Cultivate algae manufacturing biofuels to achieve net zero emissions
2023/7/12
According to the Japanese Economic News recently, April this April this year, Chitose Laboratory, headquartered in Kawasaki, Japan, set up the world's largest algae culture facility in Malaysia to use carbon dioxide to produce biofuels. The company's goal is to control its cost at the level of competition with fossil fuel when cultivating algae manufacturing biofuels.
Chitose Laboratory companies are not the only companies that have high hopes for cultivating algae manufacturing biofuels. They are the same as those with Taoism and companies from Germany. They all hope to cultivate algae to make fuels and achieve net zero emissions. Of course, at present, the cultivation of algae "transforming" biofuels is also facing problems such as high cost and technological innovation.
Biofuels attract attention
In recent years, biofuels have received great attention, because they are considered carbon neutral, helping to replace fossil fuels and alleviate global warming. The algae is very potential for biomass fuels for raw materials, but large -scale algae production still faces challenges such as carbon supply, water supply and land demand.
According to reports, the algae culture facilities established by Chitose Laboratory are located in the thermal power stations near the capital of Saramo, Malaysia. In the area of about 4.6 hectares, the research team is densely placed with transparent bags equipped with a culture medium to cultivate light green algae. The intense sunlight unique to tropical can stimulate algae activities.
The codonic algae is called "clothing algae", which can absorb carbon dioxide and metabolize with the help of photosynthesis. During this process, lipids are generated. Researchers can extract fatty acids (raw materials produced by oil) from lipids, and then refine them. The bio -fuel obtained can be used for aircraft and cars.
It is reported that the carbon dioxide used to cultivate algae comes from the gas discharged from the thermal power station. For the staff to cultivate algae for about 3 days, they can extract lipids and proteins. Based on dry weight, 350 tons of algae can be produced each year, and up to 8 tons of sustainable aviation fuel (SAF) can be produced.
Many companies have high hopes for algae
The projects led by Chitose Laboratory are named Matsuri, and companies such as Mitsui Chemistry, Eneos and Koshengtang participated in the project.
In addition, Germany Fasto Co., Ltd. also launched a "bionic cell factory", which is a device that cultivates algae in transparent tubes that rarely contact external air. Through the "Bionic Blaom" project, Festo showed its first biore reactor for algae automation culture at the 2022 Hannover Industrial Expo.
At the Hanover Industrial Expo in 2023, the company demonstrated the next step on the road of biological transformation: bionic cell factory. The bionic cell factory includes an overall biological process: from continuous monitoring and analysis to optimize the cultivation of algae cultivation to harvest, and then further processing and refining of various components. The products obtained can be used in the chemical, food or pharmaceutical industry. Contrary to the chemistry process, the entire operation does not require high temperature and high pressure, nor involves toxins.
According to reports, the device can absorb carbon dioxide from the air, concentrate it to the algae, and automatically manage the temperature to provide nutrients such as phosphorus and nitrogen. It also monitors the size and quantity of algae, master growth, and use biological enzymes to refine lipids later.
Reducing costs is the top priority
Although the cultivation of algae manufacturing bio -fuel has a broad prospect, its cost is relatively high compared to traditional fossil fuels and other biofuels.
First of all, the cultivation of algae needs to carefully control the environmental conditions, such as light, temperature and nutrients, which may have technical challenges and consume a lot of energy. The "Japan Economic News" website pointed out in the report that the traditional approach is to cultivate algae in large outdoor large pools, but this method is easy to mix with mixed bacteria, and the cost of building large pools is relatively high.
In view of this, Chitose Laboratory companies use low -cost polyethylene bags, which can easily carry out large -scale production. The company's goal is that the construction of construction with a scale of 2,000 hectares since 2027 is about 400 times the existing scale. The company said that with the expansion of production scale, the cost of using algae manufacturing biofuels will be reduced to about $ 3 per liter in the future.
Some technology consulting companies have pointed out that if they are about $ 3 per liter, algae -made biofuels can compete with other fuels including fossil fuels. It is reported that the Japanese government put forward the goal of dropping production costs to about 100 yen (about $ 0.7) in 2030.
In addition, the dryness of algae to separate lipids also requires a lot of time and labor, which is also the main reason for high costs. Dacheng Construction Co., Ltd. and Saitama University have developed algae that can excrete liposcope in vitro, which can save the dry and lipid separation process that consumes a lot of energy. This method is not only simpler, but also algae can continue to grow.
Technological innovation is indispensable
The industry agreed that in order to further reduce costs, it is necessary to carry out technological innovation.
Researchers have been improving the algae cultivation system, such as open ponds, closed photogenic reactors, etc., to optimize the growth conditions of algae and improve productivity. Advanced monitoring and control systems, including automation and artificial intelligence, have also been integrated into the algae culture system to optimize nutrient absorption, light and other growth parameters.
Researchers have also been developing more advanced harvesting and extraction methods, such as flocculation, centrifugal and solvents, to improve lipid recovery efficiency while reducing energy consumption and production costs. In addition, it is also exciting to cultivate algae using places where deserts and other crops cannot grow.
