What is Concentrated Solar Power and how does CSP work?
Despite the many benefits of CSP, it does have its downsides. For one, it''s largely dependent on location. Similar to solar PV and wind power, CSP plants require a large area of land to operate, which makes it uneconomical in populated areas. Concentrated solar power uses a lot of water to drive steam turbines and to cool thermochemical reactors.
6 FAQs about [Concentrating solar power Tokelau]
Can Tokelau support itself with solar energy?
Tokelau, an island nation in the South Pacific, is now completely able to support itself with solar energy. Elly Earls met Joseph Mayhew of the New Zealand Aid Programme to find out how this tiny collection of atolls has become almost 100% self-sufficient in less than 12 months.
How much electricity does a solar system provide in Tokelau?
Each system alone is among the largest off-grid solar power systems in the world, and together they are capable of providing 150% of current electricity demand in Tokelau, a much higher amount than the 90% that was originally planned for.
Could Tokelau be the world's first renewable nation?
Solar power plants and coconut biofuel-powered generators switched on in Tokelau has made the islands the world’s first truly renewable nation.’ Imagine a place where the only energy to be found is clean, reliable solar power. Solar Array’s seen on the three tiny islands of Tokelau to completely produce solar power energy.
Why did Tokelau switch to solar?
Yet despite the challenges involved in installing comprehensive solar systems in such a remote location, switching to solar was absolutely crucial for the tiny collection of islands. "Tokelau’s atolls are low-lying and especially susceptible to the adverse effects of climate change," Mayhew stressed.
Why is electricity so expensive in Tokelau?
Before the PowerSmart systems were installed on the nation’s three atolls, Tokelau was highly dependent on imported fossil fuels to meet its energy needs and therefore vulnerable to international price fluctuations and increasing fuel costs, making electricity extremely expensive for both households and businesses.
How much does a diesel generator cost in Tokelau?
Indeed, until recently, diesel generators were burning around 200 litres of fuel daily on each atoll, meaning more than 2,000 barrels of diesel were used to generate electricity in Tokelau each year, costing more than $1m NZD.
