Kádár Péter presented the „Smart Energy projects at Óbuda University”.
The first presenter was Pál Kiss from Thermowatt Ltd., who presented their company and thermowatt technologies. THERMOWATT LTD. has been using a patented innovation to generate power from wastewater heat. He presented their solutions that make building operations cheaper in terms of energy costs, for heating and cooling buildings. The system is based on a heat pump, equipment now commonly used for supplying heat energy to buildings. Their services include custom engineering, financial planning, and operation control. Pál Kiss presented also the technical background of thermowatt technologies.
Ottó Hujbert from Zalavíz Plc. presented the SCWG-HU technology.
He presented the integration of SCWG technology that built into wastewater plants can bring us closer to the realization of a circular economy. SCWG processing of sewage sludge greatly reduces the quantity of solids to be transported and deposited.
The integration of the SCWG-HU technology into municipal and industrial wastewater plants, in addition to a significant reduction in carbon dioxide emissions, can double their energy production and make them energetically self-sufficient.
The benefit of Zalavíz Zrt's sample project is that it enables the determination of the processing parameters of other wet biomasses using the SCWG-HU technology, as well as the optimization of equipment sizes and reaction parameters required for their SCWG processing. Their SCWO and SCWG technology have a pending patent, and SCW boiler has a granted patent. SCWG can release about 70% of digested sewage energy, depending on capacity, as synthesis gas; SCWG-HU can practically double the energy production of the wastewater plant; Depending on the catalyst, syngas with a hydrogen content between 20-50% is suitable for significantly reducing the specific carbon dioxide emissions of the wastewater plant.
The following presenter was Antal Csordás, senior development enginer at Kontakt-Elektro Ltd. introduced the “Fuel cell technologies at Kontakt-Elektro Ltd.”
Kontakt-Elektro started dealing with fuel cells 15 years ago. This first development result of the company in this field was the production of a 100W fuel cell stack. The next step was to develop the first stack further and change as many of its components to own developed ones as possible. Their first equipment was a 15kW power supply that rolled on wheels, which was perfectly capable of providing energy for concerts, festivals, and movie productions due to its noise strain and zero emission (FCPS-15 – introduction). They used the module of Hydrogenics for a little ship designed for recreational purposes which uses a 15kW electric engine and an accumulator-fuel cell hybrid power supply system, where the hydrogen supply is rechargeable using a 300bar composite cylinder storage system. their plan for the future is to develop a bigger ship based on the 15kW small ship.
After that Tamás Várhely from GET Ltd. presented their lighting technology solutions and their energy-saving system in the lighting and construction sector. He also presented their new technology development in the lighting sector that is related to sports, new LED light sources, and the state-of-the-art computerized control options that can be utilized for the enhancement of sports performance. The prototype includes individually controlled LED lights and a UV-C fluorescent tube. Said developments result in a complex sports lighting system. This integrated and innovative product simultaneously responds to the current pandemic-related challenges and makes use of the latest lighting technology and control features while providing an optimal environment for even the indoor activities of athletes.
Representatives of the Hungarian Hydrogen Technology Association Butsi Zoltán and Dr. András Tompos gave a presentation.
First, Butsi Zoltán introduced their activity and their aims. The Hungarian Hydrogen Technology Association maps engage and encourage cooperation among domestic players active in the field of hydrogen technologies, as well as prepares studies and provides strategic proposals for domestic policy – primarily for energy and transport policy, climate protection, and industrial development. Hungarian Hydrogen Technology Association is part of a Collaboration and cooperation project, in a consortium of 11 research sites in Hungary headed by University Pécs.
Tha association has two main areas:
At the end of the day, János Szilasi presented the Toyota Sakura Ltd., especially the Beyond Zero Strategy on the Hydrogen sector. First, he talked about the history of Toyota, then moved on to the new technology. The main aim of Toyota Beyond Zero is decarbonization by high-voltage batteries, hybrid systems, fuel cells, and ice hydrogen. He showed a lot of different vehicles that depend on hydrogen technology and talked about their specifications. At the end of his presentation, he mentioned that Toyota Hungary plans to implement a Hydrogen innovation center in Hungary, which would be an education Research and development center.
