Critical, imminent changes in the world energy portfolio have amplified pressure on development of advanced energy storage technology, for the grid, automotive and consumer electronics sectors. Technology advances are not only required to enable the largest entry of people to the middle classes in human history, but also to avert disastrous consequences of irrevocable climate change and environmental harm. Present Li-ion batteries (LiB), with a total addressable market of over $12B, expected to grow to over $23B in the next four years, cannot meet these burgeoning needs, for reasons of cost, performance and safety.
Present manufacturers of the incumbent technology all employ liquid electrolytes and lamination processing in highly conserved plant designs, producing cells that are not differentiated in cost, performance or safety. Additionally, lamination processing of LiBs has enormous built in costs, including up to two months’ of careful, pre-processing time for cells before they can be shipped to customers, comprising tremendous work-in-process (WIP) and additional, unremovable process cost and time. These formation and aging costs, coupled with limitations in construction due to lamination, physical limits of transport and mechanics and limited ability to integrate new materials into the existing manufacturing approach, will severely limit gains in performance and safety in this generation of technology. The incumbent technology further requires massive downstream costs to assure the safety of these liquid-based systems, in the form of safety and containment systems. Examination of a mapping of the available materials against their probable effect on cell properties yields a simple conclusion: the incumbent technology benefits have essentially reached their limit, as established holistically by laboratory developments, optimization simulations, and recent commercially reported properties.
Solid state battery technology, though offering a very different development path enabling breakthrough performance and safety, has been relegated to the realm of R&D due to intrinsically high cost, unscalable manufacturing processes that result in high cell cost. Recently, however, Sakti3, a University spinout founded by researchers and engineers with decades of experience in battery research and thin film and other manufacturing, developed an approach for production of cells which offers all of the benefits of the theoretically highest energy density materials available. These massively replicable, cheap and reliable production methods enable cell manufacturing in a single, unified line and produce product that is ready to ship.
Integration of new, environmentally benign energy generation technologies will require improved energy storage both for regulation of load, and for storage of solar and wind power. Non emissive automobiles and use of existing electrical power grids to power them, require safe, onboard traction storage systems. And finally, the democratization of information and the use of mobile devices as the primary, and often the only, connectivity to the internet and commerce, requires safe, high energy density storage technology be available to the consumer. We discuss our vision for technology deployment and future product development using solid state processing of energy storage technology and integration into existing and new infrastructures.
Commercializing Wind, Photovoltaics, Lighting, and Batteries: The Impact of Government Policies During the Past 25 Years

On March 10th, Cathy Zoi will present the findings from Energy 158, a research seminar held during the Fall of 2013, that investigated the progress of wind, photovoltaics, lighting and batteries over the past 30 years, and the impact that government intervention had on this progress. She will then apply these lessons from history to propose a framework policy makers can use in the future.
Rationale for the research: Public policy imperatives have created a drive for energy technologies that can reduce greenhouse gas emissions, improve national security, and boost domestic economic activity. To accelerate the development and commercialization of these new technologies beyond what the market would deliver on its own, governments frequently use policies like direct R&D funding, financial incentives or penalties (e.g. through the tax code, state funds, or utility rates), mandatory targets or caps, information disclosure, and performance codes and standards to create market conditions that favor emerging technologies. There is significant public debate about the most effective mix of these policy interventions.

In the past two decades rechargeable batteries have been a great success in powering consumer electronics. There is a recent strong interest in applying rechargeable batteries to vehicle electrification and grid-scale storage, which present new challenges and opportunities for batteries including energy density, cost, safety, cycle life among many parameters. This talk reviews existing technologies and looks into next generation of batteries with great promise for vehicles and grids. Particularly, novel battery materials are key for a revolutionary change. High-energy batteries examples include silicon and lithium metal anodes, and sulfur and air cathodes. Novel aqueous and redox-flow batteries with low cost could impact the grid-scale storage. Smart separators could enhance the battery safety significantly.

