p7: Do you know when will the "Desert Power 2050: Getting Started" be published?
p11: Do you know to what extent EU governments have negotiated with MENA suppliers (and vice versa) a price structure?
The governments do not have to negotiate. It's private investors that will bilt the power plants and they will sell it on the market. Government could make some FIT, but so far this i not planned (in Europa for MENA electricity)
p12: It was interesting to me to see that half of the supply will come from wind and a quarter from solar. Do you think this mix could change by 2050? Can climate (wind) be predicted for 2050? They mentioned on p35 that geothermal and marine might play a larger role by 2050. Maybe even solar too.
It already changes to a higher degree of PV. So far petrothemal geothermal energy is ultra-expensive, mich cheaper hydrothermal geothermie is possible only in very small amounts.
The biggest problems in the cost forecast figures should be offshore wind and CSP technologies.
p13: How far has grid extension planning/construction progressed?
There is one small libe bewtween Marocco and Spain, but it was built before Desertec. There is also the NorNED cable ind the Noth and NorLINK will be built soon. Theer are plans for some large power plants in Marocco and another cable from Marocco to Spain.
p14: We know this region (esp MENA) is politically unstable. Can supply really be secured in this environment? Perhaps by 2050, these countries will be relatively stable and democratized.
They have been stable enough to buy oil and gas from them.
p18: Has this document been shared with utilities/governments in member countries? Scenarios mentioned on p56 may be of interest to them.
p36: Considering historical price volatility (p59), why bother considering fossil fuels?
The last 10% are the most expensive.
You wouldn't have to pay for carbon emissions either. At least eliminate coal. Can central Europe use another power source besides gas (p68)? This will likely gradually decline anyway as supply dwindles.
Methane could have much more uses besidespower plants and it could be made out of electricity and or biomass
p40: Storage technologies may also be quite different by 2050. Don't need gas insurance (p97), electricity can be stored.
Super cheap batteries will not change the scenario. Not any options for long term storage are available. ringwall storage systems are an example. you have to start to build them now to have them available in 2050. http://www.dlr.de/blogs/en/desktopdefau ... _read-271/
p69: Are there any contingencies for disruption of power supply when transmission lines are broken?
Maybe we should talk about this in 10 or 20 years.
p104: Can all countries concerned be persuaded to adopt the cheapest Low Demand Connected scenario?
I doubt that we will see any low demand scenario without expensive energy prices. As long as energy is cheap, demand will raise.
But it is not neccessary to have a low demand scenario, there is plenty of solar and wind potential in MENA region to power not only the electricity sector, but also to heat industrial prcesses and buildings and to use it for mobility.
