The transition to low carbon future requires interim measures which allows the integration of renewable energy sources into existing systems and the development of new technology that integrate the new and the old. This approach is needed because of the intermittent nature of renewable energy, the cost of energy storage, and the need for firm supply by all consumers, especially industry. The hybrid approach helps in the cost effective integration of renewables and provides the certainty that industry needs. This talk will focus on the integration of renewable energy in the heavy industry sector and will provide examples where concentrated solar thermal and combustion can be integrated to decarbonize these energy intensive processes in a cost effective manner.
