100% Renewable Energy Vision

Can the United States convert to 100 percent clean, renewable energy by 2050? Stanford University’s Mark Z. Jacobson and U.C. Berkeley’s Mark Delucchi certainly think so. In fact, they’ve laid out a very comprehensive plan to do just that.

The two researchers have recently published a study detailing the viability of the U.S. converting to 100 percent green energy. They’re calling for aggressive changes in both infrastructure and energy consumption on a state-by-state level to achieve this goal. The new study shows that this transition from fossil fuels to renewable resources is not only technically possible with already existing technologies, but it’s also economically feasible.

“The main barriers are social, political and getting industries to change. One way to overcome the barriers is to inform people about what is possible,” Jacobson said. “By showing that it’s technologically and economically possible, this study could reduce the barriers to a large scale transformation.”

Engineering Stretchable Batteries

Recently, scientists have been looking at the Japanese paper-folding art of origami as inspiration for novel flexible energy-storage technologies. While there have been breakthroughs in battery flexibility, there has yet to be a successful development of stretchable batteries. Now, researchers from Arizona State University have unveiled a way to make batteries stretch, yielding big potential outcomes for wearable electronics.

The Arizona State University research team includes ECS member and advisor of the ECS Valley of the Sun student chapter, Candace K. Chan. Chan and the rest of the team were inspired by a variation of origami called kirigami when developing this new generation of lithium-ion batteries.

According to the researchers, the new battery can be stretched more than 150 percent of its original size and still maintain full functionality.

Scientists have developed a small-scale device that can aid in the advancement of artificial photosynthesis and fuel cell technologies.

The new device provides an easy “plug-and-play” microfluidic test-bed to evaluate materials for electrochemical energy conversion systems. Researchers will now be able to test small amounts of molecules and materials before producing a full-scale device to insure new devices will provide high energy density.

Sophia Haussener and Joel Ager, published ECS authors and past members, were two of the researchers that worked on the project for the U.S. Department of Energy. (Check out Haussener’s past research on photoelectrochemical water-splitting and Ager’s work in electron diffraction.)

This from U.S. Department of Energy:

As all functional components in this microfluidic test-bed can be easily exchanged, the performance of various components in the integrated system can be quickly assessed and tailored for optimization. The initial experiments and modeling were performed for water electrolysis; however, the system can be readily adapted to study proposed artificial photosynthesis and fuel cell technologies.

The researchers believe that this technology will be easily adaptable to other technologies, such as solar-fuel generators. Development of such devices may significantly accelerate due to the new ability to assess performance at an early stage.

Wind energy has seen a lot of positive momentum over the past few years in a global effort to help facilitate change in the energy infrastructure. With over $100 billion invested in wind energy in 2014 alone, this technology is one of the fastest growing sectors in the world. Today we’re celebrating Global Wind Day by looking at the innovation that has happened in this sector and taking a peek at what is yet to come.

Over the years, wind energy has seen some dramatic changes. In the 1980s, California was the hub of all wind energy with 90 percent of the world’s installed wind energy capacity. Now, countries such as China, Germany, Spain, India, and the United States have all shifted a substantial percentage of energy needs toward wind. In just a short 12-year period between 2000 and 2012, wind energy has increased over 16 times to more than 282,000 MW of operating wind capacity.

Scientists across the globe are continuing to tap into this technology in order to produce higher efficiency levels at lower price points. Take a look at the work some of our scientists are doing in the sector:

Printable Functional Materials

Potential technical applications of printable functional inks.

The video and information in this post relate to an ECS Journal of Solid State Science and Technology focus issue called: Printable Functional Materials for Electronics and Energy Applications.

(Read/download the focus issue now. It’s entirely free.)

Printing technologies in an atmospheric environment offer the potential for low-cost and materials-efficient alternatives for manufacturing electronics and energy devices such as luminescent displays, thin-film transistors, sensors, thin-film photovoltaics, fuel cells, capacitors, and batteries. Significant progress has been made in the area of printable functional organic and inorganic materials including conductors, semiconductors, and dielectric and luminescent materials.

These new printable functional materials have and will continue to enable exciting advances in printed electronics and energy devices. Some examples are printed amorphous oxide semiconductors, organic conductors and semiconductors, inorganic semiconductor nanomaterials, silicon, chalcogenide semiconductors, ceramics, metals, intercalation compounds, and carbon-based materials.

