Mainspring Energy announces first LFG project

Mainspring Energy announces first LFG project
Mainspring’s linear generator is designed to enable high expansion of reacted gases and to electrically control the conversion of linear motion directly into electricity. The high expansion allows for maximum extraction of reaction energy, and direct conversion eliminates mechanical losses — combining to enable high-efficiency operation across all power output levels from 0 to 100 percent (photo courtesy Mainstream Energy).

In the United States, clean power generation provider Mainspring Energy Inc. has announced that it has entered into an agreement with Yolo County, California, to pilot a Mainspring Linear Generator running landfill gas (LFG) at the Yolo County Central Landfill (YCCL).

In its first 100 percent landfill gas pilot project, to be deployed in the upcoming weeks, the Mainspring product will run on landfill gas (LFG) produced by the landfill to generate electricity that can be used for site operations or exported to the grid.

LFG is a byproduct of the decomposition of organic material in landfills, and when not controlled, produces significant amounts of methane emissions.

Municipal solid waste landfills are the third-largest source of human-related methane emissions in the United States (US). These landfills provide an important opportunity to capture and sustainably use this significant energy resource to generate renewable electricity.

In turn, this can reduce emissions and prevent methane from migrating into the atmosphere and contributing to local smog and global climate change.

One big advantage of a fuel-agnostic generator design is the ability to convert biogas from a number of agricultural and waste management operations into useful, renewable electricity. We are honored to be working with an innovative municipality like Yolo County to unlock the potential of Mainspring’s technology in this important global use case, said Shannon Miller, CEO, and Founder of Mainspring Energy.

Yolo County Central Landfill

The Yolo County Central Landfill (YCCL) has made significant innovative strides over the last 30 years to reduce the amount of waste going into the landfill, capture emissions, and provide a myriad of recycling and reuse services for the surrounding community.

The YCCL operates with an average annual budget of US$39 million that encompasses landfilling operations, green and food waste composting, landfill gas control and electricity production, environmental compliance, capital improvements, and administration.

The Mainspring project is the latest in a series of efforts by the YCCL to increase power generation and reduce greenhouse gas (GHG) emissions.

The pilot project will provide important real-world system experience as Yolo County evaluates the fuel-flexible linear generator technology in its biogas system.

We are excited to partner with Mainspring and continue to demonstrate the production of renewable electricity using a new and innovative technology that has the potential to increase the efficiency of electricity production and reduce air emissions, said Ramin Yazdani, Director of Integrated Waste Management at Yolo County.

Fuel flexible technology suitable for biogas

Landfills represent just one type of biogas system. Biogas systems recycle organic waste of many kinds into renewable energy while reducing GHG emissions.

According to the American Biogas Council (ABC), the US has currently 2 300 biogas-producing sites in 50 states, including landfills, farms, wastewater treatment facilities, and systems that digest food scraps.

The country currently has the potential to build 15 000+ new biogas systems, creating an infrastructure capable of producing enough electricity to power nearly 10 million homes.

According to the company, the Mainspring Linear Generator’s fuel-flexible, modular design is ideally suited for a biogas system to help meet this tremendous potential.

It is dispatchable so it can ramp up and down with changing power requirements, modular so it can be easily sited and scaled to different capacities, and fuel-flexible to run any gaseous fuel.

The fuel flexibility is particularly helpful in biogas operations, as biogas streams and energy content can change over time depending on feedstock variability and ambient conditions.
