Energy storage becomes a necessity when a high penetration of renewable energy sources is desirable. Variability in the energy production from these types of energy sources can make the utility grid unstable, if the percentage of production is important. In order to minimize this problem, the HiDRENER project was designed to study the effect of combining different renewable energy sources with energy storage on grid stability. The system has a wind generator, a gasifying biomass power plant with syngas storage, a solar photovoltaic plant, and a hydrogen energy buffer. Controlling the entire system is very complex. This paper shows the results of the grid-connected hydrogen energy buffer characterization, considering hydrogen production in this first stage. The objective is to know the complete behavior of the system, which could help us to define the energy buffer control. This control is oriented toward consuming excess energy produced by the other sources in real time. This means that the hydrogen buffer control has to negotiate how much energy can be stored, and act on the production system. Thus, actuation variables and dynamic behavior have to be discovered. Dr. E.A. Veziroglu Editor-in-ChiefInternational Journal of Hydrogen Energy The article that I send to be considered for its inclusion in your publication presents the results of an experimental characterization study done to a grid connected hydrogen production system that is part of a complete project, named HiDRENER. The HiDRENER project was designed to study the effect of combining different renewable energy sources with energy storage on grid stability. The system has a wind generator, a gasifying biomass power plant with syngas storage, a solar photovoltaic plant, and a hydrogen energy buffer. The hydrogen production system takes part of the hydrogen energy buffer. The objective is to know the complete behavior of the system, which could help us to define the energy buffer control. This control is oriented toward consuming excess energy produced by the other sources in real time. Thus, before we designed the control system, we need to know the complete behavior of production system. This work is the natural continuation of last papers that we published in your publication, titled Wind park reliable energy production based on a hydrogen compensation system. Part I and II. There, we showed the results of the system simulation. Now, we show first results of experimental implementation.Thank you very much in advance for your time. Sincerely yours Carlos Sánchez-DíazCover Letter Dear Dr. Muradov, We want to thank the reviewers their comments that, we are sure, will improve the quality of the paper, even if they consider that it is not able to publication. Below we show their comments and we describe the modifications made to the original document we sent. If no modification is made, we justify why. Reviewer #1:This paper is generally well written, but another check is required: for example, figure 8, 9, 11, 13, 14, 15 present words in Spanish ...

“…No solar thermal plant is installed, but it might be if the heat supply options were operated in series rather than in parallel as in this case, and 37% of the electricity demand is directly met by the PV unit as no electric storage is employed. As in the case of Marino et al (2013), the systems are somewhat over-dimensioned in order to ensure security of supply even on the coldest days of the year, and Milan et al (2012) do not investigate the application of a mCHP and/or battery to such a building.…”

“…One technological option is to convert electricity into hydrogen through electrolysis and then store the hydrogen to be later used for cogeneration of heat and power in a fuel cell. Marino et al (2013) carried out an environmental, economic and energy analysis of such a system in three specific configurations, namely in combination with a wind turbine, a PV module, and both, for a public building. In both cases the renewable plants are dimensioned in order to enable an off-grid operation, which means at times of low renewable generation and high demand, this whole demand should be met from the hydrogen storage and fuel cell.…”

Energy autonomy in residential buildings: A techno-economic model-based analysis of the scale effects

2017

An increasingly decentralized energy supply structure alongside economic incentives for increasing the level of self-generation and -consumption are encouraging (higher levels of) energy autonomy. Previous work in this area has focused on the technical and economic aspects of energy autonomy at distinct scales, from individual buildings, through neighbourhoods to districts. This paper employs a mixed integer linear program (MILP) to assess the effects of aggregation across these scales on the economics of energy autonomy in residential buildings. The model minimizes total energy system costs over the lifetime of the energy system, including micro-CHP, PV, thermal and electrical storage, and boilers, at five distinct scales and for nine demand cases. It is subject to several constraints, amongst other things the degree of electrical self-sufficiency. The results indicate a shift in the economically optimal level of electrical self-sufficiency with scale, which in Single Family Households (SFHs) means from around 30% at the individual building level to almost 100% in districts of 1000 SFH households. Above around 560 households it could be economically advantageous to make a district of residential buildings electrically self-sufficient. In addition, a marginal increase in electrical self-sufficiency is significantly more expensive at lower aggregation scales (i.e. single buildings) compared to the scale of neighbourhoods and districts. The level of interaction with the electrical distribution network increases with increasing electrical self-sufficiency before then decreasing at very high (above 70%) levels. Future work should focus on a richer socioeconomic differentiation, considering other sectors and technologies, incorporating demand side options and analysing the effects on the overarching energy system.

“…Hence, Díaz Lobera & Foley [12] examined the impacts of a compressed air energy storage facility in a pool based wholesale electricity market in a power system with a large renewable energy portfolio, while Marino et al [13] analysed energy, economic and environmental aspects of a self-sufficient system for energy production in buildings which uses hydrogen for energy storage.…”
