WEROP - wave energy reverse osmosis pump

Wave energy converter using the energy directly to power a variety of hydraulic processes including desalination, aquaculture, mineral recovery and power generation. Supplies high pressure pre-filtered seawater for these processes.

Stage 3: Proof of Concept

The WEROP has been successfully demonstrated at sea since 2004. IFW are now scaling & working on an improved energy off-take to take advantage of the high energy seas around the Southern African shores, while working to commercialize the technology.

Registered as a For-Profit in South Africa.

1.Water scarcity; 2. power shortages or expensive power; 3. Cost of pre-filtration and delivery of clean seawater to the coast for industrial use such as seawater desalination, salt recovery and land-based aquaculture; 4. Cost of cooling industrial applications and controlled agricultural processes (growth cycles, office/hotel space cooling, general industrial cooling applications). 5. Cost of fouling in intake pipes (aquaculture, desalination etc.).



The WEROP uses wave energy directly to supply pre-filtered high pressure seawater to an industrial process such as a Reverse Osmosis system, producing fresh water as a primary product and electricity and salt as by-products. The high pressure delivery is the most efficient way to supply wave energy. It also prevents bio-fouling in the pipeline. The system also forms a reef, and the system reduces incident wave energy, thus reducing coastal erosion. All this and more with zero electricity usage.

Target Beneficiaries

Isolated indigent communities; urban and rural coastal communities with enough wave energy. My aim is to form a non-profit public beneficiary company to use a 1/3 of the profits of the commercial company to provide isolated indigent communities with potable water in a sustainable fashion. We will look for win-win ways to help while still making our shareholders wealthy.

Mission and Vision

Reduce diseases and suffering associated with a lack of access to enough potable water. Provide alternative to dirty fuels and an example for doing business in a truly sustainable fashion - the triple bottom line: economic, social and environmental win-win symbiotic relationship.

Innovation Description

The system uses the orbital motion of passing ocean waves to drive a simple seabed based pump. The water is drawn through a filtration system and then pressurised to over 70 bars and pumped to a shore based process such as a desalination and power generation plant.

Competitive Advantage

The system is cost efficient and green. IFW strives to make wave energy affordable. We do this by cutting out the need for specialist installation equipment, such as jack-up rigs. The system also offers a unique feature: pre-filtration. The system uses wave energy directly to drive the pumping of seawater to the shore for industrial purposes such as SWRO desalination, power generation and cooling. The system provides the seawater at over 70 bars on the land for this purpose. The systems are modular and scalable and can be moved if desired.

Planned Goals and Milestones

Upgrade the power offtake to take advantage of the high energy waves around the Southern African shores. We have been awarded a government grant. We plan to deploy the new system in September 2019. We also recently signed the terms to another Government grant to scale the technology for a semi-commercial demonstration project in South Africa. We hope to start in June. We are also engaged in negotiating a joint venture with the University of Namibia to demonstrate the WEROP in Henties Baai.
