10 Things to Know About Hydrogen in the UK

Hydrogen gets mentioned constantly in energy conversations. It shows up in government strategies, investor pitches, and net zero roadmaps without much explanation of what is actually happening on the ground. Most coverage stays at the surface big numbers, ambitious targets, not much detail underneath.

So here is a more grounded version. Ten things worth actually knowing about hydrogen in the UK right now.

1. The UK Already Uses Hydrogen Just Not the Clean Kind

This surprises people. Britain has been producing and consuming hydrogen for decades in oil refineries, fertiliser manufacturing, and chemical processing. The problem is that almost all of it comes from natural gas, releasing CO₂ in the process.

The transition is not about creating demand from scratch. The demand already exists. What needs to change is how hydrogen gets made.

2. Not All Hydrogen Is Green

Green, blue, grey, pink hydrogen gets colour-coded depending on how it is produced. Grey comes from natural gas with no carbon capture. Blue adds carbon capture to that process. Green uses renewable electricity to split water through electrolysis.

Then there are thermochemical routes like the process Hydrogen Transition Energy (HTE) uses  which convert non-recyclable waste into clean hydrogen without drawing on the electricity grid at all. The colour coding does not always capture that, which is part of why the conversation gets confusing.

3. The UK Government Has Put Real Money Behind It

The Hydrogen Production Business Model gives producers a guaranteed revenue mechanism to bridge the gap between production costs and what the market will currently pay. The Net Zero Hydrogen Fund provides capital grants. HAR1 Hydrogen Allocation Round 1 selected eleven projects for early commercial support.

These are not vague promises. They are specific funding mechanisms with named projects attached. The policy framework is more developed than most people realise.

4. Heavy Industry Is the Biggest Opportunity

Hydrogen heating for homes gets a lot of column inches. But the stronger near-term case for hydrogen is in industry steel, cement, chemicals, glass manufacturing. These sectors run at temperatures and energy densities that electricity cannot practically deliver.

Decarbonising UK heavy industry without hydrogen is not impossible. It is just considerably harder and more expensive. Hydrogen is the practical route for sectors that cannot simply plug into a renewable electricity supply.

5. Hydrogen Can Be Stored for Months

This does not get talked about enough. Batteries store electricity for hours, maybe days. Hydrogen stored in tanks, salt caverns, or repurposed gas infrastructure holds energy for weeks and months without significant loss.

For a grid increasingly dependent on intermittent wind and solar, seasonal storage matters enormously. Surplus summer renewable generation stored as hydrogen and drawn on during winter demand peaks that is a problem hydrogen solves that batteries currently cannot.

6. The UK's Geography Is a Real Advantage

Offshore wind, tidal resources, the North Sea, deep engineering expertise from decades of oil and gas the UK has a combination of assets that few countries can match for hydrogen production. The infrastructure, the skills, and the wind resource are already here. The transition is about redirecting them rather than building from zero.

7. Waste Is Becoming a Hydrogen Feedstock

Most people associate hydrogen production with electrolysis splitting water with electricity. But non-recyclable waste is emerging as a serious feedstock for hydrogen through thermochemical processes.

Hydrogen Transition Energy (HTE) is the clearest example in the UK. Based in Broadstairs, Kent, HTE uses plasma-assisted gasification at temperatures above 3,000 degrees to convert plastics, tyres, automotive shredder residue, and municipal solid waste into fuel cell grade hydrogen. The waste that currently costs money to dispose of becomes the raw material for clean fuel.

BBC News covered HTE's planning submission for the UK's first industrial-scale waste-to-hydrogen plant in April 2026. That is not a concept study. It is a planning application for a real facility.

8. Hydrogen Vehicles Are Already on UK Roads

Hydrogen fuel cell cars, buses, and trucks are not a future technology in the UK. They are operating now in London's bus fleet, in logistics trials, and in passenger vehicles from manufacturers including Toyota and Hyundai.

