As specialists in complex engineering and emerging technologies, we work with companies building the next generation of energy systems and propulsion solutions. From hydrogen fuel cells and battery management systems to EV infrastructure and regional electrification strategies, we help organisations articulate their role in the energy transition and convert that into tangible business value.

This is our approach to purposeful PR — building profile not as an end in itself, but as a means to support investment, partnerships, policy engagement and pipeline growth.
 

Hydrogen technology companies (Production, storage, distribution, combustion and fuel cells

We support companies developing hydrogen technologies across the value chain from production and storage to fuel cell applications, helping translate complex engineering into clear, investible and partner-ready narratives. Read about our work building investment raise propositions and road show materials for a leading hydrogen fuel cell company.

• Communicating technical propositions to non-specialist audiences across multiple channel
• Building grant funding & investment profile through targeted communication with identified decision-makers
• B2B trade media PR, thought-leadership scripting

Synthetic and e-fuels (Drop-in, bio, power-to-liquid and power-to-gas)

We work with companies developing synthetic and alternative fuels to position their role within the broader energy transition, particularly where technologies intersect with existing infrastructure and regulatory frameworks.

• Articulating the role of alternative fuels within net zero strategies in opinion-forming editorial
• Supporting stakeholder engagement across policy, industry and media with clear and focused read-ins, policy papers and speech writing
• Building engaging narrative to find audiences for complex production processes and applications

Energy carriers and infrastructure (Ammonia, methanol, LOHCs, carbon capture, hydrogen & CO₂, pipelines)

We support companies developing the infrastructure and carrier systems that enable energy transition at scale, helping them articulate both technical capability and strategic importance. Read how we set out a manifesto commitment for one national charge point operator to align their customers, landowners and investors in a single, unified proposition.

• Positioning infrastructure in national and global energy strategies
• Delivering communications strategies to reach end-user customers and build market influence
• Lobbying Whitehall with compelling advocacy for appropriate tax and subsidiary consideration

Renewables and bio fuels (Wind, solar, hydro, geothermal, biomass and waste-to-fuel)

We work with companies across renewable and biofuel technologies to position their solutions within integrated energy systems, particularly where multiple technologies and markets intersect. We have recently managed a campaign promoting green hydrogen electrolysis as a solution to curtailment. Our capabilities include:

• Communicating system-level value and integration in thought-leadership contexts
• Supporting project announcements and strategic partnerships with trade and national press
• Building visibility in competitive and policy-driven markets through earned media and paid digital channels

See how we shaped Intelligent Energy’s recent raise by building a differentiated investor narrative.

Launches, GTM and strategy

We’ve press-launched everything from Formula 1 cars to world-beating grid-storage battery management systems

See how GroupWhistle defined an electrification cluster strategy for a former battery gigafactory site.

How does GroupWhistle make complex tech readily comprehendible for the press, analysts and investors?

We act as translators, with the capacity to interpret engineering and apply an editorial assessment of what aspects are required to build an engaging narrative for non-specialists.

We use our in-house studio capabilities to support words with clear graphics, animations and other explainer media.
 

How do we build pipeline?

We place trade media stories to provide you with third party product or service validation and authority.

As it is unlikely that your customer-to-be will read this story at the right time, we distribute this editorial content via customer job title and company targeting using paid LinkedIn and subsequently industry reads delivered via email marketing. We call this PR+.
 

For what time period does GroupWhistle provide services?

The most cost effective approach is a retainer agreement which provides a blend of different skills from our team, often at a lower cost than an extra person on your payroll.

For ad hoc needs, for instance when your team needs support with a major event, or a fixed term project such as an investment raise, we work on a fixed scope, time period and fee.
 

If you’re looking to cut through the noise in the clean energy sector, we can help your technologies and services stand out with GroupWhistle’s services all tailored to help you transact, whether raising funding, going to market, protecting market position or growing market share.

Our senior strategy team would love to know more about your business and provide some preliminary ideas to enable your mission. No prep needed, no obligation. If you’re curious to understand how PR can help, give GroupWhistle a call.
