Pongamia pinnata is also known as pongam or karanja or karanj. It is indigenous to India and Burma/Myanmar and is one of the few nitrogen fixing trees (NFTS) to produce seeds containing 30-40% oil. It is often planted as an ornamental and shade tree but is being considered as an alternative source for biodiesel.

Karanj is a major potential bioenergy crop in India.

  • India plans new biofuel mission, 11 April 2007 from Monstersandcritics.com. India is planning a new biofuel plan with a focus on jatropha and karanj. The first phase would cover 400,000 ha and the second 11.2 million ha of land. There are challenges to implementation, including the reluctance of farmers to invest in a crop like jatropha that doesn't yield seeds until the third year.
