Currently Funded Projects


Partnering Institution(s): Laboratory for Laser Energetics at the University of Rochester; Lawrence Livermore National Laboratory

Project Summary: Sandia National Laboratories will partner with the Laboratory for Laser Energetics at the University of Rochester to investigate the behavior of the magnetized plasma under fusion conditions, using a fusion concept known as Magnetized Liner Inertial Fusion (MagLIF). MagLIF uses lasers to pre-heat a magnetically insulated plasma in a metal liner and then compresses the liner to achieve fusion. The research team will conduct experiments at Sandia’s large Z facility as well as Rochester’s OMEGA facilities, and will collect key measurements of magnetized plasma fuel including temperature, density, and magnetic field over time.

Transformational Merit: The results will help researchers improve compression and heating performance. By using the smaller OMEGA facility, researchers will be able to conduct experiments more rapidly, speeding the learning process and validating the MagLIF approach. Sandia’s team will also use their experimental results to validate and expand a suite of simulation and numerical design tools to improve future fusion energy applications that employ magnetized inertial fusion concepts. This project will help accelerate the development of the MagLIF concept, and assist with the continued development of intermediate density approaches across the ALPHA program.



 Partnering Institution(s): University of New Mexico

Project Summary: Vertical transistors based on bulk gallium nitride (GaN) have emerged as promising candidates for future high efficiency, high power applications. However, they have been plagued by poor electrical performance attributed to the existing selective doping processes. Sandia National Laboratories will develop patterned epitaxial regrowth of GaN as a selective area doping processes to fabricate diodes with electronic performance equivalent to as-grown state-of-the-art GaN diodes.

Transformational Merit: The team’s research will provide a better understanding of which particular defects resulting from impurities and etch damage during the epitaxial regrowth process limit device performance, how those defects specifically impact the junction electronic properties, and ultimately how to control and mitigate the defects. The improved mechanistic understanding developed under the project will help the team design specific approaches to controlling impurity contamination and defect incorporation at regrowth interfaces and include development of in-chamber cleans and regrowth initiation processes to recover a high-quality epitaxial surfaces immediately prior to crystal regrowth.

Partnering Institution(s):


Project Summary: Sandia National Laboratories will develop a new type of switch, a 100kV optically controlled switch (often called photoconductive semiconductor switch or PCSS), based on the WBG semiconductors GaN and AlGaN. The capabilities of the PCSS will be demonstrated in high-voltage circuits for medium and high voltage direct current (MVDC/HVDC) power conversion for grid applications. Photoconductivity is the measure of a material’s response to the energy inherent in light radiation. The electrical conductivity of a photoconductive material increases when it absorbs light. The team will first measure the photoconductive properties of GaN and AlGaN in order to assess if they operate similarly to gallium arsenide, a conventional semiconductor material used for PCSS, demonstrating sub-bandgap optical triggering and low-field, high-gain avalanche providing many times as many carriers by the electric field as created by the optical trigger. These two effects provide a tremendous reduction in the optical trigger energy required to activate the switch. The team will then design and fabricate GaN and AlGaN-based photoconductive semiconductor switches.

Transformational Merit: The team predicts that WBG PCSS will outperform their predecessors with higher switch efficiency, the ability to switch at higher voltages, and will turn-off and recover faster, allowing for a higher frequency of switching. Ultimately, this will enable high-voltage switch assemblies (50-500kV) that can be triggered from a single, small driver (e.g. semiconductor laser). These modules will be substantially smaller (~10x) and simpler than existing modules used in grid-connected power electronics, allowing the realization of inexpensive and efficient switch modules that can be used in DC to AC power conversion systems on the grid at distribution and transmission scales.

Partnering Institution(s): University of New Mexico


Project Summary: Sandia National Laboratory will develop novel, field-deployable sensor technologies for monitoring soil, root, and plant systems. First, the team will develop microneedles similar and shape and function to hypodermic needles used in transdermal drug delivery and wearable sensors. The minimally invasive needles will be used to report on sugar concentrations and water stress in leaves, stems, and large roots in real-time. Continuously monitoring the sugar concentrations at multiple locations will be transformative in understanding whole plant carbon dynamics and the function of the vascular tissues that conduct sugars and other metabolic products downward from the leaves. The second key technology are gas chromatographs deployed in the soil and near plants in order to monitor volatile organic compounds (VOC). Plants synthesize and release volatile organic compounds both aboveground and belowground that act as chemical signals or in response to biotic stress (damage from insects, bacteria, etc.) or abiotic stress (such as drought, flooding, and extreme temperatures). VOCs modulate biomass uptake and the team hopes to better understand soil composition by measuring VOC transport.

Transformational Merit: The team’s integrated microsensor technologies will be deployed in arid environments in both natural and agricultural lands to characterize whole plant function in both environments. Applying these sensors to plants in arid environments could assist in re-greening arid ecosystems with new specially bred plants developed and selected to improve soil function with less water and nutrient requirements while depositing more soil carbon.

