One of the themes I write about most often on this blog is the shift from fossil fuels to renewables. Today I will write about two very big solar projects that are currently being built, one in Egypt and the other in Dubai.
The Benban Solar Park is a huge development in southern Egypt, where they are building a 1,650 MW power station entirely with photovoltaic panels. Interestingly the project is made up of 41 varying sized units, each being built by different companies from all around the World. The first unit started feeding electricity into the grid in March 2018, and the others will rapidly follow over the next couple of years. There are 10,000 people currently working on the site, and for many of these people it is the first period of continuous work they have ever had, having previously been day labourers. This helps lift them out of poverty and also get more skills and training. (Also see IFC on Benban)
One of the interesting aspects of Benban is that, as far as I can see, it has no on-site energy storage. However it is not very far from the Aswan Dam. The two projects could be used in tandem, with water held back in the day time while Benban is producing solar electricity, then the hydro turbines could be opened to full in the evenings to match demand. In the longer term, as Egypt develops lots more solar energy the Aswan Dam could also be converted into a pumped storage hydro facility.
In Dubai the Mohammed bin Rashid Al Maktoum Solar Park is currently being built in phases, the first of which came on stream in 2013, a small first step with just 13 MW of solar photovoltaics. Subsequent stages are each much bigger, and by 2030 they anticipate the whole planned 5,000MW plant will be operational. The fourth phase contracts have just been signed for 700MW of concentrating solar thermal power, made up of three 200 MW parabolic troughs and a 100MW central power tower. The whole system will have up to 15 hours of thermal energy storage, probably in the form of molten salt. This will mean that this solar park will be able to supply reliable electricity night and day to Dubai. Each successive phase of this solar project has seen the price of power come down as the technology continues to improve.
Many countries are now rapidly ramping up their use of solar power. The global transition from ‘The Fossil Fuel Age’ to ‘The Solar Age’ is underway. Whether humanity makes this transition fast enough to escape the worst ravages of climate change will be one of the prime determinants of our collective future as a species. Bring on ‘The Solar Age’!
