U.S. Department of Energy is developing innovative, flexible, and small-scale (1-5 MW), modular gasification systems for converting diverse types of US domestic energy resources into value-added products with greatly reduced or negative CO2 emissions. Production of high purity (>95%) oxygen at modular scale is an enabling technology for successful development and deployment of these systems. Cryog ...

Monitoring and improving the health and quality of soil is a major concern in the agriculture and biofuel industries and the most useful indicator of soil health organic matter content. Thus, measurement of soil organic matter is critical to increasing crop yields while mitigating the environmental impacts of food and biofuel feedstock production. Current methods require growers to rely on costly ...

Computational Storage platforms are emerging as a disruptive enhancement in the data processing ecosystem as they have the potential to address the critical bottleneck of limited I/O bandwidth and high latency between storage and compute nodes in the system hierarchy. This “late coming” technology to the Exascale program has the potential to enhance DOE and the broader government’s leadershi ...

A robust high current cathode will be developed for use with a rugged, high-reliability portable accelerator. The high-power density afforded by the high brightness cathode allows the accelerators to be used in place of gamma ray irradiators. Safe reliable accelerators replace the use of radioactive sources for irradiation in a variety of applications. During Phase I, a prototype cathode will be d ...

Due to heavy ventilation requirements, poultry buildings consume significantly larger heating fuel than most residential and commercial buildings. As a result, energy is often the second-largest cost in poultry production after the feed. Attempts at minimizing these energy costs lead to insufficient ventilation and ultimately result in poor indoor air quality, impacting animal welfare and increasi ...

The proposed project aims at understanding of plasma/catalyst interaction using a commercially scalable plasma reactor design. If successful, this technology will enable utilization of two major greenhouse gases CH4 and CO2, both are highly stable and require high temperatures (>900°C) to produce products like H2, methanol, syngas, jet fuel, olefins, etc., which have a high carbon footprint. Furt ...

Direct air capture DAC of carbon dioxide is a promising technology that can potentially contribute to mitigation of CO2 emissions at scale and can be used as a sustainable carbon feedstock to produce synthetic fuels, chemicals, and construction materials. Current estimates for DAC suggest that it can cost between $300$1,500/tonne of CO2 captured. The proposed project is aimed at developing and opt ...

The objective of this work is to demonstrate GaN-based Junction Barrier Schottky (JBS) diodes using a novel ion implantation process developed in previously ARPA-E funded projects. The centerpiece of our proposed technology is selective area doping via implantation of Mg ions, which leverages our achievements in the ARPA-E PNDIODES program to push into commercial devices. The targeted application ...

The objective of this work is to develop AlN-based Schottky diodes with electrical properties that will drastically reduce forward conduction losses compared to existing high-power diodes. This objective is achieved through ion implantation of Si in AlN, which provides a shallow ntype dopant in the n+ contact layers. Sophisticated point defect control processes are implemented for the controlled, ...
