COP21 a historic milestone
Universal agreement on:
“GHG emissions peak asap”
Stay “below 2°C” temperature increase, get close to 1.5
Reach “carbon-neutrality” in second half of this century
Renewables around COP21
Renewables explicitly referred to in around 100 pledges
Record renewable capacity additions in 2014 and 2015
Lowest-ever announced wind and solar prices
Downturn in prices for all fossil fuels
Oil & gas set to face a second year of falling upstream investment in 2016
Coal prices remain at rock-bottom as demand slows in China

Onshore wind Solar PV - residential Solar PV - utility scale
Innovation and scale-up are driving costs down
High levels of incentives are no longer necessary for solar PV and onshore wind, but their economic attractiveness still depends on regulatory framework and market design

Where CST fits in the picture
1. Generate dispatchable electricity
2. Provide high-temperature industrial process heat
3. Manufacture energy vectors as « solar fuels »

Complementary roles of PV and STE

Thanks to thermal storage, STE is generated on demand when the sun sets while demand often peaks and value of electricity increases

… value matters as much!
Ten years ago, LCOE of CST power was half that of PV
Now, the reverse holds true
CST power will not beat PV on costs, but compares withPV + storage
Time-of-delivery payments reflect the true value of storage
CST Power was born in the 1980s in California thanks to time-of-delivery energy and capacity payments
CST is being developed in South Africa thanks to a x2.7 multiplier of Base Price during 5 hours a day

In sum…
CST is being challenged by PV but will have an important role to play in power systems thanksto built-in storage
CST heat, alone or with RE power, can
• substitute fossil fuel use in many industries, avoidingenergy (and possibly process) CO2 emissions
• manufacture CO2-free hydrogen and energy vectors
CST will be needed to reach carbon-neutrality in second half of the century and stay below 2°C temperature change
