Floating photovoltaic (PV) farms can be constructed in coastal marine conditions for the abundant ocean space compared to reservoirs. New challenges may arise when extending existing designs of reservoir floating PV regions because complex environmental conditions, especially pontoon type systems. This study presents methodologies design and verification such based on practical example one world's largest nearshore off Woodlands Singapore. 5 MW pilot project aims move from inland water future larger-scale deployments. The innovative system is adapted successful modular development at Tengeh Reservoir improved withstand harsher conditions. comprehensively introduces various aspects farm, including its design, via full-scale experimental testing numerical studies, construction, power generation performances. comprises standardized modules made high-density polyethylene (HDPE) that support panels or operational maintenance work. A compliant allows follow wave motion. was conducted through tests simulations a representative subsystem focusing hydrodynamic performance. Finally, this discuss on-site energy production serve as reference developing large-scale

Decarbonization potential of floating solar photovoltaics on lakes worldwide

Nature Water, Год журнала: 2024, Номер 2(6), С. 566 - 576

Опубликована: Июнь 4, 2024

Abstract As climate change progresses, there is increasing emphasis on net zero and energy system decarbonization. Several technologies are contributing to this agenda, but among these, the growth of solar photovoltaics has consistently exceeded all projections. With land-use pressures, expense building-mounted photovoltaics, water surfaces increasingly being exploited host these technologies. However, date, we lack an understanding global potential floating and, as such, do not yet have sufficient insight inform decisions (in)appropriate areas for future deployment. Here quantify generation over 1 million bodies worldwide (14,906 TWh). Our analysis suggests that with a conservative 10% surface area coverage, could produce contribute considerable fraction (16%, average) electricity demand some countries, thus playing important role in decarbonizing national economies.

Evaporation reduction and energy generation potential using floating photovoltaic power plants on the Aswan High Dam Reservoir

Hydrological Sciences Journal, Год журнала: 2024, Номер 69(6), С. 709 - 720

Опубликована: Март 26, 2024

An opportunity for efficient implementation of floating photovoltaics can be the coupling with other renewable energies, such as hydropower. The resulting synergies contribute to benefit both technologies. Particularly in arid regions, hydropower reservoirs face considerable evaporation. As a benefit, FPV minimises evaporation while simultaneously generating energy. In this study, we simulate reduction due by applying hydrodynamic General Lake Model together yield simulation model Zenit Aswan High Dam Reservoir. We estimate 49.7% at 90% occupancy and water savings up 5.9 billion cubic meters per year. mean specific saving system is 7.67 m3 a−1 kWp−1. analyse possible ways use saved water, additional hydropower, filling Toshka Lakes, or agricultural irrigation. irrigation appeared most efficient.

The development of fishery-photovoltaic complementary industry and the studies on its environmental, ecological and economic effects in China: A review

Energy Nexus, Год журнала: 2024, Номер 15, С. 100316 - 100316

Опубликована: Июль 3, 2024

The fishery-photovoltaic complementary industry is an emerging industrial model in China that integrates aquaculture with the solar industry. This innovative involves conducting activities while installing photovoltaic modules on water surface to harness energy for electricity generation. However, despite its rapid growth China, this lacks substantial scientific data support across various domains. Therefore, based analysis of relevant research literature, study reviews current development status, environmental and economic effects, as well challenges faced by China. aim provide references promoting sustainable within sector. findings reveal existing projects are primarily concentrated middle lower reaches Yangtze River Pearl Basin. geographical distribution these predominantly influenced local areas available resources, a greater impact observed from former rather than latter. During summer months when shaded panels, slight decrease average quality parameters cases was observed, such 0.2 units pH, 1.06 °C temperature, dissolved oxygen levels 0.8 mg/L, inorganic nitrogen content total phosphorus concentration dropped 0.08 mg/L 0.02 respectively. Conversely, there moderate increase noted ammonia levels. conclusion effect phytoplankton biomass not uniform, but it will certainly reduce zooplankton biomass. species diversity community minimal, direction, whether positive or negative, varied depending specific aquatic ecosystem. A certain degree shade advantageous cultivation shade-loving fish. Through strategic deployment panels implementation stocking practices, possible achieve sustained fisheries production. also can 978.6 tons CO2 emissions per megawatt year through production, thus achieving combined goals conservation reduction, ensuring profitability power Additionally, compared land utilization area 3.66 hm2 traditional ground-mounted photovoltaics, only requires 1.64 hm2, which significantly save resources utilizing surfaces, mitigates conflict between use agriculture renewable installations. At same time, pointed out existence inevitably have some negative impacts bird communities. Economic analyses indicate initial infrastructure costs long payback periods pose challenges, overall feasibility promising, especially governmental technological advancements. several need be addressed further development: include difficulties associated construction costs, periods; insufficient experience technical support; lack ecological - particularly urgent comprehensive life cycle assessments encompassing both aspects. Future should focus assessments, improved PV technology integration, optimized practices.
