> Hydrogen is one of many available solutions. There are many solutions, but they just don't work. Here's a graph from wikipedia with alternative energy storage technologies [1]. On the horizontal scale it's the storage capacity, on the vertical scale the time horizon. All but 2 technologies have both capacity less than 10 GWh and time horizon less than one month. The only 2 technologies with both higher capacity and horizon are hydrogen and methane (both power to gas). If you care about climate change, hydrogen is superior, for the simple reason that LNG carriers lose methane during transportation, and methane is a very potent greenhouse gas. Hydrogen is superior for 2 reasons: any leakage is inconsequential, and any Exxon-Valdez type of disaster results in zero ecological impact.
