Decarbonizing Heavy Industry:
Capture, Heat, and the Circular Factory
Steel, cement, and chemicals underpin everything the modern economy builds — and together they emit more than any single country except China and the US. The technologies to clean them exist at pilot scale; the work of this decade is making them pencil at industrial scale. This brief curates the research mapping that path.
The path we're on
Industrial emissions are the hardest fifth of the problem
Industrial heat runs above 1,000 °C, capital assets live for forty years, and margins are thin — three reasons the sector has moved slower than power or transport. Every kiln and furnace ordered this decade locks in its emissions profile to mid-century, which makes the current investment cycle the one that counts.
Where industrial emissions come from
- Process heat — the high-temperature core of steel, cement, and chemical production.
- Process chemistry — CO₂ released by the reactions themselves — clinker calcination, iron reduction.
- Value-chain leakage — upstream fuels and downstream waste that never re-enter the loop.
Why it matters
Whoever industrializes clean steel, cement, and chemicals first sets the standard everyone else licenses. Green premiums are narrowing as carbon border adjustments arrive, and offtake agreements — not pilots — are becoming the scarce resource. Capital is watching for the projects that clear bankability.
“The factories that will pour the world's 2050 concrete are being financed now — clean process heat is the deal term to watch.”

Key focus areas
Where the next decade of work concentrates
Clean industrial heat
Electrified furnaces, thermal batteries, and hydrogen combustion that reach process temperatures without the fuel — the single largest lever in the sector.
Carbon capture at the stack
Point-source capture retrofits for cement and steel where process chemistry makes some CO₂ unavoidable — paired with transport and storage networks that are finally being permitted.
Circular materials
Scrap-based steelmaking, clinker substitution, and chemical recycling that shrink the raw-material intensity of every ton produced.
The most viable solutions will:
- Drop into existing plants — retrofit economics beat greenfield in a sector allergic to downtime.
- Hit cost parity within a contract cycle — offtakers sign for green premiums measured in percent, not multiples.
- Survive commodity cycles — business models that hold when steel and cement prices swing.
