Tag: CHP systems

Combined heat and power (CHP) is an efficient and clean approach to generating electric power and useful thermal energy from a single fuel source. CHP is used either to replace or supplement conventional separate heat and power (SHP).

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

Integrating CHP with Microgrids

Integrating CHP with Microgrids

While combined heat & power (CHP) may not be appropriate for integration into all microgrids, it definitely does have its place in a lot of them.

CHP systems output heat (or cooling), as well as electricity, primarily as a topping cycle. “The prime mover is typically a reci­procating engine or a turbine,”

Fuel Cells and Energy Sustainability

Fuel Cells and Energy Sustainability

Given that energy sustainability and energy economics are top-of-mind among business leaders, politicians, and the public these days, hydrogen fuel cells may be viewed as a savior technology. If that statement seems hyperbolic, there is plenty of statistical evidence to support the growth of fuel cell use for both stationary

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

Why Microgrids Are Inevitable

Why Microgrids Are Inevitable

The fledgling electric utility companies that emerged after Thomas Edison opened his small Pearl Street, New York City, NY, power station in 1882 originally focused on distributed energy generation (DEG) operating within a microgrid. Edison envisioned that the electric utility industry would involve small firms generating direct current (DC) power

Better Together

Better Together

“Waste not want not” is a respected proverb in many engineering applications. However, according to the three laws of thermodynamics, waste heat is inevitable in any working system. And, while it is physically impossible to prevent the generation of waste heat, a power system operator can make a virtue out

Power Partnerships

Power Partnerships

Synergy, from Greek sunergia, meaning “cooperation,” is the collaborative interaction of two or more parts of a system so that the combined effect is greater than the individual efforts. In business and technology, the term often refers to the way system components work together to optimize efficiency and heighten productivity. Some
