Oil Pollution in the Downstream of Rivers: Unnoticed Potential Threats

Posted on by Haianh

Major rivers are not just a source of life and economic sustenance for people, but also a rich energy source that we need to safeguard. Currently, hydroelectricity is often considered a clean and efficient power source. However, the operation of hydroelectric plants still harbors an unnoticed risk: the threat of oil pollution in the downstream of rivers. This is an issue that is becoming increasingly severe and requires deeper awareness.

When a hydroelectric plant operates, one of the greatest risks is the leakage of oil from oil transport vehicles or from oil storage tanks, as well as discharge ponds within the plant. Although wastewater undergoes strict treatment and control measures before being discharged into the environment, accidents can still occur unexpectedly and cannot be accurately predicted. Especially when machine oil contaminates wastewater, it can leak into the river, causing serious impacts on the environment and the livelihoods of communities downstream.

One of the major consequences of oil pollution is the negative impact on river ecosystems. Oil can harm aquatic flora and fauna, leading to a significant decline in underwater species. This not only affects the ecological balance but also jeopardizes the food supply and livelihoods of communities along the river.

Moreover, oil pollution can also pose serious health issues for humans. Toxic compounds in oil can accumulate in fish and other aquatic organisms – a food source consumed daily by humans. If not promptly and effectively addressed, oil pollution can have long-term health effects on communities.

Not only does oil pollution entail unpredictable consequences, but it can also cause prolonged and challenging impacts to fully rectify. To minimize the risk of oil pollution in the downstream of rivers from hydroelectric plants, stringent environmental protection and safety measures need to be implemented. Additionally, there should be enhanced monitoring and strict compliance with regulations regarding oil usage and wastewater treatment containing oil.

Furthermore, plants need to have thorough preparedness and contingency plans in place to promptly address any accidents. The application of effective oil treatment technologies plays a crucial role in minimizing pollution risks and enhancing industrial hygiene efficiency at plants and downstream river areas.

Some suitable products for spill response, industrial hygiene, and oil pollution prevention at plants include:

In summary, oil pollution in the downstream of rivers from hydroelectric plants is not just a hidden issue but also a significant threat to the environment and human health. Addressing and rectifying this issue requires collaborative efforts from all stakeholders, from government and businesses to local communities, to protect and preserve this precious environmental resource for future generations and ourselves.

Production of Green Hydrogen in Vietnam: Demand, Potential, and Challenges

Posted on by Haianh

Alongside renewable energy development solutions, the utilization of energy-saving, efficient, and low-carbon emission electricity sources such as green hydrogen and its derivatives has garnered significant global attention and high expectations. This is a crucial solution in the energy transition journey as well as for reducing emissions in various industrial sectors.

Green hydrogen is a clean fuel produced from water electrolysis technology and renewable energy, contributing to emission reduction goals and economic development. According to experts, green hydrogen is expected to be used in industries already utilizing gray or brown hydrogen fuels, including oil and gas, chemicals, steel production, and particularly in transportation.

While the production and use of green hydrogen are still emerging fields in Vietnam, this topic is increasingly attracting market attention.

1. Demand for hydrogen usage in Vietnam

In Vietnam, hydrogen is currently a feedstock for production in several industrial sectors, with the most significant usage in oil refining, chemicals, fertilizer production, and steelmaking. In 2020, according to assessments by the Institute of Petroleum Research, fertilizer production plants consumed about 316,000 tons of hydrogen, while the Dung Quat and Nghi Son oil refineries consumed 39,000 tons and 139,000 tons per year, respectively. Currently, many countries worldwide, such as Japan, South Korea, and China, have announced specific green hydrogen development strategies in the medium and long term as a solution to reduce emissions and mitigate global warming impacts.

According to research results from the Energy Institute (calculating green hydrogen demand), the demand for green hydrogen for developing various economic sectors in Vietnam is significant. However, the current production and application technology of green hydrogen are not yet perfected and have plenty of room for development. Therefore, the demand for green hydrogen will change depending on the development of production technology, storage infrastructure, usage, and distribution.

2. Potential for hydrogen development in Vietnam

Vietnam has early recognition of the profound impacts of climate change, leading to efforts through commitments to achieve net-zero emissions by 2050 at COP26 and continuously increasing solar and wind energy capacities. Additionally, it has announced fair energy transition partnerships worth $15.5 billion with an international partner alliance (JETP) and representatives from several other countries.

Industries related to hydrogen in Vietnam currently and with strong potential for future development include oil refining, fertilizer production, electricity generation, transportation, steel, cement, etc.

Clean hydrogen resources: wind power (onshore, offshore), solar energy.

The government and state have specific goals, roadmaps, and policies for hydrogen development, such as Resolution NQ-55/TW (2020), NDC (2020), Decision 876/QD-TTg (2022), Decision 888/QD-TTg (2022), Decision 896/QD-TTg (2022), Decision No. 28/QD-TTg (2022), Power Development Plan 8 (PDP8), NEP, etc.

3. Challenges in green hydrogen production

Although there is significant potential for development, achieving desired production levels quickly and replacing current fossil fuel sources is not an easy path.

Firstly, infrastructure: To achieve economic efficiency, Vietnam will need to build large-scale electrolysis plants and other infrastructure to serve the production, storage, distribution, and use of green hydrogen (logistics platforms, ports, vessels, pipelines, etc.).

Secondly, substantial investment, high costs: Production of hydrogen, in general, and green hydrogen, in particular, requires more energy than other fuel types, making it much more expensive. Analysts estimate that green hydrogen prices need to halve to compete with gasoline and diesel.

Thirdly, environmental risks related to residuals: Coastal countries operate based on desalination plants, but they pose many environmental risks related to residuals during production.

Fourthly, specific transportation requirements: According to IRENA, by 2050, 50% of green hydrogen transactions will be transported via pipelines, where part of it currently used to transport natural gas will need to be converted for functionality. At distances exceeding 3,000 km, green hydrogen can be transported in liquefied form, requiring much lower temperatures than natural gas (-250°C compared to -160°C) or in ammonia form.

Fifthly, safety assurance: This is also a concern because hydrogen is a volatile and flammable element. Therefore, stringent safety measures are necessary to prevent leaks and explosions.
