As the world accelerates its transition to clean energy, hydrogen has emerged as a promising solution for decarbonising industries, transportation and power generation.
Governments and corporations alike have invested billions into hydrogen projects, positioning it as a key pillar of the energy transition. However, significant challenges remain, particularly in costs, policy frameworks and technological advancements. To assess whether hydrogen can truly deliver on its promise, industry leaders weigh in on the realities of this evolving sector.
The cost challenge – green versus blue versus grey hydrogen
One of the most significant barriers to widespread hydrogen adoption is cost. Hydrogen production is categorised based on its environmental impact – grey hydrogen (produced from natural gas without carbon capture), blue hydrogen (similar to grey, but with carbon capture and storage), and green hydrogen (produced using renewable energy via electrolysis).
Currently, grey hydrogen remains the cheapest option at around $1.50 per kg (€1.37), while blue hydrogen costs approximately $2 to $3 per kg (€1.83-€2.75). In...
