Renewable Transportation Fuels are Needed
 Large‐scale renewable ground transportation fuels are needed
 Battery electric vehicles (BEV) use current electric utility power supplies
 Current electric utility power supplies are primarily fossil fuel‐based
 Hydrogen for fuel cell electric vehicles (FCEVs) is primarily from natural gas
 Large‐scale renewable air transportation fuels are needed
 Commercial air transport with battery power is impractical
 Commercial air transport with hydrogen FCEV technology is impractical
 Joule is developing large‐scale renewable transportation fuels
 Renewable ethanol is being produced at demonstration‐plant scale today
 Renewable diesel/jet fuel is being produced in the lab today
 Both use a one step, continuous carbon dioxide‐to‐fuel sequence

Joule Summary
 Joule is the most advanced and most scalable carbon‐neutral source of energy
for the mobility sector
 Recycles CO2 emissions through biocatalyst to produce ethanol and diesel/jet fuels
 Also uses sunlight, non‐potable brackish water and non‐arable land
 Protects existing assets from carbon taxes and emission caps through emissions reuse
 Can benefit from incentives for advanced biofuels and low‐carbon fuel markets
 Utilizes existing infrastructure, logistics, and service station networks
 To date, the company has committed $200m to develop technology
 Proven field operations at demonstration‐plant facility in Hobbs, NM, USA
 Produced independently‐validated US and EU fuel‐grade ethanol and diesel/jet blend stock
 Currently rolling out the first phase of the industrialization process
 Joule is assembling a strong network
 A coalition of a few large, international industrial companies to join Audi as strategic partners
 All advancements support the industrialization process
 Commissioning of first commercial plant in 2019
 Targeting full‐scale commercial rollout in 2020

• Extremely amenable to genome engineering
• No nucleus, chloroplast or mitochondial
compartments
• Rapid metabolism and cell division
• Multiple CO2 concentrating mechanisms
• No photorespiration or energy dissipation at high CO2
• Can be engineered as a thermotolerant species for
thermal management
• No biofilm or fouling issues
• Many barriers to genome engineering
• Nucleus, chloroplast and mitochondria are separate
membrane‐bounded compartments
• Each compartment has distinct chromosomes
• Difficult to control the integration and segregation of
DNA
• Slow metabolism and cell division
• Mitochondria contribute to energy cost of metabolism
