Green hydrogen is the foundation of a sustainable carbon-neutral future


His Excellency Saeed Mohammed Al Tayer, Managing Director and CEO of Dubai Electricity and Water Authority, stressed that green hydrogen is one of the pillars of a sustainable future that depends on accelerating the transition to carbon neutrality to support the green economy.

This came in a speech delivered by His Excellency at the “Gastec 2021″ conference and exhibition, hosted by the UAE under the patronage of His Highness Sheikh Mohammed bin Rashid Al Maktoum, Vice President and Prime Minister of the UAE and Ruler of Dubai, may God protect him, and with the support of the Ministry of Energy and Infrastructure, and organized by the « dmg for events.

His Excellency Al Tayer said: “Organizing this pioneering global event highlights the efforts of the UAE, under the wise leadership, in the transition towards a green economy by moving to a new energy landscape in which clean and renewable energy sources are among its most important components, and creating a sustainable carbon-neutral future. In addition to consolidating Dubai’s position as a global center for clean and renewable energy.

Today, the world is witnessing an increasing interest in investing in clean and renewable energy sources, which will change the global energy landscape in the coming years, especially for countries looking to accelerate the pace of economic recovery in the wake of the emerging Corona Virus (Covid-19) pandemic, by shifting from dependence on Fossil fuels are turning into environmentally friendly and relatively low-cost energy sources, including hydrogen.”

Al Tayer explained: “There are three main types of hydrogen, according to the extent to which it is free of carbon, and they are green hydrogen, which is of interest to us in line with the Dubai Clean Energy Strategy 2050, and it is produced through electrolysis using renewable energy sources, and blue hydrogen is produced using fossil fuels with part removal. Most carbon, gray hydrogen is produced using fossil fuels and without carbon removal.

Green hydrogen represents one of the pillars of a sustainable future that depends on accelerating the transition to carbon neutrality to support the green economy. Green hydrogen is receiving increasing global attention in the recent period, as it is a clean fuel that can support global efforts to reduce global carbon emissions, which are considered high costs, and to deal with the issue of change. climate and global warming.

Its objectives are also to develop the green mobility sector, reduce carbon emissions in various industries, and use it in the transportation sector; In addition to producing electrical and thermal energy, we can thus contribute to reducing carbon dioxide emissions.”

His Excellency Al Tayer continued, “The world is witnessing an expansion in the implementation of pilot projects for hydrogen production, which is likely to be a nucleus for commercial expansion in its use in many applications in the fields of industry, transportation, housing and others, with governments continuing to support scientific research and development efforts, raising efficiency and continuously reducing the cost of production. hydrogen, and offering packages of financial and regulatory incentives for start-up hydrogen production projects, to make it more cost- and logistically attractive.

It is expected that green hydrogen will contribute to reducing the costs of producing clean energy and raising the efficiency of its production, and to be able in the future to compete with hydrogen from fossil fuels and the associated carbon emissions.

However, given the current level of maturity of green hydrogen production and uses technologies, we still need to make significant efforts in research and development of electrolysis techniques and fuel cell applications on a large scale, and study the technical and economic feasibility of hydrogen combustion technologies, in addition to ensuring the technical and economic feasibility of hydrogen storage The long-term”.

His Excellency Al Tayer explained that the “electrolyzer” technologies need more maturity and development, and that the units’ sizes need to rise to 100-300 megawatts, compared to the typical units deployed today, which range in size from 5 to 10 megawatts, as such development will help Reducing the cost of the electrolyzer by more than 50%, in addition to increasing the energy efficiency required to produce each unit of hydrogen, to more than 70%.

Global hydrogen demand is expected to increase from about 75-85 million metric tons in 2020 to about 580 million metric tons in 2050.

Global studies indicate that if the use of low-carbon hydrogen expands in appropriate applications, and if global emissions are in line with the Paris climate agreement’s goals to keep global temperature rise below 2°C, the size of the global market for low-carbon hydrogen and hydrogen-based synthetic fuels could potentially increase. It will reach $1 trillion by 2050. Among the countries working on it are China, the United States, India, Russia, Brazil, Germany, and South Africa.

His Excellency Al Tayer continued: “Dubai has provided a successful model for designing the future and ensuring high levels of preparedness to face unexpected challenges. In line with this success, DEWA continues its efforts to achieve the insightful vision of the wise leadership, which focuses on anticipating, preparing and planning for future challenges to enhance the UAE’s leading position globally in various fields. His Highness Sheikh Mohammed bin Rashid Al Maktoum, God in 2012 the Mohammed bin Rashid Al Maktoum Solar Energy Complex, the world leader in the production and innovation of renewable and clean energy technologies.

The green hydrogen project, which was inaugurated last May in the complex, is one of the stations of this success that charts the features of a brighter and more sustainable future for us and for our future generations.”

Al Tayer highlighted Dubai’s experience in the field of transition towards renewable and clean energy, as the total production capacity of Dubai Electricity and Water Authority of clean energy increased to about 10% of Dubai’s energy mix, and will reach 13.3% in stages from the end of this year until the end of this year. The first quarter of 2022, as Dubai Electricity and Water Authority is working on diversifying sources of clean energy production to include solar photovoltaic energy, concentrated solar energy, green hydrogen using renewable energy, and stored hydro energy, in addition to studying the exploitation of wind energy.

Al Tayer added: “The green hydrogen project, which was implemented in cooperation between DEWA, ​​Expo 2020 Dubai and Siemens Energy, at the Authority’s Research and Development Center in the Mohammed bin Rashid Al Maktoum Solar Park, is the first project of its kind in the Middle East and North region. Africa to produce green hydrogen using solar energy, and the plant is designed and built to be able to accommodate future applications and test platforms for various uses of hydrogen including energy production, transportation and industrial uses.

The production of green hydrogen is part of DEWA’s efforts to support the Dubai Clean Energy Strategy 2050 to provide 75% of the energy production capacity from clean energy sources by 2050. This project contributes to paving the way for building a green economy based on clean energies, including green hydrogen, which Some describe it as the fuel of the future, and it will play an important role not only in the global energy mix, but also in mitigating the effects of global warming.

In order to achieve the objectives of the Dubai Green Mobility Initiative 2030, which aims to stimulate the use of sustainable means of transportation, in addition to the national system for hydrogen vehicles, which aims to develop the hydrogen economy in the UAE, open local markets to hydrogen vehicles and encourage an increase in the number of environmentally friendly vehicles; The Dubai Electricity and Water Authority, in partnership with the Emirates National Oil Company (ENOC), is studying the construction of a station to provide hydrogen fueling service.”

His Excellency concluded by saying: “The hopes are high for green hydrogen, and thanks to the contribution of the efforts of the Research and Development Center of the Authority, we believe that the production of green hydrogen will take the same positive path that solar photovoltaic, wind energy and batteries follow.

In our journey towards achieving zero carbon emissions, green hydrogen plays a particularly important role in decarbonizing industry, integrating renewable energy sources in power generation and transportation sector, etc. I am sure that organizing this edition of the Gastec Conference in Dubai will add To the list of successes and achievements of the conference over the past years, and will contribute to supporting the energy sector, strengthening the pillars of sustainability, accelerating the transition towards renewable and clean energy, and finding solutions to current and future challenges.
