The Basics of Hydrogen

How do we make Green Hydrogen in the desert? What is Hydrogen? OUTPUT Electricity Clean water Hydrogen Oxygen Heat 2.23 x 2.23 x 2.23 Density Density: 89.88 g/m3 1kg at atmospheric pressure ~ 11.125 m3 Melting point Melting point: minus ~ 260 C Solid to Liquid Boiling point Boiling point: minus ~ 253 C Liquid to gas Hydrogen combines with other elements, forming several compounds, including common ones such as water (H2O), ammonia (NH3), methane (CH4), table sugar (C12H22O11), hydrogen peroxide (H2O2) and hydrochloric acid (HCl) INPUT Wind Solar irradiation Seawater 9L of clean H2O per kg of H2 plus ~51L for cooling, water treatment & wastewater disposal 55kWh of electricity is needed per kg of H2 NASA uses hydrogen as rocket fuel to deliver crew to space Hydrogen is an energy carrier with no carbon in it, so when burnt, only produce water Hydrogen is used to make ammonia for fertilizer or explosives, etc Or use to reduce Iron-oxide (Ore) to Iron

What is it about all the colours of Hydrogen? IEA (2019). The Future of Hydrogen Seizing today s opportunities. Prepared for the G20, Japan.

Building our own electrolyser Warning: Do not do this at home without supervision hydrogen is EXPLOSIVE and only need a small spark to make a large and damaging BANG!
