Weekly Synthesis
This week’s energy indicators reveal a market undergoing structural transformation. Brent oil prices oscillate around $68-69/barrel, reflecting the precarious balance between geopolitical tensions and supply-demand fundamentals. European natural gas remains under pressure at €31.79/MWh, benefiting from robust LNG imports but facing uncertainties about Russian supply. This pivotal period illustrates the transition from a fossil fuel energy system to a diversified mix where renewables gain influence on price formation and investment strategies.
- Oil Prices (Brent, WTI)¹
-
Strategic Importance: Global benchmarks for crude oil pricing, influence global inflation, industrial margins, and energy geopolitical balances.
Weekly Data: Brent closed at $68.99/barrel on September 3 (-5.10% year-on-year), WTI at $65.59/barrel (+2.47% on September 2 session).
Analysis: The divergence between geopolitical tensions (Iran sanctions, Ukraine attacks) and OPEC+ increases (547,000 bpd) maintains volatility. Anticipation of Q4 2025 surplus weighs on prices despite geopolitical risks.
- European Natural Gas Prices (TTF)²
-
Strategic Importance: European gas benchmark, determines electricity and industrial production costs, indicator of continental energy security.
Weekly Data: TTF at €31.79/MWh on September 3 (-10.77% year-on-year), EU import price at $11.62/MMBtu in July (-6.04% month-on-month).
Analysis: The decline reflects LNG imports over 50% higher and well-filled storage. Discussions on complete Russian gas ban by 2027 create structural uncertainty for European supply.
- Renewable Energy Investments³
-
Strategic Importance: Indicator of energy transition speed, reveals capital allocation trends and sectoral competitiveness.
Weekly Data: $386 billion invested in H1 2025 (+10% vs H1 2024), offshore wind: $39 billion (vs $31 billion for full 2024).
Analysis: Offshore wind becomes the new investment driver while utility solar declines (-19%). This reallocation demonstrates sector maturation favoring project quality over volume.
- Energy Storage Costs⁴
-
Strategic Importance: Critical infrastructure for integrating intermittent renewables, determines economic viability of electrical transition.
Weekly Data: 2025 average costs: $200-400/kWh, residential installations: $6,000-23,000 complete, continuous decline since 2022 ($1,000/kWh).
Analysis: Falling costs (divided by 2.5 since 2022) accelerate massive deployment. The UK (+427 MW in August) illustrates this dynamic transforming global electrical grids.
- Green Hydrogen Prices⁵
-
Strategic Importance: Key energy vector for industrial and heavy transport decarbonization, indicator of electrolyzer technological maturity.
Weekly Data: Q2 2025 range: $3,865/tonne (US) to $6,260/tonne (UAE), 2030 target: $1,000/tonne for competitiveness.
Analysis: Major regional disparities reflect access to cheap renewables and electrolysis infrastructure. Expected decline in late 2025 depends on equipment cost reduction and government incentives.
- Voluntary Carbon Market⁶
-
Strategic Importance: Decarbonization financing mechanism, reveals corporate demand for climate solutions and evolution toward quality.
Weekly Data: H1 2025 credit retirements: 95 million (+9% vs H1 2024), value +32%, Q2 issuances: 77 million (+39% vs Q1).
Analysis: Value growth (+32%) exceeding volume (+9%) confirms market quality upgrade. Emergence of carbon removal credits and reinforced integrity standards are redefining corporate demand.
