From 2013 till 2017 we organized several KIVI seminars in Utrecht where more than 50 Dutch professionals presented their views on the energy challenge for the Netherlands in the future. Based on this particularly useful information we devised an energy plan for 2050 and published it beginning 2018.
The plan describes the EnergyNL2050 energy system which is CO2 neutral. The system generates more than 85% of the nationally needed energy and needs at most 15% import from abroad. Although positive feedback was received, we recognized that a few important aspects were still missing, such as hourly based system simulations and a thorough financial analysis.
In this paper we report the results of detailed simulations using hourly weather data, renewable energy production and demand data during three years. Recent functional energy demands (year 2015) were extrapolated to the energy demands expected in 2050. From this the required renewable energy could be analyzed.
THE SIMULATION RESULTS GIVE AMPLE CONFIDENCE THAT THE SYSTEM CAN WORK!
We also refined the system design such that all components cooperate well together to achieve an optimal final result. A detailed financial analysis shows that the EnergyNL2050 system is affordable: the annual energy costs are analyzed to be about €28 billion. The current annual energy costs are about €21 billion. But this cost difference is compensated by the avoided CO2 tax (being €41 per ton CO2) on the 185 Mton saved CO2 emission.
In the implementation care is taken that the Dutch landscape is preserved as much as possible by proposing only a very limited amount of wind power on land and only a very small amount of solar parks.
One important feature also is that the electricity network does not need a significant capacity enlargement by using several interesting techniques such as smart charging, a distributed net of fuel cells, an efficient curtailment strategy and the location of the electrolyzers. The total cost of the system has been modelled and the plan is derived from a total cost optimization of the entire system, including the different segments of the electricity grid.
