We understand the requirements of remote locations and environmental considerations of the South Pacific Island nations. We work with our clients to understand their needs, available resources and any other local requirements. Taking this information into account we are then able to provide guidance on the most suitable solutions available.

Bioenergy Roadmap

Many regions in the Pacific have demonstrated interest and taken steps to promote the development of bioenergy through the utilisation of bioenergy roadmaps. Hydroflux is well-versed in this process and can provide assistance in the development of such roadmaps for industrial clients.

A bioenergy roadmap serves as a strategic plan that defines the vision, goals, strategies, and actions required to foster the use of bioenergy as a sustainable and renewable energy source. It acts as a guiding document for policymakers, stakeholders, and the wider community, facilitating the advancement of bioenergy technologies and resources in terms of their development, deployment, and utilisation.

Biomethane upgrading technology has reached a mature and proven stage, with installations worldwide spanning over a decade, largely driven by our international partners. Hydroflux Pacific is ideally positioned to not only offer support during the planning stages but also implement tailored solutions through its local offices and extensive network. We possess a wide range of technologies that can be customized to meet the unique needs of individual businesses.

AAT & Hydroflux Pacific provide solutions, no matter from what source material you generate biogas.

The conversion of organic material into biogas is a convincing concept both from an economic and ecological perspective. Instead of disposing of materials at high costs or using other less lucrative recycling options, the material and energy is wholly utilised and fully converted into marketable products whilst reducing CO2 and Methane emissions.

There are a multitude of potential sources of feedstock for anaerobic digestion, such as:

  • Distilleries
  • Breweries
  • Dairy processors
  • Food processors
  • Pre-sorted municipal waste
  • Water treatments plants
  • Farm manure

AAT has designed and realised biogas facilities for over 150 different substrates where the gained biogas is converted into electricity and long-distance heating or prepared as bio-methane. The remaining digestate can also be converted into valuable fertilizer.

Sludge from primary water treatment, expired food and organic food waste, animal manure, spent grain from brewing or distilling are some examples.


An AAT, bioenergy plant handling 30000 Tons/annum of sewage sludge, 44000 Tons/annum of food waste and 11000 Tons/annum of fruit- and vegetable waste. The plant yields over 23000 m3/day of biogas producing 2.4 MW of electrical energy per day

AAT plants have been operating internationally for many years, offering successful sludge digestion solutions to large-scale farms, waste disposal companies, and the food industry. AAT is a trusted partner that collaborates with Hydroflux Pacific to provide comprehensive treatment systems and plant equipment, including modular units like waste pre-treatment and pasteurization. With our combined expertise, we deliver competent solutions for efficient and effective waste management and treatment processes in the Pacific region

Hydroflux has partnered with Baur Folien GmbH based in Germany, a market leader and specialists in the selection, design, supply, manufacture, and installation of high-quality gas storage equipment to maximise the product reliability whilst reducing the project lifecycle costs.

Gas Storage for Industry 

Double membrane gas storage systems represent the cutting-edge technology in biogas storage. These systems are highly robust and durable, capable of storing variable amounts of gas while maintaining a constant pressure.

The outer layer of the system consists of a weather protection foil, which effectively shields the integrated inner gas storage foil from wind and rain. This protective barrier ensures the longevity of the gas storage membrane, enabling it to provide extended service life. The use of high-quality materials enhances chemical resistance and minimises diffusion rates, even under higher operating pressures.

Double membrane gas storage systems can be installed on various structures, including in-situ concrete, precast, or suitable steel tanks. The flexibility of the gas storage membrane allows it to adapt to the gas production levels. Additionally, the shape and colour of the gas storage covers can be customised to meet specific requirements and customer preferences.

Biogas Blowers

Hydroflux has access to a comprehensive range of blowers, including the specialised Himmel GVD Biogas blower, designed for operation with wet biogas.

Biogas blowers, also known as gas blowers or biogas compressors, are devices specifically designed to handle the compression and movement of biogas. The primary function of biogas blowers is to increase the pressure of the biogas, allowing for its efficient transportation, storage, or utilisation. These blowers help overcome the natural low-pressure characteristics of biogas, enabling it to be effectively delivered to various downstream applications.

When selecting a biogas blower, it is essential to consider factors such as reliability, energy efficiency, and compatibility with the specific biogas composition. Hydroflux has access to a comprehensive range of blowers, including the specialised Himmel GVD Biogas blower, designed for operation with wet biogas.

Whether you need a blower for a small-scale biogas system or a larger industrial application, Hydroflux can provide the right solution. With a focus on reliability, energy efficiency, and compatibility with different biogas compositions.

Biogas Chilling (Moisture removal) and Biogas Skids (Moisture removal and gas pressure boosting)

Digester produced biogas is 100% water saturated and as it cools in the lines to the point of reuse, large amounts of water can condense in the piping system and the combustion device.

There are multiple benefits in drying biogas to a low dew point before combustion in a combined heat and power (CHP) engine or boiler. Hydroflux can incorporate the most suitable biogas cooling and collection system into the treatment process. These can be offered with or without compressors for gas pressure boosting.

Some of the benefits of working with Hydroflux to design and provide biogas chilling and moistrure removal systems include:

  • Increased engine/boiler efficiency
  • Prevention of corrosion/oil contamination
  • Partial removal of impurities such as H2S, ammonia and siloxanes
  • Complying with technical instruction of gas engine/boiler suppliers
