I’ve been tracking penny stocks closely lately, and one name keeps catching my eye: Clean Power Hydrogen (LSE: CPH2).
This tiny company’s market cap has more than doubled this year, surging from around £30m to £66m today. It’s up a staggering 169% since May last year (2025).
So I had to take a closer look: is this runaway success a genuine opportunity, or your classic penny share trap?
What does it do?
Clean Power Hydrogen was founded in 2012 and is headquartered in Doncaster. This green hydrogen technology and manufacturing company develops something truly innovative: the IP-protected Membrane-Free Electrolyser (MFE).
In simple terms, it makes two very pure gases at the same time: hydrogen and oxygen that’s even cleaner than what’s used in hospitals.
Most hydrogen makers need special expensive membranes or barriers to work, but these break down, get clogged up, and cost a lot to fix. Clean Power Hydrogen’s system skips those parts entirely, so it doesn’t clog as easily, breaks down less often, and costs much less to keep running.
So the hydrogen production units it manufactures could revolutionise how we think about clean energy.
Where Clean Power Hydrogen excels
The company’s target markets are life sciences, healthcare, mobility, and data centres, including long-duration backup storage and dispatch applications.
That’s where it gets interesting for investors: there’s potentially huge demand from industries where hydrogen and oxygen could improve process efficiency, such as wastewater treatment and semiconductor fabrication.
As Murray Douglas, Wood Mackenzie’s Vice President for Hydrogen and Derivatives Research, recently said:
Projects advance where policy and offtake align, and stall where either remain uncertain. 2026 will separate viable hydrogen markets from those built on policy ambition alone.
But before you get too excited, consider this: shares are down 77.2% in five years. So is the recent jump just a small blip in an otherwise downward trajectory?
The reason for the rally
Clean Power Hydrogen recently inked a non-binding partnership with BKW subsidiary Abe to cover the supply, installation, commissioning, and maintenance of electrolysers across Abe and BKW’s markets. BKW is one of Switzerland’s largest energy supply companies, which adds serious credibility to this deal.
The company is seeking to monetise curtailed wind or solar capacity, something recently highlighted by National Grid‘s cost-saving efforts. This approach could unlock significant value from wasted renewable energy.
But like most penny stocks, it’s not yet profitable. So does it have the financial strength to keep delivering?
Let’s look at the hard numbers, because that’s what really matters:
- Revenue (HY25): £4,000
- Cash (financing): £5.59m
- Total debt: £708,000
- Total assets: £11.85m
These figures show a company with more cash than debt and solid long-term assets. But the question is: can it keep securing financing until it becomes profitable?
The bottom line
Clean Power Hydrogen offers a compelling narrative: renewable energy linked to data centre and semiconductor opportunities.
But it’s very risky as a small cap with limited liquidity and heavy reliance on one big partnership. The non-binding nature of that BKW deal means nothing’s guaranteed yet.
Still, for investors keen on getting in early on the renewable energy transition, I think it’s worth considering. Albeit, only as a small allocation of around 1%-2% in a larger, diverse portfolio.
Renewable energy continues to drive some of the most innovative market moves today, and it’s a sector I plan to cover more deeply in 2026.