The limiting factor is refuelling infrastructure, which remains sparse outside major cities. But the vehicles exist, they work, and the refuelling network is slowly growing.

9. Carbon Capture Changes the Equation for Some Projects

Blue hydrogen made from natural gas with carbon capture sits in contested territory environmentally. The argument against it is that methane leakage during gas extraction can undermine the carbon savings. The argument for it is that existing gas infrastructure can be repurposed quickly and at scale.

The honest position is that blue hydrogen is better than grey and worse than green. Whether it has a long-term role or functions as a bridge technology depends on how quickly green and waste-based routes scale up.

10. The First Industrial Waste-to-Hydrogen Plant in the UK Is in Planning Right Now

This is the most underreported development in UK hydrogen and it deserves more attention than it gets.

Hydrogen Transition Energy (HTE) has submitted planning permission for a facility in Kent that would be the first of its kind at industrial scale in the country. Plasma-assisted gasification. Temperatures above 3,000 degrees. Non-recyclable waste in, fuel cell grade hydrogen out. Captured CO₂ and inert construction aggregate as by-products.

Nothing to landfill. Nothing incinerated in the conventional sense. A waste problem and a clean energy problem addressed by the same process.

If planning is approved, HTE's Kent facility will not just be a milestone for the company. It will be a milestone for the UK hydrogen sector proof that waste-to-hydrogen has moved from idea to industrial reality.

Conclusion

Hydrogen in the UK is not one story. It is a dozen overlapping stories happening simultaneously policy mechanisms, industrial projects, vehicle trials, offshore ambitions, and waste-to-hydrogen facilities in planning in Kent.

The ten points above do not cover everything. But they cover the things that tend to get missed when the conversation stays at the level of targets and announcements.

The gap between what is being promised and what is being built is closing faster than most coverage suggests. HTE is one of the clearest examples of that.

Frequently Asked Questions

Is hydrogen energy actually available in the UK right now?

Yes, in limited but growing applications. Hydrogen buses are operating in London. Fuel cell vehicles are on UK roads. Industrial hydrogen is produced and used daily, though mostly from natural gas currently. Green and low-carbon hydrogen production is scaling up through projects like HTE's Kent facility, with broader commercial availability expected to grow significantly through the late 2020s.

What is the difference between green and blue hydrogen?

Green hydrogen is produced by splitting water using renewable electricity through electrolysis no carbon emissions in the process. Blue hydrogen comes from natural gas with carbon capture added to reduce emissions. Grey hydrogen is natural gas without any capture. Waste-to-hydrogen, the route HTE uses, sits outside these categories it uses non-recyclable waste as feedstock and captures CO₂ during the process.

What is Hydrogen Transition Energy (HTE)?

HTE is a UK hydrogen company based at the Kent Innovation Centre in Broadstairs. They are developing the country's first industrial-scale waste-to-hydrogen plant using plasma-assisted gasification technology. Their process converts non-recyclable waste plastics, tyres, automotive shredder residue, municipal solid waste into fuel cell grade hydrogen meeting ISO 14687 standards. Planning permission was submitted in April 2026 and the project received BBC News coverage.

Why does the UK need hydrogen if it has wind and solar?

Renewable electricity cannot decarbonise everything. Heavy industry, long-haul transport, shipping, and aviation need energy at densities and in forms that electricity cannot currently deliver at scale. Hydrogen fills those gaps. It also provides long-duration seasonal storage holding surplus renewable energy for months which battery technology cannot yet match at any meaningful scale.

How does waste-to-hydrogen help with the UK's waste problem?

Non-recyclable waste the material left after sorting and recycling currently goes to landfill or incineration. Both are expensive and environmentally problematic. Waste-to-hydrogen converts that same material into clean hydrogen fuel through thermochemical processes, with captured CO₂ and inert slag as by-products. It closes the loop on difficult waste while adding to the UK's clean hydrogen supply solving two problems with one process.
