“…Currently (as of 1 May), there are five relevant articles published in 2023, so we predict that there will still be a high level of research interest this year. The main reason for this is that with the advancement of zero carbon plans around the world, there is now more and more research into HENG fuels and many countries have started HENG fuel projects. − …”

Cooking is a daily activity in every household, which consumes energy and produces pollution. Using clean gas fuels instead of traditional solid fuels will significantly reduce household air pollution. Although the use of clean-burning burners can reduce emissions, early domestic gas cookers had poor thermal performance. Currently, even small improvements in efficiency can result in significant energy savings due to the large number of domestic gas stoves in use. There has been a long history of research into the development of domestic gas stoves to improve performance and reduce energy consumption. Meanwhile, research into the use of hydrogen-enriched natural gas as a promising environmentally friendly fuel is increasing. In this paper, we perform a descriptive statistics and graphical visualization of network analysis by combining common databases with Bibliometrix. We also analyze the energy balance of domestic gas stoves and the influence of a single factor and multiple factors on stove performance. Then we provide a detailed overview of some research technologies in enhancing the thermal performance of gas stoves. We also discuss the research progress and application prospects for the use of hydrogen-enriched natural gas as a fuel in domestic gas stoves and identify areas for future research and issues that need attention.

“…Hydrogen storage and transport also pose notable challenges, necessitating either high-pressure or cryogenic storage solutions, which subsequently increase infrastructure costs. It is also demonstrated that retrofitting or replacing the existing infrastructure for hydrogen transport can lead to leakages [64][65][66].…”

“…In [65], the use of hydrogen in German gas distribution grids, comparing the continuation of natural gas, transitioning to synthetic natural gas, and shifting to hydrogen, is evaluated. The study highlights the necessity of region-specific modeling for distribution network transitions, indicating that the current value of existing gas infrastructure might be overestimated.…”

“…Certain studies, possibly due to oversight or methodology limitations, do not fully examine the complexities of the energy system (e.g., the impact of increased electrification on peak demand). An omission or oversimplification of the interaction between the electricity and gas/hydrogen sectors could consequently yield an incomplete or biased viewpoint [63][64][65][73][74][75][76]85,86,100,103]. In Figure 6, an example of the interaction between different energy vectors is presented based on the work in [116].…”

“…In this context, if hydrogen infrastructure is required at scale to enhance resilience, its costeffective role in heating becomes more attainable, as heating can then facilitate the efficient utilization of this infrastructure. Research that does not include resilience as a core parameter might fall short of capturing the comprehensive array of benefits that hydrogen can offer, specifically for extreme events or emergencies [58,[63][64][65][66]78,82,85,92,94,95,100,102,105,107].…”

Hydrogen is an emerging technology changing the context of heating with cleaner combustion than traditional fossil fuels. Studies indicate the potential to repurpose the existing natural gas infrastructure, offering consumers a sustainable, economically viable option in the future. The integration of hydrogen in combined heat and power systems could provide residential energy demand and reduce environmental emissions. However, the widespread adoption of hydrogen will face several challenges, such as carbon dioxide emissions from the current production methods and the need for infrastructure modification for transport and safety. Researchers indicated the viability of hydrogen in decarbonizing heat, while some studies also challenged its long-term role in the future of heating. In this paper, a comprehensive literature review is carried out by identifying the following key aspects, which could impact the conclusion on the overall role of hydrogen in heat decarbonization: (i) a holistic view of the energy system, considering factors such as renewable integration and system balancing; (ii) consumer-oriented approaches often overlook the broader benefits of hydrogen in emission reduction and grid stability; (iii) carbon capture and storage scalability is a key factor for large-scale production of low-emission blue hydrogen; (iv) technological improvements could increase the cost-effectiveness of hydrogen; (v) the role of hydrogen in enhancing resilience, especially during extreme weather conditions, raises the potential of hydrogen as a flexible asset in the energy infrastructure for future energy supply; and finally, when considering the UK as a basis case, (vi) incorporating factors such as the extensive gas network and unique climate conditions, necessitates specific strategies.
