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 ...

Russia’s invasion of Ukraine resulted in the EU and the US quickly imposing sanctions on imports of Russian oil and gas. But sanctions on Russia’s nuclear exports have been far lighter because ...

Sodium-ion (Na-ion) batteries, a much more abundant and cheaper alternative to the standard Lithium-ion, are on the verge of commercialisation, explain Carlos Ruiz, Martina Lyons, Isaac Elizondo ...

Small Modular Reactors (SMRs) are being presented as the next generation of nuclear technology. While traditional plants face cost overruns and safety issues, SMRs are seen by their champions as ...

Universities worldwide still produce more workers for fossil fuels than for renewable energy industries. Roman Vakulchuk and Indra Overland at the Norwegian Institute of International Affairs ...

In X-Change: The Race to the Top, RMI looks at the contest between China, Europe, and the United States to make and deploy the energy technologies of the future. China is in the lead in many of the ...

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 creates electricity and ...

UCO (Used Cooking Oil) is a feedstock for biofuels. In 2023, European countries consumed close to seven million tonnes of UCO for biofuels. This is four times the continent’s maximum potential for ...

Sustainable sources of carbon have to be short-cycle, meaning that the carbon was taken from the atmosphere either indirectly through photosynthetic plants (biomass) or directly using direct air ...

Battery storage in the power sector was the fastest growing energy technology in 2023 that was commercially available, with deployment more than doubling year-on-year. Lithium-ion batteries dominate ...

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 ...

Green hydrogen is set to transform the steel industry. Hydrogen-based direct reduction (DR) technology is already leaving behind other decarbonisation solutions for primary steelmaking such as carbon ...
