H-TEC Systems has presented its new PEM electrolysis Hydrogen Cube System (HCS), for the production of green hydrogen.
The modular system is suitable for large multi-MW PEM electrolysis plants and applications in the industrial, chemical, and renewable energy sectors. The modular system allows for successive expansion and scaling, as projects are often already designed for later expansion.
Green hydrogen production on a multi-megawatt scale
The HCS is a modular building block system to realize large PEM electrolysis plants for producing green hydrogen. For this purpose, 2 MW Cubes can be combined to form multi-megawatt plants. The cubes achieve a system efficiency of 74 percent and are equipped with an integrated process water treatment and power supply. In addition, fresh water and hydrogen treatment or heat extraction can be added to the system, depending on the customers’ requirements. A 10 MW HCS from H-TEC Systems can produce 4,500 kg of hydrogen per day. With 10 MW of renewable energy, 40 to 50 trucks or busses could be refueled with green hydrogen every day. The system is designed for modular expansion. All modules can be linked so that the entire plant can be centrally controlled and monitored. The concept is suitable for plants that are to be expanded over the next few years. Projects can thus also start with a 4 MW system, even if the long-term goal is 50 MW or more. For further information see the IDTechEx report on The Hydrogen Economy, Fuel Cells, and Hydrogen Production Methods.
Extended application areas enable high CO2 savings
With this innovative system, H-TEC Systems is expanding into larger industrial applications and thus enabling extensive CO2 savings through the use of green hydrogen, as compared to fossil resources. The HCS is suitable for applications in industrial production, such as chemical plants or steel production, as well as in the field of mobility (fleet refueling). For wind farms or PV park operators, the conversion of renewable energy into green hydrogen is a very viable option. Steel production, which is one of the largest producers of emissions in Germany, provides an example of possible CO2 savings. According to the German Steel Industry Association(i), 26 tons of CO2 emissions can be saved for every ton of climate-neutral hydrogen used in steel production. A 10 MW HCS from H-TEC Systems with a daily production of 4,500 kg of green hydrogen would therefore reduce CO2 emissions by 117 tonnes per day, or 42 thousand tonnes annually.
