E-Methanol is okay as a carbon neutral fuel and solvent. At 50-60% efficiency it makes an excellent fuel to create from electricity. But it is still a long way from competing with battery and pumped hydro. It's fuel cell efficiency is only 30% with current technology after the 40-50% losses from the creating of the fuel itself. You can buy a lot of transmission wire at that price point.

All of these technologies illustrate how obscenely difficult it will be to put the carbon genie back in the bottle and what a miracle lithium chemistry batteries really are.

But I guess you can make a lot of methanol in summer and burn it in winter, storing it cheaply for months. Batteries so far seem maybe ok at balancing diurnal power generation / use patterns but not seasonal storage.
Yeah, it is definitely not a bad idea for heating fuel, feed chemical, racing fuel, jet fuel, etc... Just replacing the natural gas produced methanol would be nice. However, wind energy has high availability in the winter and batteries would make up for blizzards and shortfalls. Canada is having a lot of good results from wind energy. In addition, they make a ton of energy from hydroelectricity.

Every country is different, E-methanol may be a solution for a few places. However it is not something I would personally invest in.

North European winters are dark, cloudy and often windless, not for 6 hours but for days at a time.
