What is biomass?

   Solid plant matter (that
    can be used as fuel)
       Wood (logs, forestry
        arisings, manufacturing/
        construction waste)
       Straw (from oil seed rape,
        wheat)
       Dedicated crops (short
        rotation coppice,
        miscanthus)
Why biomass?




   Carbon neutral fuel
Why biomass?
   Legislation
       Zero carbon new
        buildings – 2016, 2019
       EU renewable energy
        targets
       Climate change bill
       Climate change levy
       Energy Performance
        Certificates
Why biomass?
   Cost of fuel and landfill charges
Why biomass?

   Local economy
       Farm diversification
       Local jobs
       Sustainable energy
        supply
Applications
   Room heaters/stoves
       Suitable for most homes on or
        off gas network as secondary
        heating
       Attractive room feature
       Link to hot water system and
        possibly radiators
       Pellet stoves can be
        automatically controlled and fed
       Grants available for
        householders
        Applications
   Boilers
       More suited to larger homes
        and buildings where mains gas
        is not available
       Need space for boiler and fuel
        storage
       Can supply large peaks in
        demand – e.g. historic buildings
       Grants available for
        householders and communities
       Interest free loans available for
        SMEs
    Applications
   District heating and combined heat
    and power
       Communal supply of heat and
        electricity
       Neighbourhood scale
       Need diverse heat demand
       Possible option for eco-towns or
        existing urban/suburban environments
       Renewables Obligation Certificates
        can be earned and sold
       Feed in tariff for electricity?
    Applications
   Power stations
       Very large utility scale
       Dedicated type: e.g. 38MW
        straw-fired plant in Ely
       Co-firing biomass in existing coal
        fired power stations
       Heat is wasted due to remote
        locations
       Renewables Obligation
        Certificates can be earned and
        sold
Potential market?

   Straw – enough in Uttlesford to supply heat
    needs of all oil and coal heated households
    two and half times over
   Emergence of ‘anchor’ users offers
    opportunity for local supply network to be
    established
   Operations with their own supply of low cost
    biomass material best placed to become
    fuel suppliers
