Oil Markets, Grid Bottlenecks & Advanced Thermal Batteries
From changing global oil markets and rising transport costs to the growing pressure on electricity grids, the energy system faces a mix of challenges and opportunities. Thermal batteries are moving into commercial use, while new forecasts highlight the continued gap between fossil fuel trends and climate goals.
🌍 ExxonMobil Outlook Points to 2.5–3°C Warming
ExxonMobil’s latest outlook projects energy-related CO₂ emissions falling by 2050, but remaining well above levels associated with limiting warming to 2°C. It also expects strong electricity growth and continued oil demand, highlighting the gap between current trends and climate targets.
🛢️ Supertanker Shortage Pushes Up Oil Transport Costs
A shortage of large oil tankers is increasing the cost of transporting crude worldwide. Shipping oil from Houston to Asia now adds around $26 per barrel, demonstrating how shipping capacity can influence global energy prices.
⚡ Grid Bottlenecks Threaten Clean Energy Growth
Around 2,500 GW of wind and solar projects are reportedly waiting for grid connections. Expanding transmission networks, energy storage and system flexibility will be essential to integrate renewable power while maintaining reliable and affordable electricity.
🔥 Thermal Batteries Move Into Commercial Use
Thermal energy storage is moving beyond the development stage, with around 80 projects worldwide and 51 already operating. Most systems range from 1–100 MWh, while larger projects demonstrate the potential for storing substantial amounts of energy as heat.
🌍 How the US Reduced Its Reliance on OPEC Oil
US crude oil imports from OPEC fell 84% between 2008 and 2025, while domestic production and Canadian supplies grew. By 2025, Canada supplied more than 4.5 times the crude imported from OPEC, reshaping America’s oil supply network.
