Energy

Renewable and clean energy programsprogrammes, engineered and assured for the transition.

Operating domains

Two domains, one accountable standard.

Electric vertical take-off aircraft in flight

Clean

01 · Low-Carbon and Nuclear

Clean

What we doWe assure the technologies carrying the energy transition forward. We certify and qualify battery-electric and hydrogen powertrains, new propulsion and battery systems across aviation and heavy transport, and we bring nuclear-grade safety and regulatory support backed by our ISO 19443 certification. We de-risk these programsprogrammes. We do not build or operate them.

Renewable

02 · Wind, Solar and Grid

Renewable

What we doWe help owners and developers bring renewable programsprogrammes safely into service across wind, solar, and the grid connection and storage that link them. For offshore wind we add marine operations safety and governance aligned to the regulator, backed by systems and design engineering, safety and quality assurance, programprogramme controls and field delivery.

Selected engagements

Who we worked with, what we did, and the difference it made.

Fortescue battery-electric haul truck operating at a mine site.

Fortescue Zero

01 · Clean

Qualifying battery power for Fortescue Zero's electric haul fleet

What we didWe supported Fortescue Zero as it scaled battery-electric haul trucks on the T264 platform, where unproven technology, global supply chains and rigorous battery qualification created high delivery and assurance risk. We helped the programprogramme qualify a high-power battery system under real mining conditions.

High-power battery system qualified under real mining conditions.
Confidence strengthened to progress design and production decisions.
Confidence built to accelerate decarbonisation of the heavy haul fleet.

H55 battery modules for electric aircraft propulsion.

H55

02 · Clean

Certifying H55's battery-electric powertrain for the BRM Energic

What we didWe supported H55 in certifying a battery-electric powertrain for the BRM Energic aircraft, balancing rapid innovation against strict regulatory compliance on a fast-moving certification timeline. Our work helped integrate new technologies safely while maintaining assurance across architecture, safety and configuration.

Certification-ready system designs achieved for the battery-electric powertrain.
Regulatory alignment strengthened, enabling confident progression toward aircraft certification.
New technologies integrated safely, with assurance maintained across architecture, safety and configuration.

Marine operations governance for Salem Offshore Wind

What we didWe developed the Marine Operations Safety Manual and Administration Manual for the Salem Offshore Wind project. Working with Crowley Wind Services, we reviewed how the business manages marine projects against regulatory requirements and stakeholder expectations, then turned that review into clear, regulator-aligned operational guidance.

Clear, regulator-aligned operational guidance delivered for marine projects.
Exposure to schedule and budget risk reduced.
Executive confidence in marine project governance strengthened, with lower reputational and commercial risk.
