Project Summary
Elevator Pitch

Concise Summary: Help us pitch this solution! Provide an explanation within 3-4 short sentences.

The mixing of freshwater and seawater where rivers flows into the salty ocean releases large amounts of energy that can be used for power production. The pressure retarded osmosis (PRO) process will operate with filtered fresh water pumped into modules containing membrane.

WHAT IF - Inspiration: Write one sentence that describes a way that your project dares to ask, "WHAT IF?"

seawater could generate power in most ecological way?
About Project

Problem: What problem is this project trying to address?

The most prominent challenges are to produce an efficient membrane with high flux and high pressure. This membrane must be designed and up-scaled to an industrial production level, and with membrane life time verification. Further plans will include the construction and verification of prototype systems. Later this will lead to full scale demonstration plants and introduction to the energy market.

Solution: What is the proposed solution? Please be specific!

The advantages of a new renewable energy source. Capital cost for an osmotic power plant is relatively high even compared to wind power. However, the osmotic power plant will be designed to operate at full capacity more than 7000 hours a year yielding a power generation capacity which is very high for each MW installed. This reduces the PRO energy cost to an attractive level. Being a renewable energy source with a high environmental performance of the osmotic power technology will be subject to subsidy programmes and green certificate schemes similar to those seen for wind power and solar power today. It produces no sound .The main advantage is that it produces 0% carbon dioxide, hence keeping the environment pollution free.
Impact: How does it Work

Example: Walk us through a specific example(s) of how this solution makes a difference; include its primary activities.

We are searching for alternative carbon dioxide free energy sources. Such energy sources could be offshore wind, wave and tidal, photovoltaic, and osmotic power. Statkraft, a Norwegian utility company with a strong tradition in hydropower, has been engaged in technology development attempting to develop new renewable energy technologies. Since 1997 one of these development areas has been to aim at cost-effective Osmotic Power generation. Osmotic power is a relatively new energy conversion concept even though osmosis, a spontaneous process which takes place in all living organisms, has been known for several hundred years. During the 1970s, Sidney Loeb develops membrane technology for the desalination of seawater.

Impact: What is the impact of the work to date? Also describe the projected future impact for the coming years.

Detailed studies have been made of the potential for exploiting this new source of energy both in Norway and in the rest of Europe. The locations included in the potential have a steady availability of fresh water and sea water at one location. This could be at a river outlet, outlet from a hydropower station or other locations as for example the dikes at the European coast. It has also been a crucial factor that the environmental impacts shall be few and of manageable format. This means that for example rivers that could have negative impacts from a decrease in the water flow is excluded from the calculation of feasible rivers for developing osmotic power. In Norway the technical potential is estimated up to 12 TWh/year, equivalent to 10 % of current power consumption in the country. In Europe the similar potential is estimated at 200 TWh/year while the global potential is in the order
Sustainability

Financial Sustainability Plan: What is this solution’s plan to ensure financial sustainability?

Capital cost for an osmotic power plant is relatively high even compared to wind power. However, the osmotic power plant will be designed to operate at full capacity more than 7000 hours a year yielding a power generation capacity which is very high for each MW installed. This reduces the PRO energy cost to an attractive level. Being a renewable energy source with a high environmental performance of the osmotic power technology is viable

Marketplace: Who else is addressing the problem outlined here? How does the proposed project differ from these approaches?

In 2009, the world’s first complete prototype osmotic power plant is constructed at Tofte. The world's first osmotic power plant officially opened january in Tofte in the municipality of Hurum, southwest of Oslo, Norway, providing sustainable, renewable electricity generation 24/7.Unlike solar, wind, wave and other sources of renewable energy, osmotic power plants harness a source of energy that is constantly available--fresh water streams running into the sea--thereby enabling sustainable, renewable power plants that produce constant, uniform electricity, all day, every day
