Netherlands: The world's first offshore wind power hydrogen production demonstration project

The PosHYdon project in the Netherlands is the world's first offshore wind power hydrogen production project. The PosHYdon project based on the Q13a platform is the world's first offshore wind power hydrogen production project. It is jointly undertaken by a number of companies and institutions in the Netherlands to promote emission reduction and establish a new energy model in the North Sea. Nepture Energy's Q13a platform is the first fully electrified oil and gas platform in the North Sea in the Netherlands. It will be transformed into a hydrogen production platform in the PosHYdon project. The containerized hydrogen production equipment is small in size and can be accommodated by most offshore platforms. At this stage, the platform's power is temporarily supplied by the onshore grid via submarine cable connections (and simulated by fluctuating offshore wind power generation), and will be supplied by nearby offshore wind farms in the future.

The PosHYdon project aims to study hydrogen production from offshore wind power, innovative technology, and promote its application in the Netherlands. In the future, electrolysis equipment will be installed on other offshore platforms near offshore wind farms in the North Sea. By combining the three industries of hydrogen, natural gas, and wind power, we can provide green energy for human society and realize energy transformation.

Belgium: Expected to build the world's first commercial offshore wind power hydrogen production project

A few days ago, Belgium released a plan for an offshore wind power hydrogen production project called "Hyport Oostende". According to its schedule, it is expected to become the world's first commercial offshore wind hydrogen production project to be put into operation. The project was jointly developed by offshore engineering giant DEME, investment agency PMV and the port of Ostend in Belgium, and was implemented in the port of Ostend. The project is divided into two phases, the first phase is to develop a 50MW demonstration project, and the second phase is to develop a larger-scale commercial project to be completed by 2025.

By the end of 2020, about 400 offshore wind turbines will be put into operation in Belgium, with a total installed capacity of 2.26GW. According to Belgium's new sea area plan, an additional 1.75GW will be added, reaching a total of 4GW, which can supply about half of the country's electricity.

France: Launch of the first wind power hydrogen production plan

A French company founded in 2017, Lhyfe, has developed a scheme to use renewable energy to produce hydrogen through electrolysis without connecting to the grid. It has raised 8 million euros and will be established in northwestern France within a few months. France's first wind power hydrogen production demonstration plant. At the same time, the company plans to deploy its concept to offshore wind power projects by 2025.

Germany: The latest offshore wind power generation strategy, invests 2 billion euros

According to a hydrogen energy development strategy being drafted by the German Ministry of Economy and Energy, Germany is considering designating some offshore wind farms specifically for the production of green hydrogen in the offshore wind power competition. For the domestic hydrogen energy market in Germany, the draft proposes to develop at least 3GW of electrolytic hydrogen production capacity by 2030, and green hydrogen accounts for 20% of the total hydrogen supply. This is a difficult goal. The total installed capacity of offshore wind power in Germany is 7.5GW, which was established over the past 10 years.

34 specific measures for the development of hydrogen energy have been proposed, and this draft is currently under consideration by other government departments. The measures in the draft also include financial support totaling billions of euros, and it is emphasized that Germany should establish a green hydrogen market as soon as possible and be at the forefront of the world. The hydrogen energy strategy is an integral part of Germany's energy reform-the transition from nuclear and fossil energy to renewable energy. In the medium and long term, Germany plans to use hydrogen as an energy source for industries that were difficult to decarbonize, such as transportation, heavy industry, and heating.

Engie's two companies, Tractebel Engineering and Tractebel Overdick, will also build a 400MW offshore wind hydrogen production station in Germany.

China: The first domestic hydrogen production project from wind power

As the first domestic application project for hydrogen production by wind power, the Guyuan Wind Power Comprehensive Utilization Demonstration Project has recently made new progress. According to the news released by the project party, at present, the whole structure of the project and the decoration of the whole building have been completed, the hydrogen production equipment has been installed in place, and the hydrogen production system pipeline is 95% complete. The equipment will be debugged in the next step.

As a key project in Hebei Province, the project has a total investment of 2.03 billion yuan, invested by Hebei Construction Investment New Energy Co., Ltd., and has technical cooperation with German companies such as McPhy and Encon, and introduced German wind power hydrogen production advanced technology and equipment to build in Guyuan County. There are three parts: a 200 MW capacity wind farm, a 10 MW electrolyzed water hydrogen production system and a hydrogen comprehensive utilization system. The project is constructed in accordance with the overall hydrogen energy industry plan of Hebei Province. Part of the hydrogen is used for industrial production to reduce the consumption of coal and natural gas in the industrial hydrogen production industry; the other part will be used when the hydrogen energy-powered automobile industry has the development conditions. Build a network of supporting hydrogen refueling stations to support the development of clean energy powered vehicles in Hebei Province. After the completion of the project, the annual hydrogen production capacity of 17.52 million standard cubic meters can be formed, which is of great significance for improving the wind power absorption capacity of the Bashang area.

Wind power hydrogen production background

Hydrogen production by wind power means that electricity generated by wind is directly converted into hydrogen by water electrolysis hydrogen production equipment. The hydrogen produced by electrolysis of water is convenient for long-term storage. The specific process is: wind power generation-water electrolysis-hydrogen production and oxygen production-hydrogen energy-applied to a variety of industries, such as transportation, industrial thermal processing, and chemical industries.

The International Energy Agency (IEA) and the China Petroleum Institute of Economics and Technology jointly released the report "The Future of Hydrogen-Seizing Today’s Opportunities" in Beijing. It pointed out that under the background of the global energy structure's transition to clean and low-carbon, hydrogen energy is welcoming In the coming period of important development opportunities, the number of hydrogen energy development policies and projects in countries around the world has increased rapidly. Experts at the meeting believed that strengthening policy guidance, breaking technical bottlenecks, reducing application costs, and strengthening international cooperation are important ways to promote the large-scale development of hydrogen energy. The report predicts that with the decline in the cost of renewable energy and the expansion of the scale of hydrogen production, the cost of hydrogen production from renewable energy may drop by 30% by 2030. Fuel cells, fuel supply equipment and electrolyzers (used for electrolysis of water) Hydrogen production) will benefit from large-scale hydrogen production.

Hydrogen production from wind power will increase the utilization rate of wind energy. On the one hand, the consumption of large-scale wind power has always been a worldwide problem, and China’s problems in this regard are even more prominent. China’s wind resources are concentrated, large in scale, far away from load centers, and the resource market is small and difficult to absorb locally. On the other hand, wind power itself has the characteristics of volatility and intermittentness. Wind power grid integration requires the construction of peak-shaving power supplies. The "Three Norths" (Northwest, North China, and Northeast) regions where China's wind power is concentrated have a single power structure and basically no peak shaving capabilities. In addition, insufficient trans-regional power transmission capacity is also an important constraint.

Using abandoned wind to produce hydrogen can increase the scale of wind power installed capacity and provide a new model for wind power consumption. High-density and long-term storage of the hydrogen produced. The use of high-efficiency and zero-emission hydrogen is an important technical approach to solve the problem of wind energy curtailment and improve the continuity and stability of wind energy supply.
