NoviOcean vs. Competitors

Unveiling the Superior Advantages of NoviOcean in Ocean Energy Extraction

These common concepts work primarily by resisting the moving water particles

How effective are they?

The average power or Capacity Factor is what that generates revenue, not the rated power which might be reached only once a month. This is a major differentiator between NoviOcean and its competitors.

Comparing the effect of particles vs. buoyancy

NoviOcean’s lifting force by buoyancy is
600 tons in four-meter waves for a float
net area of 260 sq. meters (38 x 8 m)

 

As graph shows, the solutions not using
buoyancy need about 30x larger area to
create a similar force. This equals about
8 000 sq. m or 800 x 10 meters, which will be far too heavy and costly

 

To extract the needed high amounts of
energy per ton of material in the ocean,
buoyant concepts are in our opinion the
only realistic solution. The others are
simply way too costly vs output

These concepts work by utilizing the buoyancy force (Archimedes law) (2)

• Huge lifting force will be possible relative to size and weight

• Then two types to choose from:

Round Point Absorber (Typical Solution) 1

Rectangular Point Absorber (NoviOcean) 2

Rectangular Point Absorber (NoviOcean)

Which to choose ?

Round or Rectangular?

Round

Max practical diameter: 10 meters

Max lifting force: 150 tons

Average power at medium site: 90 kW

NoviOcean

Rectangular

Float size: 25-38 x 8 sq. meters

Lifting force: 600 tons, 4x more (patented)

Average power at medium site: 250 kW

Next stage: 2 MW rated (1 MW average output)

Which to choose ?

Cogwheels or Hydro Power?

Cogwheels

Using cogwheels, wires and accumulators:


• Needs many giant, heavy and costly cogwheels and
accumulators to convert 600 tons of force at slow
0.5 m/s wave movement to 1000 RPM
• Substantial wear (metal to metal contact)
• Maintenance and reliability challenge

NoviOcean

Hydro Power

Using the hydraulic cylinder & the hydro power plant
concept:
• Resilient, light & durable which easily lifts 600 tons
• Easily converts 0.5 m/s wave motion to 1000 rpm
• Less wear (water to metal contact)
• Small Pelton turbine lasting for +30 years
• Well-proven over 200 years

Cogwheels

• Needs many giant, heavy and costly cogwheels and
accumulators to convert 600 tons of force at slow
0.5 m/s wave movement to 1000 RPM

• Less wear (water to metal contact)

Resonant

• Moving with the same or higher amplitude
than waves
• Works best in wave periods of 4-7 seconds,
not the common ones of 7-12 seconds
• Deep in the water due to high weight
• High surge/anchoring forces
• Difficult / impossible timing and loading due to constant change of wave height/length
• Requires complex expensive machinery

NoviOcean

Non-resonant

• Moving with a lower amplitude than waves.
• Works in all wave periods and conditions.
• Simpler since no timing is needed.
• Light, with low free-floating draft (like a
large surfboard) with high survivability.
• Anchoring/surge forces measured at only
1/20 of lifting, unique in wave power.
• Moves slowly only for ½ wave height with
high force, less wear & simpler machinery

NoviOcean

• To extract 3-10 times more power per unit,
• To be economical and with low LCA,
• To provide stable and secure energy,
• To last for 10 000 cycles per day,
• To have high survivability (being high in the water with low relative surge forces),
• To achieve similar costs per MWh as offshore wind before 50 MW deployed,
• And to achieve a carbon payback time of less than two years,

An effective Wave Energy Converter (WEC) needs to:

• Use buoyancy with a rectangular float shape,
• Be attached to the seafloor to fully extract the lifting force,
• Use the well-proven hydraulic cylinder to take the huge load,
• Use a hydropower plant concept to convert the slow wave motion to high-speed rpm,
• Be non-resonant and hit every wave, also the longer ones, with a simple system

Conclusion

We believe there is only one logical answer to these requirements:
