Biomass energy is one of the most sustainable and renewable sources of energy on the planet: there will always be biological waste from processes involving wood, livestock farming and crops, and biomass energy is a way to ensure these waste products can be put to good use.

These natural materials can be converted to fuel pellets, which in turn provide heat and power to be used in both domestic and commercial applications.

Biomass energy: top facts

Biomass energy is carbon-neutral – while carbon dioxide is released when biomass fuels are burned, its source material took carbon out of the atmosphere when it was growing.

Biomass fuels can be sourced locally so they’re good for long-term energy security – there’s no reliance on energy sources outside the UK.

Using biomass fuels means you’re helping to support the UK’s rural economy.

The main sources of biomass fuels are trees, energy crops, agriculture and industrial waste.

Biomass fuels can be used to power stoves, boilers and anaerobic digesters, ranging from small units designed to heat a room through to highly sophisticated boilers that can supply hot water to an entire housing development.

Energy problems biomass fuels can help solve

It is widely thought that biomass fuels can be a huge part of the answer to many energy problems facing the UK (and the world more widely), including the following:

Energy security

Currently much of the oil and gas the UK relies on comes from overseas and often has to be transported through countries with whom diplomatic relations may be fragile. Using biomass fuels would reduce this reliance on other countries because all the resources needed to create the fuel pellets are available here in the UK.

Carbon emissions

Fossil fuels such as oil and coal provide a huge amount of the UK’s power, but they also pollute the atmosphere and contribute to climate change by releasing large amounts of carbon. Biomass fuels are carbon-neutral, meaning they don’t damage the environment.

Sustainability and renewability

There will always be forestry and agriculture in the UK, and therefore there will always be the waste products of these processes. This means the creation of biomass fuels has the potential to be truly sustainable in the long term, unlike fossil fuels which will one day run out.

Installing biomass energy

In order to get started with biomass energy, you’ll need to think about the kind of system you want. These are the main kinds of biomass system available and what they’re used for:


Biomass stove

for heating a room


Biomass boiler

for heating water, both for hot water supply and a building’s central heating system.


Biomass anaerobic digester:

to process sewage to create fertiliser or methane gas for energy.

We can help you work out the most appropriate system for your requirements.

Powering a biomass energy system

One of the most popular ways to power a biomass system is using biomass pellets. For large users, such as commercial premises, lorries can deliver the pellets directly into a store at the property. Meanwhile, if you’re using biomass pellets to heat your home, you can buy bags of biomass pellets containing between 10 and 25kg of fuel.

The high energy density of biomass pellets means that you’ll need less storage space than if you use other fuels such as logs or coal.