Partnering Institutions: Harvard University (Lead)


Project Summary: Harvard University in partnership with Sandia National Laboratories will develop a transistor-less 16kW DC to DC converter boosting a 0.5kV DC input to 8kV that is scalable to 100kW. If successful, the transistor-less DC to DC converter could improve the performance of power electronics for electric vehicles, commercial power supplies, renewable energy systems, grid operations, and other applications. Converting DC to DC is a two-step process that traditionally uses fast-switching transistors to convert a DC input to an AC signal before the signal is rectified to a DC output. The Harvard and Sandia team will improve the process by replacing the active, fast-switching transistors with a slow switch followed by a passive, nonlinear transmission line (NLTL). The NLTL is a ladder network of passive components (inductors and diodes) that provide a nonlinear output with voltage. The combination of the nonlinear behavior with dispersion converts a quasi-DC input into a series of sharper and taller (amplified) voltage pulses called solitons, thus executing the DC to AC conversion without the use of active, fast-switching transistors. The NLTL will be followed by a high breakdown voltage silicon carbide and/or gallium nitride diode-based accumulator that converts the series of solitons to a DC output. Replacing the fast-switching transistors with a slow switch and a NLTL addresses the cost, size, efficiency, and reliability issues associated with fast switching based converters. Diodes also cost less and last longer because they are simpler structures than transistors and use no dielectrics.

Transformational Merit: Efficiency, cost, and reliability improvements provided by a NLTL-based power converter will drastically benefit commercial power supplies, industrial motors, electric vehicles, data centers, the electric grid, and renewable electric power generation such as solar and wind.

Partnering Institution(s): iBeam Materials (Lead), Los Alamos National Laboratory


Project Summary:iBeam Materials is developing a scalable manufacturing method to produce low-cost gallium nitride (GaN) LED devices for use in solid-state lighting. iBeam Materials uses an ion-beam crystal-aligning process to create single-crystal-like templates on arbitrary substrates thereby eliminating the need for small rigid single-crystal substrates.

Transformational Merit:This process is inexpensive, high-output, and allows for large-area deposition in particular on flexible metal foils. In using flexible substrates, in contrast to rigid single-crystal wafers, the ion-aligning process also enables roll-to-roll (R2R) processing of crystalline films. R2R processing in turn simplifies manufacturing scale-up by reducing equipment footprint and associated labor costs By fabricating the LED directly on a metal substrate, one “pre-packages” the LED with the reflector and the heat sink built-in. This significantly reduces cost, simplifies packaging and allows a pick-and-place (P&P) technology to be replaced with printing of LEDs.

Partnering Institution(s): IR Dynamics (Lead); Madico Inc.


Project Summary: IR Dynamics, LLC will develop a low-cost nanomaterial technology to be incorporated into flexible window films that will improve thermal insulation and solar heat gain. The team’s nanomaterial will incorporate two materials. First, low-cost nanosheets will increase thermal resistance. Second, a new type of nanomaterial will allow heat, in the form of infrared radiation (IR) from the sun, to pass through the window when it is cold outside, helping to warm the room in cold weather. When it is hot outside, the material will block the solar IR from passing through the window and warming the interior. This same material reflects thermal radiation and displays a tunable emissivity, contributing more to its insulation value and energy retention. The dynamic IR reflectivity and emissivity are passive by nature, requiring no electronics or power source to shift, and only rely on environmental temperature changes.

Transformational Merit: IR Dynamics’ technology creates a window film that automatically adjusts depending on outside temperatures and can have a substantive impact in performance on single-pane and older variants of double-pane windows.

Partnering Institution(s): Massachusetts Institute of Technology (MIT)


Project Summary: The Massachusetts Institute of Technology (MIT) with partner Sandia National Laboratories will develop a micro-CPV system. The team’s approach integrates optical concentrating elements with micro-scale solar cells to enhance efficiency, reduce material and fabrication costs, and significantly reduce system size. The team’s key innovation is the use of traditional silicon PV cells for more than one function. These traditional cells lay on a silicon substrate that has etched reflective cavities with high-performance micro-PV cells on the cavity floor. Light entering the system will hit a primary concentrator that then directs light into the reflective cavities and towards the high performance micro-PV cells.

Transformational Merit: Diffuse light, which most CPV technologies do not capture, is collected by the lower performance silicon PV cells. The proposed technology could provide 40-55% more energy than conventional FPV and 15-40% more energy than traditional CPV with a significantly reduced system cost, because of the ability to collect both direct and diffuse light in a thin form factor.

Partnering Institution(s): Palo Alto Research Center (PARC) (Lead)


Project Summary: The Palo Alto Research Center (PARC), a Xerox company, along with Sandia National Laboratories (SNL) will develop a prototype printer with the potential to enable economical, high-volume manufacturing of micro-PV cell arrays. This project will focus on creating a printing technology that can affordably manufacture micro-CPV system components. The envisioned printer would drastically lower assembly costs and increase manufacturing efficiency of micro-CPV systems. Leveraging their expertise in digital copier assembly, PARC intends to create a printer demonstration that uses micro-CPV cells or “chiplets” as the “ink” and arranges the chiplets in a precise, predefined location and orientation, similar to how a document printer places ink on a page. SNL will provide micro-scaled photovoltaic components to be used as the “ink,” and the PARC system will “print” panel-sized micro-CPV substrates with digitally placed and interconnected PV cells.

