HVO – Rehlko Generator Sets

Product Description

Backup power reliability is critical for essential infrastructure such as data centers, hospitals, airports, and smart grids. At the same time, the need to reduce our carbon footprint is more urgent than ever. Rehlko (formerly Kohler) diesel generators offer a tangible, sustainable, and immediately available solution: full compatibility with HVO – Hydrotreated Vegetable Oil.

What is HVO?

HVO is a next-generation biofuel made from waste and residual fats through a hydrotreatment process that removes impurities and delivers a clean, stable, high-performance fuel. It can be stored long-term (up to 10 years), is resistant to oxidation, prevents bacterial growth, and ensures superior combustion thanks to a high cetane number (70–90).

Up to 90% fewer emissions

Replacing conventional diesel with HVO can reduce greenhouse gas emissions by up to 90%, without compromising generator performance. This clean fuel is a key step toward climate neutrality – and it’s available now, with no changes required to existing equipment.

No modifications. No compromises.

All Rehlko diesel generators are certified to operate on HVO, including the KD Series. That means they can run on 100% HVO or on any blend of HVO and conventional diesel, directly in the fuel tank. No technical adjustments are needed, and maintenance requirements remain the same. Adopting HVO is fast, easy, and completely safe for already installed systems.

Real-world example: sustainability in action

At the PAR8 data center near Paris, Rehlko (formerly Kohler) partnered with Digital Realty to power the entire backup infrastructure using HVO. The generators provide up to 72 hours of full-capacity autonomy, supporting the facility’s sustainability goals – with no compromise on safety or performance.

Lowering the carbon footprint in production

Rehlko has implemented HVO not only for generator testing, but also as the sole fuel source for its manufacturing facilities and headquarters in France. Replacing over 325,000 liters of conventional diesel with HVO has reduced annual CO₂ emissions by 750 tons, cutting the carbon footprint of the entire industrial complex by 50%.

HVO – part of the circular economy

Produced entirely from waste, HVO supports the circular economy and reduces reliance on fossil resources. With global production capacity expanding – including in the US, Europe, and Asia – this renewable fuel is becoming increasingly accessible and cost-competitive.
