Description

Potential large-scale production of liquid hydrogen and liquid oxygen from water using photovoltaic solar energy conversion at the NASA Kennedy Space Center is examined in this paper. The example non-optimized, stand-alone facility described produces about 5.76 million pounds of liquid hydrogen per year, and 8 times that much liquid oxygen, which could support about 18 Space Shuttle launches per year.

A 100-MWp flat-plate photovoltaic array, neasuring 1.65 square miles, is required. The full array is made up of 249 modular 400-kWp arrays with several electrical/gas product "grids" considered. Hydrogen and oxygen are produced with either dispersed or central water electrolyzers. A central product liquefaction- facility with 2-weeks f storage is provided.

Estimated liquid hydrogen product costs, lewelized over a 20-year facility life, range few about $3.00 to $7.50/lb liquid hydrogen, depending Mainly on the cost of installed plioCovoltaics. (The range examined was $.50 t» f2/qp.) At about $l,50/Wp, a liquid hy- dngen eomrentional/non-f ossil cos t parity vnvld areem to be achievable over the period 1990 to 2010.
