RAPESEED PELLET - A BYPRODUCT OF BIODIESEL PRODUCTION - AS AN EXCELLENT RENEWABLE ENERGY SOURCE
PublikacjaVegetable oils are renewable feedstock currently being used for production of biofuels from sustainable biomass resources. The existing technology for producing diesel fuel from plant oils, such as rapeseed, soybean, canola and palm oil are largely centered on transesterification of oils with methanol to produce fatty acid methyl esters (FAME) or biodiesel. Rapeseed pellet - crushed seed residue from oil extraction is a byproduct...

Smart heating system for home extending utilization of renewable energy sources
PublikacjaIn the paper a modern approach to smart home heating is presented. Proposed solution utilizes at least two low-polluting energy source technologies. The main idea is to connect well known ecological energy sources in a way that they can support each other and minimize risks of failure when using single system or even both of them but managed in separate way. Considered energy technologies, used separatelly, have disadvan-tages,...

Achieving energy neutrality in wastewater treatment plants through energy savings and enhancing renewable energy production
PublikacjaWastewater treatment plants (WWTPs) consume high amounts of energy which is mostly purchased from the grid. During the past years, many ongoing measures have taken place to analyze the possible solutions for both reducing the energy consumption and increasing the renewable energy production in the plants. This review contains all possible aspects which may assist to move towards energy neutrality in WWTPs. The sources of energy...

Comparison of Renewable Energy Sources in ‘New’ EU Member States in the Context of National Energy Transformations
PublikacjaThe European Union strives to create sustainable, low-carbon economies; therefore, energy policies of all member states should move towards renewable energy sources (RES). That concerns also the so-called new EU member states. These countries, on the one hand, are characterized by significant historical similarities in terms of post-communist legacy and adopted development strategies linked with the EU membership, and on the other...

Techno-economic assessment of cooperation of hybrid renewable energy sources with hydrogen storage
PublikacjaThe paper presents a technical and economic analysis of the power supply for a model industrial facility with the use of the most promising renewable energy sources (RES), supported by a hydrogen energy storage. This scenario was compared with the variants of supplying the facility directly from the grid and from RES without energy storage. A strategy was proposed for powering the plant aimed at maximising self-consumption of self-generated...

Hybrid Multi-Criteria Method of Analyzing the Location of Distributed Renewable Energy Sources
PublikacjaThis paper presents the development and the application of a hybrid multi-criteria method, the combination of the Analytic Hierarchy Process (AHP), and numerical taxonomy (NT),to support the decision making on the location of distributed renewable energy sources meetingvarious types of assessment criteria. Finding criteria weights, using the AHP method, eliminates thedisadvantage of NT—which, in current form, is defined by its...

Application of renewable energy sources to drive organic Rankine cycle micro CHP
PublikacjaOdnawialne źródła energii rzadko znajdują zastosowanie przy stawianych obecnie wymaganiach przez nowoczesne ciepłownie. Pojawiła się unikalna okazja pomocy przy wprowadzeniu na rynek elektrowni zoptymalizowanej dla tych nieużywanych i pomijanych źródeł ciepła. Organiczny obieg Rankine'a jest podobny do konwencjonalnych turbin parowych, wyjątkiem jest płyn napędzający turbinę, którym jest płyn roboczy o dużej masie cząsteczkowej....

Renewable Energy in the Pomerania Voivodeship—Institutional, Economic, Environmental and Physical Aspects in Light of EU Energy Transformation
PublikacjaIn the era of globalization and rapid economic growth, affecting most world economies, increased production and consumption are leading to higher levels of energy production and consumption. The growing demand for energy means that energy resources from conventional sources are not sufficient; moreover, its production generates high costs and contributes to the emission of greenhouse gases and waste. In view of the above, many...

Biomass as a reliable renewable energy source in the fulfilling the white paper poland-eu requirements
PublikacjaZgodnie z wytycznymi z Białej Księgi Unii Europejskiej, wzrost wykorzystania odnawialnych źródeł energii powinien osiągnąć 7,5% w 2010 r. i 14% w 2020 r. o ogólnym zużyciu energii w Polsce. Analizę sytuacji energetycznej Polska w przeszłości i przewidywania zmian globalnych i regionalnych w odniesieniu do produkcji i zużycia energii, prowadzą do wniosku, że biomasa może być możliwym źródłem energii odnawialnej dla realizacji tych...

Optimisation of cooperation of hybrid renewable energy sources with hydrogen energy storage toward the lowest net present cost
PublikacjaThe paper presents the results of a technical and economic analysis of the power supply for a model industrial facility based on intermittent renewable energy sources in the form of wind turbines and photovoltaic modules, supplemented with hydrogen energy storage. The adopted power supply strategy assumed the maximisation of self-consumption of self-produced electricity. Six variants were considered, including two with an energy...

The Application of a Multi-Criteria Decision-Making for Indication of Directions of the Development of Renewable Energy Sources in the Context of Energy Policy
PublikacjaThis paper presents the application of multi-criteria decision-making (MCDM) for evaluating what technologies using renewable energy sources (RES) for electricity production have the chance to develop in Poland under the current socio-economic conditions. First, the Analytical Hierarchy Process (AHP) method was used to determine the weights of the optimization criteria. Five main criteria and 30 sub-criteria were identified. Next,...
