Green Hydrogen cost reduction.
Green hydrogen is still 2-3 times more expensive than blue hydrogen. This report goes into detail about what’s involved in getting green hydrogen from $4/kg to $1/kg to make it competitive for most use cases.
Summary
- Cost of the renewable electricity needed to power the electrolyser unit. (India already has the lowest solar energy costs)
- Electrolyser Costs
a) Electrolyser design and construction: Increased module size and innovation with increased stack manufacturing
b) Economies of scale: Increasing stack production to automated production in GW scale manufacturing facilities can achieve a step-change cost reduction. - Electrolyser Efficiency
- Lifetime of Electrolysers
- Full load hours
- Cost of Capital
