“…This expansion will correlate with the availability of fluctuating excess electricity. Power-to-gas (PtG) systems are a suitable technology to convert and subsequently store excess electricity [15]. Gahleitner [16] gives an overview on realized PtG facilities.…”

Global climate change will make it necessary to transform transportation and mobility away from what we know now towards a sustainable, flexible, and dynamic sector. A severe reduction of fossil-based CO 2 emissions in all energy-consuming sectors will be necessary to keep global warming below 2°C above preindustrial levels. Thus, long-distance transportation will have to increase the share of renewable fuel consumed until alternative powertrains are ready to step in. Additionally, it is predicted that the share of renewables in the power generation sector grows worldwide. Thus, the need to store the excess electricity produced by fluctuating renewable sources is going to grow alike. The "Winddiesel" technology enables the integrative use of excess electricity combined with biomass-based fuel production. Surplus electricity can be converted to H 2 via electrolysis in a first step. The fluctuating H 2 source is combined with biomass-derived CO-rich syngas from gasification of lignocellulosic feedstock. Fischer-Tropsch synthesis converts the syngas to renewable hydrocarbons. This research article summarizes the experiments performed and presents new insights regarding the effects of load changes on the Fischer-Tropsch synthesis. Long-term campaigns were carried out, and performance-indicating parameters such as per-pass CO conversion, product distribution, and productivity were evaluated. The experiments showed that integrating renewable H 2 into a biomass-to-liquid Fischer-Tropsch concept could increase the productivity while product distribution remains almost the same. Furthermore, the economic assessment performed indicates good preconditions towards commercialization of the proposed system.

“…Emerging technologies such as liquid air energy storage (LAES) (Morgan et al, 2015;Antonelli et al, 2017;Sciacovelli et al, 2017;Highview Power, 2018), pumped thermal energy storage (PTES) (White et al, 2013;Mctigue et al, 2015;Benato and Stoppato, 2018), and power-to-gas approaches (Belderbos et al, 2015;Mazza et al, 2018) are also under investigation. Georgiou et al (2018) provide a comparison between LAES and PTES also considering the size of plant and further identify the compression and expansion processes, and the associated components (see Mathie et al, 2014;Willich et al, 2017 for a discussion of piston-expander performance), as highly important for overall system performance, while Farres-Antunez et al…”

“…P2G systems can rapidly change their working set point, Polymer Electrolyte Membrane (PEM) electrolyzer can be completely ramped up and down (0÷100% range) in just a few seconds [10]. In order to make the hydrogen react with CO2 and produce SNG, the methanizer must be kept at the working temperature [44,45] and, for simplicity reasons, it was here considered that the methanizer is kept at the correct temperature during operation of the plant with no additional cost or energy consumption.…”

“…In an increased RES penetration scenario, a greater degree of flexibility in the energy dispatch system is required to handle unpredictable variations of energy production and facilitate the RES integration in the existing infrastructures [6]. The key requirements to achieve proper grid operations include a wide range of technologies and solutions, such as energy storage (e.g., Virtual Energy Storage VES [7,8]), energy conversion (e.g., Power-to-Gas (P2G) [9,10] and Power-to-Heat (P2H) [11]), which becomes very important to be able to define appropriate systems of measurement and prediction of energy flows [14] in order to be able to analyze the flexibility potential within energy systems.…”

Renewable Energy Sources (RES) have taken on an increasingly important role in the energy mix in the last few years, and it has been forecasted that this trend will continue in the future. The energy production from these sources is not dispatchable, and the increasing penetration of RES in energy mixes may therefore lead to a progressive loss of generation control and predictability. It has become clear that, to reach higher RES penetration levels, it is essential to increase power system flexibility in order to ensure stable operations are maintained. An ICT (Information and Communication Technology) tool that may be used to manage and optimize the flexibility offered by energy storage and conversion systems is described in this paper with specific reference to the Decision Support System (DSS) developed within the H2020 PLANET (PLAnning and operational tools for optimizing energy flows and synergies between energy NETworks) project. The paper focuses on how the PLANET DSS tool evaluates, manages, and dispatches the flexibility of Power to Gas/Heat (P2X) technologies. Moreover, the tool has been used to analyze a realistic case in order to show how the PLANET DSS tool could be used to evaluate the energy and economic benefits of taking advantage of the flexibility of P2X technologies.Energies 2020, 13, 153 2 of 16 allow flexibility to be increased thanks to interconnections between energy sectors [12,13]. Moreover, energy systems are becoming more and more costumer centric, and in this context it becomes very important to be able to define appropriate systems of measurement and prediction of energy flows [14] in order to be able to analyze the flexibility potential within energy systems.In these scenarios, energy flows within energy systems are somewhat complicated and intricate, due to the interconnection of different energy networks and the increase in stochasticity resulting from distributed generation. For this reason, it is important to have computer simulation tools available to analyze these interconnected energy flows and to evaluate the energy and economic impact of different technologies and regulations on the entire system [15,16].A specific ICT DSS tool has been proposed by The EU-Funded H2020 PLANET project [17] to analyze and optimize the flexibility of P2X energy conversion technologies. The project provides an ICT platform to support network operators/planners, P2X plant managers, load aggregators, and policy makers in order to increase the integration of renewables.Several software programs are available in the literature to simulate energy flows in a Multi Energy System (MES) [16,18,19]. The main advantage of using the PLANET DSS lies in the fact that the tool is built on a web platform: through the web platform, the users can setup and execute a remote simulation, and in this way the various actors can benefit from using a dedicated super-computer for their simulation, to which they would otherwise not have access. Moreover, due to middleware-based communication, Demand-Response (DR) signals ...
