Title: “Ocean Imagineer: Floating Art & Science Laboratory Produces Oysters and Green Hydrogen in North Point, Hong Kong”


The Ocean Imagineer is a floating art and science work. The outside appearance is an artwork that raises awareness about the fragility and importance of oyster reefs in Hong Kong. On the roof solar panels power a hydrogen generator that is the clean energy of the future; underwater, millions of oyster larvae are being produced to improve water quality.

More than half a century ago, North Point’s waterfront was a popular destination for families to enjoy swimming. The water was clean and thriving with marine life. Once the area was reclaimed and industrialised, this changed. Today, however, the idea of diving into North Point’s polluted waters for a swim may seem crazy to most people. If we ever want the water to be clean again, we need to restore biodiversity and learn to live with other species sustainably. As Hong Kong transitions into a post-industrial society, can we imagine ways to help recreate the conditions needed to sustain a vibrant marine ecosystem?

Imagine this: It’s a sunny morning in September 2021; you are walking along the water of the North Point Promenade visiting the “Via North Point” art exhibition. You see an organic shape floating on the water, the “Ocean Imagineer”. It looks like a giant oyster, the size of a small yacht! Its irregular shell contrasts with the delicate mother of pearl iridescent interior. You take a few steps down from the pier, get on a small boat and step on board. You discover a busy biological research and fabrication laboratory inside.Transparent tubes bubbling with thousands of oyster larvae destined to repopulate Hong Kong waters; electronic technology with flashing lights and busy wiring and young people in lab coats introducing young children and North Point residents to their marine microscopic neighbours. You learn that the platform is used to deploy marine robots, the rooftop is covered with solar panels and that part of the electricity is dedicated to produce hydrogen: the clean energy of the future in stainless steel tanks. You are experiencing the timeless sensation of what the life of an oyster might feel like and the excitement of taking part in building the future: the creative integration of biology and advanced technology.


The  “Ocean Imagineer” is a floating art and science educational installation exploring:

  1. Biodiversity & Water Quality: Which marine species can best clean Hong Kong waters?
  2. Solar and Hydrogen Offshore Production: How much solar and hydrogen energy can we produce?
  3. Design Research: How can the Ocean Imagineer benefit the local community by leveraging innovative IoT, blockchain and AI technologies?


Visitors will be able to engage with the Ocean Imagineer from land with several activities such as:

  • Biodiversity & Water Quality: conducting experiments and seeing demonstrations of “how marine animals help improve water quality” with the University of Hong Kong, The Swire Institute of Marine Science, The Nature Conservancy and archiREEF.
  • Solar and Hydrogen Offshore Production: “building your own mini hydrogen generator” hands-on workshop with MakerBay Foundation team, supported by Safecast and Seeed Studio.
  • Design Research: exploring how to leverage IoT, blockchain and artificial intelligence to benefit the community with The National Conservatory of Arts and Crafts Paris and Scoutbots in partnership with Hong Kong Maritime Museum, Amber Initiative and Oasis Labs

Dates and locations of workshops and events will be posted on the Ocean Imagineer website (but may change subject to COVID19 and extreme weather/typhoon protocols).

Further Information

Biodiversity & Water Quality

Oyster culture has been practiced in Hong Kong for around 200 years. But some research shows that it has been a part of Hong Kong culture for 700 years. But the industry is facing many challenges, one of them being that there are only about 100 oyster growers left in Lau Fau Shan, compared to the 700 oyster farmers during the 60s and 70s.

The Ocean Imagineer is Hong Kong's first oyster hatchery.

“Hong Kong was once home to thriving shellfish reefs but due to a combination of factors including over-exploitation, coastal reclamation and pollution, shellfish populations have declined drastically. [...] "Globally, we have lost 85% of shellfish reefs, making it the most endangered marine habitat on earth," said Marine Thomas, Conservation Project Manager, for TNC in Hong Kong. "Most people associate oysters with food, but less well-known is that oysters create reef habitats that support coastal marine life. Only by restoring these lost habitats can we start to bring back some of the associated environmental benefits." [...] Healthy oyster reefs contribute to coastal environments in their role as natural water purifiers: A new study found that just 7 m2 of Hong Kong oyster reef can filter up to one Olympic sized swimming pool of water each day and a single Hong Kong oyster (Crassostrea Hongkongensis) can filter up to 30 liters of water per hour at summer temperatures. This is among the highest filtration rates recorded of any oyster species. Even more importantly, oyster reefs provide a habitat and nursery grounds for many native species that are otherwise lost from our shores. Another recent SWIMS study with Dr. Bayden D Russell conducted in partnership with TNC found that these reefs house six times more species than bare muddy shores [...]” Full article.

"The oyster is named after Hong Kong, so we should take care of this business and we should provide a solution for the sustainable development of this (700 years old) industry for new generations of (oyster) farmers," said Dr. Thiyagarajan. "We slowly need to change the psychology of our local population towards the consumption of these oysters." Full article.

“Oysters are a friendly alternative if you want to eat protein and not contribute to the greenhouse gas footprint.” Dr. Robinson Fulweiler

The Victoria Harbour’s water quality has also been upgraded significantly through the implementation of the Harbour Area Treatment Scheme. However the E. coli level is around 300 counts per 100mL and the level of dissolved inorganic nitrogen is 0.35 per mL. In comparison, in Deep Bay where Hong Kong’s oyster farms are located, the level of E. coli is 132 counts per 100mL and the level of dissolved inorganic nitrogen is 1.2 per mL. This shows that oysters help clean and add nutrients to the water in Deep Bay!

In the lab we will conduct research to help us better understand how oysters can help our shorelines from rising sea levels caused by global warming. We will also research hydrogen and test if it can power the plans of the future.

Design Research

The Ocean Imagineer is Hong Kong's first offshore solar hydrogen production plant pilot.

Hong Kong has vowed to become carbon neutral by 2050 and so did China by 2060. CLP has plans to invest in offshore hydrogen within the next decade, and “China Carbonomics cost curve highlights three key interconnected scalable technologies for net zero with 1) Wind and solar power 2) Clean Hydrogen is the second most important technology, potentially driving 20% of the de-carbonization of China's  Clean tech revolution. 3) Third, Carbon Capture technologies.” Goldman Sachs Report.

Economic development and environmental protection are often put at odds, as if it is impossible to make money while protecting the environment. What if oyster farmers can contribute to cleaning Hong Kong’s waters, help increase marine biodiversity and diversify their revenue streams with solar energy and green hydrogen carbon credits?


The Ocean Imagineer is an art and science installation that offers a glimpse of the integration of native species biologies, cutting-edge renewable energy research with the traditional sea farming community.

Educational workshops and tours will be announced on the website and via social media.
