Finalist Electrified Thermal Pitches at Startup Battlefield | TechCrunch Disrupt 2023

Main summary

Key takeaways

Business

Company / Product Overview

  • Electrified Thermal Solutions (ETS) is commercializing Dual Hive, an industrial electric thermal battery that converts cheap/abundant intermittent electricity (solar, wind, nuclear, hydro) into high-temperature hot gas for heavy industry decarbonization.
  • Target industries include cement, steel, glass, adhesives, and food & beverage. Also discussed: ethanol, drywall, ethanol plants, and chemical multinationals.
  • Core technology: e-brick (electrically conductive fire brick) made from ordinary fire brick using semiconductor doping, enabling longer life and higher temperatures than conventional electric heating materials.
  • Deployment model: co-located “on-site” thermal storage/heat generation near existing furnaces/boilers/kilns to avoid piping high-temperature heat long distances.

Value Proposition / Economics (as stated)

  • Dual Hive claims to provide industrial heat at ~1,800°C.
  • Performance/competitiveness:
    • Comparable to hydrogen, but “three times or more cost effective.”
    • Beats natural gas in areas where renewables drive electricity prices negative or surplus.
    • Example economics: ~5-year payback (stated for the Midwest) and potential to decarbonize ~80% of energy.
  • They emphasize parity is electricity-price dependent, but adoption becomes feasible as renewables costs decline.

Business Strategy & Go-To-Market (GTM)

  • Start with “juicy” first customers: big multinational chemical companies and other industrial firms with:
    • Decarbonization mandates / regulatory pressure
    • Simpler integration needs
    • Ability to benefit even in regulated utility environments
  • Sales funnel: move from letters of intent (LOIs) to binding contracts.
  • Build-first rollout:
    • First system planned for 2025 on customer sites (demo/test case under their control).
    • Customer-site deployment planned for 2026 as contracts trigger buildouts.
  • Commercial approach options:
    • Direct sale (customers operate the system)
    • Maintenance contract
    • Heat-as-a-service (ETS operates and sells heat output)

Product / Operations (How it works)

System architecture (“jewel/Dual Hive”)

  • Giant electric heater → thermal store (hot mass)
  • Giant heat exchanger → flow hot gas through existing process equipment

Retrofit positioning

  • ETS positions it as plug-in rather than a redesign:
    • “We plug into your furnace, boiler, kiln”

Scale-up path

  • Lab test rigs → pilot-scale → shipping-container size
  • Shipping-container “first units” → tall towers for hundreds of MW

Manufacturing scaling milestones

  • Moved from powders to full brick pressing capabilities
  • ~1,000X scaling in the last year to ~0.5 ton of conductive bricks (as stated)

Pilot commissioning

  • Pilot commissioned “this past summer”
  • Bricks electrically heated to 1700°C
  • Test conditions designed to match expected customer operating conditions for the battery

Frameworks / Playbooks Mentioned

  • No explicitly named frameworks (e.g., OKRs, SWOT) were used in the subtitles.
  • Implied operational playbook:
    • Modular scaling ladder: lab → pilot → shipping container unit → MW-scale towers
    • Customer validation loop: negotiate a test case with specified flow rates & temperatures, prove performance in the first box, then convert to purchase

Key Metrics / KPIs & Targets (explicit)

Temperature

  • Up to ~1,800°C (claimed capability)
  • Pilot testing at ~1,700°C
  • One integration example: customer needs about ~900°C

System power

  • First product size: ~5 MW in/out

Payback

  • ~5-year payback (Midwest example)

Decarbonization impact

  • ~80% of energy decarbonized (example region/case)

Growth / company deployment targets

  • Deploy 2 gigawatts
  • $500M/year revenue by 2030
  • Ultimate vision: Dual Hive at every furnace/boiler/kiln by ~2045
  • Market size cited: ~$3 trillion

Concrete Examples / Case References

  • Chemicals in Europe (regulated and non-ideal pricing):
    • Customers seek the cheapest compliance path; ETS claims it stays cost-competitive while accounting for utility constraints.
  • Midwest renewable surplus / negative pricing zones:
    • Highlighted as the key to beating natural gas.
    • Named areas/states include Texas and the Midwest (e.g., Wisconsin, Iowa).
  • First customers as test-site deployments:
    • ETS will prove specific flow rates & temperatures on the first shipping-container-sized unit before purchase.

Risks / Constraints Highlighted

  • Electricity price dependency: competitiveness is tied to access to cheap surplus electricity (sometimes negative pricing).
  • Integration constraints: customers need on-site real estate for container systems; site fit may vary.
  • Safety positioning:
    • Compared to battery storage, e-bricks are described as “just very hot heat in an insulated box”, with less “electrical reactivity” risk.
    • ETS states the system behaves like an industrial furnace operationally.

Management / Team Notes

  • Founders / presence:
    • Dan Stack: co-founder and CEO
    • Dr. Joey Cable: co-founder (not present; expecting first child)
  • Invention/patents:
    • Dan Stack says he worked on the technology at MIT since 2014
    • MIT holds the patent, and ETS has commercialization exclusivity
