In the Tenth Five-Year Plan, the Ministry of Science and Technology, proceeding
from the integrated system of planting resources and energy, selected fine fuel oil
plants suitable for different regions, and development base of fuel oil plant planting
resources and the demonstration project of biofuel oil production were established.
Genetic engineering and other modern techniques were used to improve species
characters and to cultivate new plant varieties with high fuel oil production. The
experiment of introducing, domesticating, and small area cultivation of foreign oil
plant species and fine clones with an important economic value has been carried out
through the demonstration of excellent provenance and rapid high yield cultivation
of clones [20–22].
3.1.2 Challenges in the Development of Biodiesel
(1) Domestic biodiesel has some shortcomings, such as small production scale,
backward technology, bad follow-up development, and so on.
The cost of biodiesel production is high because there is no tax exemption on biodiesel
in China (75% of which is the cost of feedstock), about three times as much as mineral
diesel, making it difficult to achieve mass production. At present, scientific research
institutes and enterprises mainly focus on the production technology of biodiesel.
(2) The production of biodiesel is relatively small, and the condition of using
biodiesel as pure fuel is not yet met.
At present, the average oil content and yield per unit yield of soybean and rape in
China are lower than the world average, which makes the production of vegetable oil
in China have a certain potential, but its development is still limited, even though the
oil content and yield level of oil plant is completely up to the international high level.
As estimated, this will still be difficult to make up for the current huge gap in food
consumption. It is difficult to achieve the development of biodiesel by expanding the
planting area of oil crops.
(3) The cost of feedstock
The main problem in large-scale production of biodiesel is the cost of raw materials.
About 75% of the cost of biodiesel production is the raw materials, and the choice
of feedstock route is very important to the competitiveness of biodiesel. Although
the raw materials for the production of biodiesel in China come from rapeseed oil,
cottonseed oil, Chinese tallow oil, wood oil, tea oil and gutter oil, and so on, but the
supplement of raw materials in the future will be mainly non-grain.
