Antora Energy

Thermal energy storage for industrial heat

Overview

Antora Energy provides zero-carbon heat and power for heavy industry by storing renewable energy as heat using thermal energy storage with carbon blocks as a thermal battery. Excess solar and wind energy is converted into heat and stored, then delivered on demand as electricity or industrial process heat up to 1500°C. This approach targets industries that require large amounts of heat, offering a practical decarbonization option where traditional batteries can’t reach the necessary temperatures or durations. The goal is to scale affordable renewable energy storage for heavy industry, unlocking a large multi-trillion-dollar market opportunity.

Simplify's Take

What believers are saying

  • POET’s 5 GWh project validates utility-scale demand for continuous industrial heat.
  • Grok Ventures financing de-risks first-of-a-kind deployment and future project financing.
  • ARPA-E funding and Con Edison partnership strengthen credibility with regulated industrial customers.

What critics are saying

  • Project Big Stone depends on one external financier, concentrating rollout risk in Grok Ventures.
  • TPV performance and durability remain unproven at scale, limiting electricity revenue.
  • Each deployment needs bespoke financing, slowing expansion beyond expensive project-by-project sales.

What makes Antora Energy unique

  • Antora stores renewable electricity as glowing-hot carbon blocks, reaching 1500°C or higher.
  • Its thermal battery delivers both process heat and electricity through thermophotovoltaics.
  • Factory-built modular units target rapid replication across thousands of industrial sites.

No Solar Energy? No Problem! Gigantic Undersea Cable Will Make It Happen

Sign up for daily news updates from CleanTechnica on email. Or follow us on Google NewsThe Intertubes absolutely lit up earlier today, when the Australian government finally green-lighted the massive, long awaited Australia-Asia Power Link solar energy project. Under the purview of the startup SunCable, AAPowerLink will connect the nation’s vast solar resources to the energy-hungry island of Singapore by undersea cable. The private sector venture may seem quixotic at first glance, but the technology pieces are in place — it’s just a matter of next steps.Solar Energy By (Very) Long Undersea Cable: Not A DreamThe idea of transporting solar energy by undersea cable is a relatively new twist on an old idea. The use of submarine cables for transporting renewable energy is commonplace, partly by virtue of the offshore wind industry.Long undersea cables are also commonplace and they are getting longer, especially in the field of data transmission. The new Meta undersea cable project circumnavigating Africa, for example, is 45,000 kilometers (about 27,961 miles) long
