The UK government has established ambitious policies to address climate change and promote renewable energy, and has set targets both for reducing carbon emissions and for deploying renewables. Scotland, a constituent nation of the UK, has also set its own targets for climate change mitigation...

Climate change and energy security are forcing Hong Kong to shift from a fossil fuel-based to a clean and low-carbon energy structure. In this article, a simulation model for Hong Kong's energy system is developed to examine the present energy structure and analyse alternative future sustainable...

In Hungary, there is a need for detailed alternatives to its fossil-based, highly import-dependent energy system. In this paper, an energy model of the Hungarian energy system of 2009 is worked out, as a reference model for a 100% renewable-based scenario. The model is created in the EnergyPLAN...

Integrating a high share of electricity from non-dispatchable Renewable Energy Sources in a power supply system is a challenging task. One option considered in many studies dealing with prospective power systems is the installation of storage devices to balance the fluctuations in power...

The city of Pécs in Hungary has developed an energy strategy to be implemented in the years to come which proposes structural changes in both the supply and demand sides. This paper offers a model based on the proposed system aimed at providing a basis for comparison for decision-makers. The...

EH (excess heat) is an important, but yet partially unused, source for DH (district heating). This study analyses energy system and CO2 emission impacts at a regional scale of integration of EH from a large chemical cluster and local DH systems. The assessment is carried out with the optimising...

This paper estimates the impact on Belgium of the EU climate policy. This policy intends to reduce the emissions of EU greenhouse gases (GHG) by 80% in 2050 compared to 1990 emissions. The EU target was distributed over member countries in a cost effective way with the European TIMES model and...

This paper uses a whole-system approach to examine different strategies related to the future role of the gas grid in a low-carbon heat system. A novel model of integrated gas, electricity and heat systems, HEGIT, is used to investigate four key sets of scenarios for the future of the gas grid...

Germany must decarbonise all energy sectors to meet international and national climate goals. This task necessitates linking the electricity with the gas, heat and mobility sectors. On the one hand, sector coupling increases the demand for electrical energy and changes well-known demand patterns...

Energy system models provide us with scenarios for the future energy system, supporting our understanding of the impact of societal changes and adopted policies. To front-load the EU'Fit for 55' package for 2030 and targets of replacing imported natural gas with renewable electricity, the Nordic...
