Energy storage is the sector where ambition and reality collide most visibly. The IEA projects a tenfold increase in global battery storage capacity by 2030, from 85 GW to 853 GW. BNEF forecasts 92 GW of new deployments in 2025 alone — a 23% jump over 2024. The IEA's World Energy Employment report recorded nearly 800,000 new jobs in EV manufacturing and batteries in a single year (2024), while the European battery supply chain already supports around 62,000 jobs with projections of 200,000–300,000 as gigafactories scale up. Yet Europe's flagship battery startup, Northvolt, filed for bankruptcy in early 2025. ACC, the Stellantis-Mercedes-TotalEnergies joint venture, shelved two of its three planned gigafactories in February 2026. The sector is hiring aggressively and restructuring simultaneously — which makes understanding the landscape essential for anyone considering a career in it.
Three industries under one label
Energy storage is not one sector. It is at least three, each with distinct workplaces, skills, and career trajectories.
Battery manufacturing
The factory floor. Gigafactories producing lithium-ion batteries for EVs and stationary storage are the most capital-intensive and employment-heavy segment. CATL's Erfurt plant employs roughly 1,700 people in Thuringia; its Hungarian facility in Debrecen is expected to reach 9,000 at full capacity. Verkor opened its first 16 GWh gigafactory in Dunkirk in December 2025, creating 1,200 direct and 3,000 indirect jobs. PowerCo (Volkswagen) produced its first cells in Salzgitter the same month, targeting 5,000 employees at that site alone. These are shift-based manufacturing environments — clean rooms, dry rooms, electrode coating lines, cell assembly, and quality testing. The work has more in common with semiconductor fabrication than with building solar farms.
Grid-scale battery storage (BESS)
The construction site and control room. Battery energy storage systems — shipping-container-sized units packed with battery modules, inverters, and cooling systems — are being deployed at an extraordinary pace. Europe installed 12 GW of energy storage in 2024, a 35% increase. Italy has overtaken Germany and the UK as the largest European battery storage market. In the US, battery storage accounted for 81% of new generating capacity in 2024. Australia has 8.7 GW of large-scale batteries under construction. BESS projects need civil engineers, electrical engineers, commissioning technicians, and — once operational — dispatch and trading specialists who optimise revenue by responding to grid price signals in real time.
Pumped hydro storage
The civil engineering megaproject. Pumped hydro remains the world's largest form of energy storage by installed capacity, and construction is accelerating — 8.4 GW of new pumped storage was added globally in 2024, nearly double the historical average. China alone added 7.75 GW. The global development pipeline stands at 600 GW. These are multi-year, multi-billion-euro infrastructure projects employing thousands of construction workers, tunnel engineers, and turbine specialists. Switzerland's Nant de Drance — a 900 MW plant built inside the Alps — took 14 years and CHF 2 billion to complete.
Where the growth is — and where it isn't
The global picture is dominated by three markets: China (61% of global battery storage deployments), the United States (27%), and Europe (a growing but still smaller share). Within Europe, the landscape is shifting fast.
Italy emerged as Europe's largest battery storage market in 2024, driven by front-of-meter grid-scale installations. Germany added 6.57 GWh in 2025, reaching a cumulative 24 GWh — but its gigafactory ambitions have been hit by slower-than-expected EV adoption. The UK installed 2.9 GWh in 2024, constrained by grid connection backlogs, though major BESS projects like Zenobe's 200 MW Blackhillock site in Scotland are coming online. European energy storage capacity is on track to pass 100 GW and could quintuple by 2030.
Hungary has become a surprising battery manufacturing hub. Samsung SDI and SK On together employed over 8,000 people in the country by end of 2024, though combined headcount has since contracted by around 2,300 as the EV slowdown hit. CATL's Debrecen factory, expected to start production in early 2026, will be the single largest battery plant in Europe at 100 GWh.
France is placing a bet on sovereign battery production. Verkor's Dunkirk gigafactory and ACC's Douvrin plant represent significant state-backed investments, though ACC's abandonment of its German and Italian sites in February 2026 shows the limits of industrial policy when market conditions shift.
The Nordics tell a cautionary tale. Northvolt's collapse — from $5.8 billion in debt to bankruptcy in early 2025, shrinking from 5,000 to around 1,700 employees — has sobered the European battery industry. FREYR Battery in Norway halted cell production and pivoted to the US to access Inflation Reduction Act subsidies. The lesson for job seekers: employer stability matters as much as sector growth.
Australia is emerging as a major BESS market, with AUD 12.7 billion in clean energy investment in 2024 — the country's largest ever — and 38 utility-scale BESS projects under construction.
The technology landscape shaping careers
Understanding the technology mix matters for career planning, because different storage technologies require different skills.
Lithium-ion dominates — 96% of installed battery storage globally uses lithium-ion chemistry, primarily lithium iron phosphate (LFP) for grid applications and nickel-manganese-cobalt (NMC) for EVs. This is where the vast majority of manufacturing and engineering jobs are.
