Fuel of the Future: Renewable Energy from Biogas
26th April 2017 @ 7:30 pm - 9:30 pm
Biogas (or renewable natural gas) is the name for the mixture of methane and carbon dioxide (CO2) which is produced naturally when organic matter decomposes.
Biogas can be produced when food waste from households, manure, or crops from agriculture is broken down by micro-organisms in digesters and wastewater treatment plants. Biogas can be used for heating, power generation or upgrading to natural gas quality.
When upgraded to purified biomethane it has a number of desirable characteristics, compared to other established fuel energy sources, and even to most renewable energy systems, such as biofuels:
* less harmful to world ecology than traditional fossil fuels
* no impact on the food chain – in contrast to land take-up for crop-based biofuels
* more beneficial by utilising otherwise wasted materials for the methane source
* carbon negative through the capture of methane
There will always be a supply of organic waste products. In this sense, biomethane is a truly renewable natural gas.
