Methodology
AMS-II.H.
Also known as: Energy efficiency measures through centralization of utility provisions of an industrial facility
TL;DR
CDM small-scale methodology for industrial energy-efficiency improvements via centralisation of utility provision — niche but used by a handful of Indonesian palm-oil refining projects.
Full explainer
AMS-II.H. is a niche CDM small-scale methodology for industrial energy-efficiency improvements achieved by centralising the provision of utility services (steam, electricity, compressed air) across a multi-process industrial facility. The methodology credits the heat-recovery and load-consolidation gains from replacing distributed boilers and pumps with a single utility plant.
A small number of Indonesian palm-oil refining and pulp-and-paper projects have used AMS-II.H. The methodology overlaps with biogas methodologies for POME (AMS-III.H. covers methane recovery from biogenic waste streams, which can be the energy source for a centralised utility). Both are part of the small-scale CDM portfolio closing to new registrations as the CDM winds down post-2024.
