Dresden/ Solingen/ Zug (CH)/ The elec­tro­ly­sis company Sunfire has recei­ved EUR 86 million from inves­tors. Parti­ci­pants in the expan­ded Series D finan­cing round include Copen­ha­gen Infra­struc­ture Part­ners (CIP), through its Copen­ha­gen Infra­struc­ture Energy Tran­si­tion I fund, and Blue Earth Capi­tal. Sunfire thus increa­ses its Series D capi­tal raising to a total of €195 million ($215 million). In addi­tion, CIP is ente­ring into an agree­ment with Sunfire to purchase pres­su­ri­zed alka­line elec­tro­ly­sers with a total capa­city of up to 640 MW for use in its multi-GW power-to‑X projects across Europe.

Up to 640 MW elec­tro­ly­sis for CIP

Through its Copen­ha­gen Infra­struc­ture Energy Tran­si­tion Fund I, CIP is support­ing Sunfire in the indus­tria­liza­tion of its hydro­gen tech­no­lo­gies. The fund company is one of the world’s largest project deve­lo­pers for rene­wa­ble ener­gies and is active in the areas of offshore wind power, energy storage and power-to‑X, among others.

To imple­ment its plan­ned power-to‑X projects, CIP needs relia­ble, indus­trial elec­tro­ly­sis plants. The avai­la­bi­lity of these is still very limi­ted world­wide. In a frame­work agree­ment, the project deve­lo­per ther­e­fore also secu­res access to elec­tro­ly­sis capa­ci­ties from Sunfire. In the coming years, CIP plans to purchase pres­su­ri­zed alka­line elec­tro­ly­sers with a total capa­city of up to 640 MW and use them in its multi-GW projects throug­hout Europe.

“This agree­ment adds huge value for all parties invol­ved,” says Sunfire CEO Nils Aldag. “CIP can rely on our advan­ced alkali elec­tro­ly­sers and on our dedi­ca­ted team of experts — at the same time demons­t­ra­ting that we are a relia­ble part­ner for giga­­watt-scale projects.”

Invest­ment company BlueE­arth contri­bu­tes capi­tal and expertise

As part of its climate stra­tegy, BlueE­arth is also part­ne­ring with Sunfire. The globally active invest­ment company was foun­ded by the Swiss Part­ners Group and built up with its support.

BlueE­arth places a high value on being invol­ved beyond its invest­ment. To support Sunfire in its growth, the new part­ners are ther­e­fore contri­bu­ting their entre­pre­neu­rial expe­ri­ence and expert know­ledge around the topic of growth and climate protection.

With its elec­tro­ly­sis solu­ti­ons, Sunfire is addres­sing the key chall­enge of today’s energy system: the provi­sion of green hydro­gen and synthe­sis gas as a climate-neutral substi­tute for fossil energy. Sunfire’s inno­va­tive and proven elec­tro­ly­sis tech­no­lo­gies enable the decar­bo­niza­tion of indus­trial sectors that today are still depen­dent on oil, gas or coal.
