Bioethanol plants are required by the government to sell their produced fuel ethanol only to appointed oil companies, such as PetroChina or Sinopec at a price of 0.91 or about $0.82/liter. The government subsidizes the gap between the sale price and production cost. China's potential marginal arable lands are limited and most are fragmented.
The process to be used at the Emmetsburg plant will enable the plant to make 11% more ethanol by weight of corn and 27% more by area of corn. The process cuts the need for fossil fuel power at the plant by 83% by using some of its own byproduct for power. The $200 million plant is scheduled to begin in February and take about 30 months to complete.
By 2009 two other sugarcane ethanol production projects were being developed in Kauai, Hawaii and Imperial Valley, California. The Hawaiian plant was projected to have a capacity of between 12–15 million US gallons (45 × 10 ^ 3 –57 × 10 ^ 3 m 3) a year and to supply local markets only, as shipping costs made competing in the continental ...
Sugarcane production in the United States occurs in Florida, Louisiana, Hawaii, and Texas. In prime growing regions, such as Hawaii, sugarcane can produce 20 kg for each square meter exposed to the sun. The first three plants to produce sugar cane-based ethanol are expected to go online in Louisiana by mid 2009.
The so-called "third-generation biofuels", similar to second-generation biofuels with an emphasize on the use of algae and cyanobacteria as a source of biofuel feedstocks, have an additional advantage as they take up a relatively small fraction of space when compared to first and second-generation biofuel sources, and may also help to reduce seawater eutrophication.
[46] [47] Because plants consume carbon dioxide as they grow, bioethanol has an overall lower carbon footprint than fossil fuels. [48] Substituting ethanol for oil can also reduce a country's dependence on oil imports. [49]
Biodiesel production is the process of producing the biofuel, biodiesel, through the chemical reactions of transesterification and esterification. [1] This process renders a product (chemistry) and by-products .
An operating lignocellulosic ethanol production plant is located in Canada, run by Iogen Corporation. [32] The demonstration-scale plant produces around 700,000 litres of bioethanol each year. A commercial plant is under construction. Many further lignocellulosic ethanol plants have been proposed in North America and around the world.
