The reliable supplies of electricity and hydrogen required for 100%
renewable energy systems have been found to be achievable by utilisation
of a mix of different resources and storage technologies. In this
paper, more demanding parameter conditions than hitherto considered are
used in measurement of the reliability of variable renewable energy
resources. The defined conditions require that supply of baseload
electricity (BLEL) and baseload hydrogen (BLH2) occurs solely
using cost-optimised configurations of variable photovoltaic solar
power, onshore wind energy and balancing technologies. The global
scenario modelling is based on hourly weather data in a 0.45° × 0.45°
spatial resolution. Simulations are conducted for Onsite and Coastal Scenarios from 2020 to 2050 in 10-year time-steps. The results show that for 7% weighted average cost of capital, Onsite BLEL can be generated at less than 119, 54, 41 and 33 €/MWhel
in 2020, 2030, 2040 and 2050, respectively, across the best sites with a
maximum 20,000 TWh annual cumulative generation potential. Up to 20,000
TWhH2,HHV Onsite BLH2 can be produced at less than 66, 48, 40 and 35 €/MWhH2,HHV,
in 2020, 2030, 2040 and 2050, respectively. A partially flexible
electricity demand at 8000 FLh, could significantly reduce the costs of
electricity supply in the studied scenario. Along with battery storage,
power-to-hydrogen-to-power is found to have a major role in supply of
BLEL beyond 2030 as both a daily and seasonal balancing solution.
Batteries are not expected to have a significant role in the provision
of electricity to water electrolysers.
