Genesis Morocco

Project Genesis is a strategic sustainable development framework for Morocco to translate from being a net importer of energy and a country facing water shortage issues, into the number one producer both of clean renewable energy and water in the region.

Addressing the Energy Storage Question

Using Flywheels. Flywheels ? Yes Flywheels !

The energy generated during peak production time should be stored using flywheels as a means of kinetic energy storage devices. Flywheels have near-zero storage (idling) loss, unlimited service life with no maintenance, ultra-high power conversion efficiency : 95%, allows for minimum deperdition, in that aspect flywheels are superior to any other energy storage technologies.

We are looking at 500Mw capacity flywheels, and we would need 12 such units to store half the production that is 6Gw. That capacity would then be fed to the grid for hours, up to 12 hours allowing us to cover the non peak hours.

Theses units would be situated along the high capacity grid route allowing for efficient delivery to the cities during non peak hours.

Flywheels have the advantage of smoothing out the surges that can result from renewables exploitation either solar or wind based.

With the connection to the EU energy market through high capacity underwater cables in mind, we would also be able to service the EU market during non peak hours.

High resistance materials such as kevlar render this a viable and feasible solution, again the question of technology transfer arises... They where invented by Leonardo da Vinci by the way.

// has got some interesting patents

Patented, pump-free operation

Flywheels spin in a vacuum to minimize aerodynamic drag. Other systems use a constantly operating mechanical pump to maintain a rough vacuum. Instead, Pentadyne’s award-winning systems use a patented molecular vacuum sleeve on the flywheel shaft. The shaft speed combined with the sleeve’s helical grooves maintain the system’s high vacuum (99.9993% evacuated). This eliminates a mechanical point of failure, energy consumption and maintenance/downtime issues related to a continuously operating mechanical pump.

Update 09:30 PM, April 14, 2010: Almost zero deperdition using Hydrogen. Can also be stored for way longer