Flow batteries — vanadium redox, zinc-bromine, and iron-air chemistries — are gaining traction for long-duration storage (4–12 hours). They require chemical engineering expertise distinct from lithium-ion, and the workforce is still small but growing.
Sodium-ion batteries are entering commercial production, led by CATL and BYD. Lower cost and no lithium dependency make them attractive for grid storage, and manufacturing processes overlap significantly with lithium-ion — meaning existing battery technicians can transition with relatively little retraining.
Power electronics — the inverters, converters, and control systems that interface between batteries and the grid — are a critical bottleneck. Every BESS project and every gigafactory needs power electronics engineers, and the talent pool is thin. This is consistently one of the highest-paid and hardest-to-fill specialisations in the sector.
Software and optimisation increasingly differentiate storage operators. BESS revenue depends on algorithmic trading — buying electricity when prices are low, selling when they spike — and the engineers who build and maintain these dispatch algorithms (often called energy traders or storage optimisation engineers) sit at the intersection of power systems, data science, and commercial strategy.
Careers across the value chain
Battery manufacturing roles
Cell engineers / electrochemists develop and optimise battery cell chemistry — electrode formulations, electrolyte compositions, cell formats. This is R&D-intensive work, typically requiring a PhD or strong Master's in chemistry, materials engineering, or chemical engineering. Cell engineers at gigafactories work on improving yield rates, energy density, and cycle life.
Battery test engineers design and execute test protocols — cycling cells through charge-discharge regimes, measuring capacity fade, running safety abuse tests (nail penetration, thermal runaway). This is laboratory-based work that requires patience and precision. A Bachelor's or Master's in electrical engineering or physics is typical.
Manufacturing technicians / production operators run the coating, stacking, electrolyte filling, and formation lines. This is shift-based factory work — 12-hour rotations are common — requiring manual dexterity, cleanroom discipline, and increasingly, familiarity with automation systems. Entry requirements are modest: vocational training or an industrial apprenticeship is usually sufficient, with on-the-job training bridging the gap. AESC's Sunderland gigafactory starts production operators at £24,896, rising to £27,259 after one year, plus 12–30% shift allowances.
Quality engineers manage statistical process control, incoming material inspection, and defect analysis. Battery manufacturing has tight tolerances — a misaligned electrode or moisture contamination can cause cells to fail or, in extreme cases, catch fire. Quality roles require a strong grasp of manufacturing processes and data analysis.
BESS project roles
BESS project engineers design and specify storage systems — sizing batteries and inverters to meet grid requirements, modelling degradation, and managing electrical design. They work with developers, equipment vendors, and grid operators through the development and construction phases.
Commissioning engineers bring BESS projects online — testing protection relays, verifying inverter-grid synchronisation, running performance tests. This is hands-on, site-based work that requires both electrical engineering knowledge and practical troubleshooting skills. Commissioning engineers travel frequently and command premium day rates.
Grid integration engineers manage the interface between storage assets and the transmission or distribution network. They handle connection applications, protection studies, and compliance with grid codes. The UK's grid connection queue backlog — years-long waits for new projects — has made these specialists particularly valuable.
Storage dispatch / trading engineers optimise battery revenue in wholesale electricity and ancillary services markets. They build algorithms, monitor real-time market conditions, and make operational decisions about when to charge and discharge. This hybrid role sits between engineering and commercial, and people with both power systems knowledge and programming skills (Python, optimisation libraries) are in acute demand.
Pumped hydro roles
Pumped hydro careers mirror hydropower more broadly — dam and tunnel construction engineers, turbine and generator specialists, environmental impact assessors, and long-term operations teams. The key difference is that pumped hydro plants are designed to cycle daily (charging at night, discharging at peak), which creates different operational demands and wear patterns on equipment. The IHA reports that pumped storage construction workforces are typically 39% construction, 30% manufacturing, and 17% professional services.
Cross-cutting roles
Battery management systems (BMS) engineers design the electronics and software that monitor cell voltages, temperatures, and state of charge. BMS is critical for safety and performance in both EVs and stationary storage. This is a niche that bridges hardware and firmware engineering.
Battery recycling specialists are an emerging profession as the first wave of EV and grid batteries reaches end of life. The EU's new Battery Regulation mandates minimum recycled content and collection targets, creating demand for hydrometallurgists, process engineers, and lifecycle management professionals.
Business development and sales — the commercial side of energy storage is substantial. Selling BESS projects to utilities, negotiating offtake contracts, structuring financing for storage funds — these roles require technical literacy combined with commercial acumen. Senior business development managers in energy storage can earn significantly more than their engineering counterparts.

Annual gross salaries. Manufacturing technician figures exclude shift allowances (typically 12–30% on top). Business development roles typically include additional commission of 20–40%. German gigafactories under IG Metall agreements tend to pay above standard manufacturing rates. Approximate conversion: 1 GBP ≈ 1.17 EUR.
Working conditions
Energy storage work varies drastically depending on which part of the sector you're in.
