Gero,

 

Questions for you and other gasifier suppliers:

 

1. What is the current population of your operating gasifiers? From the 17
(including Gustaf’s) sold at about one / year, 7 of the later ones are still
in operation, but this will hopefully change drastically once my comments in
7. (below) materialize. 

2. Specifically, where are they? 3 in Japan, 3 in South Africa and 1 Demo
unit in Namibia.

3. What fuels do they use? Wood blocks (mainly Eucalyptus Camaldulensis and
African invader bush) and briquetted sawdust / agricultural waste.

4. What is their peak operating capacity? (kWe/kWhth) Depending on Gasifier
type, our currently biggest unit (450Nm³/h) has an output of 255kWe (with a
turbocharged Genset) and 684kWth.

5. At what capacity are they typically operated? (KWe/KWhth) As per 4.

6. What is their typical capacity factor (operating hours per year at full
load equivalent(kWe)/8760 hours) The users run one to two shifts/day, but
the design allows 24/7 operation at max load.

7. What new projects are in the pipeline? We have a number of exciting
projects in the pipeline in South Africa, but our national utility (Eskom)
and NERSA (national energy regulator) are dragging their heals in
promulgating feed-in tariffs. This has been going on for two years, but
there is light at the end of the tunnel and investors are getting ready to
finally climb on board. Or, where is the industry headed? Our Government has
reaffirmed its commitment to go for and support RE (renewable energy)
projects. More small scale? Yes, in our RE field, up to 2 to 3MWe, and large
scale for wind, hydro, solar and other RE technologies like PV. 

Mini-grid? Yes, for rural off grid community upliftment. Higher capacity? A
mix of min 1MWe up to multi MWe for feeding into the national grid.

Our “playing field” is in all those categories by paralleling our 450Nm³/h
(255kWe) units from 0.5MWe to max 3MWe. We are limiting plants to 3MWe for
feedstock logistics reasons --- thumb rule is 1kg biomass = 1kWe, meaning
that the hourly consumption of 3tons (72tons/24hrs) is currently a
self-imposed limit in our local feedstock scenario.  

 

Thanks,

Tom

Hi Tom,

 

I have also been corresponding with Pawel regarding our System Johansson
Gasproducers.

Herewith an update for you: Attached is the self-explanatory accolade for
2010 from Frost & Sullivan, UK.

 

Kind regards,

Pawel

Community Power makes a CHP 100 kW unit, see www.gocpc.com.

All Power Labs, Jim Mason, (Berkeley) makes a 10 kW power supply.  The heat
would be easy to add.
