This means that, for the same volume, natural gas has a much higher energy density than wood pellets. For example, the price of wood pellets ranges from 150 to 350 euros per ton, while the price of natural gas depends on the specific region and supply situation. Generally, wood pellets are usually cheaper than natural gas.
During use, natural gas is cleaner and produces less pollution. Compared to wood pellet fuel, burning natural gas doesn't create a lot of ash or harmful gases, which helps reduce air pollution. However, wood pellets are renewable and more widely available, helping cut down dependence on fossil fuels. When it comes to resource use, biomass wood pellets are a sustainable energy option, while natural gas relies on fossil fuel extraction, which is limited and can cause environmental damage during the process.
Taken together, biomass wood pellet fuel and natural gas each have advantages and disadvantages. Natural gas has obvious advantages in calorific value, combustion efficiency and cleanliness, but it is expensive and may have certain environmental impacts during extraction and transportation. Wood pellet fuel has more advantages in terms of cost and renewability, but is relatively low in terms of combustion efficiency and environmental impact. The choice of fuel depends on the specific application and needs.
