Myth of technical un-feasibility of complex multi-terminal HVDC and ideological barriers to inter-country power exchanges – Czisch

From Dr Gregor Czisch.

There are two subjects in Nigel Wakefield’s email I would like to address:

First Subject- Technical feasibility of complex multi-terminal HVDC systems:

Can anyone elucidate on this?

European Super Grid – "Wrong to suggest this would make Europe more vulnerable than importing Russian Gas and Middle East fossil fuels" – ?

The above slide from Czisch (“An affordable renewable power system for Europe”) shows that Europe is unlikely to be vulnerable to sudden disconnection / sabotage of say a single or several, North African regions since there is considerable redundancy in connection and diversity of supply areas, and European grids of necessity already have existing sophisticated […]

Physics and Engineering Basis of Multi-functional Compact Tokamak

Kindly provided by Brendan McNamara.  Part of the IAEA Fusion Conf Proceedings at Geneva this Oct.  Basically small fusion reactors are viable now. Abstract An important milestone on the Fast Track path to Fusion Power is to demonstrate reliable commercial application of Fusion as soon as possible. Many applications of fusion, other than electricity production, have […]

New Study Puts The Generation Costs For Power From New Nuclear Plants Triple Current U.S. Electricity Rates

A new study puts the generation costs for power from new nuclear plants at 25 to 30 cents per kilowatt-hour — triple current U.S. electricity rates.

Current CSP costs (still substantially less than nuclear):
Vinod Khosla gives current CSP at 16 cents kWh (and note PV far higher at 22.4 cents kW/hr – see slide 124 onwards at http://www.slideshare.net/guest76ed37/khosla92507 rel=no follow
Also, good summary of costs can be found here: puts current CSP at 13 – 17 cents kWh: http://peakenergy.blogspot.com/2008/04/concentrating-on-important-things-solar.html/ rel=no follow
Makes CSP look very attractive indeed at 11 cents per kWh by 2011 (cf Ausra & Bright Source CSP plants signed up with PG&E in South West America) – compatible with gas prices, and estimated to reduce to 4-6 cents per kWhr by 2020. Nuclear costs unlikely to reduce, but instead are on an upward trajectory.
