·    Continued to operate its demonstration and test unit in Lincolnshire, UK, which has been run on methane, natural gas, biomethane and flare gas compositions. 

Strohm Holding B.V., a Netherlands-based hydrogen pipeline company: (10% of NAV)

·    Successfully completed new €30 million capital raise. The round was led by a €20 million investment by new investors, as well as existing shareholders, including €1.2 million from HydrogenOne through convertibles.

·    Won third and largest ever thermoplastic composite pipe ("TCP") contract from ExxonMobil Guyana. The use of TCP manufactured by Strohm allows clients the ability to significantly reduce the CO2 footprint of their pipeline infrastructure.

·    Added new TCP product based on carbon fibre and polyvinylidene fluoride, to be used for carbon capture and storage applications to its portfolio. As a totally corrosion-free solution, with a 30-year design life and a proven smaller carbon footprint compared to steel, the product is suitable for injecting CO2 offshore, both in depleted gas fields and aquifers.

·    In July 2024, announced the award of a new TCP contract by TotalEnergies, for the deployment of CO2 specification flowlines in over 2,000 meters of water in Brazil, the first time TCP has been deployed in ultra-deep water.

Bramble Energy, a UK-based fuel cell and portable power solutions company: (9% of NAV)

·    Successfully completed Scale-up Readiness Validation (SuRV) programme, funded by the Advanced Propulsion Centre UK. As part of SuRV, Bramble Energy was awarded £1.8 million to develop an optimised fuel cell stack assembly with the capacity to produce up to 2,000 50 kW stacks/year. The completion of SuRV has seen Bramble Energy simplify its fuel cell stack assembly process through the design of its already trademarked Printed Circuit Board Fuel Cell (PCBFC™), which includes integrated membrane electrode assembly into unitised PCB modules (cells).

·    Bramble Energy's 'Hydrogen Bus' reached a crucial milestone, taking a significant innovative step toward transforming the transport sector. One year after the £12.7 million landmark project commenced, the concept designs for the hydrogen system and double-decker bus have been completed and are now moving into the manufacturing phase. The project, which was funded by the Advanced Propulsion Centre UK, is expected to save nearly six million tonnes of CO2 from being emitted.

HH2E AG, a green hydrogen project developer with a focus on industrial customers in Germany: (9% of NAV)

·    Completed its corporate consolidation by the exchange of interests in five SPVs including Thierbach, and interests in a new SPV, Lubmin, for equity in HH2E.

·    Entered into an agreement with Suldal municipality for the sale of Gen2's property at Jelsa in Suldal, covering a total of 16,800 sqm, with a combined building mass of 8,100 sqm.

·    Appointed Mr Kjetil Bøhn as new CEO to support the company's next phase, when entering FID and large-scale hydrogen project.

Investment Adviser's commentary

The key contributors to the quarterly NAV were valuation uplifts in multiple private holdings including HiiROC, HH2E and Bramble, partly offset by decreases in the valuation of Cranfield Aerospace, Gen2 Energy and Strohm adding 1.17 pence (1.1%) per share to the NAV.

The portfolio weighted average discount rate at 30 June 2024 was 13.3%, lower than 31 March 2024 (14.3%), as a result of a decrease in the small company premiums, increasing NAV by 2.86 pence per share. The portfolio weighted average discount rate at 30 June 2023 was 13.7%, higher than 31 March 2024, increasing 30 June 2024 NAV by 2.05 pence per share.

During the 12 months to 30 June 2024, private portfolio companies delivered an aggregate unaudited £76 million in revenue, an increase of 44% compared to the 12 months to 30 June 2023, and a slight reduction compared to the prior quarter. Revenue growth reflects the build out of capacity to meet strong order books for hydrogen supply chain equipment.

Meanwhile, portfolio companies continue to attract substantial fresh capital from strategic investors, with over £140 million investment completed in the quarter. This underscores the Company's growth strategy of investing in distinctive clean hydrogen growth technologies alongside industrial companies and specialist investors.

Investments in the quarter totalled £1.2 million in follow-ons in portfolio companies, including Strohm and Cranfield Aerospace. Cash and cash equivalents were £1.7 million, with an additional £0.3 million of listed hydrogen companies at the end of the quarter.

A new strategic investor invested in HiiROC, and combined with further investment from Cemex in 2023, and orders for equipment, has resulted in an increase of 13% in the Company's carrying value (£23.0 million) at 30 June 2024, compared to 31 March 2024, and an 68% increase compared to 31 December 2023.

A corporate consolidation of HH2E was completed in Q2 2024. The Company has exchanged its development rights for five project SPVs, including the Thierbach SPV, for equity in HH2E. In parallel, the Lubmin SPV, which was previously carved out of the Company's direct holdings, has also been combined with HH2E in a non-cash transaction for the Company. The 30 June 2024 NAV for HH2E reflects this transaction, by combining previous holdings in Thierbach with HH2E, with a 38% accretion (£3.4 million) in value of the combined position compared to 31 December 2023.

Baker Hughes made a strategic investment in Elcogen, following investment from HD Hyundai in 2023, part of a €140 million total fundraise. This supports the go-ahead of the Elco-1 plant project in Estonia and has resulted in a 22% increase in carrying value (£26.2 million) since 30 June 2023.

Strohm closed a €30 million funding round, led by new and existing investors, including €1.2 million from HydrogenOne through convertibles. The new investment provides funding for further capacity expansion at Strohm's Netherlands plant, which underpins the Company's confidence in the medium-term growth outlook, despite near-term delays in revenue delivery.

At 30 June 2024, the Company has invested in a portfolio of private investments, in the UK and Europe, representing 99.8% of its invested portfolio by value. Additional investment in strategic, global hydrogen equities represented 0.2% of the invested portfolio. The Company continues to exit from its listed holdings, and to focus on private investments.

The portfolio continues to perform in line with the expectations of the Investment Adviser, HydrogenOne Capital LLP.
