Chinese scientists have created starch, a type of complex carbohydrate found in plants, using carbon dioxide, hydrogen and electricity, according to a study published in the journal Science on Friday.

Experts said if such technique can be scaled-up to the level of industrialization, it may revolutionize how this key nutrient and industrial ingredient is made, since it does not require farming and processing large quantity of starchy crops such as sweet potato and maize, thus saving more water, fertilizer, and arable land.

It may also be used to recycle carbon dioxide, a common industrial waste and a greenhouse gas, into a consumable product. This will help reduce carbon emission and combat climate change, especially if the electricity used is from renewable sources like solar and wind.

In space exploration, it may provide a sustainable food source for astronauts as they travel long distances in space and try to colonize other planets where growing food is unviable. Future space travelers may simply turn the carbon dioxide they breathe out into food they eat.

Ma Yanhe, the director of the Tianjin Institute of Industrial Biotechnology of the Chinese Academy of Sciences, said starch and other complex carbs make up of 60 to 80 percent of the human diet.

"Our breakthrough demonstrates that synthesizing complex compound like starch is achievable in a lab, and there are many industries that can benefit from this technology," he said.

Starches are widely used in sugar production, food and beverage processing, printing, drug-making, textile, animal forage and dozens of other industries, according to Bric International Group, a global agricultural data firm. This prompted the manufacturing of corn starch and its derivatives into an 80 billion yuan ($12.4 billion) industry in China.

Plants create carbohydrates like starch through photosynthesis, which is an extremely complex and inefficient process, said Ma, adding it would take a plant about 60 steps of metabolic reactions to turn carbon dioxide, water and sunlight into starch.

Cai Tao, one of the first authors of the study, said for six years, his team has been focusing on a single project: how to make starch like plants, but do it much faster.

Creating carbohydrate via more effective means is so important for sustainability on Earth and future space exploration that NASA listed converting carbon dioxide to glucose, a simple sugar, as one of its centennial challenges in 2018. Starch is made of a much more complex chain of glucose molecules.

Cai said their method involves first converting carbon dioxide and hydrogen gas into methanol, which is molecule that contain a single carbon atom.

Scientists then piece these single-carbon molecules like a puzzle into bigger and more complex molecules via enzymatic processes.

With the help of supercomputing, Chinese scientists have streamlined the natural starch making process from about 60 into 11 steps, with the final product being starch. Cai said the lab-made starch is chemically identical to starch in nature, whose solution can turn blue with iodine.ext

Behind multiple power rationing: dual control regulation of energy gap is the main reason, which will force the reform of energy structure

