Energy transition reached a new level as environmentally friendly hydrogen was used to power the torch that lit the cauldron at the Beijing Winter Olympics opening ceremony.

It was the first time in Olympic history that a zero-emissions torch had been used for such an occasion.

As cauldrons used for previous Olympics consumed thousands of cubic meters of natural gas per hour, the use of hydrogen avoids substantial carbon emissions. Suppliers used to transport gas day and night to ensure sufficient fuel for the cauldron.

The hydrogen used to light the Winter Olympics flame in Beijing was supplied by China Petroleum and Chemical Corp, or Sinopec, the world's largest refiner by volume.

The company is to build a hydrogen processing unit at its Yanshan petrochemicals complex in the Chinese capital to ensure a sufficient supply of the clean fuel.

The nation has accelerated expansion of its hydrogen energy industry in recent years as it races toward a carbon neutral goal, with investment in the sector continuing to grow, according to experts.

A recently released report by global energy giant Royal Dutch Shell said the nation is making a concerted push to develop hydrogen technology and infrastructure, especially in industries such as heavy-duty road transportation, shipping and aviation, as well as steel and chemicals.

Industries that currently rely on fossil fuels, with few clean energy alternatives, need to transition to new lower-carbon energy sources, and hydrogen will play an important role in meeting such needs, the report said.

According to S&P Global Platts Analytics, the introduction of hydrogen to such industries is especially necessary, as China produces more than half the world's steel and cement, and use of the gas can significantly reduce related emissions.

For example, using hydrogen to manufacture steel can reduce total global carbon emissions by about 8 percent. The steel industry has come under increasing scrutiny due to its reliance on carbon-intensive fossil fuels.

Royal Dutch Shell suggests that heavy industry in China, which will remain a significant source of energy demand and consumption, should prioritize the replacement of coal with low-carbon hydrogen as its primary energy source.

The company said the introduction of hydrogen to such industry will place China in a leading position to pioneer new solutions to create momentum for change and to benefit from it. It will also give the nation an opportunity to become an exporter of low-carbon industrial products and technology, as well as low-carbon industrial expertise, the report added.

China is the world's largest user of pure hydrogen, consuming some 14.6 million metric tons annually, or 20 percent of global demand. According to S&P Global Platts, more than 95 percent of the hydrogen consumed is used for oil refining and ammonia synthesis.

Recognizing the importance of the gas as a low-carbon energy source and global growth industry, China's 14th Five-Year Plan (2021-25) names hydrogen as one of six industries of the future. The government is also expected to launch a comprehensive national hydrogen development plan soon. The plan will include a full ecosystem for a hydrogen economy, ranging from a strong manufacturing base for electrolyzers to the various downstream uses of "green" hydrogen.

Ivy Yin, energy transition analyst at S&P Global Platts, said that compared with overseas suppliers, China's hydrogen electrolyzers are already much cheaper for proton exchange membrane and alkaline technologies. Proton exchange membrane, or PEM, fuel cells are considered the most versatile type of such cells currently in production. They produce the most power for a given weight or volume of fuel cell.

Yin said, "China is expected to become a key global hydrogen equipment supplier by bringing down manufacturing costs, similar to the way in which it has led global solar panel production."

While penetrating new markets with low-carbon energy still requires huge investment in infrastructure-including hydrogen transportation, storage and delivery-as well as renewable electricity generation, these challenges are not unique to China, she said.

Along with renewables and nuclear energy, there is a need for carbon neutral hydrogen to continue increasing its share of China's energy mix to displace coal and gas, Yin added.

Cheaper option

According to strategic research provider BloombergNEF, China's aim for carbon emissions to peak by 2030 and to achieve carbon neutrality by 2060 will result in major emitters, including the power, transportation and other industries taking serious measures. This action will enable hydrogen to play a valuable role in "decarbonizing" long-haul trucks carrying heavy loads.

Mi Siyi, an analyst at BloombergNEF, said estimates show that these trucks could be cheaper to run by using hydrogen fuel cells, rather than diesel engines, by 2031.

The China Hydrogen Alliance, a government-supported industry group, predicts that the gas will make up at least 5 percent of the nation's energy mix by 2030, while the domestic hydrogen industry is expected to attract more than 300 billion yuan ($47.4 billion) this year.

Royal Dutch Shell is equally positive about the future for the clean fuel, believing that hydrogen use by 2060 will rise considerably from negligible levels today, mainly due to its application in industry and long-distance transportation.

