§.1.1. The concept | Factory ships producing hydrocarbons with H2 from a fleet of automomous WEC's with internal electrolysis. |
The History |
In May 2006, in reaction to the demolishing of the French aircraft carrier 'Clemanceau', I launched an appeal to the
OECD (OESO) to convert this ship into an H2 producing factory from ocean waves, named 'OCeanspHider'.
This factory ship should be a combination of a submarin and tanker with on wave level a open area and above a hollow platform for habbor connections. In and around the open space different kinds of wave converters.
In March 2008, I asked an EU body for support with further development but this found no resonance. In November 2009 - after a meeting - I received an extensive email from innovation engineer Elke De Rijck (now VLIAO consultant) with advice and a lot of useful links and references to institutes active in domains of interest. Many other ideas and career opportunities interfered, but the concept of Seanergy.be as a fleet for open ocean matured further due to my analysis that the Pelamis Wave Power - although I admire the clever idea - would not succeed, that prediction came true in 2017. That was an indirect endorsement of my approach. In April 2022, I received a response from VLAIO to my announcement of an extension on the 2006-2009 idea with autonomous satellites (Sea.wiggle.R) to produce H2 which can then be tapped by the factory ship. In mid-2023, all parts fit together (transferring motion, generating electrical potential, filtering seawater, electrolysis, storing gas) in a "light weight form" able to produce continously and should survive rough seas. |
Ambition |
Harvesting the enormous wave potential of the open oceans as tidal, deep-water flow, off-shore wind and waves on the continental
shelf will not be sufficient for net-zero CO2.
The main goal is to make the whole operation profitable through a high net energy yield. So, it makes sense to start with an aggregate slightly anchored setup or to add Sea-wiggle.Rs to a windpark. |
The aims |
Seanergy.be is the concept of converting energy of waves for seawater electrolysis and processing the
hydrogen on board of a factory ship for the synthese of tailor-made hydrocarbons using carbon from CCS or DAC.
A factory ship plus a satellite fleet of gas producing WECs will both operate in an international authorised area in open ocean. The factory ship(s) taps the gases from the WECs and relocate multiple units to a starting point. |
Overview of components |
The ocean side: Seanergy.be
= Factory ship (OCeanSpHide.R) + fleet of autonomous free-floating WEC's (Sea-wiggle.R) + distribution on land.
The land side: Harbor facilities
|
The means |
The consequence of choosing direct electrolysis is that a certain electrical potential must be generated. The conversion of
ocean waves to existing generators can only be done with a complicated and therefore fragile transmission mechanism. I considered this as
losses and developped a workaround.
The irregularity of ocean waves dictate a none 'end-of-run linear' or a none '360° rotation' generator for electrical potential.
The organic load of seawater requires filters that must be cleaned.
The salinity of seawater requires purification on a robust way.
The environmental and decentralized conditions demand for stand-alone operational capability.
|
Prospects |
Existing and abondonned off-shore platform can be converted into massive carbone capturing systems,
which can use the gazes delivered by the factory ships to produce customised and high-value hydrocarbons.
After the mechanisation, sytems can integrates with existing loading, storage and distribution infrastructure. |
Consequences | The development and availability of ‘deep blue’ hydrogen reduces the pressure on ‘green hydrogen’, which actually suffers from a low total efficiency due to the conversion factors in the 'solar panel - voltage convertion - electrolysis - synthesis' combination. |
Ocean conditions | The challenges faced by designers were summarized in
https://en.wikipedia.org/wiki/Wave_power.
Most designers of WEC try to resist the forces of nature.
|
Drifting |
Drifting is a balance between water currents and wind in relation to the impact they have on the object.
(https://journals.ametsoc.org/view/journals/phoc/52/5/JPO-D-20-0275.1.xml).
In order to master the navigation some systems with a view on minimal energy consumption, are proposed. |
§.1.2. Societal gains | This concept could compare favorably with regard to material use, productivity and is climate-friendly |
Availability |
Guaranteeing that electricity will always be sufficiently available requires either a larger number of plants and/or more
interconnections (more dead time is not climate friendly anyway).
