The critical factor that will determine the cost-effectiveness of trade in hydrogen will be whether scale, technologies and other efficiencies can offset the cost of transporting the hydrogen from low-cost production areas to high-demand areas. To produce green hydrogen, renewable energy is converted to hydrogen through electrolysis, and this hydrogen is further processed to increase its energy density. The further processing may take the form of liquefaction, use of liquid organic hydrogen carriers, or conversion to ammonia, methanol, steel or synthetic fuels. The additional conversion steps translate into energy losses and therefore an increase in the cost per unit of […]