The exponential increase in hydrogen demand will create opportunities for provinces with cheap renewable energy resources, the company said.

According to Yin, carbon neutral hydrogen uses excess renewable power supplies to produce green hydrogen when supply exceeds demand.

"Hydrogen can also be stored and easily transported across long distances, which is difficult for renewable energy due to the significant challenges associated with cross-regional power transmission," Yin said.

Chinese companies-public and private-are starting to draw up hydrogen development plans.

China Petroleum and Chemical Corp began constructing the world's largest green hydrogen project in Xinjiang Uygur autonomous region in November.

The plant is expected to produce 20,000 metric tons of green hydrogen annually after it starts operating next year, and is part of the company's $4.6 billion investment plan in the hydrogen sector through 2025. Sinopec also aims to boost its annual hydrogen production capacity to 500,000 tons by 2025.

Alan Hayes, an analyst at S&P Global Platts, said the Xinjiang project is an important test case that includes development of renewable power generation, new hydrogen production and new hydrogen storage. It can also replace high-carbon-based hydrogen with a low-carbon option for consumers.

"Not many other projects include the full hydrogen production and consumption chain, including development of renewable power generation, new hydrogen production and new hydrogen storage," he said.

The company has also vowed to build the world's largest hydrogen refueling network, with 1,000 stations by 2025, compared with just 100 nationwide by the end of last year. China currently boasts 200 hydrogen refueling stations and aims to have 300 by the end of this year.

In November, national energy giant State Power Investment Corp launched a demonstration project in Tibet autonomous region, focused on using hydrogen in preference to renewable-based power. Meanwhile, Baosteel, the country's largest steel producer, has also pledged to reach net-zero emissions by 2050, focusing on hydrogen-based steel production.

Plans drawn up

Cities nationwide are also preparing plans to tap the hydrogen sector, with more than 30 provinces and regions including this industry in their 14th Five-Year Plan, aiming to further take advantage of the cleaner fuel.

By 2025, the municipal authorities in Beijing aim to have 10,000 hydrogen fuel cell vehicles on the roads and 37 refueling stations for the gas, part of an ambitious plan to develop the hydrogen energy industry.

Shanghai is also planning to lead development of this industry by introducing 10,000 cars powered by hydrogen and more than 30 refueling stations by next year.

Shanxi province, a traditional area for coal mining, has pledged to become a national hub for the hydrogen industry, adopting development of the gas as part of its "energy revolution".

Yin, from BloombergNEF, said northern and northwestern provinces rich in renewables will benefit from the burgeoning hydrogen sector, as they have considerable wind and solar energy resources.

Multinationals are also planning to further tap the potential of hydrogen in China, confident in the nation's huge market potential. Companies such as Siemens, Thyssen-Krupp, Toyota, Ballard and Hyundai are drawing up hydrogen business plans in the country, eyeing the potential for the sector's development.

Hydrogen, currently produced mainly from natural gas, generates significant carbon emissions, known as "gray" hydrogen. "Blue" hydrogen has its carbon emissions captured and stored, or reused, while "green "hydrogen is generated by renewable energy sources without producing carbon emissions.

The nation's green hydrogen production capacity, based on renewable energy, is expected to reach 50,000 tons annually this year and is forecast to grow in years to come, according to the China Hydrogen Alliance.

It said the cost of harnessing solar and wind energy has continued to fall over the past 10 years, further boosting hydrogen's commercial viability.

According to Royal Dutch Shell, by 2060, up to 85 percent of the hydrogen used in heavy industry, agricultural machinery, heavy-duty road transportation, short-haul aviation, and shipping will be green hydrogen produced through electrolysis powered by renewable and nuclear energy.

However, Yin said China may take time to develop its role as an importer of green hydrogen and could lag behind markets such as Japan.

Royal Dutch Shell said infrastructure related to hydrogen will witness large increases in investment, particularly from the 2030s onward, as technologies and markets mature and are used to reduce emissions in sectors where it is hard to introduce electrification.

Annual investment to support the energy transition to net zero is estimated, on average, to be 1 percent higher than in recent years. However, in terms of energy supply, a significant reallocation of investment from fossil fuels to low-carbon electricity and low-carbon fuels such as hydrogen is required, the company said.

Directing some of this spending toward hydrogen-for example building hydrogen transportation and storage infrastructure-can stimulate demand in the short term and support climate-sustainable growth in the long term, it added.
