Turbines driven by ocean waves

Turbines driven by ocean waves

Prototype Turbine

Professor Tsumoru Shintake of the Okinawa University in Japan intents to develop small turbines that generate electricity from the power of the flowing water.

Professor Shintake: “Using just 1% of the seashore of mainland Japan can [generate] about 10 gigawatts [of energy], which is equivalent to 10 nuclear power plants. That’s huge. It is especially huge in Japan, where nuclear power has a somewhat mixed track record.”

Floating Power Plant

Floating power plant

The platform rotation is secured via the high wave absorption of 60-80% of the inherent energy in the waves.

This Floating Power Plant is targeting 
20GW, corresponding to €50bn potential revenue. The Power Plant is offshore proof and grid connected.

Denmark is convinced that this wind- and water energy plant is a significant step forward in world challenge to change into renewables. Read More

Dutch engineers want to optimize these turbines and supply the station with more turbines. Enough for two thousand households

Last week. the tidal power station in the Dutch Eastern Scheldt commissioned.

From now, five water turbines supply power to the grid.

The turbines are generating enough electricity for over one thousand households.  Read More

City heat grid uses waste heat from paper industry

Heat Recovery In Industrial Refrigeration efficiency and cost-effectiveness of their utility infrastructure.

Heat recovering Industry system.

Paper factorySappi can not use the heat which is produced during the proces, itself.

Therefore the waste heat is sent to the power company and ‘recycled’ to produce heat and cold for homes and businesses in the city of Maastricht. Read More

Finally: solar needles make fuel from water

Nano, hydro gas, oxygen gas, renewables, polymer, TU Eindhoven

Solar needles of gallium phosphide, can cleave water, to hydrogen gas and oxygen gas.

It seems pure alchemy, but it’s solid science:

Researchers managed to create fuel directly from sunlight and water. In an article in Nature Communications last Friday, they presented nanowires, pulling hydrogen from water molecules.  Read More

Thermal energy storage saves 90% heat

The first Ecovat Thermo Energy Storage Tank almost ready for use

The Dutch startup Ecovat is making the energy supply in the built environment sustainable, by creating a large thermal storage tank that is able to store high temperature heat (to around 90 degrees C) over a longer period (> 6 months) with a loss of energy in this period of less than 10%.

Dr. Ir. J van Berkel (TU/e) has confirmed this in a desk research. (Report “Ecovat Thermodynamics”, March 20th, 2014).  Read More

Water tank retains > 90% thermal energy

Ecovat expects to be able to retain more than 90% of thermal energy and more than 93% of ‘exergy’ over a period of 6 months.

The Dutch startup Ecovat wants to link the heat waste market to the renewable energy market.

A revolution to heating, cooling and thermal energy storage.

Hydrea Thermpipe delivers energy from the sewer

sewage, waste water, heat recovery, green city, electricity, water, sustainable infra, CO2, Footprint,

This is a durable and efficient solution, which fits excellent in the pursuit of energy-neutral cities. Just 150 meters Hydrea can supply heat to 100 homes.

Sewage water is relatively warm. In stead of using fossil fuels to heat your building or home, Hydrea Thermpipe generates renewable energy, using the heat from waste water.

Boosting Capacitive Blue-Energy and Desalination Devices with Waste Heat

Energy from seawater

Red power plant Blue Energy

The energy output of blue engines can be increased by a factor of order 2 if warm (waste-heated) fresh water is mixed with cold sea water.

Moreover, the underlying physics can also be used to optimize the reverse process of capacitive desalination of water. Read More

Hydrodynamic screw reverses for renewable energy

Hydro power, renewables, landustry, turbine, water fall

Water from the lake at Penllergare Valley Woods flows downwards to the river below, turning the screw to produce electricity.

With rising energy costs, not only is industry looking for energy-saving solutions, but even better are energy-producing solutions. Hydrodynamic screws are a low-cost, environmentally sound way to generate energy. Their origins go back to ancient Greece. Andritz Atro gave the original disign a new twist. Read More

WavePower: This Florida company comes with a Deep Ocean Energy Turbine

New: A Deep Ocean Wave Power Turbine from Florida

New: A Deep Ocean Wave Power Turbine from Florida

Power generating turbines with running under water on the flow of the water. That Crowd Energy achieved through a campaign on IndieGoGo. The project was detailed to the folks at Livescience, with the goal being to create turbines deep in the ocean that use currents to generate power. Crowd Energy was founded by Todd Janca, who came up with the idea and discussed it in detail recently.  Read More

Hydropower screw turbine for nature park

Hydro power, renewables, landustry, turbine, water fall

The hydropower screw turbine is a fish friendly, efficient device for converting the potential energy in water to electricity.

Landustrie delivered a hydropower screw turbine to the Penllergare Valley Trust in Wales, UK.

The Trust welcomed the screw turbine as its electricity production is an important financial corner stone of the wood’s restoration program.  Read More

Unlimited WavePower: Promising Mini Model

This WavePower Generator mini-model is the first to use the whole elliptic way of movement of the waves. And by that takes the full advantage of the wave energy in order to produce electricity. Fully patented, the most efficient device for producing electricity from wave’s energy.

The wave energy potential is

  • 10 times greater than wind energy
  • more than 100 times greater than solar energy

The WavePower generator is capable of gathering almost 30% of the waves energy potential.


Maintenance and repair costs

Prior calculations show that the total cost of energy (financing, building and maitenance) for 20 years should be around USD 0.02/KWh.
