Fuels with ecologically favourable side-effects
Sewage gas, landfill gas and biogas are fermentation gases that are classed as specialty gases, and are increasingly referred to as "green gas". These high-energy gases occur as a result of fermentation, i.e. the anaerobic, microbial degradation of organic matter. Base materials can include sewage sludge, biodegradable waste, but also agricultural materials such as slurry and manure or purpose-grown energy crops.
The energy-carrying component of fermentation gases is the climate-relevant gas methane, with a proportion of 40-85 percent. If this gas mixture which is similar to natural gas is used to produce electricity and/or heat, CO2 emissions and energy costs can be reduced considerably.
Extraction, preparation and use of biogenic gases
Energy extraction from fermentation gases has many economical and ecological advantages, and a variety of system variants are used including combined heat and power (CHP) units, fuel cells, Stirling engines and micro-gas turbines. KLT-Consult has many years of experience in production, processing and use of sewage and landfill gases, but we have also already implemented biogas plants.
A particular focus is on solutions for more flexible gas storage and greater energy efficiency of gas-powered heat and power co-generation units, as well as energy management systems which reduce peak demand of electricity and gas and which optimise the use of gas, particularly in relation to security of supply. In planning, optimisation, construction and operation, it goes without saying that our main focus is always on cost-effectiveness, safety and industrial safety.
