about the project

The background of RE-INVEST is that nationally and internationally, the focus on renewable energy supply as well as on electricity and gas cross-border interconnections is increasing. Industry, policy makers, TSOs and researchers have traditionally focused on renewable energy integration within one single sector - often electricity only. There is an urgency to move beyond this single-sector or single-technology focus in research, industry and public authorities and look at the transition as a complete redesign of the whole system.

The vision of RE-INVEST is to overcome the silo-thinking that characterizes traditional energy sectors.  Renewable energy prices are decreasing faster and faster in e.g. wind power onshore and offshore, PV, solar thermal etc. Onshore wind power is the cheapest electricity source looking at LCOE, but wind power as well as PV and other renewables depends on domestic and international integration measures such as: power plants stopping (signaled in electricity markets), synthetic gas storage, large-scale heat pumps with thermal storage for district heating, small heat pumps, electric vehicles as well as energy storage and expansion of interconnectors.

RE-INVEST develops novel methodologies for renewable energy investment strategies based on a two-dimensional interconnectivity approach. With key university, industrial, societal and energy investment partners, coherent analyses with state-of-the-art technology and strategy inputs are ensured. Energy system analysis tools combine the Smart Energy System’s cross-sectoral approach using infrastructures, energy storage and savings (electricity, heat and gas) with the cross-border approach.

The project builds on extensive experience with large-scale wind integration studies, use of electrofuels for heavy-duty transport and of cost-effective cross-sector storage options through advanced hourly modelling of all sectors using EnergyPLAN at Aalborg University. Aarhus University’s Network Analyses tool, an advanced method using parametric time series analyses, enables the creation of Pan-European energy systems based on weather patterns. These analyses can balance wind power and PV as well as the need for back-up power plants and international interconnections. In RE-INVEST, the method for combining these two approaches is developed, assisting a cross-border analysis methodology uniting the strengths of both: a total cross-sectoral hourly modelling, weather pattern analyses and an interconnected European system analysis.

From a starting point in a reference model of the current system, potential technology and cost developments in Denmark and Europe are mapped before engaging in use of extensive databases and the partners technology knowledge to construct robust pathways towards 2050. These developments represent different European contexts required in the analyses to establish a strategic decision-making background for energy sector stakeholders.
