Ocean thermal energy conversion, also known as OTEC, is a promising form of renewable energy. Oceanic thermal energy is created when the heat stored in ocean water is used to generate electricity. The process works best when the upper layer of the ocean water is at least 36 degrees warmer than the lower, deeper layer. Because of this, optimal conditions for renewable energy from the deep ocean exist in tropical waters.
Ocean thermal power can be created with one of three types of systems: closed-cycle, open-cycle or a combination of the closed-cycle and open-cycle systems. Either way, ocean thermal alternative energy requires a large diameter pipe, submerged more than a mile into the ocean, to bring cold water to the surface. This is one of the engineering challenges that currently makes the process difficult and costly.
Before your company gets involved with ocean thermal alternative energy, consider taking the following steps:
1. Learn as much as you can about the ocean thermal energy conversion process.
2. Find programs that promote renewable ocean energy.
3. Research companies that are already in the business of ocean thermal power.
