First of all, due to the corresponding the market price of woody biomass feedstock as well as the revision of LCI data in public on the construction materials, the cost and CO₂ emission are revised as 3 yen/MJ, 2 g/MJ respectively. In addition, by investigating the hydrogen production process of pressurized alkaline water electrolysis with PV power supply, the cost and CO₂ emission are newly obtained as 14 yen/MJ, 20 g/MJ as respectively.
　Next, with considering four types of carbon-free hydrogen delivery systems such as 1) Compressed gas cylinder (CSD), 2) Gas Pipeline (PL), 3) Liquid Hydrogen (LH), and 4) Organic Hydride (MCH) and two different users of (a) at FCV dispenser and (b) at Power Plant, costs and CO₂ emissions at the end of supply chain are investigated under the two types of energy supply conditions (Case A: external energy supply and Case B: self-energy supply). We concluded that the self-energy supply condition of Case B should be essential in order to obtain the carbon-free hydrogen at the end point of utilization. In case of FCV user, delivery system of PL and CSD are dominated with results of cost and CO₂ emissions in 9.5 yen/MJ, 9g CO₂/MJ respectively and in case of Power plant, PL is dominated in 4 yen/MJ and 4 gCO₂/MJ respectively.