Our reporter Zhang Zhi reports from Beijing



For two or three days in a row, Yichun, Heilongjiang Province has experienced power and water outages.
According to the reporter, since September 23, in order to ensure the safe and stable operation of the power grid, according to the instructions of the Northeast power grid, some areas of the three northeastern provinces began to take power restriction measures, and some areas had to limit power during peak hours. At the same time, the power supply gap is still, and the tense situation of power consumption in the three eastern provinces may continue for some time in the future.
Not just the northeast. It is understood that at present, with the upgrading of the dual control policy of energy consumption in many places, 16 provinces have issued power restriction measures with varying degrees of strength - Sichuan, with less strength, requiring "suspension of unnecessary production, lighting and office load"; Ningxia requires "high energy consuming enterprises to stop and limit production for one month". Jiangsu, Guangdong, Zhejiang and other major chemical industry provinces have made heavy attacks, and thousands of enterprises have taken measures such as "opening two, stopping five" and "limiting production by 90%.
"The power restriction policy is directly related to China's power demand, which also shows the necessity of China's economic transformation," said Lin Boqiang, President of China Energy Policy Research Institute of Xiamen University.
Multi place power limitation
With the rapid economic recovery, this year's power shortage has also come ahead of schedule. Guangdong, a big manufacturing province, was the first to lack electricity.
As early as may this year, the load of Guangdong power grid hit a record high. Data show that in the first half of this year, the consumption of the whole society in Guangdong increased by 22.89% year-on-year, with an average growth rate of 9.7% in the two years.
This is the first time that there is a gap in power load in Guangdong after the global financial crisis, so a large-scale power rationing has to be started.
Since September 16, Guangdong has implemented the "two on and five off" power consumption scheme. From Sunday to Thursday, it should realize staggered peak rest, and only retain less than 15% of the security power load. Affected by this, some enterprises have to adjust the resumption time to 24:00-8:00 in the morning to ensure normal production.
On September 22, the person in charge of a key manufacturing enterprise in the Pearl River Delta received a notice on "orderly power consumption rotation", which said that due to the rapid growth of power consumption and weather reasons, the enterprise should take the initiative to cut off the peak power at 8 to 24 o'clock in the next two days. If it does not perform, it will be forced to cut off the power for 48 hours. It is understood that this is the first time that the local government has shut down power for key enterprises. Affected by this, some key enterprises announced that they would stop production and even give employees a National Day holiday in advance.
But power rationing in Guangdong is only a microcosm.
In fact, power rationing is not only a problem of energy shortage, but also affected by the national dual control policy and environmental protection.
It is still 8 years away from China's carbon peak target in 2030, but China's energy consumption control still needs to be improved. The data show that in 2020, the energy consumption of 10000 yuan GDP decreased by only 0.1% year-on-year, and the total energy consumption increased by 2.2%.
In the first half of this year, the national development and Reform Commission issued the barometer for the completion of the dual control target of energy consumption in all regions in the first half of 2021. Among them, 12 regions such as Qinghai, Ningxia, Guangxi, Guangdong, Fujian, Xinjiang, Yunnan, Shaanxi, Jiangsu, Zhejiang, Anhui and Sichuan showed a severe trend in terms of energy consumption reduction and total energy consumption, which means that more than half of the provinces in the first half of this year The goal of "dual control" was not completed.
"The main reason why energy consumption is rising instead of decreasing is that key energy consuming enterprises use energy disorderly and illegally," said Qi Yusong, deputy director of Jiangsu Provincial Department of industry and information technology.
With the approaching of the year-end examination, if the "named" areas want to reverse the situation, they must take certain measures to improve the energy consumption as soon as possible.
Since September 15, starting from Nantong, Jiangsu has implemented power rationing in some areas, and adopted "two starts, two stops and five stops" and "90% production restriction" for local enterprises During this period, industrial power consumption was limited, unified maintenance for half a month, office air conditioning was stopped, street lamp control was halved, and some enterprises directly issued a 17 day holiday notice; in Taizhou, enterprises were required to stop work from the 16th to the end of the month.
In Guangxi, the local government implements the schemes of "stopping 5-on-2", "stopping 2-on-5" and "stopping 3-on-4", and limits the production of high energy consuming enterprises such as electrolytic aluminum, alumina, steel and cement; Yunnan requires that the monthly average output of industrial silicon enterprises from September to December shall not be higher than 10% of the output in August (i.e. 90% reduction); the monthly average output of yellow phosphorus production line from September to December shall not exceed 10% of the output in August 2021 (i.e. cut production by 90%).
Shaanxi requires that the newly built "two high" projects shall not be put into production from September to December. The new and put into operation "two high" projects this year shall limit the production by 60% based on the output of the previous month. Other "two high" enterprises shall implement measures such as reducing the operation load of the production line, shutting down the submerged arc furnace and limiting the production to ensure a 50% reduction in production in September.
Up to now, all localities are still introducing power restriction measures.
Forced transformation
Different from the staggered peak power consumption policy during the peak power consumption in summer in previous years, the "dual control of energy consumption" has become a factor repeatedly mentioned in the adoption of power restriction measures.
"In the first half of this year, our economy recovered well, but local energy consumption grew rapidly and increased greatly. In particular, the growth rate of electricity consumption in the eight high energy consuming industries reached more than 20%. The excessive growth of energy consumption and the change of energy consumption structure brought very severe challenges to the situation of energy and resource security and dual control of energy consumption in the province. In order to curb the excessive growth of energy consumption in high energy consuming industries, some local governments We should double control the progress of energy consumption, organize and carry out measures such as energy budget management, orderly power consumption and peak staggering production of high energy consuming enterprises, which is a corrective measure for the original neglect of energy conservation and emission reduction, "said the person in charge of Zhejiang Provincial Energy Bureau.
According to the outline of the 14th five year plan, "energy consumption per unit of GDP and carbon dioxide emissions will be reduced by 13.5% and 18% respectively" has become one of the main binding indicators of economic and social development. The government work report at the beginning of this year proposed that the goal of reducing energy consumption per unit of GDP in 2021 is about 3%.
Time is tight and the task is heavy. In the face of the assessment of dual control objectives of energy consumption and the policy document of multiple underground energy consumption, we should "adhere to the combination of government regulation and market orientation, give full play to the decisive role of the market in the allocation of resources" and impose restrictions on enterprises with high pollution and high energy consumption. On September 16, the national development and Reform Commission issued the plan for improving the dual control of energy consumption intensity and total amount It is also proposed that we should adhere to the combination of incentive and restraint, strictly carry out dual control assessment of energy consumption, strengthen incentive in areas with remarkable work results, and seriously hold accountable in areas with ineffective goal completion, so as to form an effective incentive and restraint mechanism.
In the view of people in the industry, the goal of "dual control of energy consumption" is to promote clean, low-carbon, safe and efficient utilization of energy, and force the adjustment and upgrading of industrial structure and energy structure. At present, "dual control of energy consumption" It will become an important driving force for China's low-carbon development. Therefore, pan Helin, executive director of the Digital Economy Research Institute of Central South University of economics and law, suggested that we should make good use of the new energy power sector, especially the photovoltaic + energy storage integration mode as an energy supplement, make use of peak valley power for power allocation, and industrial enterprises will use photovoltaic to achieve self-sufficiency in some energy consumption. On the other hand On the one hand, high-energy consuming enterprises are facing transformation pressure and need to reduce energy consumption through energy management and energy source structure optimization.
