HVO7 (or HEFA) is produced by hydrogenating vegetable oils, waste streams from food industry or
by-products of vegetable oil refining. The oils can originate from plants, algae or can be microbial oil.
Hydrogen demand for hydrogenation of different feedstock qualities varies, resulting in conversion
cost advantages for certain raw materials like palm oil and animal fats. In absence of technical
restraints, market forces and legislation are the main forces for raw material selection. HVO
production processes using plant oils such as palm oil have been heavily criticized as being
unsustainable. Our view is that HVO processes using plant oils can be sustainable, but clear
sustainability criteria are needed as a prerequisite.
