Harvesting hydrogen
As shown in Fig. S14 and video S3, the ID-TENG can effectively harvest wave energy and power water splitting to produce hydrogen. The hydrogen production rate is about 64.5 μL min −1 under the water wave condition (1.07 Hz), and the corresponding energy conversion efficiency of this system from electric energy to chemical energy is about 40. ...The fossil fuel industry, in its greenwashing efforts and to ensure continued profits from developing new fields to harvest, wants the public to buy into hydrogen produced from oil and gas. In a world turning away from the burning of fossil fuels because of climate change, hydrogen from seawater would be a breakthrough of global significance.Hydrogen Sulphide (H2S)Strip Test. H 2 S Strip test is a water quality test conducted to determine the bacterial contamination of water. The testing sample is a H 2 S strip that is available from the market. This is the initial test conducted to determine the level of bacteria in the rainwater harvested. The test involves the following steps: 1.
