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.

The threat of climate change has profound implications for the evolution of the world’s energy system over the coming decades. More than many environmental problems, uncertainty is a central characteristic of the problem – uncertainty regarding the physical science of climate but also uncertainty regarding the impacts, technologies (for mitigation, adaptation and geoengineering), costs, and human preferences.
The problem is larger than simple uncertainty. Some uncertainty is objective and fits into a probabilistic paradigm; other uncertainty is much more vague, with unknown probabilities (such as the likelihood of inventing a cheap way of storing electricity by 2020). Furthermore, uncertainty changes over time, either simply by acquiring more experience or through proactive measures to increase knowledge (eg, R&D). And further, some uncertainty is managed automatically by individuals and organizations seeking to reduce risk exposure (eg, with flood insurance). The bottom line is how to manage the risks of climate change in this complex and evolving environment? Insurance, financial markets, individual action and public policy can and should work in tandem to deal with this uncertainty. This talk provides a perspective on managing risk associated with climate change.

Maxim Kelman and Jacob Woodruff are relatively recent Stanford graduates in physical science and engineering who have worked successfully in solar energy-related start-ups. Kelman and Woodruff will describe the evolution of their careers to date, lessons learned about the start-up world and how it differs from academic and larger corporate workplaces. This will include the implementation of research findings into pilot and manufacturing lines with accelerated development timelines, and what it is like to work in the early stages versus later stages after reorganization and introduction of new management. Personality traits that may be useful among start-up employees will also be discussed.

One third of the world's carbon emissions are emitted by industry. Most industrial emissions relate to producing materials. Steel, cement, plastic, paper and aluminium are the most important contributors. The industries that make materials are energy-intensive, so they have always been motivated to be efficient and have now reached a fantastic level of performance.
However, the world's demand for materials is growing, and likely to double by 2050. By default, industrial emissions will also double, unless we do something differently. This talk sets out an agenda for making a big difference to global emissions by requiring less new material. Based on a five-year project with eight researchers and a consortium of 20 large industrial partners, we have gathered evidence on six material efficiency options which allow us to provide the same final services (such as housing or transport) with significantly less material. The talk will present a series of case studies to demonstrate how these strategies can be applied in practice, and explore the actions by government, businesses and consumers that would bring them about.

Brian Hardin and Craig Peters (PlantPV) and Howard Turner (Kinestral) will discuss some of the important challenges that arise in founding a new energy technology company. Topics include both the tactical aspects of starting up a new venture, and more strategic considerations of entering an energy market with a technology developed using Silicon Valley venture capital funding. Speakers will explore key drivers, aside from interesting science, for selecting the technology space in which to start a company. They will also describe ways in which students may prepare themselves for future start-ups while still in school.

Grid flexibility is a characteristic that is proposed to help the integration of variable renewable energy resources. However it has proven very difficult to quantify and this has spurred intense research efforts over the past few years. There are many sources, sinks and enablers for flexibility in the grid and these are all subject to numerous research challenges. Flexibility will be introduced, defined and a number of methods to quantify it will be described. This will be followed by an overview of research into unlocking flexibility in the power system e.g. demand side participation and power system operational strategies. There are potential hidden costs of flexibility and some of these will be highlighted, for example thermal plant cycling, and mitigation measures to reduce these will be formulated. Concluding remarks will try to give insights into how a future grid with very high penetrations of variable renewable energy may look like.

Despite recent political attacks and negative headlines, the renewable energy and the solar industries emerge from 2012 ready to play a significant part in mainstream energy markets. Industry data reflects an increasing role for renewables as the fastest growing new source of electricity. It is now all but inevitable that our energy future will feature some combination of natural gas, wind, and solar. In this new era of mainstream clean energy, energy policy and industry action will determine what this future looks like. Will we end up with a gas-centric generating fleet with wind and solar around the edges? Or will we prioritize wind and solar with gas in a supporting role? What steps can we take to ensure renewables remain a central priority?

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.

Hydrogen Energy California is a project for converting fossil fuels to hydrogen in order to generate clean power and manufacture low-carbon fertilizer products. HECA will be one of the first industrial complexes combining a large, commercial scale power plant and a low-carbon footprint fertilizer manufacturing facility, while capturing the carbon dioxide (CO2) from the fossil fuel to hydrogen conversion process. Utilizing the CO2 for fertilizer production and enhanced oil recovery increases domestic energy security, while simultaneously storing the captured CO2 permanently in the geologic formations where the oil was extracted. It is a project that offers California, the nation, and the world progress toward controlling global climate change, while providing enormous economic stimulus through construction and related jobs over the intermediate term and permanent manufacturing and related jobs over the long term.
