Thailand plans B20, E20 biofuel push and solar subsidy
Thailand will promote wider use of B20 diesel and E20 petrol blends and offer THB50,000 per household for rooftop solar, Prime Minister Anutin Charnvirakul said on November 14, 2026. B20 is running about THB10 a litre cheaper than conventional diesel after excise tax cuts, and the government is considering cutting gasohol 91 pumps in favour of E20 over the longer term.
What this means for you
- Foreign residents who drive or fill up in Thailand may see cheaper B20 and E20 fuel, with B20 priced about THB10 a litre below conventional diesel.
- Households, including foreign residents who own a home, are offered THB50,000 per household towards rooftop solar under the policy.
