E-methanol explained

E-methanol is made by combining captured carbon dioxide with hydrogen produced by electrolysis using renewable electricity. It is the most technically elegant answer to low-carbon methanol and the most expensive, and its availability is constrained by things that have nothing to do with methanol: the cost of renewable power, the pace of electrolyser deployment, and access to a suitable CO₂ stream.

For most industrial buyers today it is a small, premium and heavily committed supply, most of it heading to shipping. That is worth understanding even if you are not buying it, because it shapes where the low-carbon market goes next.

The two inputs

Renewable hydrogen

Water is split by electrolysis using renewable electricity. This is the expensive half. The cost of the resulting hydrogen is driven overwhelmingly by the price of the electricity and the utilisation of the electrolyser, which is why e-methanol projects cluster where renewable power is cheap and abundant — and why offshore wind regions have become natural candidates.

Captured carbon dioxide

CO₂ is captured from a point source such as a biogenic process, an industrial flue gas, or directly from the air. The two streams are then combined over a catalyst to synthesise methanol, using chemistry closely related to conventional synthesis.

The cost structure

E-methanol is expensive for reasons that are structural rather than temporary inefficiency.

• Electricity dominates. Producing hydrogen by electrolysis is energy-intensive, and the electricity price flows almost directly into the methanol cost.
• Utilisation matters as much as price. An electrolyser running intermittently on cheap surplus power has low energy costs and poor capital utilisation. Balancing the two is the central design problem.
• Carbon capture has its own cost curve. Direct air capture is considerably more expensive than a concentrated biogenic point source, and the choice affects both cost and claim quality.
• Scale is not there yet. Projects are first-of-a-kind, financed against long-term offtake, which is why announced capacity is typically contracted before it exists.

The result is a product priced well above bio-methanol, which is itself priced well above conventional. For most industrial applications, bio-methanol is the practical low-carbon option today and e-methanol is the thing to watch.

What to establish before signing

1. The certification scheme and certificate reference. As with any low-carbon claim, the scheme name and reference are the claim — see certification and mass balance.
2. The CO₂ source. Biogenic, direct air, or fossil point source. This materially affects how your own reporting framework treats it.
3. The electricity basis. Whether the renewable power is physically matched, contractually matched, and on what temporal granularity. This is an area of active regulatory development.
4. Delivery reality. Whether the volume exists now or depends on a project reaching final investment decision. An offtake from an unbuilt plant is a different risk from a supply contract — the pipeline page shows how often those dates move.
5. The same hazards apply. E-methanol is methanol. Flash point, toxicity and regulatory duties are unchanged.
