Ethanol Output Cranked up to Meet E20 Demand

Why It Matters

The shift to E20 could halve Thailand’s oil import bill and stabilize retail fuel prices amid global crude volatility. It also unlocks growth for domestic sugarcane and cassava industries, reinforcing energy security.

Key Takeaways

• Ethanol capacity 7.2M L/day, 50‑60% surplus.
• E20 demand could double ethanol use to 6M L/day.
• Government targets 5 baht/L price gap vs gasoline.
• Cassava demand may rise to 6M tonnes annually.
• Sugarcane area 11M rai supports biofuel expansion.

Pulse Analysis

The surge in global crude prices and shipping bottlenecks through the Strait of Hormuz has pushed Thailand to accelerate its bio‑fuel agenda. By promoting gasohol E20—gasoline blended with 20 % ethanol—the government aims to cushion retail fuel costs and lessen dependence on imported oil. Energy officials plan to keep E20 priced at least five baht per litre below conventional gasohol 91 and 95, creating a clear economic incentive for motorists. This price differential is central to the policy’s adoption strategy.

Thailand’s ethanol sector is well‑positioned to meet the anticipated demand. Current production capacity stands at 7.2 million litres per day, with half of that capacity idle, giving manufacturers ample room to scale up without major new investments. Feedstock availability is robust: more than 11 million rai of sugar‑cane plantations generate roughly 90 million tonnes of cane each year, while cassava supplies could be redirected to meet an estimated six million tonnes of ethanol feedstock annually. The resulting boost in bio‑fuel output is expected to double daily ethanol consumption from 3.5 million to over six million litres.

The policy’s success hinges on maintaining the targeted price gap and ensuring consistent feedstock supply. A wider five‑baht differential makes E20 attractive to drivers, potentially shifting a significant share of the 30 million litres of daily gasoline consumption toward the blended fuel. If realized, Thailand could cut oil imports by several hundred thousand barrels per day, strengthening its trade balance and reducing exposure to geopolitical shocks. However, scaling cassava usage must avoid disrupting food‑price stability, and logistics for ethanol distribution will need coordination across the country’s 28 production plants.
