Nb 3 Sn Superconducting RF Cavities: R&D Progress at Fermilab and Opportunities

Nb 3 Sn becomes superconducting at twice as high temperature as our standard SRF material niobium. This allows us to efficiently operate Nb 3 Sn cavities at 4.4 K instead of the usual 2 K. This reduces cryogenic costs and even makes it possible to use a cryocooler instead of a large, complex cryogenic plant. The superheating field H sh of Nb 3 Sn is twice that of niobium. H sh is thought to be the ultimate limit for a defect-free superconductor. Nb 3 Sn cavities being made today are still about a factor of 4 away from this ultimate limit, but R&D has been leading to substantial progress towards this goal.

Wood-to-Fuel for California's Transportation Sector using Autothermal Pyrolysis (FRD-17-002 Progress Report)

In the month of December, we planned to have the Site License Agreement with SPI from them for final signatures, make further progress on the market assessment for the Wood-to-Bio-oil Market Report, and continue moving towards getting the subcontracts in place with Iowa State University and Frontline BioEnergy, LLC. The hope was to be able to get the finalized Site License Agreement back from SPI/Gary Blanc this month. Unfortunately, since we were in the immediate aftermath of fire season in California, and Gary was still unavailable as a result, we did not. Thankfully, it does not appear that there will be any major difficulties with getting the agreement finalized and signed, once Gary is available again, as SPI is constant in their support and eagerness for this effort to go forward, so we are not concerned that this is a risk to the project at this time. During the month of December, further research was completed on understand and evaluating the availability and potential availability of fire clearing, and other, forestry residue in California. Further investigations into the negative emissions of biomass pyrolysis products and their upgrading for use in other products (such as fuels) by incorporating carbon capture, drying and compression, and sequestration systems were conducted. The cost to achieve the maximum amount of negative emissions from these biomass-pyrolysis products with carbon capture and sequestration techniques was calculated. Sensitivity analysis was employed to understand how feedstock collection cost and product selling price affects this cost. We continued with the process towards subcontracting with Iowa State University and Frontline BioEnergy. Increased emphasis was placed on getting an updated budget from Frontline BioEnergy, LLC., so it can be submitted for approval of replacing a subcontractor, as we understand this is of utmost importance to the CAM. Frontline reported being very close to an updated budget, waiting on contracted labor costs remaining.

Progress on Synthesis of Low Content Inert Matrix Fuel Pellets

Progress was made on optimizing hot-press parameters for preparing fuel for two different coating methods: chemical vapor deposition (CVD) and chemical vapor infiltration (CVI). Surrogate materials, CeO 2 and ZrO 2 , were used in place of UO 2 and PuO 2 for fuel development. Although the more porous CeO 2 pellets were not successfully made to the extent that CVI would work with them as intended, hot-press parameters were optimized such that the pellets could be coated using CVD. The ZrO 2 was denser and therefore could more successfully be pressed to CVI standards; however, further improvement is needed before the process is implemented. Future work will continue to explore the optimization of a porous structure for CVI.

Batteries Annual Progress Report (FY2019)

The Vehicle Technologies Office (VTO) of the Department of Energy (DOE) conducts research and development (R&D) on advanced transportation technologies that would reduce the nation’s use of imported oil and would also lead to reductions in harmful emissions. Technologies supported by VTO include electric drive components such as advanced energy storage devices (primarily batteries), power electronics and electric drive motors, advanced structural materials, energy efficient mobility systems, advanced combustion engines, and fuels. VTO is focused on funding early-stage high-reward/high-risk research to improve critical components needed for more fuel efficient (and cleaner-operating) vehicles. One of the major VTO objectives is to enable U.S. innovators to rapidly develop the next generation of technologies that achieve the cost, range, and charging infrastructure necessary for the widespread adoption of plug-in electric vehicles (PEVs). An important prerequisite for the electrification of the nation’s light duty transportation sector is development of more cost-effective, longer lasting, and more abuse-tolerant PEV batteries. One of the ultimate goals of this research, consistent with the current vehicle electrification trend, is an EV which can provide the full driving performance, convenience, and price of an internal combustion engine (ICE) vehicle. To achieve this, VTO has established the following overarching goal (Source: FY2021 Congressional Budget Justification1): …identify new battery chemistry and cell technologies with the potential to reduce the cost of electric vehicle battery packs by more than half, to less than $100/kWh (ultimate goal is $60/kWh battery cell cost), increase range to 300 miles, and decrease charge time to 15 minutes or less by 2028. VTO works with key U.S. automakers through the United States Council for Automotive Research (USCAR) – an umbrella organization for collaborative research consisting of Fiat Chrysler Automobiles (FCA), the Ford Motor Company, and General Motors. Collaboration with automakers through the partnership known as U.S. Driving Research and Innovation for Vehicle Efficiency and Energy Sustainability (U.S. DRIVE) attempts to enhance the relevance and the success potential of its research portfolio. VTO competitively selects projects for funding through funding opportunity announcements (FOAs). Directly-funded work at the national laboratories are awarded competitively through a lab-call process. During the past year, VTO continued R&D in support of PEVs. Stakeholders for VTO R&D include universities, national laboratories, other government agencies and industry (including automakers, battery manufacturers, material suppliers, component developers, private research firms, and small businesses). This document summarizes the progress of VTO battery R&D projects supported during the fiscal year 2019 (FY 2019).
