PhD Title: "What is the value of key low-carbon technologies in achieving cost-effective, equitable and sustainable development-consistent mitigation?"

Supervisors: Dr Ajay GambhirDr Tamaryn NappDr Adam Hawkes

I am a PhD candidate based at the Grantham Institute for Climate Change and the Environment, and am part of the 5th cohort of the 'Science and Solutions for a Changing Planet' (SSCP) Doctoral Training Partnership, funded by NERC. My research is focused on understanding the value of different low-carbon technologies in mitigation pathways.

Tackling dangerous climate change will require rapid, far-reaching and unprecedented changes to all areas of society. There are however, a wide range of different low-carbon technologies which could play a role in reducing emissions. Given this need for immediate and significant action, and the wide range of different pathways that policymakers could embark upon, there is a need to better understand the relative value of different low-carbon technologies. This can help policymakers understand what constitutes a 'key' technology or strategy for decarbonisation, allowing R&D funding and policy support to be focused on critical junctures in the energy system.

My thesis focuses on valuing the contribution of key low-carbon technologies to mitigation, by exploring their ability to contribute towards cost-effective, equitable and sustainable-development consistent mitigation. Using energy system modelling tools such as TIAM and the UK TIMES model, as well as non-modelled approaches to futures analysis, I am exploring this question through a set of technology cases studies, including Carbon Capture and Storage (CCS), the Hydrogen Economy, and the falling cost of renewables. I also collaborate with UK policymakers in the Committee on Climate Change and within BEIS, providing analytical support for UK climate policy design.
