E-Methanol Enables Hydrogen Economy, Adds Value to

The cost of e-methanol—that is, methanol produced from green hydrogen and CO 2 —strongly depends on the cost of green hydrogen and, to a lesser extent, on the cost of carbon. According to the International Renewable Energy Agency (IRENA), it is estimated to cost between USD $800-$1,600/metric ton, assuming CO 2 is sourced from bioenergy with carbon
