Overview � Basics � What is Renewable Gas? � How is it produced? � Why should it be considered � What is the Potential? Vision? � Demonstration project � Policy issues 2
What is Renewable Gas? � Pipeline quality gas derived from biomass resources that is injected into the gas distribution network � Sources of biomass include wastewater treatment plants, landfills, livestock manure, municipal solid waste, agricultural residues and energy crops Feedstock Anaerobic Digestion / Upgrading, Injection of Gasification clean-up, pipeline quality methanation gas 3
How is Renewable Gas produced? Anaerobic Digestion (AD) Thermal Gasification (TG) � High-moisture organic material � Low-moisture feedstock such such as wastewater, food as forestry waste, crop waste & certain livestock residue, municipal solid waste manure and energy crops � Microorganisms convert � Thermal breakdown of solid organic matter into biogas biomass into syngas and converted to methane � Commercially available and in � A proven technology likely to use today reach commercial-scale implementation within 10 years 4
Why should it be considered? Renewable Gas is a here and now energy solution that delivers the following benefits: � Lowers greenhouse gas (GHG) emissions by offsetting the use of natural gas (and in some instances capturing methane that would have otherwise entered the atmosphere) � Provides a real option for managing and using local waste resources to produce renewable energy � Leverages the existing natural gas network to deliver a renewable fuel for homes, business, industrial, and transportation needs � Stimulates the local economy and creates jobs � Enhances diversity of supply with a local and domestic resource 5
Renewable Gas is interchangeable with natural gas for everyday uses in our homes and businesses Fireplaces Gas Ranges, Ovens & Cooktops Hot Water Fleet Vehicles & Public Clothes Dryers Transportation Cars, Trucks, Vans & SUVs Furnaces 6
What is the potential? Recent study by American Gas Foundation (released Sept. 2011) Finding: Under a reasonable long-term scenario, Renewable Gas could be used to meet the natural gas needs of half of all American homes. AGF Study Scenario Category Non-Aggressive Aggressive Technical Potential Energy Potential (billion 967 2,485 9,450 cubic feet /yr) Potential as a Percentage Overall 4% 10% 40% Demand * CO 2 Abatement 57 146 556 (million tons/yr) Direct Jobs Created 8,825 – 32,189 22,692 – 82,765 86,732 – 316,338 (low – high range) * Based on a national usage of approximately 24 TCF of natural gas (for 2010), source EIA 7
Vision for a sustainable gas network 8
Newtown Creek demonstration project � National Grid and New York City Department of Environmental Protection are working together to deliver renewable gas from the largest wastewater treatment plant in New York City � Once operational, the project will inject enough gas to provide heat to approximately 2,500 homes and reduce CO2 emissions by about 16,000 tons annually (equal to CO2 Picture of Newtown Creek waste water treatment plant in Brooklyn, NY. emissions of approximately Source: New York City Department of Environmental Protection 3,000 cars) Note: project requires regulatory approval 9
What needs to happen to realize the potential? Federal & State policy support will be a critical factor in delivering the potential of renewable gas. Concepts should include: PARITY The playing field needs to be leveled so that Renewable Gas is valued, supported and incentivized in ways equal to renewable electricity or liquid transportation fuel ACCESSIBILITY AND INTEGRATION Our nation’s pipeline infrastructure should facilitate the purchase and transfer of Renewable Gas in order to more easily meet local, state, or federal goals for renewable fuel 10
