The Illinois Institute of Technology is one of ECS’s newest student chapters, and they held their first event on November 23, 2015. They received an excellent attendance rate of nearly one hundred students in addition to IIT faculty members and faculty from other near by institutions.  This event included the director of the Argonne Collaborative Center for Energy Storage Science (ACCESS), Dr. Jeffrey Chamberlain, who is also the deputy director of the Joint Center for Energy Storage Research (JCESR). Dr. Chamberlain hosted a lecture that included information and a detailed analysis on the innovation of battery technologies.

Following the lecture, a Q&A session was held, which gave the students and faculty in attendance the opportunity to address questions produced from Dr. Chamberlain’s lecture. These questions included the topics of environmental issues, the life cycle of lithium ion batteries, development of lithium-air batteries and even government policy and funding. The formal lecture and Q&A session was followed with refreshments and continued discussion. The IIT student chapter is extremely grateful to Dr. Chamberlain for taking the time out of his very busy schedule to come and interact with the chapter at their first event.

Congratulations, IIT Student Chapter on a very successful kick-off event!

The Low-Hanging Fruits of Energy

When examining climate change and energy conservation, minds often tend toward large-scale grid technologies. While solar technologies and energy storage systems are big end goals, researcher from Iowa State University state that there are intermittent steps that should be considered.

“Many people consider energy efficiency to be the low-hanging fruit,” says Yu Wang, who studies global energy policy and energy efficiency at Iowa State University. “If you’re facing the target of trying to mitigate climate change, energy efficiency should be the first choice because it’s cheap and easy in comparison with other options.”

Importance of Energy Conservation

For Wang and others, replacing old incandescent bulbs with LED lighting is an important step in energy conservation. While it may seem like a move this small would have no impact on the overall energy consumption of the country, Wang and other researchers estimate the swap could yield an electrical savings of 10.2 percent by 2035.

Another step toward a more energy efficiency society deals with policy at all levels.

“In general [the future of renewable energy] is really up to the politicians to change the energy infrastructure,” says John A. Turner, National Renewable Energy Laboratory. “We have pretty much all the technologies we need. We certainly need to be able to upscale them and get things cheaper, but the issue is how do you replace an essentially established infrastructure with a new one? You need political support.”

Solar Geoengineering and Climate Change

The Earth is getting warmer and greenhouse gas emissions are on the rise. With carbon dioxide levels at their highest in 650,000 years, scientists across the global are grappling with the question of how to stop global warming.

For many, alternative energy sources are the answer. While the implementation of this technology is crucial for the development of a carbon-free society, flipping the grid is easier said than done. The U.S. alone is highly dependent on fossil fuels, which emit high level of greenhouse gases. Additionally, transitioning the grid to 100 percent renewables would not fully solve the issue. Emissions will still exist in the atmosphere, with warming happening right now.

“When people emerge from poverty and move toward prosperity, they consume more energy,” said Adam Heller in a recent plenary lecture.

The Need for a Solution

Currently, 13 percent of carbon dioxide emissions stem from two industries: steel and cement. According to Heller, these industry are directly correlated to global wealth—what he deems the driving force of acceleration in climate change. To put that in perspective, the solar energy technology that is currently in place in the U.S. saves only 0.3 percent through the use of solar energy, according to Heller. With carbon dioxide emissions constantly accelerating, increasing by 2 percent every year, scientists are looking for solutions to this pressing issue.

“This will lead to a catastrophe,” Heller said. “The question is, what do we do about this catastrophe?”

For Heller and other scientists, part of the answer lies in solar geoengineering (SGE).

“We need to learn something about geoengineering,” Heller said. “We need to learn something about reflecting light from the sun through aerosols in the atmosphere.”

Solving Climate Change with Bubbles

In light of U.N. Climate Talks in Paris and the crippling air pollution levels in China, Bill Nye continuing the good fight against climate change with his latest pitch for a solution against the catastrophic force.

His possible solution? Bubbles.

Through a simple experiment, Nye explores the possibility of purposely inducing bubbles to potentially help satisfy water and sanitation demands as well as reflect light into space—helping control the global temperature.

In the full interview with Yahoo! News Live, Nye also discusses a carbon fee, the real threats of climate change, and “climate deniers.” Check out the full video.

