Environmental researchers say that "greenhouse gas solution in hydrogen as an alternative to low efficiency and are the most expensive and dirty energy to clean and isn't solving the pollution problem.
Environmentalists say "In order to solve the problem of greenhouse gases. Hydrogen is an effective alternative minimum. And most expensive "and the energy being clean, dirty, does not solve the problem of pollution.
Environmentalists said "in solving the footprint. Hydrogen is the choice with low efficiency, and the most expensive "and the energy ที่สกปรก to make clean, not solve the pollution.
