HYDROGEN PRODUCTION
Hydrogen production by electrolysis (green hydrogen)
The water electrolysis of (electro-chemical vízbontás) emissions without, we can produce clean H2 gas and O2 as a by-product formation beside. The vízbontás occurring upon oxidation (anódos reaction) and reduction (cathode reaction) space separated set off, thus avoiding the explosive product mixture formation. The electrode in an electrolyte solution and a solid separator, or a these two at the same time replace solid electrolyte separates, which ensures the electro-chemical processes necessary for proper ionvezetést.
The alkaline vízelektrolízis the most mature technology, which over the past 100 years have been an industrial scale is also used for H2 production. During this process, an alkaline electrolyte solution (typically KOH solution) electrified, they the cathode and anode between. The two cellat gets to separate, so the O2 and H2 mix of prevent, a porous diaphragm is used. The electrodes between solution layer caused by the electrical resistance (and this, together with the cell voltage) in order to reduce has been developed for proton exchange-membrane (PEM) separated electrified cells. In these the anode and the cathode of a membrane directly through each other is pressed (the fuel cells to a similar solution). The anode side of clean water oxidation takes place, while the katódon with the same speed in the membrane átvándorló H+ ions reduction of hydrogen.
Other novel hydrogen production methods.
A number of other, less mature green hydrogen production technology is also available or under development. For example, the direct vízbontás using solar energy (e.g., thermal, photo- or combine photo-thermal catalysis method).
The biological hydrogen production (e.g., algae or bacteria), the hydrogen rapporteur contained too, further CCU products (e.g., methane, alcohol) production allows. The explorer research in addition to, national applied research capacity available on the subject of the SZTE-n, PE-n, the BME-n as well as the Power-to-Gas Hungary Kft. bond within.
The hydrogen fuel cells, gas turbine in and internal combustion engines can be energy-production use. Gas turbine in currently, it's only natural gas mix by applying the high égőkamrai temperature due. The production of energy and transport use from the perspective of the main converter, the fuel cells are, therefore, referred to as these are addressed in more detail.
The power system balancing
The wind and solar energy by the energy produced significantly fluctuate, in addition, the szélpark often they are far away from consumers. Therefore, this performance or cable shall be transmitted to the consumer centres, or store, you will need to feed the energy system. The hydrogen technology is one way to do this. Here's the electricity produced from renewable sources in an electrolysis the process of nutrition is used, in which the water is electrochemically hydrogen and oxygen share – a form in which it is the energy storage is possible and transport it to become visible. In this way produced hydrogen then switch back to active electrical energy. This green hydrogen in the security of supply and the network's resilience to increase serve.
The hydrogen storage and the use of methods of
The thus produced hydrogen can be used directly. For example, fuel cells using electrical energy can be converted into, or as a raw material for use in the chemical industry. The first question here is, how to this hydrogen is made available for such purposes.
