Producing hydrogen is an essential first step in the realization of any activity involving hydrogen as an energy carrier. Thereby, we distinguish different characteristics of the process.
Key metrics #
Greenhouse gas emissions: Processes used for the production of hydrogen can be more or less greenhouse gas intensive. The most common production method used today is steam reforming. It emits 6.6 to 9.3 tonnes of carbon dioxide per ton of hydrogen. On the other hand, the production of hydrogen with water electrolysis (so-called green hydrogen) can be 100% emission-free.
Use of non-renewable resources: A second important feature characterizing the production processes is whether non-renewable resources are required. For example, fossil fuels are needed for hydrogen production using steam reforming. So-called blue hydrogen is created with steam reforming does not emit carbon dioxide, however, it is still produced with non-renewable natural gas.
Location in the energy infrastructure: The fact that hydrogen is a light gas and cannot be easily transported implies that the place of production plays a crucial role. Consequently, it is conceivable that hydrogen could be produced on a large scale in deserts. However, there are also advantages resulting from the production of hydrogen at decentralized locations in the power grid. Specifically, these are locations where the surplus of electricity becomes increasingly large.
Producing hydrogen with GRZ #
GRZ Technologies has erected hydrogen production plants based on different types of electrolysis technology. The size of the sites ranges from lab to MW-scale, our teams have installed PEM, alkaline, and AEM electrolysis technologies for our clients.
Producing hydrogen in sufficient amounts is a key prerequisite for a successful energy transition. Therefore, especially in the transition’s first phase, all environmentally friendly production methods should be embraced. Furthermore, it is helpful if they can benefit from favorable regulatory conditions. Sufficient availability of hydrogen for various applications is crucial.
The produced hydrogen can be used in downstream processes. GRZ Technologies’ products are often the first component placed downstream of the hydrogen production process. They help to generate economic value from the resource.
