Renewable Power

The current trend for “carbon free” energy has generated interest in exploitation of alternative energy sources. Thus, such renewable resources as geothermal, solar and ocean thermal are being considered for widespread development. Each of this technologies has needs in corrosion resistant or/and high temperature and/or high pressure tubes. NEOTISS provides a wide range of products matching the needs of these new technologies.


Geothermal power use steam produced from reservoirs of hot water found deep below the Earth’s surface to produce electricity. The steam rotates a turbine that activates a generator, which produces electricity.

Concentrating solar power (CSP)

CSP is a solar power generation technology also called thermodynamical solar energy. In this technology, mirrors are used to concentrate the sun’s rays in order to heat a working fluid and produces steam through heat exchangers. The steam drives a turbine and generates power in the same way as conventional plants.

Ocean thermal energy conversion (OTEC)

OTEC is also a power generation technology. A working fluid with low boiling point is vaporized using the ocean’s warm surface water. The vapor expands and spins a turbine coupled to a generator to produce electricity. The vapor is then cooled by seawater that has been pumped from the deeper ocean layer; That condenses the working fluid back into a liquid, so it can be resued.
