The Haber process is already operating close to maximum possible efficiency, so there are no big gains to be had.
- pjc50 3y agoCurrently the Haber process uses hydrogen. Mostly from natural gas. So there's interest in processes which don't have CO2 as a byproduct.
- alvah 3y agoIt seems much more likely this breakthrough will come from alternative methods of extracting hydrogen, than re-inventing the Haber process.
- pjc50 3y agoI don't normally ask for explanations of downvotes, but all three sentences in this seem uncontroversial?
- wongarsu 3y agoAll of them seem like non-sequiturs, they have little relation to each other or to the comment they reply to. The haber process doesn't require that the hydrogen comes from natural gas, and if you use other hydrogen sources and clean energy doesn't release CO2. From what I understand the popularity of natural gas simply comes from natural gas being one of the cheapest sources of energy. If you have cheap electricty you can just run a fuel-cell backwards, or electrolyse water. Electricity just happens to be more expensive than natural gas. Other processes will hit the same problem, since the overall energy requirement is the same. Whatever process we find needs the energy from somewhere.
