Hassabou PVT Solar Collector
Operation of PV systems under extremely high temperatures in hot climates and dust represent two of the major challenges for all PV applications. As the efficiency of PV cells drops significantly at high temperatures when the demand for cooling and water desalination, as major consumers of energy in hot arid climates, is also high, maintaining the temperature of PV modules at a lower level is highly desirable and offers two additional advantages: an increase of the life expectancy of PV modules and stabilization of the output power characteristics.
For more than six years, BIET has been developing an advanced patented solar technology that combines both solar PV and solar thermal (Concentrating Solar Power “CSP”), i.e. hybrid PVT, in one collector that eliminates all the problem related to both PV and CSP, as the two main streams of contemporary solar technologies.
The patented PV-T technology offers The technology is simple and neither needs tracking the sun nor evacuation of thermal absorbers, while it relies on hot water storage for storing thermal energy to drive low temperature steam or ORC turbines during nighttime. The overall efficiency of both electrical and thermal components is > 92% compared with <20% for conventional PV or standing alone CSP.
We have designed the PV-T system or “Hassabou Technology” to supply firm capacity and dispatch-able power on demand 24/7/365 with no batteries and no sophisticated molten salt thermal energy storage “TES”. The Hybrid (PV-T) Collector provides the highest conversion efficiency of a solar system globally, extend the life time of PV modules, and provides highest energy harvesting density per unit of land area with continuous operation day and night around the clock.
The Hassabou PV-T is integrated with Green Hydrogen to drive steam and combined cycle Power Plants . The PV-T + H2 captures at least 92% of the solar radiation using stationary PV-T collectors and stores it for use on demand, either regularly or for planned extended periods of grid demand based on a pressurized hot water storage up to 130 C and hydrogen storage to top up temperature up to 1850 C to drive combined cycle power plants.
Primary energy for conversion to electricity requires a 20-25% input of green Hydrogen produced on site using the electricity produced by the PV-T and an 75-80% input of solar thermal storage using a combination of a Brayton Cycle H2 turbine and a solar augmented Heat Recovery Rankine Cycle turbine. Thermal efficiency of up to 60% is further optimized using heat recovery economizers within the stored water based heat transfer fluid. The Plant generates Zero CO2 and recovers essentially all water used in its power generation cycle and Electrolysis Cycles that produce green hydrogen. Extended storage of up to 100 hours is possible.
Hassabou PV-T Solar Collector Patent
Abdelhakim Hassabou Ph.D. Chairman of BIET Group has disclosed the revolutionary hybrid PVT in 2014, as the sole inventor of this technology, with an International Patent Filing Application PCT/US17/15932 at the US Trade Office under Docket No. 32791.01 under the invention’s name “COMBINATION PHOTOVOLTAIC AND THERMAL ENERGY SYSTEM”.
Revolutionary Hybrid PV-Thermal (PV-T) Technology
Abdelhakim Hassabou Ph.D. Chairman of BIET Technologies Group emphasizes: Solar Renewal Energy is foreseen to be the most important clean resource that can be utilized into many applications and projects we are developing. We will soon launch an innovative hybrid solar Photovoltaic & Thermal energy collector (PV-T); “HASSABOU COLLECTOR” to generate power around the clock 24 hours per day with a simple hot water storage that eliminates all the hurdles associated with contemporary solar technologies both in Concentrating Solar Power (CSP) with molten salt thermal storage and PV with batteries. We are in advanced stages in developing the largest solar desalination plant in the world with a capacity of 300,000 m3/year. On the electrical power generation side, we will start with multiple power productions projects ranging from 50 MW to 120 MW in the USA and Caribbean using the innovative PV-T integrated with Green Hydrogen as well as other technologies developed by industry partners from the USA, Germany and Europe. BIET plans to establish industry complexes for the whole supply chain for mass production of the new technology in some countries starting from the USA, where the BIET’s headquarter is. A number of solar power, solar desalination plants, and green hydrogen will be installed in multiple countries in the next few years.
