Researchers from Politecnico di Milano have recognized floating photo voltaic photovoltaics (FPV) as a viable various to conventional hydropower in assembly Africa’s power targets, in response to a brand new research printed in Nature Vitality. The research reveals that FPV put in at present main reservoirs may generate 20-100% of the electrical energy projected from deliberate hydropower dams throughout Africa.
The analysis, carried out utilizing a complete power planning mannequin, reveals that FPV just isn’t solely cost-effective in comparison with different renewable assets but additionally performs an important function in Africa’s power future. “Floating photo voltaic has emerged as cost-competitive and will doubtlessly eradicate the necessity for a lot of new dams,” said Wyatt Arnold, the lead creator of the research.
An in depth evaluation of the transboundary Zambezi watercourse indicated that capital investments for brand new dams could possibly be extra successfully utilized by establishing fewer reservoirs and augmenting them with floating photo voltaic panels. This technique may lower interannual variability in electrical energy provide by 12% and improve resilience in opposition to long-term droughts exacerbated by local weather change.
“Adopting floating photo voltaic can present growing economies with a secure power provide much less prone to hydrological adjustments,” defined Prof. Andrea Castelletti. “Moreover, it mitigates antagonistic results on downstream communities and river ecosystems in comparison with new dam tasks.”
The research additionally underscores the importance of built-in useful resource planning and the necessity to take into account transboundary results in sustainable growth. It promotes multisector modeling that integrates power, agriculture, environmental safety, and financial progress inside river basins.
Prof. Matteo Giuliani famous, “The strategic deployment of floating photo voltaic would possibly outweigh potential drawbacks on reservoir makes use of like fishing or recreation. But, ongoing enhancements in FPV expertise and efficient planning are important for its accountable implementation.”
Whereas floating photo voltaic affords substantial environmental advantages, the research acknowledges challenges in expertise and social acceptance that will restrict its deployment. Nonetheless, these challenges are prone to be much less impactful than the unfavourable penalties of recent hydropower tasks, which might disrupt river ecologies, displace populations, and enhance regional conflicts over water use.
