Global biogas and RNG industry leaders are always finding new ways to optimize their efficiency and raise their revenues. Some are using digital solutions to help raise energy output, while others are relying on new installation strategies to maximize yield. Most solutions, however, come down to mere chemistry. With the right nutrients, temperatures, biogas digester,and hydraulic retention time, you can increase production at an affordable price. Let’s explore your options.
The Power of Additives
Many optimization methods in the biogas industry require expensive equipment investments. That pushes them beyond the realm of your average business, but additives can improve your yield at a considerably lower price. Carbon-encapsulated iron nanoparticles can:
- Improve methane production
- Reduce the cost of production
- Eliminate almost all hydrogen sulfide gas, thereby improving the lifespan of cogeneration engines
- Improve the stability of the production process to raise quality and quantity
There are several ways to approach additives. Biological products can improve the diversity of your microbial content, raising methanogenic activity while breaking down compounds more effectively. Carbon cloth’s conductivity can improve electron transfer between different species, and carbon-based accelerants can improve the environment for microorganisms. Trace metals like nickel and cobalt can improve the metabolism of methanogenesis microorganisms. Every solution has its own unique effects.
Optimizing with the Right Substrate
Your choice of substrate determines the nutrients available during biogas production, but its temperature is equally influential. With the right carbon-to-nitrogen ratio, you can raise bacterial growth and reduce the risk of acidification. Your substrate concentration and inoculants are an affordable yet effective way to improve your results.
Choosing the Right Digester
Biogas digesters can include carbon cloth and nano-graphite, both of which can digest oily materials and food waste. With the help of a pretreatment, you can improve the breakdown of lignocellulose. The right substrate-to-inoculum ratio can also improve biogas yield exponentially. Ammonia increases pH levels, inhibiting digestion. Merely choosing the right digestate pH level can have a potent effect on efficiency.
The Role of Floating Covers
Floating covers play a core role in collecting biogas from digestate. They can reduce odors, act as a collection cover, and store gas. Membranes, domes, concrete protections, and geomembranes all have their own unique benefits and purposes. Geomembranes rely on reinforced, virtually impermeable barriers to store and control both fluids and gases. With the right biogas digester at your side, you can help pave the way to a greener future.
