Part 2: Requirments for mCHP

European Directives Provisions, to be implemented in national legislation for

safety Essential safety requirements + scope Only products fulfilling the essential requirements may

be placed on the market

Manufacturers are free to choose any technical solution that provides compliance

Harmonized standards to show compliance (use voluntary)

European Product standards draft Fuel cell heating appliance standard mCHP standard to be developed (Cogen Europe &

CEN/CENELEC)

Requirements for mCHP (2)

Applicable European directives Gas Appliance Directive Electromagnetic Compatibility

Directive Low Voltage Directive Machinery Directive Pressure Equipment Directive Boiler Efficiency Directive Eco-design Directive (from 2010)

Above directives are to ensure safe and energy efficient products

© Kiwa 2005 8

Requirements for mCHP (3)

Related European directives Cogeneration Directive Energy Performance Building Directive Energie-efficiency en Services Directive

Above directives are to stimulate and encourage member states the efficient use of energy using cogeneration and other techniques

Requirements for mCHP (4)

Introducing Quality labels National oriented Voluntary in use Informing about and assuring

quality/performance aspects Can set requirements regarding

performance, quality and environment Safety requirements not allowed

© Kiwa 2005 10

Requirements for mCHP (5)

European examples Germany

RAL–UZ 108 Small scale Gas Fired Cogeneration Modules (der blaue engel)

- Scope is engine powered cogeneration up to 30 kWe output- Emissions requirements for NOx and CO- Full load and part load (50%) testing- Required minimum overall efficiency 87%

The NetherlandsGaskeur CV-HRe: 2007 - appliances with a nominal gas input up to 70 kW and an electrical output up to and including 2 kW

- Only for space heating (DHW under development)- Minimum efficiency 125% - Full load and part load (20%) testing

HRe

Requirements for mCHP (6)

European examples UK

PAS 67 Laboratory tests to determine the heating and electrical performance of heat-led micro-cogeneration packages primarily intended for heating dwellings

- Intention is energy performance report for mCHP to calculate annual mCHP energy performance (no minimum efficiencies provided)

- Scope is max 70 kW thermal output

- Full load and part load (10% and 30%) testing

The Netherlands Easy connect (draft idea for a future label)

- To guarantee high quality power delivering- To create easy acceptance by utilities- Testing effect of multiple systems on the grid

Requirements for mCHP (7)

(National) installation requirements Interconnection with fuel system/grid Interconnection with electricity grid

- UK => G83- Germany => VDE 0126 (ENS)- prEN 50438

Flue system design Environmental related emissions; mainly NOx

Part 3: Introducing Dutch mCHP HRe label

History Developed by Smart Power Foundation (SPF) and

provided to Dutch EPK

Scope CE marked mCHP appliances mCHP electrical output less then 2 kWe Power/heat ratio minimum 0.1 Testing quality and efficiency Space heating

Part 3: Introducing Dutch mCHP HRe label (2)

Intention Connection with Gaskeur boiler performance quality

label To outperform condensing boilers (max 110%

efficiency) Connection to the European Cogeneration Directive

(2004/8/EC)

Disadvantage (similar to boilers) Measured efficiencies not directly related to the

annual energy performance Current data difficult to be used in national EPBD

legislation

HRe

Introducing Dutch mCHP HRe label (3)

HRe efficiency shall be minimum 125% Efficiency is the average of full load and part load (20%)

efficiency Electricity produced calculated back energy savings

using Dutch reference for national power efficiency production (45,6%)

Example Energy input (natural gas) ► 100 units Heat output ► 90 units Net power output ► 15 units Calculated energy savings at national energy power

production ► 15/0.456=33 units HRe efficiency ► 90 / (100-33) = 134%

Introducing Dutch mCHP HRe label (5)

Primary Energy Saving (PES) value minimum 20% Overall PES is the average of full load and part load (20%)

PES The mCHP power and heat efficiency are compared to

European reference efficiency for stand alone heating and power production

Example Energy input (natural gas) ► 100 units Heat output ► 90 units Heat efficiency ► 90/100=90% Net power output ► 15 units Power efficiency ► 15/100=15% Reference efficiencies ► 90% (heat) & 45,6% (power) PES value ► 25%

Introducing Dutch mCHP HRe label (7)

Conclusions HRe efficiency thermodynamically not correct Fair comparison to boiler efficiencies under

EPK Understandable for Dutch consumers familiar

with boiler labels Ready for market

Future work Implementation in Eco-design Directive Setup an European test procedure providing

parameters to easily adopt in national EPBD programs
