What is the most cost-efficient heat source in industrial processes?
5 answers
The most cost-efficient heat source in industrial processes can vary depending on factors such as technology, energy prices, and efficiency. Research comparing different heat supply processes highlights that high-temperature heat pumps (HTHP) can offer significant cost advantages. These HTHP systems, when operating with a coefficient of performance (COP) of four and under specific energy price conditions, have been shown to be the most economical option for heat production. Additionally, the study emphasizes that the economic feasibility of solar process heat technologies, such as solar thermal (ST) and photovoltaic (PV) systems, is influenced by factors like solar resource availability and investment costs. While ST energy has traditionally been favored due to its efficiency, the evolving costs and efficiencies suggest that PV solar energy could become a competitive alternative in certain scenarios.
How does a "data space" prevent privacy risk?
4 answers
A "data space" prevents privacy risks by enabling data sovereignty, control enforcement, and addressing users' concerns about data ownership. The International Data Spaces (IDS) standard ensures data sovereignty by allowing data providers to maintain control over their data even when shared with others. Additionally, the IDS facilitates the enforcement of usage control policies, verifying that data processing devices uphold these policies. Users' primary concern regarding privacy risks with connected objects is data ownership, emphasizing the need for tools that bridge the gap between users' mental models and the functionalities of connected objects. By incorporating privacy analysis approaches and tools like the Connected Peekaboo Toolkit (CPT), data spaces can better design data-enabled objects with enhanced privacy awareness.
