Coal to Liquids: Coalition’s Latest Energy Brain-Fart Is Their Craziest yet, and that Takes some Doing

Why It Matters

The CTL push threatens to lock Australia into high‑cost, high‑emission fuel production, undermining climate goals and diverting funds from proven renewable and electrification pathways.

Key Takeaways

• Coalition pushes costly coal‑to‑liquids despite cheaper electrification options
• Technology emits ~221 g CO₂/MJ, three times conventional fuels
• Estimated $8 billion cost and 10‑year build time in Australia
• Past projects in South Africa, US, China deemed uneconomic
• Mining subsidies favor diesel, hindering clean‑energy transition

Pulse Analysis

Coal‑to‑liquids technology, originally refined during World War II, converts solid coal into synthetic gasoline or diesel. While it once offered a strategic lifeline for nations lacking oil imports, modern assessments highlight its steep capital requirements and severe carbon intensity. Recent studies from the U.S. National Energy Technology Laboratory place CTL emissions at roughly 221 grams of CO₂ per megajoule—about three times higher than conventional crude‑derived fuels—making it a poor fit for any jurisdiction aiming to meet net‑zero targets.

In the Australian context, the projected $8 billion price tag and a ten‑year construction horizon starkly contrast with the rapid cost declines in wind, solar and battery storage. Electrification of heavy‑duty haul trucks, already underway at companies like Fortescue, can slash the mining sector’s 6 billion litres of diesel consumption without the water‑intensive, polluting processes CTL demands. Moreover, the federal government’s $4 billion annual diesel subsidy further skews the market, rewarding legacy fuels instead of incentivizing clean‑energy alternatives that deliver lower operating costs and fewer emissions.

Politically, the CTL narrative serves as a rallying point for factions resistant to rapid energy transition, framing renewable adoption as a threat to jobs and energy security. However, the global trend favors decarbonisation pathways that leverage abundant renewable resources and emerging hydrogen technologies. For Australia to remain competitive and meet its climate commitments, policy should pivot away from costly, high‑emission stopgaps like CTL and channel investment toward scalable, low‑carbon solutions that align with both economic and environmental imperatives.
