Cogeneration. Trigeneration cycle Cogeneration or combined heat and power (CHP) is the use of a heat engine[1] or power station to simultaneously generate electricity and useful heat. Trigeneration or combined cooling, heat and power (CCHP) refers to the simultaneous generation of electricity and useful heating and cooling from the combustion of a fuel or a solar heat collector. A plant producing electricity, heat and cold is called a trigeneration[2] or polygeneration plant.
Cogeneration is a thermodynamically efficient use of fuel. The supply of high-temperature heat first drives a gas or steam turbine-powered generator and the resulting low-temperature waste heat is then used for water or space heating as described in cogeneration. Cogeneration was practiced in some of the earliest installations of electrical generation. Cogeneration is still common in pulp and paper mills, refineries and chemical plants.

Wasserwirbelkraft: Wirbel um den Wirbelstrom | Wissen. Neuartige Wasserkraftwerke sollen Energie gewinnen und dabei die Natur schonen. Speichern Drucken Twitter Facebook Google + Am Anfang war die Flut. Im Internet stießen die beiden – er ist Tiefbauingenieur, sie Sozialarbeiterin – auf den Techniker Franz Zotlöterer aus Österreich, der eine alte Idee wiederentdeckt hatte: aus Wasserwirbeln Strom zu gewinnen. Anzeige Und so entstand in Schöftland im Kanton Aargau das erste Wasserwirbelkraftwerk der Schweiz. An diesem Morgen ist die Suhre zahm. Wo heute das Kraftwerk steht, war die Suhre früher in einen engen Kanal gepfercht.
Das Paar hat sich ein Idyll geschaffen: Kater Jimmy streift dem Besucher ums Bein, hinter einem niedrigen Erdwall gurgelt die Suhre. Seit die Schweiz den Atomausstieg auf Raten anstrebt, suchen Politik und Energiewirtschaft nach neuen Stromquellen, auch an Flüssen und Bächen. Die Schweiz hat ein neues Gewässerschutzgesetz erlassen, das sich stark an den Wasserrahmenrichtlinien der Europäischen Union orientiert.
Companies. Articles. Japanese breakthrough will make wind power cheaper than nuclear. NOTE: Some major wind projects like the proposed TWE Carbon Valley project in Wyoming are already pricing in significantly lower than coal power -- $80 per MWh for wind versus $90 per MWh for coal -- and that is without government subsidies using today's wind turbine technology. The International Clean Energy Analysis (ICEA) gateway estimates that the U.S. possesses 2.2 million km2 of high wind potential (Class 3-7 winds) — about 850,000 square miles of land that could yield high levels of wind energy.
This makes the U.S. something of a Saudi Arabia for wind energy, ranked third in the world for total wind energy potential. The United States uses about 26.6 billion MWh's, so at the above rate we could satisfy a full one-third of our total annual energy needs. Now what if a breakthrough came along that potentially tripled the energy output of those turbines? You see where I'm going. Well, such a breakthrough has been made, and it's called the "wind lens.
