Abstract
Taiwan east cost are full of ocean energy, especially Ocean Thermal Energy Conversion (OTEC). Offshore 3 km away from Hualien cost or Taitung coast will reach 1,000 M to 1,500 M. Their temperatures are around zero to 4 degrees, while surface temperature around 25 to 28 degrees, temperature difference is more than 20 degrees. If ammonia is used as the catalyst, it is easily to generate electric power. Offshore 33 km from Taitung coast and about 5 km from Green Island, there exists 3~4 knots’ Kiroshio current. MOEA is currently planning to develop 3 giga watts power. For the convenience to develop the Ocean Energy and Ocean Resources, the planning of an airport and seaport is shown in Figure 1 for future transportation of energy and Deep Ocean Water (DOW) products. The SHOTEC power plant is a good solution of OTEC. That scheme not only offers three times thermal efficiency to that of a conventional OTEC plant but also circumvents the difficulties of deployment of deep seawater pipe and evaporator biofouling problem. Therefore, this power plant has advantage of (1) combination of solar and deep seawater energy; (2) without carbon dioxide emissions and waste storage problem; (3) sustainability. This complex ports involve ocean engineering arrangements of ocean engineering installation, DOW intake pipeline, OTEC Fish Coral Reef, etc., and seaport facilities of DOW R&D Center, value added center, logistic center and Tourism Recreation Center. DOW products and mineral DOW water involve cold floral, cold seafood, cold fishery products etc., will be fast transported by this offshore airport to keep their fresh and coldness. These complex ports (seaport and airport) will develop and enhance the eastern Taiwan’s economical development. The ocean energy development of Taitung is welcome an international technical cooperation to participate its ongoing promotion and future developing.
