“…They are used to illuminate general tendencies and hence necessarily simplify complex phenomena, but, on the other hand, are able to run on computers with limited capacities. Such simplifications could include, for example, The model environment used (see Section 2) will give researchers an approach and a methodology for conducting similar analyses in different countries, such as that which was already conducted by Guandalini et al (2017) [7]. As the focus of the literature review in Part 1 [1] was on Germany and the model environment is based on this country, a SC scenario for Germany will be developed.…”

Linking the Power and Transport Sectors—Part 2: Modelling a Sector Coupling Scenario for Germany

et al. 2017

"Linking the power and transport sectors-Part 1" describes the general principle of "sector coupling" (SC), develops a working definition intended of the concept to be of utility to the international scientific community, contains a literature review that provides an overview of relevant scientific papers on this topic and conducts a rudimentary analysis of the linking of the power and transport sectors on a worldwide, EU and German level. The aim of this follow-on paper is to outline an approach to the modelling of SC. Therefore, a study of Germany as a case study was conducted. This study assumes a high share of renewable energy sources (RES) contributing to the grid and significant proportion of fuel cell vehicles (FCVs) in the year 2050, along with a dedicated hydrogen pipeline grid to meet hydrogen demand. To construct a model of this nature, the model environment "METIS" (models for energy transformation and integration systems) we developed will be described in more detail in this paper. Within this framework, a detailed model of the power and transport sector in Germany will be presented in this paper and the rationale behind its assumptions described. Furthermore, an intensive result analysis for the power surplus, utilization of electrolysis, hydrogen pipeline and economic considerations has been conducted to show the potential outcomes of modelling SC. It is hoped that this will serve as a basis for researchers to apply this framework in future to models and analysis with an international focus.

“…The driving forces for these technologies are the increasing penetration of smart grid technologies, the growth in VRE generation, and the emerging markets for ancillary services . RES integrated biorefineries are a possible long‐term and large‐scale storage solution for VRE . The proposed concepts and demonstrations most commonly involve integration of either biogas or syngas with electrolytic hydrogen.…”

This paper surveys the status and future prospects of bioenergy renewable energy source (RES) hybrids, i.e. energy conversion processes that have at least two renewable energy inputs, one of which is bioenergy. Finland, Austria, Germany and Denmark were the case study countries. We found that the implementation of bioenergy RES hybrids was already ongoing in various sectors, but a majority of them was focused on domestic heating applications. Bioenergy can be used to provide flexible resources for both energy supply and energy storage. An important motivation behind hybrid systems is the possibility of switching between different energy sources in an optimal way. No significant technical limitations were identified for surveyed hybrid systems, but the future economic potential of bioenergy RES hybrids remains difficult to estimate as the value of flexibility cannot be assessed in isolation from the energy system.

“…As of 2015, the Italian power generation sector (i.e., 120 GW capacity) included in its annual generation (i.e., 317 GWh) 58% thermal power, 14% hydroelectricity, 7% solar, 4% on-shore wind, and 2% geothermal, with the rest of the demand met through electricity imports [82]. The geographical shape of the country restricts the implementation of a meshed electricity grid in central geographical areas, and would affect the potential of energy storage technologies.…”

“…Guandalini et al [82] assessed the power-to-hydrogen potential from on-shore wind and solar PV in the Italian 2050 energy system. Wind and solar PV capacities of 9 to 49 GW and 19 to 98 GW, respectively, in conjunction with annual demands of either 290 or 350 TWh, were assumed in five different future energy scenarios.…”

Technical, economic and environmental assessments of projected power-to-gas (PtG) deployment scenarios at distributed-to national-scale are reviewed, as well as their extensions to nuclear-assisted renewable hydrogen. Their collective research trends, outcomes, challenges and limitations are highlighted, leading to suggested future work areas. These studies have focused on the conversion of excess wind and solar photovoltaic electricity in European-based energy systems using low-temperature electrolysis technologies. Synthetic natural gas, either solely or with hydrogen, has been the most frequent PtG product. However, the spectrum of possible deployment scenarios has been incompletely explored to date, in terms of geographical/sectorial application environment, electricity generation technology, and PtG processes, products and their end-uses to meet a given energy system demand portfolio. Suggested areas of focus include PtG deployment scenarios: (i) incorporating concentrated solar-and/or hybrid renewable generation technologies; (ii) for energy systems facing high cooling and/or water desalination/treatment demands; (iii) employing high-temperature and/or hybrid hydrogen production processes; and (iv) involving PtG material/energy integrations with other installations/sectors. In terms of PtG deployment simulation, suggested areas include the use of dynamic and load/utilization factor-dependent performance characteristics, dynamic commodity prices, more systematic comparisons between power-to-what potential deployment options and between product end-uses, more holistic performance criteria, and formal optimizations.
