for ****s and giggles here's what grok says that reserve size is worth today.
step 1: helium price per cubic foot (updated)
helium prices in 2025 aren’t directly quoted in the search results for march 6, but i can use the most recent data and trends:
q4 2024 data: the search results show helium prices in the us at $95,120 usd per metric ton (mt) in december 2023, and in qatar at $92,500 usd/mt fob doha by q4 2024, with a downward trend in some regions (e.g., -3% in qatar) but stability or slight increases elsewhere (e.g., 8% year-over-year in india). however, these are for bulk liquid helium in metric tons, not cubic feet of gas.
cubic feet context: industry pricing is often per thousand cubic feet (mcf). historical data (e.g., 2022) showed $375–$1,200/mcf, with $500/mcf as a mid-range estimate. web id 0 suggests $375/mcf in late 2022, with an 8% cagr over 20 years. projecting this forward:
$375 × (1.08)^2.25 (2.25 years from late 2022 to march 2025) ≈ $460/mcf, or $0.46 per cubic foot.
q4 2024 trends: web id 17 notes stable us prices in q4 2024 due to steady supply, with semiconductor and medical demand holding firm. let’s assume $500/mcf ($0.50/cu ft) as a conservative baseline, and test $750/mcf ($0.75/cu ft) for a higher-end estimate, reflecting potential supply tightness.
step 2: calculate total value in usd
for 138 billion cubic feet (138,000,000,000 cu ft):
at $0.50 per cubic foot:
138,000,000,000 × $0.50 = $69,000,000,000 usd (69 billion usd)
at $0.75 per cubic foot:
138,000,000,000 × $0.75 = $103,500,000,000 usd (103.5 billion usd)
step 3: convert usd to gbp (march 6, 2025 rate)
the exact usd/gbp rate for march 6, 2025, isn’t in the search results, but:
web id 9 (wise) shows 1 gbp = 1.287 usd as of march 6, 2025, implying 1 usd = 0.777 gbp (1 ÷ 1.287). this is the most current rate provided.
applying this:
$69,000,000,000 usd × 0.777 = £53,613,000,000 gbp (53.61 billion gbp)
$103,500,000,000 usd × 0.777 = £80,419,500,000 gbp (80.42 billion gbp)
final estimate
the value of 138 billion cubic feet of helium in gbp, as of march 6, 2025, is between £53.61 billion and £80.42 billion:
at $0.50/cu ft: £53,613,000,000
at $0.75/cu ft: £80,419,500,000
assumptions and notes
helium price: $0.50–$0.75/cu ft reflects a range from stable 2024 prices ($500/mcf) to a higher-end estimate ($750/mcf) based on historical peaks and demand from tech/medical sectors. liquid helium prices (e.g., $95,120/mt) convert differently (1 mt liquid helium ≈ 26,700 cu ft gas), but i’ve stuck with gaseous mcf pricing for consistency with your question.
