Concrete manufacture is responsible for 8% of global carbon emissions, with the ingredient “clinker” accounting for most of it. Global demand for cement (which hardens into concrete) is expected to ...

To triple global renewable energy capacity by 2030 while maintaining electricity security, energy storage needs to increase six-times. To facilitate the rapid uptake of new solar PV and wind, global ...

Aluminium + air = power Al-air batteries are an inexpensive, light and powerful source of energy. The formula is quite simple: aluminium + air = power. A reaction of oxygen and aluminium in the air ...

For natural gas, it is assumed in the power price scenarios that the European natural gas price will be based on the global market price for LNG in the medium term. As the most important import source ...

We need to understand carbon capture, storage and utilisation (CCUS) better. To do so, this article looks at 10 methods and estimates how much CO2 each will take out of the atmosphere by 2050, and the ...

A new report by RMI says batteries are on the path to replace 175 EJ of fossil fuel demand in the power sector, 86 EJ of fossil fuels from road transport and can put at risk another 23 EJ from ...

Anaerobic digesters are used to turn cow manure into useable methane fuel. But the raw cost of that gas is ten times the market price. On the plus side, emissions are being avoided. So how do you ...

Financing the new hydrogen economy is already a challenge. Financing hydrogen production in Emerging Markets and Developing Countries (EMDC) is an even bigger one, yet vitally important for supplying ...

V2G (vehicle-to-grid) technology allows parked EVs to store and/or inject electricity into the grid when needed. The main benefit is to avoid the expense and disruption of building dedicated ...

In the IEA scenario where the world manages to reach net zero emissions by 2050, the average person born in the 1950s would emit 350 tonnes of CO2 over their lifetime. Babies born in the 2020s would ...

What about actual share of GDP? Assessing the extent to which different sectors of the clean energy economy contribute to GDP growth from year to year helps show the direction of travel. Yet looking ...
