Hello,

Take a look at those papers:

Zhou, C., Doroodchi, E., & Moghtaderi, B. (2013). An in-depth assessment of hybrid solar–geothermal power generation. Energy conversion and management, 74, 88-101.

Ghasemi, H., Sheu, E., Tizzanini, A., Paci, M., & Mitsos, A. (2014). Hybrid solar–geothermal power generation: Optimal retrofitting. Applied energy, 131, 158-170.

Astolfi, M., Xodo, L., Romano, M. C., & Macchi, E. (2011). Technical and economical analysis of a solar–geothermal hybrid plant based on an Organic Rankine Cycle. Geothermics, 40(1), 58-68.

Manente, G., Field, R., DiPippo, R., Tester, J. W., Paci, M., & Rossi, N. (2011, January). Hybrid solar-geothermal power generation to increase the energy production from a binary geothermal plant. In ASME 2011 International Mechanical Engineering Congress and Exposition (pp. 109-119). American Society of Mechanical Engineers.

Some potential applications of such hybrids are mentioned in those papers. 

I hope it helps.

In my new book, I addressed the economics of different types of energy supplies where I distinguish between its value on a stand alone basis, and renewables' contribution to a mix supplies portfolio. The portfolio evaluation is based on firms operating under uncertain energy markets, where price, costs and volume volatilities are prominent features. Contrasting these approaches to NPV,
