Coal’s comeback, IMO delays, and AI-Iran energy bets: is the transition stalling—or re-routing?

Global coal demand has been rising for the last couple of years, reaching record highs of about 8.8 billion tonnes in both 2024 and 2025, according to the International Energy Agency (IEA). Yet the same data also points to slowing growth and renewed speculation about “peak coal,” as the market digests higher prices, policy pressure, and efficiency gains. The framing of “war, weather & tragedy” underscores that energy security shocks and extreme conditions can temporarily override decarbonization momentum. For investors and policymakers, the key takeaway is that coal is not simply being replaced; it is being re-timed and re-priced across regions and power systems. Strategically, the cluster highlights a transition that is increasingly shaped by geopolitical friction and regulatory fragmentation rather than a single global plan. Wärtsilä’s warning links shipping’s low-carbon fuel shift to delays at the International Maritime Organization (IMO), where a global decarbonization framework failed to be adopted, leaving rules uncertain and uneven. In parallel, the report on the US clean-energy sector becoming “increasingly Chinese” even as relations soured—now changing—signals a shift toward reshoring, diversification, and tighter industrial policy. Finally, the ABC piece tying “AI and Iran” to speeding up the energy transition suggests that technology-driven demand and sanctions-era energy strategy can accelerate deployment in unexpected directions, while also keeping Iran central to regional energy calculations. Market implications span power generation, maritime fuels, and clean-energy supply chains. If coal demand remains resilient into 2026 despite slowing growth, coal-linked exposures—thermal coal contracts, freight tied to coal flows, and utilities with coal-heavy fleets—could see firmer pricing than transition bears expect, even if upside is capped by “peak coal” narratives. The IMO delay risk is likely to pressure low-carbon bunker fuel adoption timelines, supporting near-term demand for conventional marine fuels while increasing volatility in alternative-fuel pricing and infrastructure investment. The US-China clean-energy supply-chain pivot can affect solar, wind, batteries, and grid equipment sourcing, potentially shifting procurement toward non-China suppliers and raising near-term capex costs. AI-driven energy transition themes also raise demand for grid reliability, power electronics, and data-center energy capacity, which can lift demand for electricity generation assets and grid services rather than only renewables. What to watch next is whether the IMO’s regulatory vacuum persists long enough to lock in another cycle of conventional fuel use, and whether national or regional maritime rules fill the gap with competing standards. For coal, the trigger is whether IEA-style demand growth continues to decelerate toward a clear plateau, or whether security/weather shocks re-accelerate consumption into 2026. For clean energy, the key indicator is the pace of US industrial policy and procurement changes that reduce Chinese dependence without stalling project pipelines. For Iran-linked transition acceleration, monitor announcements tying AI infrastructure buildouts to energy procurement, and any policy signals that alter sanctions enforcement or energy export pathways. Escalation would look like renewed energy-security shocks plus further IMO delay; de-escalation would look like credible, harmonized maritime decarbonization timelines and sustained demand deceleration for coal.

Geopolitical Implications

• 01

  Regulatory fragmentation (IMO delays) turns decarbonization into a patchwork, enabling continued leverage for conventional fuel suppliers and complicating enforcement.

• 02

  US-China industrial decoupling pressures clean-energy supply chains, shifting bargaining power toward alternative suppliers and increasing strategic stockpiling incentives.

• 03

  Iran’s role in AI-driven energy transition narratives keeps it embedded in regional energy security calculations, potentially affecting sanctions sensitivity and procurement routes.

• 04

  Energy-security shocks (war/weather framing) can repeatedly override climate policy timetables, increasing volatility in global commodity flows.

Key Signals

• —Any renewed IMO push for a harmonized global shipping decarbonization framework and the timeline for adoption.
• —IEA updates on coal demand growth rates and whether “peak coal” indicators strengthen into 2026.
• —US procurement and subsidy rules that quantify reductions in China-linked clean-energy inputs.
• —Announcements connecting AI/data-center buildouts to specific energy procurement channels involving Iran or Iran-adjacent routes.
