Intercalation Pseudocapacitance: A Route Towards Oxide Supercapacitors

Capacitive energy storage offers a number of attractive features including high power capability, fast response times, and long-term cycling.

Toward Fully Renewable Electric Energy Systems

Renewable energy sources are here to stay for a number of important reasons, including global warming and the depletion of fossil fuels. We explore in this presentation how a thermal-dominated electric energy system can be transformed into a renewable-dominated one.

(In)Organic electronics: a world of ubiquitous and crucial interfaces

The potential of organic electronics for relatively cheap and scalable applications in energy conversion, lighting, display, sensing and flexible electronics has been amply demonstrated over the past decade.

Electrochemical Grid Storage: Challenges and Developments

Implementation of new electrical energy storage technologies require major breakthroughs in materials science, chemistry and systems design to further improve performance and cycle life while remaining cost competitive with fossil fuel and other energy storage systems. This presentation presents a broad overview of grid requirements, along with cost effective storage platforms recently supported by ARPA-E.

Charge Dynamics at Interfaces in Next-generation Energy Conversion Materials

Prof. Schlenker will offer new insight into the molecular properties that determine charge carrier dynamics and suggests new strategies for materials design focused on kinetically suppressing recombination energy losses.

Model Based Battery Management System (BMS) for Electric Transportation and Renewable Microgrids

Proactive battery management systems (BMS) and advanced sensing technologies offer an opportunity to significantly reduce the cost and weight of transportation batteries, and circumvent problems arising due to capacity fade and safety concerns. This talk will describe how multiscale electrochemical engineering models, mathematical model reformulation and the use of robust algorithms can alleviate some of these problems to help electrify the transportation industry by improving the range of variables that are predictable and controllable in a battery in real-timewithin an electric vehicle. In addition, preliminary results on aggressive sizing and control strategies for batteries in renewable microgrids will be presented.

Interface Science of Organic Photovoltaics

In this lecture, challenges and opportunities in organic photovoltaic interface science are illustrated for four specific and interrelated areas of research: 1) controlling charge transport across hard matter(electrode)-soft matter interfaces in organic photovoltaic cells, 2) controlling charge transport by specific active layer orientational organization at electrodes, 3) controlling exciton dynamics and carrier generation at donor-acceptor interfaces in the active layer, 4) designing transparent conducting electrodes with improved properties.

Managing Variable Renewable Resources in the Smart Grid

This presentation will give an overview of the existing challenges to integrate variable renewable resources within the electric power grid.

Light Material Interactions for High Efficiency Solar Energy Conversion

In his lecture, Prof. Atwater discussed methods for systematically addressing the efficiency losses in current photovoltaics through micro- and nanoscale light management that can enable a next phase of photovoltaic science and engineering – ultrahigh efficiency photovoltaics.

The Ups and Downs of Umbrella Constraint Discovery in Electricity Generation

Recent work on umbrella constraint discovery (UCD) has shown great promise in streamlining the solution of security-constrained optimal power flow (SCOPF) problems. The solution of the UCD problem itself is not trivial, however. In this talk, we present a significant, yet simple, improvement to the decomposition approach used to solve UCD.

Perspectives on Our Energy Future

Providing clean energy to the inhabitants of our planet is a major challenge to future generations. This talk provided Prof. Dresselhaus’ perspectives on this challenge in general terms and on how nanoscience and new nano-materials may contribute to addressing this challenge.

Soft Generators that Harvest Energy From Renewable Sources

When stretched, a thin membrane of a dielectric elastomer expands its area and reduces its thickness. The deformation can increase the electric capacitance of the membrane over a thousand times.

Optimal Power Flow for Future Smart Grid

We envision a future network with hundreds of millions of active endpoints. These are not merely passive loads as are most endpoints today, but endpoints that may generate, sense, compute, communicate, and actuate.

Scaling Clean Energy Production -A Materials Grand Challenge

Dr. Cyrus Wadia will reflect on his experiences in government, academia and industry to articulate a new set of grand challenges toward the expansion of clean-energy and accelerated deployment of advanced materials.

The Clean Energy Institute recently invested more than $1 million in new instruments to support materials research and technology development.

The Washington Research Foundation will invest $6.74 million over six years that will support nine new faculty hires, six postdoctoral researchers and the creation of a new experimental manufacturing facility on campus that will help move discoveries from the laboratory to the marketplace. This investment in the CEI is truly transformational.”
