Storage

Agile Delivery of Electrical Power Technology

In today's increasingly electrified world, power conversion--the process of converting electricity between different currents, voltage levels, and frequencies--forms a vital link between the electronic devices we use every day and the sources of power required to run them. The projects that make up ARPA-E's ADEPT program, short for "Agile Delivery of Electrical Power Technology," are paving the way for more energy efficient power conversion and advancing the basic building blocks of power conversion: circuits, transistors, inductors, transformers, and capacitors.

Advanced Management and Protection of Energy Storage Devices

The projects that comprise ARPA-E's AMPED Program, short for "Advanced Management and Protection of Energy Storage Devices," seek to develop advanced sensing, control, and power management technologies that redefine the way we think about battery management. Energy storage can significantly improve U.S. energy independence, efficiency, and security by enabling a new generation of electric vehicles. While rapid progress is being made in new battery materials and storage technologies, few innovations have emerged in the management of advanced battery systems. AMPED aims to unlock enormous untapped potential in the performance, safety, and lifetime of today's commercial battery systems exclusively through system-level innovations, and is thus distinct from existing efforts to enhance underlying battery materials and architectures.

Cycling Hardware to Analyze and Ready Grid-Scale Electricity Storage

Methods for storing electricity for the electric power system (i.e. the grid) are developing rapidly, but widespread adoption of these technologies requires real-world data about their performance, economic benefit, and long-term reliability. The CHARGES program, short for "Cycling Hardware to Analyze and Ready Grid-Scale Electricity Storage," establishes two sites where ARPA-E-funded battery technologies will be tested under conditions designed to represent not just today's applications, but also the demands of tomorrow's electric power system. The program will establish realistic duty cycles for storage devices on a microgrid, and test them in both a controlled environment and under realistic microgrid operating conditions. The objective of the CHARGES program is to accelerate the commercialization of electrochemical energy storage systems developed in current and past ARPA-E-funded research efforts. The program aims to help ARPA-E-funded battery development teams improve their storage technologies to deliver substantial economic benefit under real-world conditions, both now and in the future.

Duration Addition to electricitY Storage

The projects that comprise ARPA-E's DAYS (Duration Addition to electricitY Storage) program will develop energy storage systems that provide power to the electric grid for durations of 10 to approximately 100 hours, opening significant new opportunities to increase grid resilience and performance. Whereas most new energy storage systems today deliver power over limited durations, for example to alleviate transmission congestion, stabilize voltage and frequency levels, or provide intra-day shifts of energy, the extended discharge times of DAYS projects will enable a new set of applications including long-lasting backup power and even greater integration of domestic, renewable energy resources.Project teams will seek to develop storage systems that are deployable in almost any location and charge and discharge electricity at a target fixed cost per cycle. Projects will fall into two categories: 1) DAYS systems that provide daily cycling in addition to longer duration, less frequent cycling and 2) DAYS systems that do not provide daily cycling, but can take over when daily cycling resources are either filled or depleted. DAYS projects will explore a new design space in electricity storage that allows for strategic compromise of performance to achieve extremely low costs. The program also seeks to establish new paradigms for increasing stored energy and extending duration of stationary electricity storage systems.

Grid-Scale Rampable Intermittent Dispatchable Storage

The projects that comprise ARPA-E's GRIDS program, short for "Grid-Scale Rampable Intermittent Dispatchable Storage," are developing storage technologies that can store renewable energy for use at any location on the grid at an investment cost less than $100 per kilowatt hour. Flexible, large-scale storage would create a stronger and more robust electric grid by enabling renewables to contribute to reliable power generation.

High Energy Advanced Thermal Storage

The projects that make up ARPA-E's HEATS program, short for "High Energy Advanced Thermal Storage," seek to develop revolutionary, cost-effective ways to store thermal energy. HEATS focuses on 3 specific areas: 1) developing high-temperature solar thermal energy storage capable of cost-effectively delivering electricity around the clock and thermal energy storage for nuclear power plants capable of cost-effectively meeting peak demand, 2) creating synthetic fuel efficiently from sunlight by converting sunlight into heat, and 3) using thermal energy storage to improve the driving range of electric vehicles (EVs) and also enable thermal management of internal combustion engine vehicles.

