Biogas Key Factors for Business Growth

Biogas Upgrading, Performance & Customer Service as Key Factors for Business Growth

By SYSADVANCE

SYSADVANCE, a leader in gas separation technologies, is playing a pivotal role in the production of biomethane by delivering reliable, efficient, and scalable biogas upgrading solutions. Founded in Portugal and backed by over 23 years of experience, the company now operates in more than 50 countries, applying its proprietary PSA (Pressure Swing Adsorption) technology across a wide range of industries—including biomethane upgrading, hydrogen and helium purification, as well as oxygen & nitrogen production.

To date, SYSADVANCE contributes to producing over 2.3 TWh of renewable energy per year across 48 sites, showcasing the company’s significant contribution to decarbonization and the global energy transition.

Performance and Customer Service

What sets SYSADVANCE apart in a competitive market is its strong commitment to two critical pillars: performance and customer service. The establishment of a local presence in Riga has enabled the deployment of local resources to support customers more closely, driving business growth both in the Baltic region and in neighbouring countries.

After successfully installing the first biomethane upgrading plant injecting into the Latvian pipeline in 2023, SYSADVANCE Central Europe delivered three plants in 2024, and is currently building three more, scheduled to be commissioned in 2025, bringing the total installed capacity to 415 GWh per year.

With proprietary PSA (Pressure Swing Adsorption) technology, SYSADVANCE systems ensure the highest methane recovery, low energy consumption, and consistent gas quality that meets grid injection or vehicle fuel standards. The modular design allows flexibility in deployment, whether for agricultural, industrial, or municipal waste biogas projects. This dual focus—technical excellence and client-centric service has fueled SYSADVANCE’s rapid global expansion and today the company is a trusted provider with a growing footprint across Europe, North America, and emerging biogas markets.

SYSADVANCE Technology

METHAGEN, SYSADVANCE’s range of upgrading solutions, purifies biogas from different organic sources as well as landfill gas. Systems are designed and built to reach the highest performance requirements in the biogas upgrading industry, profiting from the PSA’s ability to reduce contaminants like O2 and N2.

The METHAGEN AD series has models ranging in size from 165 Nm3/h to 3000 Nm3/h; all with a turn-down of 50% without any loss of electrical efficiency.

The METHAGEN LF series also offers a range of standardized models, delivering the highest methane recovery, combined with a very competitive OPEX.
