ECS Vice President Johna Leddy is an established researcher in electrochemical power sources and a highly respected mentor to the students of the Leddy Lab. Always the educator, Leddy’s most recent side project was creating a door plaque that explains her research to those passing by at the university (see below). The Venn diagram pictured on right is featured (click on it to expand). Leddy explains herself:

The Venn diagram is a map of my research at the current time. Energy and electrocatalysis are at the center and various things evolve from there. Largely, we focus on unusual ways to electrocatalyze reactions that are important in energy generation and storage.

The unusual means of electrocatalysis include: introduction of micromagnets on the electrode to increase rates of electron transfer; use of ultrasound in a thin layer to activate the electrode surface; and modification of electrodes with algae to make ammonia.

At the edges of the Venn diagram are places where these fundamental studies are implemented in energy technologies and voltammetric analysis. The bottom ring is a list of the tools that we use. It all ties together: theory and fundamentals to experiments to devices and back to theory. Experiments inform theory and devices, that lead to questions that generate more experiments.

In a push for more basic research funding for electrochemical science, past ECS President Daniel Scherson testified before a U.S. House subcommittee to discuss innovations in solar fuels, electricity storage, and advanced materials.

“I want them to understand where electrochemistry fits in many aspects of our lives,” Scherson, the Frank Hovorka Professor of Chemistry at Case Western Reserve University, said prior to the hearing.

During the hearing, Scherson emphasized to the subcommittee that in order to solve some of society’s most pressing problems, more federal funding to basic electrochemistry research is critical. He further explained that without efforts in electrochemistry, nearly all aspects of energy storage and conversion – including batteries, fuels cells, EVs, and wind and solar energy – would cease to be viable.

“Electrochemistry is a two century old discipline that has reemerged in recent years as a key to achieve sustainability and improve human welfare,” Scherson told the subcommittee.

In recent years, budget cuts in federal spending have adversely affected scientific research. In April of this year, Sen. Jeff Flake (R-Ariz.) launched an attack on federal research dollars in the form of the Wastebook – a report detailing specific studies that the senator believes to be wasteful spending.

Michael Faraday is a household name to those in the science, but the breadth and depth of his pioneering work is sometimes overlooked in lieu of modern day developments. In an effort to preserve and highlight the enormous impact of Faraday’s work, the UNESCO has announced that the pillar of electrochemistry’s notebooks (held by the Royal Institution) have been added to the UK Memory of the World Register.

The Memory of the World Register was established in 1992 and is a catalogue of the world’s most prized documentary and audiovisual heritage. Faraday’s notebooks will join the ranks of documents such as the Magna Carta and the Death Warrant of King Charles I.

The significance of notebooks lies in Faraday’s documentation and development of some of the most important physical and chemical discoveries of the 19th century. Many have referred to Faraday as one of the greatest experimentalists ever, especially due to his work on electricity that found expression in day-to-day technology. His work on electromagnetic rotations and induction transformed electrical devices as we know them, opening the door for the development of motors, transformers, and generators.

University of Iowa researchers have teamed up with California-based startup HyperSolar to progress the science in producing clean energy from sunlight and water. The goal of this research is to develop a way to efficiently and sustainably produce low-cost renewable hydrogen for commercial use.

Hydrogen has huge potential as an alternative form of energy. According to the U.S. Energy Information Administration, hydrogen has the highest energy content of any fuel we use today (carbon dependent fuels included).

But hydrogen is not a naturally occurring element on this planet, so it needs to be produced. Currently, most hydrogen is produced via steam reforming – a process using fossil fuels and creating carbon dioxide. While the end produce is clan, renewable energy, the means of getting to that product were carbon dependent. The new study hopes to help move hydrogen production away from the traditional means of creation and toward electrolysis, which requires only electricity and water to create hydrogen.

“Developing clean energy systems is a goal worldwide,” says Syed Mubeen, HyperSolar’s lead scientist and chemical engineering professor at the University of Iowa. “Currently, we understand how clean energy systems such as solar cells, wind turbines, et cetera, work at a high level of sophistication. The real challenge going forward is to develop inexpensive clean energy systems that can be cost competitive to fossil fuel systems and be adopted globally and not just in the developed countries.”

Lithium based technologies have been dominant in the battery arena since Sony commercialized the first Li-ion battery in 1991. ECS member Jeff Ortega, however, believes that a different material holds more promise than its lithium competitor in the world of microbattery technology.

During the 229th ECS Meeting, Ortega presented work that focused on the analysis of data from commercially available rechargeable Li-ion and Li-polymer cells. He then compared the silver-zinc button cells of ZPower, where he currently serves as the company’s director of research. His results showed that the company’s silver-zinc button cells offer both greater capacity and greater density than their Li-ion and Li-polymer counterparts. Additionally, Ortega stated that the cells are also generally safer and better for the environment.

According to Ortega, the small silver-zinc cells have 57 percent greater energy density than both types of lithium based calls. Their potential applications including medical devices, body worn sensors, wearables, and any other microbattery application that demands long wear time. Currently, ZPower has implement these cells in hearing aid technologies.

“The ZPower Rechargeable System for Hearing Aids makes it easy to convert many new and existing hearing aids to rechargeable technology,” says Ortega in a statement. “The Rechargeable System offers a full day of power, charges overnight in the hearing aids, takes the place of an estimated 200 disposable batteries and lasts a full year. The ZPower hearing aid battery is replaced once per year by a hearing care professional, so the patient never has to touch a hearing aid battery again.”

Fossil fuel prices may be dropping, but according to new reports from Bloomberg’s New Energy Outlook, those prices will not affect the future of renewable energy.

According to the report, renewables are on pace to attract $7.8 trillion in investments by 2040. That’s nearly four times the amount that Bloomberg expects carbon-based power to attract over the same period of time.

Experts expect the relatively low fossil fuel prices to by offset by projected price drops of up to 60 percent in wind and solar technologies, making renewables the most efficient and most affordable option.

“Strikingly, [the report] still shows rapid transition toward clean power,” says Jon Moore, chief executive of Bloomberg New Energy Finance.

However, that transition may not be fast enough to counteract the effects of climate change. In order to keep the global temperate change below 2°C – a point that was emphasized in the Paris agreement – an additional $5.3 trillion would have to be invested in zero-carbon power on top of the $7.8 trillion.
