1 Artificial Photosynthesis JCAP Scientist: Joel Ager C2M Team: Ismael Ghozael Luc-Emmanuel Barreau Timothy Kelly Wesley Chen

2 JCAP project, support and funding 2 At the California Institute of technology, they re developing a way to turn sunlight and water into fuel for our cars President Obama, SOTU January 25 th, 2011 JCAP funding: $122 Million over 5 years July, 2010 JCAP formed Discovery of efficient and cheap materials Assembly of pieces into scalable system Increased efficiency; variety of fuel types

3 Artificial Photosynthesis Process 3 H2O O2 CO2 High Voltage PV absorber Integrated steps Electrolysis H2 Liquid Fuel Production Liquid fuels (Methanol) Invention (patent pending): Micro-integration of the photovoltaic absorber, the catalyst and water High efficiency, scalability. This technology is very early stage (<1 Year in). Many technical unknowns Cost target Daily production volume Purity

4 Value proposition 4 Integration: Higher efficiency and scalability Distributed & Modular Carbon neutral process Stable feedstock prices

5 Project approach 5 Products considered Rationale Hydrogen is produced by JCAP s prototype O2 Oxygen is produced by JCAP s prototype Methanol Methanol is the simplest credible fuel candidate to synthesize Goal: To determine target cost of products and market characteristics for artificial photosynthesis to be competitive in these existing markets

11 Hydrogen Target market selection 11 First target: Distributed H 2 Premium value (competing tech costs of 6.7$/kg) Modularity valuable to customers Limited / no switching costs Operational limitations of the technology Low pressure output Intermittent production (solar) => Need for storage

12 Additional Possible Product: O 2 12 Electrolysis: 9kg H 2 O -> 8kg O kg H 2. O 2 : 0.21$/kg (liquid), Premium H 2 : 6 $/kg H 2 value = 6$, O 2 value=1.6$. O 2 is a by-product. Market Hurdles? Decision Premium O 2 - Medical gas O 2 +H 2 Petroleum refining O 2 +H 2 Rocket fuel (NASA) - Purity - Regulatory: only electrolysis currently approved - Use of H 2 unclear: hospitals unwilling to operate small fuel cells - Competing with captive production - Usage is liquid H 2 and O 2. Liquefaction would be cost-prohibitive Go, go under conditions, no-go

13 Why Methanol? - Short technology path - Low manufacturing switching cost. - Regulatory environment is favorable - Credible fuel alternative Source 1 : energy.gov Source 2: ethanolrfa.org/pages/statistics#b

19 Methanol: Longer-term opportunity 19 Today the demand for methanol is happy with its supply, DOW Chemicals TRUE: The market is indeed in equilibrium BUT growth is strong, driven by the fuel market. This technology has the potential to accelerate this trend. The methanol industry is extremely efficient. To compete, the cost target for H 2 with artificial photosynthesis has to decrease to 2 $/Kg. Potential accelerating factors Decrease in the cost of Carbon capture. Carbon Tax Increased technology integration encompassing to the fuel generation.

28 Appendix - Why Methanol is a credible fuel! 28 The Open Fuel Standard First introduced in the U.S. Congress in 2009, the Open Fuel Standard Act would ensure the widespread adoption of alcohol-fuel compatible FFVs. These bills with slight variation in current House and Senate forms would require that at least 50% of the vehicles produced for the U.S. market that use an internal combustion engine (which would include plug-in hybrid vehicles) must be compatible with blends up to both M-85 and E-85 fuel by the year The same rule would apply each year until 2015, at which time 80% of vehicles produced for the U.S. must be fuelchoice enabling vehicles. The cost for these conversions would be about $50 - $150 per car, and at current prices, a driver would save more than that annually in fuel costs if they filled up with M-85 all year long. The unsubsidized cost of methanol on an energy party basis currently averages about 90% of the cost of regular unleaded fuel.

Variable cost of production Assumptions: -25 year useful life plant - Gas cost low US$1 MMBTU - Finance 70:30 debt/equity at 8% on 10 years

36 Appendix - Methanol Storage Cost 36 Storage costs are negotiable and vary depending on the product, tank size, special equipment required, mode of in and out bound shipments, contract terms, etc. In a broad sense, a public terminal company would charge a base rate per ton, per month for methanol stored in a 12,600 metric ton (100,000 barrel) tank on a year s contract. This base charge would include four tank capacity throughputs (50,400 mt/400,000 bbls) per year, and some extra incidental costs such as loading tank trucks and cars. Depending on customer/contract status, these terms are negotiable, particularly if more frequent throughputs are required. Four tank capacity throughputs per years (about a turn per quarter) are fairly standard. Storage costs per ton can be reduced significantly by increasing the number of throughputs per year.
