9 common skill gaps in green hydrogen (and how to close them)

Green hydrogen projects are moving from vision to reality, but many are stalling not because of technology, but because of people and capabilities.

Below are nine critical skill gaps that routinely slow projects down, plus practical, talent-focused ways to close them.

1. End‑to‑end hydrogen project development

Key gaps: 

• Limited experience building bankable business cases for hydrogen, including levelised cost, incentives, and offtake risk. 
• Weak integration between renewables, electrolyser sizing, storage, and downstream demand. 
• Scarce talent with a track record of bringing hydrogen projects to FID. 

• Build a core project development team that blends power, gas, and industrials backgrounds. For example, project development managers from wind/solar plus process engineers from refining. 
• Partner with recruitment specialists who already support hydrogen developers globally to identify project development managers, commercial directors, and senior engineers with hydrogen or adjacent experience. 
• Use secondments and internal mobility: move high‑performing staff from large renewables projects into early‑stage hydrogen roles, supported by mentoring.

2. Electrolyser and process engineering expertise 

• Process engineers who understand water electrolysis, gas handling, compression, and integration with variable renewable power. 
• Electrolyser manufacturing and assembly specialists who are able to scale production lines.
• Technicians trained specifically as green hydrogen plant operators and maintainers.​

• Define priority technical roles (for example, process engineer, electrolysis specialist, plant technician) and build targeted skilling programs around them with vocational providers and universities. 
• Leverage transferable skills from petrochemicals, refining, and industrial gases; many of these professionals already understand high‑pressure systems, gas purity, and continuous processes. 
• Work with workforce partners who can map global electrolysis talent and support relocation, visas, and mobilisation to project locations. 

3. Safety, HSE and hydrogen‑specific risk management

Hydrogen is light, diffuse, and highly flammable, and its safety profile is not identical to natural gas. Many projects still rely on generic HSE frameworks that don’t fully address hydrogen’s specific risks. 

Key gaps: 

• Hydrogen‑specific safety training (leaks, embrittlement, ignition sources, confined spaces). 

• Technicians and supervisors without GWO‑style safety qualifications or equivalent site training. 

• Limited experience in integrating functional safety, emergency response, and process safety at large hydrogen sites. 

How to close them: 

• Make foundational safety modules mandatory for everyone on hydrogen sites: fire awareness, first-aid, manual handling, and working at heights, drawing on established GWO Basic Safety Training where appropriate.​ 

• Upskill HSE professionals from oil and gas and chemicals, who already understand major accident hazard regimes, and supplement with hydrogen‑specific courses and simulations. 

• Partner with specialised recruitment providers to source HSE leads, QHSE engineers, and inspectors with renewable and hydrogen exposure for critical phases such as construction and commissioning.  

4. Grid, renewables and system integration 

• Electrical and grid engineers who can design and operate renewable‑to‑electrolyser systems, including substations, interconnections, and storage. 
• Control systems and digital skills for real‑time optimisation of power flows, production, and offtake. 
• Experience aligning multiple contractors across civil, electrical, mechanical, and IT scopes. 

• Build multidisciplinary engineering squads that combine renewable power engineers, process engineers, and control engineers to design integrated solutions from the outset. 
• Invest in digital skills – data analytics, SCADA, EMS, and forecasting – to optimise utilisation and reduce energy costs. 
• Use external partners who have staffed large wind, solar, and offshore projects and can redeploy experienced grid, HV, and project engineers into hydrogen roles.

5. Permitting, environmental and stakeholder management 

Many green hydrogen projects are slowed down by permitting and community risk, not technology risk. Skills in environmental approvals, landowner engagement, and ESG reporting are often thinly spread. 

Key gaps: 

• Environmental permitting specialists familiar with hydrogen, water use, and cumulative impacts. 

• Stakeholder and land access professionals with experience aligning communities, indigenous groups, and industrial offtakers. 

• ESG and sustainability professionals who can translate complex project data into credible disclosures. 

How to close them: 

• Prioritise hiring environmental permitting and sustainability specialists as core members of the project team, not as late‑stage add‑ons. 

• Transition professionals from mining, utilities, and infrastructure sectors who already understand impact assessments and regulatory engagement, and provide hydrogen‑specific training. 

