ASTURIAS H2 VALLEY

Introduction

The Asturias H2 Valley project consists of a first-of-a-kind Power-to-Hydrogen Hub to produce and supply renewable hydrogen, with the overall objective to decarbonise the economy of the region of Asturias, Spain. The project aims to develop a renewable hydrogen plant with 150 megawatts (MW) of electrolysis capacity by repurposing the site of Aboño’s existing coal power plant, aiming to achieve 99.98% relative greenhouse gas emission avoidance compared to the reference scenario.

Project Viability

The project will demonstrate the viability of a fully integrated hydrogen production and distribution process, optimised on the availability of renewable energy (wind and solar) and on demand from off-takers from multiple sectors. A project of this scale has not been demonstrated before.

Infrastructure Repurposing

In the process of the gradual phasing-out of the coal power plant, the hydrogen plant will repurpose the existing installations and infrastructure to:

1. Lower the initial investment costs.
2. Reduce the environmental impact (as it is not necessary to install new electricity supply infrastructures, process and cooling water supply systems, or effluents treatment plant and network, among others).
3. Reduce administrative processing and permitting times.

The project will not only increase circularity but also provide an industrial-size technical demonstration for projects at other sites in transition to emulate.

Environmental Impact

Moreover, the project will avoid consuming around 650 gigawatt hours (GWh) of fossil fuels every year, the equivalent of the annual emissions of more than 45,000 Spanish households. Overall, the project plans to avoid absolute greenhouse gas emissions of 1.3 million tonnes of CO2 equivalent over the first ten years of operation.

Contribution to Climate Strategies

Through many of its planned activities, the project will strongly contribute to several EU and national climate-related strategies and goals, such as:

• The European Green Deal
• EU Hydrogen Strategy
• Circular Economy Action Plan
• REPowerEU

Additionally, it will follow the Just Transition principles. Achieving 150MW of electrolysis will also directly contribute to the European goals of deploying electrolysis capacity to produce renewable hydrogen.

Job Creation

With a strong alignment with the Just Transition principles, it is estimated that the project will generate 55 direct jobs during its implementation, each with high added value, thus contributing to the maintenance of employment and the reconversion of currently declining industries in the region.

In addition, in the construction phase, more than 400 direct jobs are expected to be generated.

Economic Benefits

The project will benefit the off-takers by reducing their consumption of fossil fuels. It will also contribute to a positive trade balance by reducing imports of coal and natural gas, and will strengthen the position of the region in the fast-growing hydrogen market, through the participation of local companies across its value chain.
