Life cycle environmental and economic analyses of a hydrogen station with wind energy

摘要: Abstract This study aimed to identify the environmental and economic aspects of wind-hydrogen system using life cycle assessment (LCA) costing (LCC) methodologies. The target H 2 pathways are pathway water electrolysis (WE) with wind power (WE[Wind]) WE by Korean electricity mix (WE[KEM]). Conventional fuels (gasoline diesel) also included as fuel advantages over conventional fuels. key issues in transportation sector analyzed terms fossil consumption (FFC), regulated air pollutants (RAPs), abiotic resource depletion (ARD), global warming (GW). costs consist well-to-tank (WTT) tank-to-wheel (TTW) costs. Moreover, two scenarios predict potential improvements offered energy-powered hydrogen stations. In LCA results, WE[Wind] is superior other all categories. LCC results show that projected WTT cost savings WE[KEM] compared gasoline US $ 0.050 0.036 per MJ, respectively, because will not be subjected any tax according Energy Policy 2015. Although incur high capital owing required investment cell vehicles (FCVs), they have lower well-to-wheel (WTW) than those due FCV efficiency utilization stage. WTW for higher 12,600 10,200, respectively. demonstrated future competitiveness both aspects. stage, point-of-sale produced plant (WPP) cannot controlled wind-powered production fluctuates considerably depending on wind. However, use a station enables stable management provides greater profit present since can used residual sold Korea electric corporation (KEPCO). If 5% substituted FCVs via 2015, CO emission reduced 2,876,000 tons/year annual 8559 million. Thus, operation stations encourage introduction into market.
