- W4381430818 abstract "Renewable-hydrogen (H 2 ) is a key component in Scotland’s decarbonisation plans and its implementation in farming communities can support achieving net-zero goals. HydroGlen, a demonstrative renewable-powered farming community at Glensaugh, is used as a case-study to investigate the potential of renewable-hydrogen in enabling Scotland farms’ energy transition. For our case-study farm, two renewable-hydrogen configurations (Solar-H 2 and Wind-H 2 ) were proposed, sized, and assessed to identify their capability in supplying most of the farm’s residential and commercial demands by clean renewable-energy as well as the transport demands by green hydrogen stored during renewables’ surplus. The effectiveness of the proposed configurations was then assessed against that of the Solar-Wind-H 2 configuration proposed by RINA (RINA 2021). The study started by assessing the currently installed renewables-system in meeting the farm’s demands and results showed that the system can only meet 11% of farm’s commercial and residential demands and none of the transport fuel demands. To allow meeting more residential and commercial demands as well as transport demands, a hybrid Solar-H 2 system was proposed with an additional photovoltaic (PV) capacity that was sized to feed a higher percentage of the demands with renewable power and a hydrogen energy-storage system to store the surplus in PV production in the form of green H 2 to be used in feeding the transport fuel demands. Components of the proposed green-H 2 energy-storage system (electrolyser and storage-tank) were accordingly sized. The effectiveness of the proposed hybrid PV-H 2 configuration was then assessed, and results showed it was capable of supplying 35% of the residential and commercial demands from solar energy and 100% of the transport demands by green H 2 . This generous amount of green H 2 resulted from the plenty PV daytime surplus given that most of the residential demand is not during sun availability hours. A hybrid Wind-H 2 configuration was then proposed, sized and assessed. Results showed that this configuration was capable of supplying most of the residential and commercial demands from wind energy as the wind-generation profile closely matched these demands, and around 44% of transportation fuel demand by green H 2 . The levelized cost of energy (LCOE) was then estimated for each of the proposed hybrid configurations showing that the LCOE for the hybrid PV-H 2 , 0.3 £/kWh, is more cost competitive than that of the Wind-H 2 of 0.4 £/kWh; thus, the hybrid PV-H 2 system was recommended for the farm. Finally, a Simulink model was developed to simulate and assess the operation of the proposed PV-H 2 system given that this has not been considered in RINA study." @default.
