OPEN 2018

Open Funding Solicitation

In 2018, ARPA-E issued its fourth open funding opportunity, designed to catalyze transformational breakthroughs across the entire spectrum of energy technologies. ARPA-E received thousands of concept papers for OPEN 2018, which hundreds of scientists and engineers reviewed over the course of several months. ARPA-E selected 45 projects for its OPEN 2018 program, awarding them $112 million in federal funding. OPEN 2018 projects cut across ten technology areas: building efficiency, distributed generation, electrical efficiency, grid, grid storage, manufacturing efficiency, resource efficiency, transportation fuels, transportation energy conversion, and transportation vehicles.

ABB, Inc.

Economical Data-Fused Grid Edge Processor (EDGEPRO) For Future Distribution Grid Control Applications

ABB Inc. will design a low-cost, secure, and flexible next-generation grid service platform to improve grid efficiency and reliability. This technology will merge advanced edge computing, data fusion and machine learning techniques for virtual metering, and create a central repository for grid applications such as distributed energy resource (DER) control and others on one platform. The united platform will consist of four functional layers: (1) communication including data collection and exchange, (2) data processing and distributed state estimation, (3) data standardization and storage, and (4) hosted grid applications designed to enable large-scale deployment of DERs and more flexible grid control. ABB's approach will integrate and maximize emerging technologies in the transition to a decentralized and distributed electric grid.

Achates Power, Inc.

Highly-Efficient Opposed Piston Engine for Hybrid Vehicles ("HOPE-Hybrid")

Achates Power will develop an opposed-piston engine suitable for hybrid electric vehicle applications. The team will use a unique gasoline compression ignition design that minimizes energy losses (e.g., heat transfer) typical in conventional internal combustion engines. A motor-generator integrated on each engine crankshaft will provide independent control to each piston and eliminate all torque transmitted across the crankshaft connection, thus reducing engine size, mass, cost, friction, and noise. Engine efficiency improvement is expected through this real-time control of the combustion process. The proposed technology has the potential to offer manufacturers a full-range of cost-effective solutions to improve vehicle efficiency and reduce CO2 emissions.A highly efficient hybrid opposed-piston engine can be easily integrated in the existing fueling infrastructure and offers the power and convenience that U.S. consumers demand.

AltaRock Energy Inc.

Millimeter Wave Technology Demonstration for Geothermal Directed Energy Drilling

AltaRock Energy will overcome technical limitations to deep geothermal drilling by replacing mechanical methods with a Millimeter Wave (MMW) directed energy technology to melt and vaporize rocks for removal. This approach could increase drilling speed by 10 times or more, reducing costs while reaching higher temperatures and greater depths than those achievable with the best current and proposed mechanical technologies. Project R&D will include benchtop testing as well as larger scale demonstrations of directed MMW drilling at unprecedented borehole lengths and power levels. A detailed modeling and simulations campaign carried out with the experimental work will provide the basis for the design of larger, commercial-scale systems.

Aquanis, Inc.

Active Aerodynamic Load Control for Wind Turbines

Aquanis will develop advanced plasma actuators and controls to reduce aerodynamic loads on wind turbine blades, facilitating the next generation of larger (20+ MW), smarter wind turbines. The technology contains no moving parts, instead using purely electrical plasma actuators on the blade that set the adjacent air in motion when powered. This system can change the lift and drag forces on turbine blades to reduce blade mechanical fatigue and enable the design of larger and cheaper blades. Currently effective at laboratory scales, Aquanis plans to improve the plasma actuator capabilities and field test a prototype plasma actuator system on a wind turbine.

Arizona State University

Mining Air for Fuels and Fine Chemicals (MAFF)

ASU will collect CO2 from air using a low-cost polymer membrane-based DAC process. The team will use water evaporation to drive to capture CO2, decrease emissions, and improve the energy efficiency of the overall carbon capture process. The project will use novel materials to create high-surface area membranes to continuously and actively pump CO2 against a concentration gradient. The process will capture distributed CO2 emissions that can be sequestered or converted into a wide range of energy-dense fuels, fuel feedstocks, or fine chemicals.

Arizona State University

Sensor Enabled Modeling of Future Distribution Systems with Distributed Energy Resources

Arizona State University will develop learning-ready models and control tools to maintain sensor-rich distribution systems in the presence of high levels of DER and storage. This approach will include topology processing algorithms, load and DER models for system planning and operation, distribution system state estimation, optimal DER operational scheduling algorithms, and system-level DER control strategies that leverage inverter controls' flexibility. The project will alter distribution system operation from today's reactive, load-serving, and outage mitigation-focused approach to an active DER, load, and outage-managed, market-ready approach.

Brayton Energy

Low-Cost Dispatchable CSP Engine For Residential Power

Carnegie Mellon University

Additive Manufacturing of Spacer Grids for Nuclear Reactors

Carnegie Mellon will combine its expertise in additive manufacturing (AM) with Westinghouse's knowhow in nuclear reactor component fabrication to develop an innovative process for AM of nuclear components. The team chose to redesign nuclear reactor spacer grids as a test case because they are a particularly difficult component to manufacture. The role of spacer grids is to provide mechanical support to nuclear fuel rods within a reactor and reduce vibration as well as cause mixing of the cooling fluid. The team will alter the traditional AM process, including using nonstandard powders to optimize performance and reduce cost. If the project is successful, it could pave the way for other reactor components to be additively manufactured, enabling the rapid deployment of advanced reactors.

Colorado School of Mines

Efficient Hydrogen and Ammonia Production via Process Intensification and Integration

The Colorado School of Mines will develop a more efficient method for both the conversion of hydrogen and nitrogen to ammonia and the generation of high purity hydrogen from ammonia for fuel cell fueling stations. Composed of 17.6% hydrogen by mass, ammonia also has potential as a hydrogen carrier and carbon-free fuel. The team will develop a new technology to generate fuel cell-quality hydrogen from ammonia using a membrane based reactor. In addition, similar catalytic membrane reactor technology will be developed for synthesis of ammonia from nitrogen and hydrogen at reduced pressure and temperature. This is aided by selective removal of ammonia, which enables equilibrium limitations to be surpassed, a fundamental constraint in conventional Haber-Bosch ammonia synthesis.

Creare LLC

CTFusion, Inc

Plasma Driver Technology Demonstration for Economical Fusion Power Plants

CTFusion is developing an early-stage approach to a commercially viable fusion power plant. The company will pursue higher performance in a compact fusion configuration called a spheromak through targeted upgrades of an existing plasma system. The project aims to demonstrate the required physical parameters, engineering performance, and scalability of the team's fusion concept toward an eventual electricity-producing, economical fusion power plant. CTFusion plans to 1) provide an integrated demonstration of its novel plasma sustainment method called imposed-dynamo current drive (IDCD) and 2) confirm the scalability of spheromaks sustained with IDCD toward eventual power plant conditions. Fusion energy has the potential to be a game-changing energy source that is plentiful, safe, and environmentally friendly, producing no harmful emissions. It could work together with renewable energy technologies to provide an economic, clean, and secure energy solution.
