LONDON, Oct 13 (Reuters) - Spanish energy company Moeve

has become the first external supplier of sustainable aviation

fuel to join Shell's blockchain-based platform for scaling SAF

use, the oil major told Reuters after a deal was signed.

Shell's Avelia platform is a "book and claim" system that

aims to connect airlines, fuel suppliers and corporate buyers.

Avelia, launched in 2022 with Amex Global Business Travel and

Accenture, had facilitated over 41 million gallons of SAF use

across 17 airports as of mid-2025.

Moeve produces SAF from used cooking oil at its La Rábida

Energy Park. It plans to expand overall capacity to 800,000

metric tons a year by 2030.

The global SAF market has struggled to scale despite pressures

to decarbonize the aviation industry. The International Air

Transport Association said in June it expected the amount of

sustainable aviation fuel produced to double in 2025 to reach 2

million tons. However, that would only represent 0.7% of

airlines' fuel consumption.
