OCC Finalist Spotlight – Meet Buogralon!

We are excited to introduce one of the finalists of the 2025 Ocean Community Challenge: Buogralon! 

This renewable energy startup from Hong Kong is developing a wave energy converter to harness ocean waves to generate renewable and zero-carbon electricity. In contrast to wind or solar energy, wave energy offers higher power density, is more predictable than wind, and is available 24/7 all year round.

Let’s dive into how this technology works! 🌊⚡♻️

The Buogralon wave energy converter (WEC) utilises a patented direct-mechanical drive power take-off (PTO) system instead of the traditional hydraulic PTO system. This innovative design results in higher energy conversion efficiency, lower production costs, adaptability to both low and high energy sea conditions, and is built to endure harsh marine environments.

The global wave energy potential is about 3 terawatts, while the global electricity consumption is ca. 3,3 terawatts (2023). Global wave energy potential could also almost cover all of the global energy demand. Thus, the wave energy market is projected to grow to US$34.41 billion in 2031. A huge opportunity for Buogralon, and we are confident that their unique engineering approach could give them a comparative advantage over similar wave energy start-ups.

Currently, the company is testing a 1:20 scale model in a test tank to validate their approach and collect data for the first sea testing, scheduled to happen in 2026 with a model in scale 1:7. The real scale model is supposed to be tested in 2027 with a target energy output of 500kW per device to provide a renewable alternative to generate clean, reliable, and sustainable energy for coastal economies. 

We are proud to support Buogralon and excited to join them on their mission to fight climate change by tapping into the huge potential of wave power for renewable energy production. 🌊
