Singapore is exploring a hybrid system of wind, solar, tidal and wave power

Singapore has a lot of people but little land available for solar panels and wind turbines. However, there is plenty of open ocean to the south in the Singapore Strait. What it wants is renewable energy to power its economy reliably, consistently and reliably.

A collaboration between Keppel Infrastructure, National University of Singapore and Nanyang Technological University will conduct a study to determine if these waters can be used to create a hybrid renewable energy system for Singapore that combines offshore wind, solar floating, tidal and wave-powered. If the concept is deemed feasible, the three organizations plan to design and deploy a pilot system of at least 100 MW of renewable energy capacity that can be expanded in the future. After successfully implementing the new system in Singapore, the aim is to roll out the innovation to other parts of Asia and beyond, according to a report published in the Straits time.

All of the above for Singapore

The system would consist of modular floating solar platforms with the flexibility to integrate other renewable energy technologies such as ocean wave energy conversion systems, tidal energy turbines and paddles, as well than wind turbines.

The study will explore an offshore test site in the waters around Singapore. By utilizing these complementary energy systems, continuous power output can be provided around the clock while reducing the amount of marine space required for operations, the three parties said.

Cindy Lim, Managing Director of Keppel Infrastructure, said: “With limited land space in Singapore, moving into offshore waters provides opportunities to unlock the potential of more diverse renewable energy sources.” This would enhance energy security and support Singapore’s transition to a greener energy mix, she added. The MoU for the study was signed on Thursday during the Asia Clean Energy Summit 2022, part of Singapore International Energy Week held at Marina Bay Sands.

Keppel Infrastructure said the partnership will leverage its expertise in developing and operating efficient and reliable energy and environmental infrastructure, power retailing, as well as developing end-to-end low-carbon solutions. end, including renewable energy systems.

The NUS Solar Energy Research Institute and the NTU Energy Research Institute will provide expertise in areas such as pontoon-based floating solar structure and its integration with other energy systems. renewable ocean energy, as well as how to overcome the challenges of high winds. and wave forces on the mooring and anchoring system.

Prof. Madhavi Srinivasan, Executive Director of the NTU Institute, said the deployment of the renewable energy system in offshore conditions will face challenges such as buildup of microorganisms on submerged structures and corrosion. “We have unique expertise and the necessary experience that will be essential in solving such problems,” she said.

Takeaway meals

Every nation and city in the world has its own typography and cultural expectations. What works in the plains of Spain may not work in Singapore, Sumatra or Saskatoon. We’ve written about wave and tidal power systems, which have yet to achieve the kind of efficiency in power generation that could make them attractive to a wide range of potential customers. But no one knows Singapore like Singaporeans. If this triumvirate succeeds in delivering reliable renewable energy to the island nation, the “all of the above” approach to clean energy could win a new audience.
