AB Energy – Liquefaction of RNG

A Better Way

About the Company:

Since 1981, AB has tackled the challenges posed by energy sustainability, working alongside their customers to improve their competitiveness while saving energy and reducing emissions. From their earliest days, they have focused on innovation to develop world-class technologies and processes dedicated to transforming the world of energy.

AB’s objective is to ensure their customers benefit from the best energy sustainability solutions available anywhere.

The AB Group now boasts over 1,000 employees in 20 countries throughout Europe, Russia and North and South America, with primary production and engineering centralized in a state-of-the-art industrial complex located in Orzinuovi, Province of Brescia, Italy.

AB’s customers rely on AB to develop the “Better Way” to support them with the skills, technologies, and processes, so they perform at their best. Together, we are helping build a better world.

AB Strives to be the global reference point for energy sustainability. For AB developing innovation at the service of their customers’ energy means making businesses more sustainable, competitive, and virtuous, reducing consumption, increasing efficiency, and providing customers with advanced technologies and a high-quality service.

About the Solution:

Connection to the natural gas grid is not always possible. Liquid renewable natural gas is the solution where there are logistical constraints.

Liquefied RNG, in fact, is not only easily transportable to its point of use but, thanks to its density, three times higher than that of compressed natural gas, it ensures greater efficiency when used as fuel. The main difference between bio-CNG and bio-LNG (i.e. between compressed RNG and liquefied RNG) lies precisely in the latter’s use, mainly in heavy vehicles, where its autonomy almost doubles compared with the gaseous form, thus constituting the ideal alternative to diesel for long distances.

RNG liquefaction is a complex process, which consists in cooling and compressing the gaseous RNG at very low temperatures. The transformation is such that the liquefaction of RNG is very advantageous compared with other gases: with 600 liters of gaseous biomethane, only one liter of liquid RNG is obtained.

An AB RNG liquefaction plant is a containerized modular solution based on an integrated cryogenic process, divided into three phases: treatment, liquefaction, and storage. An efficient system that can also be combined with other AB solutions to create a totally sustainable energy system.

Advantages:

  1. Storage: Liquid RNG has an easy production and delivery programmability
  2. Flexibility: Liquid biomethane is the solution where connection to the gas network is possible. In fact, it is easily transportable with cryogenic tankers up to its point of use
  3. Efficiency: Bio-LNG is a valid alternative to diesel for heavy transport, as it guarantees greater autonomy in long-haul travel

Solution Strengths, Weaknesses and Critical Indicators

Anaerobic Digester Associated Technology:

NOTE: There are several technology types that are used as part of an integrated manure management system that includes an anaerobic digester and are not applicable to manure management in other cases. The impact of these technologies on the critical indicators are represented as those of an entire anaerobic digester system.

   

  • Long usable life and can be run reliably
  • Creates energy and generates environmental credits
  • Requires proper preparation of the feedstock
  • Requires other technologies for energy utilization
  • Requires other technologies for digestate handling
  • Proper feeding & system monitoring is required to avoid system downtime
  • Proven technology for odor control, GHG reduction and pathogen reduction
