Innovative Solutions in a Changing Landscape

CH Four Biogas - Smiths Falls, Ontario, CanadaAs the renewable energy sector undergoes a significant transformation, with new technologies and innovative solutions emerging to meet the growing demand for clean and sustainable energy sources, Claire Allen, P.Eng., VP of Operations at CH Four Biogas, explains how the company has adapted its technology to meet the needs of the North American market.

“We started in 2006, adopting our technology from a Swiss biogas company and modifying it to suit the different feedstocks, temperatures, and equipment available in North America. We’ve since expanded throughout Canada, the United States, Mexico, and South America, primarily focusing on agricultural anaerobic digester projects and co-digestion, which involves using food waste as well as animal manures.”

The process of anaerobic digestion is akin to a stomach breaking down food, with the end product being biogas, primarily composed of methane. “We can use this biogas to generate electricity or clean it to produce renewable natural gas,” Allen explains. “The waste that goes into the process comes out as digestate, an organic fertilizer that can be used to nourish crops.”

As the renewable energy landscape continues to shift, CH Four Biogas has evolved its offerings to meet the changing needs of the market. “When I started with CH Four in 2006, we primarily produced electricity from our gas. Now, we’ve moved into producing renewable natural gas and are exploring the possibility of using our product in vehicles as compressed natural gas,” says Allen. “We’re constantly looking at what the market needs and how we can fit into that. Our technology is a solution for a range of problems, from nutrient overloading in waterways caused by over application of manure to the growing issue of landfill’s reaching capacity waste. We offer a waste management solution that is both green and practical.”

Adapting to a New Normal

The renewable energy sector has seen significant changes in recent years, with the pandemic acting as a catalyst for innovation and adaptation. As the world transitions to a new normal, companies like CH Four Biogas are at the forefront of developing solutions that not only meet the current needs of the market but also contribute to a more sustainable future.

Mohamad Adghim, Head of R&D at CH Four Biogas, shares insights into the current focus of the research and development department at the company. “In light of Canada’s greenhouse gas emissions targets for 2030, our R&D department is concentrating on maximizing the potential of the biogas industry. We’re exploring ways to treat a variety of organic wastes that are typically avoided in digesters, such as corn stover and poultry manure, to optimize their use in digesters and as fertilizers.”

Allen further sheds light on the company’s target areas and the challenges they face in getting their products to market. “We’re currently working with larger farms and industrial anaerobic digester settings, such as municipalities with green bin programs. The material from these programs needs to be pretreated before it can be processed in an anaerobic digester. However, the permitting process can be lengthy, sometimes taking up to two years, which can hinder the industry’s growth.”

As the renewable energy sector looks for innovative solutions, companies like CH Four Biogas are leading the way in developing products that not only meet the current needs of the market but also contribute to a more sustainable future. With a focus on maximizing the potential of the biogas industry and overcoming the challenges of the permitting process, CH Four Biogas is well-positioned to play a key role in achieving Canada’s greenhouse gas emissions targets and fostering a greener, more sustainable world.

CH Four Biogas - Smiths Falls, Ontario, CanadaPioneering the Future of Renewable Energy

CH Four Biogas is not just pursuing theoretical ideas, it has some key projects on the ground that are truly revolutionary. One such project is the one in Prescott, Ontario, a prime example of the company’s commitment to pioneering the future of renewable energy.

Allen provides an in-depth look at the project in Prescott, Ontario. “We’re planning a 600-ton per day food waste and industrial food waste digester. This facility will include a reception building for organics, where we can package and separate inorganics from organics. The process involves two digesters with a hydrolyzer system to pre-treat the organics, an anaerobic digester, and a pasteurizer. The gas produced will be upgraded to natural gas and injected into the natural gas pipeline. The digestate will be certified as an organic fertilizer for land application, providing nutrients to farm fields instead of ending up in a landfill.”

Adghim expresses his eagerness for the project and the ongoing research in collaboration with the University of Ottawa and Algonquin College. “We’re currently researching how to best pre-treat organic wastes like corn stover to optimize their use in the digester. This involves using extrusion to break down the organic material before it enters the digester. Another primary objective of this project is to reduce the size of the digestate and produce clean water that can be safely discharged or reused within the plant.”

He further explains the scalability of the technology and its potential applications. “The technology is easily scalable, which is particularly beneficial for large-scale projects like the one in Prescott. While biogas is not a new technology, its scalability and potential for centralized biogas plants make it an attractive option for waste management. However, the permitting process can be a challenge, as we’ve experienced with our project in Prescott.”

Allen highlights the benefits of such biogas projects. “Our projects can be deployed in various settings, providing access to electricity and heat for those who may not have access to a reliable electricity grid. Biogas is a constant source of energy, unlike solar or wind, which are dependent on weather conditions.”

Navigating the Future of Renewable Energy

The renewable energy sector is at a pivotal moment, with the aging electric grid and the increasing demand for sustainable energy sources driving innovation and growth. CH Four Biogas is angling to be at the forefront of this transformation by developing solutions that not only meet the current needs of the market but also herald a greener and more sustainable future.

Allen reflects on the evolution of the market and the company’s growth. “When I started at CH Four, our clients were primarily small farms, often European farmers who were familiar with biogas technology from living in Europe. Today, we’re working with larger farms, municipalities, and industries that are seeking solutions for nutrient management and waste reduction. The market has changed significantly, and it’s exciting to see the growth and potential of renewable energy.”

Looking ahead, Allen predicts significant growth in the renewable energy sector, particularly in the United States, where tax incentives are driving investment in sustainable solutions. “We’re also seeing growth in Alberta, a province traditionally known for its oil production. There’s a growing interest in diversifying from oil and gas and exploring renewable energy options to reduce greenhouse gas emissions in agriculture.”

Adghim echoes Allen’s sentiments, emphasizing the importance of research and development in driving the industry forward. “Our R&D department is essential in developing the technology and optimizing it to meet the market’s demands. The research in this industry is flourishing, and I don’t see it stopping anytime soon.”

With companies like CH Four Biogas leading the way in developing innovative solutions that contribute to a more sustainable future, the future of renewable energy is bright.
