Hydrogen dreams burst: Picea system does not make houses self-sufficient!
Österreich - The hydrogen system "Picea" from the HPS company was originally supposed to make single -family houses 100 % energy self -sufficient. However, the project now faces serious challenges because it is insolvent. According to ÖA> the idea of creating a fully energy self-sufficient home is technically unrealistic. Fuel cell stacks require regular maintenance that is associated with high costs.
The economic framework for the Picea system is also difficult. The total costs for acquisition, operation and maintenance do not pay for themselves, and high insulation standards consider the target group considerably. With a cost of around € 70,000 plus annual maintenance costs of € 1,000 for essentially low savings, the advantages are in no relation to the expenses. Average families could therefore live more sensibly almost energy self -sufficient instead of striving for the last 10 % to 20 % of energy praise.
technical challenges and solutions
The system of HPS integrates battery, electrolyser and fuel cell and enables predictive energy management. As reports Faboro , it is a sustainable and electrically self -serving house current system. In addition, the waste heat resulting during the operation of Picea is either used as heating or for hot water, which can lead to a reduction in heating costs.
The system is designed in such a way that it can be easily installed and serviced and its users receive information about environmental protection and optimal demand control via software. Despite these positive aspects, it is clear that reality remains challenging for many families.
criticism and media perception
Media reporting on the Picea system was according to Econews often unreflected and inaccurate. Interested readers are encouraged to inform themselves independently about Picea on the Internet to get a complete picture of the situation.
In parallel to the challenges of hydrogen technologies, the discussion about sustainable resource use is of great importance. The Fraunhofer-Gesellschaft emphasizes that there is a need to pass from linear to circular exploitation systems. This is important to protect resources and promote sustainability. The circular economy based on the principle of minimizing resource consumption and waste production could also potentially be of great importance for the technologies around hydrogen benefit and storage.Overall, the situation around the Picea system shows that there are still considerable economic and technical challenges during the technological advances in the area of hydrogen, which must be considered in order to advance the sustainable use of energy. The transition to a circular system could offer long -term solutions.
