“…The present study also confirms individual results of many other studies: the higher benefit of cross-sector coupling compared to cross-border coupling from the two-country study in [37]; the system benefits of district heating [18,92,97,105]; the benefits of centralised heat storage in district heating networks [18,106]; the independence of the benefits of coupling BEV-DSM to the daily cycles of solar PV versus the seasonal storage of energy for the heating sector [93]; the importance of modelling the temperature dependence of the heat pump COP [91]; and the advantages of power-to-gas and methanation in particular in highly renewable energy systems [107].…”

“…In what some authors term 'smart energy systems' [15], demand from, for example, battery electric vehicles or intelligent heating systems can be brought forward or delayed to reduce system costs, and low-cost long-term storage can be provided either chemically, using power-to-gas units to produce synthetic international network bottlenecks are not visible. In one study two countries, Denmark to represent Northern Europe and Italy to represent Southern Europe, were coupled to compare crossborder with cross-sectoral coupling [37]; while both strategies demonstrated benefits, cross-sectoral coupling gave the best performance.…”

There are two competing concepts in the literature for the integration of high shares of renewable energy: the coupling of electricity to other energy sectors, such as transport and heating, and the reinforcement of continent-wide transmission networks. In this paper both cross-sector and cross-border integration are considered in the model PyPSA-Eur-Sec-30, the first open, spatiallyresolved, temporally-resolved and sector-coupled energy model of Europe. Using a simplified network with one node per country, the cost-optimal system is calculated for a 95% reduction in carbon dioxide emissions compared to 1990, incorporating electricity, transport and heat demand. Flexibility from battery electric vehicles (BEV), power-to-gas units (P2G) and long-term thermal energy storage (LTES) make a significant contribution to the smoothing of variability from wind and solar and to the reduction of total system costs. The cost-minimising integration of BEV pairs well with the daily variations of solar power, while P2G and LTES balance the synoptic and seasonal variations of demand and renewables. In all scenarios, an expansion of cross-border transmission reduces system costs, but the more tightly the energy sectors are coupled, the weaker the benefit of transmission reinforcement becomes. (T. Brown) fuels such as hydrogen and methane (so called 'electrofuels'), or thermally [16]. Long-term storage can smooth out both the seasonal variations of renewables and the synoptic variations (∼ 3-10 days in the time dimension).Modelling all energy sectors in high spatial and temporal detail is computationally demanding. In order to maintain computational tractability, previous sector coupling studies have either focused on just a few demand sectors, or sacrificed spatial or temporal resolution.Studies of a few sectors have either considered just electricity and heat, electricity and transport, or electricity and gas. For example, in [17,18] the possibility of using excess renewable electricity in the heating sector was considered, but no requirements were set to defossilise all heating, or to couple to other demand sectors. In another set of studies, a simplified investment and dispatch scheme was used for a one-node-per-country model of Europe to study electricity-heat coupling [19]. Interactions between the electricity sector and transport were studied for electric vehicles in [20][21][22] and including fuel cell electric vehicles in [23,24]. More general coupling of electricity to gas for use in either heating or transport was considered in [25,26].Studies that include multiple sectors, often encompassing all energy usage, but that sacrifice spatial resolution have typically either considered single countries (e.g. Germany [27][28][29][30], , Ireland [34,35]) or considered the whole continent of Europe without any spatial differentiation [36] so that

The literature reports that there are business models that depend on the category of resources and various characteristics of industrialized and developing economies [16][17][18].…”

Renewable Energy in the Electricity Sector and GDP per Capita in the European Union

et al. 2019

Considering that the European Directive has imposed that at least 20% of the total energy should come from renewable energy sources (RES) by 2020 already and the specific targets for each European Union Member State, this paper attempts to assess the importance of GDP per capita in realizing these targets and also the effects of the RES share in electricity. Contrary to previous research, this paper does not consider the connection between economic growth and RES, but rather the potential connection between the share of RES in electricity and the real GDP per capita. The panel data models indicated to a positive, but very low impact of GDP per capita on the share of RES in electricity in the period of 2007–2017 in the case of the EU countries, except Luxembourg that has outlier values of GDP per capita. However, causality between the two variables was not identified. Some groups of countries were described according to these variables using cluster analysis. Future research should focus on the extension of this model by including other important variables such as RES potential available in the countries with specific geographical conditions.

“…Wind and solar power are intermittent resources, but this limit can be overcome through two potential ways: (i) cross-border interconnection and (ii) cross-sector interconnection [11]. The European case study is analysed in the literature and the application of energy storage systems is considered [12].…”

Future Trajectories of Renewable Energy Consumption in the European Union

2018

View full text Add to dashboard Cite

Renewable energy sources (RESs) are able to reduce the European Union (EU)'s dependence on foreign energy imports, also meeting sustainable objectives to tackle climate change and to enhance economic opportunities. Energy management requires a quantitative analysis and the European Commission follows the performance of each Member State (MS) in order to define the corrective measures towards 2020 targets. Starting from historical data reported in the Eurostat database and through a mathematical model, this work proposes future trajectories towards 2020 of the share of energy from renewables (REs) in terms of gross final energy consumption (GFEC). Furthermore, a quantitative analysis based on two indices-(i) the share of REs in GFEC, and (ii) gross final renewable energy consumption (GFREC) per capita-permits a comparison among 28 MSs. The share of REs in GFEC in EU 28 varies from 19.4% to 21.8% in future trajectories towards 2020. Sweden and Finland occupy the top part of the ranking, while six MSs (Belgium, France, Ireland, Luxembourg, The Netherlands, and the United Kingdom) are not able to reach the 2020 targets.
