Audi Hungaria starts operation of Europe’s biggest solar roof installation

Green Car Congress

The first is the switch to green power, which has taken place thanks to the commissioning of Europe’s biggest photovoltaic roof installation and the supply of electricity from renewable sources. Since 2015 the company has made use of 250 gigawatt-hours of geothermal energy, reducing emissions of CO2 by 50,000 tonnes.

IEA: global electricity demand growing faster than renewables, driving strong increase in generation from coal

Green Car Congress

Renewables are expanding quickly but not enough to satisfy a strong rebound in global electricity demand this year, resulting in a sharp rise in the use of coal power that risks pushing carbon dioxide emissions from the electricity sector to record levels next year, according to a new report from the International Energy Agency.

Rio Tinto and ARENA to study hydrogen calcination to reduce carbon emissions in alumina refining

Green Car Congress

Rio Tinto has partnered with the Australian Renewable Energy Agency (ARENA) to study whether hydrogen can replace natural gas in alumina refineries to reduce emissions. Klett and Perander (2015). In a 2017 open-access paper exploring the use of concentrated solar thermal (CST) radiation for alumina calcination, Davis et al.
