Dualtower is a radical new concept for wind towers (Wind turbines).
It combines a new method of building a tower structure with the possibility to store hydrogen GAS in the vessels of the tower structure.

This is now possible because we are using CPV’s -Constructive Pressure Vessels- for the tower structure.

The CPV’s are made using commercially available materials (eg large diameter steel tubing) to assure having a cost efficient product.

The Dualtower can be advantageous for wind parks in a sense, that it offers balancing functions (store excess of energy and make it available when there is a shortage) and thus will increase the yield of the wind park as a whole.

BUT even more promising will be; installing clusters of Dualtowers in remote area’s with excellent and high wind occurrence and harvest the wind energy in the form of Ammonia. The chapter here below explains it.


How do we harvest the energy ? Producing GREEN AMMONIA.

Assuming you would like to benefit of the excellent wind conditions in for example  Patagonia, Namibi or New Zealand.

With clusters of Dualtowers you could achieve this; the wind is harvested and directly converted in hydrogen using electrolysers. This hydrogen is stored in the CPV's of the Dualtower.

Hydrogen in a chemical reaction with Nitrogen to produce Ammonia (NH3). The ammonia is stored in the tanks of a reaction ship. Ammonia synthesis is one of the oldest chemical reactions, also called as Haber–Bosch process.

Ammonia -in a liquid state- is much easier to transport than hydrogen gas. 

Compared to hydrogen gas at 30 bars, ammonia has a 50x higher hydrogen density:

  • 1 m3 H2 at 30 bars = 2,5 kg
  • 1 m3 liquid NH3 = contains an equivalent of 121 kg hydrogen

So with Dualtower and its dCPV's it will be possible to produce GREEN AMMONIA, totally FREE of any CO2 emissions.

To deal with the difficulties of hydrogen steel embrittlement, sealing issues and hydrogen gas permeation, the duplex CPV's are the ultimate solution. So at the same time we store the nitrogen in the dualtower structure. Each gas has its own storage segment in the dCPV.



Does it make sense using agricultural land to produce bio-fuels ?

Wouldn't it be smarter to install PV-panels or a Dualtower in non-agricultural area's and use the agricultural land for food production ?

This table compares the yields of 1 ha for several biofuel crops, 1 ha of photovoltaic cells (counting 10h of production per day, using electrolysis to convert electricity to hydrogen) and the production of hydrogen in one DualTower (using one electrolysis device (1.5MW), counting for 24/7 production over 200 days to account for periods with no wind) over the course of one year.

Energy storage as chemical energy has a much higher energy density than batteries.
