Energy funding tied to Oslo shows a wide spread in disclosed round sizes, with BW Energy’s $400M round on 2025-03-28 the only disclosed amount in the hundreds of millions; the next-largest disclosed amounts are far smaller, including Ocean Oasis at $7M (2024-08-28) and several $6M rounds (ONiO at $6M on 2025-06-18; NEL Hydrogen at $6M on 2022-10-04; Hyon at $6M on 2022-01-21). Funding also concentrates into multiple time windows rather than spreading evenly: four of the 11 rows fall between 2025-04-01 and 2025-06-18 (Lithium367, BW Energy, and ONiO plus one additional 2025 entry), while the earliest disclosed rounds in this slice start on 2022-01-21 (Hyon) and extend through 2025-06-18.
Stage and disclosure patterns cluster as well. Five of 11 entries are labeled “Series Unknown” (BW Energy, Ocean Oasis, Kyoto Group, Over Easy Solar, and Aqualung Carbon Capture), and one entry is “undisclosed” (Aqualung Carbon Capture). Convertible Notes and Seed appear repeatedly (Convertible Note: Skyfri $5M on 2022-07-08 and Hyon $6M on 2022-01-21; Seed: Glint Solar $3M on 2022-06-12), while Pre-Seed and grant funding each show up once (Lithium367 $500K on 2025-04-01; NEL Hydrogen’s $6M Grant on 2022-10-04).

Frequently asked
What’s the largest disclosed energy round in this Oslo set, and how does it compare to other disclosed amounts?
BW Energy’s disclosed $400M round on 2025-03-28 is a clear outlier: it sits in the hundreds of millions while the next-largest disclosed amounts are in the single-digit millions, including Ocean Oasis at $7M (2024-08-28) and multiple $6M rounds (ONiO on 2025-06-18; NEL Hydrogen on 2022-10-04; Hyon on 2022-01-21).
Do the rounds cluster into a narrow date window, or are they spread across the full period?
They cluster at least around the latest quarter: ONiO (2025-06-18, $6M), Lithium367 (2025-04-01, $500K), and BW Energy (2025-03-28, $400M) fall in 2025, and the 11-row date range runs from 2022-01-21 (Hyon) to 2025-06-18 (ONiO).
Is Oslo consistently the geography in this listing, or are there other cities mixed in?
All 11 rows list Oslo, Norway, as the geography (e.g., ONiO on 2025-06-18 and Glint Solar on 2022-06-12 are both “Oslo, Norway”), so the dataset doesn’t show a multi-city split within the page.
How much of the list is “Series Unknown” or “undisclosed,” and does that affect size comparisons?
Five of 11 entries are labeled “Series Unknown” (including BW Energy at $400M on 2025-03-28 and Ocean Oasis at $7M on 2024-08-28), and one additional entry is explicitly “undisclosed” (Aqualung Carbon Capture on 2023-02-22). That means disclosed-size comparisons rely on fewer rows, especially around the mid-range amounts.
Which stages appear more than once, and what does that suggest about recurring funding patterns?
Convertible Note appears twice: Skyfri raised $5M on 2022-07-08 and Hyon raised $6M on 2022-01-21. Seed appears once (Glint Solar at $3M on 2022-06-12), while Pre-Seed and Grant are each singletons in this slice (Lithium367 $500K on 2025-04-01; NEL Hydrogen $6M Grant on 2022-10-04).
Are there notably small disclosed rounds that stand out against the rest of the disclosed amounts?
Lithium367’s $500K Pre-Seed on 2025-04-01 is the smallest disclosed amount in the rows shown, with the next-lowest disclosed amounts clustering around the sub-$1M to low-$millions range (e.g., Over Easy Solar at $870K on 2023-12-13) while multiple rounds land in the $6M–$7M band.
