Bioenergy

This study assesses the suitability of various-sized wood-fired boilers for providing some or all of the Brewery's process steam needs.

It also assesses the possibility of using an absorption chiller to provide some or all of the sites cooling requirements using wood energy. Three boiler scenarios are considered. The two most attractive scenarios are described in detail, both delivering an IRR of 7 - 8%.

East Harbour Energy was commissioned by Fonterra to carry out an assessment of the feasibility of converting the energy supply at their Tuamarina, Kaikoura, and Culverden milk processing plants from diesel or LFO to wood fuel.

This report investigates the site requirements, the regional wood fuel supply, suitable boiler plant, consenting issues, risks, benefits, and provides a financial assessment of conversion.

This report, "Wood energy supply options for City Forests Limited (CFL)" addresses the requirements of the supply chain, from forest floor to point of sale. From a forest owner's perspective it is important to understand the security of demand for the woody bioenergy product, the cost of production of the product, and any barriers that may limit the potential of this new business stream.

On behalf of the Greater Wellington Regional Council (GWRC) the New Zealand Clean Energy Centre (NZCEC) has investigated the harvesting residues available in GWRC forests for use as a commercial energy product. NZCEC has carried out studies to investigate volumes of residue available, a viable extraction method, and added value drying techniques across three seasons for the residues.
