Sea6 Energy: Seaweed to Ethanol

Sea6 Energy is a Bangaluru, India based startup attempting to produce ethanol from the fermentation of sugars extracted fro10450151_680657768650710_5470902751896477621_nm seaweed. It was formed in 2010 by Mr. Shrikumar Suryanarayan a professor at Indian Institute of Technology Madras. Sea6 Energy’s laboratory is located at the Centre for Cellular and Molecular Platforms (CCAMP), NCBS-TIFR, GKVK Campus, Bangalore, India. Department of Biotechnology, Government of India is one of the key investors in the venture.

Seaweed to ethanol

Traditionally seaweeds, also called macro-algae, are grown for speciality food products. Its potential as a biofuel feedstock lies in the fact that it grows on the surface of the sea while extracting nutrients from the flowing sea water. Seaweed biomass is rich in carbohydrates which can be converted in to sugars. But the fermentation of these sugars is a difficult task owing to their chemical composition which is significantly different than that of normal land plants and very few organisms are able to do so. Sea6 Energy has partnered with Novozymes to research  and produce enzymes to fasten up the seaweed carbohydrates to fermentable sugars conversion process.

The company has successfully developed a lab scale seaweed sugars fermentation process using normal yeast and with the use of minimal amount of fresh water resources. Sea6 Energy is also credited to have developed and patented off shore large scale seaweed production technology.

In addition to renewable energy the company is also focusing on developing other products from sea weeds for different sectors such as from sea weeds for food, pharmaceuticals, nutraceuticals and agri business.

Commercial Product of Sea6 Energy: Jingo

Sea6 Energy has also set up a ‘Sea Weed to Plant Growth Nutrient’ manufacturing plant of 400,000 litres per annum capacity at Tuticorin, a port city of Tamil Nadu.

The first commercial product of the company is going to be sold by Mahindra Agri Business, a Mahindra Group company under the brand ‘Jingo’. The price of the product is said to be Rs. 650 for a 750 ml bottle. By helping the root systems to proliferate and increasing the leaf index area Jingo is able to stimulate the growth of a variety of crops including paddy, wheat, cotton, sugarcane, vegetables, tea and soyabean.

Karnataka to get $50 million dollars for biofuel

In India the Karnataka States’ Biofuel Development Programme  is set to get a boost in the form of  $50 million dollars from International Fund for Agriculture Development (IFAD). The loan can be utilized in various activities such as plantation of biofuel crops and production. Biofuel Development Board of Karnataka has been active in promoting biofuels and  has established biofuel information and demonstration centres with about 100 l per day capacity in each district. These centres are being scaled up to 150-200 l capacity. The Board also owns a 500 litre biodiesel production plant at Hatti Gold Mines. The loan conditions include 1% interest with a 50-year repayment period.

China’s first commercial flight powered with biofuel was successfully completed

China's first commercial flight powered with biofuel was successfully completed between Shanghai and Beijing. The privately owned Hainan Airlines flight used biofuel made up from used cooking oil collected from the restaurants. The biofuel was supplied by China National Aviation fuel company and energy giant Sinopec. It was a Boeing 737 plane which used 50% biofuel blended in conventional jet fuel and carried more than 100 passengers to their destination.

India achieved only 1.4% ethanol blending this fiscal year

Problems between sugar mill owners and oil marketing companies have resulted in only 1.4% ethanol blending through february this fiscal year which is way less than the blending target of 5% and lesser than the last year's achieved blending level of 2%.The National Policy on Biofuels of India identifies the sugar cane molasses as the feedstock suitable under Indian conditions for ethanol production for blending purpose and that makes the sugarcane mills as the biggest suppliers of bioethanol. The high state-level levies on the biofuel and the requirement of obtaining permits from authorities have been sited as the major impediments for producing bioethanol by Sugar Mills. The government has set the selling price of ethanol for sugar mills @  Rs. 48.50/litre  if the depo of the oil marketing company is within 100 km from distillery and  @49.50/ litre  if the depo is beyond 300 km. The producers claim that the long distance transportation also reduces their margin. India needs approximately 115 crore litres of ethanol to meet the 5% target. Read more at
