Project at IAS-STS: The Techno-Economics of Renewable Energy Systems; Accelerating Sustainability Transitions Through Policy Mix Design and Cost Optimisation

South Africa is characterised as a country with a high level of per capita emissions, a fragile and inefficient energy system, and a weak economy, all of which make the energy transition an unlikely process unless innovative and affordable solutions can be found.  The goal of the project is to explore low carbon and low-cost options to support the decarbonisation of South Africa’s energy system. The project builds on three overlapping but distinct studies already completed as follows; (1) Policy mixes to support innovation and sustainability transitions (Walwyn and Naidoo, 2019; Walwyn, 2016), (2) Techno-economics of energy systems (Stephens and Walwyn, 2020; Stephens and Walwyn, 2018; Walwyn et al., 2018; Chudy et al., 2015), and (3) Sustainability (energy) transitions in South Africa (Potts and Walwyn, 2020).  This project aligns closely with the focus of the IAS-STS research area on “Towards Low-Carbon Energy and Mobility Systems”, with specific relevance to the objective of shaping policies related to sustainable energy, mobility, climate and technology policies and the mitigation of climate change.
