China’s dash for gas aims to cut back deadly winter smog

Millions of families in north of country prepare for first winter with cleaner – but more expensive – heating as authorities seek to cut back on use of coal

As freezing winds whip across northern China this winter, Yao Guanghui is happy he will have one less chore to do: feeding the coal furnace that has long heated his small house on the outskirts of Beijing.

Traipsing outside on freezing nights to haul coal for the two big burners in his kitchen was his least favourite household job.

But next month, the 60-year-old will turn on the heating with a flick of a switch on the gas-powered boiler that sits in a sooty alcove that once housed the furnaces.

“My face and nostrils would be covered with coal dust by the time I got into the kitchen,” he said on Thursday, recalling his efforts to carry coal into his two-room house during the long winter. “We hope this winter will be much cleaner and warmer.”

Yao and his family are among millions of people across northern China preparing for their first winter to be heated by gas – part of a government effort to wean the nation off dirty coal and improve the nation’s notoriously bad air.

The massive effort involves almost four million homes in 28 cities. The government is ploughing tens of billions of yuan into the project to install equipment, build thousands of kilometres of pipes and subsidise the higher costs of gas.

Beijing has been under increasing pressure to deal with chronic air pollution amid concerns about the damage it is causing to people’s health. Smog gets worse during the colder months when homes in the north of the country crank up heating that is overwhelmingly fired by coal.

The air quality index for the area around the village on Thursday morning was just four – a low level for anywhere in the world – but when smog shrouds the capital during the winter, it often soars into the hazardous hundreds.

Air pollution caused by coal-fired winter heating has slashed life expectancy in the north by more than three years compared with the south, according to a recent study by the University of Chicago.

Among other measures, China has pledged to impose tough industrial and traffic curbs this winter and is also in the process of shutting thousands of coal-fired industrial boilers.

For the global gas market, the potential impact of gasifying the world’s second-largest economy is enormous, with Russia and the United States poised to benefit from China’s growing need for foreign supplies.

Wood Mackenzie, a global energy firm, calculated that the effort will add 10 billion cubic metres of gas demand this winter. That is about 5 per cent of China’s consumption last year or the equivalent of Vietnam’s total annual use.

The project will also need heavy investment in infrastructure such as pipelines and storage tanks.

The pace and scale of the project over the past six months has been staggering, even for a place like China, where high-rise tower blocks and shopping centres go up with blistering speed.

A Reuters analysis of data released by the Ministry of Environmental Protection shows that two-thirds of the cities involved in the programme have surpassed the target set by the government to switch at least 50,000 homes to clean fuel by November.

That target would have seen 1.4 million homes switching.

However, two cities – Baoding and Langfang in Hebei – account for most of that total.

Beijing Gas, which is overseeing the plan in the capital, must lay over 3,000km of pipelines and build 400 service stations. It has connected 300,000 residents so far.

“Some of these projects are more complicated than we expected,” said an official from Beijing Gas who declined to be named as he is not authorised to speak to the media. He said the project involved building pipelines that went under the Great Wall and crossed environmentally sensitive areas.

On a recent visit to Yao’s village of Xiaozhangwan, a few kilometres from the outskirts of Beijing, old boilers were stacked along dusty narrow alleyways ready for scrapping.

Government engineers were rushing to install new radiators in 300 homes before the onset of winter.

In many houses, the radiators will replace systems that have been used for centuries in rural villages in northern China – burning coal to heat large beds where whole families gather during the winter.

Workmen were digging up the main street to lay the feeder pipeline that is connected to one of three pipelines that run for thousands of kilometres from Shaanxi province in northeastern China to the country’s northeast.

Some villagers are sceptical that gas will be as powerful as coal, and have insulated the walls of their homes and sealed windows to make them more efficient.

As they enter into the unknown, many residents also worry about higher bills. Gas prices are almost double those of coal.

The government will supply about 2,000 cubic meters of gas worth almost 5,000 yuan (US$750) at a discount to current residential gas prices, but Yao said he was unsure if that would see him through a particularly cold winter.

“I don’t know if that will be enough for heating and cooking for the family,” he said. “We will need to pay extra if we use more than that.”
