Abstract
This is an integrated literature review (work in progress) to develop a conceptual framework for green hydrogen technology adoption. For this, we are in the process of reviewing the previous research on the theory of planned behavior, the technology acceptance model, and the cognitive appraisal theory in energy transition studies. The methodology is finalized, but the data collection is currently a work in progress. This paper will contribute to the adoption theory for niche energy markets such as green hydrogen and will help the practitioners develop business cases through the examination of potential endogenous and exogenous factors that affect the adoption in different ways.
