What is green gas?
Green gas is a sustainable alternative to natural gas. It's produced from organic waste streams such as manure, vegetable and fruit waste, and other natural materials. By upgrading this gas, it achieves the same quality as natural gas and can be used directly in the existing gas network.
How is green gas made?
Green gas is produced using two methods: fermentation and gasification. During fermentation, wet organic waste streams, such as manure and vegetable and fruit waste, are converted into biogas by bacteria in an airtight tank. This biogas is then purified into green gas.
Green gas can also be produced by gasifying dry biomass. Both processes yield a combustible gas that, after purification, has the same energy value as natural gas and can be used directly in households and industries.
What is the difference between green gas and natural gas?
Natural gas, also known as gray gas, is extracted from fossil fuels and contributes to greenhouse gas emissions. Green gas, on the other hand, is renewable and produces significantly lower CO2 emissions, making it a more sustainable alternative.
What is the difference between green gas and biogas?
Although both are derived from organic materials, biogas is an unprocessed form that is not yet suitable as a replacement for natural gas. Green gas is purified and upgraded biogas, giving it the same quality and properties as natural gas and allowing it to be seamlessly fed into the existing gas network.
Benefits of green gas for the environment
One of the biggest advantages of green gas is the reduction in CO2 emissions. The CO2 released during combustion is already absorbed by the biofuels used. This means almost no additional CO2 is added to the atmosphere.
In addition, green gas production contributes to a circular economy. Organic waste, such as manure and fruit and vegetable scraps, is reused as an energy source instead of being discarded. This reduces dependence on fossil fuels and minimizes waste.
Another advantage is that digestate, a by-product of green gas, contains valuable minerals that can be used as fertilizer in agriculture.
The role of green gas in the energy transition
According to the Climate agreement, the Netherlands must transition entirely to sustainable energy sources by 2050. Green gas plays a key role in this, as it utilizes existing infrastructure and can serve as a direct alternative to natural gas.
A major advantage is that households and businesses don't need to modify their systems to use green gas. Moreover, green gas is produced locally, making the Netherlands less dependent on energy imports.
The future of green gas in the Netherlands
Green gas is a vital link in the transition to sustainable energy. It offers an environmentally friendly alternative to natural gas and contributes to a circular economy. Because it can be used directly in existing infrastructure, the transition to a more sustainable energy system is easier and more affordable.
