DOE HPC4Mfg program funds 13 projects to advance US manufacturing; welding, Li-S batteries among projects
31 August 2016
A US Department of Energy (DOE) program designed to spur the use of high performance supercomputers to advance US manufacturing has funded 13 new industry projects for a total of $3.8 million. Among the projects selected are one by GM and EPRI of California to improve welding techniques for automobile manufacturing and power plant builds in partnership with Oak Ridge National Laboratory (ORNL).
Another one of the 13 projects is led by Sepion Technologies, which will partner with LBNL to make new membranes to increase the lifetime of Li-S batteries for hybrid airplanes.
The High Performance Computing for Manufacturing (HPC4Mfg) Program creates an ecosystem that allows experts at DOE’s national laboratories to work directly with manufacturing industry members to teach them how to adopt or advance their use of high performance computing (HPC) to address manufacturing challenges with a goal of increasing energy efficiency, reducing environmental impacts and advancing clean energy technologies.
The partnerships use world-class supercomputers and scientific expertise from Lawrence Livermore National Laboratory (LLNL), which leads the program, and partner laboratories Lawrence Berkeley and Oak Ridge national laboratories (LBNL and ORNL), which in turn team up with US manufacturers.
GM and EPRI. GM and EPRI, representing two major US manufacturing industry sectors (automotive and nuclear energy) and both having welding research & development capabilities, will work with Oak Ridge National Laboratory (ORNL) for the purpose of advancing HPC weld modeling tools for broad industrial applications.
This potential will be demonstrated with two representative welded structural components:
the prediction of welding-induced dimensional changes and stresses during laser welding assembly of a complex roof panel made of high-strength lightweighting materials; and
the prediction of weld residual stresses in the dissimilar welds of nuclear piping systems.
The goal is to reduce the computational time of the two above examples from days or months to several hours while providing adequate solution accuracy so that the HPC weld modeling tools could effectively optimize welding technology in order to minimize dimensional distortion and proactively mitigate the detrimental impact of weld-induced residual stresses.
Sepion. Efforts to commercialize light-weight, energy-dense lithium-sulfur secondary batteries (2510 Wh kg–1) have been stalled by ongoing problems with the battery’s membrane, which limits cycle-life.
Sepion’s polymer membrane technology provides a counterpoint, yielding long-lasting lithium-sulfur cells. Advancing to 10 Ah battery prototypes, Sepion faces challenges in membrane manufacturing related to polymer processing and the molecular basis for membrane performance and durability.
High-performance computing offers critical new insight into these phenomena, which in turn will accelerate the product’s entry into the market. Sepion envisions that successes could catalyze a transformation in aviation, in which fuel-burning aircraft are replaced with hybrid-electric planes featuring 30–50% reductions in fuel costs and emissions.

As the program broadens, other national laboratory partners are expected to join.
