The global freshwater model WaterGAP calculates flows and storages of water on all continents of the globe (except Antarctica ), taking into account the human influence on the natural freshwater system by water abstractions and dams. It supports understanding the freshwater situation across the world's river basins during the 20th and the 21st ...
Methanol economy. The methanol economy is a suggested future economy in which methanol and dimethyl ether replace fossil fuels as a means of energy storage, ground transportation fuel, and raw material for synthetic hydrocarbons and their products.
In this process, hydrogen is produced from a chemical reaction between steam and methane, the main component of natural gas. Producing one tonne of hydrogen through this process emits 6.6–9.3 tonnes of carbon dioxide. [ 3] When carbon capture and storage is used to remove a large fraction of these emissions, the product is known as blue hydrogen.

Hydrogen economy. Hydrogen has the most potential to reduce greenhouse gas emissions when used in chemical production, refineries, international shipping, and steelmaking [ 1] The hydrogen economy is an umbrella term for the roles hydrogen can play alongside low-carbon electricity to reduce emissions of greenhouse gases.
1819 – Edward Daniel Clarke invents the hydrogen gas blowpipe. 1820 – W. Cecil writes a letter, "On the application of hydrogen gas to produce a moving power in machinery". [6] [7] 1823 – Goldsworthy Gurney demonstrates limelight. 1823 – Döbereiner's Lamp, a lighter invented by Johann Wolfgang Döbereiner.
One reason could be that companies prefer to back projects closer to their business sites. Conversely, carbon credits with older vintages tend to be valued lower on the market. [82] Prices on the compliance market are generally higher. They vary based on geography, with EU and UK ETS credits trading at higher prices than those in the US in 2022.
