Abstract: Hydrogen energy has become the key force to accelerate low-carbon transition in the areas of industry, building and communications. Green hydrogen produced by renewable energy electrolytic water technology is regarded as the best option for low-carbon transition of energy thanks to its near-zero emission in the production process. Currently, renewable energy hydrogen production has a high cost and a poor economic performance and calls for extra economic results to promote extension of the related technology. This article elaborates the main international voluntary carbon reduction mechanisms and carbon asset development conditions. It points out that the carbon asset development feasibility of the renewable energy hydrogen production projects requires economic performance of carbon reduction and more financial support. The current carbon-reducing methodology of renewable energy hydrogen production faced some challenges in the Chinese practice, such as instability of new energy powered electricity generation and inadequacy of the existing energy storage facilities in particular. To formulate the carbon-reducing methodology of renewable energy hydrogen production suitable for China’s conditions, the article proposes to set a reasonable proportion of renewable energy application, adopt the default value of baseline that is close to and in line with China’s current conditions and simplify operation for identification of the baseline scenarios.
