1. Hydrogen Production  From “stranded” dedicated renewals (Wind in Aleutian Islands; Solar from North Africa; OTEC from Indian Ocean)  need 4 trillion KWH, per year for enough Hydrogen production  This equals 10 billion KWH per day or in round numbers 1 billion KWH per hour.  Figure of Merit is then 1 million Mega Watts (MW) of power needed for Hydrogen production  One Million MW = 1 TW  Is this a lot?

2. One Million Megawatts 1000 Nuclear Reactors (1000 MW each) 2000 Gas Fired Plants (500 MW each) Well if your going to build that crap, just connect it to the grid, you idiot Okay, then what about remote energy generation where grid connection is difficult

3. 1 TW Production Schemes  Harvest some Megaplumes Megaplumes  Build 100,000 10 MW Wind Turbines off the Aleutian Island Chain (note total wind resource here is about 50 TW) Aleutian Island ChainAleutian Island Chain  Place one 100 MW turbine every 200 meters in the Gulf Stream which is equivalent to a 200 km/hr wind

4. More Production Schemes  Distributed OTEC islands – circular platforms of radius 1 km can produce 1000 MW. (Russia wants to build floating nuclear power plants; Boeing wants floating equatorial launch platforms)  Note: 1 TW of PV power requires PV arrays (200 miles x 200 miles) in North Africa Desert

5. Bottom lines Large Scale hydrogen production schemes are possible using way out of the box large scale renewable energy systems where grid connection is unlikely Large Scale hydrogen production schemes are possible using way out of the box large scale renewable energy systems where grid connection is unlikely Solar Power is not a direct player in this scheme; CSP unlikely to work on this scale Solar Power is not a direct player in this scheme; CSP unlikely to work on this scale Many technical and financial difficulties exist but similar barriers were overcome in the last century!
