Joules Unlimited

Jo10450151_680657768650710_5470902751896477621_nules Unlimited has developed proprietary Helioculture process to produce fuels such as ethanol and other infrastructure compatible hydrocarbon-based fuels through photosynthetically active genetically highly modified organisms. It operates from Bedford, Massachusetts, USA and from The Hague, Netherlands. The company’s production operation is in Hobbs, New Mexico.

The Helioculture Process of Joules Unlimited for CO2-to-fuel Production

Joules unlimited’s  process known as ‘Helioculture’ uses proprietary organisms that are genetically modified in such a way that they act as catalyst in the presence of sunlight to directly synthesize specific molecules of alkanes, olefins and ethanol using brackish water, nutrients and carbon dioxide.

The process of fuel synthesis takes place in SolarConverter® array. It resembles solar panel, captures sunlight and contains all the necessary ingredients for fuel synthesis. Waste CO2 is supplied from CO2 emitting industry. It keeps the organisms in motion and maximizes their sunlight exposure time and thereby the rate of the photosynthesis. Under these conditions the CO2 gets consumed by organisms that in turn continuously produce and secrete the fuel into the liquid medium. After a few separation steps the fuel is stored.

The modules of the SolarConverter® array where the process occurs are flushed and reinoculated after weeks of continuous run. As per the information available in the company’s website the process is different from a typical algae based oil production process as the Helioculture process produces fuels with no biomass production and with no further requirement for refining.


The first commercial products of Joules Unlimited will be solar ethanol and solar diesel known as ‘Joule Sunflow®-E’ and Joule Sunflow®-D. Joule Unlimited targets 25,000 US gallons of solar ethanol or 15,000 US gallons of solar diesel per acre annually, for approximately $1.20/US gallon ($50/barrel).

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
