Three different power-to-methane process chains with grid injection in two scales (1 MWel and 6 MWel) were analysed regarding their investment and operation cost. The process chains were based on biological or catalytic bubbling fluidised bed methanation i ...
Negative emissions are necessary on the path to net-zero. This short presentation shows how they contribute to climate neutrality and how that could be paid for. ...
By the century's end, many tropical seas will reach temperatures exceeding most coral species' thermal tolerance on an annual basis. The persistence of corals in these regions will, therefore, depend on their abilities to tolerate recurrent thermal stress. ...
Natural gas (NG) is a suitable alternative to gasoline and diesel fuels to decrease the carbon footprint of the mobility and energy sectors. Although NG is considered a fossil fuel, methane (CH4), its main component, can be produced industrially from power ...
CONTEXT: Crop phenology integrates information of how environmental drivers and management practices affect plant performance and crop yield. However, little is known about the impact of cropping systems (CS) on crop phenology and how this relates to diffe ...
This commentary paper from the recently formed International Global Atmospheric Chemistry (IGAC) Southern Hemisphere Working Group outlines key issues in atmospheric composition research that particularly impact the Southern Hemisphere. In this article, we ...
The countries in Western Africa have the greatest potential for renewable energy generation in the world and are likely to be vulnerable to the adverse effects of climate change. Unfortunately, only a few of them have tapped into this potential, as non-ren ...
Microbial life is widespread in the terrestrial subsurface and present down to several kilometers depth, but the energy sources that fuel metabolism in deep oligotrophic and anoxic environments remain unclear. In the deep crystalline bedrock of the Fennosc ...
Accumulation of methane in oxic waters of lakes and the ocean has been widely reported. Despite the importance for the greenhouse gas budget, mechanistic controls of such "methane paradox" remain elusive. Here, we use a combination of CH4 concentration and ...
In this paper, we propose setting up a fund to finance the removal of all Swiss territorial GHG (greenhouse gas) emissions from 2030. The fund will accelerate decarbonization and help reach annual net zero emissions around 2040, and then progressively remo ...
