biogenic reagents

wed, 08 may 2013 15:05:38 +0000

biogenic reagents is a producer of high-performance carbon products made from renewable resources and produced with renewable energy. biogenic reagents’ specialty products include activated carbons that are used to purify air, water, food and pharmaceuticals. biogenic reagents has engineered a product from renewable biomass that greatly reduces mercury emissions from power plants and industrial facilities. when coal and other fuels are burned to create power, mercury that was contained in the fuel is vaporized into a form (elemental mercury–hg^⁰) which typically is not captured by pollution control systems at these facilities and enters the air where it is later deposited in the environment. biogenic reagent’s propretary process creates a highly oxidative and porous activated carbon material that changes the elemental mercury into a form (mercuric mercury–hg⁺⁺) that may be captured in the many pores of the carbon. in typical use, the biogenic activated carbon is injected as a fine powder into the gas emissions stream at a power plant after where fuel is burned but before a facility’s emission control equipment. through rapid chemical and physical sorption, mercury in the gas stream attaches to the activated carbon allowing it to be captured by typical emission control equipment such as fabric filter baghouses thereby reducing mercury emission to the environment by more than 90 percent.

keeping cool in the community

mon, 10 oct 2011 13:31:47 +0000

district energy systems distribute thermal energy (steam, hot water, and/or chilled water) through a network of underground pipes to multiple buildings in an area, such as a downtown district, college or hospital campus, airport, or military base. by aggregating the heating and air conditioning supply for multiple buildings, district energy systems optimize thermal energy efficiency. they also achieve economies of scale that allow for the use of low-carbon, cost-effective thermal energy sources—such as the “waste” heat from power plants or industrial processes, combined heat and power, geothermal energy, deep lake water, or municipal solid waste and other types of biomass—that may not be feasible for individual buildings. more information is available here.

engineering shelter for a demanding climate

wed, 17 aug 2011 14:30:42 +0000

this video is part of a series of four videos (walkthrough, market appeal, architecture, and engineering) submitted to the department of energy for the competition. to see the rest of the videos, visit our planet forward ideas page. this video highlights the engineering features of self-reliance, team middlebury’s solar decathlon home. from recycled cellulose insulation to reusing condensation to water the plants, the systems of self-reliance are designed to be simple and efficient, while allowing a family to interact with and learn from the technology. this summer the middlebury solar decathlon is building a small, 100% solar-powered home that will compete in the us department of energy solar decathlon 2011 competition. the solar decathlon is a biennial green-building competition that brings together 20 collegiate teams from all over the country and world to showcase their solar homes on the national mall in washington d.c. this competition is one of the most ambitious and inspiring events in the country, as it challenges these teams to demonstrate inventive clean-energy solutions, feature cost-effective and energy-efficient construction, and incorporate energy-saving appliances and renewable energy systems within their 100% solar-powered homes. team middlebury’s home, “self-reliance,” strives to do all this as it reinvents the iconic new england farmhouse, integrating today’s efficient technologies into a home for a vermont family of four. it is our belief that living sustainably can be facilitated by beautiful, comfortable, and practical design. when architecture and technology are used wisely together to utilize the power of the sun and other renewable energy resources, our impact on this earth is greatly reduced. as we construct our solar-powered home this summer we hope to offer a sustainable solution to life in the 21st century. we invite you to follow our construction progress over the next 12 weeks via the weekly videos we will be posting with planet forward. it is our hope to extend this learning opportunity to a greater community beyond middlebury, and inspire others to turn to sustainable design practices as well. please stay tuned! for more information about the middlebury solar decathlon team, please visit http://solardecathlon.middlebury.edu/

we support and lobby for legislation that will provide economic incentives to encourage the construction of district energy and combined heat and power facilities.

fri, 29 oct 2010 15:00:10 +0000

improving the efficiency of energy production from existing central power plants or heating plants with combined heat and power production technologies is a proven means to double the efficiency of fuel use. the fundamental rationale is presented by thomas r. casten, chairman of recycled energy development, llc at the 100th annual conference of the international district energy association, washington, d.c., june 29, 2009.

the members of the international district energy association are pushing the envelope on energy efficiency by combining the production of thermal and electrical energy in central utility plants.

thu, 28 oct 2010 16:49:46 +0000

by combining the production of thermal and electrical energy in central utility plants, district energy systems can reduce the demand on the public electrical grid, especially during peak load periods, while more than doubling the efficiency of fuel use. this video describes how the university of texas at austin, one of the largest public universities in the u.s., has not increased its fuel costs–achieving carbon-neutral growth–while providing all of its own electric power and adding a staggering 7 million square feet of heated and cooled building space to accommodate growth in student enrollment.

district energy systems can leverage scale and alternative energy to power cities

thu, 28 oct 2010 14:09:03 +0000

build more district energy systems, because they have the inherent scale and load aggregation to consume biomass as well as fossil fuels and to use unique resources such as deep lake water to replace air conditioning equipment.

district energy distribution systems–consisting of underground piping grids–provide efficient thermal arteries for the distribution of steam or hot water for heating and chilled water for cooling many buildings. this video, made in 2003, explains how enwave constructed a deep lake water cooling(r) system that provides the equivalent of 62,000 tons of air conditioning to cool hundreds of buildings in downtown toronto. the system literally cleared the air of pollutants by replacing the electrical demand of huge chillers from fossil-fired utilities with the much lower demand to run simple pumps that move cold water through a heat exchanger system.
