SeAbacus: device for producing energy from wave motion

Circular economyEnergy convertermarine energytidal powerWave energy


SeAbacus is a point absorber type floating wave energy converter, efficient also in low-energy climates thanks to its modest inertial movement. It is scalable, small, modular and therefore installable in parks and at different depths.

Technical features

There are thousands of wave energy converters on the market, however few of them have passed long-term offshore tests due to numerous technical problems or excessive energy production costs: poor conversion efficiency, use of expensive raw materials, etc. SeAbacus is a floating device and does not require the construction of fixed and impacting structures on the shore or on the seabed. It has small dimensions, ensuring a minimal visual and environmental impact. The device has several advantages: i) it allows to obtain energy from waves coming from all directions; ii) is made with recycled / recyclable materials; iii) it has low inertia to generate electricity even in mild climate seas; iv) it can be installed in shallow to deep waters, where the sea is more energetic; v) it has a simple geometry, to minimize production costs, and is easily disassembled for maintenance, to minimize the costs of the operation. SeAbacus operates at depths between 5 m and 50 m. TRL: 2.

Possible Applications

  • Provide energy to ports and coastal communities without the need for major structural works;
  • Supply energy to small islands and areas of naturalistic interest;
  • Integrate into hybrid power generation installations;
  • Provide energy for the reuse of decommissioned offshore platforms.


  • Device modularity;
  • Power production also in mild wave climate;
  • Use of recycled or recyclable materials;
  • Low production costs;
  • Device modularity.
