Industrial Decarbonisation Jobs in Renewable Energy

Industrial decarbonisation means taking the fossil fuel out of heat and chemistry inside factories: electrifying process heat, replacing coking coal with hydrogen-based direct reduced iron in steelmaking, and redesigning processes so that the emissions never arise in the first place. The starting point is lower than most people assume. Across every major economy, electricity supplies only around 4 to 5% of industrial heat, and the industries running on low-temperature heat and steam account for roughly 70% of global industrial energy use, emitting nearly 3 Gt of direct CO2 in 2023, half of all direct industrial emissions.

The two halves of the field

The low-temperature half is unglamorous and tractable. Food processing, paper, textiles, and chemicals need heat below 200 degrees Celsius, which industrial heat pumps, electric boilers, and mechanical vapour recompression can already deliver. The engineering question is rarely whether the technology works. It is whether a plant can be retrofitted during a two-week shutdown, and whether the electricity price against the gas price makes the sums work.

The high-temperature half is where the capital and the headlines are. Hydrogen-based direct reduced iron replaces the blast furnace, pairing an electrolyser plant with a shaft furnace and an electric arc furnace. Cement and glass face harder chemistry still, because a share of cement's emissions comes from the limestone itself rather than the fuel. These projects need chemical and process engineers, metallurgists, and people comfortable with both a steelworks and a power purchase agreement.

Why hiring is uneven

Green steel has had a difficult two years in Europe. ArcelorMittal turned down 1.3 billion euros of German subsidy in June 2025 and cancelled the conversion of its Bremen and Eisenhüttenstadt plants, citing German energy costs, tight funding deadlines, and a European steel market under pressure from weak demand and imports. Several other integrated projects have slipped. The economics turn on the spread between electricity and gas prices and on whether buyers pay a premium for low-carbon metal, and neither has moved the way developers modelled in 2022.

That is visible in what is advertised. The roles listed under this tag on Rejobs skew towards policy, research, and early project work rather than construction: a Senior Policy Advisor on EU industry transition, a Senior Research Associate on an industry programme, a PhD position on tramp elements in green steel production, and a Project Manager for electrification of the process industry. When capital projects are deferred, the analytical and advocacy roles are what remain funded.

Who hires

Four employer types. Equipment and engineering groups building the plant, where Siemens Energy has recruited in Vienna. Policy institutes and think tanks shaping the rules, including E3G in Brussels and the American Council for an Energy-Efficient Economy in Washington. Universities such as TU Delft, which carries much of the metallurgical research. And the industrial companies themselves, which tend to recruit through their own channels rather than through job boards.

The skill combination that pays is narrow and specific: someone who understands a production process from the inside, and also understands electricity procurement, carbon accounting, and the permitting that a retrofit triggers. Energy efficiency work is the usual route in, since the cheapest decarbonisation step is still the heat a plant stops wasting, and energy policy is the other, given how much of this sector's economics is written into regulation rather than set by the market.
