Transition towards long-term sustainable energy systems is one of the
biggest challenges faced by the global society. By 2050, not only
greenhouse gas emissions have to be eliminated in all energy sectors:
power, heat, transport and industry but also these sectors should be
closely coupled allowing maximum synergy effects and efficiency. A tool
allowing modelling of complex energy system transition for power, heat,
transport and industry sectors, responsible for over 75% of the CO2eq
emissions, in full hourly resolution, is presented in this research and
tested for the case of Kazakhstan. The results show that transition
towards a 100% sustainable and renewable energy based system by 2050 is
possible even for the case of severe climate conditions and an energy
intensive industry, observed in Kazakhstan. The power sector becomes
backbone of the entire energy system, due to more intense
electrification induced sector coupling. The results show that
electrification and integration of sectors enables additional
flexibility, leading to more efficient systems and lower energy supply
cost, even though integration effect varies from sector to sector. The
levelised cost of electricity can be reduced from 62 €/MWh in 2015 to 46
€/MWh in 2050 in a fully integrated system, while the cost of heat
stays on a comparable level within the range of 30–35 €/MWh, leading to
an energy system cost on a level of 40–45 €/MWh. Transition towards 100%
renewable energy supply shrinks CO2eq emissions from these sectors to zero in 2050 with 90% of the reduction achieved by 2040.
