Liquid biofuels: a pathway to sustainable energy

What are liquid biofuels?

Liquid biofuels are renewable alternatives to fossil fuels, produced from organic materials such as plant-based oils, waste fats, and agricultural residues. These fuels can significantly reduce greenhouse gas emissions and contribute to a more sustainable energy system. Common types of liquid biofuels include bioethanol, renewable diesel (HVO), and sustainable aviation fuel (SAF), all of which can be used in existing engines with little to no modification.

St1’s commitment to biofuel production

At St1, biofuel production is a key part of our strategy for reducing carbon emissions in transport and industry. The biorefinery, located next to the St1 Refinery in Gothenburg, has an annual production capacity of 200,000 tons of biofuels. This facility produces sustainable aviation fuel (SAF), renewable diesel (HVO), bio-naphtha, and bio-LPG, all certified according to the International Sustainability & Carbon Certification (ISCC) standard.

Flexible feedstocks for a sustainable future

Sourcing sustainable raw materials is essential for ensuring the long-term viability of biofuels. The St1 biorefinery is designed to process a variety of raw materials, including used cooking oil, fatty food waste and crude tall oil (CTO) fractions such as fatty acids - a by-product from kraft pulp production. To further secure supply chains, St1-owned Brocklesby Ltd, specialists in recycling food waste, has a crucial role in ensuring a reliable and sustainable feedstock supply.

Impact on emission reduction

By replacing fossil fuels with biofuels, the biorefinery contributes to a significant reduction in CO₂ emissions. The fuels produced at the facility are expected to lower emissions from road and air transport by approximately 500,000 tons of CO₂ annually compared to their fossil-based counterparts.

The future of biofuels: Biorefinery Östrand

St1 is developing Biorefinery Östrand, the world’s first large-scale biorefinery utilizing by-products from the Nordic forest industry and renewable power. This facility will have a production capacity exceeding 200,000 tons of biofuels and electrofuels. According to EU Innovation Fund calculations, it is expected to reduce CO₂ emissions by nine million tons in its first decade of operation, making a substantial contribution to global climate goals.

This groundbreaking project is a collaboration between SCA and St1, bringing together two strong companies in a joint venture.

Sustainable aviation fuel (SAF)

Sustainable aviation fuel (SAF) is produced from renewable raw materials, reducing net CO₂ emissions by ensuring that carbon released during combustion is part of a natural cycle. SAF can be blended with conventional jet fuel and is a key tool for reducing aviation sector’s carbon footprint.

Renewable diesel (HVO)

Renewable diesel (HVO) is a hydrotreated vegetable oil-based fuel that can reduce fossil greenhouse gas emissions by up to 90%. Chemically similar to fossil diesel, it works in conventional engines without modification, making it an immediate, practical solution for cutting emissions.

Bionaphtha

Bionaphtha is a HVO byproduct and offers a renewable solution as a blendable gasoline component and chemical industry raw material, which reduces directly emissions on use. It substitutes 100% the fossil comparison.

bio-LPG

As a byproduct of HVO production, we offer our bio-LPG as a solution on Autogas market and sustainable option for industrial LPG users. Bio-LPG can be used directly as 100% substitute for fossil LPG and it reduces the need for investments for reducing emissions.

Advancing sustainable fuel solutions

St1 continues to innovate in the biofuel sector, developing new production technologies and expanding the use of sustainable raw materials. By integrating biofuels into transport and industry, we contribute to the energy transition.
