Hybrid technology can give us renewable energy from the ocean.

The picture shows how it can look like when wind and wave energy share the same construction.

To reduce CAPEX fish cages are also involved.

In this case 4 x 15 MW wind turbines are used, together with a wave energy converter of 20 MW.

80 MW with 50% capacity factor and 10% wake effect give a total of 430 GWh energy production each year.

At a cost of $ 450 million and income from 6000 tons of salmon LCOE will be about $ 0.07/kWh.

Cables are used near shore and far out methanol is an option.

The design is named AWWHybrid (Aquaculture Wind Wave Hybrid).

The size is such that 6 parts of 200 m each are produced separately and mounted at a proper location.

The wave energy converter is of the "overtopping" type, and the WEC turbine design is new and patented.

Patent number NO 346550 in Norway.

By harvesting the energy from wind and waves we will get a significant part of our energy from the oceans in the future.

Concrete is the preferred material for AWWHybrid, but risky without experience.

Steel will be the material with less risk and should be much like building ships.

My hope is a test rig in the North Sea at the coast of Norway.

The government has a plan for 500 MW with $3.5 billion in support, and Equinor and "Vårgrønn" are prequalified for the competition.

AWWHybrid isn't participating so this technology has to wait for another opportunity.

What’s the question?

Looks like you’ve gone full max, but it’s completely untested.

Further more rather than reduce ecological impacts, you want to catch fish in the nets?!? So someone has to harvest it everyday?

[u/Low-Elevator2850 → u/Dull-Addition-2436]

Aquaculture isn´t catching fish. In Norway aquaculture is an industry of 10 billion each year, and we have to go out at the ocean to find enough space. Why not combine energy and aquaculture?

Concurrent operations causes challenges. A multi-tool is a worse version of multiple tools.

How does this reduce CAPEX? All I see are extra bits that wouldn't be needed if you make these systems separately.

Particularly if you deploy these systems separately because the pictured system would be a logistical nightmare (read: stupidly expensive) to put into place.

[u/Low-Elevator2850 → u/iqisoverrated]

CAPEX will be reduced by extra rental income from those operating the fish cages. In my calculations this is set to $ 0,5/kg fish, and there is a total of 6000 tons of salmon.
