What are multi-energy hybrid power systems using solar energy?

The multi-energy hybrid power systems using solar energy can be generally grouped in three categories. The first category is the hybrid complement of solar and fossil energies, including solar-coal, solar-oil and solar-natural gas hybrid systems.

How to improve the cycle efficiency of solar-geothermal energy hybrid systems?

For solar-geothermal energy hybrid systems, increasing the cycle efficiency of hybrid system is one of the most important future study works. Studies on the design of commercial-scale solar and geothermal energy hybrid systems are necessary. More research works on hybrid systems using S–CO 2 Brayton cycle are also meaningful.

What are the different types of solar power generation?

There are mainly two methods of solar power generation, which are solar PV [, , ] and solar thermal power generations [8, 9]. The PV power system converts solar energy directly into electricity by solar cells.

Are solar-biomass energy and solar-geothermal energy hybrid systems effective?

Solar-biomass energy and solar-geothermal energy hybrid systems can achieve 100 % renewable energy utilizations. Solar and wind energies can achieve a relatively good complementary relationship in time, and solar-wind energy hybrid systems can effectively solve the problem of power supply in remote areas.

Is a hybrid solar-gas power and hydrogen-production system feasible?

Wang et al. proposed a hybrid solar-gas power and hydrogen-production system. The system consisted of PTCS, GTCC system and hydrogen production system based on organic Rankine cycle (ORC), which is shown in Fig. 17. The economic and environmental protection analyses were conducted to reveal the feasibility of that hybrid system.

Can a solar and geothermal hybrid power system increase energy production?

Song et al. carried out a thermo-economic estimate of a solar and geothermal hybrid power system combining S–CO 2 cycle and ORC, and compared four different system structures. The results indicate that compared with the single S–CO 2 power system, the hybrid systems could rise the electric energy production by 22 %∼45 %.
