  • Investigation of Heat Pump Efficiency in Baltic States Using TRNSYS
           Simulation Tool

    • Abstract: A heat pump is one of the most popular energy transformation devices to provide the building with the necessary heating and cooling energy during the cold and warm seasons. Air source heat pumps (ASHP) in building heating and/or hot water systems are becoming more and more attractive these days because they can use renewable energy as an energy source instead of fossil fuels and thus contribute to the fight against climate change. By using an evaporator heat exchanger, ASHP takes the low-potential heat from the ambient air and transforms it into higher-potential heat for building heating and/or hot water preparation. The main problem with this type of energy transformer is the freezing of the evaporator at high outdoor humidity and a temperature close to 0° C when the condensed moisture of the ambient turns to frost on the surface of the evaporator heat exchanger. This phenomenon significantly reduces the efficiency (COP) of the ASHP. Thus, its performance strongly depends on the climatic conditions of the environment in which it operates. This study presents a numerical model of the heat pump under investigation developed with the TRNSYS software. The type of heat pump used in TRNSYS has been adjusted according to the heat pump characteristics provided by the manufacturer. The validated model is used to model the heating system of a building in the three Baltic States. Modeling results under different climatic conditions are presented.

  • Energy Community Measures Evaluation via Differential Evolution

    • Abstract: Energy communities are paving the way for new cooperation opportunities related to energy consumption and energy production. Individuals unite in energy communities to reduce the costs related to energy consumption. Although previous work has mainly focused on energy exchange inside the community. This work aims to investigate the Pareto-optimal solutions to the transformation of a historical district into an energy community. For energy efficiency and production measure calculation, a system dynamics model is developed. Multiobjective differential evolution optimization method is employed for the evaluation of energy efficiency and production measures with a focus on net present value, self-sufficiency, annual emission reduction, and specific heat consumption. The optimization target functions can be increased at a cost in net present value. Replacement of household appliances and windows enables significant energy demand reductions while maintaining positive net present value. Electricity production from photovoltaic panels offers an additional pathway to increase selfsufficiency share while maintaining positive net present value.

  • Feeding Management Optimization in Livestock Farms with Anaerobic
           Digestion Plant: A Discrete Stochastic Programming (DSP) Model

    • Abstract: Biogas-based energy production has become a successful strategy for many livestock farms around the world. However, raw materials production is threatened by a growing uncertainty due to effects of climate change on crops cultivation. The aim of this paper is to propose a tool for the optimal design of the biogas mixture, considering respectively the nutritional needs of livestock and the parameters of the biogas process. Within a context of climate variability, a three-stage Discrete Stochastic Programming (DSP) model is applied in a dairy cattle farm with anaerobic digestion plant. This state-contingent approach (DSP model) considers, as uncertain parameters, the watering needs and the yields of forage and energetic crops. The DSP model is compared with equivalent models of expected values to verify the benefits derived from the explicit inclusion of climatic states. The results showed a remarkable improvement in the efficiency of feedstock management, reflecting in a significant reduction in farm costs (11.75 %) compared to the baseline scenario. Whereas, the comparison between the state-contingent approach and the expected value model, showed only slight benefits (0.02 %). This confirms that the DSP model’s ability to offer a better hedged solution increases when high climate variability affects crop yields and irrigation needs.

  • Optimal Energy Scheduling of Appliances in Smart Buildings Based on
           Economic and Technical Indices

    • Abstract: In this article, optimal energy consumption in the smart houses is studied considering techno-economic indices and demand side management (DSM) in electrical grids. The optimal energy consumption is implemented based on optimal scheduling of the household appliances than energy price and capacity of demand flexibility in DSM. The proposed approach is considered as two-stage optimization. Using first stage, energy consumption is modified by optimal shifting of the appliances subject to DSM and energy price. Thus, modified energy consumption is taken into accounted in second stage optimization to maximizing the consumers comfort and minimizing operation cost, simultaneously. The optimization process is done in the MATLAB software, in which objectives in second stage are optimized via lp-metric method. Finally, the performance of the proposed modelling is validated as case studies using numerical simulation.

