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 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 […]
How to Make Biogas: From Organic Waste to Renewable Gas
Biogas is made when microorganisms break down biodegradable organic material in the absence of oxygen. The controlled process is called anaerobic digestion, and it can convert food waste, animal manure, sewage sludge, crop residues and many other organic materials into a useful renewable gas. The principle sounds simple: place biodegradable material in an airtight digester […]
What Is Biomethane? How It’s Made, Used and Why It’s Renewable
Biomethane is purified biogas that can replace fossil natural gas in compatible pipelines, boilers, industrial processes and vehicles. Discover how it is made, why its environmental performance depends on feedstocks and methane control, and where this renewable gas is most useful.
Biogas Digester: How It Works, Types and Uses
A biogas digester is a sealed reactor in which microorganisms break down organic material without oxygen. This process, called anaerobic digestion, produces biogas and a remaining material called digestate. “Methane digester” is another name people use for a biogas-producing anaerobic digester: methane is the energy-rich component of the gas, rather than a different digestion process. […]
Methane Facts and Why It’s a Greenhouse Gas Much Worse than Carbon Dioxide
Climate Clarity: What You Need to Know About Methane and Global Warming Methane is the second-largest driver of global warming after CO2, responsible for roughly 30% of the temperature rise since the Industrial Revolution. Molecule for molecule, methane traps heat 86 times more powerfully than carbon dioxide over a 20-year period — making every emission […]
Biogas Production Process Steps: From Feedstock to Usable Biogas
The biogas production process converts biodegradable organic material into a methane-rich gas that can be used as a renewable source of energy. But there is an important distinction that is often missed when the process is explained. The four stages commonly described as the “4 stages of biogas production” — hydrolysis, acidogenesis, acetogenesis and methanogenesis […]
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 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, […]
The Future of Biogas: From Niche Technology to Global Climate Solution
Introduction: The Future of Biogas Has Arrived For most of its history, biogas has existed quietly on the margins of the energy debate. A useful technology, certainly — but one that struggled to command the same attention as solar panels or wind turbines. That era is over. In 2026, as the World Biogas Association (WBA) […]
Creating Safer Working Environments in Waste-to-Energy Facilities
For operators and professionals across the anaerobic digestion (AD) and waste-to-energy (WtE) sectors, it is easy to view modern processing plants as highly engineered, controlled environments distinct from traditional waste handling. However, safety in WtE facilities in the UK is poor in comparison with other industries, and recent safety performance data serves as a stark […]
