# A Review of Worldwide Strategies for Promoting High-Temperature Heat Pumps
## 4 The Promotion of IHPs over the World
### Australia  
In Australia, efforts to promote the adoption of HTTHPs in industrial settings are gaining traction as part of the broader push towards decarbonization and energy efficiency. The Climate Change Authority has identified HP importation as a key indicator of decarbonization progress in the built environment [69]. Given that Australian industry accounts for a significant portion of the nation's energy consumption, with 52% of it attributed to process heat, valued at approximately AUD 8 billion annually, there is a pressing need to transition towards more efficient technologies

Currently, the predominant sources of heat in Australia are gas combustion followed by coal. To meet decarbonization targets and increase energy productivity cost-effectively, Australian businesses are encouraged to adopt technologies that can efficiently provide industrial heat while integrating renewable energy generation. Notably, there are already available, proven IHIPs and thermal battery technologies that offer reliable energy supply and flexibility to maximize the benefits of renewable energy and demand response strategies. Australia has taken concrete steps to facilitate the adoption of HP technology. For instance, the launch of the Heat Pump Estimator, an online estimation tool, assists businesses in appropriately sizing HPs to replace gas boilers, thus reducing energy costs and advancing decarbonization efforts to achieve net-zero targets [65; 70]. In New South Wales (NSW), the Net Zero Manufacturing Initiative is a significant effort aimed at providing up to AUD 275 million in funding across three programs: the Clean Technology Innovation, the Low Carbon Product Manufacturing, and the Renewable Manufacturing programs. These initiatives aim to accelerate R&D and commercialization of emerging clean technologies and expand local manufacturing capacity for low-carbon products and materials. By supporting the development of innovative technologies such as HTHPs to a market-ready level, this initiative contributes to increasing industrial efficiency, decarbonization, and the adoption of renewable energy in the industrial sector [71]. The government is actively investing in initiatives to reduce emissions and enhance the resilience of high-emitting industries, allocating AUD 305 million in grant funding for this purpose. This funding supports key objectives outlined in the High Emitting Industries (HEI) initiative, which aims to decarbonize high-emission facilities, accelerate transformation projects, and foster prosperity in a zero-emissions economy [72]. HEI is a focal point of the Net Zero Industry and Innovation Program (NZIIP), a flagship program designed to help NSW achieve a 50% reduction in emissions (compared to 2005 levels) by 2030 and reach net zero emissions by 2050. This program is a cornerstone of the Net Zero Plan Stage 1: 2020-2030, aiming to provide over AUD 1 billion to support and collaborate with industries in reducing emissions and thriving in a low-carbon environment [73]. Under the Net Zero Industry and Innovation Investment Plan 2022-2024, various funding opportunities are available for industry. These include the following:  
* AUD 305 million allocated for abatement projects at high-emitting manufacturing and mining facilities;
* AUD 55 million earmarked for the establishment of clean manufacturing precincts in the Hunter and Illawarra regions, along with support for their infrastructure and supply chains;
* An additional AUD 300 million dedicated to new low-carbon industry foundations. Australia has implemented a comprehensive suite of programs and initiatives to reduce emissions across businesses, industries, and among consumers.
