Sustainable Independent Energy
from Emerald Power

Achieving sustainable energy independence depends on meeting the challenge of global climate change while also reducing the cost of energy. Such a green standard is greener than previous generations envisioned. Emerald Power can realize the vast potential energy locked in wastes and wasted energy, which is how Emerald Power avoids cost and pollution and why Emerald is greener than green.

By distributing ultra-efficient electric generation at local sources of waste or wasted energy, Emerald Power can convert local operations that depend on oil, coal, or gas into operations that produce independent, ultra-efficient, clean energy. Such greener-than-green power produced on site will also relieve growing demand put on central-power plants and electric-utility grids and thereby avoid more costs for energy.

By producing multiple forms of clean energy from carbonaceous waste on site (hundreds of megawatts from New York City solid waste and biosolids alone) or producing gigawatts of electricity from pressure “let down” by natural-gas pipelines, or separately recovering virtually all methane and carbon dioxide from landfill gas (LFG), digester gas, or wellhead oil and gas, Emerald Power can dramatically reduce emissions and costs on site at existing waste-management or energy operations.

Emerald’s knowledgeable team of engineers, each with decades of experience in designing ultra-efficient processes and bringing them on line, enables Emerald to deliver safe, reliable energy through three core technologies:

• Anaerobic Thermal Conversion "ATC"
  Produces energy from waste without incineration


• Greenhouse-Gas Recovery
  Separately captures and purifies methane and carbon dioxide


• Pipeline-Pressure-Let-Down Recovery
  Makes electricity with over 70% efficiency

Emerald designed a system using the ATC to process wastewater comprising as little as 2% biosolids. Emerald is also offering ATC systems for municipal solid waste, scrap tires, agricultural waste and manure, infectious waste, and construction-and-demolition debris. Products from these ATC systems include electricity, high- and low-pressure steam, and high-quality synthetic gas.

Densely populated cities like New York, experiencing a growing demand for electricity in load pockets, can recover as much as 100 megawatts of electricity through Emerald’s Pipeline-Pressure-Let-Down Recovery. And landfills can produce both 970-BTU, pipeline-quality methane and commercial-grade carbon dioxide while also separating virtually all contaminants for hazardous-waste disposal off site.

By developing, financing, building, maintaining, and operating on-site ultra-efficient clean-energy processes, Emerald can help public and private operations eliminate the financial risk of upgrading operations while also offering fixed, long-term, competitive prices.