Imbalance between supply and demand is due to the fact that wind turbines, solar panels and anchored WEC's and tidal installation are site specific and their output depends on the frequency of suitable input. The use of buffers is necessary but they can only absorb imbalance temporarily. |
Profitability |
The commercial advantage of the Sea-wiggle.R is that (higher / constant) yield is manageable by:
Profitability depends most on productivity over 365/365 and 24/24. |
Redundancy & Reusability | The Seanergy.be concept in its entirety allows us to consider whether some functions need to be redundant. With tree energy pillars, optimal hydrid systems can be achieved. |
Personal- Family- Community- related facilities |
Because of the e-transition, we are moving towards decentralised energy generation but centralised distribution via the e-grid.
It has its advantages when DeSox and DeNox, and soon DeCOx installations, become mandatory.
The phasing of which processes need to be electrified first is extremely important, otherwise CO2 emissions will not decrease, but will saturate the atmosphere more. On the other hand, in the long term, climate engineering will regulate the CO2 emissions necessary for biomass production to replace natural processes due to the decreasing vegetation on the earth's surface. The only two criterion for choosing between combinations of full electrification and plug-in hybrids is the delta CO2 emission over the entire branched manufacturing plus construction chain but also the seizure of materials in a global context. This means not only choosing emission-poor processes, but also scheduling avoidable demolition of infrastructure and engines before end of their lifespan, this is not climate friendly. I have tried to construct an indicator for this (see HEATT plus examples) Pluspoints of plug-in hyrid mobility:
Pluspoints of hybrid home heating:
Questions and drawbacks:
Pluspoints of hybrid community facilities:
|
Autonomy | Europe has extensive knowledge in the field of shipbuilding and off-shore constructions. The development of this new industry will reduce our dependence by balancing our demand for rare materials and imported energy carriers. |
Optimisation | Liquid fuel or electric power have a totally different picture in terms of energy losses from their generation to the point of consumption. Idem for the energy needs to build and maintain their infrastructure able to meet the variable demand. The larger the grid, the lower the efficiency. |
§.1.3. Environmental gain |
Harnessing wave energy is much less questionable than harnessing wind and solar energy, both of which have a role to play in natural processes. |
Climate caution |
Wind has a mixing function: diffusion of vapour, dust and emissions from fauna and flora, driven by rising hot and
falling cold air and influenced by the Earth's rotation. It is an indirect form of solar energy.
A question about this mechanism, is to what extent does tapping sunlight and changing shape and location of hard surfaces, thus their energy content, affects ecological cycles driven by warming and cooling ? And perhaps the deceleration of lower laminar air flows due to off-shore wind farms should be investigated, and whether rainfall in the lowlands and hinterlands after a mountain range is unevenly distributed as a result. |
Phasing in circular fuels |
Phasing out means diminishing the CO2 concentration in the atmosphere by increased photosynthesis for biomass and by
introducing chemical carbon capture for storage and utilization in circular hydrocarbons.
|
Profitable symbiosis |
The realisation of CCU/S and Seanergy.be would enable to convert CO2 into soil conditioner. Combined with Sol.d'eau.R (water distillation), this could make deserts fertile for forests, livestock and vegetables. |
Two warnings |
Energy needs:
|
Demolition is not climate friendly |
Demolition carried out by CO2 emitting machines or by electrically powered machines that were first produced using CO2 emitting techniques, is a mindless hasty action. Accelerating R&D in chemical capture and conversion to HC and circular e-fuels will prevent the avoidable climate-unfriendly demolition of existing infrastructure. |
Attention | We should consider whether some climate changes are not necessary to feed 10 billion people, their pets and our productive livestock? A high CO2 concentration is not the only cause of climate change - read about it in eco-participation on this website. |
Decarbonization |
The Sea-wiggle.R also produce oxygen that can be delivered to CO capture facilities to convert to CO2.
Decarbonization in circular e-fuels is primarily an efficiency gain, because hybrid systems combine the optimal operating points of internal combustion engines for charging a battery with an electric motor for propulsion and in the meantime huge amounts of CO2 are immobilized in stocks. |
Avoiding new CO2 |
The cheapest decarbonization and best climate mitigation and fastest way is avoidance of raise of atmospheric concentration.
Challenges and eventual drawbacks are outweighed by climate benefits like climate-friendly continuation of existing distribution infrastructure with e-fuels and by CO2-neutral smoothing of irregular yield from wind, solar by powerplant on liquid / gasous circular HC's as they can be stored, transported and burned in multiple ways and facilities. |
Highly sustainable |
The proposed wave energy conversion is a climate-friendlier option as source for renewable energy, because its
kinetic and potential energy content is partly of planetary origin.
