... In this process, water is split into O 2 and H 2 by an electric current. If the electric current comes from renewable sources, the hydrogen produced is called green hydrogen [29,30]. ...
... The framework (Fig. 1) lists the main pillars of PED creation and PED guiding principles (either side of the figure) which can be linked to justice aspects most at risk for energy vulnerable people. In terms of renewable energy production, this can be associated with affordability given that operating costs for RES are significantly lower after installation ( [15]), and savings may be passed on to residents, thus connecting to the PED principle of inclusiveness. Inclusiveness is linked to the affordability of housing, energy supply and energy retrofitting for residents in the PED. ...

... The uncertainty associated with the inputs during times of crisis is also highlighted by researchers such as Liu [64] or Muir [65], but that uses the WACC indicator to evaluate companies. The importance of this indicator is essential during this period (WACC being used as the discount rate for cash flows), considering the need to (1) re-evaluate the companies, both for reconfiguring the restructuring plans and for preparing the companies for possible takeovers and to (2) revise the investment plans [34,56,59,[66][67][68][69][70][71][72][73][74][75][76][77][78][79][80]. The companies in the field of energy face, on the one hand, technical challenges that are generated by the need to produce energy from renewable sources and, on the other hand, difficulties induced by political risk [59,[68][69][70][71][72][73][74][75][76]. ...
... However, they cannot supply electricity on demand, and this hinders their value (Braff et al., 2016;Gupta et al., 2020;Parra and Patel, 2019). Storage technologies can provide flexibility, increase the value of renewable energy technologies, and accelerate their penetration to reach net-zero decarbonisation (Gupta et al., 2020;Ziegler et al., 2019;Schill, 2020;Haas et al., 2022). ...
... For the purpose of answering the research question defined above, a stochastic dynamic program with a look-ahead policy is developed. The model is based on the bi-level optimization model presented by the authors in [33], which is able to select optimal new members for an energy community while simultaneously optimally allocating the PV generation between the members considering their individual willingnessto-pay. In this paper, that model is further developed such that the decision made here and now includes a time horizon peaking into the future. ...
... The capital intensity of the industry, coupled with declining return on invested capital, represents another important consideration for potential investors. The energy transition from fossil fuels to renewable energy [29] can help boost the degree of competition in the medium term as new large actors are likely to emerge on the market, assuming that fast-growing companies possessing the necessary technologies are not quickly taken over by industry incumbents to prevent shifts in market power. In order to benefit from energy transition and make the energy market more competitive, regulatory authorities should try to support or elaborate mechanisms which would help young and fast-growing alternative energy companies remain viable without the need for takeover by large industry incumbents. ...
... The study presented in [18] shows the environmental and economic benefits of establishing a REC and discusses the potential of renewable energy communities for fifth-generation district heating and cooling systems. In a different study, S. Zwickl-Bernhard et al. [19] proposed the decarbonization of an urban district of Vienna through two different linked approaches that allow the almost complete electrification of energy services and involve the expansion of the district heating network. ...
... This action plan has led to various other initiatives across Europe (e.g., Making City [3], +cityXchange [4], IEA EBC Annex 83 (International Energy Agency's Energy in Buildings and Communities programme) [5] and Pocityf [6]). In academia, PED-based research has also been increasing [7][8][9]. PEDs have been developed using different approaches and techniques from different actors. According to the Joint Programming Initiative (JPI) Urban Europe [10], there were two operating PEDs at the beginning of 2020, with 19 others in the implementation stage and 8 in the planning stage. ...
... The one-way centralized energy system has high power transmission and distribution loss and risk of grid overheating accidents. Due to manual monitoring, hardly pinpointed the fault which leads to transmission loss and frequent power outages and requires high restoring time, and creates economic harm and losses [29]. ...
