Method of the best available technology and low carbon future of a combined heat and power plant
Dušan Strušnik, Marko Agrež, 2022, original scientific article

Abstract: The low-carbon development strategy and ecological awareness of a combined heat and power (CHP) plant is the key factor that enables further development of such systems. CHP plants are subject to rigid European ecological guidelines, which dictate the pace of development of global thermal power engineering. For this purpose, the European Union issued a special Directive for the promotion of heat and power cogeneration, and is established with the best available technology (BAT) method. Even though the production of electricity using carbon-free technologies is on the rise, the production of electricity by fossil fuel combustion cannot be avoided completely. The meaning of the operation of the CHP plant is reflected particularly in the provision of tertiary services to the electric power system, regulation of the network frequency, particularly in winter months, when electricity production using carbon-free technologies is limited. In CHP systems, the low-carbon future is linked intricately to high investment costs and these impacts the final price of energy. Using the BAT method, the article presents the advantages of energy production in a combined heat and power plant, an example of the restructuring of a larger CHP system into a low-carbon plant and guidelines for further development.

Design of wFoil 18 Albatross with hydrogen technologies
Nejc Zore, Jurij Avsec, Urška Novosel, 2023, professional article

Abstract: This article discusses the design of fuel cell propulsion for 18 albatross foil vessels. The purpose of this article determined the economic viability of such propulsion. WFoil 18 Albatross was chosen for a high-speed, low-power propulsion system. The hydrogen propulsion system for the Albatross vessel consists of the following parts: - Electric motor (Emrax 188) to convert electricity into mechanical energy; - Battery (LG RESU 3.2EX | LG Battery System), which provides electricity in case of emergency or adds the necessary energy to run the engine at maximum power; - Controller (EmDrive 500), which provides enough energy to pass between the elements of the propulsion system; - Fuel cell (Hydrogenics HYPM-HD 30 POWER MODULE), which is the primary source of energy; - The tank (tank for hydrogen gas type 3) stores fuel, which in our case is hydrogen. The brackets indicate the parts that have been selected for the hydrogen propulsion system. The approximate weight of all these parts is about 249.1 kg and the price of all these parts is about 55254 €. All prices are from 2020 and are subject to change. The main idea in the construction of this charging station is the use of seawater and solar energy or renewable energy sources for hydrogen production. The components of the charging station are Solar cells (LG NeON 2), Desalination (CRYSTAL EX PURE), Electrolysis (Nel C Series C10), and Charging station (Haskel (Version with air compressor)). The brackets indicate the parts that have been selected for the charging station. The approximate weight of all these parts is about 10236 kg and the price of all these parts is about 517664 €. All prices are from 2020 and are subject to change.
