Solar Energy, Liquefied

Joule Sunflow-E

Joule’s CO2-to-liquids platform can be tailored to produce multiple products via the same efficient process, simply by selecting the catalyst. Each of our catalysts is engineered to convert CO2 to a specific molecule of interest, including ethanol and hydrocarbons that comprise diesel, jet fuel and gasoline. 

Our first commercial products will include Joule Sunflow®-E, solar-derived ethanol, and Joule Sunflow®-D, the world’s first hydrocarbon diesel fuel produced directly from sunlight and waste CO2. We have also demonstrated the capability to produce a number of valuable chemicals that are typically derived from petroleum.

Our Sunflow products feature numerous advantages over their traditional counterparts, including the following examples.

Joule Sunflow-E

  • Requires only waste CO2, sunlight and non-potable water
  • Produced in a single-step conversion, with no downstream processing
  • Available in high volumes at competitive costs, targeting 25,000 gal/acre/year at approximately $1.28 per gallon
  • Requires no depletion of agricultural land, fresh water or crops

Conventional Ethanol

  • Requires biomass feedstocks that fluctuate in price and availability
  • Produced in a multi-step conversion, including biomass growth, collection and processing
  • Productivities are limited (200 gal/acre/year for corn ethanol and 2,000 gal/acre/year for cellulosic ethanol)
  • Requires use of agricultural land and, in some cases, food crops

Joule Sunflow-D

  • Requires only waste CO2, sunlight and non-potable water
  • Produced in a single-step conversion, with no downstream refining
  • Achieves stable supply and costs, targeting 15,000 gal/acre/year at $50-60 per barrel
  • Free of sulfur and aromatics

Conventional Diesel

  • Requires costly and diminishing petroleum
  • Produced in a multi-step process that is dependent on high-risk, high-cost exploration and extraction
  • Hampered by volatility of petroleum supply and costs
  • Requires added production costs to reduce sulfur content in line with government mandates
