German electrolyser maker Sunfire raises 315 million euros for green hydrogen

German electrolyser producer Sunfire raised 315 million euros, including a 215 million euro Series E round and a 100 million euro EIB loan, to scale green hydrogen technology. For Indian green hydrogen developers, the funding underscores rising investor and development-bank backing for electrolyser manufacturing capacity.

Dresden-based electrolyser producer Sunfire raised 315 million euros (USD 342 million), comprising a 215 million euro Series E equity round and a term loan of up to 100 million euros from the European Investment Bank, to accelerate development and industrialisation of its green hydrogen technologies. Founded in 2010, Sunfire produces pressurised alkaline and high-temperature solid oxide electrolysers that generate green hydrogen and syngas from water steam, renewable electricity, and captured CO2. The company plans to install several gigawatts of electrolysis capacity by 2030 and has access to around 200 million euros in undrawn approved grant capital.

Sunfire is the primary beneficiary, strengthening its position in scaling industrial electrolysers for the hydrogen economy. New investors LGT Private Banking, Ahren Innovation Capital, GIC, and Carbon Equity joined the round, while existing shareholders including Lightrock, Carbon Direct Capital, the Amazon Climate Pledge Fund, Planet First Partners, and Blue Earth Capital increased their investment. Energy-intensive industries seeking climate-neutral alternatives to fossil energy are affected, as scalable electrolysers are foundational to a green hydrogen business environment, according to EIB Vice President Nicola Beer. The European clean-tech sector benefits from reinforced hydrogen production capability.

Industry players should monitor Sunfire's plans to install several gigawatts of electrolysis capacity by 2030 in large-scale green hydrogen projects, which signals scaling capacity for the sector. Companies in energy-intensive industries seeking renewable hydrogen and syngas should track the industrialisation of pressurised alkaline and solid oxide electrolysis technologies. Investors and project developers should note the involvement of the EIB and climate-focused funds as indicators of available financing. Sunfire also has access to around 200 million euros in undrawn grant capital, supporting continued growth.
