The primary purpose of this workshop was to discuss research opportunities targeting enhanced mineralization of atmospheric carbon as a tool for both sequestration and the liberation of energy relevant elements. The discussions in this workshop could help inform a potential future program in this area.

The purpose of this workshop was for ARPA-E to solicit input from a cross-section of the research community and industry in advance of a potential funding opportunity in this area. We brought together experts in embodied carbon, building design, construction materials, and emerging low carbon materials. Given the complexity and interdisciplinary nature of this space, we sought insights as to which research areas have the greatest potential to significantly store carbon, while also being viable for implementation as construction materials.

The purpose of this workshop was for the scientific, engineering, and industry communities to provide input to ARPA-E in advance of a potential funding opportunity in this area. For this workshop, we envisioned bringing together a community of experts in advanced nuclear fuel cycles, UNF recycling and reprocessing, nuclear safeguards and non-proliferation, repositories, and waste forms. We also reached out to experts in adjacent fields of expertise such as chemical and electrochemical processing, advanced materials, industrial engineering, etc.

The large-scale cultivation of macroalgae (also known as seaweed) is increasingly recognized as a potential solution for removal of greenhouse gases from the atmosphere, the economic bioextraction of nitrogen and phosphorus from eutrophic systems, and a source of carbon-neutral biomass for biofuels and bioproducts. ARPA-E views macroalgae as a robust carbon-negative and resource-efficient feedstock for biofuels and bioproducts that does not compete with existing agricultural land. ARPA-E’s MARINER program targets the development and deployment of new technologies for the economi

This potential program would aim to develop ultrahigh temperature materials that would enable drastic improvements in gas turbine and aircraft engine efficiency as well as operating temperatures of nuclear reactors. Developing such ultrahigh temperature materials might be feasible today because of the availability of modern material research tools including multiscale modeling, machine learning, and in particular the advancement of manufacturing technologies such as additive manufacturing.

The workshop convened leading experts in waste-to-energy, combustion, pyrolysis, and cement to identify technology approaches capable of significantly improving the consistency and value of ash from municipal solid waste incineration through pre- and post-combustion analytics, pre-combustion additives, combustion conditions, and ash processing.

The Rapid Encapsulation of Pipelines Avoiding Intensive Replacement Workshop (REPAIR) workshop sought to reduce costs for replacing bare steel and cast iron gas distribution pipes by fabricating new, “smart” pipes inside the old pipes using robotics, advanced composite materials, and new inspection tools.

ARPA-E sought information regarding promising pathways toward improving the carbon-conversion efficiency of renewable feedstocks to products. This workshop explored opportunities to reduce the lifecycle carbon emissions from biofuel and bioproduct pathways through highly efficient directed flux of biomass carbon into products with minimal carbon loss as CO2. Workshop participants explored how inexpensive clean power can enable novel bioprocess designs that limit or completely avoid carbon loss during biomass conversion.
