Nations around the world require a sustainable energy base to power societies – such as the electricity needed to mobilize vehicles, heat and cool food, and light and heat homes.  However, currently the majority of energy to power the world is made possible through the use of fossil fuels. This provides a challenge to sustainability as the majority of greenhouse gas emissions (GHGs) are generated by the energy sector and by the burning of fossil fuels.    

Renewables, such as wind and solar have important contributions to make toward clean energy alternatives. Yet these technologies may still be decades away from providing reliable and consistent power options on a broad scale. 

As the world needs a reliable energy base, the world needs all the technologies it can get to tackle climate change.  Renewables and CCS are complementary and should co-exist. To underscore the complementary nature, the International CCS Knowledge Centre has done a feasibility design  on the Shand Power Station that is highly flexible for renewable options in a generating mix. This design accommodates the fluctuations in day-to-day operations by adjusting to the variable load changes associated with renewable technologies.  

Until the technological advances are there for renewables to be able to provide reliable, base load energy systems, CCS is an important transitory technology.  Together, renewables and CCS can provide reliable, clean energy solutions.
