It sounds too good to be true. A Swedish company, HydroInfra Technologies, claims it has invented a "hydrogen-nano gas" that neutralizes carbon dioxide emissions.
Most things that sound too good to be true turn out to be exactly that. So, hydrogen-nano gas may be fiction and not fact.
But I am hoping that this hydrogen-nano gas is fact or some other economic means of sequestering carbon dioxide can be developed in the next decade. Without an effective way of sequestering carbon sequestration, stopping concentrations of carbon dioxide from reaching a dangerous 500 parts per million is probably impossible.
