1 Community- Scale Hea1ng with Woody Biomass in New Hampshire Local Energy Solu1ons Conference April 12, 2014

2 Overview How NH Heats Benefits of Hea1ng with Woody Biomass About Biomass/Sustainability of the Resource Technology Boilers/ Fuel Delivery Real NH Projects Economics Heat Cost Comparison How NH Wood Energy Council Can Help You

3 How Does NH Heat? Fuel % Households # Households Hea1ng Oil 48.8% 252,000 U1lity Gas 19.5% 101,000 BoYled Gas/ Propane 14.4% 74,000 Electricity 7.9 % 41,000 Wood 7.2% 37,000 Other (e.g. coal, solar) 2.1 % 11,000 Source: US Census Bureau ACS, 2010

5 Wood Pellets Biomass Fuels Wood chips Wood or grass briqueyes Logwood

6 Benefits Save $$$ on hea;ng cost Keep fuel dollar in local economy we export $1 BILLION annually for fossil hea;ng fuels Reduce dependence on imported oil/propane Reduce greenhouse gas emissions, wood is low carbon fuel in comparison to fossil fuels Support strong markets for low- grade wood keeps forests undeveloped Create jobs in New Hampshire Reduce certain air pollutants (e.g. SO2, Hg) RENEWABLE, SUSTAINABLE

7 Advanced Wood Hea;ng Systems Controlled combus1on engineering Fully automated fuel storage and conveying Fully automated ash handling Computer controls and monitoring Emission controls to meet stringent standards Hot water or steam at range of pressures Can be combined with thermal storage and other renewable technologies (e.g. solar hot water) NOT YOUR GRANDFATHER S WOOD BOILER! Don t get discouraged by anecdotes of past failures technology is advancing rapidly!

8 Bulk delivery of wood pellet fuel

9 Wood chip transport and delivery Generally by live- floor trailers that dump into large fuel storage bin, usually under cover
