Development Strategy for Hydrogen Energy and Hydrogen Vehicles in Vietnam

Posted on by Haianh

On February 22, 2024, in Hanoi, the Ministry of Industry and Trade organized a conference (in-person and online with other localities) to implement Vietnam’s Hydrogen Energy Development Strategy until 2030, with a vision to 2050 (Hydrogen Energy Strategy), which was approved by the Prime Minister in Decision No. 165/QD-TTg on February 7, 2024.

The strategy sets a general goal to develop a hydrogen energy ecosystem that includes production, storage, transportation, distribution, and use of hydrogen with synchronized, modern infrastructure, based on renewable energy, contributing to energy security, achieving the national goals on climate change, green growth, and net-zero emissions by 2050.

The strategy also aims to deploy advanced technology in the production of green hydrogen energy and other hydrogen energy production technologies using CCS/CCUS from various fuel sources in Vietnam by 2030. It is expected that the production capacity of hydrogen from renewable energy processes and other processes with carbon capture will reach about 100,000 – 500,000 tons per year by 2030.

Thus, if the goal of building infrastructure for the production, use, storage, transportation, and distribution of hydrogen energy becomes a reality, it would be entirely feasible for automobile manufacturers to introduce hydrogen-powered vehicles to Vietnam. This is because they would then benefit from government incentives and have the necessary conditions to operate. Fuel for hydrogen vehicles would also not be as expensive as it is now.

Keith Wipke, the program director for hydrogen and fuel cell technology testing at the U.S. National Renewable Energy Laboratory, predicts: “In just a few decades, hydrogen stations and hydrogen vehicles will have a bright future everywhere, not just in the United States.”

BIGNANOTECH is looking for partners to co-develop this highly potential field.

How to Utilize Spilled and Leaked Oil?

Posted on by Haianh

Lubricating oil, crude oil, and oil-based fluids have long been the primary source of fuel for most industrial activities and daily life. Machinery and equipment using oil are present in almost all factories, plants, manufacturing workshops, repair shops, warehouses, etc. Therefore, industrial hygiene and the treatment of spilled and leaked oil during operations and production are currently one of the issues of concern.

The amount of spilled oil due to accidents, oil leaks, and waste oil from factories and plants is extremely large every year. If not properly handled, it can cause environmental pollution, affect the health of workers, and result in certain waste for businesses.

Common methods for collecting, cleaning oil, fuel, and industrial fluids

Currently, one of the most optimal methods for industrial cleaning and handling oil spill incidents is to use high-tech absorbent products such as:

These products are manufactured using exclusive nano-fiber technology from Japan, so they can absorb oil quickly and absorb more oil than traditional cleaning utensils such as mop cloths or rags. This helps businesses save cleaning costs and minimize storage space.

Moreover, specialized oil absorbent products only absorb oil and oil-based fluids, not water, so they are often used to clean oil stains, leaks on machinery and equipment, factory floor surfaces. They are also used to control and treat oil spill incidents on rivers, lakes, seas, fields, etc.

They also have anti-static, non-flammable, non-combustible properties, meeting fire and explosion prevention standards and safety in storage and use.

Utilizing spilled oil

After using these products to absorb and collect spilled oil, the next important step is how to avoid wasting that oil. With high-tech specialized products such as oil absorbent pads, oil absorbent pillows, we can recover much of the absorbed oil by squeezing or using centrifuges. This oil can then be further filtered using oil filter fabric or oil filter machines and reused.

For wastewater containing non-reusable oil, oil filter fabric can be used to filter out all waste, oil residues, and oil sludge before discharging into the environment or undergoing other waste treatment processes.

In these ways, businesses can save a lot of fuel costs and waste treatment costs, while minimizing the risk of oil leakage through waste routes causing environmental pollution.

For effective oil spill collection and treatment, businesses need to prepare contingency plans and spill response procedures as well as standard hygiene procedures for their employees. Above all, they need to research high-tech specialized products and prepare backups to proactively handle any incidents that may occur, ensuring the most efficient operation and economic efficiency for their businesses.