  • Estimation the Subterranean Sources of Lakes Water Supply Based on
           Bathymetric Survey

    • Abstract: Modern technologies give an opportunity to create a large number of bathymetric maps, but less of them have been focused on processing the water depth data in order to study and estimate the subterranean sources of water object supply. This study aims to create a mechanism for estimating the productivity of subterranean sources of lakes water supply, based on bathymetric survey data. Lake Svitiaz was chosen as the study site as the deepest closed lake of natural origin in Ukraine with an area of 2500 ha and a maximum depth of 58.4 m. To get depth data, ground-based measurements were conducted using an echosounder Lowrance LMS-527cDF. The Lake morphometric changes were investigated, using bathymetric data and Sentinel A, and B data in the digital elevation model (15×15 m). Bathygrahic analysis was performed, allowing selecting areas for further echo-sounding, taking into account complex relief and specific basin forms of the Lake. To develop an appropriate technique for estimating the productivity of subterranean water supply sources, GIS and image (echogram) processing techniques were applied. The research tasks are completed as a technique for detecting ‘tracks’ and a mechanism that is quite effective, particularly for early evaluation of subterranean sources of water supply productivity that can be repeated on any similar water objects.

  • Towards Climate Neutrality via Sustainable Agriculture in Soil Management

    • Abstract: The European Green Deal sets an ambitious target for Europe to reach climate neutrality by 2050. This commitment will be a challenge, particularly in the context of agriculture, as the sector is responsible for sustainable development and food security. However, one of the primary sources of GHG emissions from the agricultural sector is the treatment of soils using nitrogen fertilizers for crops, especially grain crops. This paper aims to assess the GHG mitigation perspective for soil management in the Baltic States and, in particular, to analyse the grain sector in light of sustainable agriculture and towards climate neutrality. To achieve the aim of the study, the analysis was performed in two parts. Firstly, historical and projected GHG emissions of the Baltic States and mitigation measures on agricultural soil management, including cereal growing were analysed as these emissions show a growing tendency. Thus, the study analyses GHG emission trends, including possible mitigation measures for soil management in the Baltic States. The results indicated that for GHG reduction from agricultural soils, some cost-effective measures could be considered for the future, such as the zero-emissions on-farm machinery and equipment, low or no-tillage, or N-inhibitors on pasture. Secondly, as the GHG emissions from cereals increase, potential alternatives to the use of grain production have been explored to assess the highest possible added value from the product use, thus also contributing to GHG reduction. In this regard, according to scientific literature, a survey was created in the form of a questionnaire based on 32 alternatives, 4 large product groups, and 4 criteria for cereal and straw processing. The respondents were requested to provide an assessment of alternatives, and consequently, a multi-criteria decision analysis (MCDA) was performed using the TOPSIS method. The results reveal the best alternatives from each of the product groups consequently is flour from food products, minerals from a pharmaceutical, biogas from a form of transport and reusable tableware from straw-based products, as a possible cost-effective mitigation measure for soil management from the perspective of the development of sustainable agriculture sector and the transition towards climate neutrality

  • PCM Modified Gypsum Hempcrete with Increased Heat Capacity for Nearly Zero
           Energy Buildings

    • Abstract: Low energy building materials based on natural and renewable resources have become popular among customers. The natural occurrence of the raw materials and the idea to move closer to nature with its natural products have brought high interest in hempcrete. Hempcrete is a kind of binder-aggregate material where besides mineral binder, hemp shive aggregate act as a filler. A good technical performance of such composites has been reported before, while the term an ‘advanced material’ for traditional hempcrete lacks some superior properties for civil engineers. This research offers advanced hempcrete-type material where gypsum binder and hemp shives are used as the main components. Additionally, phase change material (PCM) was incorporated into the mixture composition to increase their thermal mass. PCM gives additional thermal heat storage for buildings which makes the building envelope more homogenous regarding thermal stability under outer temperature fluctuations. This could give additional comfort during heating and cooling seasons. Up to 20 wt.% of microencapsulated PCM suspension had been added to the hempcrete mixture composition and heat capacity was calculated and validated with differential scanning calorimetry measurements. Physical and mechanical performance was also evaluated. Results indicate that in the temperature interval from 20 to 30 °C, the heat capacity of hempcrete can be increased to 1901 J/(gK) (by 70.4 %) and it correlates well with theoretical thermal mass calculation. This gives promising results for further development of the material and proves the feasibility of PCM integration in hempcrete.

