Japanese scientist uses egg white for clean energy

you must be yoking, boom boom.

What is white, but not white?

nanda - "Shaun the Red".

PBS Newshour famously jumped at the chance to run a segment about an invention to generate hydrogen from water via low-energy catalytic process. The embarrassment of the hoax was so bad that all trace of that segment was taken off the PBS site. A transcript of the segment has been preserved: https://teslamotorsclub.com/tmc/threads/pbs-newshour-science-water-to-power.83221/

Hydrogen has been "on the verge" of making it big in the energy sector for many decades, but still cannot compete with solar, hydro, geothermal, or wind. With solar panels now in the 20% efficiency range, they are becoming cheaper than natural gas for making electricity.

the production of carbon-free energy -- by using proteins taken from egg white.

April Fool in advance ? Nothing is more carbon wasting than the production of eggs.

"... but still cannot compete with solar, hydro, geothermal, or wind."

Hydrogen doesn't compete with solar, etc., which are means of harnessing / extracting energy. Hydrogen is a means of storing / transporting energy to where it is needed. You can use solar or wind energy to produce the hydrogen to fill canisters that can then slot into, say, forklifts working underground or in warehouses where emissions would otherwise be a problem.

Solar, wind, and other means of harnessing energy require storage. Current storage (battery) systems have a lot of pitfalls and limitations and there is a lot of work to be done. Hydrogen can easily be part of the whole complex mix that helps us toward clean, sustainable energy.

What I really came here to say is that I find it hard to see the words "clean" and "chicken" in the same sentence. I hate those evil, dirty birds. (Cheers to the scientists all the same.)
