  2. 2. Sunthetics milestones & history 2 R&D project at the Albi University, France in 2008-2012 (PROMES, RAPSODEE, SOLLAB) Innovation Award at KIC Germany conference “Chemical Fuels” in 2014 Technology evaluation at Vattenfall R&D and KTH, KIC-Innoenergy 2013
  3. 3. Parabolic through is the dominating CSP technology 3
  4. 4. Sunthetics business idea 4 Sunthetics shall offer CO2 recycling of Solar based synthetic liquid hydrocarbon fuel technology at lower cost than fossil fuel with highest solar fraction, to the worldwide market. The solar ”oil well” for our future of energy and climate!
  5. 5. Market potential 1 5 The market for solar fuels as SUNTHETIC’s S2L for transport, electricity or heating is amounting to >10 million barrels/day, that can be replaced by the S2L fuel. The market will also increase over the years when countries like China, India and many parts of Africa are developed to a western style of energy economy, thus increasing the world energy consumption further.
  6. 6. Sunthetics system
  7. 7. Sunthetics system
  8. 8. S2L efficiency parameters 8 1. The S2L technology operates by hybrid solar power (cogeneration) 2. Solar heat and electricity for the process is generated by the ”Tertiary concentrator” (PROMES in France states its probably the most efficient solar CSP device ever developed in history) 3. The S2L receiver ( fuel reactor ) operates in ”process integrated mode” where exothermic heat from the catalyst & solar thermal input assist the electrolysis endothermic energy consumption 4 Electrolysis is assisted by nanopulsed electric feed* in combination with high temperatures, thus avoiding the need for H2O conductance amplification (no KOH needed as in Alkaline electrolysis) 5 Waste heat recovery and media pressure reduction are covered by a high speed piston expander & water desalination (final process energy recuparation) *International Journal of Energy and Environment (IJEE), Volume 3, Issue 1, 2012, pp.129-136
  9. 9. Koncentrator simulation model 9
  10. 10. SUNTHETICS Tertiary heliostat Concentration solar collector is based on parabolic trough technology 10 Electricity from concentrated PV Methanol reactor in the receiver tube The output can be any hydrocarbon or other basic chemical (fertilizer or polymer)
  11. 11. CPV technology (shape of cell front arrange light distribution to Tertiary concentrator) 11 Different options of selective transparency beam shaping reflector has been designed. From experience a solid lens made by the cell encapsulation material have lowest transmittance losses (exactly same as a standard PV-module). The water cooler that was designed in 2002 have been tested in other projects. High solar flux are managed by a combination of back contact and secondary cell reflector. Cell Secondary reflector Primary lens and cell encapsulation Concentrator with reflective cell and water cooler assembly
  12. 12. SUNTHETICS Receiver tube 1 12 Absorber selective surface Electrical contact surface Electrolyser assembly Catalyst carrier tube The output can be any hydrocarbon or other basic chemical (fertilizer or polymer)
  13. 13. 13 SUNTHETICS Receiver tube 2 Pressure valve (release O2) Anode/Cathode contact Selective surface Contact surface between electrolyser cells Electrolyser cells Catalyst tube* Inconel tube *Cu/ZnO/Al03 based catalyst or similar CuZnO-based ternary catalysts
  14. 14. Receiver reactor cell 14 O2 H2O CO2 H2 CH3OH (or other) + - CO+CO2 Control: • Tracker • Voltage • Current • Temperature • Pressure internal • Diff through catalyst • O2 release rate • Back pressure (via expander) High voltage power supply in series and chemical reaction in parallel enable ample capacity and high efficiency. Synthesis reaction exothermic release are absorbed by the electrolysis cell. Thereby lowering power consumed from the PV-cell string, and increasing system efficiency.
  15. 15. Co-electrolysis 15 H2O side with high pressure capability Design (>250 bar) H2+CO side with reduced pressure loss • Cathode/Anode area adapted to actual work load and pressure (HP micro tubes) • H2O side adapted to enable ceramic or polymer electrolyte at elevated pressure • No damage to electrolyte as its mounted flexible in many short elements • Extremely low current losses due to the Z-shaped stack envelope design • Flexible output from electrolyzer enable direct syngas production A controlled share of CO2 can be injected at the H2O side to do Co-electrolysis to H2+CO+CO2.
  16. 16. 30 % solar to hydrocarbon efficiency 16 The output can be any hydrocarbon or other basic chemical (fertilizer or polymer)
  17. 17. 17 SUNTHETICS first CHx reactor prototypes Electrolysis cell and solar receiver (TTE) hydrocarbon reactor connected to Spectrophotometer analysis system. The receiver can operate at room temperature in the experimental setup, although high efficiency resides between 275-350C (large scale systems should operate in the higher temperatures of 300-350C).
  18. 18. S2L Economics 18 1. The S2L technology economy can be extrapolated from existing CSP based on parabolic trough. 2. The S2L receiver (fuel reactor) is +50 % more expensive than existing CSP receiver producing steam rather than methanol (but here its @ 85CR) 3 Solar electricity for the process is generated in a factor of 40 times less expensive (patented) compared to photovoltaic cells (1,9$/W* for standard PV are reduced down to 0,1$/W in the Sunthetics system) 4 Integrated chemical processes = recuperative electrolysis/synthesis (patented), reducing energy consumed by >-30% even before solar thermal input 5 Waste pressure recovery by steam expander (patented) cover majority of compression energy in CO2+H2O media feed system Cost estimation indicates fuel cost may be well below current $/barrel *USDE/NREL ”Historical, Recent, and Near-Term Projections 2015 Edition”
  19. 19. Sunthetics IP 19 (“the Larsson-Maston process” patent, and four other sub-parts patents) 5 patent families and >100 single patents in the portfilio (and growing)
