Figure 12.
The three plots are Hydrogen Refuelling Station, Hydrogen Demand, and Vehicle Stocks. Hydrogen Refuelling Station has Time Period on the horizontal axis from 2020 to 2034 and Number of Stations on the vertical axis from 0 to 60,000, at intervals of 10,000. Four series represent Scenario 4 Increase 10 per cent, Scenario 4 Increase 20 per cent, Scenario 4 Increase 30 per cent, and Current Level. All series increase throughout the period, with the rate of increase becoming progressively steeper. By 2034, the 10 per cent series reaches about 56,000 stations, the 20 per cent series about 49,000, the 30 per cent series about 43,000, and Current Level about 39,000. Hydrogen Demand has Time Period on the horizontal axis from 2020 to 2034 and Million Tonnes on the vertical axis from 0 to 6, at intervals of 1. Four series represent Scenario 4 Increase 10 per cent, Scenario 4 Increase 20 per cent, Scenario 4 Increase 30 per cent, and Current Level. All increase from near 0 in 2020 with progressively steeper rises. By 2034, the respective values are approximately 5.6, 5.0, 4.4, and 3.9 million tonnes. Vehicle Stocks has Time in years on the horizontal axis from 2020 to 2035 and Percentage on the vertical axis from 0 to 100, at intervals of 20. The legend contains E V, F C E V, and I C E vehicle stock series for Scenario 4 increases of 10, 20, and 30 per cent and Current Level. The E V series increase from near 0 per cent in 2020 to about 67 per cent in 2035. The F C E V series increase from near 0 per cent to approximately 34 to 38 per cent. The I C E series decline from about 100 per cent in 2020 to approximately 22 to 34 per cent in 2035.Scenario 4
