North Carolina research workers show how water based ‘artificial leaf’ generates electricity

Did you know that a North Carolina State University staff has demonstrated that water gel-based solar devices (called: “artificial leaves”) can act like solar cells to make electricity?

The study has been released on-line inside the Journal of Materials Chemistry by Doctor. Orlin Velev, an Invista Professor associated with Chemical and Bio-molecular Engineering.

The findings prove the idea for making solar cells that more closely imitate nature. They also have the possibility to be cheaper and more environmentally friendly than the existing standard silicon based solar cells.

The bendable products are composed of water-based gel infused using light-sensitive molecules (like plant chlorophyll) coupled with electrodes coated by carbon materials, such as carbon nanotubes or graphite.

Graphene is the basic structural element of a number of carbon allotropes including graphite, carbon nanotubes and fullerenes. Graphene is a one-atom thick planar sheet of carbon atoms that are largely packed in a honeycomb crystal lattice. The title comes from graphite ene; graphite itself consists of a lot of graphene sheets piled together.

The light-sensitive molecules get “excited” by the sun’s rays to create electricity, similar to plant molecules that get excited to synthesize sugar in order to grow.

Dr. Velev says that the research team hopes to “learn how to copy the materials through which nature harnesses solar power.” Although man made light-sensitive molecules can be used, Velev says naturally produced products, like chlorophyll, are also very easily integrated in these products because of their particular water-gel matrix.

Velev even imagines a future where homes could be covered with soft sheets of similar electrical power-generating man-made-leaf pv cells. The concept of biochemically inspired ‘soft’ products for generating electricity may in the future offer an alternative for the present-day solid-state technologies.

Volvo cars made out of batteries?
September 30, 2010, 10:47 am
Filed under: News

With a headline referring to Volvo cars being made out of batteries, you could be forgiven for thinking that Volvo want to make heavy cars made out of recycled lead from batteries.  Instead, Volvo are investigating how to incorporate batteries into the panels. 

Conceivably, the weight saving would be sensational, as well as dealing with difficult packaging problems.  There are likely to be some technical hurdles to overcome.  In the meantime, hats off to Volvo engineers for creative and innovative thinking!

A Fuel Saving Alternative to Hybrid / Electric Vehicles
September 10, 2010, 1:01 pm
Filed under: News

Although perhaps not as glamorous as hybrid or plug-in electric vehicles, improving fuel efficiency in internal combustion engine (ICE) vehicles has an important, if interim, role in reducing carbon emissions, and should be embraced.  This article provides an informative overview of some of the technology used in Ford’s ECOnetic range, and in particular the Focus.  Fuel saving features include auto-start-stop, smart regenerative charging, low tension FEAD (Front End Accessory Drive), improved efficiency power steering system and use of low viscosity lubricants.  Well established fuel saving measures such as low coefficient of drag and low rolling resistance tyres are also mentioned.  In combination with a driver information system (to encourage more efficient driving style) and a turbo diesel ICE, fuel consumption of 3.8L/100km is claimed.  Unfortunately, the very attractive car featured in the photograph is actually badged as the (considerably less economical) RS model; it seems unlikely that the ECOnetic will look as good.

The Surprising ‘Newgencoal’ Website
September 3, 2010, 4:37 pm
Filed under: News | Tags: ,

Readers looking for a interesting, balanced, and attractive website considering a broad range of renewable energy technologies, and the need to tackle climate change, could do a lot worse that to visit http://www.newgencoal.com.au/.

The most surprising thing is that this website is that it is run by the Australian Coal Association. Cynical readers might have expected something defensive or political from such an industry lobby group, this website is anything but.

If only some our politicians who claim to be looking out for the interests of the Australian coal industry were to read this material, they too might realise the need for action on climate change. If the coal industry claims to get it, why don’t our politicians?



Curtin research produces cost effective power sustainably

As a Griffith Hack client we would like to take this opportunity to congratulate Professor Chu-Zhu Li on winning the 2010 Curtin Commercial Innovation Award. Please see details in the Media Release below.

Media Release: 13 August 2010
Curtin University researchers have made a breakthrough in converting biomass, such as mallee, into “clean” combustible gaseous fuels that can be used to generate a continuous source of electricity (base load electricity).

This innovative new technology has the potential to provide a sustainable and economical energy generation alternative, especially in regional and rural areas.

The technology, developed by Professor Chu-Zhu Li and his team from Curtin’s Centre for Advanced Energy Science and Engineering, was named the winner of the 2010 Curtin Commercial Innovation Awards announced today.

The annual awards, run by Curtin’s Office of IP Commercialisation, acknowledge the best commercially-oriented innovations arising from research by Curtin staff and students.

Curtin’s Office of IP Commercialisation Director, Rohan McDougall, said the winning innovation was a great advance in sustainable energy generation.

“The gasifier that Professor Li and his team have developed is able to convert raw solid fuels like biomass into clean gaseous fuel in a highly efficient and economical manner,” Mr McDougall said.

“Numerous efforts have been made worldwide to clean up product gas from existing gasification processes in a cost effective way but with only limited success.

“Use of gasification product gas currently has limitations in electricity generation as tar and other contaminants foul up the gas engines and turbines. Curtin’s gasification technology is able to produce clean product gas with a high energy content.”

The process utilises mallee, abundant in WA and actively farmed to minimise dryland salinity.  Other low-rank fuels like lignite, brown coal and peat can also be converted.

“This technology will be particularly useful in the immediate future in rural and remote areas to replace the diesel engines that are currently being used,” Mr McDougall said.

“Unlike other renewable energy sources this process can be used to produce base load power and not just peak load so eventually when the technology is fully developed it can be used for clean and cost-effective generation of electricity in cities as well.”

A pilot scale gasifier (4kg/hr) has been built and operated successfully.  Professor Li is now working toward the construction of a demonstration plant at Curtin.

Curtin’s Deputy Vice-Chancellor of Research and Development, Professor Linda Kristjanson, commended the winning project.

“This work is an excellent example of the cutting edge research and innovation taking place at Curtin and a very deserving winner of the top prize in this year’s awards,” Professor Kristjanson said.

“Curtin staff and students have an excellent track record in conducting high level, industry-relevant research which can provide significant benefits to the community, with many of the projects offering real commercial potential.”

The other finalists who won prizes at the awards were:

Professor Peter Teunissen
, an ARC Federation Fellow from the Department of Spatial Science at Curtin, was recognised for his next generation global positioning system.  It has improved 3-D positional accuracy, reduced convergence time and improved data integrity. His technology can open up a host of applications that were previously unattainable with existing systems, including precision agriculture, offshore positioning, land surveying, and emergency and military services. 

Dr Fedja Hadzic and Dr Michael Hecker, Research Fellows from Curtin’s Digital Ecosystems Business Intelligence Institute, were awarded an early career prize for a software tool able to clean-up duplications and errors in corporate and government databases. The software can also detect the source of contamination and prevent future data pollution with business process mining.
