Anaerobic Digestion and Biogas News and Developments
Biogas Storage: Gas Holders, Tanks, Bags and Storage Methods
Biogas storage provides a buffer between continuous gas production and the sometimes variable demand for that gas. Anaerobic digesters normally produce biogas around the clock, while CHP engines, boilers, upgrading plants and other gas users may shut down, operate at reduced load or experience periods of higher and lower demand. For that reason, almost every […]
Biogas Upgrading Technologies: How Biogas Is Upgraded to Biomethane
Which biogas upgrading technology is best for producing biomethane? This guide compares membrane separation, water scrubbing, PSA, amine systems and other technologies, including methane recovery, pretreatment, methane slip, cost drivers and gas-grid injection.
Biogas pH Control Equipment: Monitoring, Alkalinity and Dosing for Anaerobic Digesters
Biogas pH control involves much more than measuring pH and adding alkali. Learn how digester pH probes, alkalinity, VFAs, FOS/TAC and dosing equipment work together to identify and prevent anaerobic digestion process instability
Biogas Generator Manufacturers: How to Compare Gas Engine and CHP Suppliers
Choosing between biogas generator manufacturers is not simply a matter of comparing the number of kilowatts printed on competing quotations. A generator set that looks excellent on a datasheet can become expensive very quickly if it is poorly matched to the available biogas, difficult to service locally, sensitive to contaminants or routinely operated well below […]
Biogas Engines and Generators: How They Turn Biogas into Electricity
We have defined what we mean by a biogas engine and how such engines are used as a biogas generator, including discussing what cogeneration means in terms of secondary heat ultilisation and CHP
Biogas Heating Systems: Boilers, Direct Heat and When They Beat CHP
A biogas heating system can be one of the simplest and most efficient ways to use the gas produced by an anaerobic digestion plant. Instead of converting the biogas into electricity first, the gas is burned in a suitable boiler or process heater and its energy is used directly as heat. That option is sometimes […]
Biogas CHP Systems: Benefits, Efficiency, Costs and Design
Biogas CHP systems transform waste into power, achieving efficiencies over 80%. Ideal for on-site energy, they lower bills and carbon emissions. Agricultural producers, wastewater plants, and landfill operators benefit, despite the high upfront capital costs, by turning waste into reliable energy sources for sustainable operations…
Biogas Utilisation: CHP, Biomethane, Heat and the Best Uses for Biogas
Biogas utilization thrives on combining heat and power units for maximum efficiency. With energy efficiencies reaching up to 90%, CHP systems are a game-changer in waste management and renewable energy production, offering energy independence and diverse revenue streams for agricultural and municipal operations alike…
Anaerobic Digestion Heat Exchangers: Types, Uses, Fouling and Heat Recovery
Anaerobic digestion heat exchangers perform one of the less glamorous but most important jobs on a biogas plant: moving heat from where it is available to where the process actually needs it. They can heat incoming feedstock, maintain digester temperature, recover heat from hot digestate, transfer heat from CHP engines, provide energy for pasteurisation and, […]
Biogas CHP Design: 7 Factors for Selecting and Sizing a CHP System
Biogas CHP design involves much more than selecting a gas engine with an electrical output that appears to match the expected biogas production from an anaerobic digestion plant. A successful combined heat and power (CHP) installation must match the quantity and quality of the available biogas, the site’s electrical demand, the genuinely useful heat demand, […]
Do Home Biogas Digesters Really Work? Costs, Gas Output, Safety and Common Myths
Do home biogas digesters work? Yes. A correctly sized and well-operated home biogas digester can turn food scraps or animal manure into useful cooking gas and nutrient-containing digestate. However, these systems do not produce unlimited free energy; they are not equally effective in every climate, and they require appropriate installation, feeding and maintenance. If you […]
How to Increase Biogas Production – 8 Ways to Improve Biogas Yield from AD Processes
Learning how to increase biogas production is not simply a matter of feeding more organic material into an anaerobic digester. Sustainable improvement comes from stabilising the biological process, selecting compatible feedstocks, maintaining effective mixing and using operating data to identify the true cause of lost methane yield. This updated guide explains eight practical areas that […]
