Title:  SARE Gas Clean Up

Title:  Capturing waste heat from biogas-powered generators for conductive cooling on NYS dairy farms

Sponsor:  New York State Energy Research Development Authority

Dates:  11/1/2012 to present

Overview:  The main goal of this research is to develop a novel cooling system for the abatement of heat stress in dairy cattle using the excess waste heat produced by a combined heat and power engine burning digester biogas (CHP-DG).  At the same time, our goal is to maintain or reduce electricity consumption on the farm to ensure the economic incentive of electricity net metering is maintained or improved.  In essence, an absorption refrigeration system will capture the excess waste heat from the CHP-DG, thereby, generating a stream of chilled fluid, which will feed a conductive cow cooling element placed below the bedding in cow resting areas to alleviate heat stress.  An economic analysis and life cycle assessment of the entire cooling system will be performed for comparison with conventional cooling systems.  The results of this study will be of immediate value to farm managers and dairy industry advisors for use in developing adaptive strategies to deal with heat stress on NYS dairy farms. The PRO-DAIRY extension program will be the primary agent for disseminating study findings and to address dairy industry members’ concerns.  The exciting features of the proposed cooling system are its minimal utilization of energy and water resources compared to conventional cooling technology (e.g., fans/sprinkler systems), and its simultaneous adherence to renewable energy principals and sustainable agriculture practices.

Title:  CEA Synergy Project

Title:  National Facilitation of Extension Programming in Climate Change Mitigation and Adaptation for Animal Agriculture

Sponsor:  USDA


Overview:  The overall goal of the proposed project is that Extension, working with partner organizations, effectively informs and influences livestock and poultry producers and consumers of animal products in all regions of the U.S. to move animal production toward practices that are environmentally sound, climatically compatible, and economically viable. A primary desired outcome is that stakeholder decisions result in reduced greenhouse gas emissions without sacrificing America’s capacity to produce meat, milk, eggs and other animal products.

Project objectives are to:

  1. Equip extension personnel and stakeholder representatives to assess stakeholder needs relative to climate change mitigation and adaptation and to deliver educational programs that target those needs;

  2. Provide on-demand web access to science-based information, educational resources, and decision-support tools to stakeholder groups and the public on climate change related to animal agriculture; and

  3.  Coordinate efforts so information and resources are utilized optimally at the state, regional and national levels.
