IBM has recently announced that Honda R&D is analyzing and monitoring data via more than 160 sensors in Formula One cars using the Internet of Things (IoT) technology of IBM Watson. This means that crews and drivers can now apply data and analytics in real-time to improve fuel efficiency, streamline performance and enable drivers to make racing decisions based on this information.

The racing world, which is known for split-second reactions by drivers that can make or break the race, has been bringing entertainment to people around the world for almost a century now, where engineers are retrieving data after each race, such as fuel flow and timing, to adjust their strategies for the next race.

But with this new technology, F1 racing has evolved to one that is highly driven by data, where drivers are always being connected and teams being able to analyze the fast vehicles and driver data, and adjust racing strategies in real-time, a critical factor that can help them win races.

Also, the Fédération Internationale de l’Automobile (FIA), a body that governs F1 racing, published new regulations in 2014 requiring all these machines to use hybrid engines and to limit fuel consumption during races, which encourage racing teams to focus on developing more energy-efficient technologies for these cars.

To help mark their return to F1 racing and reach a new milestones in efficiency for both consumer and race cars, Honda R&D developed a new technology, known as power units, to analyze data from hybrid engines, check residual fuel levels efficiently and quickly, and to estimate the possibility of mechanical problems. The company has made it happen using the IBM Watson IoT technology to generate data from the cars, including pressure levels, power levels and temperature, directly to the cloud for real-time analysis.

“Honda R&D is thrilled to work with IBM to mark its return to F1 racing, applying advanced IoT technologies to help ensure our drivers and teams are constantly connected,” said the chief engineer and manager of the Power Unit Development Division of Honda R&D, Satoru Nada. “We are bringing excitement to fans worldwide around the performance of our vehicles and drivers, with the power of data and real-time analytics becoming a critical factor in winning races.”

Now, F1 cars from Honda will be able to recover or save energy to use later during the race for more power. While a race takes place, data is being streamed to the cloud and shared with the racing team and the pit crew, who are equipped with mobile technology. The data is being analyzed in real-time by Honda R&D’s facility in Japan and the McLaren Honda F1 team in the UK. Data and analysis are then going to be transmitted using IBM Streams, as the race is taking place, allowing the teams to adjust basic metrics and improve vehicle performance. Plus, Honda’s research team will also be able to build cutting-edge performance models to measure energy recovery of the power units, ensuring their longevity.

Harriet Green, the general manager for commerce and education of Watson IoT, said, “We are excited to team with Honda to provide sophisticated cognitive IoT capabilities and analytics to combine data directly from the F1 racing vehicles with other sources, allowing Honda to not only enhance its vehicles that are built for speed, but to also be more friendly to our environment.”

Organic Solar Cells – New World Record Efficiency Reached

 Future Energy  Comments Off on Organic Solar Cells – New World Record Efficiency Reached
Feb 162016
 

Organic photovoltaic solar cells (OPV) such as polymer solar cells are promising but not quite ready for commercial production. Their significantly lower device efficiency and operational lifetime compared with conventional silicon cells posed challenges for mass production.

 

Continuous Innovation at Heliatek

Nevertheless, researchers continue to work out improvements on the basic OPV design, undeterred by the efficiency and lifetime issues of the OPV. German solar technology firm Heliatek did not stop innovating OPV for its solar-powered car despite the discouraging 3% efficiency of the OPV that time, around 2003.

In 2012, the German company claimed world-record of 10.7% conversion efficiency for its OPV, and promised to reach the 15% to 20% efficiency of inorganic solar cells. A year after, Optics Org reported that Heliatek had “pushed the conversion efficiency of its organic photovoltaic (OPV) cells to 12%,” which is equivalent to at least 15% in conventional semiconductor-based cells.

Fast forward to 2016, three years after, the German solar technology company announced a new record of 13.2% conversion efficiency using a multi-junction cell. OPV are gaining more interest in the realm of green energy technology because they are cheaper to produce and are more flexible.

Heliatek further claimed that its latest OPV with 13.2% efficiency exhibit “excellent low light and high temperature behavior” of its inorganic counterpart and can generate power as well as conventional cells with 16% efficiency under real world conditions.

