Modular LNG Systems We Build
The HRU Advantage
A&R Solutions supports the deployment of Hybrid Refrigeration Units (HRUs) — a next-generation approach to modular LNG liquefaction. HRUs provide mobile, scalable, off-grid LNG production, engineered for rapid installation and high-reliability performance in environments where traditional infrastructure is limited or disrupted.
These systems are designed to help utilities, industrial operators, and regional planners stabilize supply, enhance resiliency, and reduce operational constraints across the energy chain.

1-acre operational footprint
Modular by design
Expands up to 1M+ gal/day
Source-agnostic fuel intake
No grid connection required
$12–15M estimated CAPEX
$2–3/MMBTU operating costs
Energy & Power
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged

FUEL PATHWAYS WE SUPPORT
Hydrogen & Methane Energy Pathways
A&R Solutions supports multiple hydrogen and methane fuel pathways within an evolving energy landscape. Drawing on our expertise in modular LNG systems, cryogenic engineering, and fuel-agnostic infrastructure, we help enable solutions that balance performance, emissions considerations, regulatory requirements, and real-world deployment conditions.
Blue Hydrogen
Hydrogen produced from natural gas using carbon capture technologies to reduce lifecycle emissions. Blue hydrogen provides a transitional pathway that leverages existing gas infrastructure while supporting lower-carbon power and industrial applications.
Green Hydrogen
Hydrogen generated through electrolysis powered by renewable electricity sources such as wind or solar. Green hydrogen offers a low-emissions option for long-term decarbonization, energy storage, and clean power integration.
Green Methane (Renewable Methane)
Methane produced from renewable or biogenic sources and fully compatible with existing natural gas infrastructure. Green methane enables reduced-emissions operation without requiring major changes to storage, transport, or combustion systems.
Gray Methane (Conventional Natural Gas)
Conventional methane remains a critical energy source for reliable power and thermal applications. When paired with high-efficiency systems and optimized fuel management, it continues to support mission-critical operations while serving as a baseline for transition planning.
