Trans-Mediterranean Renewable Energy Cooperation (TREC)

Wednesday, January 9th, 2008

One of the problems with renewable energy is the inflexibility of supply. This inflexibility is the very feature that requires EDM which is the topic of this blog. EDM can only go so far in balancing the supply and demand of electricity. Another technique is to builld supergrids that link broad geographical areas so that meteorological variations can be averaged.

The DESERTEC Concept

In 2003 the Trans-Mediterranean Renewable Energy Cooperation (TREC) was founded by the Club of Rome, the Hamburg Climate Protection Foundation and the National Energy Research Center of Jordan (NERC). TREC in cooperation with the German Aerospace Center (DLR) developed the DESERTEC Concept of linking African, Middle East, and Northern European states electrical grids into one supergrid using high voltage direct current (HVDC) interconnects.

This is a fantastic idea. I recommend you visit http://www.desertec.org to learn more and to register your approval for the project in their ‘Give TREC Your Voice’ campaign.

This is the best video on efficient energy generation and use I have ever seen. I first found it on youtube about a year ago but couldn’t find it again until today when I stumbled across it again.

Google and Vehicle To Grid (V2G)

Wednesday, June 20th, 2007

The work that Google are doing on solar energy and hybrid cars is fascinating. Reading the following blog from Google though adds a new element to the mix.

Google are growing a fleet of plug in hybrid cars. These are standard hybrid cars with larger batteries fitted and the ability to charge from the electricity grid. The blog also mentions vehicle to grid (V2G) technology. This allows the bidirectional transfer of electricity between the electricity grid and the plug in hybrid.

In the context of Ireland’s need to consume surplus wind generated electricity, electric vehicle or hybrid vehicle batteries would be an ideal candidate for energy storage where the stored energy replaced fossil fuels when consumed on the following day. According to the Irish Examiner (19 June 2007), Toyota are selling 400 Prius hybrid cars per annum in Ireland. Obviously the installed base would have to be much higher to have a significant impact on grid stability.
