A decision-support framework for residential heating decarbonisation policymaking

Heterogeneous preferences for living in a hydrogen home: an advanced multigroup analysis

“…148 Fig. 3 demonstrates the multistage research method, which adheres to the following sequence within the paper: reporting results from descriptive statistics and one-way analysis of variance (ANOVA) tests in Section 6.1; carrying out the measurement model assessment for each sub-group in Section 6.2; conducting the measurement invariance test of composite models (MICOM) procedure in Section 6.3; evaluating the structural model in for each subgroup and analysing the difference between path coefficients via PLS-MGA in Section 6.4; extending the assessment via IMPA in Section 6.5; implementing MG-NCA in Section 6.6; and identifying potential sources of consumer heterogeneity in the Discussion section (7) to crystallise the analysis.…”

“…5 Currently, around 38% of the UK's natural gas demand is used for residential heating, 6 which accounts for approximately 14% of national GHG emissions. 7 However, for several years, the residential sector has remained at the margins of system-wide decarbonisation efforts; 8 following a primary focus on phasing out coal power 9 and scaling up renewables to reduce emissions from the electricity sector. 10…”

“…To date, research on domestic hydrogen has applied a techno-economic perspective, 7,34,49 employing tools such as the UK Times Model to examine technology pathways for heat decarbonisation §§For example, Calvillo et al 50 modelled a scenario wherein hydrogen is used in just over 5% of UK households by 2035, before growing to 42% by 2040 and reaching 56.6% by 2050. 44,50 Although primarily concentrated on aspects such as network investments, fuel types, costs, and emissions, 50 forecasters also recognise that factors such as demographics, social habits, public views towards heating, and underlying levels of acceptability will influence domestic energy demand and market developments.…”

“…However, ahead of a potentially 'critical juncture' 42 in the UK's energy future, 43,44 which could shape the feasibility of developing a national hydrogen economy 45 researchers are yet to examine the role of consumer heterogeneity 41,46,47 in shaping potential market acceptance for 'hydrogen homes'. 38,48 To date, research on domestic hydrogen has applied a techno-economic perspective, 7,34,49 employing tools such as the UK Times Model to examine technology pathways for heat decarbonisation. § 44,50 Although primarily concentrated on aspects such as network investments, fuel types, costs, and emissions, 50 forecasters also recognise that factors such as demographics, social habits, public views towards heating, and underlying levels of acceptability will inuence domestic energy demand and market developments.…”
