Report on the Fukuoka Osmotic Power Plant and its Contribution to Sustainable Development Goals

Introduction and Overview

• Japan has inaugurated its first osmotic power facility in the city of Fukuoka. This development represents a significant advancement in renewable energy technology, directly supporting Sustainable Development Goal 7 (Affordable and Clean Energy).
• The plant is projected to generate approximately 880,000 kilowatt-hours of electricity annually.
• This output is designated to help power a local desalination plant, an initiative that aligns with SDG 6 (Clean Water and Sanitation) by enhancing water security for the city and surrounding areas.
• The energy generated is also equivalent to the annual consumption of approximately 220 Japanese households.

Technological Principles and Sustainable Advantages

• The facility operates on the principle of osmosis, harnessing the energy created when freshwater and saltwater are separated by a semipermeable membrane.
• Water flows from the freshwater side to the pressurized seawater side, increasing the volume and pressure, which is then used to drive a turbine and generate electricity.
• A key advantage of this technology is its ability to provide a constant and reliable power source, operating 24/7 regardless of weather conditions. This stability is a crucial element for achieving the targets of SDG 7.
• The use of treated wastewater as the freshwater source further contributes to SDG 6 by integrating water reuse into the energy production cycle.

Global Context and Innovation

• The Fukuoka plant is the second commercial osmotic power facility in the world, following the first plant established in Denmark in 2023.
• This expansion of osmotic power technology demonstrates progress toward SDG 9 (Industry, Innovation, and Infrastructure), showcasing the development of resilient and sustainable infrastructure.
• Pilot-scale demonstrations and prototypes have been established in other locations, indicating growing global interest. These include:

1. Norway
2. South Korea
3. Spain
4. Qatar
5. Australia

Challenges and Technological Advancements

• Scaling the technology presents challenges, primarily related to overcoming energy losses associated with pumping water and frictional loss across membranes.
• Advances in membrane and pump technology are progressively reducing these inefficiencies, making the process more viable.
• The Fukuoka plant employs an innovative strategy by using concentrated seawater (brine), a byproduct of the desalination process. This increases the salinity difference, thereby maximizing the potential energy generation and creating a synergistic system that supports SDG 11 (Sustainable Cities and Communities).

Future Outlook and Contribution to Global Goals

• The successful operation of the Fukuoka plant provides critical proof-of-concept for the large-scale application of osmotic power.
• This technology has significant potential to contribute to global climate targets under SDG 13 (Climate Action) by diversifying the renewable energy portfolio with a consistent, non-intermittent power source.
• Future implementation is feasible in numerous coastal locations worldwide where freshwater or treated wastewater sources are available near saltwater.
• Increased investment and government support could accelerate the adoption of this technology, assisting nations in meeting their sustainable development commitments.

Analysis of the Article in Relation to Sustainable Development Goals

1. Which SDGs are addressed or connected to the issues highlighted in the article?

It highlights the challenges of scaling up the technology and the importance of advances in membrane and pump technology.
• SDG 11: Sustainable Cities and Communities – The power plant is located in the city of Fukuoka and contributes to its sustainability by providing clean energy and supporting the supply of fresh water, making the urban infrastructure more resilient and environmentally friendly.
• SDG 13: Climate Action – By generating electricity without burning fossil fuels, osmotic power represents a technology that can help combat climate change and its impacts. It is a form of renewable energy that contributes to reducing greenhouse gas emissions.

2. What specific targets under those SDGs can be identified based on the article’s content?

1. SDG 6: Clean Water and Sanitation

   • Target 6.1: By 2030, achieve universal and equitable access to safe and affordable drinking water for all. The article connects to this by describing how the power plant supports a desalination facility that “supplies fresh water to the city and neighbouring areas.”
   • Target 6.4: By 2030, substantially increase water-use efficiency across all sectors and ensure sustainable withdrawals and supply of freshwater to address water scarcity. The plant contributes to a sustainable supply of freshwater through desalination, powered by a clean energy source.
   • Target 6.a: By 2030, expand international cooperation and capacity-building support to developing countries in water- and sanitation-related activities and programmes. The article mentions prototypes and expertise being shared internationally, with examples in Japan, Denmark, Norway, South Korea, Spain, and Qatar.

2. SDG 7: Affordable and Clean Energy

   • Target 7.2: By 2030, increase substantially the share of renewable energy in the global energy mix. The osmotic power plant is a direct example of increasing the share of renewable energy, as it generates electricity from a non-fossil fuel source. The article emphasizes its advantage as a steady, 24/7 renewable source.
   • Target 7.a: By 2030, enhance international cooperation to facilitate access to clean energy research and technology, including renewable energy… and promote investment in energy infrastructure and clean energy technology. The article describes this as an “emerging technology” with pilot demonstrations and prototypes in multiple countries (Japan, Denmark, Norway, South Korea, Spain, Qatar, Australia), indicating international research and development efforts.

3. SDG 9: Industry, Innovation, and Infrastructure

   • Target 9.4: By 2030, upgrade infrastructure and retrofit industries to make them sustainable, with increased resource-use efficiency and greater adoption of clean and environmentally sound technologies and industrial processes. The Fukuoka plant is a new piece of infrastructure built on a clean and environmentally sound technology.
   • Target 9.5: Enhance scientific research, upgrade the technological capabilities of industrial sectors in all countries… encouraging innovation. The article is centered on a technological innovation, discussing its development, challenges (“advances in membrane and pump technology”), and potential for “large-scale energy production.”

3. Are there any indicators mentioned or implied in the article that can be used to measure progress towards the identified targets?

1. SDG 7: Affordable and Clean Energy

   • Indicator 7.2.1: Renewable energy share in the total final energy consumption. The article provides a specific metric for the plant’s output: “it is expected to generate about 880,000 kilowatt hours of electricity each year.” This figure is a direct measure of the amount of renewable energy being added to the grid.

2. SDG 9: Industry, Innovation, and Infrastructure

   • Implied Indicator: Number of new, clean technology infrastructures implemented. The article explicitly states this is the “first osmotic power plant” in Japan and the “second power plant of its type in the world.” The count of such facilities serves as a clear indicator of the adoption of this innovative technology.

3. SDG 6: Clean Water and Sanitation

   • Implied Indicator: Population served by sustainably managed drinking water services. While not providing a specific number, the article indicates that the plant helps power a desalination facility that “supplies fresh water to the city and neighbouring areas,” which implies a measurable population benefits from this sustainable water source.