  • The Effects of Meteorological and Hydrological Conditions on Nutrient
           Losses from Agricultural Areas in Latvia

    • Abstract: Water quality in any stream is affected by complex interactions between natural and anthropogenic factors in a given catchment area. Agriculture has been identified as a major contributor of nitrogen and phosphorus inputs to surface waters in the Baltic Sea region. Although decisions regarding agricultural management practices, e.g. crop rotation, tillage, fertilization, have a direct impact on likelihood and magnitude of nitrogen and phosphorus losses from agricultural areas to surface waters, natural factors such as meteorological and hydrological conditions have a triggering role in processes determining transformations, storage, uptake and losses of nutrients. In order to investigate the effects of meteorological (precipitation and air temperature) and hydrological (runoff) conditions on water quality (losses of total nitrogen (TN) and total phosphorus (TP)) the results of the Agricultural Runoff Monitoring Programme collected at three monitoring sites (Berze, Mellupite, and Vienziemite) during the time period of 1995–2020 were summarized and analysed. The pronounced differences in mean annual air temperature and annual precipitation were observed when the meteorological information representing the periods of twenty years was compared indicating for evidences of climate change. In addition, the relationships between seasonal precipitation and runoff was detected. As affected by the hydrological behaviour the losses of TN and TP in agricultural catchments had large variations depending on the intensity of agricultural production and site location. The changes in seasonal and annual patterns of precipitation, air temperature and runoff may increase the risks of nutrient losses from agricultural catchments in the future.

  • Agro Biopolymer: A Sustainable Future of Agriculture – State of Art

    • Abstract: Due to the rising demand for food and feed, agricultural waste increases, while plastic pollution increases due to hostile human activities. The sustainable way to utilize agricultural waste and promote the bioeconomy concept is to produce an alternative product of plastic, i.e., ‘bioplastic’. This paper used different keywords to perform the bibliometric analysis of the scientific publication related to bioplastic, agricultural waste, and sustainability. Remarkably, results show the increasing research interest in bioplastic with the key developing trends in sustainable bioplastic production, agriculture waste management, biopolymer, and biological processes. The identified developing trends can be used for further research to create a sustainable agricultural sector and produce higher added-value products. Moreover, this study discovered that the agro-biopolymer area needs more focus on sustainable development considering the economic, social, and environmental dimensions.

  • Mitigating Overvoltage in Power Grids with Photovoltaic Systems by Energy

    • Abstract: The rise of photovoltaic (PV) penetration is contributing to the increasing incidence of overvoltage detection in the electrical grid during times of high-power generation. Overvoltage can cause disturbances or (partial) failures in the electrical supply network, since the components used are designed for a certain voltage band. One option to counteract too high voltage levels and thus ensure power quality, grid stability and resilience is the absorption of active power by means of a battery energy storage system (BESS). In this paper, we first built a suitable simulation setup for a typical European network section, including a large-scale PV system connected to the 10 kV level and a BESS model. A suitable charging and discharging algorithm for the BESS with the aim to realize peak shaving for the grid voltage was developed and implemented. Simulations, performed in MATLAB/Simulink®, show the dependence of the battery capacity and power on the grid-serving effect of BESS. By determining appropriate values for these two factors a significant reduction of the voltage level could be achieved.

  • Environmental Assessment of the Fresh Sausage Transformation Process in
           the Italian Context: An LCA Study

    • Abstract: The problem of Climate Change and the related issues of greenhouse emissions, and energy consumption are among the most debated topics nowadays at international level. It is essential to find viable solutions also in the agri-food sector, moving towards production processes that were more sustainable, energy saver, and possibly follow a circular economy approach. The Circular Economy is not fully a brand-new concept, as it is based on a combination of fundamental and founding concepts such as Industrial Ecology, Regenerative Design, Natural Capitalism, Cradle to Cradle approach and Blue Economy. However, the novelty is in the attention that this concept is gaining among business practitioners, consultancy firms, governments, NGOs and associations, and academics. The aim of this study is to perform a Life Cycle Assessment related to one of the main products of a company of the agri-food sector in central Italy. The product analysed was fresh sausage and the functional unit considered was 100 kg of fresh sausage. The analysis was performed in order to identify the environmental impacts caused by the different transformation processes along the product life cycle, to highlight the critical phases and to plan improvements in terms of efficiency of the production process, with consequent improvement of the environmental performance. Particular attention was paid to the transport and to the energy consumption phases.