Innovative Development in Energy-Related Applied Science

The IDEAS program - short for Innovative Development in Energy-Related Applied Science - provides a continuing opportunity for the rapid support of early-stage applied research to explore pioneering new concepts with the potential for transformational and disruptive changes in energy technology. IDEAS awards, which are restricted to maximums of one year in duration and $500,000 in funding, are intended to be flexible and may take the form of analyses or exploratory research that provides the agency with information useful for the subsequent development of focused technology programs. IDEAS awards may also support proof-of-concept research to develop a unique technology concept, either in an area not currently supported by the agency or as a potential enhancement to an ongoing focused technology program. This program identifies potentially disruptive concepts in energy-related technologies that challenge the status quo and represent a leap beyond today's technology. That said, an innovative concept alone is not enough. IDEAS projects must also represent a fundamentally new paradigm in energy technology and have the potential to significantly impact ARPA-E's mission areas.

Integration and Optimization of Novel Ion-Conducting Solids

Today's growing demand for electricity from carbon-free, renewable resources and for alternatives to petroleum as a transportation fuel has led to a strong desire for cost-effective and durable energy storage and conversion products. The projects that make up ARPA-E's IONICS program, short for "Integration and Optimization of Novel Ion-Conducting Solids," are paving the way for technologies that overcome the limitations of current battery and fuel cell products by creating high performance separators and electrodes built with solid ion conductors. The program will focus on developing new processing methods and approaches to device integration to accelerate devices built with high performance ion-conducting solids to commercial deployment.

Reliable Electricity Based on ELectrochemical Systems

Fuel cell technologies have been touted for decades due to their high chemical-to-electrical conversion efficiencies and potential for near-zero greenhouse gas emissions. Fuel cell technologies for power generation have not achieved widespread adoption, however, due primarily to their high cost relative to more established combustion technologies. There is a critical need to develop fuel cell technologies that can enable distributed power generation at low cost and high performance. The projects that comprise ARPA-E's Reliable Electricity Based on ELectrochemical Systems (REBELS) program include transformational fuel cell devices that operate in an intermediate temperature range in an attempt to create new pathways to achieve an installed cost to the end-user of less than $1,500/kW at moderate production volumes and create new fuel cell functionality that will help increase grid stability and integration of renewable energy technologies such as wind and solar.

24M Technologies

Large-Area Lithium Electrode Sub-Assemblies (LESAs) Protected by Self-Forming Microstructured Polymer-Inorganic Single-Ion Conducting Composites

24M Technologies will lead a team to develop low cost, durable, enhanced separators/solid state electrolytes to build batteries using a lithium metal anode. Using a polymer/solid electrolyte ceramic blend, 24M will be able to make a protective layer that will help eliminate side reactions that have previously contributed to performance degradation and provide a robust mechanical barrier to branchlike metal fibers called dendrites. Unimpeded, dendrites can grow to span the space between the negative and positive electrodes, causing a short-circuit. The resulting, large-area lithium electrode sub-assemblies, or LESAs, will be cost-effective solutions that are scalable to high-volume manufacturing while providing a toolbox to further tailor electrode performance.

3M

Low Cost, Durable Anion Exchange Membranes

3M will develop a new anion exchange membrane (AEM) technology with widespread applications in fuel cells, electrolyzers, and flow batteries. Unlike many proton exchange membrane (PEM) applications, the team's AEM will operate in an alkaline environment, which means lower-cost electrodes can be used. The team plans to engineer a membrane that simultaneously meets key goals for resistance, mechanical and chemical stability, and cost. They will do this by focusing on simple, hydroxide-stable polymers, such as polyethylene, and stable cations, such as tetraalkylammonium and imidazolium groups. Positively-charged cation side chains attached to the polymer backbone will facilitate passage of hydroxide ions through the electrolyte, resulting in enhanced ionic conductivity. The proposed polymer chemistry is envisioned to be low cost and can be used in alkaline environments, and can be processed into mechanically robust membrane composites. This membrane technology has the potential to enable high volume, low-cost production of AEMs. The impact of this project can be transformational as the commercial availability of high-quality AEMs has been a limiting factor in developing AEM-based devices.

ABB, Inc.

