geothermal energy Flashcards
It is the heat energy captured and harnessed
from earth’s interior and can be harnessed from the earth’s natural heat through active and young inactive volcanoes.
geothermal energy
The heat from deep
inside the Earth is
used to produce
steam to generate
electricity.
geothermal power plant
It use the heat coming
from close to the
Earth’s surface to heat
water or provide heat
for buildings.
geothermal heat pumps
Two categories of Geothermal
Energy Applications:
direct and indirect use of geothermal energy
It uses a combination of
turbines, generators,
transformers, and standard
power operating equipment
to convert the Earth’s heat
into electricity efficiently.
geothermal power plant
Are essential for
converting the kinetic
energy of a moving fluid
(in this case, steam
produced from
geothermal heat) into
mechanical energy.
turbine
they transform
mechanical energy into
electrical energy. As the
turbine blades turn, they
rotate the generator’s
shaft within a magnetic
field
generator
they alter the
voltage levels of
electrical current.
Transformers
This category includes
various devices and
equipment necessary for
the safe and reliable
operation of the power
plant.
standard power operating equipment
different types of geothermal power plsnt
dry steam
flash steam
binary cycle power plants
It uses hydrothermal fluids such
as steam in the same form as it
comes from the ground.
Drills wells into the ground until
reaching a geothermal reservoir.
The high-temperature steam
(above 150°C) extracted from
the reservoir is directly
channeled to a turbine, which
drives a generator to produce
electrical energy.
dry steam power plant
It converts both hot water and
steam from geothermal
reservoirs into electricity.
Involves pumping hot water
under high pressure to the
surface.
The release of this high-pressure
water into a lower-pressure tank
causes some of it to “flash” into
steam.
This steam then powers a turbine
connected to a generator
flash steam
It generates electricity by
indirectly using heat from
underground water.
Differs from the others by
not using steam directly.
Instead, it heats a separate
fluid with a lower
boiling point.
binary cycle power plant
Differs from the others by
not using steam directly.
Instead, it heats a separate
fluid what is the separate fluid
(like isopentane or
isobutane)
advantages of geothermal energy
Environmentally friendly
High reliability
Minimum land space
Economic viability
