47 Entries from 7 Countries Compete to Convert CO2 into Valuable Products; World Leading Chemical, Biomolecular and Energy Experts to Advise in Global Innovation Challenge

LOS ANGELES (July 27, 2016) XPRIZE, the world’s leader in designing and managing incentive competitions to solve humanity’s grand challenges, today announced a total of 47 entries from seven countries will contend to win the $20M NRG COSIA Carbon XPRIZE, a global competition to develop breakthrough technologies that convert the most CO2 into one or more products with the highest net value. Competing teams hail from Canada, China, India, Finland, Switzerland, Scotland and the United States. An Advisory Board of nine leading experts in the fields of chemical and biological engineering, energy and sustainability and public policy, also announced today, will advise the Carbon XPRIZE.

The NRG COSIA Carbon XPRIZE, launched in September 2015, addresses global CO2 emissions by incentivizing innovative solutions to convert CO2 from a liability into an asset. The 4-½ year competition will include two tracks, with the new technologies tested at either a coal power plant or a natural gas facility. Among the teams competing are leading carbon capture technology companies, top-tier academic institutions, non-profits, new startups and even a father and son team. A complete listing of teams competing in Round 1 is posted on the XPRIZE site.

“These teams, as well as our advisory board, represent an exciting mix of talent with expertise across a broad spectrum of sciences that will be applied to create technologies that mitigate CO2 emissions globally,” said Paul Bunje, Ph.D., principal and senior scientist, Energy and Environment group at XPRIZE. “Such widespread interest and support demonstrates an unwavering global commitment to take a radical leap forward to address climate change.”

“NRG’s sponsorship of XPRIZE accelerates the development and use of carbon capture technologies that help to address climate change,” said Ben Trammell, SVP, Engineering & Construction at NRG. “By crowdsourcing the best minds, XPRIZE and its sponsors are transforming a waste product and cleaning the planet. This prize gets a much-needed dialogue started with experts from around the world, with diverse backgrounds, all to help turn CO2 into a positively viewed byproduct.”

“The Carbon XPRIZE is harnessing global innovators to reimagine carbon and change it from a liability into a resource, from a waste into a valuable product. As a scientist, I know from experience that when you focus a challenge and incentivize smart people to think about how to address that challenge from different angles and different perspectives, good things happen,” said Dan Wicklum, COSIA chief executive. “COSIA is excited about what’s going to come out of this challenge – good things are going to happen.”

The $20M NRG COSIA Carbon XPRIZE features three rounds of competition. In Round 1, each team submitted project documents surrounding technical and business viability assessments of its approach, and independent panel judging underway. Up to 15 semi-finalist teams in each track are scheduled to be announced on Oct. 15, 2016. Round 2 enables teams to demonstrate their technologies in a controlled environment using a simulated power plant flue gas stream, with up to five teams in each track moving forward and sharing a $2.5 million milestone purse. The third round entails larger scale technology demonstration under real world conditions, with access to two test centers adjacent to existing power plants. In each track, the winner will be awarded a $7.5 million grand prize.

In addition to finalizing the overall competitor pool, the Carbon XPRIZE announced the formation of an advisory board of academic and industry experts that bring diverse expertise in their fields. The advisory board includes:

Graphene oxide sheets to transform dirty water into drinking water

Graphene oxide has been hailed as a veritable wonder material; when incorporated into nanocellulose foam, the lab-created substance is light, strong and flexible, conducting heat and electricity quickly and efficiently.

Now, a team of engineers at Washington University in St. Louis has found a way to use graphene oxide sheets to transform dirty water into drinking water, and it could be a global game-changer.

“We hope that for countries where there is ample sunlight, such as India, you’ll be able to take some dirty water, evaporate it using our material, and collect fresh water,” said Srikanth Singamaneni, associate professor of mechanical engineering and materials science at the School of Engineering & Applied Science.

The new approach combines bacteria-produced cellulose and graphene oxide to form a bi-layered biofoam. A paper detailing the research is available online in Advanced Materials.

“The process is extremely simple,” Singamaneni said. “The beauty is that the nanoscale cellulose fiber network produced by bacteria has excellent ability move the water from the bulk to the evaporative surface while minimizing the heat coming down, and the entire thing is produced in one shot.

“The design of the material is novel here,” Singamaneni said. “You have a bi-layered structure with light-absorbing graphene oxide filled nanocellulose at the top and pristine nanocellulose at the bottom. When you suspend this entire thing on water, the water is actually able to reach the top surface where evaporation happens.

“Light radiates on top of it, and it converts into heat because of the graphene oxide — but the heat dissipation to the bulk water underneath is minimized by the pristine nanocellulose layer. You don’t want to waste the heat; you want to confine the heat to the top layer where the evaporation is actually happening.”

The cellulose at the bottom of the bi-layered biofoam acts as a sponge, drawing water up to the graphene oxide where rapid evaporation occurs. The resulting fresh water can easily be collected from the top of the sheet.

