ABOUT BIOGAS

What is Biogas & Anaerobic Digestion?


Anaerobic digestion (AD) is the breakdown of organic material by micro-organisms in the absence of oxygen. AD produces biogas, a methane-rich gas that can be used as a fuel, and digestate, a source of nutrients that can be used as a fertiliser. Increasingly AD is being used to make the most of our waste by turning it into renewable energy.



DID YOU KNOW THAT ....

Biogas is a mixture of around 60% methane, 40% carbon dioxide and traces of other contaminant gases, Biogas can be combusted to provide heat, electricity or both.


Combined Heat and Power (CHP)


Combined heat and power (CHP) is the simultaneous production of useable heat and electricity.  As the process of AD requires some heat it is suited to CHP and this is currently the most popular option for UK plants. Whilst coal and gas-fired power stations have an efficiency of around 34% and 55% respectively, CHP plants can achieve overall efficiencies in excess of 80% at the point of use.


The ratio of heat to power varies dependent on the scale and technology, but typically 35-40% is converted to electricity, 40-45% to heat and the balance lost as inefficiencies at various stages of the process.

Biolectric Micro Scale  AD Plants - How does it work?


The Biolectric biogas installation daily pumps a fixed quantity of slurry from the reactor to the digestate storage and replaces the discharged volume with fresh manure from the manure pit. This process is fully automated and is done under supervision.


 

Biogas is formed in the reactor through anaerobic fermentation. The gas is then purified and in the combustion engine it converts to to green energy. This energy can be used in the form of electricity and heat on the farm.


Biolectric systems are classed as micro   AD   because of the size of energy output i.e. 11-44kw and the benefit of installing these smaller sizes is that we can match the power usage of the farm  to gain maximum efficiency and therefore greater returns.  Larger AD plants export a great percentage of their electricity which is only worth around 50% value  and cannot use all the available heat. Matching  the size to the farms usage is not only the most efficient but is the    most environmentaly  concious  option.





On a farm with 80 cows the yearly CH₄ emission of manure is equal to the CO₂ equivalent of 110 160 kg per year.

 

By placing a Biolectric biogas installation this CH₄ (Methane) is converted into green energy and heat, enough to replace 110 cars off the road every year.

THE BENEFITS

You Invest

It Pays Off

You help

At least 1500 m³ liquid manure per year and about 200 m² space on your farm.

An award winning ready-to-use Micro AD digester with a capacity from 10 kW to 44 kW. An effortless, fully automatic mono digester creating your own green energy on the basis of your farm's slurry. You get independence from energy producers and distributors and the increasingly rising energy prices. Our installation is recouped in as little as 5 years

You create and use your own green energy. You get a fixed price per kWh of produced green energy, in the form of goverment backed FIT (feed in tariff) or  RHI (renewable heat incentive) payments for 20 years. There is a short payback period.

Because you continually create green energy. Because you no longer depend on the rising electricity prices. Because you produce warm water. Because the manure becomes more liquid. Because the manure is more quickly absorbed. Because you keep your fixed costs under control.

Because you reduce your CO₂ footprint. Because you reduce the odour. Because you keep CH₄ out of the atmosphere. Because you think about the environment. Because you think about the next generation









There are some distinct advantages to a Biolectric micro biogas plant: no more rising electricity bills, free hot water, diversification of the income of the farmer, added value of your slurry, more liquid slurrye and faster absorption of nutrients, and an fully automated slurry gas plant with patented reactor building.

Because electricity keeps getting more expensive. Because you already have the resources. Because it suits your farm. Because the sun doesn't always shine. Because the wind doesn't always blow.








There is no competition between food and energy. You have no additional noise or odours by supply of crops, surplus or waste. You get local fertilizer, local production, local consumption: there are no hidden transportation fees or emissions. The raw material, slurry, is renewable and available for free






































You are convinced of the usefulness of our micro AD plantsrand would like to place one on your farm. But you don't know what the requirements are. You will see that even the smallest farm can be enough to profit from our this new green technology. Just call us and arrange an informal appointment
