[en] This study assesses the prospects of a hydrogen economy with Chinese characteristics. Against the backdrop of an escalating US-China trade war and the ongoing novel coronavirus (Covid-19) pandemic, key Chinese stakeholders become increasingly interested in moving the hydrogen economy agenda forward. During the first six months of 2020 alone, 37 policies in support of the hydrogen economy have been published by various level governments, including 7 by central government authorities, and 30 by local governments. Shandong alone issued 6 hydrogen supporting policies, followed with 5 by Guangdong. In sum, hydrogen economy development not only gains traction in China, but also is in great danger of overheating. The ambition in China is to expand hydrogen production and create new end-uses: in the transport segment (e.g. 1 million fuel cell electric vehicles - FCEVs - and 1,000 hydrogen refueling stations by 2030), but possibly also, in other hard-to-abate sectors such as steel and cement manufacturing or in the electricity storage segment (Power to X). Hydrogen production from low carbon electricity could bring many benefits, notably to address curtailments of renewable electricity from wind, solar and hydro. It could also be blended into the nation-wide gas grid especially for low-concentration hydrogen (e.g. 5-10%). Until recently, China's interest in developing the hydrogen economy has not been primarily triggered by the decarbonization objective. Nevertheless, on September 22, 2020, Chinese president Xi Jinping announced that China aims to peak national carbon emissions before 2030 and achieve carbon neutrality before 2060. Given the significant amount of carbon emissions reduction implied by the above announcement, hydrogen is now expected to play a much more important role to drastically decrease the country's greenhouse gas emissions (GHG) over time. China's very large hydrogen production from fossil fuels, mainly coal, would make it quite challenging to consider de-carbonizing the current uses of hydrogen. What decisively drives the current interest into hydrogen is innovation and technological leadership on the one hand, which China can achieve through industrial clusters and economies of scale, and energy security on the other: reducing dependence on imported oil and gas, with rising importance of air pollution control- and decarbonization-related considerations. It remains to be seen whether China can avoid the shortcomings of its electric vehicles (EV) supporting policies as it aims to boost a hydrogen economy with Chinese characteristics. A simplified SWOT analysis presented in the report identifies the most important strength, weakness, opportunity and threat for hydrogen economy development in China: Strength - ability to significantly bring down unit manufacturing cost through industrial network clustering and economy of scale. Weakness - lag far behind advanced economies in key hydrogen-related technologies. Opportunity - enthusiasm on hydrogen economy by local governments against the backdrop of the Covid-19 pandemic. Threat - looming danger of global supply chain decoupling caused by an escalating US-China trade war. In order to move the hydrogen economy agenda forward, a preliminary 'to do list' for Chinese decision-makers in this field would include: A coordinated national mechanism should be established at the central government level to lay out principles for moving the hydrogen economy agenda forward in China. Comprehensive and transparent statistical reporting and accounting throughout the Chinese hydrogen value chain should be established. In the hydrogen production segment, renewable hydrogen should be prioritized for intensive Research and Development (R and D) and deployment in the near future, and greening China's existing hydrogen flow should be on the Chinese government's policy radar especially in the longer term. In the hydrogen storage and transport segment, national and local government should continuously direct subsidies towards hydrogen refueling stations, and also consider to encourage low concentration blending of hydrogen into China's natural gas network. In the hydrogen consumption segment, China should selectively focus on R and D and deployment of advanced hydrogen end-use technologies notably for cement and steel, ideally coupled with expansion of the horizon of national energy planning framework. Opening up the Chinese market to better integrate technology innovations in advanced economies and manufacturing-related competitive advantages of the Chinese economy, aiming to create a win-win situation between China and the international community.
[fr]L'annonce recente par le president Xi Jinping que la Chine vise la neutralite carbone en 2060 devra avoir un impact sur la strategie hydrogene poursuivie qui, pour l'instant, ne vise pas a aider la decarbonation de l'economie chinoise et repond a des imperatifs strategiques et industriels. Cette etude analyse les perspectives d'une economie chinoise de l'hydrogene et en dresse les principaux enjeux, forces et faiblesses.
