Solar Fuel Generators
Science and Innovation to change our future energy option
Prepared by:
Sanat VarasadaFlorida Polytechnic University
Introduction
 A solar fuel is a fuel produced from sunlight through artificial photosynthesis or photo
electrochemical (PEC) cell.
 A solar fuel can be produced and stored for later usage, when sunlight is not available, making it
an alternative to fossil fuels.
 This technology producing two very important types of fuels:
# hydrogen
# carbon-based fuels
Production and use of solar fuels
• sunlight is used to split water into hydrogen and
oxygen.
• hydrogen can be used as a transport fuel, and is
also an important feedstock for industry.
• sunlight is also used to produce carbon-based fuels
from water and carbon dioxide.
• Carbon-based fuels such as methane and carbon
monoxide are key feedstock for making a wide
range of industrial products including fertilizer,
pharmaceuticals, plastic etc.
Pros and Cons
 Pros
i. Clean-burning fuel: Hydrogen is non-toxic, where
as coal, fossil fuels, and other energy sources create
greenhouse gases.
ii. Readily Available: Hydrogen is the most abundant
element in the universe
iii. Renewable: hydrogen reverts back to water when
it burns.
 Cons
i. Storage: Hydrogen’s energy content by volume is
low. This makes storing hydrogen a challenge because it
requires high pressures and low temperatures.
ii. Expensive: Cost of fuel & transportation is high.
iii. Low density of fuel, compared to gasoline
