“…The study In [98] presents a cost-benefit analysis comparing heat pumps and condensing boilers using natural gas and green hydrogen for individual heat supply. The analysis finds that heat pumps are generally more efficient and cost-effective than green hydrogen, suggesting green hydrogen be reserved for applications where other decarbonization alternatives are not available.…”

“…Factoring in the incorporation of negative emission technologies, such as BECCS and DACS, could increase the significance of hydrogen within the future energy decarbonization. Disregarding these technologies can specifically reduce the role of blue hydrogen and hence, limit the hydrogen supply for a range of applications [59][60][61]85,86,88,90,93,98,100,101,103,106].…”

“…For instance, in Germany, the utilization of blue hydrogen is not on the net-zero agenda, while in the UK, it can play an important role. In contexts where these unique challenges and targets of the UK are not given due consideration, there is a likelihood that hydrogen's important role in heating will become inadequately represented [56,60,61,63,64,66,[84][85][86][90][91][92]98].…”

“…Focus on the consumer perspective A significant number of studies tend to view the potential of hydrogen solely through the consumer and end-user perspective, and so primarily focus on household costs [61,[73][74][75][76]98,100,103]. While this perspective is undeniably important, it can sometimes overlook the broader system benefits and infrastructural considerations.…”

“…Some studies did not factor in hydrogen production through ATR/SMR plants, especially when produced with CCS, i.e., blue hydrogen, since the policies in the studied region did not permit it (e.g., Germany). However, some of the reviewed references did not give adequate attention to the technological advancements or the expected scalability of blue hydrogen production [59][60][61]85,86,88,90,93,98,100,101,103,106]. Not considering the role of CCS in hydrogen production raises the risk of neglecting the practicality of hydrogen due to concerns with emissions or financial barriers.…”

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.
