Abstract


High
shares of renewable energy, particularly wind power, were modelled in several
future scenarios for the Scottish energy system. In the first part of this
work, it was determined that Scotland could produce the equivalent baseload
power for supply to England at a lower overall cost (99 €/MWh) than the
proposed subsidized price (112 €/MWh) to be paid for electricity generated from
the proposed Hinkley Point C nuclear power plant. This cost includes all extra
generation capacity and transmission lines. In the second part of this work, it
was determined that a 100% renewable energy system could be achieved at an
annualized cost of 10.7 b€/a, approximately 8% less than the 11.7 b€/a expected
for an energy system comprised of 75% renewable energy. In the 100% renewable
energy system, cost savings are achieved through effective energy storage,
sector integration, and flexible generation from dispatchable renewable energy
resources, such as hydropower (1.7 GWe), bioenergy, and synthetic
fuels. Complementary resources to 23.4 GWe of wind power also
included solar photovoltaics (10.1 GWe), tidal power (1.5 GWe),
and wave power (0.3 GWe). It was also determined that carbon capture
and utilisation would be a preferable strategy to carbon capture and storage
for Scotland. Complete defossilisation of the Scottish energy system appears
feasible by 2050, given the assumptions used in this study.
