Energy supply is the delivery of fuels or transformed fuels to point of consumption. It potentially encompasses the extraction, transmission, generation, distribution and storage of fuels. It is also sometimes called energy flow.

The Strongest Link in the Chain

Renewable energy—and solar energy in par­ticular—has a problem. Because it is subject to the vagaries of sunshine and wind for power generation, it is often not available when it is needed most. For those nighttime hours when the sun is not available and cloudy days when sunlight is minimal, provisions

The Physics of CHP Cogeneration and Heat Engine Efficiency

The Physics of CHP Cogeneration and Heat Engine Efficiency

How does CHP work? To understand CHP you have to begin with the Carnot cycle, and how it describes the function and efficacy of any heat engine. The thermodynamic Carnot cycle (proposed by Nicolas Carnot in 1824) is a four-stage process that describes the reciprocal operations of a heat engine

Elements of Critical Power Systems and Their Management

A single power interruption can cripple a healthy company, says Bhavesh Patel, director of marketing of Emerson’s ASCO Power business. “Not having adequate onsite power can be the ‘Achilles heel’ of a business, but the controls for operating, monitoring, diagnosing, and producing a variety of mandatory reports on these power

Fronius Installs Inverters in a Former Nuclear Power Plant

Fronius, the global quality leader for solar energy, has carried out a very special project in Zwentendorf, Austria: a photovoltaic system has been installed on the site of a former nuclear power plant (NPP). Where once nuclear energy was to be produced, today clean, safe energy is generated from natural

Making Power Multitask With CHP/CCHP

Making Power Multitask With CHP/CCHP

Cogeneration, or combined heat and power (CHP), uses a heat engine or power station to generate electricity and heat for onsite uses. Trigeneration, or combined cooling, heat, and power (CCHP), is the simultaneous generation of electricity and useful heating and cooling as a result of the combustion of fuel or

SEPA Releases New “Distributed Energy Resources Capabilities Guide”

SEPA Releases New “Distributed Energy Resources Capabilities Guide”

The Smart Electric Power Alliance (SEPA) announces the publication of a new report, “Distributed Energy Resources Capabilities Guide,” the third release of its Beyond the Meter series focused on energy system transition.

The guide covers the technical capabilities of distributed energy resources (DERs) — including solar, storage, energy efficiency and demand

A Second Life for Used Batteries

Hamburg/Munich/Stuttgart – What should be done with still-usable batteries at the end of their life cycle in electric vehicles? The Battery 2nd Life project organized by Vattenfall, BMW and Bosch merges them into a large storage facility in Hamburg, Germany, to keep the electricity grid stable.

Storage stabilizes the electricity grid
