The focus of GH24EU is on promoting the fast development of hydrogen produced only from renewable electricity. This differentiates it from other organisations. These other groups promote both green hydrogen and hydrogen produced from natural gas combined with carbon capture and storage (CCS) to sequester the CO2 that is a by-product of this process. This leads to mixed messages and confused policy recommendations.
The founders of Green Hydrogen for Europe have been active in hydrogen projects for a number of years. They take a practical engineering-based approach towards hydrogen deployment. It is proposed to extend this to the activities of GH24EU. Such an approach is informed by asking seemingly simple questions, such as:
- What works from an engineering point of view for a given green hydrogen deployment?
- Can this be generalised and applied to a sector?
- What do business cases look like for a given application/technology?
- Who are the counterparties? (i.e. the ones that buy green hydrogen)
- What is the urgency – how soon does Europe need to move to large-scale implementation?
Expressing the above in terms used by Van Quine1:
- What is there? (ontology)
- How do you know? (epistemology)
- Why should I? (or “why shouldn’t I?”)
As van Quine noted, these important questions are regularly asked by 4-year-old children. Well-formulated questions and a forensic approach will, as Wittgenstein2 noted, lead to answers. Unfortunately, the posing of such questions and their corresponding answers are often missing from policy development with respect to green hydrogen.
