Japan is the first country in Asia to conduct the ocean energy utilization research and application; South Korea and Australia have rich ocean energy resources and propose the specific objective to develop the ocean energy; the Southeast Asian countries have rich temperature difference resources, which establish the Southeast Asian Ocean Energy Union.
Recently, Japan, South Korea and Southeast Asian countries have increased their capital input in the ocean energy development and utilization technology.
The development speed of the countries in the Asian-Pacific region in terms of R&D of the ocean energy technology, device sea trial, test field construction and even commercial projects is higher than that all over the world and some representative technologies have reached the world’s advanced level.
Set an active ocean energy development objective. Japan is the first country in Asia to conduct the ocean energy utilization research and application. In 1974, it issued the “Sunshine Program”, which is a special program of ocean energy development. In 1993, it started to implement a new “Sunshine Program”, which effectively promoted the technical R&D of the temperature difference energy. In 2003, It started to implement the renewable energy quota system to promote the renewable energy development and utilization and proposed that the renewable energy would account for more than 50% of its energy supply by 2050. The marine ranching development of Japan drives development of the ocean thermal energy and wave energy power technologies and comprehensive utilization. In 2010, the comprehensive development agency of new energy industrial technology of Japan proposed the objective to construct 10MW temperature difference energy power station by 2020 and 50MW power station by 2030.
South Korea has rich ocean energy resources such as tidal energy, which develops the ocean energy technology with introduction of the ocean energy technology and independent research and development. According to the renewable energy quota system implemented in 2012, it proposes to achieve the objective to make the renewable energy power generation account for 8% by 2020, with the ocean energy accounting for 2.4% of the national renewable energy power generation.
The Southeast Asian countries have rich ocean energy resources. In particular, the temperature difference energy resources in the countries in the tropical areas are very rich. In order to support development of the regional ocean energy development and utilization technology and give play to their advantages, the Southeast Asian countries pay much attention to the cooperation between countries in this region. In 2013, Brunei, Indonesia, Malaysia, Myanmar, the Philippines, Singapore, Thailand and Vietnam established Southeast Asian Ocean Energy Union to strengthen knowledge sharing of the ocean energy and technical innovation.
Australia also has rich ocean energy resources such as tidal energy. According to the renewable energy quota system implemented in 2001, it proposes to achieve the objective to make the renewable energy power generation account for 20% by 2020.
Increase the capital input. In order to accelerate to promote development of the ocean energy development and utilization technology, Japan input about 7.8 billion yen from 2011 to 2015 to promote development of the ocean energy technology. In 2011, the comprehensive development agency of new energy industrial technology of Japan established the capital support program of ocean energy demonstration and application project, which has input 2.7 billion yen in recent two years.
In recent years, South Korea has had outstanding R&D progress in the ocean energy technology. In order to achieve its objective to make the ocean energy account for 2.4% of the national new energy and renewable energy power generation by 2020, its government announces to input more than USD 700 million to develop the ocean energy technology in the following 10 years.
Recently, the Southeast Asian countries have increased their input in the ocean energy development and utilization. Singapore is actively promoting the construction of the tropical ocean energy test field; Malaysia pays much attention to the temperature difference energy development utilization and is formulating the special laws and regulations on the temperature different energy development; Indonesia also establishes the ocean energy union to promote ocean energy development.
Some representative technologies reach the world’s advanced level. In recent years, the Asian-Pacific emerging ocean energy market has attracted more and more attention from across the world. The development speed of the countries in the Asian-Pacific region in terms of R&D of the ocean energy technology, device sea trial, test field construction and even commercial projects is higher than that all over the world and some representative technologies have reached the world’s advanced level.
Tidal energy technology: The Sihwa Lake Tidal Power Station constructed by South Korea in 2011 has 254MW installed capacity, which is the largest tidal power station all over the world, with its annual energy output of 550,000,000KWh. In addition, South Korea also proposes to construct the larger tidal power stations in Gorolim, Kanghwa and Incheon.
Wave energy technology. Carnegie Wave Energy Company in Australia completed the three-year demonstration operation with 200KW wave energy technology in 2011. While generating power, such technology also achieves the seawater desalination function. At present, it has signed the wave energy electric field construction agreements with several countries.
Temperature difference energy technology: Japan constructed a 120KW temperature difference energy power station in the Public of Nauru in 1981 and operated it as demonstration for several years. India constructed a demonstration power station in Minicoy Island in 2012 to generate fresh water with the temperature difference energy, with the daily fresh water output of about 100t. Japan constructed a 100KW ocean thermal energy conversion demonstration power station in Okinawa in 2013, which successfully generates the electricity. South Korea constructed a 20KW ocean thermal energy conversion test power station in 2013 and signed a cooperation agreement with Kiribati in 2014, which is a country in the Pacific Islands to develop a 1MW comprehensive utilization power station of ocean thermal energy conversion in Tarawa Island.
Enlightenment to develop the ocean energy in the Asian-Pacific region. The countries in the Asian-Pacific countries, especially countries in the Southeast Asia have not only rich ocean energy resources, but also strong desire to develop the ocean energy as well as improved regional cooperation mechanism. For example, the Asian Ocean Energy Center located in Nagasaki, Japan has signed a strategic cooperation agreement with the European Ocean Energy Resources Center to jointly promote development of the ocean energy industry of Japan and be committed to enhancing the ability to conduct the regional ocean energy test; Singapore pays much attention to the ocean energy and joined the Ocean Energy System Implementation Protocol of International Energy Agency in September 2014; India and Indonesia are also actively applying for joining it.
It is necessary for us to strengthen the regional ocean energy cooperation with all Asian countries, develop and improve the regional ocean energy partnership network, promote the cooperation with the relevant countries along the “One Belt and One Road” and cultivate the international ocean energy market to lay a foundation for the Chinese ocean energy development and utilization technology, equipment, standard and service to enter the international market.