Gigafactory work is factory work. Battery manufacturing runs 24/7 on rotating shifts — typically continental patterns (two days, two nights, four off) or 12-hour rotations. Clean rooms and dry rooms are climate-controlled but restrictive: no jewellery, full gowning, limited personal items. The work is repetitive but technically demanding, with strict process discipline. Dry rooms maintain humidity below 1%, which can be physically uncomfortable over long shifts.
BESS sites are construction sites, then remote facilities. During construction, BESS projects look like any electrical infrastructure buildout — outdoor work, heavy equipment, safety boots and hard hats. Once operational, most BESS assets are unmanned and monitored remotely, with maintenance teams visiting periodically. Operations and dispatch roles can often be done from an office or even remotely — one of the few genuinely hybrid opportunities in the energy storage sector.
Pumped hydro is remote infrastructure. Construction phases last years and are located in mountain valleys, underground caverns, or remote coastal sites. Operations teams are typically small (20–50 people) and based permanently near the plant. This is not city work.
Safety is a serious consideration across all segments. Lithium-ion batteries pose fire and thermal runaway risks; manufacturing environments must manage electrolyte exposure (toxic fluorine compounds) and high-voltage systems. BESS sites handle hundreds of volts DC. Pumped hydro involves the usual civil engineering hazards of heavy construction plus confined-space work in tunnels. Safety training, PPE compliance, and risk awareness are non-negotiable.
Diversity and inclusion remain a challenge, particularly in manufacturing and construction roles, which skew heavily male. Engineering and commercial roles have better gender balance, and some companies — particularly the Nordic startups and UK BESS developers — have made visible progress, but the sector overall lags behind targets.
Job security is variable. Battery manufacturing has proven volatile — Northvolt's collapse, Samsung SDI's layoffs in Hungary, FREYR's pivot away from Norway — and the pace of hiring can reverse quickly when demand forecasts shift. BESS development and operations tend to be more stable, as revenue contracts provide long-term visibility. Pumped hydro offers the most stability of all: plants operate for 50+ years and construction projects run for a decade.
Getting in: who the sector is hiring
Direct entry from adjacent industries
From automotive manufacturing: The most natural transition. Battery gigafactories use production processes — coating, drying, calendering, assembly — that overlap substantially with automotive and electronics manufacturing. Production operators, quality engineers, and process technicians can transfer with minimal retraining.
From oil and gas or chemical processing: Process engineers, HSE specialists, and project managers with experience managing hazardous materials, continuous processes, and large capital projects bring directly relevant skills to both battery manufacturing and BESS development.
From electrical engineering and power systems: Grid engineers, protection engineers, and substation specialists from utilities and network operators are in high demand for BESS grid integration and commissioning roles. The transition is nearly seamless for anyone with experience in high-voltage systems.
From IT and software engineering: Storage dispatch and optimisation roles recruit from software backgrounds — Python developers, data scientists, algorithm engineers. No energy experience required initially, though domain knowledge develops quickly on the job.
Training and qualifications
Battery technology is still poorly served by formal education. A handful of dedicated programmes exist:
- The European Battery Alliance Academy (run by EIT InnoEnergy) has trained around 50,000 workers to date, targeting 800,000 by 2025
- Several German Fraunhofer institutes offer short courses in battery cell production and testing
- Master's programmes in electrochemistry, energy storage, or battery technology are offered at TU Munich, RWTH Aachen, Imperial College London, and Uppsala University, among others
For BESS roles, relevant professional qualifications include IET/IEC standards for high-voltage systems, NEBOSH for health and safety, and grid code compliance certifications specific to each national market.
For pumped hydro, civil engineering and hydropower-specific qualifications apply — see the hydropower career guide.
The policy landscape
EU regulation is shaping energy storage employment in two distinct ways.
The EU Battery Regulation (effective 2024–2027 in phases) introduces mandatory carbon footprint declarations, minimum recycled content, and due diligence requirements for battery supply chains. This creates demand for sustainability specialists, supply chain auditors, and lifecycle management professionals — roles that barely existed five years ago.
The EU Energy Storage Action Plan and national auction programmes are driving deployment. In 2025, 80 GWh was awarded through European auctions — directly translating into construction, commissioning, and operations jobs over the following 2–3 years.
The US Inflation Reduction Act continues to pull investment westward. FREYR's pivot from Norway to the US, and Tesla's expansion of Megapack manufacturing in Texas, illustrate how subsidy regimes shape where jobs end up. European policymakers are responding — the proposed Net Zero Industry Act aims to ensure 40% of clean tech manufacturing happens in Europe — but the outcome remains uncertain.

Adjacent sectors
Energy storage sits at the intersection of several other clean energy sectors. Battery engineers frequently move between storage and EV charging infrastructure. Grid integration specialists work across storage and smart grid technologies. Hydrogen — particularly green hydrogen produced from renewable electricity — is increasingly paired with battery storage in hybrid projects, and fuel cell technology shares electrochemical fundamentals with battery R&D. Thermal energy storage is a smaller but growing niche. The boundaries between these sectors are blurring, and professionals who understand multiple storage technologies have a significant career advantage.
