aThe electrical long-term heating has been designed to ensure that even on the corners and edges of the plate, the temperature remains uniform. 电子长期热化被设计保证甚而在板材的角落和边缘,温度依然是一致。 [translate] aHydrogen sulfide gas can alter the solidity of metals, thus making them ...
Driving on hydrogen and using it to heat our homes could be a solution to the climate problem. At least, if we start producing it in the right, clean way. Leiden researchers mapped out the global environmental impact of hydrogen ...
aHydrogen gas can be biologically produced at high concentration (60%) from the fermentation of high sugar substrates such as glucose and sucrose ( Van Ginkel et al., 2001 ; Logan et al., 2002). 氢气可以生物导致以高浓度(60%)由高糖基体的发酵例如葡萄糖和蔗糖(范・等Ginkel, 2001年; Logan...
A hybrid vehicle is an automobile that uses both an internal combustion engine and an electric motor to run. Hybrids are more fuel-efficient and have a smaller environmental impact than traditional vehicles, but they can cost the same as or less than comparable gas-powered cars. ...
One of the main benefits sought by including hydrogen in the alternative fuels mix is emissions reduction – eventually by 100%. However, in the near term, there is a very significant cost differential between fossil fuels and hydrogen. Hythane (a blend of hydrogen and natural gas) can act ...
Solar power faced similar challenges a decade ago. Thanks to low-cost manufacturing in China and supportive government policies, the sector has grown and is,within a very few years, expected to surpass gas-fired power plant installed capacity, globally. Green hydrogen requires a similar concerted ...
