MICRO CHP PRODUCTS http://www.microchap.info/

Micro CHP (Combined Heat & Power) is the simultaneous production of useful heat andpower within the home. It works very much like the gas boiler in a central heatingsystem and heats the home in just the same way. However, at the same time itgenerates electricity, some of which you will use in your own home; the remainder isexported to the grid to be used by your neighbours.

Natural gas is consumed in an engine (or other prime mover) to provide heat andelectricity for use within the home. In the case of engine-based micro CHP a total ofaround 70-80% of the energy value of the gas is converted into heat, principally in theform of hot water which is used for space heating and domestic hot water production asin a normal central heating system. Between 10-25% is converted into electricity, andthe remainder (5-15%) is lost in the flue gases.For fuel cell based systems, the electrical efficiency tends to be significantly higher, insome cases more than 40%, but the total efficiency is roughly the same.This compares with a conventional gas central heating boiler where around 90% of theenergy in the gas is converted into heat and the remaining 10% is lost in the flue gases.

Although the total "efficiency" of a micro CHP system is similar to a boiler system, theelectricity produced has a much higher value than heat. It is the value of this electricity

which covers the investment cost of the micro CHP unit and provides a net saving.This section is intended for those who are considering the purchase of a micro CHP system, either for their own home or for c lients. Although technical details aregenerally available from the links to suppliers' web sites, specifiers and other professionals may wish to consult thePaperssection to gain a better understandingof the wider issues surrounding micro CHP. Products which are available on a commercial basis are clearly identified as such in their descriptions and contain alink to the supplier. Before considering the purchase of a micro CHP system, however, you should consult theEconomicssection, or undertake some othereconomic viability assessment, to see whether your investment is reasonable.Information on enabling technologies, which enhance the value of micro CHP, is also included.EXTERNAL COMBUSTION

hence does useful work.

As the combustion process is used toprovide a continuous heat input to the

working gas, it is more controllableand generally more efficient, cleanerand quieter than internal combustion

engines.

External combustion engines havethe potential for long life and service

intervals similar to the annualmaintenance of a gas boiler.

However, the inherent benefits of thistechnology have yet to be fully

realised. Both Stirling and Rankineengines have suffered from reliabilityproblems, and have failed to deliver

the promised efficiencies.

Early mini CHP products were derivedfrom automotive engines converted torun on Natural Gas and suffered fromvery high service costs and unreliable

operation.

Current models, however, have beenspecifically developed for extended

operation between services. Contraryto expectations, the inherent technical

challenges of ICE technology arebeing gradually overcome and current

engines outperform externalcombustion engines significantly in

EXTERNAL COMBUSTION TECHNOLOGYThe first true micro CHP systems were based on external combustion technology as their characteristics are best suited to this stationary, constant runningapplication. External combustion engines separate the combustion process (which is the energy input to the engine) from the working gas, which undergoespressure fluctuations and hence does useful work. As the combustion process is used to provide a continuous heat input to the working gas, it is inherently morecontrollable and, in theory at least, more efficient, cleaner and quieter than internal combustion engines.The two most common external combustion micro CHP technologies are the Stirling engine, in which a working gas is alternately heated and cooled to createpressure changes which in turn drive a power piston, and the Rankine engine in which a fluid is heated to evaporate and expand against a piston or turbine, andthen cooled and condensed prior to the next heating and cooling cycle.For further discussion of the relative merits of engine types see section on papers; greater detail and description of operating principles can be found in the book,

STIRLING CYCLEThere are two principal types of Stirling Engine, kinematic and free-piston. All Stirling engines have two pistons (functionally speaking), one of which shuttles theworking gas between the hot and cold zones and is known as a displacer, whilst the other is subject to the resulting pressure changes and does work to drive theengine. In the kinematic engine, these two pistons are physically connected by a crank mechanism, whereas in the free-piston engine, there is no physical linkageand the displacer oscillates resonantly. In theory the LFPSE (Linear Free Piston Stirling Engine) is much simpler as it contains fewer moving parts. In practice,the challenges of differential expansion and linear generator design have so far proved a major obstacle to commercialisation.

Despite expectations of product availability as recently as late 2012, the decision by E.ON to abandon a fully proven product as it no longer fittedtheir core strategy, may have been the final nail in the coffin for this technology, particularly given developments in fuel cell based micro CHP

technologies.WhisperGen MEC (Microgen) Infinia (STC) Disenco (Inspirit)

The WhisperGen micro CHP unit comprises afour cylinder engine which leads to smooth, lowvibration operation, with noise levels similar to a

domestic freezer.

In January 2008, WhisperGen announced theestablishment of a joint venture (EHE) with

Spanish white goods manufacturer MondragonCC to mass produce units for the European

market.

Several hundred units underwent extensive fieldtrials in Europe and technical issues appeared

to have been fully resolved.

E.ON announced forthcoming product launch inNovember 2012, then just prior to actually doing

so, decided to "focus on core business",whatever that means.

