General information about renewable natural gas programs
The demand for renewable energy has skyrocketed in recent years. In fact, the world’s energy demand has surged since the industrial revolution and is projected to increase by 28% in less than 25 years (info 6). Renewable natural gas (RNG) programs have emerged as a crucial part of the solution to meet this growing demand while also reducing our carbon footprint.
Technologies used in RNG and biogas production
Anaerobic Digestion
Anaerobic digestion (AD) is a natural biochemical process that converts organic materials into combustible biogas. It has been long practiced for agricultural and urban waste management (info 11). However, biogas production from biomass waste and its utilization for energy applications are still challenging due to the complex physical and chemical properties of organic waste, which affect the metabolic pathways and methane content (info 10).
Pro Tip: To enhance biogas production, ensure proper feedstock selection and pre – treatment. For example, chopping and grinding the biomass can improve the digestion process.
A practical example is the wastewater treatment facility located in Escondido, CA. It has an average daily flow of ~ 15.6 MGD and produces biogas at a rate of ~ 95 million cubic feet per year. This biogas contains enough energy to supply ~ 1,200 homes (info 13).
Upgrading
Upgrading biogas to RNG involves removing impurities such as carbon dioxide, water vapor, and hydrogen sulfide. This makes the gas comparable to natural gas in terms of quality and energy content. According to a SEMrush 2023 Study, upgrading can significantly increase the marketability of biogas.
Power – to – Gas
Power – to – Gas technology converts surplus electricity, often from renewable sources like wind and solar, into hydrogen or methane. This helps in storing excess energy and integrating it into the natural gas grid.
Reactor configurations
Different reactor configurations are used in biogas and RNG production, each with its own advantages and disadvantages. High – rate reactors, for example, can achieve high biogas production rates but may require more complex operation and control. As recommended by industry experts, choosing the right reactor configuration depends on factors such as feedstock characteristics, available space, and desired biogas output.
Common problems and engineering solutions in technologies
Complex organic substrate properties
The complex physical and chemical properties of organic substrates can pose challenges to the AD process. For instance, the presence of lignin in some biomass can make it difficult for microorganisms to break down the substrate. Engineering solutions may include pre – treatment methods such as enzymatic hydrolysis or steam explosion.
Over – acidification
Over – acidification can occur when the pH level in the digester drops too low, inhibiting the growth of methane – producing bacteria. To prevent this, careful monitoring of the digester’s pH and the addition of alkalizing agents can be employed.
High solid content
High solids anaerobic digestion process (HS – AD) has received attention for its benefits like water conservation and smaller digester footprints. However, the high solid content of the feedstock can lead to poor mixing and heat transfer. Strategies such as mechanical agitation can be used to improve the situation.
