Generate your own heat and power from wood fuel: save, earn and reduce your carbon footprint

Absolute have just launched their 50kW (electrical) combined heat and power (CHP) units. CHP units use

wood fuel to produce a gas which powers a generator, providing heat and power for your business. This

technology attracts significant incentives and helps you to reduce your bills and carbon footprint.

Benefits include:

Annual benefit of £75,000 - £100,000

3 – 6 year payback

20 – 30% ROI

Businesses are continually searching for technologies to help them improve efficiencies, save money or even earn

money and grow.

Over the past few years, the biomass industry has grown significantly. The commercial sector has embraced this

technology and has already received billions of pounds through incentives.

Until recently, most biomass systems have only produced heat. Absolute have now launched their new combined

heat and power units, which not only produce heat, but also generates electricity from the same wood fuel.

The biomass industry is now well established market in the UK and there are many biofuels companies providing

a consistent supply of quality wood fuel.

Absolute have secured partnerships to offer Froling and ESPE combined heat and power (CHP) units which use

wood fuel to generate heat and electricity.

As was biomass heating before it became popular in the UK, gasification CHP has been available across Europe for

a number of years and is a well-established technology.

Business across Scotland and the UK are installing gasification CHP units to provide heat and electricity to reduce

their bills, generate significant income from the incentives and reduce the amount of CO2 they produce.

With Carbon taxes set to be introduced in 2018 (requires verification), business owners are rushing to take

advantage of the incentives at their peak to maximise their returns, and avoid paying significant carbon tax bills in

the future.

Uses:

Heat buildings and swimming pools

Farms and rural businesses

District heating

Process heat

Dry wood chip and other bulk solids

Offset electricity usage

Power back up

Incentives:

Maximise earning through the renewable heat incentive (RHI)

Maximise savings through displacement of fossil fuels and electricity bills

Export excess electricity to the grid (Export Tariff)

Minimise carbon taxation

Gasification Combined Heat and Power

CHP units use wood chips as fuel for gasification. The fuel gas synthesis (Syngas) obtained is the fuel feeding the

micro-generation unit, which allows for the combined production of electricity and thermal energy. CHP units can

supplement or replace boilers for commercial, industrial and agricultural production cycles and produce

electricity from renewable sources.

Potential Thermal Output (@ 8,000 hours):

ESPE CHiP 50 Cogeneratoro 110 kW thermal

= 110 x 8,000= 880,000 kWh

Potential Electrical Output (@ 8,000 hours)

ESPE CHiP 50 Cogenerator (49kW & 51kW models available)o 50 kW el

= 50 x 8,000= 400,000 kWh

When the electrical load is not being used, the electricity will be exported at 4.5p per kWh. When additional loads

are required, the customer will continue to pay existing rates for electricity.

The heat generated from CHP units must be used at all times to ensure continuation of electrical output at 49 –

51kW. When this does not happen, the system will modulate to a lower output; reducing electrical output,

thermal output and resultant incentives. Using the CHP unit with a drying system to maintain the necessary

moisture content of the fuel, also serves as a heat outlet for the CHP unit, allowing the system to run

continuously.

Running Hours

With adequate on site experience and the right operation and maintenance package in place, CHP units should be

capable of running for 8,000 hours.

It is advised that excess heat is used for maintaining W10 chip for the CHP unit and electricity can be exported to

the grid, rather than using the CHP unit on an on/off basis.

Chip Drying & Fuel Feed

The required moisture content for CHP units is 10%. It is essential for CHP units to run on 10% moisture content

(M10/10MC) fuel only. Failure to do this will reduce the performance and efficiency of the unit and result in

additional maintenance of the unit for the customer.

Servicing, Maintenance & Warrantee

CHP units require daily checks and inspections (circa 20 min). A full list of maintenance requirements are available

upon request.

Indicative annual servicing costs of £8,000 - £12,000 are advised, which includes a reservoir fund for an engine

replacement.

The standard warrantee on the system is one year for parts, two years for the installation. Details for extended

warrantee products will be available autumn 2015.

Return on Investment

The ideal site would be a high energy user. The unit is capable of generating in excess of 400,000 kWh electrical

output and 900,000 kW thermal output, so a user of this magnitude would realise the most benefit.

Examples

High user spending £22,000 on mains gas per annum. Using 75% of the electrical load on site, exporting 25% to

the grid.

The above table is for guide purposes only.

Medium user spending £10,000 on mains gas per annum, using 50% of the electrical load on site, exporting 50%

to the grid.

The above table is for guide purposes only.

Low user spending nothing on heat currently, using 25% of the electrical load on site, exporting 75% to the

grid.
