Julian Hartmann reports on energy storage innovations and the modernization of global power grids. He focuses on battery technologies, green hydrogen, and system stability.
julian.hartmann@theenergybrief.orgThe 2025 annual report of the UK Climate Change Committee shows that UK emissions have fallen by 50.4% compared with 1990, but future emission reductions will depend on electrification, making the adjustment of electricity policy costs crucial.
In-depth analysis of next-generation energy storage technologies: How emerging routes such as solid-state batteries, flow batteries, and sodium-ion batteries address grid-scale energy storage challenges, as well as the key bottlenecks facing large-scale deployment.
Global green industrial policies are reshaping supply chain layouts, from clean manufacturing to critical minerals, presenting new opportunities and challenges for the energy transition.
The global green hydrogen market is expected to grow from USD 12.31 billion in 2025 to USD 231.32 billion by 2035, at a compound annual growth rate of 34.09%.
Global energy transition and ESG financing standards are reshaping mining investment in Africa. This article analyzes how capital will shift toward sustainable mineral development in 2026, and the far-reaching impact this will have on critical mineral supply chains and the clean energy transition.
Global natural capital investment reached $61.4 billion over the past decade, with Australia attracting $6.3 billion of that, making it a popular destination. Policy stability, land scale, and carbon market opportunities drove capital inflows, but controversies over "greenwashing" also emerged.
Three major utility companies in Massachusetts have signed long-term contracts with developers for three large-scale energy storage projects, with a total capacity of 1,068 MW/4,472 MWh, marking an important step for the state toward its 5 GW energy storage goal.
Deloitte's 2026 Renewable Energy Industry Outlook points out that against the backdrop of policy changes, the industry focus is shifting to infrastructure construction and project execution, and market participants need to cope with uncertainties in incentive policies and supply chain challenges.
RETC 2026 PV Module Index shows that, as U.S. and global solar PV installations continue to expand, the industry’s focus is shifting from simply pursuing scale toward long-term reliability, supply chain traceability, and project risk management.
Based on the ECIU report “The race for net zero,” this article analyzes how the scale, industrial structure, and investment pipeline of the UK net-zero economy reflect deep changes in the energy system, and discusses their impact on the power grid, energy storage, industrial competitiveness, and policy stability.
