Scientists Accidentally Discover Efficient Process to Turn CO2 Into Ethanol. Scientists at the Oak Ridge National Laboratory in Tennessee have discovered a chemical reaction to turn CO2 into ethanol, potentially creating a new technology to help avert climate change.
Their findings were published in the journal ChemistrySelect. The researchers were attempting to find a series of chemical reactions that could turn CO2 into a useful fuel, when they realized the first step in their process managed to do it all by itself. The reaction turns CO2 into ethanol, which could in turn be used to power generators and vehicles.

New 'nano-reactor' biomaterial catalyzes hydrogen biofuel. BLOOMINGTON, Ind., Jan. 5 (UPI) -- By hiding a modified enzyme inside a virus, researchers have created a new biomaterial capable of efficiently catalyzing the production of hydrogen.
The so-called "nano-reactor" could lead to more efficient and profitable biofuel production processes. Inside a capsid, the protective protein shell of a virus, the hydrogen-producing enzyme is 150 times more efficient than an unaltered enzyme. "Essentially, we've taken a virus's ability to self-assemble myriad genetic building blocks and incorporated a very fragile and sensitive enzyme with the remarkable property of taking in protons and spitting out hydrogen gas," researcher Trevor Douglas, a chemist at Indiana University, explained in a press release.
Researchers just made batteries from mushrooms... and they're surprisingly good. Researchers in the US have created a new type of lithium-ion battery that uses portabella mushrooms - yes, you read that right - instead of the graphite that currently forms the batteries inside our mobile phones.
And while it sounds like the type of idea you might hear at a high school science fair, evidence suggests that these new batteries might actually last longer than traditional batteries, and could give our phones better battery life as they age. And that's not all - the mushroom batteries are also incredibly cheap, easy to make, and, best of all, they're pretty much biodegradable.
Which will make a big difference to the environment as our demand for batteries skyrockets with the 6 million electric vehicles predicted to be built by 2020. Scientists make huge hydrogen energy discovery. It’s one of the holy grails of the energy industry: a cost-effective way to generate hydrogen, and a team of researchers thinks they may have just found it.
Scientists at the University of Wisconsin believe the have found a cheap and efficient way to produce hydrogen without having to use noble gases as a catalyst, and they were able to do it by combining phosphorous and sulfur, two common elements, as well as cobalt, a metal that is much cheaper than even the cheapest noble metal, according to a UPI report. It’s an important discovery because scientists hope to fuel the future world with an eco-friendly source, and hydrogen could be that source: it can be burned for heat or used in fuel cells, and they don’t give off bad emissions like fossil fuels when burned: hydrogen’s byproduct is water.
But the technology to make that happen in a cost-effective way has eluded scientists. They have had to use incredibly expensive noble metals like platinum to split the water and generate hydrogen. Angela Belcher: Using nature to grow batteries. Sugar-powered biobattery has 10 times the energy storage of lithium: Your smartphone might soon run on enzymes. As you probably know, from sucking down cans of Coke and masticating on candy, sugar — glucose, fructose, sucrose, dextrose — is an excellent source of energy. Biologically speaking, sugar molecules are energy-dense, easy to transport, and cheap to digest. There is a reason why almost every living cell on Earth generates its energy (ATP) from glucose. Now, researchers at Virginia Tech have successfully created a sugar-powered fuel cell that has an energy storage density of 596 amp-hours per kilo — or “one order of magnitude” higher than lithium-ion batteries.
This fuel cell is refillable with a solution of maltodextrin, and its only by products are electricity and water. The chief researcher, Y.H. Now, it’s not exactly news that sugar is an excellent energy source. A fully transparent solar cell that could make every window and screen a power source.
New "Solar Fuel Cell" Is More Efficient By A Factor Of 10. Clean Power Published on July 22nd, 2015 | by Tina Casey July 22nd, 2015 by Tina Casey Providing a new ray of hope for hydrogen fuel cell fans, researchers at Eindhoven University of Technology have developed a more efficient way to produce the fuel needed to keep fuel cells going — namely, hydrogen. We’ve been giving hydrogen the stinkeye because it is sourced primarily from fossil natural gas, but the Eindhoven solution works on solar energy and water, and gallium phosphide aka GaP. The artificial leaf that could power the world. As Daniel Nocera gazed down on one of his experiments in what has come to be known as the "holy grail" of energy research, his response was to shrug: "Oh, that can't be right.
" It was a glass of tap water with a thumb-sized strip of silicon floating in it. When he held the glass up to the light, the strip began to gently bubble. It seemed to be splitting water into hydrogen and oxygen. Plant-e Modular. The modular system is the first product that Plant-e introduced to the market (launched in 2014). One system consists of 100 square meter modules equipped with our technology and plants. Plant-e's modular system is suitable for small to medium scale applications. It can be applied in sizes of (multiples) 100m2 to be used for LED-lighting, power a WiFi-spot or function as a green roof while generating electricity for the building underneath. In the last case the system doesn’t only generate electricity, but adds other advantages such as insulation, water storage and increase of biodiversity.
The first two systems worldwide are installed on the Hembrug Grounds in Zaandam, and on the Food Innovation Strip connecting the municipalities of Ede and Wageningen (both in The Netherlands). Artificial Photosynthesis Yields Valuable Chemicals. Tiny semiconductors and bacteria have been combined to create a system that uses sunlight to turn carbon dioxide into valuable chemicals. Photosynthesis forms the basis of most life on Earth.
However, it cannot draw carbon dioxide out of the atmosphere fast enough to match the rate at which we are releasing what was stored over millions of years. This has led to a quest to produce an artificial and more efficient version – ideally one that would turn the carbon into something we can easily use. Recently, there has been a lot of work based around the idea of combining bacteria with manufactured materials. The Lawrence Berkeley National Laboratory has announced what team leader Professor Peidong Yang calls “a revolutionary leap forward” in this area. "Our system has the potential to fundamentally change the chemical and oil industry in that we can produce chemicals and fuels in a totally renewable way, rather than extracting them from deep below the ground,” says Yang.

German car manufacturer Audi has reportedly invented a carbon-neutral diesel fuel, made solely from water, carbon dioxide and renewable energy sources. And the crystal clear 'e-diesel' is already being used to power the Audi A8 owned by the country’s Federal Minister of Education and Research, Johanna Wanka. The creation of the fuel is a huge step forward for sustainable transport, but the fact that it’s being backed by an automotive giant is even more exciting. Audi has now set up a pilot plant in Dresden, Germany, operated by clean tech company Sunfire, which will pump out 160 litres of the synthetic diesel every day in the coming months.
