Using Alternative Energy Extracted From the Oceans

[Dominick Penny]

The OTEC association, standing for the conversion of ocean thermal
energy, was founded by French engineer called Jacques D'Arsonval back
in 1881. The only remaining plant that is still a member of the OTEC
is based in Hawaii and represented a natural energy laboratory. OTEC
represents a source that can produce alternative energy which is
currently, however, underrated and unexploited. The thing that stands
in the way of the popularization of the OTEC is that it costs too much
at this point for many to afford it. It is thus difficult, to keep
costs down to some level because processes affected the OTEC,
rendering inefficient. Thermal energy derived from the ocean needs to
be cleansed and treated of any remains and then it can be utilized in
the air. It is also fairly important that the water coming from the
oceans is not polluted, since otherwise, you would risk to fail
completely in the transformation. Therefore, one needs to pay careful
attention when utilizing the OTEC at any point.
To begin with, you should know that there are three types of OTEC.
The first one is Closed Cycle OTEC which uses a liquid with low
boiling points; one such liquid is propane which is an intermediate
fluid. OTEC plants pump water which is warm into reaction chambers
which boil the water and use the intermediate fluid you have already
chosen. This means that the vapor pushes the turbine into the engine
and generates electricity. As a consequence, the vapor is cooled and
then is used into cold water coming from the sea.
The second types is the Open Cycle OTEC, which does not differ from
the closed method to a large extent. In here, you use no intermediate
fluid and you use the sea water to drive the engine across. In this
format, the sea water that is located on the surface ocean becomes
transformed in low pressure vapors, under the action of a vacuum.
Then, the vapor that was produced, which is , keep in mind, low
pressure, is released in another container and it thus located in that
it is capable to power the turbine. Then, you need to cool the vapor
and also, to produce water with no remnants of salt from the ocean in
it. After you do that, the water coming from the deeper parts of the
ocean will be added to vapors, and then it becomes capable to generate
electricity.
The last technique is called "Hybrid Cycle", but this technique is for
the moment, not implemented. It describes an optimal approach you
could use thermal energy at the maximum from the waters of the ocean.
There exist two theories concerning the hybrid cycling. As a
consequence, the first means using the closed cycling operation to
generate electricity. Thus, the amount of electricity is then used to
establish the cleaning environment that you will need for open
cycling. Therefore, the electricity that you produce this way will be
used to integrate the open cycling together. You then produce double
the amount of water that was desalinated.
Besides the fact of using OTEC to produce electricity, the plant with
OTEC has a closed cycle, which can be utilized to treat chemicals. The
OTEC plants, are capable of pumping cold water coming from the sea and
then use it for further purposes : refrigeration or air conditioning.
While under moderation in which the sea water surrounds the plant,
what you obtain from the process can be reused in aquaculture crops,
for instance in fish farming.
If you know how to exploit the opportunities you have, you will find
that there are numerous uses to the services and the products derived
from this alternative to energy production.
