Costs of H 2 storage in Europe. Based on our economic analysis, the capital costs of underground hydrogen storage range from $10 million for small storage sites to $1 billion for large storage facilities ( Figure 3 A). Eighty-three percent of the stores have capital costs of less than $100 million ( Figure S4 ).

Our research shows considerable near-term potential for stationary energy storage. One reason for this is that costs are falling and could be $200 per kilowatt-hour in 2020, half today''s price, and $160 per kilowatt-hour or less in 2025. Another is that identifying the most economical projects and highest-potential customers for storage …

The Productivity Commission (2010) estimated that the social costs of water restrictions were approximately $100 million per year relative to introducing scarcity pricing. This was equivalent to approximately $110 per household annually, or more than 15 per cent of the average household''s $658 water bill (NWC, 2009).
