ARPA-E’s history and mission
Timeline: • 2007: Rising Above the Gathering Storm report • 2009: American Recovery & Reinvestment Act Signed – ARPA-E’s first appropriations of 425M
Goal 1: Overcome long-term and high-risk technological barriers in the development of energy technologies that…
- REDUCE IMPORTS
- IMPROVE EFFICIENCY
- REDUCE EMISSIONS
Goal 2: Ensure that the U.S. maintains a technological lead in developing and deploying advanced energy technologies.
Framing of fusion energy within ARPA-E’s program portfolio
Framing of fusion energy within ARPA-E’s program portfolio
‣ Fusion energy sits at arguably the highest-risk, highest-impact end of ARPA-E’s entire energy-technology portfolio – Fusion has the potential to be a high-power-density, firm, low-carbon energy source that can possibly be sited near dense population centers – Fusion can potentially disrupt the way humans generate and use energy
‣ Fusion is valuable risk mitigation for the world to achieve cost-effective “net-zero” GHG emissions while meeting growing energy demand and electrification – There are a limited number of low-carbon, primary-energy solutions, all with significant technical and/or socio-economic challenges: • Renewables + long-duration storage • Advanced nuclear fission • Fossil fuels with carbon capture, utilization, sequestration (CCUS) • Enhanced geothermal • + fusion?
ARPA-E fusion timeline/programs

• 2013: Program Director Dr. Pat McGrath decides to develop a fusion program • 2015: ALPHA program (Ref: C. Nehl et al., “Retrospective of the ARPA-E ALPHA Fusion Program,” J. Fusion Energy 38, 506 (2019)) • 2018: OPEN 2018 (77 projects, included three fusion projects) • 2019: Diagnostic “capability teams” • 2020: BETHE; GAMOW (joint with DOE Fusion Energy Sciences)
Thought process behind new ARPA-E fusion programs
Thought process behind new ARPA-E fusion programs
Aspiration: catalyze a new trajectory toward commercially viable DEMO on a two-decade time scale.
Technical drivers: • More low-cost approaches at higher levels of fusion performance -> BETHE (+ diagnostic teams) • Innovative solutions from the first wall to the heat exchanger -> GAMOW (joint with FES)
Programmatic drivers: • Engage larger portion of the fusion R&D community • Leverage SotA expertise/capabilities • Incentivize publicly and privately funded teams to work together
BETHE* program: Catalyze R&D to deliver a larger number of lower-cost fusion concepts at higher performance levels
BETHE* program: Catalyze R&D to deliver a larger number of lower-cost fusion concepts at higher performance levels *Breakthroughs Enabling Thermonuclear-fusion Energy
Advance the performance of lower-cost concepts: • Concept development: – Projected net-gain experiment for ≲ $100M – Specify entry/exit milestones – Funding ceiling commensurate w/ achieved performance – Leverage capability teams – Selected projects include mirrors, spheromak, MIF, Z pinch, µ-catalyzed fusion • Capability teams
Lower the cost of more-mature concepts: • Component technology development: – Potentially enable overnight capital cost <2B, <5/W – Selected projects include fast-ramping tokamak HTS central solenoid, new approaches to stellarator magnets, next-gen high-bandwidth lasers
BETHE portfolio (5M FES): 17 projects across 3 technical categories

Tech-to-Market (T2M) priorities for the ARPA-E fusion portfolio
Tech-to-Market (T2M) priorities for the ARPA-E fusion portfolio
‣ Investor engagement ‣ Market studies (Report: Early Markets For Fusion Energy) ‣ Updated reactor-costing tool, studies, and support of concept teams (Woodruff Scientific) ‣ Engaging NGOs (who will be the advocates for the ultimate commercial adoption of fusion) ‣ Supporting/coaching our project teams (on development plan, team building, securing follow-on funding, etc.)
Summary of findings from ARPA-E report Early Markets for Fusion Energy
Summary of findings from ARPA-E report Early Markets for Fusion Energy
‣ Most-promising early markets are high-priced electricity markets around the world (up to 110/MWh, e.g., Singapore, Japan, California) – Eventually, fusion may need to cost <50/MWh to access very large markets (to compete with natural gas w/CCS and $50/ton carbon tax) ‣ Load-following may not be economically feasible for fusion (it cannot afford to sit idle half the time due to large capital cost) – Integrated thermal storage may be needed so plant can run at high capacity factor ‣ Process-heat and hydrogen-production markets will be tough early markets (also, fusion may not be able to achieve the needed high temperatures) ‣ Desalination & direct air capture alongside power generation or retrofitting coal power plants may help make fusion more economically competitive
