Scaling up the production of what we call green hydrogen is a priority for researchers around the world because it offers a carbon-free way to store electricity from any source. Green hydrogen is a carbon-free method that uses an electrolyzer to split water into hydrogen and oxygen gas. Choubisa et al.

The researchers conducted ecosystem-scale comparisons of carbon, nitrogen, water, and energy fluxes of Sorghum bicolor with maize and Miscanthus x. The fluxes reflect “the breathing of the ecosystem”—how water, carbon dioxide (CO 2 ), nitrogen (N), and energy move between plants and the atmosphere, Moore said.

A paper by a team from the University of Chicago and MIT suggests that technology-driven cost reductions in fossil fuels will lead to the continued use of fossil fuels—oil, gas, and coal—unless governments pass new taxes on carbon emissions. We need both a policy like a carbon tax and to put more R&D money into renewables.