  • Life Cycle Sustainability Evaluation of Potential Bioenergy Development
           for Landfills in Colombia

    • Abstract: The Colombian energy matrix faces significant changes toward meeting its energy needs while fulfilling its pledges in the Intended National Determined Contributions linked to the Paris Agreement. The country has developed a plan for energy transition with a 2050 horizon, a strategy reflected and supported by new legislative packages. Within its design, biomass and biomass waste play a vital role in bioenergy production; however, the benefits of deploying new bioenergy production facilities have not been fully accounted for, including only an economic and climate change perspective. In this work, a Life Cycle Sustainability Assessment of a potential bioenergy plant for industrial symbiosis with the largest landfill in the country is undertaken, avoiding environmental burden shifting between environmental damage categories and exposing the social potential of such projects. The results show how these types of projects are economically feasible and have the potential to boost the sustainable development of local communities, which under the Colombian context, have been structurally relegated from conventional economic growth for decades.

  • Economic Performance of a Hybrid Renewable Energy System with Optimal
           Design of Resources

    • Abstract: The renewable energy is expanding in the sub-systems of distribution electrical grids, due to having low energy costs and high reliability. In this study, off-grid design of the hybrid energy system based-renewable resources is proposed for a house in Hamadan city in Iran. The resources are designed based on economic and climate data such as battery, solar cells, wind turbines, and electrolyser/fuel cell. The design of mentioned resources is done with attention to twofold optimization modelling including operation cost (OC) and net present cost (NPC). The modelling of resources is implemented in HOMER software based on optimal sizing and installation costs. In the numerical simulation, the three optimal designs are presented to meet electrical demand with minimum costs and high reliability.

  • The ICCEE Toolbox. A Holistic Instrument Supporting Energy Efficiency of
           Cold Food and Beverage Supply Chains

    • Abstract: Cold supply chains of food and beverage sectors represent one of the main drivers of the EU total final energy consumption. Within this context, food quality losses, changes in temperature regimes, energy use, environmental burdens, and the economic viability of energy efficiency measures are essential aspects to consider for improving cold supply chains’ overall sustainability. This paper presents a dedicated toolbox, developed within the Horizon 2020 project ICCEE, for supporting decision-making and actors to assess energy efficiency path within a specific type of food cold-supply (i.e., meat, fish, milk and cheese products, fruits, and vegetables). More in specific the toolbox offers support for decision-makers to understand and minimize the specific energy consumption, to decrease the overall environmental impact even including non-energy benefit evaluation many times underestimated. The six separated tools merged within a unique toolbox consider different methodological approaches such as: assessment of the whole energy requirements in stock and flows considering the storage impact, the logistics and quality losses over time, implementation of Life Cycle Assessment and Life Cycle costs within the environmental and financial assessment of energy efficiency measures, based on a benchmarking approach. Finally, a specific approach implementing Multi Criteria Analysis was developed on selected key performance indicators such as specific and cumulated energy consumptions, quality losses and environmental burdens (i.e., global warming potential and water scarcity). The latest version of the ICCEE toolbox is available as free downloadable package on the ICCEE website.

  • Potential of Using WVO for a Restaurant EV Charging Station

    • Abstract: This research comprised an evaluation study for a charging station based on waste vegetable oil or biodiesel fuel. The biodiesel was produced from waste vegetable oil (WVO) and will be used (or the WVO) to charge electric cars for restaurant’s customers in their car park. The main concept behind the charging station is to be part of a restaurant that serves its customers and then uses its WVO or biodiesel to fuel a diesel engine that generates electricity to charge their electric vehicles (EV). The economic and environmental impacts of the direct use of WVO-EV charging station are promising because the costs associated with purchasing WVO are lower than those of purchasing crude oil or gas. There are several options and scenarios when selecting the perfect sized generator; using charging up to a maximum rated power of 6.6 kW is more feasible despite its higher initial cost as the simple payback period will be less than 3 years and the internal rate of return of the project is 44 %. The total saving at the end of the project for a generator with maximum rated power of 10 kW (option B) is $ 58 000. Conversely, for a generator with maximum rated power of 6.6 kW (option A) the project will cover its initial cost in around 4 years and the internal rate of return is 26 %. The total saving at the end of the project is $ 52 000. Furthermore, lower amount of greenhouse gases is produced from the burning of WVO directly. The final results showed that WVO is more feasible as it is available for free and could be burnt directly in the diesel engine. In economic terms, the project is feasible for both WVO and biodiesel as it has a high net present value and short payback period. A WVO-EV charging station can also improve the national economy by preparing it for the electric car era and, if applied to a large number of restaurants, will save a significant amount of electricity and reduce the expected strain on the electricity grid caused by the increasing number of electric cars.