While actual solar and wind renewable resources also have a nature conservation function (photosynthesis or mixing) that cannot be reduced without consequences. |
Less pollution | The big amenity of electrification is the reduction of pollution by fossile fuels. Pushing back pollution can also be achieved with synthetic fuels and CCS and hydrid applications supported by R.E-expande.R. Liquid hydrocarbons (HC) from Seanergy.be can be customised to particular purposes without the pollutants in crude oil. |
Climate solidarity |
Full electrification sacrifices nature at the level of (open-cast) mining when the damage is irreversible: Vast areas are
destroyed in terms of landscape relief, soil stability, underground and surface water management.
More mining causes a reduction in biodiversity due to polluting extraction methodes. |
§.1.4. Intervention aspects |
Delivery reliabilty depends on the vulnerability of the production units and on the number of degrees of freedom in modes of transport. |
Dual Use some examples |
When time is crucial !
|
Hydrid efficiency | Hybrid applications have a lower total energy loss. In combinations of an internal combustion engine and an electric motor, both can operate in optimal regimes. In addition, an electric motor can recover kinetic energy and a combustion engine provides heat for comfort and battery, so battery capacity may be lower. |
Flexibility & Readiness |
Liquid fuels will therefore remain preferable for their high energy density and their flexibility in quality, container volume and shape, transportable to any place, in cases where infrastructure might fail. |
Quality of e-fuels | Thanks to their production method, e-fuels are very pure. Purified petrol, for example, has the advantage that an engine that is stationary for a long time can still start smoothly. This is important for less frequent interventions. |
Vulnerability |
Vulnerability depends on the time it takes to locate and destroy, which is less for fixed assets like windmill or platform than for foating vessels.
The floating units are not a target due to their number and small size, the variability of the ocean waves makes them difficult to hit. About the MTTR/R: Accessibility of wind farms to restore or to replace is a main factor in recovery. |
Defensibility | The concept in question has no need for cables or pipelines to the mainland. The fewer objects to protect, the less surveillance is required. |
§.1.5. Redundancy | The question here is whether we opt for two systems or one double-sized system: { 1+1 ≠ 1x2 } ? |
Security of Supply | Is economical performance / efficiency in all cases conclusive ? The hierachy of Maslow do not put these indicators first. |
Convertibility | This notion is seldom used in strategical studies. But it is worth while in view of shortage due to conflicts of all kind. A liquid fuel can be converted easily into electricity, but not the reverse. And it can be done on almost any scale nor does it require an intact network. |
Resilience | Resilience can be interpreted in terms of protection and defence but it concerns also the periods before and after a conflict. Many diverse common interests are a good way to avoid being blackmailable from one side. The possibilities of Seanergy.be in this scenario are evident. |
§.1.6. Employement | Not only large but also local shipyards and construction workshops benefit from this new economic sector. |
Jobs at various levels |
It will take engineers and technicians and skilled workers to design, modify and assemble a
large number of the Sea-wiggle.R and its components.
A big advantage for job distribution is that the size of a Sea-wiggle.R also allows to be assembled deeper in the hinterland and then transported to docks. |
Exporting energy | It lies in the technical possibilities of sending out a fleet of such factory ships with accompanying Sea-wiggle.R's to various ocean areas to provide countries with renewable energy during their transition. |
Leverage for profit |
Realizing this vision means focusing on R & D towards decarbonization direct at the exhaust of thermal
intense industries (like desox and denox at of powerplants, crackers, blast furnaces, etc) or DAC.
The implementation implies that certain R&D will have to accelerate and that rapid deployment requires strong guidance and commitment from many at multiple political and industrial levels. |
2. R.E-expande.R | |
---|---|
§.2.1. The concept | A mechanical way to buffer electrical energy in the form of potential energy in chemical bonds and crystal lattices under tension as ion-bonds are stronger than covalent bonds. |
Components |
Three variants were developed with different energy-densities in three technical embodiments (not the scale). All three have:
|
Features |
Some characteristics peculiar to mechanical systems:
|
Embodiments |
Prefered allocation:
|
§.2.2. Advantages for citizens |
Social justice requires an equalization of prices. (a family that gives birth at night compared to a family that waits until the afternoon sun ?!). |
Strategic considerations |
The absorption of asynchronous production versus consumption of electricity from renewable sources can only be achieved
in three ways, each with a different cost and security of supply.
