Biofuels – Hot Attraction among Alternative Energy Patent Seekers
Published on 12 Mar, 2014
- The biofuel sector has attracted a considerable amount of research, with more than 2,500 patents filed every year since the past five years.
- Numerous experiments have been performed for production of various types of biofuels such as bioethanol, biodiesel, biogas, syngas, bioethers and the technology related to their efficient utilisation.
- It appears that research activity may increase in future due to the growing need of alternative energy sources to fulfil the energy demand among consumers and as a new diversion for economic growth.
Figure 1 depicts the filing trend for the past five years. As is clear from the filing trend, more or less equal number of patents was filed in this field of technology from 2008 to 2013.

Biofuels are derived from renewable materials such as waste plant and animal matters. Use of biofuels leads to emission of less greenhouse gases compared to fossil fuels; therefore, it is a neat alternative to conventional fossil fuels. Different types of biofuels are bioethanol, biodiesel, bioethers, biogas, syngas, and green diesel.
