Energy Transition Equipment

Policy-cycle equipment — Praj's ethanol pause is the cautionary tale

Medium capitalFragmented2 listed names covered

Energy-transition equipment (bio-energy, FGD, hydrogen, heat pumps) is where policy stop-start risk is most brutal. Praj's PAT collapsed from ₹283 Cr to ₹24 Cr as ethanol capex paused after the blending target was hit early. Thermax grinds forward more diversified. The lesson: policy TAMs need policy-cycle underwriting.

TAM: Bio-CNG (500 plants target), SAF mandates (1% 2027), green-H2 mission ₹19.7K Cr, FGD retrofits ₹80K Cr — all real but all schedule-elastic.

Demand drivers

  • ▸SAF blending mandates from 2027 (Praj's second act)
  • ▸CBG procurement obligations on city-gas
  • ▸FGD deadlines (repeatedly extended — the problem)
  • ▸Industrial heat-pump/decarb retrofits (Thermax)

Competitive dynamics

  • ▸Praj globally credible in bio-process (licensor economics) but cyclically hostage
  • ▸Thermax vs BHEL/GE in FGD; vs multiple startups in hydrogen — breadth without dominance
  • ▸Global majors (Andritz, Valmet) compete for the same bio-CAPEX

Unit economics

  • ▸EPC-heavy mix keeps OPM at 5-10%; licensing/services the margin hope
  • ▸Praj at 321x trailing P/E only makes sense on SAF-cycle normalization
  • ▸Thermax 10% OPM ceiling until green portfolio matures

Key programs

  • ▸SAF demonstration plants (Praj-IOC)
  • ▸CBG plant pipeline execution
  • ▸Thermax green-H2 electrolyser pilots

What an expert watches

  • ▸SAF mandate notification (the Praj trigger)
  • ▸Ethanol capex restart signals
  • ▸Thermax order-inflow mix shift to green lines
