HydrogenOne Capital Growth plc 

('HydrogenOne' or the 'Company')

Publication of 2024 Sustainability Report

HydrogenOne Capital Growth plc, the first London-listed fund investing in clean hydrogen for a positive environmental impact, is pleased to note the publication of its 2024 Sustainability Report.

In 2024, the Company continued to focus its commitment to ethical investment practices and enhanced climate stewardship.

At its heart, the clean hydrogen industry is an opportunity to remove 830 mtpa of GHGs from the polluting and growing grey hydrogen sector, and to address many multiples of that figure over time in the transport, heat and power sectors. This is why 'avoided GHG emissions' remains a key metric for the Company.

Highlights:

·    £116.3 million deployed in low-carbon growth investments (FY2023: £113.7 million);

·    Total GHG emissions in 2024 were 230t CO2e, 18% lower than 2023 (279 tCO2e);

·    As an Article 9 fund, the highest sustainability classification under EU SFDR;

·    Over 132,800 tonnes of Greenhouse Gas (tCO2e) emissions avoided in FY2024 (FY2023: 91,116 tCO2e) (over 576 times the combined scope 1, 2 and 3 emissions of the Company in the same period) and 274,534 tCO2e (FY2023: 141,695) since IPO;

·    Potential 537,193 megawatt-hour (MWh) lifetime clean energy capacity in FY2024 (FY2023: 571,294 MWh) and 1,334,487MWh (FY2023: 797,294) since IPO; and

·    The Company's investments either directly or indirectly displace fossil fuels, making a clear contribution to achieving the Paris Accords target of limiting global temperature rises to below 2 degrees and ideally limiting them to 1.5 degrees.
