Cable Diagnostic in MV Underground Cable Networks
Introduction
As an introduction we want to show how cable testing and diagnostics allow you to plan the maintenance of cable routes, thus preventing expensive power failures and significantly reducing maintenance costs for cable networks. We also list tried-and-tested measurement methods, describe these in detail and introduce various options for their use. Finally, we provide guidance on how to successfully implement diagnostics.

Emissions Trading Worldwide
Another eventful year has passed, and the urgency of addressing the climate crisis looms larger than ever before. Record high temperatures, extreme weather events, and other growing impacts serve as frequent reminders that the climate challenge is with us now: it can no longer be treated as a problem for the future. We find ourselves moving ever closer to the milestone years of 2030 and 2050, when many countries have set emissions reduction goals. Reaching these goals demands swifter and more ambitious action than ever. Analyses have shown that, in this critical
decade, we must strengthen domestic and international policy frameworks to dramatically accelerate our efforts to address climate change. We also know some amount of climate change is already incorporated into our future. But there is still time to avoid the worst impacts if we act with all the tools we have, including emissions trading.

Green Hydrogen Strategy
Roughly 100 years ago, in February 1923, futurist John Haldane delivered a lecture at Cambridge University on
wind farms that would provide England with clean and cheap electricity to produce hydrogen; he also envisioned
the use of underground hydrogen storage to supply energy when the wind was not available (Haldane, 1923).
Since then, there have been several attempts (for example, during the oil crisis of the 1970s) to scale up hydrogen,
particularly as a clean fuel to replace oil. Each occurrence of a “hydrogen wave of interest” marked a distinct
phase in the exploration and development of hydrogen as a viable energy solution.
The most recent phase is linked to international efforts to avert dangerous climate change. Countries around the
world agreed in 2015 that rapid decarbonisation is needed and adopted the historic Paris Agreement. According
to the Intergovernmental Panel on Climate Change (IPCC), human activities have unequivocally caused global
warming, and in the last decade the average global surface temperature reached 1.1 degrees Celsius (°C) above
pre-industrial levels. Based on the findings of Working Group III of the IPCC’s Sixth Assessment Report, global
temperature is likely to exceed 1.5°C of pre-industrial levels this century, based on current global targets expressed
in National Determined Contributions (NDC), and even limiting warming to below 2°C would rely on a rapid
acceleration of mitigation efforts after 2030.

Variable Renewable Energy Grid Integration Studies: a Guidebook for Practitioners
Countries around the world are establishing ambitious goals to scale up the contribution of renewable energy (RE) toward meeting national energy demand. Because RE resources such as wind and solar generally increase variability and uncertainty associated with power system operations, reaching high penetrations of these resources on the grid requires an evolution in power system planning and operation. To plan for this evolution, power system stakeholders can undertake a grid integration study. A grid integration study is a comprehensive examination of the challenges and potential solutions associated with integrating significant variable RE generation in the electricity grid.
