Bhutan has officially declined an offer from Indian Oil Marketing Companies to supply E20 petrol. This rejection occurs amidst discussions in India regarding the government’s proposal for E20 petrol, which is a blend of 20 per cent ethanol and 80 per cent petrol. The Bhutanese government has requested that India maintain the supply of conventional petrol as long as it remains available in the Indian market.

Concerns Over Fuel Storage Infrastructure

The primary reason for Bhutan’s refusal to accept E20 petrol is its ageing fuel storage system, which is not adequately equipped to manage ethanol-blended fuel. Specifically, Bhutan’s underground storage tanks are susceptible to water contamination, which can lead to significant performance issues. These concerns are exacerbated by Bhutan’s rugged terrain, where vehicles require optimal power and consistent performance for safe travel.

A Bhutanese official highlighted that E20’s hygroscopic nature makes it prone to absorbing moisture, increasing the risk of water contamination in the fuel. If water enters the fuel tanks, it may cause the E20 to dilute, complicating separation and leading to potential engine malfunctions, which is particularly critical for vehicles navigating the nation’s challenging roads.

Officials have expressed anxiety over the implications of introducing E20 fuel, given the current state of the underground tanks. The Bhutanese government has indicated that they would prefer to be notified in advance should Indian OMCs consider higher levels of ethanol blending in the future.

The Wider Context of E20 Petrol in India

The introduction of E20 petrol in India has sparked controversy, particularly among owners of petrol vehicles manufactured before 2023. Complaints include diminished fuel efficiency, increased maintenance needs, and greater wear on vehicle parts. While the government acknowledges a slight drop in mileage with E20, it claims that the benefits in terms of better acceleration and engine performance outweigh these drawbacks.

Bhutan heavily relies on India for its fuel supplies, currently purchasing higher-export-quality petrol and diesel, which are generally costlier than what is available at Indian petrol stations. As India advocates for the deployment of E20 petrol, Bhutan’s reliance on Indian fuel could intensify the impact of this shift, making the decision to decline an offer even more consequential.

In a recent Supreme Court hearing, the Indian government described the E20 petrol initiative as an “experiment,” with results expected next year. This assertion triggered considerable backlash, prompting the government to deny the statement. However, a video of the Attorney General’s remark has circulated widely, igniting further discussion about the implications of E20 adoption.

Future Considerations for Bhutan

As the discourse around E20 petrol continues in India, Bhutan’s stance illustrates the complexities of fuel infrastructure and vehicle performance in a mountainous region. The Bhutanese government’s current position on ethanol-blended fuel reflects a cautious approach, prioritising the maintenance of fuel quality and vehicle reliability over the adoption of new fuel policies.

Bhutan has clarified its interest in remaining informed about any future initiatives regarding ethanol blending from Indian OMCs, indicating its intent to reassess the situation as infrastructure and technology potentially improve. Such developments could influence Bhutan’s fuel strategy as it aims to align with regional fuel standards without compromising on performance and safety for its drivers.

In conclusion, Bhutan’s refusal to accept the E20 petrol offer underlines the nation’s logistical challenges and prioritises fuel integrity, thereby reinforcing the need for robust fuel storage systems in the face of evolving energy policies in the region.
