[Gasification] Abattoir's pyrolysis plant bucks methane power-making trend

Mark,

 

Shame on you for doing the math. It was probably pitched as a least cost
disposal option with the added benefit of power generation. Nutrient
management, heat and material  balances, or life cycle costs may not have
been considered. We’ll have to get Joel Arcus of BioWaste Technologies into
the conversation. With the instability of power generation in South Africa
you would think that gasifiers could compete.  

 

Just to throw a “spanner” into the works have a look at a recent Spanner
gasifier installation in the UK.

£500,000 (USD $767,000) for 90 kWe and 216 KWth. $8,500/kWe. With the right
fuel these gasifiers have a very high availability of 7,000-8,000 hours per
year. In Germany they have sold 400+ as heating devices for farms. Since the
German utilities pay something like $0.28/kWh  it helps pay off the
investment. We can’t justify the in North America. In the UK, as the article
points out, the customer is the government. You need the Renewable Heat
Incentive (RHI) and the Renewable Obligation Certificates (ROC) to justify
the investment. So when it comes to gasifiers the UK ROCS! At least this
year. 

 

It would be nice to see gasifiers pay their own way with real revenues but
fossil fuels keep a lid on that opportunity.

This is surely over-hyped, Tom. Eleven-tonnes of waste (which is likely 85%,
or more, water) implies that over 9,000 kgm of water will need to be
evaporated each day just to end up with a couple of metric tons of
pyrolyzable waste. This is beyond ludicrous! Why not simply enzymatically
digest the offal, pasteurize it, and overland apply it as a soil amendment?
HAS to be some govmint money pushing ridiculous projects like this one!
