Reply to comment by eat_more_ovaltine in Exxon’s bad reputation got in the way of its industry-wide carbon capture proposal by Sorin61

Because hydrogen made through electrolysis takes a huge amount more energy than you get out of the resulting hydrogen. This makes it quite expensive.

Also the fact that they always say hydrogen can be green (which is true), but 95% of the hydrogen we have is made from natural gas which releases all the carbon.

If you have abundant electrical energy, say via a nuclear reactor which can’t be cycled down during low demand like night or some thing like nuclear fusion, it is perfectly valid route
