Battery storage & inverters
What is battery storage?
Battery storage and inverters are critical in enhancing biogas’s effectiveness as a renewable energy source. Because biogas generation can vary with changes in feedstock availability and digestion processes, implementing reliable energy storage solutions becomes essential. These components ensure a stable and consistent energy output, allowing biogas systems to meet demand even during fluctuations. Practical storage solutions help maximise biogas utility, supporting renewable energy goals and promoting energy resilience.

Consistent and cost efficient power supply
Battery storage systems capture excess energy produced during peak biogas production. Facilities can use this stored energy during periods of low output or increased demand. Integrating battery storage enhances energy reliability and helps facilities optimize energy usage, reducing dependence on external energy sources. By storing surplus energy, facilities can improve operational efficiency, lower costs, and enhance the sustainability of their biogas systems, making renewable energy sources more practical and effective.

Battery type options
Lithium-ion batteries are more widespread for their efficiency, long lifespan, and capacity to handle frequent charge and discharge cycles. They are generally lightweight and compact, making them ideal for applications where performance and portability are essential. Their high energy density and versatility make lithium-ion batteries a common preference across various applications.
Lead-acid batteries are typically more affordable than lithium-ion batteries but have a shorter lifespan and lower energy density. They are also heavier and bulkier, which can limit their use in weight-sensitive applications. However, they perform well in high-power applications and are often more resilient in extreme temperatures. Lead-acid batteries are chosen for situations where cost and robustness are prioritized over weight and energy efficiency.

Inverters
Inverter equipment plays a pivotal role in this setup by converting the direct current (DC) generated from the biogas system into alternating current (AC), which is required for most applications and the electrical grid. Advanced inverters also offer smart grid functionalities, enabling biogas systems to interact dynamically with the grid, manage energy flow, and provide grid services such as frequency regulation. This capability not only enhances the value of biogas energy but also contributes to grid stability.
The combination of battery storage and inverter technology allows for greater flexibility in energy management. Facilities can take advantage of time-of-use electricity rates, discharging stored energy during peak pricing periods while charging during off-peak times. This strategic approach can lead to significant cost savings and improve the overall economics of biogas