Transformational Merit: This micro-chiplet printer technology may reduce the assembly cost of micro-CPV systems by orders of magnitude, making them cost competitive with conventional FPV. To demonstrate the effectiveness of the printer, the project team will investigate two types of backplanes (electronically connected PV arrays arranged on a surface): one with a single type of micro-PV cell, and one with at least two types of micro-PV cells.

ARPA-E Program: Open Funding Opportunity Announcement

Project Summary: The team led by the University of Virginia will design the world’s largest wind turbine by employing a new downwind turbine concept called Segmented Ultralight Morphing Rotor (SUMR). Increasing the size of wind turbine blades will enable a large increase in power from today’s largest turbines – from an average of 5-10MW to a proposed 50MW system. The SUMR concept allows blades to deflect in the wind, much like a palm tree, to accommodate a wide range of wind speeds (up to hurricane-wind speeds) with reduced blade load, thus reducing rotor mass and fatigue. The novel blades also use segmentation to reduce production, transportation, and installation costs.

Transformational Merit: This innovative design overcomes key challenges for extreme-scale turbines resulting in a cost-effective approach to advance the domestic wind energy market. The team includes world’s experts at the National Renewable Energy Laboratory (NREL) and Sandia National Labs (SNL) working with world-class faculty and students at the Colorado School of Mines, University of Colorado (Boulder), University of Illinois (Urbana-Champaign), and the University of Virginia.

Partnering Institution(s): University of Maryland (UMD) (Lead), Oak Ridge National Laboratory


Project Summary: Heating, Ventilation, and Air Conditioning (HVAC) account for 13% of energy consumed in the U.S. and about 40% of the energy used in a typical U.S. residence, making it the largest energy expense for most homes. Even though more energy-efficient HVAC technologies are being adopted in both the commercial and residential sectors, these technologies focus on efficiently heating or cooling large areas and dealing with how the building’s net occupancy changes during a day, a week and across seasons. Building operators have to tightly manage temperature for an average occupancy comfort level; but the occupants only occupy a small fraction of the building’s interior.

Transformational Merit:There is a critical need for technologies that create localization of thermal management to relax the temperature settings in buildings, reduce the load on HVAC systems and enhance occupant comfort. This is achieved by tailoring the thermal environment around the individual, thus saving energy by not over-heating or over-cooling areas within the building where the occupants do not reside.

Partnering Institution(s): Arizona State University (Lead); Nexant, Inc.; PJM Interconnection


Project Summary: Arizona State University (ASU) will develop a stochastic optimal power flow (SOPF) framework, which would integrate uncertainty from renewable resources, load, distributed storage, and demand response technologies into bulk power system management in a holistic manner. The team will develop SOPF algorithms for the security-constrained economic dispatch (SCED) problem used to manage variability in the electric grid. The algorithms will be implemented in a software tool to provide system operators with real-time guidance to help coordinate between bulk generation and large numbers of DERs and demand response. ASU’s project features unique data-analytics based short-term forecast for bulk and distributed wind and solar generation utilized by the advisory tool that generates real-time recommendations for market operators based on the SOPF algorithm outputs.

Transformational Merit: If successful, projects included in the NODES Program will develop innovative hardware and software solutions to integrate and coordinate generation, transmission, and end-use energy systems at various points on the electric grid. These control systems will enable real-time coordination between distributed generation, such as rooftop and community solar assets and bulk power generation, while proactively shaping electric load. This will alleviate periods of costly peak demand, reduce wasted energy, and increase renewables penetration on the grid.

Partnering Institution(s): University of California, San Diego (UCSD) (Lead)


Project Summary:The University of California, San Diego will develop a new datacenter network based on photonic technology that can double the energy efficiency of a datacenter. Their LEED project mirrors the development of CPU processors in PCs. Previous limitations in the clock rate of computer processors forced designers to adopt parallel methods of processing information and to incorporate multiple cores within a single chip. The team envisions a similar development within datacenters, where the advent of parallel lightwave networks can act as a bridge to more efficient datacenters. This architecture leverages advanced photonic switching and interconnects in a scalable way. Additionally, the team will add a low-loss optical switch technology that routes the data traffic carried as light waves. They will also add the development of packaged, scalable transmitters and receivers that can be used in the system without the need for energy-consuming optical amplification, while still maintaining the appropriate signal-to-noise ratio. The combination of these technologies can create an easily controllable, energy-efficient architecture to help manage rapidly transitioning data infrastructure to cloud-based services and cloud-based computing hosted in datacenters.

Transformational Merit: If successful, developments from ENLITENED projects will result in an overall doubling in datacenter energy efficiency in the next decade through deployment of new photonic network topologies.
