Green Methanol manufacturing from CO2

Introduction

The TRISKELION project will build an innovative e-Methanol production plant in Mugardos (Galicia, Spain). This renewable product will be synthesized in an innovative single reactor from CO2 (captured from the flue gas of a combined heat and power plant) and renewable hydrogen (produced from electrolysis). The relative greenhouse gas (GHG) emission avoidance is estimated to be around 137% compared to the reference scenario.

Project Innovation

The innovation of the project comes from the combination of different technologies with varying degrees of technological maturity. The proposed capacity is significantly larger than any demonstration project in Europe, which will increase the System Readiness Level (SRL) and Technology Readiness Levels (TRL) of the plant. This enables it to reach a commercial level that allows for its replication in different sectors.

Production Capacity

The system has been designed to produce 40,000 tonnes per year of e-Methanol. It will also recover 59,643 tonnes per year of liquefied green oxygen from the electrolysers, which will be later purified and liquefied to ensure it is valuable.

Renewable Energy Supply

Electricity from renewable sources, through Power Purchase Agreements (PPAs), will be supplied to the entire system, ensuring a renewable and continuous power source during the 8,000 hours/year of operation. The excess water stream generated in the e-Methanol distillation will be reused directly in the electrolyser, minimizing the total water quantity required.

Environmental Impact

The project will avoid approximately 860,282 tonnes of CO2 equivalent of absolute GHG emissions during the first ten years of operation.

Market Integration

This project will develop solutions and products (e-Methanol and renewable oxygen) to be deployed in the market, integrating different technologies and systems. It aims to avoid the use of fossil-based raw materials by utilizing secure (in time) and stable (in quality) renewable energy sources. In addition, the project will maximize energy integration throughout various process units.

Contribution to European Objectives

TRISKELION will contribute to the European objectives set down in the REPowerEU communication, particularly by producing a synthetic fuel, e-Methanol, that will reduce fossil fuel consumption in industry and transport.

Socioeconomic Impact

The project will also have relevant regional socioeconomic impacts, creating 35 direct jobs and 70 indirect jobs, with a potential for scalability and replicability of the technology.
