H-Power plc (LSE:HPOW), the hydrogen technology company that uses ammonia to produce hydrogen and convert it into clean off-grid power, is attracting fresh attention among clean energy investors on the FTSE AIM All-Share on 4 November 2026. A new supply agreement with an existing customer and a fresh share purchase by the chief executive have revived interest in a stock that has been under pressure for much of the year.

Why H-Power Is in Focus Today

The main catalyst is the Heads of Terms agreed with Protium Green Solutions on 29 October 2026 for the supply of H-Power's HY5 decentralised ammonia cracker. Protium is already a customer, having signed an earlier agreement with H-Power in June 2026. A repeat order from an existing client is a meaningful signal for an early-stage technology business, as it suggests the customer is satisfied with the technology and sees commercial value in expanding its use.

The second Factor is insider buying. On 22 October, chief executive John Wilson purchased 236,438 ordinary shares at 8.00p each, raising his total interest to 9.4 million shares, or about 0.83% of the issued share capital. He has bought shares on several occasions over the past year, often at prices close to market lows.

What H-Power Does

H-Power plc (LSE:HPOW) develops two core product lines. Its decentralised ammonia crackers convert ammonia into hydrogen on site, with modular systems capable of producing between 0.5 and 4 tonnes of hydrogen per day. Its fuel cell generators then convert hydrogen into electricity, with power outputs ranging from 30 kilowatts to 200 kilowatts. The company aims to provide subsidy-free, commercially viable hydrogen and power solutions for industrial users, construction sites, events and other off-grid applications.

Ammonia is increasingly seen as an efficient way to transport and store hydrogen because it is easier to handle and ship. Cracking ammonia back into hydrogen near the point of use could help overcome one of the biggest barriers to hydrogen adoption: the cost and complexity of distribution.

From AFC Energy to H-Power

The company changed its name from AFC Energy to H-Power plc in May 2026, with shares trading under the new ticker HPOW from 13 May. The rebrand reflected a sharper focus on ammonia-based hydrogen production and hydrogen-to-power solutions, and a strategy centred on converting a growing pipeline into contracted orders and sustained revenue. The company also appointed a new nominated adviser in October, combining that role with joint broking duties.

Komatsu Partnership

One of H-Power's most significant relationships is its joint development agreement with Japanese heavy machinery group Komatsu. In August 2026, H-Power completed phase one of the agreement and moved into the final phase, which involves building and demonstrating its ammonia cracker integrated with a Komatsu industrial engine between September 2026 and December 2027. The total contract is worth around $2 million. A successful outcome could open doors to the construction and Mining equipment markets, where decarbonising heavy machinery is a major challenge.

Financial Position

H-Power remains an early-stage company. Revenue in its 2025 financial year was very small, while losses were substantial as it invested in product development and commercialisation. The Market Value is around £100 million at current share prices. Investors will be watching cash runway carefully, as companies at this stage often need further funding before reaching sustained profitability.

Analyst Views

Brokers covering LSE:HPOW maintain speculative buy ratings, with price targets of around 24p to 25p, implying significant upside from current levels. The speculative label reflects the high-risk, high-reward nature of hydrogen technology investing.

Risks to Consider

The main risks include slow conversion of Heads of Terms into binding contracts, delays in customer projects, competition in hydrogen technologies, policy uncertainty and the potential need for additional capital that could dilute shareholders. Hydrogen stocks have also been volatile as investors reassess the pace of the energy transition.

What Investors Are Watching Next

H-Power plc (LSE:HPOW) reaches its financial year end on 31 October, so a full-year trading update and results are expected in the coming months. Investors will look for revenue progress, order book growth, cash position and runway, and conversion of the Protium Heads of Terms into a firm contract.

Other watch points include progress on the Komatsu demonstration, new customer wins for HY5 crackers and fuel cell generators, partnerships in shipping or industrial hydrogen, and any funding announcements. Sentiment across hydrogen and clean energy stocks on the FTSE AIM All-Share will also play a role.

Bottom Line

H-Power plc (LSE:HPOW) has secured a repeat agreement with Protium and continues to advance its Komatsu partnership, while its chief executive keeps buying shares. The company is still early in commercialisation and carries significant risk, but these developments keep LSE:HPOW firmly on the radar of investors looking for exposure to ammonia-based hydrogen technology.
