China's largest listed company for producing hydrogen from electrolyzed water.

1. Baofeng Energy (600989): On April 20, 2020, the company said on the interactive platform that the integrated solar electrolyzed water hydrogen production project initiated by the company is the largest integrated renewable energy hydrogen production and energy storage project in China. The project mainly includes the construction of 20,000 m3/h electrolyzed water hydrogen production device and supporting public and auxiliary facilities, 200MWp composite photovoltaic power station, Ningdong Energy Center 1 demonstration station (including 2000kg/ day hydrogenation, 1 10,000 m3/ day gas filling, 1 10,000 tons/year gas filling and 8 charging piles).

2. Foton Motor (600166): June 2020 10, interactive platform reply: The company attaches importance to the development of hydrogen energy, including technology development, market development and personnel training, and both heavy and light hydrogen energy trucks are included in the plan. At present, the company's hydrogen fuel heavy truck products are in the product development stage, and are independently developing fuel cell heavy trucks with long driving range, high load and high speed.

3. Dongfang Electric (600875): In 2019, the first batch of hydrogen energy and fuel cell production lines in the west of the company were successfully put into production, the development of hydrogen energy intercity buses and logistics vehicles was completed, and the first international conference on hydrogen energy and fuel cell industry in Chengdu was successfully held, with increasing industry influence.

1. Hydrogen production

Global: natural gas (48%), alcohol (30%), hydrogen production from coal (18%) and hydrogen production from electrolytic water (4%).

Japan: The proportion of electrolyzed water is as high as 63%

China: Hydrogen production from coal (62%), natural gas (65,438+09%), industrial by-products (65,438+08%) and electrolyzed water (65,438+0%).

Hydrogen production cost: hydrogen production by electrolysis of coke oven gas: simple process, no pollution and high purity, suitable for proton membrane fuel cells. Disadvantages are high cost, high power consumption, and the possibility of large-scale popularization and application is temporarily unavailable.

Sources of electricity for electrolytic hydrogen production: low-valley electricity, large-scale industrial electricity and renewable energy waste electricity.

2. Storage and transportation of hydrogen energy

Hydrogen storage: high pressure hydrogen storage (mainstream), liquid hydrogen storage (aerospace field), metal oxide hydrogen storage (laboratory stage), carbon-based material hydrogen storage and chemical hydrogen storage.

Transportation: The main transportation modes are high-pressure gas transportation, liquid hydrogen transportation, organic liquid hydrogen transportation and solid hydrogen transportation.