A special focus issue of the ECS Journal of Solid State Science and Technology was created about the publication of state-of-the-art efforts that address a variety of approaches to printable functional materials and device. This focus issue, consisting of a total of 15 papers, includes both invited and contributed papers reflecting recent achievements in printable functional materials and devices.

The topics of these papers span several key ECS technical areas, including batteries, sensors, fuel cells, carbon nanostructures and devices, electronic and photonic devices, and display materials, devices, and processing. The overall collection of this focus issue covers an impressive scope from fundamental science and engineering of printing process, ink chemistry and ink conversion processes, printed devices, and characterizations to the future outlook for printable functional materials and devices.

Dr. Alvin Salkind Dies at Age 87

Dr. Alvin Salkin with Roque Calvo

Dr. Alvin Salkind with ECS Executive Director Roque Calvo at ECS headquaters May 19, 2015.

We have some very sad news. Long time ECS member, Dr. Alvin Salkind has died. He joined The Electrochemical Society in 1953 and continued as a member in good standing for more than 62 years.

This message from his family:

Dear ECS Society members,

We are sad to let you know that our father, Dr. Alvin J. Salkind, a fellow of the Electrochemical Society, passed away on Tuesday at the age of 87. Funeral services will be on Friday, June 12 at 10am at the Mather-Hodge Funeral Home, 40 Vandeventer Ave., Princeton NJ 08542. All are welcome to join us to celebrate his life and career.

James and Susanne

The first thing you need to know is that Dr. Salkind literally wrote the books on electrochemistry and alkaline batteries: Techniques of Electrochemistry Vol 1-3 with Ernest Yeager and Alkaline Storage Batteries with S. Uno Falk.

The ECS Digital Library will give you an idea of how important he was.

To say he was a friend of the Society is an understatement. He lived near the home office and made frequent visits. The picture above is from his latest visit. He was just here May 19th so Roque Calvo, ECS Executive Director, could interview him on video about his life (we’ll have that video soon). He was a pleasure and had lots of great stories.

Below is just a little from notes we gathered from the research we dug up from various sources about Dr. Salkind as we planned for the video interview:

The revolutionary system can harvest energy from living plants for use in isolated villages.
Image: Plant-e

A revolutionary system with the potential to affect global energy harvesting has recently been developed by a company called Plant-e. The system generates electricity from water-logged plants such as rice grown in patty fields to collect and distribute energy to all areas, even desolate villages.

“It’s based on the principle that plants produce more energy than they need,” said Marjolein Helder, co-founder of Plant-e. “The advantage of this system over wind or solar is that it also works at night and when there’s no wind.”

The science behind the Plant-e technology was conceptualized at Wageningen University in 2007, with the company’s establishment happening thereafter in 2009.

Simply find a plant growing in water and the Plant-e system can begin to harvest energy—whether that plant be rice growing in paddies or simply something growing in your garden.

“It’s just the beginning and lots of things still need to be greatly improved, but the potential is enormous,” said Jacqueline Cramer, professor of sustainable innovation at Utrecht University and former Dutch environment minister.

One of the roadblocks in developing a new, clean energy infrastructure lies in our ability to manufacture solar cells with ease and efficiency. Now, researchers from Rice University may have developed a way to simplify this process.

In Andrew Barron’s Rice University lab, he and postdoctoral student Yen-Tien Lu are developing black silicon by employing electrodes as catalysts.

The typical solar cell is made from silicon. By swapping that regular silicon for black silicon, solar cells gain a highly textured surface of nanoscale spikes that allows for a more efficient collection of light.

This from Rice University:

Barron said the metal layer used as a top electrode is usually applied last in solar cell manufacturing. The new method known as contact-assisted chemical etching applies the set of thin gold lines that serve as the electrode earlier in the process, which also eliminates the need to remove used catalyst particles.

Engineers from the University of Illinois at Urbana-Champaign’s College of Engineering have developed a high-performance 3D microbattery applicable for large-scale on-chip integration with microelectronic devices.

“This 3D microbattery has exceptional performance and scalability, and we think it will be of importance for many applications,” said Paul Braun, professor of materials science and engineering at Illinois.

“Micro-scale devices typically utilize power supplied off-chip because of difficulties in miniaturizing energy storage technologies. A miniaturized high-energy and high-power on-chip battery would be highly desirable for applications including autonomous microscale actuators, distributed wireless sensors and transmitters, monitors, and portable and implantable medical devices.”
