Executive Summary – Strategic Partnership Impact
Komatsu Ltd. × AFC Energy plc
Topic: Ammonia-based pathway to decarbonise diesel engines in heavy machinery
Overview
Komatsu Ltd., one of the world’s largest manufacturers of construction and mining equipment, has entered a Joint Development Agreement (JDA) with AFC Energy plc to explore the use of ammonia cracking technology as a lower-carbon alternative to conventional diesel engines.
The cooperation focuses on integrating AFC Energy’s ammonia-to-hydrogen cracking technology into industrial engine platforms, with the objective of reducing CO₂ emissions while retaining internal combustion architectures.
Strategic Rationale
For Komatsu
Provides a pragmatic, transitional decarbonisation pathway without abandoning proven diesel engine platforms.
Avoids near-term dependency on large-scale hydrogen refuelling infrastructure, which remains limited in heavy-duty and off-road applications.
Preserves capital efficiency by leveraging existing engine designs, manufacturing assets, and global service networks.
Positions Komatsu as a technology-agnostic OEM, pursuing multiple decarbonisation routes (hybrid, electric, alternative fuels).
For AFC Energy
Validates AFC Energy’s ammonia cracking technology through collaboration with a tier-one global OEM.
Represents a potential commercialisation bridge beyond stationary power and generator markets.
Strengthens credibility with investors by demonstrating applicability in large-scale industrial and mobile equipment.
Expands addressable market into construction, mining, and heavy industrial sectors.
Technology & Market Context
Ammonia (NH₃) is increasingly viewed as a practical hydrogen carrier due to:
Higher volumetric energy density than compressed hydrogen,
Established global transport and storage infrastructure,
Suitability for industrial and remote applications.
The approach under evaluation:
Uses ammonia as fuel,
Cracks it onboard or near-engine into hydrogen,
Feeds hydrogen into modified combustion engines.
This strategy contrasts with pure hydrogen fuel cells, which offer near-zero emissions but face cost, durability, and infrastructure constraints in heavy machinery.
Investment Implications
Low short-term execution risk for Komatsu: R&D-driven exploration rather than immediate product dependency.
High strategic optionality: If viable, ammonia-based engines could act as a mid-term bridge technology toward full decarbonisation.
Positive signal for AFC Energy: Reinforces its positioning as a critical enabling technology provider rather than a niche hydrogen play.
Sector relevance: Reflects a broader trend among heavy-equipment OEMs toward multi-path energy transition strategies, rather than single-technology bets.
Outlook
Short to mid-term: Feasibility studies, prototype testing, emissions validation.
Mid-term potential: Pilot deployments in selected industrial or
