Renewable Energy
The technology has been designed to deliver thermal or
electrical energy outcomes in a modular format which can be scaled depending
upon the availability of feedstock and product markets. While the energy output
will be directly linked to such factors as the volume, type and moisture
content of feedstock, typical deployments will indicatively range from 0.8MWe
to 5MWe (producing electrical output of 6,400-40,000 MWh per annum).
Customers seeking renewable
energy outcomes will typically assess PacPyro against gasification, combustion
and pyrolysis technologies. Gasification
will be relevant to projects which have a large supply of clean, high grade
timber, which are seeking energy only outcomes.
Combustion technologies require a similar grade feedstock to
gasification, but are relevant for larger scale electrical generation projects
with significantly higher energy needs (e.g.
30-40MW).
Small scale combustion is also used over a range of thermal
applications, however its poor emissions profile makes planning consents very challenging.
While other technologies have their place, PacPyro’s slow
pyrolysis technology will be advantageous when dealing with:
- • Low grade feedstocks with a combination of high ash content, low ash melting points, high moisture content and varying and large particle size. This would include paper and waste water sludge’s, animal manures, municipal green waste, and agricultural crop residues;
- • Variability in feedstock supplies caused by seasonality or uncommitted feedstocks – waste management companies often deal with variations in greenwaste composition across seasons (increased woody waste from gardens versus increased grass clippings for example);
- • The need for multiple revenue streams to de-risk the project from an over-reliance on any one type of revenue (i.e. tipping fees, energy and/or biochar);
- • Low emissions profile as a key objective; and
- • Biochar production being desirable for agricultural
or horticultural uses.
