Hydrogen (H2)

Over the past two decades, colours have been used to differentiate the various forms in which hydrogen is produced.

Grey hydrogen.

Hydrogen is produced from methane reforming and its production entails the emission of CO2 into the atmosphere. Likewise, if the hydrogen is produced from coal, it is called black and if from lignite it is called brown.

Blue hydrogen.

Hydrogen is produced from fossil fuels, but the CO2 is captured and stored. Emissions are significantly reduced with respect to grey hydrogen.

Green hydrogen.

Hydrogen is produced mainly from the electrolysis of water, using electricity generated from renewable sources (solar energy, wind energy, or hydropower).

Importance of hydrogen

- Hydrogen production costs have fallen considerably, and this trend is expected to accelerate.

- The mining sector is of great importance for the development and implementation of hydrogen, and there is a high probability that it will be the first sector where it will be adopted on a larger scale.

- This is due to the size of the vehicles used and the existence of fixed routes.

- The next area in which hydrogen could be developed is in passenger transportation, serving as a complement to battery electric vehicles (BEV) and, in some cases, offering a competitive advantage.

- Hydrogen allows decarbonising activities that are not easy to decarbonise with electricity, such as the production of steel, cement, and petrochemicals.

- Hydrogen is a mean of storing solar and wind energy to help overcome the problem of intermittency.

- Ammonia generation is another alternative for storing low-carbon energy. It can be used as a fuel, energy vector or converted to hydrogen.

Green hydrogen in Mexico

Selection of alternatives for the use of green hydrogen in Mexico

Analysis of sites with current and potential hydrogen demand.

1) Six refineries from the National Refining System. Total hydrogen demand and demand from intermediate distillates hydrodesulphurisation units.

2) Nine open pit mines and one underground mine (mainly in the State of Sonora). Total fleet hydrogen demand and demand for a demonstration project with one vehicle.3) Public transportation in three cities (Monterrey, Guadalajara and Mexico City). Total demand of the BRT fleet and demand for a demonstration project with one vehicle.

3) Public transportation in three cities (Monterrey, Guadalajara and Mexico City). Total demand of the BRT fleet and demonstration project for one vehicle.

4) Injection to the natural gas pipeline network. Up to 3% in volume.

5) Industry (steel, ammonia and methanol). Plants with commercial capacities were considered, with current and potential demand for hydrogen.

General results

- Smaller-scale projects could reduce 1.3 million tCO2e annually, while total hydrogen demand could reduce up to 5.6 million tCO2e annually.

-The greatest potential for emission reductions from green hydrogen use is in oil refining.

-The levelised cost of hydrogen for demonstration projects ranges from US$5.5 per kg to US$8.6 per kg.

-The cost of hydrogen transportation and distribution can increase the final cost of hydrogen by up to 50% depending on the location and type of project.

-The levelised cost of hydrogen is highly dependent on available renewable resources.

-The greatest potential for hydrogen generation and use is in the center and north of the country. The main states are Sonora, Nuevo Leon, Tamaulipas, Chihuahua, Coahuila, Guanajuato, Jalisco, Zacatecas, Puebla and Veracruz.

Use of hydrogen in mining vehicles

- Solar and wind energy generated in mines can be harnessed for hydrogen generation and the replacement of fossil fuel use in mining vehicles through fuel cells.

The most relevant projects at a global scale are the following:

- Anglo American is planning to test hydrogen-based vehicles at its Mogalakwena mine in South Africa.

- Glencore has used a hydrogen-powered renewable energy (wind) storage unit at the Raglan nickel mine in Canada.

- Komatsu will began a hydrogen-based vehicle development program in 2021 for a test unit in 2030.

- Sun Metals announced the addition of a hydrogen production system to its photovoltaic plant located at its zinc refining facility in Queensland. This is intended to produce 140 tons per year of H2 with a 1 MW capacity electrolyser.

Demonstration project at a Mexican mine

Analysis of the use of green hydrogen in a mining vehicle.

Environmental benefits

- The use of H2 would reduce almost 683 thousand kg of CO2 per year.

- Emissions of atmospheric pollutants could be reduced as follows:

9,116 kg per year of NOx, 1,737 kg per year of volatile organic compounds (VOC), 1,823 kg per year of particulate matter with a diameter of 2.5 µm (PM2.5), 1,258 kg of black carbon, and 13 kg of SO2.

Critical implementation path

Critical implementation path

1) Development of a detailed evaluation of the engineering systems required to carry out the project, both from a technical and economic point of view.

2) Establishment of partnerships with companies with expertise in the green hydrogen supply chain.

3) Building the solar photovoltaic system. The estimated planning, installation and operation time in Mexico for a system of the proposed size is 36 months.

4) Adaptation of the fuel cell system for the mining vehicle. Based on the experience of demonstration projects, the design, adaptation and testing time for the mobile unit is 12 months.

5) Development of the hydrogen production and use system. The estimated planning, procurement/testing and operation time for a system of this scale in mining is 24 months.

Public policy recommendations

- Establishment of medium and long-term goals. Commitments to 2030 and 2050 integrated into climate change, energy and industrial policy.

- Supporting demand creation. Establishing policies that set an economic value for hydrogen.

- Reducing investment risks with measures that stimulate private investment due to the existence of uncertainty in demand, and because of the complexity of the supply chain.

- Support for research and development and the implementation of demonstrative projects. Governments have a central role in setting the R&D agenda by backing high-risk projects (new technologies). For projects that are at the upscaling stage or have a lower degree of risk, the government can encourage industry to guide innovation.

- Harmonise standards and eliminate barriers. Remove overregulation and establish common standards to ensure the smooth functioning of the supply chain.

- Work with local communities.
