Meet our members
Our members develop technology, do research, develop projects, deliver services and sub-systems and invest in the field of hydropower, tidal energy, wave energy, OTEC and salinity gradient. Together we conduct campaigns, share knowledge, organize meetings, conferences and do (market) research.
Low head water turbines
EQA's mission is to contribute to the respectful harvesting of (sustainable) sources of energy that are given to us by nature. We support the transition from fossil fuels to sustainable energy.
It is mandatory in our company to do everything with the environment in mind. Our solutions are proven fish-friendly and certified.
Wave energy converter
Hans Lustig and Sten Swanenberg have developed a simple wave energy converter with a focus on cost reduction.
Sten: "The heart of DWP consists of a cylindrical float and an internal pendulum system to convert energy when the float rotates back and forth on the waves. We have tested various models extensively in the Deltares Wave Flume and last year in MARIN. We are now preparing our sea pilot for the coast near Scheveningen via Campus@Sea."
Low head water turbines
FishFlow Innovations develops water-related inventions for the world of tomorrow. Our mission is to protect underwater ecosystems and provide clean energy from hydropower. Our products offer new solutions for fish migration and help prevent mortality and damage. By focusing on the natural behavior of fish, FishFlow Innovations is the ideal partner for water boards and hydraulic engineering organizations that value the welfare of fish.
KNSWING
Wave energy converter
The KNSwing, conceived by Kim Nielsen, can generate energy on a large scale in WEC farms and on a smaller scale in floating breakwaters to supply power to ports, for example.
MEA partners ECN, EMEC, MaREI and MARIN are helping to further develop the technology. Kim is looking for help in developing the air turbines and electrical systems for the floating breakwaters. Interested in working with us? Contact Kim Nielsen!
Tidal stream kite
SeaQurrent develops the TidalKite, an underwater kite for sustainable electricity production from tidal and ocean currents. Tidal energy is reliable, predictable, available daily and therefore the cheapest option for continuous sustainable electricity. The unique 3D harnessing makes the TidalKite widely applicable, also in shallower Dutch coastal waters with lower current velocities.
Wave energy converter
The Slow Mill consists of a float with blades that are variably connected to an anchor on the seabed. Waves push the float up and the blades away from the anchor. In this way, not only the up and down movement but also the back and forth movement of the waves is used. The entire unit follows the orbital or sometimes elliptical wave path, but when taking the inside bend it goes a little slower than the wave, hence the name: Slow Mill.
Wave energy converter
Symphony Wave Power is a new technology based on more than 20 years of experience in the development of wave and tidal technology. The technology is a product of co-makership between science and industry led by Teamwork Technology BV in the Netherlands. It represents the know-how of a network of expertise in Europe and beyond. Developed with support from the European Commission and with expertise in the offshore industry.
Salinity gradient power
Blue Energy is well known for generating 24/7 CO2-freesustainable electricity from salt and fresh water, thus improving grid stability in the sustainable energy mix.
A demo pilot is operating successfully on the Afsluitdijk. This pilot is planned to be scaled-up in the coming 3 years.
On the basis of this technology REDstack now offers energy-efficient, leak-free and industrially produced ElectroMembrane Stacks as a platform technology for resource recovery. Markets served range from Nitrogen recovery, Carbon Capture, Lithium recovery and power storage. These ElectroMembrane Stracks are commercially available and already show significant sales.
Tidal turbines
W2E designs and builds water turbines. Our technology is proven for locks, docks and dams or open water. Robust, efficient and fish-friendly. Our team builds on years of experience in tidal energy and offshore engineering. We develop a range of turbines that produce energy at a cost level that is competitive with solar or wind energy, but more reliable and predictable! W2E for reliable and sustainable energy solutions!
Wave energy converter
Weco is a young start-up with big plans. We have a vision in which the Netherlands, Europe and the world are supplied with electricity from waves at sea. By combining wave energy with other technologies such as offshore wind, not only is space at sea saved, but the security of supply is also improved. In this way, we provide a sustainable but also affordable future for our children.
Wave energy converter
The Wavehexapod is a hexapod with 3 buoys and 6 generators. The generators hang on a fixed suspension mechanism to a larger submersible that can hang up to 9 hexapods.
With the hexapod we can follow the waves as well as possible to extract energy from them. Both in the up and down movement and the horizontal movement.
The Wavehexapod is well suited for use in offshore wind infrastructure, but also as a stand-alone solution.
Project developer
Blue Energy Concepts BV (BEC) is a young project organisation that focuses on the (support of the) development of sustainable technologies based on Energy from Water (EuW). The focus is on ecologically and economically responsible forms of EuW.
BEC supports entrepreneurs on a technical, organizational and financial level and leads their organizations on a project basis from an early development phase to commercialization.
In addition, BEC supports organizations that want to realize projects with energy from water.
Project initiation and management
Bluespring, founded by Peter Scheijgrond, helps technology developers, research institutes and governments to get their water energy projects financed and implemented, with a focus on practical pilots, test setups and demonstration projects.
With over 25 years of experience in technology development in the sustainable energy sector, Bluespring knows how to set up, finance and implement complex, often international collaborative projects with impact.
Project realization & advice
Cubic Square stands for Spatial Realizations. Research and guidance should be focused on doing: establishing and making a water project feasible.
In this, Cubic Square is experienced in all forms: role and tasks of governments, permits, geology and hydrology, market, technology, tendering and execution. Everything under the direction of the government, but focused on turnkey and yield maximization. A condition for this is often early involvement and linking of multiple works in civil engineering or construction.
Synthetic Cables
Since 2009, FibreMax in Joure, Netherlands, has been producing the world's strongest synthetic cables.
“At FibreMax, we lead in innovation and technology, supporting wave, tidal, and floating wind projects. We have successfully delivered custom tether solutions for several wave and tidal projects for clients such as Minesto, SeaQurrent, Seatricity, Cairenergy, Bladerunner, and more,” says Sander van Helvoort, Business Development Manager Renewable Energy at FibreMax.
