Sustainable Energy Market Integration

Denmark has set an ambitious long-term climate and energy targets that eliminating fossil fuel for all energy sectors by 2050. Developing towards this target, the energy sector is facing the challenges to providing reliable, flexible, and price-competitive energy services to communities. And with the development and deployment of innovative, sustainable low-carbon energy technologies, the interdependence of different energy carriers such as power, gas and heat has been continuously enhanced. The integrated approach is promising to accommodate the growing share of renewable energy.

Energy system integration, a renovation of existing energy systems to ensure the optimal interoperability across among electricity, natural gas, heating/cooling, transportation, etc., has drawn broad interests. Energy system integration can provide the electrical system with more flexibility from the network perspective. And hence more variable renewable generation can be accommodated. Meanwhile, the storages in different systems e.g. electrical, gas and heat could be further coped with each other. Existing utility-scale electrical energy storage (EES) excels in high efficiency, fast response and easy connection to the system while the gas/heat storage tanks are more cost-effectiveness and with higher energy density.

The project is to investigate the future integrated energy system from the market perspective.