EHE is now in receivership and there seemslittle prospect of that technology becoming

commercially available in the foreseeable future.

The Microgen unit, developed by BG Groupfrom a US (Sunpower) design, is a LFPSE

which is intended for wall-mounting; it contains asupplementary burner which enables it to meet

the full heating requirements for even largerhomes.

Following disposal by BG Group in 2007,development of the Microgen unit was taken

over by MEC, a consortium of gas boilercompanies (Viessmann, Baxi, Vaillant, Remeha)

and Sunpower.

Each of the boiler companies has developedtheir own variant of micro CHP unit

incorporating the MEC engine, now beingmanufactured in China.

The UK variant is manufactured by Baxi, part ofthe BDR Thermea Group which also includes

Remeha, De Dietrich and Brtje.

The Infinia (formerly known as STC) LFPSEwas developed for incorporation in micro CHP

products manufactured by Ariston (formerlyMTS) and Bosch in Europe as well as Rinnai in

Japan.

Rinnai will also produce the LFPSE module forintegration into micro CHP packages by the

other partners for the European market, with atrial of 1000 units planned for 2008-2010.

Although based on a virtually identical coreLFPSE as the MEC derivatives, this unit is more

realistically housed within an integrated floor-

mounted unit incorporating a hot water cylinder.The Infinia engine previously formed the basisof the ENATEC micro CHP unit, a joint venture

between the Dutch utility ENECO, ECN andappliance manufacturer ATAG.

As of 2013, there has still been no commerciallaunch and it is believed that development has

been abandoned.

The Disenco unit is a kinematic design with anelectrical output of around 3kWe, significantly

higher than the other products.

In January 2008, Disenco announced amanufacturing partnership with Autocraft toproduce the core engine, with packaging by

Malvern boilers and recently announcedmarketing deals with Endesa and Centrica.

In early 2010 Disenco was placed inreceivership; the design has been taken over by

Inspirit Energy who expect to trial the unit in2011.

In 2013, Inspirit still seem to be facing fundingdifficulties and no product availability has been

announced.

RANKINE CYCLE

The Rankine cycle, like the Stirling cycle is an external combustion cycle; the combustion process is external to the cylinder containing the working gas. TheRankine cycle is characterised by the working gas undergoing a phase change (from liquid to gas) which can be utilised to achieve high power densities. Themost familiar Rankine engine is the steam engine in which water is boiled by an external heat source, expands and exerts pressure on a piston or turbine rotor andhence does useful work.

A number of the products below make use of this concept. However, one of them (the Energetix Genlec) is an organic Rankine engine which uses an organic fluid(a refrigerant) and operates at temperatures and pressures much closer to conventional heating and refrigeration appliances. This has the significant advantage ofallowing the use of conventional, mass produced components and eliminates many of the technical challenges of steam engines. However, the relatively lowtemperature differential between hot and cold stages of the cycle, limit the Carnot (theoretical) efficiency; in practice efficiencies in single digits are commonplace.For further discussion of the relative merits of these engine types see section onpapers.

GENLEC CLIMATE ENERGY OTAG ENGINION COGEN MICROThe Energetix Genlec unit, is currently the

only truly wall-mounted micro CHPanywhere in the world.

In effect, it is a refrigeration unit working inreverse, using the expanding working gasto power a scroll expander (compressor).

In theory, the ORC (Organic RankineCycle) design can be constructed usingoff the shelf components for the majority

of the appliance, leading to low production

costs. However, this product now makesuse of bespoke components intended to

optimise the performance.

It's relatively low electrical efficiencymeans that it produces less electricity fora given heat load than some other units,although this should be compensated for

by the expected low cost.

In 2012, Energetix established an energysupply company, Flow Energy, whichoffers a package including gas and

electricity supply as well as the microCHP unit. In July 2013, having gained40,000 customers, the energy supply

company ceased customer acquisitionactivities to focus on product

commercialisation.

The Climate Energy unit also uses ascroll expander, with benefits of

simplicity and potentially lowmanufacturing cost.

However, the use of steam as aworking gas raises technical

challenges regarding reliability andsafety. Against this, the developers

claim that the thermodynamic

properties of steam permit high heattransfer rates (resulting in compactheat exchangers), tolerate leakage

and have no inherent materialrisks. It is also non-toxic and

thermally stable which, combinedwith the zero cost make this a

competitive technology.

Climate Energy LLC have alsolaunched the Honda ICE based unitin the USA and it is uncertain as to

whether they intend to continuedevelopment of their external

combustion unit.

Illustration shows the Honda Ecowillunit.

Otag have developed a steampowered unit, utilising a single

cylinder with two opposingpistons. An integral linear generator

converts the reciprocating motiondirectly into electrical energy withvariable output 3 phase output.

Further details including an excellentanimation of the cycle are shown on

the Otag website.

Although originally intended to bewood-pellet fired, the unit is currentlyavailable in Germany as a gas-fired

product only.

