100% Renewable Energy Transport Scenarios towards 2050

The transition from fossil fuels toward integration of more and more renewable energy requires rethinking and redesign of the energy system. The paper launches the design of Smart Energy Systems through the 100 % renewable energy system analyses and research behind the CEESA research project.

The hypothesis is that heavy integration of the different sectors using energy will create the most fuel efficient and low options for 100 % renewable energy and transport systems.

Traditionally a lot of focus internationally is put on the electricity sector to solve the integration puzzle focusing on electricity storage technologies e.g. batteries, hydrogen storage and on (electricity) smart grids. In Smart Energy Systems the focus is integration of the electricity, heating and transport sectors, and on using the flexibility in demands and various short term and longer term storage in the different sectors. Such a redesign also entails that the Smart Energy System is comprised of a number of smart grid infrastructures for different sectors in the energy system, i.e. the electricity grids, district heating (cooling) grids, gas grids and fuel infrastructure.

IDAs Energivision 2050

IDAs Energivision 2050 er et bud på et robust og fleksibelt dansk energisystem, som bygger på vedvarende energikilder og et massivt fokus på energibesparelser. Visionen er baseret på et effektivt energisamspil på tværs af sektorer som industri, boliger, transport og husholdninger.

IDAs Energivision 2050 bygger videre på arbejdet i Ingeniørforeningens Energiplan 2030 og IDAs Klimaplan 2050, som udkom i henholdsvis 2006 og 2009. Visionen er baseret på bidrag fra en række af IDAs fagtekniske netværk samt Aalborg Universitets mangeårige arbejde med energisystemanalyse.

Currently most energy systems are predominantly based on fossil fuels. More and more focus is being placed on energy savings, renewable energy and handling intermittent resources as the shares of fluctuating resources increase. In the current fossil based system, the flexibility is based on the fuels provided for power plants, boilers and vehicles in liquid, gas, and solid form.

Current system have built up the infrastructure and storage facilities that can provide for the demands by means of transporting fossil fuels over large distances in ships and gas pipelines on the global level and providing national or regional energy infrastructure, gas and oil storage facilities and electricity production.

Hence a global system is built up based on the easy storage and density of fossil fuels that can flexibly provide for the demands at the right time and place. While this is the case now, the challenge is how such flexibility and timely energy supply can be provided with more and more renewable energy?

Our hypothesis is that heavy integration of the different sectors using energy will create the most fuel efficient and low options for 100 % renewable energy and transport systems. In this paper we lunch the design of Smart Energy Systems for 100 % renewable energy by highlighting the key components in such systems.

We used concrete smart energy system design from the strategic research project CEESA (Coherent energy and environmental system analyses) as the case to illustrate such design. In the project we have conducted analyses of 100 % renewable energy and transport system designs. It should be noted that there can be many other scenarios using the Smart Energy System design highlighted in this paper.