Superconducting Magnet Energy Storage System with Direct Power Electronics Interface

ABB is developing an advanced energy storage system using superconducting magnets that could store significantly more energy than today's best magnetic storage technologies at a fraction of the cost. This system could provide enough storage capacity to encourage more widespread use of renewable power like wind and solar. Superconducting magnetic energy storage systems have been in development for almost 3 decades; however, past devices were designed to supply power only for short durations--generally less than a few minutes. ABB's system would deliver the stored energy at very low cost, making it ideal for eventual use in the electricity grid as a cost-effective competitor to batteries and other energy storage technologies. The device could potentially cost even less, on a per kilowatt basis, than traditional lead-acid batteries.

Abengoa Solar, LLC

High-Efficiency Solar-Electric Conversion Power Tower

Abengoa Solar is developing a high-efficiency solar-electric conversion tower to enable low-cost, fully dispatchable solar energy generation. Abengoa's conversion tower utilizes new system architecture and a two-phase thermal energy storage media with an efficient supercritical carbon dioxide (CO2) power cycle. The company is using a high-temperature heat-transfer fluid with a phase change in between its hot and cold operating temperature. The fluid serves as a heat storage material and is cheaper and more efficient than conventional heat-storage materials, like molten salt. It also allows the use of a high heat flux solar receiver, advanced high thermal energy density storage, and more efficient power cycles.

Alveo Energy

Open Framework Electrode Batteries for Cost-Effective Stationary Storage

Alveo Energy is developing a grid-scale storage battery using Prussian Blue dye as the active material within the battery. Prussian Blue is most commonly known for its application in blueprint documents, but it can also hold electric charge. Though it provides only modest energy density, Prussian Blue is so readily available and inexpensive that it could provide a cost-effective and sustainable storage solution for years to come. Alveo will repurpose this inexpensive dye for a new battery that is far cheaper and less sensitive to temperature, air, and other external factors than comparable systems. This will help to facilitate the adoption and deployment of renewable energy technology. Alveo's Prussian Blue dye-based grid-scale storage batteries would be safe and reliable, have long operational lifetime, and be cheaper to produce than any existing battery technology.

American Manufacturing, Inc.

Flash Sintering System for Manufacturing Ion-Conducting Solids

American Manufacturing, in collaboration with the University of Colorado at Boulder, will develop a flash sintering system to manufacture solid lithium-conducting electrolytes with high ionic conductivity. Conventional sintering is the process of compacting and forming a solid mass by heat and/or pressure without melting it to the point of changing it to a liquid, similar to pressing a snowball together from loose snow. In conventional sintering a friable ceramic "bisque" is heated for several hours at very high temperatures until it becomes dense and strong. Oxide ceramics for solid-state electrolytes have high melting points, and some are chemically stable and do not react with lithium metal, which can reduce cost and maximize energy density. But the sintering process requires several hours at very high temperatures (1100°C). These conditions conflict with the fast movement of lithium atoms in the solid state, which is a key property of the electrolyte. Therefore, the manufacture of these electrolytes by the conventional sintering process is a key barrier to their cost and viability. In contrast, flash sintering can occur in fewer than 5 seconds, at temperatures below 800°C, and can prevent the loss of lithium experienced in conventional sintering. This project is expected to improve lithium battery technology in the following ways: lowering the cost of sintering and processing; enhancing productivity through roll-to-roll manufacturing of co-sintered multilayers ready to be inserted into devices; and hastening the discovery of new materials by shortening the time between synthesis of new chemistries and their electrochemical evaluation to days instead of months.

Antora Energy

Solid State Thermal Battery

The Antora Energy team will develop key components for a thermal energy storage system (solid state thermal battery) that stores thermal energy in inexpensive carbon blocks. To charge the battery, power from the grid will heat the blocks to temperatures exceeding 2000°C (3632°F) via resistive heating. To discharge energy, the hot blocks are exposed to thermophotovoltaics (TPV) panels that are similar to traditional solar panels but specifically designed to efficiently use the heat radiated by the blocks. The team will develop a thermophotovoltaic heat engine capable of efficiently and durably converting high-temperature heat into electricity. It will seek to double panel efficiency through new materials and smart system design, potentially enabling a cost effective grid storage solution.
