Review of energy system flexibility measures to enable high levels of variable renewable electricity

The paper reviews different approaches, technologies, and strategies to manage large-scale schemes of variable renewable electricity such as solar and wind power. We consider both supply and demand side measures. In addition to presenting energy system flexibility measures, their importance to renewable electricity is discussed. The flexibility measures available range from traditional ones such as grid extension or pumped hydro storage to more advanced strategies such as demand side management and demand side linked approaches, e.g. the use of electric vehicles for storing excess electricity, but also providing grid support services. Advanced batteries may offer new solutions in the future, though the high costs associated with batteries may restrict their use to smaller scale applications. Different “P2Y”- type of strategies, where P stands for surplus renewable power and Y for the energy form or energy service to which this excess in converted to, e.g. thermal energy, hydrogen, gas or mobility are receiving much attention as potential flexibility solutions, making use of the energy system as a whole. To “functionalize” or to assess the value of the various energy system flexibility measures, these need often be put into an electricity/energy market or utility service context. Summarizing, the outlook for managing large amounts of RE power in terms of options available seems to be promising.

The Joint Center for Energy Storage Research: A New Paradigm for Battery Research and Development

The Joint Center for Energy Storage Research (JCESR) seeks transformational change in transportation and the electricity grid driven by next generation high performance, low cost electricity storage. To pursue this transformative vision JCESR introduces a new paradigm for battery research: integrating discovery science, battery design, research prototyping and manufacturing collaboration in a single highly interactive organization. This new paradigm will accelerate the pace of discovery and innovation and reduce the time from conceptualization to commercialization. JCESR applies its new paradigm exclusively to beyond-lithium-ion batteries, a vast, rich and largely unexplored frontier. This review presents JCESR’s motivation, vision, mission, intended outcomes or legacies and first year accomplishments.

US Energy Storage Market to grow 250% in 2015

The U.S. energy storage market grew 40% in 2014, installing 61.9 MW. GTM Research forecasts 220 MW of energy storage installations in 2015. By 2019, the U.S. will be an 861 MW annual market, valued at $1.5 billion

This report is directed towards those developing, marketing and using small electronic and
electrical devices, particularly those that are self-sufficient. There is therefore much to interest those with a technical background as well. The report looks hard at what comes next, particularly over the next ten years. 
Citi GPS Report: Investment Themes in 2015, Dealing with Divergence

Citi GPS is pleased to present our investment themes for 2015 and well wishes to all readers of the Citi GPS series successful investing in the year ahead. As in 2014, these themes are a mixture of macro and asset class views together with several ideas selected from our global industry analysis. At the end of each year we conduct a survey to ask users of Citi Research which themes they would like to see us tackle in the year ahead1. We have used the intelligence of this survey to scope this annual Citi GPS Investment Themes report.

Managing End-of-Life Lithium-ion Batteries: an Environmental and Economic Assessment

The growing market for lithium-ion batteries raises concerns about sustainable management of those batteries at end of life. Launching relevant policies requires a comprehensive understanding of potential economic values as well as environmental performance of end-of-life lithium-ion batteries. However, both recyclers and policymakers are facing a number of unanswered questions, including 1) how battery technology trajectory would affect the incentives for recycling? 2) what strategies are available to improve material recovery efficiency? and 3) what is the potential for nanoparticle release during end-of-life processing, particularly for next-generation lithium-ion batteries who contain nano-scale cathode materials? This dissertation aims to fill these research gaps. Multi-criteria optimization modeling and fundamental material characterization methods were used to quantify environmental and economic trade-offs for end-of-life lithium-ion batteries.

Global Energy Storage Demand for a 100% Renewable Electricity Supply

This study demonstrates – based on a dynamical simulation of a global, decentralized 100% renewable electricity supply scenario – that a global climate-neutral electricity supply based on the volatile energy sources photovoltaics (PV), wind energy (onshore) and concentrated solar power (CSP) is feasible at decent cost. A central ingredient of this study is a sophisticated model for the hourly electric load demand in >160 countries. To guarantee matching of load demand in each hour, the volatile primary energy sources are complemented by three electricity storage options: batteries, high-temperature thermal energy storage coupled with steam turbine, and renewable power methane (generated via the Power to Gas process) which is reconverted to electricity in gas turbines. The study determines – on a global grid with 1°x1° resolution – the required power plant and storage capacities as well as the hourly dispatch for a 100% renewable electricity supply under the constraint of minimized total system cost (LCOE). Aggregating the results on a national level results in an levelized cost of electricity (LCOE) range of 80-200 EUR/MWh (on a projected cost basis for the year 2020) in this very decentralized approach. As a global average, 142 EUR/MWh are found. Due to the restricted number of technologies considered here, this represents an upper limit for the electricity cost in a fully renewable electricity supply

Powering a Brighter Tomorrow SUSTAINABILITY REPORT 2011 - 2013

With our 2011-2013 Sustainability Report, we are excited to announce progress in advancing our triple bottom line – economic, environmental and social performance. The information presented in this report spans fiscal years 2011, 2012 and 2013, up to and including Dec. 29, 2013, unless otherwise stated. It covers all wholly owned SunPower operations as well as joint ventures but excludes contract manufacturing as well as engineering, procurement and construction (EPC) activities. The majority of our environmental performance information includes data gathered from our key facilities that represent the majority of our environmental impacts and house our manufacturing, research and development, assembly and headquarters operations. We have not sought third-party verification of this report but we have practices in place to internally validate this data. We provide a detailed accounting of our risks and opportunities related to climate change in our 2012 and 2013 Carbon Disclosure Project (CDP) Submissions
