The Two CHPs

Combined heat and power is a good deal: It is a fine way to drastically reduce waste and derive two uses from a single investment https:/..fr/generique-cialis/.
Combined heat and power (CHP, also known as cogeneration), is familiar to energy managers and building owners. The U.S. Energy Information Agency (EIA) last week posted a very interesting article that digs more deeply into various types of CHP systems and the industries that most often benefit from each.
The post says that there are two types of CHP: topping cycles and bottoming cycles. The difference is explained very well by The Office of Energy Efficiency and Renewable Energy (EERE). Topping cycle approaches use fuel first to generate electricity or mechanical power in a “prime mover” such as a gas turbine or reciprocating energy. Exhaust energy is captured and used for a secondary purpose, such as heating or cooling the facility.
Bottoming cycle systems – which the piece says also is known as “waste heat to power” – heat first is used “to provide thermal input to a furnace or other high temperature industrial process,” with a portion of the heat used for a secondary purpose. This, typically, is a waste heat boiler/steam turbine system, the post says.
The EIA piece has a very interesting chart depicting the industries using CHP and, further, the breakdown between bottoming and topping cycle approaches. In general, bottoming cycle are use in a slightly wider number of industries (chemical; paper, primary metal; petroleum and coal products; food, nonmetallic mineral; crop production; wood product and miscellaneous).
However, topping cycle approaches produce far more energy where they are used. For instance, in the chemical sector, last year bottoming cycle CHP only produced about 1 GW […]
USDOE Launches CHP Accelerator

The US Department of Energy has launched a programme designed to accelerate the uptake of combined heat and power (CHP) in the nation.
As part of the national Climate Action Plan, the Better Buildings Initiative aims to make commercial, public, industrial and residential buildings 20% more energy-efficient over the next decade.
Under its rubric, the new Better Buildings Combined Heat and Power for Resiliency Accelerator, announced last week, aims to boost investment in CHP projects across the country. In collaboration with states, communities, utilities and other stakeholders, the project plans to examine how resiliency planners perceive CHP, identify technology or information gaps that could be barriers to adoption, and develop CHP plans for communities.
So far, 21 utilities, states, counties and cities have signed on to participate, including the states of Missouri, Massachusetts, Maryland and Utah; the cities of Boston, New York, Hoboken and Pittsburgh; and utilities Tennessee Valley Authority and the Long Island Power Authority, as well as Pennsylvania’s Public Utilities Commission.
Northeast coast utility National Grid has joined the initiative and says it will ‘work to support and expand the consideration of combined heat and power technologies for improved efficiency and enhanced resiliency’.
‘The impact of Superstorm Sandy demonstrated the urgent need to design and build more resilient energy systems,’ said Ken Daly, president of National Grid New York. ‘Our partnership with the Better Buildings Combined Heat and Power Resiliency Accelerator helps address that need, aligns with National Grid’s initiative to improve the resiliency of our infrastructure, and provides customers across our service area in New York and New England with more choice when it comes to energy management solutions.’
‘Advanced technologies like combined heat and power will enable the achievement of […]
LA Scrapping Food Waste
Food waste is the single biggest contributor to U.S. landfills, according to the EPA. While some American cities focus on composting, Los Angeles is testing a program to pick up food scraps and convert it to usable energy

Renewable Natural Gas (Biogas) Carbon Credits >$100/Ton
Carbon credit prices breached a $100/ton average for the first time in January 2016.
The Low Carbon Fuel Standard, a California regulation to reduce the carbon intensity of fuels sold in California by ten percent by 2020, is one of the measures adopted by the Air Resource Board, pursuant to Health and Safety Code Sections 38500-38599 (AB 32) to reduce greenhouse gases in California. It is designed to help clean the air, protect the environment, and drive the development of clean, low-carbon fuels to improve California’s energy security and energy independence viagra india.
