China’s Electrolysis Market: Would it Repeat Solar’s Success Story?

China’s electrolysis market has experienced explosive growth in the past six months, driven by the green hydrogen boom. By the end of August 2021, over 70 power-to-gas projects were under development in China, with regional governments announcing multiple initiatives. This rapid development is largely due to recent renewable policy changes, emphasizing the need for energy storage solutions, including power-to-gas technologies.

Comprehensive Insights into China’s Electrolysis Market

China is currently the world’s largest hydrogen production market, yet renewable-based hydrogen still holds a minor share. In 2020, total hydrogen production reached 25 million tons annually, with less than 3% derived from renewable sources like electrolysis. The demand for green hydrogen is surging, with production increasing by 25% year-on-year in the first half of 2021.

The market dynamics are shifting as various sectors, including solar, wind, and petrochemical industries, invest heavily in electrolysis technology. This influx of investment mirrors the trajectory seen in the photovoltaic sector around 2010, where Chinese manufacturers emerged as dominant players.

The Competitive Landscape

China’s electrolyzer market is characterized by a mix of established players and new entrants. Leading manufacturers like China Shipbuilding Industry Corp, Suzhou Jingli, and Shandong Saikesaisi dominate the market, holding around 60% of the share. However, the recent surge in interest has attracted various new players, including solar and wind companies, which are diversifying into electrolysis.

Local governments are also playing a crucial role by setting ambitious targets for PEM electrolyzer component manufacturing. This support is expected to accelerate the development of PEM technology, which is seen as the future of power-to-gas solutions.

Challenges and Opportunities

Despite the promising growth, challenges remain. The upstream gas market still faces uncertainties regarding transportation solutions and downstream applications. Additionally, the high cost of PEM electrolyzers, primarily due to the use of precious metals, poses a barrier to widespread adoption.

However, the increasing demand for green hydrogen and supportive government policies create significant opportunities for growth. The market is expected to evolve rapidly, with projections indicating that electrolysis could contribute significantly to hydrogen production by 2030.

Conclusion

China’s electrolysis market is on the brink of a transformation reminiscent of its solar industry success. With a robust domestic market, increasing investments, and supportive policies, the potential for growth is immense. As the market matures, it will be crucial to monitor the developments of both established and emerging players in this dynamic landscape.
