The LNG Cold Chain: Why Liquefying Gas Costs a Quarter of Its Value

In early March, a US cargo captain waiting off Sabine Pass had a decision to make that had nothing to do with weather. Henry Hub gas was trading near 2.97 dollars per million British thermal units. The same energy, delivered as liquefied gas into Northwest Europe, was worth about 17 dollars at the Dutch TTF benchmark, and roughly 15.50 into Asia at the JKM marker. That spread is the entire reason the LNG business exists. It is also, almost exactly, the reason it is so hard to make money in.

Turning a gas into a liquid you can put on a ship is not a shortcut. It is a full industrial relay: treat the gas, chill it to minus 162 Celsius, load it into insulated tanks, sail it thousands of miles, then boil it back into gas at the far end. Each stage costs real money and real energy, and each one takes a bite out of that headline arbitrage before a single dollar of profit reaches anyone.

Where the money goes

Break down the operating cost of moving gas by sea and the shape is consistent across the industry. Refrigeration and liquefaction absorb roughly 40 to 42 percent of the chain's operating cost. Shipping runs 20 to 30 percent. Regasification and distribution at the receiving end take another 20 to 27 percent. Liquefaction is the heavyweight, and it is the reason the plant, not the ship, is where the capital piles up.

Put that in per-unit terms and it stops being abstract. Liquefaction fees on long-term US deals have run from about 2.25 to 3.50 dollars per MMBtu. Ocean freight typically adds 0.50 to 1.20 dollars. Regasification at the import terminal adds another 0.30 to 1.00 dollar, with a simple floating-storage-and-regas unit sitting at the cheap end. Stack those together on top of the feedgas cost and a fair chunk of the delivered price, often around a quarter of it in a normal market, is just the toll for changing the gas's physical state and getting it across the water.

Cold is the expensive part

The reason liquefaction dominates is thermodynamics. To hold methane as a liquid you have to strip out about 600 volumes of gas into one volume of liquid and keep it there at cryogenic temperature. That takes enormous compressor trains, refrigerant loops, and power, and the plants that do it are among the largest single capital projects in energy. Liquefaction terminals are built to run for decades because the only way to justify the up-front spend is to spread it across twenty years of throughput.

Shipping looks cheaper on the operating line, but that is misleading. An LNG carrier is a purpose-built vessel with double-walled cryogenic tanks, and its cargo is quietly boiling off the whole voyage. Freight cost is also the swing factor that decides whether a trade even happens. A wider canal queue at Panama, a Suez reroute, or a spike in charter rates can quietly eat an entire regional price gap, which is why traders watch freight as closely as they watch the commodity.

Two ways to split the risk

How that cost gets divided between seller and buyer depends on the contract, and there are two broad families. US export deals are mostly tolling structures. The buyer pays a variable charge tied to the American gas price, commonly modeled as about 115 percent of Henry Hub to cover feedgas plus liquefaction energy, and on top of that a fixed liquefaction fee, usually somewhere in the 2 to 3 dollar range. Recent long-term deals have landed inside that band; a 20-year agreement signed last year between ADNOC and the Rio Grande developer NextDecade was reported with a fixed fee around 2.40 to 2.55 dollars.

The other family is oil-indexed. Much of the legacy supply out of the Middle East, Australia, and elsewhere prices LNG off a slope to Brent crude rather than off a gas hub. The two structures allocate risk very differently. In a Henry Hub tolling deal, the buyer carries the commodity risk and the seller banks a fixed fee for use of the plant. In an oil-indexed deal, the price moves with crude regardless of what gas is actually doing in either basin.

That distinction has teeth. In a US tolling deal the seller's margin is the gap between feedgas cost and what the cargo fetches downstream, and that gap is not something you can cleanly hedge. As one market analysis put it plainly, the flexibility you cannot hedge is open risk. When Henry Hub climbs, the feedgas leg climbs with it and the exporter's margin compresses even if the fixed fee never moves.

Why the same cargo sails east or west

The tolling structure comes with a feature that turns every flexible US cargo into a live trading decision: destination flexibility. The buyer, having paid the fixed fee, can send the ship wherever the math is best. That math is the netback, the delivered price in a region minus the freight to get there. Compare the Europe netback against the Asia netback and you send the cargo to whichever is higher.

This is where the JKM-TTF-Henry Hub triangle does its work. Henry Hub sets the cost of the molecule leaving the US. TTF and JKM set what it is worth arriving in Europe or Asia. When JKM runs above TTF by more than roughly 3 dollars per MMBtu, Asia's premium is wide enough to cover the longer haul and the extra freight, and cargoes tend to swing east, tightening Europe and pulling TTF up behind them. When the spread narrows or freight rises, Europe wins on netback and the ships stay closer to home.

That was exactly the situation this past March. High freight and a compressed JKM-TTF spread pointed the front-month US arbitrage at Europe, even as some cargoes began peeling off toward Asia as the eastern premium firmed. The decision flips week to week because the inputs, three benchmarks and a freight rate, move week to week.

The takeaway for the desk

LNG is often described as a way to connect cheap gas to expensive markets. That is true, but it undersells how thin the connection can get. The cold chain skims off a liquefaction fee, a freight bill, and a regas charge before anyone books a profit, and in a normal market those tolls add up to something close to a quarter of the delivered value. The trade only clears when the inter-basin spread is comfortably wider than the full cost of the relay.

That is why this business runs on spreads, not on absolute prices. A 15-dollar delivered price in Asia means nothing on its own; what matters is whether it beats the European netback after freight, and whether either beats the loaded cost coming out of the Gulf. When those gaps are wide, the ships choose their destination mid-ocean and the model prints money. When they narrow, the same fixed costs that make the chain possible are what make it stop paying.
