Across the 19 most recent funded energy entries in Stockholm, the largest disclosed round is Stockholm Exergi’s $199M (2022-04-01). That figure sits far above the next set of large disclosed rounds, including Cloover at $114M (2024-05-28) and OX2 at $77M (2024-12-11), while several other disclosed amounts cluster below $50M (e.g., Tether $2M on 2025-06-19; Exeger $38M on 2023-12-19). Timing is similarly concentrated: nine rounds were dated from 2024-05-28 through 2025-07-07, with multiple $3M rounds in spring 2025 (Climeon $3M on 2025-05-15; Midsummer $3M on 2025-04-09). Stage labeling is also uneven: 6 of 19 rows are “Series Unknown,” and 2 of 19 disclosed amounts are “undisclosed” (CorPower Ocean on 2025-07-07; Scandinavian Biogas Fuels International on 2022-12-09). The window spans from 2020-08-05 (Krafthem) to 2025-07-07 (CorPower Ocean).

Frequently asked
What stands out as the largest disclosed round, and how does it compare to the rest of the disclosed amounts?
Stockholm Exergi’s $199M round on 2022-04-01 is the clear disclosed outlier in this list, well above the next-largest disclosed amounts such as Cloover’s $114M (2024-05-28) and OX2’s $77M (2024-12-11). Many other disclosed rounds are notably lower, including Tether’s $2M (2025-06-19) and Fever’s $11M (2024-02-15).
Are there timing clusters within the 19 most recent entries, or are dates spread evenly?
Dates are more clustered near the top of the list: nine rounds fall between 2024-05-28 (Cloover) and 2025-07-07 (CorPower Ocean). There is also a small spring-2025 cluster at the low end of disclosed amounts, with two $3M rounds in close succession: Midsummer on 2025-04-09 and Climeon on 2025-05-15.
How often do stage labels come through as “Series Unknown” or “undisclosed,” and does that affect comparisons?
Stage ambiguity is frequent: 6 of 19 rows are labeled “Series Unknown” (e.g., OX2 on 2024-12-11; Alight on 2025-03-04), and 2 of 19 amounts are “undisclosed” (CorPower Ocean on 2025-07-07; Scandinavian Biogas Fuels International on 2022-12-09). That combination limits how confidently amounts can be compared across clearly labeled stages.
Which stage buckets appear most repeatedly among labeled rounds?
Among explicitly labeled stages (excluding blank and “Series Unknown”), Seed and Series A recur multiple times: Seed appears for Krafthem’s 2020-08-05 is blank, but the labeled Seed entries here are Cloover (2024-05-28, $114M) and Fever (2024-02-15, $11M); Series A appears for Novatron (2025-03-19, $11M) and Greenely (2024-07-26, $8M). Series B also shows up more than once, including Aira (2024-10-16, $69M) and CorPower Ocean (2025-07-07, undisclosed).
Which entries are worth calling out as amount outliers on the low end?
At the low end of disclosed amounts, Tether’s $2M on 2025-06-19 is the smallest disclosed figure in this set, followed by Krafthem’s $500K on 2020-08-05. These sit well below mid-to-upper disclosed rounds such as Exeger’s $38M (2023-12-19) and Tethys Oil’s $60M (2024-08-02).
