DESCRIPTION:As a society we are highly reliant on fossil fuels\, and while
  in recent years great advances have been made in renewable ways to genera
 te electricity our ability to store this energy is lagging behind. One way
  to store this energy is in the form of chemical fuels that can be easily 
 interfaced with our current energy storage and distribution networks. A gr
 eat amount of attention has been paid to the development of better perform
 ing catalysts for the production of fuels from waste products such as CO2\
 , however even the best systems are still being comfortably outperformed b
 y nature that has had millenia to develop enzymes with exceptional selecti
 vities and activities for fuel forming reactions. The study of these enzym
 es can provide inspiration for the next generation of synthetic fuel formi
 ng catalysts\, but they also act as an excellent model system for understa
 nding how these ideal catalysts of the future might perform in a system. B
 y performing a catalytic reaction the local environment surrounding a cata
 lyst is inherently different to that of the bulk solution\, to understand 
 how this affects the performance of the system as a whole\, a CO2 reducing
  enzyme (Formate Dehydrogenase) was immobilised within a porous electrode 
 surface and the local environment surrounding the enzyme resolved by combi
 ning electrochemical experiments with computational (finite element) model
 ling. In this talk I will discuss the effect of the local environment on t
 he performance of enzymatic catalysts\, and how this environment can be op
 timised by solution design and enzymatic control to give the best overall 
 performance of the system as a whole. A factor that is commonly overlooked
  when designing electrocatalytic systems.
