Industrial high temperature heat pump (IHTHP) offers an efficient solution for industrial thermal demands which account for a large proportion of total energy consumption. Since it is in early deployment, optimizing its utilization and improving its economic and environmental attractiveness are essential. To address these issues, pinch analysis, techno-economic analysis, environmental impact assessment, and sensitivity analysis are conducted. Results indicate that switching IHTHP from single heating to combined cooling and heating operating mode could improve the system's efficiency by 21.3 %, achieving considerable electricity savings at regional or national scale. Moderate carbon tax (CT) proves most effective in establishing the economic advantage of IHTHP with minimal additional improvements. Prioritizing promoting IHTHP in specific regions offers immediate economic benefit, due to existing favorable conditions about industrial resources, electricity price, and electricity CO2 emission in these areas. Reducing electricity emission or increasing unit efficiency would position IHTHP as the most environmentally-friendly choice. Without relying on national electricity emission reduction, establishing localized hybrid PV-grid system in industrial park with adequate PV share (RPV) provides a short-term realizable environmental advantage for IHTHP. Higher RPV, moderate CT, and subsidies may be required to ensure the economic competitiveness of this scheme. Finally, sensitivity analysis reveals that IHTHP's efficiency is most crucial for its economic advantage while the electricity cleanliness primarily determines its environmental benefit. This work proposes practical and short-term achievable strategies to enhance the competitiveness of IHTHP for broader application, supporting the sustainable transition of industry.
