Hanyang Technology develops new generator "Hailongwang"

The special feature of the new generator "Hailongwang" is to avoid the hydraulic mechanical thinking that traditional wave generators rely on, and use soft materials to make valves, so that the sea waves entering and leaving the water tank can push the pulp to rotate, regardless of whether the waves are high or low. Drive the power generation.

Soft but dripping, the merchant is inspired by the fishing rod and designed to be the first generator in the world to generate electricity in the calm sea.

The power system named "Dragon King of Ocean" (Drakoo) is developed by the Singapore clean energy company Hann-Ocean. Unlike the generators that use ocean waves, the system does not need to be complicated. Mechanical devices, smaller in size, can reduce costs.

The waves contain rich energy. Unlike solar energy, the waves have day and night, and the space occupied by wind power is small, so the development potential is not small.

The special feature of "Hailongwang" is to avoid the hydraulic mechanical thinking that traditional wave generators rely on, and use soft materials to make valves. When the waves are high, the high pressure outside forces the valve to open, and the seawater that enters the water tank pushes the pulp to rotate. In turn, the power generation is driven; when the waves are low, the higher pressure in the cabin forces the seawater to flow out, so that the double-blade still maintains one-way rotation, ensuring that the power is balanced.

The design of the valve was inspired by the fishing rod. The fish was closed when the fish opened its mouth and the fish was closed when the fish was closed.

Han Lei, the founder of Hanyang Technology, said: "The fishing rod is very soft, but it does not leak at all. The principle is simple, but no one thinks it can be applied to the generator."

Han Lei pointed out that because the generator has high sensitivity and the electric energy conversion rate is as high as 55%, it is suitable for small waves. The generator casing is also equipped with a two-layer grille that isolates the fish from the threat of marine life.

The generator is rectangular, 3 meters wide, 2.3 meters high and 2.3 meters deep. It can be assembled several times and connected to barges, docks and so on.

According to estimates, in terms of 100 kilowatts of electricity, the electricity generated by this system can be used for about 75 four-bedroom flats a year. On average, the cost per unit of electricity is lower than the current household electricity rate of 27 points per degree. .

Han Lei’s idea is to install the generator on the ship, “collect” the electricity to the place where the sea is going to wave, and even sell the electricity to the ship parked at sea.

Four "Sea Dragon Kings" have been sold

Jurong Shipyard, a subsidiary of Sembcorp Marine, has purchased four “Hailongwang” with Hanyang and plans to test the technology at the Tuas Integrated Shipyard under construction. This large new shipyard is expected next year. Opened in the second half.

Dr. Michael Abundo, a researcher at the Energy Research Institute of Nanyang Technological University (ERI@N), said that the waves are as windy as the wind and are as elusive as the wind, so it is not as predictable as solar energy, but the design of the "Sea Dragon King" Perhaps this problem can be overcome.

They plan to cooperate with Hanyang Science and Technology and start a half-year study from November to further explore the feasibility of wave power generation locally.

Hanyang Technology spent four years developing the system, and sent it to the UK for certification. It also applied for a patent. Han Lei believes that in addition to his own technical background, the subsidy given by SPRING is also very important. Hanyang Technology will showcase this technology at the Asia Future Energy Forum held at the end of this month. They are also working with British universities to develop another round of high-powered "Sea Dragon King", suitable for waves with more than two meters of high waves. Power generation on the sea.
