The key role of heat to decarbonize the industrial system

Thermal storage systems can contribute to increasing the share of Green Heat. MGTES applications: Heat to Heat and/or Power to Heat

Green Heat Storage is one of the key to fight climate change. Industrial heat constitutes for most of the industrial energy request and most of direct industrial CO2 emitted every year.

One of the latest analyses on the subject goes back to the International Energy Agency's (IEA) World Energy Outlook 2017, which points out that industrial heat accounts for two-thirds of industrial energy demand and almost one-fifth of global energy consumption. And that as industrial heat demand continues to grow, so does its share of CO2 emissions, accounting for a quarter of global emissions by 2040.

On the basis of these data, it is on Green Heat that we shall bet on to combat climate change and implement the energy transition. But industrial heat is often missing from energy analyses, regulations and policies. Also the Cop26 deal makes no mention of the importance of green heat.

Among the first technologies that can contribute to increasing the share of Green Heat are Thermal Storage systems, accompanied by renewable energy installations such as photovoltaics and wind power. 

More specifically, MGTES - Magaldi Green Thermal Energy Storage (https://www.magaldigreenenergy.com/en/applications/green-heat-production), delivers Heat to Heat and/or Power to Heat, useful for different applications and market segments including the industrial sector, district heating and so on.

For these applications, MGTES is able to contribute to the flexibilisation of the electricity grid and to absorb the surplus of electricity generated by renewable energy plants, convert this surplus into heat through electrical resistances, release the heat when necessary and convert it back into electricity.

Combined with renewable energy, MGTES can generate constant green heat and contribute to replace traditional fossil fuel generation. Thus, MGTES will dramatically help to reduce CO2 emissions.

Franco Donatini, Professor at the University of Pisa, explains in an interview published in the Magaldi Green Energy blog (https://www.magaldigreenenergy.com/en/franco-donatini-green-heat-crucial-combat-climate-change), that MGTES in addition to offering “considerable efficiency, flexybility and security, with low costs that make it competitive on a large scale and has high capacities”, it projects Magaldi Group towards levels of attention to the ESG (Environmental, Social and Governance) philosophy “always higher”.

MGTES – said Donatini – “uses sand as a storage material, a clean material perfectly compatible with the environment, as well as steel plant structures, it is free of polluting materials and totally recyclable at the end of life. Technological sustainability due to the absence of special elements that are of limited availability in the underground, or that request in the costruction, disposal or recycling phase complex and energy-expensive processes”.

Let's learn more about MGTES, the new thermal energy storage technology patented by Magaldi Green Energy

11 May 2022

di Raffaello Magaldi, Executive Vice President of Magaldi Green Energy Let's learn more about MGTES, the new thermal energy storage technology patented by Magaldi Green Energy, startup of Magaldi Power aimed to pilot innovations to support energy transition for flexibilization and decarbonization of industrial processes. Magaldi Green Thermal Energy Storage (MGTES) is a flexible, high temperature Thermal Energy Storage (TES) technology for short as well as Long Duration Energy Storage. The system uses electricity for the charging phase and subsequently release energy in the form of heat when needed. MGTES is designed to offer support to renewable energy systems such as wind and solar photovoltaics, representing a sort of energy dispenser “on demand”, accumulating green energy and releasing it when needed, avoiding intermittency.

The challenge of a clean and sustainable future is possible, but it requires courage. Italy has already shown it: we can do it.

01 April 2022

di Cecile De Mauleon, Institutional Relations & Communications Manager of Magaldi Green Energy Social responsibility and awareness of sustainability will be essential to achieve the ecological and energy transition especially in light of current geopolitical and structural conflicts. Government, companies, banks, civil society are called to assume a true collective commitment with a community vision for the good of humanity and our planet. In 2020, a period of great challenges for humanity began, characterized mainly by the Covid-19 pandemic that hit all the countries of the world hard, resulting today in 472,816,657 infections and 6,099,380 deaths globally (WHO, 2022), without distinguishing between industrialized or developing countries or between poor and rich people. The high number of cases translated into unsustainable pressure on health systems and a very high level of exhaustion for health operators. This notably sensitized the world about the importance of investing in infrastructure, modernization, training, and mostly enabling working conditions for the health sector.

Cop26, focus on innovation and storage tech. Renewables energy are not enough

22 December 2021

Reduced Greenhouse-gas emissions and carbon dioxide emissions by 45% from 2010 levels by 2030 for global warming to be maintained at 1.5 °C above pre-industrial levels; zero net emissions by mid-century; drastically cutting other greenhouse-gas (methane and nitrous oxide) and new decarbonisation goals by the end of 2022. And again: to accelerate the installation of renewable energy plants and to reduction of coal-fired power stations and subsidies to fossil fuels. These are the key points of the final 11-page document, called the Glasgow Climate Pact, signed by almost 200 countries, which mark the path to combat climate change for the coming decades.
