Zero Petroleum Secures £2.2m in Latest Funding Round, Valued at Over £100m

Zero Petroleum Limited, a London-based innovator in synthetic fuel manufacturing, has successfully secured £2.2m in its latest funding round. The investment, finalised with an allotment date of April 23, 2026, and filed on April 24, 2026, values the company at an estimated post-money valuation of £100.2m. This capital injection underscores continued investor confidence in the company's mission to provide fossil-free alternatives for hard-to-decarbonise industries.

Founded on March 28, 2019, Zero Petroleum is at the forefront of developing synthetic petrol, diesel, and jet fuel. The company's proprietary technology utilises air and water to create fuels that are chemically identical to their fossil counterparts, allowing them to be used in existing vehicles and infrastructure without modification. This approach directly addresses the critical challenge of decarbonising sectors such as aviation, heavy plant machinery, and agriculture, which currently lack viable electrification pathways.

According to its latest available accounts, Zero Petroleum reported a profit/loss of £-5,180,250, reflecting the significant investment typically required for deep tech research, development, and scaling. The company currently employs 53 individuals, a team dedicated to advancing its innovative fuel production processes and bringing its sustainable solutions to market.

The recent £2.2m funding round, at a £100.2m post-money valuation, follows a dynamic period of fundraising for Zero Petroleum. The company has demonstrated a consistent ability to attract capital, with several notable rounds preceding this latest investment. In September 2025, Zero Petroleum completed a Series B round, raising £5.9m at a valuation of £102.2m. This was closely preceded by a £255k raise on September 18, 2025, at a valuation of £18.8m, and a substantial £6.1m round on June 6, 2025, which valued the company at £28.4m. Earlier in 2025, on April 30, the company secured £1m at a valuation of £101m.

Looking further back, Zero Petroleum's funding journey includes a £2.4m investment on July 13, 2022, at a £23.3m valuation, and a £102.2k round on April 6, 2022, valuing the company at £2.6m. Its initial recorded funding round was on September 20, 2021, where it raised £200k at a £2.5m valuation. The valuation trajectory, particularly the fluctuations observed in 2025, highlights the complex and often non-linear nature of growth funding in the deep tech sector, with the company consistently demonstrating its ability to rebound to high valuations. The current round's valuation of £100.2m positions it slightly below the Series B valuation from September 2025, indicating a strategic raise to support ongoing operations and development.

Zero Petroleum's continued success in securing investment aligns with broader trends in the UK's cleantech and deep tech funding landscape. While overall UK climate tech funding saw a decline in 2025 from its 2023 peak, this largely reflected the absence of mega-deals rather than a collapse in underlying activity. Excluding these large deals, base funding has remained steady at approximately £1bn annually since 2021, with the median deal size growing from £968k in 2020 to £3m in 2024, signalling a maturing early-stage ecosystem. Deep tech, the category Zero Petroleum falls into, now accounts for 31% of all UK VC funding, a threefold increase over the last decade, and the UK ranks third globally for deep tech venture capital since 2019.

The synthetic fuels sector, particularly sustainable aviation fuel (SAF), is a key area of focus for decarbonisation efforts. The UK government has demonstrated strong support for this nascent industry through various initiatives. In February 2026, Zero Petroleum Limited itself was awarded £181,000 in funding through the UK Sustainable Aviation Fuels (SAF) Clearing House. This grant is specifically aimed at accelerating the testing, certification, and commercialisation of next-generation sustainable aviation fuels, a cornerstone of the UK's strategy to decarbonise its aviation sector. The UK has set an ambitious target for SAF to constitute at least 10% of all jet fuel used in flights originating in the UK by 2030.

Recent activity in the sector further illustrates this momentum. Another UK-based synthetic fuel startup, Rivan, recently raised £25m in April 2026 to scale its production capacity for synthetic natural gas, targeting heavy industries. This parallel investment highlights the growing recognition of synthetic fuels as a crucial component in achieving energy security and decarbonisation goals, especially for hard-to-electrify sectors like aviation and heavy industry. The broader clean energy sector in the UK is also set for significant growth, with government plans to double investment to £30bn annually by 2035. However, it is worth noting that some analyses suggest an imbalance in UK green spending, with a greater allocation towards carbon capture, utilisation, and storage (CCUS) and hydrogen compared to other cleantech startups.

Zero Petroleum's latest funding round positions the company to continue its vital work in developing and scaling fossil-free fuel alternatives. As the UK and global economies push towards net-zero emissions, companies like Zero Petroleum, with their innovative deep tech solutions, are poised to play a crucial role in transforming challenging sectors and contributing to a more sustainable future.
