To respond to the climate crisis, low-carbon green growth technologies for carbon neutrality are being actively developed in all industrial sectors. Among them, PV has the highest portion and very important energy for achieving a carbon neutral scenario. According to the latest analysis by BNEF (Bloomberg New Energy Finance), the global new solar power installed capacity until 2023 is expected to be 413GW. Moreover, 727GW of solar power is expected to be installed until 2030. In land PV, however, there are many restrictions for installation such as countries with small land area and high latitudes. In addition, environmental damage would be occurred when PV plant install in forest. To overcome the disadvantage of land-based PV, Floating Photovoltaic (FPV) which installs PV on the water surface are good solution. Initial research of floating solar power began since 2009 with a small-scale 2.4 kW demonstration plant. Afterwards, a commercialization foundation was established through a 100kW demonstration plant, and as a result, the world's first 500kW floating PV with commercial power generation was installed at Hapcheon Dam in 2011 by Korea Water Resources Corporation(K-water). In this way, K-water has been conducting research with various models and technological developments of FPV in the field, such as the first commercialization of FPV, tracking FPV, cost reduction, O&M, annual power generation estimation and marine PV. Recently, there are two major aspects in FPV research. One of research is that improve power generation and the other are models that can be linked with other renewable energy sources such as hydropower and green hydrogen production as well as expanding FPV in order to achieve carbon neutrality. For improving power generation, optimal application of bifacial PV needs to be researched in FPV. For achieve carbon neutrality, moreover, green hydrogen production using FPV, research on efficient energy use through cross-operation of FPV and hydropower p |
