Provisional Patent Application Filed

Renewable energy (clean energy) is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy replaces conventional fuels in four distinct areas: electricity generation, air and water heating/cooling, motor fuels, and rural energy services. A clean energy revolution is taking place across America, underscored by the steady expansion of the U.S. renewable energy sector. The clean energy industry generates hundreds of billions in economic activity, and is expected to continue to grow rapidly in the coming years. There is tremendous economic opportunity for the countries that invent, manufacture and export clean energy technologies.  

Wave power is the transport of energy by ocean surface waves, and the capture of that energy to do useful work such as electricity generation. Proposed here is an ocean-wave energy conversion system (OWECS) optimized for energy capture and capable of delivering to the grid levelized power that meets current utility standards for power quality. The system is capable of converting the mechanical energy from the ocean wave into electrical energy. No gearboxes or grid-interface power transformers are required. These attributes result in grid- friendly power delivery and greatly increased market acceptance. They result also in improved reliability and comparable Cost-of-Energy (CoE) relative to current designs that are not able to deliver levelized, utility-standard power

Reference Number: D-1206 

Market Applications:

The market for ocean wave power generation is expected to grow in the coming years due to the shift in finding alternative and renewable sources of power generation. Also of note: due to the current political climate that tends to unfavorably dictate the oil and gas industry, Energy industries are moving toward renewable energy sources like using tidal waves. As a result, new markets for ocean-wave energy conversion system (OWECS) may arise over the coming decade. 

Features, Benefits, & Advantages:

  • Reduction of imported energy 
  • Reduction of energy-related emissions
  • Renewable source of energy
  • Alternate source of generating power
  • Environmentally friendly
  • Abundant and widely available
  • Enormous energy potential
