THE ENERGY CHALLANGE
- The worlds needs to transition to renewables to counter the global environmental crisis. We currently still source 87% of our energy from fossil fuels
- Conventional wind and solar have failed to outcompete with fossil fuels on power and energy density, cost and scalability
- Conventional offshore wind turbines are considered expensive at £3.3 million per MW installed and £140 per MWh (compared to fossil fuels at £80 MWh). Still losing on the economic argument
- Marine energy – tidal and wave energy technologies are still in development with no sight of commercialisation – very expensive at above £350 per MWh
World Energy Consumption
- Fossil Fuels (oil, coal, gas)
- Fossil Fuels (oil, coal, gas)
Levelised Cost of Energy per MWh
- Cost (£)
- Cost (£)
- Conventional offshore wind turbines have reached a plateau due to structural and efficiency limitations. Current commercial structures are economically limited to maximum water depths of 60m and heights of 150m. This restricts the potential to exploit offshore wind development in deep waters and at altitude where more stronger, stable, persistant and consistant winds prevail
- Wind has electrical conversion efficiency limitation of 35% (wind to electricity)
- Wind is considered no-dispatchable – the ability to increase or decrease power output on demand
- Wind is variable – wind speed increases and decreases varying the power and energy output
- Wind is generally intermittent – although offshore it is more consistent and with altitude stronger and more persistent
Electrical Conversion Efficiencies
- Renewables generally require subsidies to compete with fossil fuels
- Humanity is yet to harness the power of either oceans or wind offshore and deep sea
- How can we access and harness wind at altitude, deep sea and offshore, cost effectively?
- Energy storage – no cost effective solution has been found yet to store electrical energy sourced from renewables – the missing link to a future world powered by renewables
Thinking out of the box and simplifying how we generate electricity from wind - combining the power of oceanic pressure and altitude wind power
ENERGY GAME CHANGER
We are developing energy systems to harness the immense and consistent power in offshore low altitude wind combined with the power of subsea oceanic pressure to provide reliable, low-cost clean electrical energy and energy storage.
Wind turbines and other kite technologies convert the wind directly to electrical energy, giving a low conversion efficiency of only 35%. We use kites solely to provide mechanical power for linear movement to lift a submerged pressure vessel (similar to sailing). Water flooding into an empty pressure vessel at depth is used to generate electricity through a hydroelectric turbine (utilising differences of pressure and buoyancy between air and water under hydrostatic pressure). This in comparison gives a conversion efficiency of 90% with the added benefit of on-demand dispatchable power and energy storage. The missing link to a future powered by renewables.

We have developed a simple yet extremely disruptive energy system that utilises subsea pressure combined with low altitude kites to generate zero carbon emissions electricity. A low cost offshore power and energy generation unit that harnesses altitude wind and can be installed in deep waters utilising solely proven technology, hydroelectric turbines. The system indirectly harnesses wind power using kites at 100m to 300m altitude combined with a subsea system to store energy and release dispatchable power on-demand (the world’s first). The technology can satisfy the four imperatives of power density, energy density, cost and scalability to compete directly with fossil fuel power generation and outcompete all other renewable energy technologies.
The technology we are developing has the potential to completely transform the entire dynamics of the energy market in terms of on-demand dispatchable power from altitude wind, reliable energy generation, efficiency, electrification, lowering the cost of energy, scalability, security of supply, energy storage capacity, rapid development cycle and environmental impact.
This simple technology opens up the ability to exploit offshore deep sea wind power at significantly reduced cost compared to conventional wind turbines, offshore floating wind or evolving marine and kite energy technologies.
The kite system operates at altitudes of 100m to 300m where considerably stronger, persistent and more stable winds prevail. At an altitude of 300m the average wind speed is 50% higher than at an altitude of 10m, due to the absence of skin friction from the surfaces of earth and water. Wind power is a measure of the energy available in the wind. It is a function of the cube (third power) of the wind speed. If the wind speed is doubled, power in the wind increases by a factor of eight. This relationship means that small differences in wind speed lead to large differences in power.
- Rapid development cycle – commercially ready by 2018
- Absorbs the variability of wind – works in low wind speed and extreme wind
- System can be adapted to various sea depths and altitudes
- Easy to build, deploy, scale and decommission
- 5th of the price and twice as reliable as conventional wind – lowest unit cost – below £30 per MWh
- Simple technology that from the outset outcompetes fossil fuel based power generation. Requires no government subsidies
- Works here and now – based on proven technology – uses hydroelectric turbines, by far the most efficient method of electric power generation to date – efficiency upwards of 90%
- Harnesses winds at altitude where wind energy is stronger, more stable, consistent and persistent – sailing in the sky
- A simple method of harnessing wind offshore and at altitude
- On-demand power from wind – the world’s first – guaranteed power output: Regardless of the wind speed used to lift the pressure vessel the power output at the operational depth of the pressure vessel is guaranteed due to known pressure differentials
- Simultaneously solves the energy storage problem – as we build an array storage capacity increases for the overall system
- Zero Carbon emissions – environmentally benign technology
- Designed specifically for deep waters and offshore development. Out of sight less visual impact
- Guaranteed energy generation: energy generation is guaranteed since it relies on pressure differences and guaranteed water flows
- Power and energy density – sea depth increases power and energy density
500m³ PRESSURE VESSEL 1MW POWER OUTPUT:
- At 100m depth 5 min discharge 100 kWh
- At 200m depth 10 min discharge 220 kWh
- At 300m depth 15 min discharge 330 kWh
Storage capacity with the same volume increases linearly with the depth of the water. Every 100m depth the system doubles the energy storage capacity and the discharge time increases proportionally.
- Replacing wind turbines with altitude sails that can be deployed in deep water and survive extreme weather conditions
- Low operation and maintenance costs
- Reducing the mass of material used – high power to mass ratio
- No government subsidies required – technology wins on the economic cost argument
- Rapid permitting and consenting
- Opens global deepwater offshore wind market
- A renewable power system that can reliably match real-time energy demand
"Kite power could be the magic solution for global renewable energy needs."
