Hydrogen Electrolyser Finance

Spread the cost of a hydrogen electrolyser from £300,000 to £5,000,000+ with flexible finance options. HP, lease, or refinance, compare rates from a specialist lender panel.

Can you finance a hydrogen electrolyser?

Yes, hydrogen electrolysers are financed as a standard asset purchase, usually on hire purchase or a lease, with the machine itself acting as the security. UK prices typically run £300,000 to £5,000,000, and most deals are written over 60–120 months with a deposit of around 20–30%. Decisions typically take weeks to months. Used machines are financeable too, usually with a shorter term.

Representative example

On a purchase price of £1,200,000: a 10% deposit of £120,000, then 48 monthly payments of £25,314 at 5.9% APR representative (fixed). Total amount payable £1,335,072, including the deposit. The rate you are offered depends on your business and the asset.

What buyers actually specify

Guide prices for sizing a finance agreement, not quotes. Manufacturers in this market mostly price on application, so where a current UK list price could not be confirmed the row describes a specification class rather than naming a model. Your supplier quote is what the agreement is written against.

Machine or specification	Guide price	Type
ITM Power containerised PEM electrolyser, sub-MW to several MW scale	Roughly £700,000 – £900,000 per MW of capacity, based on ITM Power's published pricing for larger systems; smaller containerised units cost more per MW	PEM Electrolyser
Small containerised electrolyser for on-site industrial gas or forklift refuelling (specification class)	£300,000 – £800,000	Small Containerised Electrolyser
Mid-scale electrolyser for a hydrogen refuelling station (specification class)	£1,000,000 – £2,500,000	Refuelling Station Scale Electrolyser
Multi-MW electrolyser plant (specification class, scales with ITM Power's published per-MW pricing above)	£3,000,000 – £5,000,000+	Multi-MW Electrolyser Plant

Tax benefits

A hydrogen electrolyser is a major piece of fixed industrial plant, and a containerised or skid-mounted unit generally qualifies for the Annual Investment Allowance, letting you set the cost against taxable profits up to the prevailing AIA limit, though at this scale many projects exceed that limit and rely on writing down allowances for the remainder. Where an electrolyser is integrated into permanent site infrastructure, pipework, compression and storage, that surrounding installation can be treated differently from the electrolyser unit itself for capital allowances, so this is a project where getting specialist tax advice alongside the finance is essential rather than optional.

Market context

Hydrogen electrolysers at commercial scale are bought by industrial gas users wanting on-site low-carbon hydrogen production, transport operators building hydrogen refuelling infrastructure for buses or heavy goods vehicles, and energy companies developing larger green hydrogen production projects, generally substantial businesses or well-funded projects rather than small or medium enterprises, given the scale of investment involved. Because the technology is still relatively new and installations are large, fixed and highly specialised, there is effectively no established used market for electrolysers, so lenders assess these deals overwhelmingly on the strength of the sponsoring business, any offtake or supply agreements underpinning the project, and available grant funding, rather than on the resale value of the equipment itself. Replacement or expansion is generally driven by production demand growing or electrolyser efficiency improving with newer stack technology, rather than existing units failing.

Bad credit?

Several of our 200+ lenders specialise in businesses with imperfect credit histories. You may need a larger deposit or personal guarantee, but options exist. Checking your options here does not affect your credit score, because we do not run a credit search to match you. A lender will run their own checks only if you decide to apply.

Frequently asked questions

Is hydrogen electrolyser finance the same as for other equipment?

Not really. At this scale and given how new and specialised the equipment is, with no meaningful used market to fall back on, lenders assess these deals much more like project finance than a standard equipment purchase, weighing the sponsoring business's balance sheet, any long-term offtake or supply agreements, and available grant funding alongside the electrolyser itself. A specialist project finance lender or broker experienced in hydrogen infrastructure is usually a better route than a general asset finance provider.

Can grant funding be combined with asset finance for an electrolyser?

Often, yes. UK and devolved government hydrogen funding schemes have supported a number of electrolyser projects, and grant funding is commonly layered alongside debt or lease finance to reduce the amount that needs to be borrowed. The exact structure depends on the scheme and timing, so it's worth involving your finance provider early if you're applying for grant support in parallel.

What deposit or equity contribution is typical?

Deposits or equity contributions of 20% to 30% are common at this scale, reflecting the size, novelty and lack of a resale market for the equipment. Projects with a strong offtake agreement, an established industrial sponsor, or confirmed grant funding can sometimes negotiate more favourable terms, since these reduce the lender's perceived risk.

How long does it take to arrange finance for an electrolyser project?

Given the scale and complexity, expect a process measured in months rather than days, involving technical due diligence, review of any offtake agreements, and coordination with any grant funding. This is very different from the 24 to 48 hour turnaround typical of smaller equipment finance, so it's worth building the finance timeline into your overall project plan from an early stage.
