The Assumption Gap: Growth Capital Is Separating Current Economics From Durable Returns

C-MACC Sunday Executive Summary

The Assumption Gap: Growth Capital Is Separating Current Economics From Durable Returns

  • Growth capital is separating current operating economics from durable expansion returns, favoring projects that remain attractive when the conditions supporting today’s results change materially.
  • RWE is committing heavily where customer agreements and capacity mechanisms support earnings visibility, allowing selected power investments to advance without relying entirely on merchant markets.
  • Thyssenkrupp Nucera is retaining SOEC exposure without funding factory-scale production, showing that attractive long-term markets can still lack sufficient orders to support manufacturing at scale.
  • Existing industrial sites gain option value when infrastructure is difficult to recreate, improving selective brownfield economics without making weak incumbent assets more competitive over time.
  • Additionally, strong Asian container volumes increasingly reflect infrastructure and investment goods, leaving port capacity constrained without giving convincing proof of a broad chemical demand recovery.

  • Companies Mentioned: Phillips 66, Kinder Morgan, HF Sinclair, RWE, Thyssenkrupp Nucera, Covestro, Evonik, LyondellBasell, Mosaic, Coromandel, Nutrien, AdvanSix, Intrepid, PureCycle, Borealis, Procter & Gamble, Hapag-Lloyd, Maersk
  • Products Mentioned: Natural Gas, Hydrogen, Phosphate, Fertilizer, Ethane, Propane, Crude Oil, Coal, Diesel, Gasoline, Polypropylene, Polyethylene