• Use talent partners with a track record in offshore wind, large‑scale solar and transmission projects, where stakeholder and environmental complexity are similar. 

6. Project management, controls and execution 

Green hydrogen facilities are capital‑intensive, multi‑contractor, and schedule‑sensitive. A lack of experienced project managers and controllers can lead to overruns and investor skepticism. 

Key gaps: 

• Project managers and project engineers used to coordinating large EPC packages under tight timelines. 

• Project controls and cost engineering professionals used to manage budgets, risk, and change in a volatile supply chain.

• Construction and offshore/onshore installation specialists comfortable working in new geographies and regulatory environments.

How to close them: 

• Source project managers, project engineers, and project controls professionals from offshore wind, LNG, and large oil and gas projects; their experience coordinating complex, multi‑partner builds is directly relevant. 
• Embed robust project controls from day one (scheduling, cost tracking, and risk management) and staff these functions with experienced hires rather than junior support.
• Work with workforce partners who can quickly scale project teams at key phases, drawing on global pools of project management and construction talent.

7. Operations, maintenance and reliability 

Once commissioned, green hydrogen plants must run safely, efficiently, and reliably for decades. Many projects invest heavily in development and construction, but underinvest in O&M planning and skills. 

Key gaps: 

• Plant technicians trained for hydrogen operations, including start‑up, shut‑down, troubleshooting, and routine maintenance.​ 

• Reliability engineers and asset managers versed in electrolysers, compression, and storage systems. 

• Spare parts, warehousing, and logistics skills to support remote or offshore locations.

How to close them: 

• Develop structured training pathways for plant technicians and shift supervisors, building on existing vocational programs for process, mechanical, and electrical trades. 

• Recruit reliability engineers from industrial gases, refineries, and petrochemical facilities; their understanding of uptime, integrity, and predictive maintenance is highly transferable. 

• Use workforce solutions providers who can support long‑term O&M staffing, not just construction, ensuring consistency across the project lifecycle.

8. Commercial, offtake and market skills 

Green hydrogen business models depend on matching long‑term offtake with policy incentives and evolving customer needs. Many projects lack commercial teams who understand both energy markets and industrial decarbonisation. 

Key gaps: 

• Business development and sales professionals who can structure offtake agreements with steel, chemicals, transport, and power customers. 

• Commercial directors and product managers who understand pricing, subsidies, and risk allocation in hydrogen value chains. 

• People who can bridge policy, finance, and technical considerations in conversations with investors and governments. 

How to close them: 

• Hire business development managers, project development managers, and commercial directors with experience in renewables PPAs, gas supply contracts, or industrial sales, and support them with hydrogen‑specific training. 

• Build cross‑functional commercial squads that include finance, policy, technical, and ESG expertise to evaluate opportunities and negotiate contracts more effectively. 

• Tap into global networks of commercial talent in emerging markets (for example, Australia, the US, the Middle East) where hydrogen strategies and hubs are already progressing. 

9. Workforce strategy, mobility and “green skills” culture 

Even with the right roles identified, many organisations lack a coherent workforce strategy for hydrogen. Competition for talent is intense across all green technologies, and companies that treat hydrogen hiring as “business as usual” will struggle. 

Key gaps: 

• Strategic workforce planning that looks across geographies, project phases, and the full hydrogen value chain. 

• HR, mobility, and payroll capabilities for moving specialised talent quickly into new markets and projects.

• A culture that values upskilling, transferable skills, and internal career mobility into hydrogen roles. 
  

How to close them: 

• Develop a dedicated hydrogen workforce plan that aligns with your project pipeline, identifying which roles to build in‑house, which to retrain, and which to source externally.

• Leverage global workforce partners with established offices, immigration expertise, and payroll solutions across key hydrogen regions, enabling faster mobilisation and compliance. 

• Invest in continuous learning: in‑house academies, partnerships with training providers, and clear pathways for oil and gas, mining, and utilities professionals to transition into green roles.

Turning skills gaps into a competitive advantage  

Green hydrogen will only scale at the pace of its people. Organisations that treat skills as a strategic asset, combining global recruitment, smart mobility, and serious upskilling, will move faster from pilots to bankable, operating assets and be better positioned to capture the long‑term value of the hydrogen economy.
