At Helec we have extensive experience with both domestic and commercial Biomass CHP technology .

Helec have many years’ experience with a variety of Combined Heat & Power solutions through a multitude of fuel sources and the recent Government incentives to drive down emissions and look for low carbon heating solutions has prompted Helec to source a partnering Biomass CHP manufacturer.

The core product for biomass CHP systems is the:

ESPE CHiP50 Biomass Combined Heat & Power Gasification unit (110kW/th & 50kW/e)The ESPE “CHiP50”

Particle size of wood chips: P 50 main fraction 3.15mm < P < 50mm, min 80%; fine fraction < 1mm, max 5%; thick fraction >50mm, max 1%.

How the CHiP50 System Works

Biomass Combined heat & Power unit uses virgin wood chips as a fuel source in the gasification of a solid material which in turn produces a gas (Syngas) which is the primary fuel used to run the motor engine which turns the alternator and produces the 50kWe electricity at source.The thermal energy created in the gasification and electricity generation process provides a combined value of 110kW/th which heats the systems cooling water circuits and this is transferred away via a plate heat exchanger which is connected to a thermal store and makes available hot water for space heating systems and domestic hot water pre-heat & production.

Funding schemes, incentives and grants

There is no direct funding or grants available for CHP. There are, however, a number of Government funded incentives to help recoup the capital and running costs, these include:

• exemption from the Climate Change Levy for all Good Quality CHP fuel inputs and electricity outputs

• eligibility for Enhanced Capital Allowances (ECAs) for Good Quality CHP plant and machinery

• business rates exemptions for certain Good Quality CHP schemes• enhanced eligibility for Renewables Obligation Certificates (ROCs) for renewable CHP schemes

• eligibility for ROCs for the biomass element of fuel used in biomass or energy from waste CHP plants

• reduced VAT on the installation of micro-CHP

• eligibility for the Renewable Heat Incentive as of June 2011, where a qualifying renewable fuel source is used

Government funded schemes change year by year so please sense check and verify first with either your local government web site or the governments national web site

How Biomass Systems Work

Biomass consists of any animal and vegetable derived biological material in non-fossil form from which energy can be obtained. The European Union considers the energy application of wood biomass one of the most effective systems for reducing greenhouse gas emissions (see European Directive 2009/28/EC for references and guidance). The combustion of wood in fact releases the same amount of CO² that a tree absorbed from the atmosphere during the course of its growth.The balance regarding CO² therefore stays level. What’s more, if the wood should not be used and simply left to degrade and rot in the undergrowth the same amount of CO² would be released into the atmosphere. Therefore, it makes good sense to exploit energy derived from natural wood waste.