The Renewable Electricity Futures Study is an initial investigation of the extent to which renewable energy supply can meet the electricity demands of the contiguous United States over the next several decades. This study explores the implications and challenges of very high renewable electricity generation levels--from 30% up to 90%, focusing on 80%, of all U.S. electricity generation from renewable technologies--in 2050.
At such high levels of renewable electricity penetration, the unique characteristics of some renewable resources, specifically geographical distribution and variability and uncertainty in output, pose challenges to the operability of the nation's electric system. The study focuses on key technical implications of this environment from a national perspective, exploring whether the U.S. power system can supply electricity to meet customer demand on an hourly basis with high levels of renewable electricity, including variable wind and solar generation. The study also identifies some of the potential economic, environmental, and social implications of deploying and integrating high levels of renewable electricity in the United States.

What happens when you put lots of wind and solar power onto the power system? Do you need more storage? Do you need more reserves? When does the system 'break'? What actions can be taken to integrate wind and solar power into the power system without large cost increases to consumers?
Wind and solar power are inherently variable and uncertain. This causes difficulties for power system operators who must maintain reliability. Over the past several years, utilities and researchers have simulated power system operation with various penetration levels of renewable energy, examining increased costs due to integration of the renewables and mitigation measures to more cost-effectively accommodating the renewables. Debbie will present an overview of recent renewable energy integration studies in the US and Europe. She will focus on the recently released Western Wind and Solar Integration Study, one of the largest wind and solar integration studies to date, that examines the integration of up to 35% wind and solar energy into the power system. Issues addressed include: utility cooperation, tradeoffs between local and remote renewable energy resources, geographic diversity, storage, reserves, and improved forecasting.

In the last two years, the world has seen an unprecedented momentum toward electric vehicles. Leadership by governments committed to electrification, together with the right economics and policy, is catalyzing a race in the global automotive industry toward electrification. While primary motivations for countries leading on electrification differ form oil dependence to developing globally dominant automotive industries to zero-emission transportation and integration of renewable generation, the answer is the same. Electrification enables all of these benefits, if it is done at scale. Yet even as China, Europe and other markets surge forward with electric vehicles, the US lags behind. This session will explore the global momentum for electrification, the barriers and opportunities to mass adoption of electric vehicles, and the lessons for the US on the economics and policy of EV’s.

Solar energy is an attractive option that could potentially provide our energy needs in sustainable fashion, but a number of major scientific challenges stand in the way of developing cost-effective methods to capture and store solar energy at the terrestrial scale. One means to store this energy is in the form of fuels, i.e. using solar energy to drive redox reactions such as splitting water into H2 and O2 or the conversion of atmospheric CO2 to alcohols and hydrocarbons. This talk will focus on the development of the three key components needed to synthesize liquid and gaseous fuels from sunlight: (1) semiconductors with appropriate electronic band structure for solar photon absorption and for sufficient photovoltage to drive redox reactions, (2) water oxidation catalysis to provide the protons and electrons needed for the fuel synthesis reduction reactions, and (3) electro-reduction catalysis for the evolution of hydrogen and/or the reduction of CO2 to liquid fuels. The exploitation of nano-scale effects will be discussed as a means to tailor material surface and bulk properties to fit these needs.

Consumer Response to Plug-in Electric Vehicles
We are in historic times for the auto industry, along many dimensions, from the expanding of car ownership in developing nations, to the peaking of oil, and to the challenges of climate change. In the past, automobile products have changed slowly compared to other “tech” markets. Today, most automobiles are in many basic ways much like vehicles of the past few decades. A few clean and efficient vehicles are having successes in the market and bigger technological changes seem to loom ahead; in particular, in the next few years, automobile makers will attempt to commercialize electric and plug-in hybrid vehicles around the world. Are these products that only a few engineers, enthusiasts and devoted environmentalists want or are these products that will transform the auto industry, embraced by the wide consumer market? For 20 years, researchers at UC Davis have been probing this question, surveying and interviewing car owners about their fuel use, actual or potential use of green cars, alternative fuels, want for small urban or neighborhood cars and electric drive vehicles in particular. UCD researchers have studied consumer response to the basic practical issues, such as purchase costs, operating costs, the constraints of vehicle range, the use of charging stations as well as more cultural arenas such as the development of new symbols, values, the role of information in car owner’s social networks, environmental concepts, efficient driving practices, and the use of energy feedback instruments. Dr. Turrentine reviews the relevant lessons he and his research team at UC Davis have learned in the past 20 years about the electrification of transportation and shares recent findings from his work with BMW in the MINI E program and from the 70 Northern California Automobile Association households who have participated in the PH&EV center PRIUS PHEV conversion program.
