Recently, I had the opportunity to visit the Energy Department’s National Renewable Energy Laboratory (NREL) for an alumni meeting of the Executive Energy Leadership Academy (Energy Execs), a program that empowers executives to integrate clean energy solutions in their own communities.

Since its inception, more than 200 representatives of industry, government and non-profit organizations have completed the Energy Execs program, delivered through the Executive Energy Leadership Academy. In 2014, I participated in the abbreviated program which offers decision-makers a look at renewable energy and energy efficiency technologies. As part of the experience, we received briefings by NREL technology experts, research laboratory tours and visits to renewable energy installations.

The Electrochemical Society’s Vilas Pol has developed a new process to turn simple packing peanuts into energy-storing battery components.

Pol, an associate professor at Purdue University and active member of ECS, has thoroughly succeeded in turning one person’s trash into another person’s high-tech treasure. He and his team from Purdue University have developed a system that turns the puffy packing peanuts into nanoparticles and microsheets perfect for rechargeable batteries. Pol’s new generation of battery could even outperform the ones we currently use.

We’ve been hearing about the new generation of vehicles for some time now. The self-driving, autonomous, electric car seemed to be so distant that it transformed into a pipe dream—until now. Tesla CEO Elon Musk announced this past week that Tesla’s self-driving cars will hit highways this summer.

On Thursday March 18, Musk arranged a press conference to talk about Tesla’s automobile software update that will eliminate range anxiety—or the fear that your electric car will run out of power before being able to recharge on long trips.

But that wasn’t the highlight of the press conference. Musk casually announced that beginning around June, all Tesla models well get an update that allows them to drive in “Autopilot” mode.

Edgar’s new patented process will allow for the building of better semiconductors.

The Electrochemical Society’s Jim Edgar has developed a new process to build better semiconductors, which will vastly improve the efficiency of electronic devices and help propel the semiconductor industry.

Edgar, a Kansas State university distinguished professor of chemical engineering and an active member of ECS since 1981, has just received a patent for his “Off-axis silicon carbide substrates” process, which is a way to build a better semiconductor. This new process could mean big things for the electronics and semiconductor manufacturing industries.

“It’s like a stacked cake separated by layers of icing,” Edgar said. “When the layers of semiconductors don’t match up very well, it introduces defects. Any time there is a defect, it degrades the efficiency of the device.”

The tire can generate energy from friction and heat. However, Goodyear has yet to describe the materials to be used.

There’s no question that engineers and manufacturers around the world are moving away from the fuel-based car to the electric vehicle. In order to make these cars possible, they must improve in efficiency. Now, one company is looking outside the box for the answer to electric car sustainability.

Goodyear has just announced the concept of their new tire, which will harvest heat in a variety of ways to help power electric vehicles. The new BH-03 tire is poised to be able to absorb heat while static due to the ultra-black texture of the tire, as well as take advantage of the natural occurrence of friction as the tire moves.

The integration of silk into the lithium-ion battery allowed the battery to work for over 10,000 cycles with only a nine percent loss in stability.

The words “lithium-ion” and “battery” have become almost synonymous recently. While the li-ion battery is used in a multitude of applications, it still does not have a long life without a recharge.

Now, researchers have developed an environmentally friendly way to boost the performance of the li-ion battery by focusing on a material derived from silk.

In the li-ion battery, carbon is the key component for storage. In most situations, graphite takes that role – but it has limited energy capacity. In order to improve the performance of the li-ion battery, researchers looked to replace graphite with a material developed using a sustainable source.

Synthesizing the material as a thin film instead of as a bulk powder opens up new possibilities for fuel cell technology.

Researchers from Cornell University have developed a way to synthesize a new thin-film catalyst to improve efficiency and effectiveness in fuel cells.

For the first time ever, researchers were able to explain the epitaxial thin-film growth of a fundamental electrode component of the fuel cell, which could result in a more effective cathode.

“Up to now, research on oxygen catalysts in thin film form for clean-energy applications has been focused on the perovskite-structured oxides and their structural derivatives,” said lead researcher Araceli Gutierrez-Llorente. “The much less studied cubic pyrochlore structure is an appealing alternative to perovskites for such applications as fuel cell cathodes.”

Researchers have investigated a strategy to prevent this “polysulfide shuttling” phenomenon by creating nano-sized sulfur particles, and coating them in silica (SiO₂), otherwise known as glass.

Lithium-sulfur has been a hot topic in battery technology recently. Because of its ability to produce 10 times the amount of energy as a conventional battery, we’ve seen novel innovations such as the all solid state lithium-sulfur battery. Now, the li-sulfur battery is getting a glass coating to further improve its performance.

Researchers at the University of California, Riverside have applied a glass cage-like coating, along with graphene oxide, to the li-sulfur battery. This innovation was developed in order to overcome one of the major issues in commercializing the battery – polysulfides, which cause the battery’s capacity to decrease over its lifetime.

The cathode material traps the polysulfides in a very thin glass cage. Researchers used an organic precursor to construct the trapping barrier.
