Description
LCI of solution mining for the future storage of 1 kg of hydrogen. Includes mostly the water demand, the water injection and the brine pumping. We use tap water for now, which is probably wrong. The salt cavern is assumed to be 500,000 m3 large. The available hydrogen amount is 4,000 tons per year, with a lifetime of 40 years, for a total capacity of 6,350 tons per year. Hence the inputs are normalized by 4,000 tons * 40 years. Here are some additional parameters. Water demand 10 m³/m³ (Niquet, 1978), Water demand, total 5,000,000 m³, Capacity pump 570 kW (van Ohlen, 2015), Efficiency pump 76 % (Flowserve, 2015), Pumping rate, water 250 m³/h (van Ohlen, 2015), Time for solution mining 20,000 h, Electricity demand pump 750 kWh/h, Electricity demand, total 15,000 MWh
