Worldwide demand for petroleum is
increasing. Crude oil prices have topped
$135 per barrel. Oil prices have been on
a steady climb for a long time. Dwindling
OPEC oil reserves and a weak dollar are driving petroleum prices to new heights.
The
Exploding grain prices have exposed
the ethanol hoax and made poor people across the world scramble for food. Coal and oil sands are used to produce
petroleum substitutes and increase greenhouse gas emissions. The “Cap and Trade” concept was tried in
Electricity and liquid transportation
fuels are the lifeblood of our economies.
Economic growth is impossible without plentiful, affordable, and secure
energy supplies. Economies will collapse
when supplies of petroleum begin to shrink, when global warming keeps causing
damages, and when energy prices continue skyrocketing. Will our grandkids witness such disasters?
We are facing a problem that is too
large to be solved by industrial entities.
The financial risks of introducing new technologies are too large. Government agencies and industry cooperatives
must find technical solutions to our problems, must install a few of any new
energy producing installations, and must make the advanced technologies
economically competitive.
Are there any solutions that can be
developed before petroleum is depleted and before global warming exceeds the 3
to 4 degree Celsius global warming threshold?
The world community must solve these
two threatening disasters very quickly.
Petroleum reserves will last only a few more decades considering the accelerating,
worldwide demand. Greenhouse gases from coal
and petroleum combustion will continue to accumulate in our air at ever faster
rates and will accelerate global warming and ice melting. Any of these disasters may strike within less
than five decades.
Increased use of nuclear power can
generate large amounts of electricity and can replace the use of coal. Increased use of solar power, hydropower,
wind power, marine power, and geothermal heat can provide additional
electricity.
Surprisingly, only one single
concept seems to have the potential to produce sufficient amounts of liquid
transportation fuels. This concept is
the conversion of biomass into liquid petroleum substitutes.
The concept of biomass conversion
has just suffered a major public relations debacle. The ill conceived process of converting corn
by fermentation into ethanol has led to a temporary tripling of
Biomass conversion into fuel is our
one and only option. We must learn how
to convert sunlight, water, carbon dioxide, and fertilizer into biomass. Food crops are not suited for conversion. Food crops have been selected, domesticated,
and bred to provide tasty and nutritious foods.
Energy crops must be selected based on entirely different
properties. Energy crops must have very
high energy content, must provide very high crop yields, and must grow very
fast. This means that we must find and
further breed plants with very high energy yields; i.e. plants with the highest
values of energy per acre per year.
When designing biomass plantations,
we must address several specifications.
We need plenty of sunshine and we must protect against the
misappropriation and abuse of fertile lands and of forests. By locating biomass plantations on arid lands
and by combining biomass growing and biomass conversion into a single facility,
we can avoid abuse of agricultural lands.
Biomass production must be designed
to be highly automated and mechanized to lower costs. Additionally, biomass is best converted into
petroleum substitutes within hours. Such
quick conversion requires on-site processing.
Harvested biomass cannot be stored for long times. Liquefied petroleum substitutes can be stored
in tanks and can be transported by pipeline.
Obviously, such radical plantation concept,
which ideally uses hydroponic techniques and is not dependent on soil quality,
will need development. New biomass types
must be identified. The performance of
high energy yield plants must be optimized.
The engineering of hydroponic plantations located on arid lands or in
deserts must be completed, pilot plants must be built and tested, and fast
conversion processes for converting carbohydrates into hydrocarbons must be
found and developed to maturity.
One question remains; does our
Earth have large enough areas of arid land which are ideally located closely to
coasts and seawater?
In 2004 the world consumed roughly
30 billion barrels of petroleum. This
figure translates into an energy consumption of 173 exajoules per year. We know the energy yields of a few food
plants. We can extrapolate those energy
yields and arrive at a probable energy yield of newly bred plants of 10,000 gigajoules
per hectare per year. When we divide
energy consumption by energy yield we arrive at a figure of 17.3 million
hectare or 42.6 million acres. This area
is equal in size to the state of
