Damless hydropower technologies and equipments on the basis of semi-submerged and submerged hydro-turbines: Conclusions

The main negative factor limiting the development of large dammed hydroelectric power plants is a violation of the ecological balance of the environment, linked with the necessity to build large dams and create large reservoirs. Large territories suitable for living people and animals are flooded; the land suitable for cultivation is waterlogged. The natural spawning grounds become unachievable for saving and reproduction of fish populations. All these factors restrict the technical and economical hydrological potential of water runoff. The authority and public of developed countries relates with great precaution to construction of new hydropower structures and pay great attention to previous studies of the effects of such building onto the environment.

The construction of river damless hydropower stations with submerged and semi-submerged hydroturbines that use kinetic energy of water flow for production of electricity is a real alternative to the development of river dammed HPPs and permits to increase level of river runoff employment. The rational use of the semi-submerged and submerged hydro-turbines foresees their parallel work with the operating classic hydroelectric power stations and pumped-storage hydroelectric power stations.

When damless HPPs are used, the problems linked with farmland flooding, demolition or relocation of settlements disappears. In other words, construction of the damless hydroelectric power stations practically does not violate the ecological balance of the area.

The dammed water HPPs may be done of different sizes and powers. In most cases they are mobile. This permits their transportation onto big distances, if necessary, Damless hydropower plants give possibility to closer production of energy to consumers and this way to simplify electric networks.

As all hydroenergetic technologies the damless HPPs in some measure can regulate the load of electrical networks, seasonally and daily.

The building of damless riverbed hydropower plants is hindered by deficit of hydroresources, using of macroscopic elements of working body (water flows) at transformation of mechanical energy of water into electrical power, employing of massive hydro turbines; indirect action of macroscopic hydropower systems, necessity in several stages of energy transformation, and low level of the employment of installed capacity (about 30%).

The limitations and restrictions of macroscopic hydropower plants stimulated the search of new high effective, ecologically friendly alternative technologies and equipment of electrical energy production with the use of renewable water resources, especially based on the profound energetic processes occurring on the atomic and molecular levels in water, water solutions and other liquids, which could become a base for molecular power engineering.
