Project summary

The Project objectives are development of new high effective solar technology for production of high pure hydrogen and creation of autonomous solar installation for its realization. The new technology includes the concentration of solar radiation, the photo conversion of solar energy into electric one, high temperature steam electrolysis, purifying, compression and rapid hydride accumulation of obtained hydrogen.

It will be done:

To the project at whole - the new effective heliotechnology will be elaborated and the autonomous energy transforming installation for hydrogen production from steam, its purification, compressing and safe storage in improved hydrides and accumulators will be created.

To the high-temperature power installation - the new concentrator of the solar radiation of "Novikov's mirror " type will be created, its parameters will be calculated, the new methods of the calorimetry. The new helioreceiver in a form of the cavity model of the absolute black body will be elaborated.

To the photo-battery - the source of the photoelectric current with the system of the low solar radiation concentration as focussing conus (focons) and focussing wedge (fowedges), which will be provided with the device for the photo-elements cooling, will be created.

To the electrolyzer - the high-temperature electrolyzer of the steam of increased efficiency will be created.

To the hydrogen accumulation - the original framework hydride accumulator with the developed inside heat exchange surface on the basis of the powder hydrogen absorbents and the hydride accumulator on the basis of the metal matrix composite intermetallic absorbents of hydrogen with the improved heat exchange characteristics will be created.


The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.


ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
