Instrumentation and gas analysis for renewable energy

< return to the range

Regardless of the energy sources: wind, geothermal, solar, biomass, the renewable energy industry is a fast-growing industry that is at the heart of global energy policies. To preserve the environment, each technological innovation requires efficient management of energy sources, using reliable gas analysis, and pressure measurement solutions.


Instruments de mesure et analyseurs de gaz pour l'industrie des énergies renouvelablesFuji Electric measuring instruments support professionals in the renewable energy industry during each phase of their production process in order to:

  • Lower the production costs,
  • Increase yields,
  • Extend the service life of installations,
  • Guarantee the quality of the finished product.


Renewable energies:

Hydroelectric power (pumped-storage power generation)

During the times when there is low electrical demand,  excess electricity is used to pump water from the lower  reservoir into the higher reservoir. When there is higher  demand, water is released back into the lower reservoir  through a turbine, thus generating electricity. The energy of falling water is used to rotate turbine and power generator, thus generating  electricity. Pumped-storage hydroelectric power is the largest-capacity renewable energy  in the world. It can provide stable power supply if the volume of water in reservoirs is  controlled.

Geothermal power

Flash steam system

Flash steam power plants pump up geothermal water from geothermal  reservoir through production well, and then separate steam from water. The steam is then used to operate turbine which generate electricity. The hot water is returned under the ground through re-injection well. This system is used when the temperature of geothermal water is high. The steam passed through a turbine is converted to hot water by condenser, and then cooled to be used in condenser.

Binary cycle system

Binary cycle power plants can generate electricity with low-temperature geothermal water because it uses a secondary fluid of which boiling point  is lower than water. Normal-pentane, fluorocarbon, hydrocarbon, or others are used as the secondary fluid. Fuji Electric proposes combining the flash steam system and the binary cycle system to enhance the thermal efficiency. A customer can add a binary cycle facility later on.

Wind power plants

Wind power is a clean source of energy, causing less environmental impact including  CO2 emission. However, it has significant variation in power generation, depending  on meteorological conditions. It is most popular among renewable energies although it has disadvantages such as: significant variation in power generation dependingon meteorological conditions; broad area requiredfor reliable powersupply; concerns about low-frequency sound  and wind noise. From the reasons above and others, large wind farms are often  constructed offshore.

Photovoltaic power plants

Solar power is another clean source of energy. The use of solar power is increasing  worldwide, especially in the form of domesticator commercial rooftop photovoltaic  panels. In some remote areas such as deserts, large-scale photovoltaic power plants are in operation.

Mechanism of solar cell

Photovoltaic power plantsWhen sunlight hit on a photovoltaic panel which is made of  P-type silicone and N-type silicone, a pair of electric charge,  positive and negative, is generated. Positive electric charges  gather in P-type silicone while negative charge in N-type  silicone, thereby generating electricity.

Biomass power

Biomass is a source of renewable energy, derives from organic matter such  as forest residues, sewage sludge, livestock waste, food residue. Biomass can be used as fuel in various forms, for example, solid fuel,  biogas, or bioethanol. Through combustion of these fuels, we can obtain  green energy.

Refuse Derived Fuel plants (RDF plants)

Refuse Derived Fuel (RDF) is also referred to as "solid recovered fuel", a fuel produced from waste from households or offices.
These wastes are dried, processed, and mixed with lime to be used as RDF in power plants.
Refuse Derived Fuel has advantages such as: easy to transport, suited to long-term storage, stable  quality, generates more heat compared to general waste.