 

Purdue University Research Findings

Much like Heliatek, the engineering professors of Purdue University are conducting a research suggesting a new method for manufacturing inexpensive solar technology.

Researchers, Muhammad Ashraful Alam, Bryan Boudourism, Biswajit Ray, Aditya Baradwaj and Ryyan Khan suggested to keep electron-hole pairs separated so that they don’t recombine and impede current generation. They also suggested to simplify the design of organic solar cells using only one type of polymer, and to produce cells out of purer polymers since they are more efficient.

The US Department of Energy, and the US Air Force are some of the sponsors to the research.

 

Likely Commercialization of OPV

In its latest OPV design, Heliatek combined three kinds of absorbers specifically dedicated to convert green, red and near-infrared light to electricity with more efficiency than ever before. It has only been 13 years since OPV was met with much skepticism, but Heliatek’s new world-record solar cells may just well be the key to cost-effective harnessing and harvesting of sunlight to make electricity.

Heliatek’s super lightweight, flexible and low-cost organic solar cells provides a hint that commercialization of OPV may well be under way. Organic solar cells offer a substantial cost advantage over silicon solar cells, and may be manufactured via roll-to-roll processing like that of newspaper printing.

In the same way, Purdue University researchers are continuing on the study and are working on a new type of solar cells that don’t need bulk heterojunctions. They intend to dig deeper into how OPV operate and to help design more efficient and more affordable organic solar cells.

 

Advancement in Flow Batteries Could Make for a Brighter Future

Researchers have their attention directed on the safe storage and discharge of large amounts of energy, as renewable power becoming more popular these days. Expensive lithium-ion batteries are not doing well, so they are turning to flow batteries, which seem more promising. Now, a major breakthrough on such batteries at the Harvard University has made the future even brighter.

A flow battery was introduced by the same university last year, showing it to store energy in vats of inexpensive chemicals. Its design has been improved using non-toxic chemicals and has been made scalable and cheap. As explained by professor of materials and energy technologies at the Harvard School of Engineering and Applied Sciences, Michael Aziz, “Think about running your home on the electricity from your rooftop solar panels that you get during the day. You need to be able to run that battery for hours before it is drained. Traditional solid electrode batteries are drained within an hour.” This means that you could stack up a lot of batteries to get more energy, but this can quickly become really expensive that it can be difficult to afford.

On the other hand, flow batteries are different by separating the energy storage aspect from the electrode interface that charges the battery or releases the energy. However, these batteries have been expensive due to the precious metals, such as vanadium, they use in the negative solution. But through extensive research, scientists at Harvard found out how to replace vanadium with quinone, but there were still problems with the chemicals, particularly bromine, to be used on the positive side, particularly about toxicity and corrosion.

The issue was resolved by replacing bromine with a much safer chemical called ferrocyanide, which is actually a food additive. According to the Cabot Professor of Chemistry and Materials Science at Harvard, Roy Gordon, this compound is not poisonous. This was supported by Aziz, stating, “Ferrocyanide is a positive electrode material that’s safe and stable in an alkaline solution. [That meant] we had to develop a quinone that was highly soluble and stable in an alkaline solution to match up against ferrocyanide, to make the new battery that we just reported this year.”

With regards to the problem with the ferrocyanide preferring and alkaline over an acidic environment, Mike Marshak, who was working on the project, discovered that quinones could actually be dissolved in an alkaline solution, opening up the world of alkaline electrochemistry.

Now, professors Gordon and Aziz envisioned the technology their team unveiled will be safe, cheap and versatile enough to power up a single-family home or an entire community.

Aziz estimated that it would take about 3 years to develop commercial systems ready for scaling these batteries. As for Gordon, he is seeing the flow battery and its new system to be one of the most exciting discoveries to date, saying, “If our future is going to be sustainable, as a civilization, we need to be able to solve these [energy] problems.” Aziz also expressed his thoughts on this matter, stating, “This is certainly the most exciting thing I’ve worked on because the implications are so global. The greatest challenge facing humanity this century —I’m convinced — is finding the energy to power a civilization of 10 billion people without unacceptable consequences to the environment. Renewable energy is front and center in that challenge, and this could really be a very significant enabler of renewable energy.”