The company website provides anillustration of the economic benefits,including tax rebates, which deliver

a net benefit of around 1000annually.

The product has been branded the"Lion Powerblock".

The Enginion Steamcell unit wasinitially developed as a small

commercial unit with a power outputof around 50kWe. It then evolvedinto a unit more appropriate forsmall apartments and hotels; the

target power output of ~5kWe madeit unsuitable for domestic

installations.

Enginion was placed in receivershipduring late 2005.

The Cogen Micro unit, developed byan engineering consultancy

(Applidyne) in Australia is unusual inthat it uses reciprocating (single

piston) technology.

Historically the very low efficienciesachievable at reasonable

temperatures and pressures havenot been attractive.

However, novel injector design hasenhanced the performance of

prototype units which may lead to anultimately viable product.

In 2011 Cogen Micro appear to haveabandoned this novel design in

favour of an Organic Rankine Cycledesign similar to that from Energetix,the principle difference being that a

reciprocating rather than scrollexpander is used.

INTERNAL COMBUSTION TECHNOLOGYInternal Combustion Engines offer significant advantages over external combustion in many applications, particularly automotive where there is a need for rapidvariation in power output, which can be achieved by changing the fuel supply rate.However, for continuous operation with extended service intervals, as required for domestic heating systems, the challenges facing ICE are formidable; untilrecently it was considered that the cost of the components required to achieve the appropriate emissions reduction, sound attenuation, efficiency and reliabilityparameters would be excessive. Early products, based on automotive ICE technology, operated with some success in niche applications, but were unable toovercome these technical challenges and were beset with high service and operating costs.The products mentioned below, however, have primarily been developed for long life with relatively low service intervention and incorporate a range of featuresaimed at achieving the performance desirable for domestic and small commercial applications. They are divided into three nominal power ranges, 1kWe, 5kWeand 10kWe matching applications including typical family homes, guest houses and commercial buildings respectively.

Family Homes (1kWe) Guest Houses (5kWe) Commercial (10kWe) Commercial (100kWe)

FAMILY HOMES 1Kwe ClassWith electrical outputs around 1kWe and thermal outputs around 3kWt, these products are suited to homes with an annual thermal demand of around 20,000kWh,typical for family homes in most North European countries. Generally with electrical efficiencies of around 25%, the relatively low heat output (compared withStirling engines) means that, if properly controlled, they will operate for several thousand hours annually, greatly enhancing their electricity production and thus

shortening payback times.However, the need to incorporate an additional heat source for periods of high peak thermal demand, means that it is very important to ensure the engine iscontrolled so as to maximise its operating hours, otherwise the potential benefits of higher electrical output can be lost.

ECOWILL 1.0kWe VAILLANT 1.0kWe PROENVIS 2.0kWe KIRSCH 1.9kWeHondas 1kWe cogeneration unit was the worlds firstpractical micro CHP unit for home use; the majority of

installations globally (i.e. those in Japan) are external tothe home. The incorporation of catalytic converters andan elaborate acoustic attenuation system, together with

novel engine design, have overcome the principlelimitations of ICE design, namely noise, emissions and

service intervals.

However, the inclusion of these additional components

results in a very high installed cost, which is difficult tojustify on economic grounds. In the Japanese market,high electricity prices and capital grants greatly improve

the economic viability for the end user.

With nearing 100,000 units installed in Japan since2003, the Ecowill is now being marketed by Climate

Energy in the USA.

Launched onto the German market in early2011, also based on the successful Honda

ICE. Similar in performance to the Ecowill, butdiffering in significant respects:

1) It is suitable for indoor installation, althoughrather bulky when account is taken of the

numerous additional components required tocomplete the installation.

2) It has a slightly higher electrical and overallefficiency (26% & 92% LCV respectively),

compared with an overall efficiency of 85% forthe Ecowill.

Not surprisingly this enhanced performancecomes at a price, more than double that of the

Japanese product!

The Proenvis prio 5.2,(presumably indicating its nominal

thermal and electrical outputsrespectively) and designated by its

manufacturer as "nano-CHP" isanother German ICE based micro

CHP product. It is capable ofmodulating its electrical output

between 1.3-2.0kWe.

At the same time it producesbetween 3.0-5.5kWt of heat withan overall efficiency of 93%, 25%

electrical and 68% thermal.

The floor-mounted product is66x66x115cm with a weight of

185kg.

Kirsch have developed a range of small CHPsystems with electrical outputs up to 50kW. Kirsch

nano, the smallest is based on Briggs & Stratton ICEtechnology with a power output of 1.9kWe.

However, with an electrical efficiency of only 19%and thermal output of 9kWt, it is unlikely to achieve

significant running hours in any but the largest familyhomes, so that payback will be challenging. It is

configured to run in thermally led mode.

Evidence of an "off the shelf" engine rather than abespoke micro CHP design, is clear from the servicerequirement every 2,500 hours and a major overhaulat 20,000 hours. It is of course also apparent from

the efficiency, well below its competitors.

It is currently only available in Germany.
