2023年全球清洁氢市场规模达17亿美元。展望未来， IMARC Group预计到2032年市场规模将达到56亿美元，2024-2032年复合年增长率（CAGR）为13.7%。

清洁氢是指透过永续程序获得的氢，有助于降低碳排放量。清洁氢气可以透过再生能源（绿氢）供电的电解或透过蒸汽甲烷重整结合碳捕获和储存（CCS）（蓝氢）来生产。清洁氢的主要优点是其能够生产和消耗清洁燃料而不释放直接温室气体（GHG）或污染物排放，并且具有广泛的清洁生产途径。此外，以生物质或沼气和碳管理技术生产的氢气将导致负排放，从而消除大气中二氧化碳（CO2）的微量排放。清洁氢在炼油化工、发电与储能、汽车、重型机械等​​领域有广泛的应用。

清洁氢市场趋势：

该市场主要受到全球碳替代燃料需求不断增长的推动。这可以归因于人们对各种最终用途行业使用化石燃料所产生的碳排放量增加的日益关注。此外，一些国家政府机构采取的支持氢经济的有利政策和措施也为市场提供了动力。燃料电池汽车（FCV）充电对清洁氢气的需求不断增加，以抑制车辆排放并最大限度地减少空气污染，这也为清洁​​氢气在交通应用中创造了利润丰厚的机会。燃料价格的持续上涨以及对化石燃料枯竭的担忧加剧进一步推动了市场。除此之外，大众对全球暖化和气候变迁的认识不断提高，正在创造积极的市场前景。推动市场发展的其他一些因素包括快速工业化、可支配收入水准的提高以及主要参与者进行的广泛研发（R＆D）活动。

The global clean hydrogen market size reached US$ 1.7 Billion in 2023. Looking forward, IMARC Group expects the market to reach US$ 5.6 Billion by 2032, exhibiting a growth rate (CAGR) of 13.7% during 2024-2032.

Clean hydrogen refers to hydrogen that is obtained through sustainable procedures and is instrumental in reducing the level of carbon emissions. Clean hydrogen can be produced through electrolysis powered by renewable sources (green hydrogen) or through steam methane reforming combined with carbon capture and storage (CCS) (blue hydrogen). The main advantage of clean hydrogen is its ability to produce and consume clean fuels without releasing direct greenhouse gas (GHG) or pollutants emissions, along with the availability of a wide range of clean production pathways. Additionally, hydrogen produced with biomass or biogas and carbon management technologies would result in negative emissions, thus removing traces of carbon dioxide (CO2) emissions from the atmosphere. Clean hydrogen finds extensive applications in the refining and chemicals industries, power generation and energy storage, automobile, and heavy machinery.

Clean Hydrogen Market Trends:

The market is majorly driven by the escalating demand for carbon alternative fuels across the globe. This can be attributed to the growing environmental concerns regarding increasing carbon emissions from fossil fuel usage contributed from a wide range of end-use industries. Moreover, favorable policies and initiatives undertaken by government bodies of several countries supporting hydrogen economy are providing an impetus to the market. The augmenting demand for clean hydrogen for charging fuel cell vehicles (FCV) to curb emissions from vehicles and minimize air pollution is also creating lucrative opportunities for clean hydrogen in transportation applications. The market is further propelled by a continual increase in fuel prices, along with increasing concerns regarding fossil fuel depletion. Apart from this, the rising awareness regarding global warming and climate change among the masses is creating a positive market outlook. Some of the other factors contributing to the market include rapid industrialization, inflating disposable income levels, and extensive research and development (R&D) activities conducted by key players.
