2.4 The Research Instruments
9
The case studies of the proposed research can be qualified as exploratory
case studies. The case studies are undertaken before implementing further largescale investigations when there is considerable uncertainty. It is not sure that the
case studies offer renewable energy legal and economic framework for renewable
energy project developers, neither that the case studies have a developed hydrogen
economy.
Case studies are well suited research instrument for the descriptive part of the
research conducted with a positivist research philosophy.
The case studies will answer the secondary questions 3 and 4.
2.4.4 Target Populations/Sampling
Nonprobability samples are used for the expert interviews and the case studies.
2.4.5 Samples of Expert Interviews
The author has the objective to interview five convenience samples of policy
experts, five convenience samples of renewable energy project developers and
five convenience samples of hydrogen off-takers. Following the first interviews,
possible snowball samples will be identified.
For generalization purpose, samples should cover the main regions where large
renewable energy projects are currently developed. For example, experts interviewed could be from different regions such as Europe, North America, or APAC,
enabling the analysis of the phenomenon at a global scale.
2.4.6 Samples of Case Studies
The author plans to conduct the survey on the five targeted countries of the APAC
markets. Those are judgement samples. The countries have been selected based on
their ambitious renewable energy plans and their developed economy favourable
to the consumption of fossil fuel-based hydrogen.
