prototype array of graphene micro-supercapacitors using little more than a home-version DVD laser burner.

 

They also found that miniaturizing the device to micron scale results in enhanced charge-storage capacity and performance, giving a power density of ~200 W cm-3, among the highest achieved for any supercapacitor.

 

The process is readily scalable and the devices can be made on large substrates at a fraction of the cost of traditional microfabrication methods.

Compressed air is an ideal way to store energy from those modern day windmills. 

 

The method tends to equal out periods of much wind with those lacking it, and is able to deliver a constant flow of electricity to the net.

'Artificial leaf' gains the ability to self-heal damage and produce energy from dirty water

'Artificial leaf' gains the ability to self-heal damage and produce energy from dirty water | Cool Future Technologies | Scoop.it

Nocera, leader of the research team, explained that the “leaf” mimics the ability of real leaves to produce energy from sunlight and water. The device, however, actually is a simple catalyst-coated wafer of silicon, rather than a complicated reproduction of the photosynthesis mechanism in real leaves.

 

Dropped into a jar of water and exposed to sunlight, catalysts in the device break water down into its components, hydrogen and oxygen. Those gases bubble up and can be collected and used as fuel to produce electricity in fuel cells.

 

“Surprisingly, some of the catalysts we’ve developed for use in the artificial leaf device actually heal themselves,” Nocera said. “They are a kind of ‘living catalyst.’ This is an important innovation that eases one of the concerns about initial use of the leaf in developing countries and other remote areas.”

3. 3D Printing

 

Even in relative the infancy of 3D printing, there are those seeking to extend this technology to deliver greater benefits. This article discusses the extensions of 3D printing in to areas not first imagined such as the printing of food. It then extends from 3D printing to assembling also. Virtually producing fully functioning cars from atoms and making them ready to drive 'hot' off the printer. This provides endless opportunities for all to be shopping and purchasing without doing either - just printing and using. No shipping costs - no middle man.

Brendan Chan's curator insight, March 26, 2015 5:36 AM

The implication of 3d printing are enormous. Scientists expect 3d printing to cut forms of delving  and decrease poullution as long as the printer has the right materials to create the desired item. Items can be recycled from another  for a considerable time. Items will be fully assembled and fully functional from the start. The concept of 3d printers challenges capitalism, employment or companies, as products can be everywhere as long as there is a printer.
