A pioneering Australian startup, Deep Sea Energy, is on a mission to transform ocean thermal energy conversion (OTEC) from a prototype into a viable commercial product. OTEC, a concept dating back to 1881, harnesses the temperature differential between cold deep-sea water and warmer shallow water to generate clean electricity.
Deep Sea Energy is collaborating with the Korean Research Institute of Ships and Ocean Engineering (KRISO) to advance their 1-megawatt (MW) offshore demonstration, known as K-OTEC1000. The ultimate goal is to scale this technology into a formidable 100-MW commercial project, proving its efficacy in a volatile global energy landscape.
Despite the promise of OTEC, the venture faces substantial hurdles. Key among these are raising public and investor awareness, securing significant investment, and crucially, reducing the high levelized cost of electricity (LCOE). Currently, the LCOE for OTEC ranges from a steep $US145 to $US630 per megawatt-hour. While the Korean prototype successfully demonstrated functionality with a temperature difference as low as 20ºC, the economic viability remains a significant challenge.
The startup is actively exploring potential sites in Queensland and Western Australia, prioritizing locations near population centers and those suitable for green hydrogen production. New South Wales, unfortunately, does not possess the necessary temperature differentials for OTEC implementation.
Historically, OTEC has encountered engineering complexities, such as the demanding 1-kilometer long riser pipe, and has seen past failures in its development. Nevertheless, there is a renewed global interest in this technology, particularly from nations like Korea and Japan. Deep Sea Energy is at the forefront of this resurgence, striving to prove the commercial viability of OTEC and contribute to the world's sustainable energy future.
