The most consequential change in how a festival is powered does not happen on stage. It happens in the fuel going into the generator.

Comfort Energy joins Love Tomorrow as a lower-emission energy partner, supplying Blue Diesel (HVO100) to Tomorrowland Belgium. In 2025, the switch from conventional diesel to Blue Diesel began on the main festival site.

A fossil-free main site

In 2025, Tomorrowland Belgium made the switch from conventional diesel to Blue Diesel across the main festival site. For the first time, the main site operated without fossil fuels, running on a fuel that integrates directly into existing generators, with no equipment changes required to make the switch possible.

What Blue Diesel is

Blue Diesel (HVO100, Hydrotreated Vegetable Oil) is produced by treating vegetable oils, animal fats or waste fats with hydrogen under high pressure and temperature. This process, called hydrocracking, removes oxygen from the feedstock and converts the molecules into pure hydrocarbons, producing a clean, low-sulphur diesel that is chemically near-identical to fossil diesel. Based on supplier lifecycle analysis, it produces up to 90% fewer lifecycle CO2 emissions than conventional diesel.

Because Blue Diesel is chemically close to fossil diesel, it runs in existing generators and fuel infrastructure without modification, making it a practical option for events that depend on reliable mobile power.

Blue Diesel is not a substitute for electrification. It is an important part of the solution for applications where electrification remains technically, operationally or economically out of reach today, and potentially tomorrow. For Comfort Energy, the event sector is a growing focus, precisely because of that gap.

In 2026, with the continued support of Comfort Energy, Blue Diesel powers Tomorrowland Belgium main festival site.

In Comfort Energy's words

"The transition to lower-emission energy solutions does not always require new infrastructure. By switching to Blue Diesel, organisations can significantly reduce emissions using the equipment they already operate today. The results achieved at Tomorrowland Belgium show what is already possible at scale."

The road ahead

By 2030, Love Tomorrow aims for all associated festivals to run on certified renewable energy, with all fixed power sourced from verified renewable sources. The partnership with Comfort Energy is a concrete step on that path: practical, measurable and built for what comes next.
