Korean giant reveals ‘grave’ fears over Bowen gas scheme - The Australian

Posco Energy, the Korean steelmaker, has expressed serious concerns about the Bowen Basin gas scheme in Queensland, citing what it describes as grave risks to its investment and operations. The company's statement signals doubt about the project's viability or cost structure at a time when Australia is banking on gas as the firming fuel for a renewables-heavy grid.

Where this fits

This reveals a hard constraint on Australia's de facto energy plan. The grid is being built on the assumption that gas will firm variable solar and wind output for decades. But the economics of new gas supply are deteriorating as global LNG markets shift and as major industrial users, the customers gas schemes depend on, grow hesitant about long-term exposure to gas prices and policy risk. A major Korean buyer's cold feet on Bowen signals that the gas-as-backstop model is fragile. Reliability depends on firming; firming is supposed to come from gas; but the investment case for new gas is weakening. That is a cost and reliability pressure.

What it means

Australia is locking in a grid that requires firm power but is losing confidence in the gas supply meant to provide it. Meanwhile, nuclear generation remains prohibited by law. The gap between what the grid needs and what Australia is building to supply it will either force faster deployment of batteries (with their own cost and supply-chain risk, heavily concentrated in China), or leave the system relying on existing gas plants that are ageing. Without either new gas or a legal path to nuclear, the reliability problem has no solution priced into the transition. That is a credibility gap widening in real time.