  • Removal of Cd, Cu, Ni, and Pb from Nanoscale Zero-Valent Iron Amended Soil
           Using 0.1 M Acetic Acid Solution

    • Abstract: The purpose of the study was to evaluate the possibility of removing heavy metal cations from single-metal spiked soil samples, which were pretreated with nanoscale zero-valent iron (nZVI) particles. Sandy soil was artificially contaminated with copper (Cu), cadmium (Cd), nickel (Ni), and lead (Pb). Contaminated soil samples were amended with different doses of nZVI (0.35, 0.70 and 1.05 %). A sequential extraction method was used to determine the fractionation of heavy metal cations in the control and nZVI amended soil samples. A solution of 0.1 M acetic acid (pH 3.0) was used to investigate the removal of heavy metals from control and nZVI-amended soil samples. The results showed that nZVI reduced the amount of metals in the exchangeable form and increased the proportion of these metals associated with amorphous iron (Fe) oxides. The results also showed that the removal efficiencies of heavy metals increased with increasing nZVI dose, that is, from 46.9 %, 5.77 %, 33.5 %, and 2.70 % to 55.9 %, 12.3 %, 46.2 %, and 3.79 % for Cd, Cu, Ni, and Pb, respectively. The study indicated that the application of nZVI in soil could be beneficial for subsequent removal of heavy metals from soil using 0.1 M acetic acid solution.

  • Hydrothermal Carbonisation of Biomass Wastes as a Tool for Carbon Capture

    • Abstract: Replacing fossil resources with bioresources is one of the promising directions for more environmentally friendly energy production, but the production and processing of biomass generates a large amount of waste with limited use and recycling possibilities. In this respect Hydrothermal Carbonisation (HTC) offers a sustainable and cost-effective solution for disposal and creation of new products from biomass through resource recovery and through climate-neutral process. In this study the impact of biomass type and HTC conditions on the yield and properties of artificial humic substances and hydrochar to achieve carbon capture aim has investigated. A major impact on the yield of HTC products do have the duration and temperature of the treatment, as well as catalyst used (pH of the reaction) and changing the carbonisation conditions it is possible to design the desirable composition of obtained products. During HTC process significant changes of the biomass composition happens resulting in the removal of most labile components. Although the carbon dioxide sorption capacity of hydrochar is relatively low, after activation efficient sorbent (activated carbon) can be obtained, prospective for carbon capture aims.

  • Decreasing the Load of Air to Water Heat Pump Systems on Electrical Grids

    • Abstract: This article focuses on decreasing the energy taken from the electrical grid by air to water heat pumps in buildings that use renewable energy. Conventionally the majority of the produced renewable energy is not used directly to operate the heat pump. An energy management concept was developed, with a main new parameter – RCOP that enables to create an optimal working schedule that considers the renewable energy availability and heat pump coefficient of performance in relation to the weather. The concept was proven with computer models that use weather forecasts, renewable energy production, and heat demand. The achieved yearly savings in grid-electricity used by the heat pump were 14.3 %. The fluctuations in the grid load were decreased which as well were quantified by a lower standard deviation of the demand. In months with the best renewable energy availability, the grid electricity savings can reach up to 70 %.

  • Comparison of Changes in Electricity Consumption Distribution in Day and
           Night Scale Caused by Nord Pool Spot Prices Volatility

    • Abstract: Under free market conditions, there should be a correlation between price and demand. In the electricity market, it is not possible to shift all consumption to hours that are more favourable. Therefore, free market rules do not fully apply to the electricity exchange market. Household consumers have a better ability to shift their energy consumption. At the same time, a large number of household consumers have fixed-price contracts and are therefore not affected by the sharp price changes, so it can be said that they do not actively participate in the stock market. They do not need to shift their electricity consumption. High-consumption industrial companies have very low possibilities at all to react to the stock market changes. The aim of this study is to find out how much electricity consumption has been able to shift in a situation where electricity prices in Estonian were extremely high and volatile. Electricity prices are usually lower at night-time, so it can be assumed that consumption will be shifted to night-time if possible. Examining the change in the distribution of night- and daytime electrical consumption over the years, it is possible to analyse the effect of energy prices on consumer behaviour during periods of high volatility.
