“Inexhaustible Sunshine”
Energy is Humankind’s Biggest Challenge!Three Existential Threats

Common man solution is needed now!Proposition: Affordable, scalable energy systems that are ready to go and can build pathways to harnessing Earth’s inexhaustible energy resource – SUNSHINE
A Viable Long-Term SolutionHarnessing, Storing & Distributing Sunshine

How could renewable energy, particularly solar and wind, be stored and shipped across
oceans and continents?
Sunshine is humankind’s vast inexhaustible clean energy resource 1 hour of Sunshine > 1 year of global energy needs

1G: Coal-based“High Carbon”
3G: Natural gas / Coal* + Renewable Power (ULE)
“Low Carbon”
4G: Natural gas / Coal +Biomass + Renewable Power
5G: CO2 + H2 from renewables“Carbon Neutral”
Technology Roadmap to Liquid SunshineFirst to Fifth Generation (G) Methanol Technology
2G: Natural gas-based
We are here TODAY!
*1G-Coal to methanol has higher CO2 emissions due to its higher carbon to hydrogen ratio. This can be mitigated by introducing a separate hydrogen-rich source into the process, thereby also improving the yield.
