Impact of carbon dioxide leakage through North Sea wells

Realistic estimates show that global warming can only be kept below 1.5 or two degrees Celsius if carbon dioxide is actively removed from the atmosphere. Storage beneath the seafloor is an option that has been investigated ...

New material captures carbon at half the energy cost

UC Berkeley chemists have made a major leap forward in carbon-capture technology with a material that can efficiently remove carbon from the ambient air of a submarine as readily as from the polluted emissions of a coal-fired ...

Unforeseen dioxin formation in waste incineration

Dioxins forms faster, at lower temperatures and under other conditions than previously thought. This may affect how we in the future construct sampling equipment, flue gas filtering systems for waste incineration and how ...

Steam of hot flue gases saves energy at steel mills

A new solution from Siemens takes advantage of hot flue gases from arc furnaces to generate steam. This steam can then be used for other steel mill processes or for generating electricity. In the past, flue gases were usually ...

Researchers set out path for global warming reversal

Bioenergy with carbon capture and storage (BECCS) can reverse the global warming trend and push temperatures back below the global target of 2°C above pre-industrial levels, even if current policies fail and we initially ...
