Waste to methanol plant development

Maire Group subsidiary MET Development, together with Eni and utility company Iren Ambiente, have started the permitting process for a renewable methanol and hydrogen plant at Eni’s refinery in Sannazzaro de’ Burgondi near Pavia. The plant will be developed using NextChem’s NX Circular™ technology, which allows the plant to convert waste by generating syngas, which is subsequently used to produce high quality sustainable fuels and chemicals. Once completed, the plant will be able to convert approximately 200,000 t/a of non-recyclable waste supplied by Iren’s waste management unit Iren Ambiente into synthesis gas. This will in turn be converted to produce up to 110,000 t/a of renewable methanol, as a potential fuel for decarbonisation of the maritime sector. It will also produce up to 1,500 t/a of hydrogen, which could be used in refinery processes, reducing CO2 emissions compared to fossil-generated hydrogen, or, alternatively, for sustainable mobility in road and rail transport. The plant will also recover 33,000 t/a of inert granulate, which can be used for the cement industry. The plant will use infrastructure and services already available at the refinery to optimise costs.

Fabio Fritelli, NextChem managing director, commented: “This project is a unique opportunity to combine environmental sustainability and economic growth. Italian ports will be among the first in the world to be able to benefit from the new environmentally friendly fuel required by international regulations.”

CIMC Enric commissions biomethanol project

CIMC Enric Holdings Ltd says that it has commissioned China’s first large-scale biomethanol facility in Zhanjiang, Guangdong Province, marking a major step forward in the decarbonisation of global shipping and clean fuel supply chains. The project, developed by CIMC Enric and its subsidiaries, is designed as a fully integrated closed-loop system converting forestry residues into green methanol for use as marine fuel. With an initial annual capacity of 50,000 t/a, it is the country’s first commercial scale green methanol plant, and is backed by the port of Zhanjiang and abundant local forestry wastes.

World’s largest integrated green hydrogen-ammonia-methanol project

The first 320 MW phase of what China Energy Engineering Corporation Ltd says will ultimately become the world’s largest integrated green hydrogen-ammonia-methanol project HyFlow has officially begun operation in Songyuan City in Jilin Province. With a total investment of nearly $4.30 billion, the Songyuan project uses a “wind-solarhydrogen-ammonia-methanol” integration model, creating an industrial chain that includes hydrogen production and storage, as well as hydrogen-derived chemicals such as ammonia and methanol, hydrogen energy equipment, and scientific research. The project eventually plans to develop 3 GW of renewable energy capacity from wind and solar power, alongside a target production capacity of 800,000 t/a of green ammonia and methanol. The annual production of green hydrogen in the project’s first phase is expected to be equivalent to approximately one-fifth of China’s current total annual green hydrogen production.
