With the major drive to reduce the amount of carbon emissions going into the atmosphere, renewable energy has gainesd significant interest. Solar, wind, and wave are the most prominent solutions but have major drawbacks. The energy that is produced is on an intermittent basis, i.e., solar is ineffective in the dark and without sufficient wind and waves, turbines do not produce output. And, as stand alone technologies, they lack storage options for the energy produced. How is industry tackling this fundamental problem and what emerging soulutions are the most promising for the near future?
