The State Grid Jiaxing Power Supply Company in Jiaxing City, China, achieved a significant breakthrough in hydrogen energy with the approval of the 'Carbon Inclusion Methodology for the Use of Hydrogen Energy Power Generation Vehicles in Jiaxing City'. This methodology passed an expert review organized by the Jiaxing Municipal Ecology and Environment Bureau, becoming the first in the field of hydrogen energy power generation vehicles. The methodology focuses on quantifying emission reduction behaviors through carbon inclusion, promoting energy conservation, and supporting the hydrogen energy industry. It aims to reduce greenhouse gas emissions by using hydrogen energy power generation vehicles instead of diesel ones in Jiaxing city. Jiaxing City is actively working towards the 'dual carbon' goal and has released plans to further develop the hydrogen energy industry, targeting a manufacturing output value of 20 billion yuan by 2027. Initiatives include increasing hydrogen refueling stations and promoting the use of hydrogen energy vehicles and transportation tools. The city is a pioneer in Zhejiang province, with Jiashan county serving as a demonstration site for hydrogen fuel cell vehicles. State Grid Jiaxing Power Supply Company has played a vital role in promoting hydrogen energy application in the city, especially through the development of an 'all-zero carbon' composite hydrogen energy storage emergency power supply vehicle, which has been used in major events like the Asian Games. The company plans to continue supporting the city's green and low-carbon development by focusing on carbon inclusion certification and emission reduction trading.
