Sustainability in transformers: A key concept in a more sustainable power grid

Recently a commission of scientists and environmentalists from the European Union have declared an ambitious plan to mitigate global warming by requiring a reduction of greenhouse gas (GHG) emissions of at least 55% by 2030. The aim is to achieve climate neutrality by 2050 and avoid severe consequences of climate change [1]. Energy sustainability is now a key global imperative, and EconiQ™ transformers are suitable as a solution. Hitachi Energy is delivering to support sustainable development in power grids. The four cornerstones of the framework are carbon footprint reduction, protection of local ecosystems, improved safety, and responsible use of resources. These cornerstones are based on transparency throughout the value chain and product lifecycle, co-creation with our customers, the joint application of advanced technologies and solutions, and Hitachi Energy’s sustainability strategy for the coming years. In more detail, the application of optimal design evaluation methodologies that minimize energy consumption for operation, considering the application of high-performance and environmentally friendly materials, applying more robust technologies that minimize the severity of catastrophic events, and a detailed analysis/evaluation process provide the applicable context for EconiQ™ transformers showing some cases for a local market. This framework shows the structure and wants to provide feedback/sensitization on a suitable scenario for the conception, acquisition, and management of assets that aim at mitigating the emission of carbon polluting gases and other gases with highly damaging footprints and seek a better sustainability of the electricity sector.