|
Optimisation | The three proposed variants of R.E-expande.R have the same technique but slightly different configurations and materials, in order to save on weight and complexity with a slight consequence to capacity. |
Comparison |
Versus batteries
|
§.2.3. Environmental gains |
The three variants have different sizes by destination but also different construction needs that are easily definable according to the wishes and possibilities of a location or a purpose. |
Reuse of infrastructure |
The design of the high-density variant was based on the use of unused cooling towers. Not only the reuse of a building is an asset, but also the reuse of the existing cabling is cost-saving. |
Local | The medium density variant is intented for stationary setup but transportable. Multiple units in a local grid can profit from the fluctuations in production and in consumption. This is especifically an optimization exercise. |
Material cost | Although advanced composites or alloys are preferred, if they meet certain requirements, smaller variants can also be made without specialties, bringing them into the reach of developing communities that can also install a wind or solar generator. |
§.2.4. Intervention aspects |
A general plus point, especially for smaller installations, is that this configuration can be charged with either an electric or combustion engine. |
Second asset | Another important advantage is that charging time does not depend on the characteristics of a 'battery', but on the capacity of the source and that the supply by mechanical input does not need to be stable. |
Mobility | The lower density variant is designed for road assistance and fast first remote relief after a desaster or accident. |
Maintainabilty | Repairability depends largely on material choices. Thus, available materials, craftsmanship and resources can be taken into account in design. The whole structure is necessarily robust, and repair or deactivation of any part is within the reach of many technicians. |
Comparison |
Versus batteries:

3. Sol-d'eau.R | |
---|---|
§.3.1. The concept | Desalination during inland transport with (in-)direct solar energy and ev. residual energy of any regime. |
Origin |
The essential idea was born during a crossing of Lake Kivu in 1983. In the period 2003 to 2010, the
entire design was drawn in 3D and a patent description was started.
Not only geometry was shaped but also material features which came available in the years around 2000 in universities in Ghent and abroad. These features have an promoting effect. |
Shape follows function |
The evaporation and condensation take place in a pipe-line during transport.
However, the design is not as simple as imagined at first glance.
A complex spherical configuration ensures that all physical laws involved in evaporation / condensation will, in this geometry and with defined material featues, interact in a mutually promoting manner to achieve their maximum effect. |
§.3.2. The SDG's | A succesfull development will entail that area's with a shortage of rain or irrigation can be made productive and stop climate related emigration. |
Assets |

Higher Yield |
RO is currently one of the prefered applications for making drinking water as it has better overall energy efficiency
over classic solar stills and other techniques.
RO is a technique that creates high pressure to counteract spontaneous osmosis at atmospheric pressure. While Sol-d'eau.R is a 'model' that creates conditions that bring together all spontaneous physical equilibria within normal atmospheric conditions. In both cases, energy is used to overcome physico-chemical potentials. For Sol-d'eau.R the molecular attraction among H2O and some ions that must be delivered to provoke evaporation. But, for that matter, the advantage of Sol-d'eau.R is that the heat of evaporation is recovered by condensation and is reused to the maximum extend. Moreover this model can accept rest energy of different types. |
Horticulture | These modules can be connected in line or in parallel and are thus extremely suitable for use in synergy with solar roofs over horticultural fields: see for details in theme: Combined Capacities theme. |
§.3.3. Design Parameters |
The internal configuration uses multiple physical laws, therefore the ratio between dimensions needs fine-tuning. |
Optimalisation |
For practical reasons, as well as to create shadow, it is advisable to mount the pipeline on pillars. I guess that dimensions for
some efficiency will be between 3 and 6 meters in diameter at a height of ± 3,5 meters.
The internal configuration can be optimised with a multi-physic modelling. COMSOL is powerful mathematical software tool used for simultaneous simulation of different aspects of a physical system and the interactions among physics phenomena. Such a modeling simulates also the yield. In this case it should solve mass and energy balance equations in the multi-effect evaporation-condensation cycles with flow dynamics. ANOVA can eventually be used to identify the factors that make the greatest contribution in the whole of the Sol-d'eau.R design as there is an absolute non-obvious factor in the design. |
Architectural masterpieces |
Because Sol-d'eau.R is both beautiful and functional it can actually serve as a shade supplier in cities around the equator.
Residual energies are therefore abundant and can be used for the production of drinking / spraying water.
Such applications in various sizes and configurations will also have a positive effect on the micro-climate in a city. |