The process in which the bi-layered biofoam is actually formed is also novel. In the same way an oyster makes a pearl, the bacteria forms layers of nanocellulose fibers in which the graphene oxide flakes get embedded.

“While we are culturing the bacteria for the cellulose, we added the graphene oxide flakes into the medium itself,” said Qisheng Jiang, lead author of the paper and a graduate student in the Singamaneni lab.

“The graphene oxide becomes embedded as the bacteria produces the cellulose. At a certain point along the process, we stop, remove the medium with the graphene oxide and reintroduce fresh medium. That produces the next layer of our foam. The interface is very strong; mechanically, it is quite robust.”

The new biofoam is also extremely light and inexpensive to make, making it a viable tool for water purification and desalination.

“Cellulose can be produced on a massive scale,” Singamaneni said, “and graphene oxide is extremely cheap — people can produce tons, truly tons, of it. Both materials going into this are highly scalable. So one can imagine making huge sheets of the biofoam.”

“The properties of this foam material that we synthesized has characteristics that enhances solar energy harvesting. Thus, it is more effective in cleaning up water,” said Pratim Biswas, the Lucy and Stanley Lopata Professor and chair of the Department of Energy, Environmental and Chemical Engineering.

“The synthesis process also allows addition of other nanostructured materials to the foam that will increase the rate of destruction of the bacteria and other contaminants, and make it safe to drink. We will also explore other applications for these novel structures.”

Growing graphene – blue sky research attempts to replicate nature

Growing graphene – blue sky research attempts to replicate nature

A ground-breaking experiment at The University of Nottingham could herald the production of high-purity, large-area graphene and boron nitride layers in a controlled way. If successful this research could unlock the full potential of graphene in electronics and optoelectronics.

Ten years after the discovery of graphene by the Nobel Prize winning research team at The University of Manchester, Sergei Novikov, Professor of Physics and his co-investigators at Nottingham secured funding to build a custom made Molecular Beam Epitaxy (MBE) machine capable of the high temperatures required to grow graphene and boron nitride layers on an industrial scale.

Over £2m from the Engineering and Physical Sciences Research Council, The University of Nottingham and the Leverhulme Trust, has been invested in the design, purchase and running costs of the world’s hottest MBE machine. The new facility in the School of Physics and Astronomy will be officially opened at 11am on Thursday 8 January 2015.


Invest In Graphene

Invest In Graphene

Graphene is perhaps the single most exciting material known to man. It is, so to speak, a material full of promise. It is likely to transform the world in which we live and it is likely to make many people very rich. Those who invest in graphene in the earliest phases of the development cycle stand to make the most from this modern wonder; and so, to invest in graphene now has to be an absolute no-brainer.

For those who want more than just an idle speculation written on the back of a napkin I suggest you consider a recent report from IdTechEx, which forecasts that sales of graphene will reach the 100 million dollars mark by 2018; this from a product that has, at the time of writing, hardly reached the High Street.

What are the benefits of investing in graphene?

Such sales forecasts are based on the versatility of the material and the potential for its incorporation into almost anything. It has already been used to make conductive inks, sports equipment and the hulls of boats, but its true potential is inexcusably vast. Expect to see graphene featuring in smart packaging, super capacitors, composites, ITO replacement, sensors, as well as in the energy industry. Graphene is absolutely set to transform our world.

In which graphene companies should you invest?

So, for those people wishing to invest in graphene, where is the best place to turn? Well, a number of companies are very prominently involved in the development of the nano-material and in researching its capabilities. Many of the big technology companies have a vested interest in the material, as few can afford to be left behind, and some lesser known specialists operating within the nanotechnology field, largely start-ups that have grown out of university research units, are also developing a presence. Choosing which  to invest in is, however, no easy thing.

To make things slightly easier it is possibly worth deciding upon a sector of the industry and researching the companies that operate within it. Knowing a little about the science can also help to uncover those companies likely to adopt graphene technology in the future. For now, however, it is perhaps enough to think about the production phase of the industry.

When considering production it is worth knowing that graphene is produced by a number of methods, the two most developed being exfoliation and chemical vapour deposition (hereafter referred to as CVD). Each method produces a slightly different form of the material and each form has the potential to be used for different things. Exfoliating graphene, the cheaper of the two production methods, results in small islands of bilayer product that can be incorporated into energy storage devices, composite building materials,etc. Higher grade CVD graphene is much more expensive to produce but has the potential for use as a replacement for indium tin oxide in the manufacture of smart phones and electronic devices. As someone looking to invest in graphene it would be wise to research each production method and explore the opportunities therein.

A good place to begin your research would be Grafoid, GrafTechCVD Equipment Corporation and Oxford Instruments. These companies all have an involvement in the graphene industry whether it be in the direct production of the material or in the supply of the specialist technology required for its production.
