What if the sea itself could power coastal communities?
TA9A Shark is a near-shore wave and tidal machine for ports and fishing cooperatives that pay for diesel today.
I grew up 200 metres from the sea, and every summer the power still went out. That question became TA9A.
Morocco has the coast. The mix has no marine column.
About 3,500 km of coastline. 4,851 MW of renewables at the end of 2025, and no marine capacity listed.
Off-grid ports and fishing cooperatives along the coast still pay for diesel. That is our customer, and our competitor.
of coastline, about 3,000 km on the Atlantic
average wave power at the best sites on the central Atlantic coast
The resource is there. That study measures up to 262 MWh per metre a year, and it is more than four times stronger in winter than in summer.
It covers the Atlantic only. Our model uses Mediterranean sea states, so the pilot has to measure the real site.

One frame captures waves and tide.
TA9A Shark pairs a wave mechanism and a tidal turbine in one near-shore unit.
12A float drives the Scotch & Yoke mechanism.
A submerged Gorlov rotor takes energy from moving water.
- About 10 kW average, modelled
- Near shore, sized for a port or a fishing cooperative
- Sealed generator housings
- Rectifier, MPPT and LiFePO4 buffer, with telemetry to shore (design)
- Bench MVP built. The 13 m prototype is the next build.
Three iterations: ECOTIDETECH (first concept), the hybrid bench MVP, and TA9A Shark.
From the sea to the shore
The model says 10 kW on average.
Everything else follows from that one number. It is an annual average, so real output will move with the sea.
Simple payback on a €14,000 unit (proposed)
| Average output | Diesel avoided a year | Payback |
|---|---|---|
| 10 kWmodelled | 87.6 MWh · €43,800 | 3.8 months |
| 7.5 kWscenario | 65.7 MWh · €32,850 | 5.1 months |
| 5 kWscenario | 43.8 MWh · €21,900 | 7.7 months |
Before installation, service, finance and taxes. Assumes all output displaces diesel at €0.50 per kWh.
Same machine, four prices of electricity
| Illustrative scenario | Avoided cost per kWh | Payback |
|---|---|---|
| Morocco · off-grid diesel | €0.500 | 3.8 months |
| Italy · industrial | €0.247 | 7.8 months |
| Spain · ports | €0.190-0.200 | 9.6-10.1 months |
| Morocco · grid connected | €0.097 | 19.8 months |
Tariffs are assumptions for comparison, with 87.6 MWh a year and a €14,000 unit in every row. Each customer needs a site quote.
Two ways to buy
You own the machine. Proposed price €14,000.
We own and maintain the machine and you pay for the electricity. Service tariffs are not agreed yet.
Impact, stated carefully
About 61 t of CO₂ avoided a year per unit, if it displaces diesel (0.7 kg per kWh, modelled). Effects on cold storage and cooperative income are unmeasured. The pilots will measure them.
What it costs to build
€689M in theory. €2.1 to 3.5M in five years.
49,225 potential units × €14,000. The hardware value if every addressable site bought a unit. It is a build-out figure, not demand.
The Moroccan share. A planning estimate: there is no site list behind it yet.
150 to 250 units, 0.3 to 0.5% of TAM. A target, not an order book.
The global wave and tidal market was about USD 646M in 2025, heading to about USD 1.42B by 2034 at 9.1% a year (Precedence Research). Analysts’ estimates vary widely, from about USD 0.6B to 2B for 2025.
What exists today.
A €12,000 GreenUp Morocco award, secured and non-dilutive.
PhD at FST Tangier on modelling and control of a hybrid marine renewable energy system. Supervisor: Prof. Mustafa Ouardouz, Université Abdelmalek Essaâdi.
A private coastal operator has approved prototype testing at its site. Maritime authorisations still need confirming.
What the pilots have to settle
| Risk | Mitigation in the design | What phase 1 funds |
|---|---|---|
| Storm loads | Submerged rotor and a defined safe state | Structural testing and load validation |
| Biofouling and corrosion | Sealed housings and replaceable parts | Exposure tests and service records |
| Permitting | Site-specific authorisation process | Safety studies and permit dossiers |
| Output below model | Meter output against sea state | Continuous metering across 3 to 5 pilot sites |
Mitigations are design intent, not proven performance. Lower output reduces the value of every unit. The raise funds the measurement.
€600,000 for 18 months.
Every euro is tied to one deliverable: a measured output record from the sea.
13 m prototype, sealing and structural tests
Manufacture, install and monitor at 3 to 5 sites
Studies, dossiers and compliance work
Metering, telemetry and client reporting
Design freeze and costed bill of materials.
13 m prototype at the secured site. Metering begins after commissioning.
Deployment at 3 to 5 pilot sites.
First paid contracts. All milestones are targets.
A measured output record from the pilot site. A full year of sea data needs 12 months after commissioning, so it arrives after month 18.
Morocco first. An indicative €1.2M round to expand across the Mediterranean follows only after metered output, a service record and paid contracts.