Advances in Sodium Batteries

With energy demands increasing every day, researchers are looking toward the next generation of energy storage technology. While society has depended on the lithium ion battery for these needs for some time, the rarity and expense of the materials needed to produce the battery is beginning to conflict with large-scale storage needs.

To combat this issue, a French team comprised of researchers primarily from CNRS and CEA is making gains in the field of electrochemical energy storage with their new development of an alternative technology for lithium ion batteries in specific sectors.

Beyond Lithium

Instead of the rare and expensive lithium, these researchers are focusing on the use of sodium ions—a more cost efficient and abundant materials. With efficiently levels comparable to that of lithium, many commercial sectors are showing an increasing interest for sodium’s potential in storing renewable energy.

While this development takes the use of sodium to a new level, the idea has been around since the 1980s. However, sodium never took off as the primary battery building material due to low energy densities and short life cycles. It was then that researchers chose to power electronics with lithium for higher efficiency levels.

Reducing Carbons, Producing Fuels

The effort to harvest atmospheric carbons and transform the greenhouse gases into renewable fuels has taken one step closer to practicality due to new research out of Monash University.

Through the novel combination of cheap materials to develop an energy efficient catalyst, the researchers believe they could electrochemically reduce carbon dioxide into syngas. This produced syngas would be comprised of a combination of carbon monoxide and hydrogen—the elements widely used as the starting point to produce sustainable fuels and materials.

“Our research found that a combination of cheap materials—Molybdenum Sulphide catalytic nano-particles with a conductive layer of graphene and a well-known polymer called polyethylenimine acted together to create this energy efficient catalyst. Each component in the catalyst played a specific role in the reaction and it was only when the three were combined that the energy efficiency of the process was realized,” said Jie Zhang, lead author of the study.

Nanoporous Materials and Global Warming

In a practical effort to address climate change, researchers are looking at the possibility to capture harmful greenhouse gasses and transforming them into something useful for society. Recently, researchers from the University of South Carolina started exploring this topic, opening the door for more research in green fuels produced by carbon. Now, a team from the University of South Australia is taking that concept and applying nanoporous carbon nitride to help solve global warming.

With carbon dioxide levels at their highest in 650,000 years, scientists are developing innovative ways to help contain the greenhouse gas. The team at the University of South Australia, led by Ajayan Vinu, is working to capture and convert carbon dioxide molecules with the help of nanoporous materials.

“Their interesting properties—a semiconducting framework structure and ordered pores—make them exciting candidates for the capture and conversion of [carbon dioxide] molecules into methanol which can then be used as a source of green energy with the help of sunlight and water,” Vinu said.

Lithium ion batteries affect everything from small electrical devices to airplanes, yet the battery’s aging process creates limitations to storage capacity. While researchers have not yet been able to determine what causes aging in lithium ion batteries, a research team has made new developments to offer more insight to this downfall and potentially create more youthful batteries.

The study, recently published in the Journal of The Electrochemical Society (JES), describes newly discovered factors that speed up the aging process in lithium ion batteries. This research is especially important in light of efforts in renewable energy, where this energy storage technology could be interwoven with the grid to help bolster efforts in wind and solar.

This from a press release:

The research group determined two key mechanisms for the loss of capacity during operation: The active lithium in the cell is slowly used up in various side reactions and is thus no longer available. The process is very temperature dependent: At 25 °C the effect is relatively weak but becomes quite strong at 60 °C. When charging and discharging cells with a higher upper cut off potential (4.6 V), cell resistance increases rapidly. The transition metals deposited on the anode may increase the conductivity of the pacifying layer and thereby speed up the decomposition of the electrolyte.

Powering Batteries in Harsh Environments

Researchers across the globe have been investing more and more effort into developing new materials to power the next generation of devices. With the population growing and energy demands rising, the need for smaller, faster, and more efficient batteries is more prevalent than ever.

While some researchers are attempting to develop complex material combinations to tackle this issue, researchers from Rice University are going back to basics by developing a clay-based electrolyte.

Utilizing clay as a primary material in a lithium ion battery could address current issues that the battery has with high temperature performance. With clay, the researchers were able to supply stable electrical power in environments with temperatures up 120°C. The addition of clay to the electrode could allow lithium ion batteries to function in harsh environments including space, defense, and oil and gas applications.
