A new way out for offshore wind power -- hydrogen production from wind power

recently, shell, Siemens and TenneT jointly called on the German government to accelerate the technical research of hydrogen production from offshore wind power, and suggested that bidding for offshore wind power hydrogen production projects should be considered to effectively alleviate the contradiction between the rapid growth of offshore wind power and the slow speed of power construction, so as to promote the development of offshore wind power in Germany

bottleneck

see Europe for global offshore wind power. In addition to the "leader" Britain in Europe, the development momentum of offshore wind power in Germany can not be underestimated. They actively deployed offshore wind power in the Baltic Sea and North Sea economic belt. After several rounds of offshore wind power bidding in 2013, by the first half of 2018, the total installed capacity of offshore wind power in Germany had reached 5355mw, closely catching up with the UK, which ranked first

however, behind the rapid development, there will also be the same dilemma faced by the wind power industry in various countries. Even Germany, which has always been known for scientific planning and rigor, cannot escape, that is, the lagging speed of power construction simply cannot meet the needs of the rapidly expanding offshore wind power transmission. As long as the project is located in Beihai, it will be more or less affected by power rationing, mainly limited by power capacity. Objectively speaking, Germany's initial intention to develop offshore wind power will not change with high mechanical strength, but the construction of offshore transmission system requires a lot of preliminary planning, survey, approval and other work, and the construction period is even longer, which requires the cooperation of all parties, and cannot be achieved overnight

breaking the situation

direct hydrogen production from offshore wind power avoids the difficulties of power system construction, and provides a feasible idea for the development of offshore wind power. Therefore, the above-mentioned companies called for accelerating the development of offshore wind power hydrogen production projects, and suggested that the German government consider carrying out bidding for offshore wind power hydrogen production projects

the three companies that raised questions were representative enterprises in the oil and gas industry, offshore wind power industry and power transmission industry. These companies believe that the implementation of the project bidding of the combination of offshore wind power and hydrogen production technology will promote the development of offshore wind power and renewable energy power in Germany and achieve the goals of the German climate agreement. The adoption of this type of hybrid project can enable Germany to build more offshore wind power without overburdening land-based power, which will help alleviate the long-term problem of power connection on the development of offshore wind power in Germany

offshore wind power hydrogen production mode

this mode is based on a research project called "power to gas" of E-Bridge, that is, to balance the supply and demand of electricity through hydrogen and oxygen production by electricity. In short, hydrogen energy storage is another technical route of energy storage technology, which regulates the peak and valley of power

"power to gas" is not high price and good equipment quality. It uses offshore wind power to produce hydrogen locally, and then transports the hydrogen back to land for power generation and transportation fuel, thus reducing the dependence on the transmission network; It can also be combined with the use of gas transmission pipelines of oil and gas companies to combine new energy power generation with the resources of original gas manufacturers to speed up the preparation of industrial plans, so as to achieve the goal of carbon reduction and improve environmental acceptance

the advantages of this mode are obvious:

the new offshore wind power project does not need to build a new offshore transmission system, and is not restrained by the power company

offshore wind power can be built near oil and gas platforms or oil and gas pipelines to reduce transmission losses and may also reduce project investment costs

there are abundant raw materials for hydrogen and oxygen production from offshore wind power, and the offshore materials used for hydrogen production can be said to be "inexhaustible"

friendly to the environment, both natural gas and oil are carbon containing fossil energy, and the product of hydrogen combustion is water, which truly realizes zero emissions

how to do next

although the idea is very good, the development of this model still needs further research, including offshore hydrogen production technology, hydrogen storage technology, environmental issues and the safe coexistence of gas platforms, and other issues. In addition, the business model also needs further research

therefore, the three companies are currently actively studying, and suggest that the German government carry out research on the bidding mode of offshore wind power and electric hydrogen production projects, and cultivate this new renewable energy utilization mode as soon as possible

innovation promotes development

compared with Norway's sea wind gas combination mode, this mode is a further business innovation mode, which is believed to promote the development of offshore wind power industry. According to E-Bridge, between 2026 and 2030, the potential capacity of offshore wind power projects adopting this mode can reach 900 MW, and the pilot bidding process may be launched in 2022
