Figure 1.1.17 The solar refinery as the conceptual contribution of chemistry by chemical energy conversion to the sustainable use of renewable energy. The upstream part (hydrogen generation) and the downstream parts need not to be colocalized in a practical realization. CSP stands for concentrated solar power. Green boxes indicate solar fuel products blue boxes stand for intermediate platform chemicals. The red arrows indicate flows of solar hydrogen to a storage and transport system for large-scale applications. The blue arrows show the major application lines for chemical production of solar fuels. The scheme also indicates the role of fertilizers from ammonia required in sustained use of biomass for energetic applications.

HAMPTON CORNEIL has been a senior advisor for Exxon Enterprises Inc., an affiliate responsible for developing diversification opportunities for Exxon. Since 1975, he has been concerned with opportunities in energy conversion and storage. As a part of this effort, he has conducted various studies concerned with future markets for hydrogen.
