In biofuel production majority of the costs include the procurement of raw materials. Hydrogenation, as compared to enzymatic hydrolysis, may offer more feedstock flexibility and reduced production costs. Crude palm oils (CPO), palm fatty acid distillates (PFAD), and animal fat high in free fatty acids are all less expensive feedstock (FFA). Hydrogenation is in the presentation stage in terms of development. Understanding hydrogenation catalysts is one of the most important topics for advancement. Subsequent generations of biofuels, such as algae-derived oils, are still in the applied research and development stage and will take a long time to become affordable. Renewable energy deployment requires the involvement of oil refineries and firms. There is also a concerning risk of hydrogen catalyst degradation, which can cause technical hazards.

The biodiesel development process, chemical reactions, and storage involve the blending of complex and conventional technologies. They're made in separate reactors with specialized hydrotreating equipment that create biodiesel that may then be combined with regular diesel from oil refineries or in co-processing plants. Founder plants utilize existing traditional oil refineries' hydrotreating capability to generate a single, blended diesel output. This lowers the hydrogenation plant's capital expenditures, but it also lowers the refinery's output of petroleum-based fuel.

Most of today's biorefineries focus on producing cleaner energy for automobiles. Despite this, many contemporary and new biorefineries have the capability to deliver a combination of SAF and sustainable diesel. Producers are likely to optimize their operations for increased SAF output as the need for SAF develops, fueled by governmental support and the industry's aim to reduce carbon emissions.

Several governments are also supporting biofuel production by facilitating consumers with subsidies and manufacturers with various benefits in the manufacturing and procurement processes. Biofuels became a viable source of energy as a result of the subsidy program, influencing mixing standards for conventional gasoline and consequently altering fossil fuel prices.
