Wave energy is the largest unused renewable energy source on the planet, the European Commission says. How does it work, and how much power could it generate?
Energy storage technologies are fundamental to overcoming global energy challenges, particularly with the increasing demand for clean and efficient power solutions.
As with other oscillatory power conversion systems, the design of wave energy converters can be understood as an impedance matching problem. By representing the wave energy converter
Impedance is the opposition to the flow of alternating current (AC) in a complex system. A passive complex electrical system comprises both energy dissipater (resistor) and energy storage (capacitor) elements. If the system is purely resistive, then the opposition to AC or direct current (DC) is simply resistance.
Wave energy is the largest unused renewable energy source on the planet, the European Commission says. How does it work, and how much power could it generate?
The EU says wave power could provide up to 10% of its energy by 2050, cutting the need for back-up fossil fuel generation. 38 Across the world, the growth of wave and tidal stream energy could create 680,000 jobs and add USD 340 billion of value to the global economy, the International Energy Agency estimates. 39
This technique measures the impedance of a system over a range of frequencies, and therefore the frequency response of the system, including the energy storage and dissipation properties, is revealed. Often, data obtained by electrochemical impedance spectroscopy (EIS) is expressed graphically in a Bode plot or a Nyquist plot.
Today’s wave energy converters are many and varied, but all follow the same basic principle – turning the natural movement of the sea into mechanical movement, most often to power electricity-generating turbines.
For CalWave, CorPower and their growing number of peers, the potential prize to be had from wave energy is vast. Research suggests that we could generate almost 30,000 terrawatt hours of electricity per year from waves 11, which is around 20% more than the world’s total electricity consumption 12.
