The ocean provides an abundant source of renewable energy, including wave energy. Hann-Ocean’s wave technology “Drakoo” can generate economic electricity from all scales of waves. Since 2008, the Drakoo has been developed and tested extensively in full-scale in the sea as well as in large-scale wave flumes including the independent Narec’s verification. With our first commercial pilot project (16kWp) delivered in 2013 and after four more years product optimisation, the latest Drakoo WEC is now ready to offer an affordable and sustainable power supply for the offshore industry, coastal developments and remote islands worldwide.

Hann-Ocean Energy is a wave technology developer from Singapore. In 2008, a Twin-Chamber Oscillating Water Column Wave Energy Converter (WEC) was invented by Henry Han Lei, the founder of Hann-Ocean. The wave technology was named ‘Drakoo’. Since then, our professional team has been conducting R&D on the proprietary Drakoo wave technology. It has been developed and tested in full-scale in the Singapore sea as well as in Narec’s and Hann-Ocean’s large-scale wave flumes for its performance, reliability and endurance tests. After 9-year development, the latest Drakoo Type-B WEC 10kWp module is now ready for order. We believe that the Drakoo is the most efficient and diversified WEC technology to date. It will set a brand-new technology standard that allows wave energy to meet growing global demand for clean energy.

Wave energy is a vast, untapped resource that could help reduce our reliance on fossil fuels. Like solar and wind power, wave power harnesses energy that comes ultimately from the sun. However, wave power is about ten times and 100 times denser than wind and solar energy respectively (depending on sea locations). Compared to solar and wind, waves are easy to forecast, and unlike solar, wave energy can be harnessed 24/7.

The ocean wave is the unexploited greatest potential renewable energy resource in the globe. International Energy Agencies projected the potential of global wave energy to be about 8,000-80,000 TWh per year, and typically 10-60 kW per meter along the coasts. The energy supply in the future will be a mix of multiple types of clean energy sources. The Australian Power Generation Research Institute predicted that wave power generation would account for about 20% of the total power generation by 2050.

The ocean wave is currently not a significant contributor to the total output of clean energy productions. Although various concepts exist, the majority suffers from a relatively low efficiency and is susceptible to breakdowns compared to other more mature clean energy technologies such as wind turbines and solar panels. However, the ocean wave is the unexploited greatest potential renewable energy resource because it is dense, predictable, persistent, and widely available along coastlines and in the deep oceans. To have wave energy widely, we need technology breakthroughs in the energy conversion, which has attracted worldwide research and development efforts. For the goal, Hann-Ocean is dedicated to the sustainable energy technology development.

Three key factors making the wave energy attractive and feasible:

1.

The wave energy flux in terms of kW/m represents the annual average wave power density for a specific sea location. The higher the wave energy flux, the denser the energy resource. Electricity demands of various locations near the coastlines set potentially usable electricity limits. Ideally, wave power production should be located as close as possible to the end-consumers to save the transmission costs and reduce the power loss.

2.

The energy demand and resource for small communities at coastal areas, on remote islands or offshore platforms, make us believe that they will benefit the most from ocean renewable energy generation, especially for those who pay a premium on electricity prices for diesel transport and diesel power generation.

3.

The political factors in the selected areas heavily influence the prospective returns of investments in ocean renewable energy project developments. As a response to the world climate change, many governments have established renewable energy development incentives including grants and feed-in tariffs to promote and accelerate the clean energy development.

In advance of any wave project development, we evaluate the wave energy resource based on the local wave statistics including wave height, period, seasonal distributions, directional probabilities and tidal change. We also carefully analye the local electricity demand, cost of electricity as well as the government incentives at the particular location to identify the most promising sea site for wave energy generation. Utilizing our unique methodology and advanced in-house software, we can deliver an optimal configuration of Drakoo for best economic return.
