Fidem Energy Partners with Sojitz Corporation to Expand Renewable Natural Gas Development in North America
FIDEM Energy LLC (“FIDEM”), a developer and operator of biogas-to-energy projects, has announced a strategic partnership with the Japan-based global trading company Sojitz Corporation to accelerate the development of renewable natural gas (RNG) projects across the United States. The collaboration is designed to strengthen the production, commercialization, and global distribution of renewable fuels derived from landfill gas, positioning both companies to take advantage of the rapidly expanding market for sustainable energy solutions.
Under the partnership, FIDEM will leverage its deep expertise in landfill gas management and renewable energy infrastructure development, while Sojitz will contribute its global commercial capabilities, financing strength, and international market access. The alliance reflects the growing demand for renewable natural gas as industries, governments, and utilities seek low-carbon alternatives to conventional fossil fuels.
Expanding RNG Development in the United States
Headquartered in East Tennessee, FIDEM Energy LLC has built its business around the conversion of landfill gas into renewable natural gas, a fuel that can be used in transportation, power generation, and industrial applications. RNG is produced by capturing methane emissions from decomposing organic waste at landfill sites and refining the gas to pipeline-quality standards.
The company’s leadership team brings decades of experience in landfill operations and solid waste management, particularly across the Southeastern United States. This operational background has allowed FIDEM to develop specialized expertise in identifying landfill gas resources, designing recovery systems, and transforming waste-derived methane into commercially viable energy.
Currently, FIDEM owns and operates a landfill-based renewable natural gas facility in Tennessee. The company also holds an extensive portfolio of development rights to landfill gas resources throughout the Southeast. Many of these projects were originally designed and constructed by members of FIDEM’s management team during earlier phases of their careers in the waste management and energy industries.
With these development rights already secured, the company has established a strong foundation for expanding its RNG production capacity. The partnership with Sojitz is expected to provide the additional capital, market access, and strategic support required to scale these opportunities into fully operational facilities.
Building One of the Nation’s Largest Private RNG Platforms
Over the past several years, FIDEM has built one of the largest privately held landfill gas-to-energy platforms in the United States. The company has achieved this by combining technical expertise with long-term relationships across the waste management sector. Through partnerships with landfill operators and municipalities, FIDEM has secured access to methane resources that would otherwise be released into the atmosphere.
Methane is a potent greenhouse gas, with a significantly higher warming potential than carbon dioxide. Capturing and converting landfill methane into renewable natural gas therefore delivers both environmental and economic benefits. It reduces greenhouse gas emissions while simultaneously producing a valuable low-carbon fuel that can be injected into existing natural gas pipelines or used as a transportation fuel.
FIDEM’s strategy focuses on long-term development opportunities. Rather than short-term projects, the company has structured its platform around durable landfill gas rights and multi-decade project lifecycles. This approach enables consistent energy production while supporting long-term investment and infrastructure development.
In addition to project development, the company also works with a network of engineering firms, energy marketers, and infrastructure partners to bring new RNG projects online efficiently. These relationships have helped FIDEM establish a strong pipeline of projects that can be developed over the coming years.
Sojitz Brings Global Market Expertise
Through the new partnership, Sojitz will provide commercial expertise and global market access that complement FIDEM’s technical capabilities. Founded in Japan and operating worldwide, Sojitz has extensive experience in energy trading, infrastructure investment, and commodity marketing.
The company’s global presence and trading networks will help expand the reach of FIDEM’s renewable natural gas production beyond domestic markets. In particular, the partnership could enable RNG produced in North America to serve emerging demand in international markets where low-carbon fuels are increasingly required to meet climate commitments.
By combining FIDEM’s operational experience with Sojitz’s global commercialization capabilities, the companies aim to create a scalable platform capable of developing, financing, and marketing RNG projects across multiple regions.
Accelerating Development Across North America
According to FIDEM leadership, the partnership will significantly accelerate the development timeline for existing projects within the company’s portfolio. Several landfill waste-to-energy facilities are expected to begin construction in the near future as part of the first phase of the collaboration.
The expansion is expected to extend beyond the Southeastern United States, with new development opportunities being evaluated across both the United States and Canada. These projects will focus on converting landfill methane into pipeline-quality renewable natural gas that can be distributed through existing energy infrastructure.
FIDEM President Ben Johnston highlighted the strategic advantages of partnering with Sojitz, emphasizing the global trading company’s experience in international energy markets.
“Sojitz’s extensive trading expertise and global footprint provide a strong platform for accelerating growth across the U.S. and Canada and emerging Japanese and international markets,” Johnston said. “This partnership positions FIDEM to advance its long-term growth strategy, expanding organically while pursuing targeted acquisitions that strengthen our market position.”
Growing Demand for Renewable Natural Gas
The collaboration comes at a time when demand for renewable natural gas is rising rapidly. Governments and corporations around the world are implementing decarbonization strategies that require cleaner energy sources. RNG is gaining recognition as a practical solution because it can be integrated directly into existing natural gas infrastructure.
In the transportation sector, RNG is increasingly used as a low-carbon fuel for heavy-duty trucks and public transit fleets. Utilities are also incorporating renewable natural gas into their fuel supply as part of renewable energy mandates and emissions reduction goals.
Industrial companies, meanwhile, are exploring RNG as a way to lower the carbon footprint of manufacturing operations without major infrastructure changes. Because RNG is chemically similar to conventional natural gas, it can be used in existing equipment with minimal modifications.
These market trends have created a significant opportunity for developers capable of producing large volumes of renewable natural gas from sustainable sources such as landfill gas, agricultural waste, and wastewater treatment facilities.
Long-Term Investment in Renewable Energy Infrastructure
As part of its growth strategy, FIDEM intends to deploy more than $1 billion in capital to develop and expand its renewable natural gas platform. The investment will support the construction of new landfill gas-to-energy facilities, as well as the acquisition of additional landfill gas rights and related infrastructure.
The goal is to establish FIDEM as a leading provider of renewable natural gas for both domestic and international markets. By scaling its platform and leveraging Sojitz’s commercial expertise, the company aims to create a reliable supply of sustainable energy capable of serving transportation, utility, and industrial customers.
The partnership also reflects a broader shift within the global energy sector toward circular resource systems. By transforming waste-derived methane into valuable fuel, landfill gas-to-energy projects contribute to waste management solutions while simultaneously addressing climate challenges.
Positioning for the Future
Looking ahead, the partnership between FIDEM and Sojitz is expected to play an important role in expanding renewable natural gas production across North America. With a strong pipeline of development projects, established landfill partnerships, and increased access to international markets, the collaboration creates a pathway for significant growth in the years ahead.
As the global energy transition accelerates, renewable fuels such as RNG are becoming increasingly important components of the energy mix.
