Bioenergy > Technologies > Cogeneration/Combined Heat and Power (CHP)
Cogeneration (also known as co-generation or combined heat and power, CHP) technologies generate both heat and electricity. Cogeneration is a method of the production of energy in the form of electricity and heat from biological materials including both biogas and biomass.

News
- MA Proposes GHG Restrictions on Biomass Power, 11 May 2011 by RenewableEnergyWorld.com: "The Massachusetts governor's office last week said the biomass electricity industry must meet strict emissions standards if wood-fired power plants expect to earn renewable energy credits (RECs)."
- "Gov. Deval L. Patrick and Lt. Gov. Timothy P. Murray proposed the restrictions before the Legislature this week after the Massachusetts Department of Energy Resources (DOER) revised the Renewable Portfolio Standard (RPS) to account for the findings of an independent study."
- "In June, the DOER-commissioned study by the Manomet Center for Conservation Sciences of Plymouth concluded that large-scale, biomass-fired electricity would create 3% more greenhouse emissions (GHG) than coal-fired plants by 2050."
- "Massachusetts, officially a commonwealth, is among the first states to regulate biomass emissions. The Environmental Protection Agency tabled the issue for three years when it announced in January a three-year deferral on GHG-permitting requirements."
- "DOER officials hope the restrictions will encourage the biomass industry to design smaller projects for combined heat and power (CHP) units, which can provide heat and electricity for industrial parks and community districts. The Manomet study found that CHP would reduce GHGs 25% by 2050."[1]
- Montpelier building biomass district energy system, 8 February 2011 by Biomass Power and Thermal Magazine: "With the help of an $8 million Recovery Act grant, Vermont’s capital city will install a 41 MMBtu combined-heat and-power biomass district energy system that will provide heat to the statehouse and up to 175 other public and private buildings downtown, as well as 1.8 million kilowatt hours of electricity to the grid."
- "Locally sourced wood chips will fuel the plant. In terms of how much a system like this would require, Sherman said it’s a moving target dependent on what the final build-out of the system is, but it will not be a huge volume—somewhere from 10,000 to 15,000 green tons annually."[2]
- IFPRI Publishes Study on the EU Biofuels Mandate, by The International Food Policy Research Institute: "The report is one of four commissioned by the European Commission to assess the impacts of the 10% target for the use of renewable energy in road transport fuels by 2020."
- "The study uses a global general equilibrium model, separately including numerous first generation ethanol and biodiesel feedstocks, co-generated products, farming techniques, as well as direct, and indirect land-use changes (ILUC) resulting from the mandated increase in consumption of biofuels. Additionally, as the model is global, it also considers different multi- and bilateral trade scenarios."
- "The results indicate that there is ILUC associated with the EU mandate, but that the mandate will still result in global greenhouse gas (GHG) emission savings of nearly 13 million tons over 20 years. Additionally, the authors find that the mandate will have only a negligible effect on food prices and, concerning biodiesel, even with ILUC taken into account, imported palm oil remains as efficient as European rapeseed."[3]
