The benefits of energy from tides are waving at us
The ocean’s waves are always in motion, 24 hours a day, 7 days a week, they therefore have the potential to be extremely reliable energy source. With tides known in advance, and waves being predicted a few days in advance, it has an advantage over predicting wind speed or the amount of solar radiation getting through on a day to day basis.
The availability of ocean waves is one of its great advantages. Waves are available 90% of the day on average, while solar and wind energy less so, especially solar which may only be 30% of the day.
There is also a clear seasonal matching between wave energy and electricity demand in many parts of the world, such as the Western U.S. and the United Kingdom. In some parts of the world, such as the densely populated west coast of India, there is even a daily matching of wave energy to electricity demand.
The practicality of wave energy
Obviously, wave energy can prove most helpful in coastal areas, which may be of significant importance given how densely populated our coastlines are.
We believe there our over 2 billion people living within 60 miles of an ocean coastline. According to NOAA, in the U.S. alone, counties directly on shorelines constitute less than 10% of the total land area, yet account for 39% of the total population. The population density of these U.S. coastlines is six times greater than inland counties.
Wave Vs Wind and Solar
Wind and solar energy generation require large footprints and clear airspace above it. Such footprints can conflict with existing or potential use of that land.
Solar and wind farms tend to be installed in areas away from the industrial developments.
Wind and solar can require ten times as much land per unit of power produced than fossil fuel power plants. In comparison, wave energy systems require far less space with little to no visual profile.
Wave energy converters work by setting up buoys in the water that move with the waves, harnessing the energy present within the wave motion. They are low cost to install and require no specialised boats or heavy lifting equipment – they tend to be small, light and easily maintained.
The tide is coming in as far as wave energy ans a renewable energy source is concerned.
Wave energy is progressing rapidly towards becoming an important source of renewable energy on par with solar and wind. With continued development support and funding, the potential for this renewable energy is abundant.
With its advantageous availability and potential application, wave energy’s future is ‘up there’ as a key, if not the key to sustainably harvesting all the energy we need alongside other technologies.
Technical Terms and Vocabulary
Process by which the solar panels are exposed to the sun’s radiation. Effectively how much power can be harnessed by a particular system.
A method of converting solar energy into direct current electricity.
Kilowatt peak, the output achieved by a solar module at full solar radiation.
Kilowatt hour, unit of energy equivalent to one kilowatt (1 kW) of power expended for one hour.
Megawatt peak, the output achieved by a solar module at full solar radiation. 1 MW is 1000 kW
Megawatt hour, unit of energy equivalent to one Megawatt (1 MW) of power expended for one hour.
Converts direct current (DC) electricity into alternating current (AC) electricity, which can be used by electrical appliances.
RPI (retail, price index) running at a percentage inflation per annum
Equipment embedded within a site, generating power through low carbon natural gas or via green generation technologies such as Solar PV or Onshore wind
Private wire generation
Equipment is located at a development nearby and power is provided direct from the facility via a “private wire”
providing a dedicated power plant and not being connected to the local or National energy networks.
Hausch and waves
We are delighted to be collaborating with award winning innovator Jan Skjoldhammer and his team at Noviocean on their rapidly developing wave energy converter. We want to help Noviocean in their development of this exciting new technology in whatever way we can.
Noviocean’s mission statement reads “Saving the climate with profitable wave power”.
“We see wave generated energy as an essential part of the mix in our facilitation and funding of renewable energy generation projects around the world”.
Wave energy technology is not new – it has been experimented with for a few hundred years but without any remarkable success. Other wave energy converters are, of course, out there, but they can be too heavy, fragile, complex, and expensive to manufacture, and above all, they provide less electrical energy than they would like to.
Noviocean decided on a completely different approach with the conviction that to succeed, it must be lighter than others, to bring down the cost and to keep it so high in the water that it is not torn by the waves. Likewise, it should be simple, based on well-known technologies, have few parts, and have high efficiency, and not the least, be inexpensive in relation to its output.

We are happy to walk you through the whole process from what “information is needed?” to “how long will it take?” to “Great! when can I start?” 🙂
We look forward to hearing from you.
