There is already a lot going into green hydrogen, that could replace a lot of fossil fuel power

Huge changes need to happen to get us back from the tipping point or slow down the fall until we can learn how to recover

My brother and I asked our dad to plant a tree to help combat climate change. We have a nice open spot in front of the house and will plant a white birch.
If more of us did this it would help take carbon dioxide out of the atmosphere. One tree doesn't sound like much, but if we all did this, obviously you'd have to have somewhere to plant one, or encouraged our family and friends to plant one I think it would have a positive effect.
What do you think?

So far biggest cost of pure hydrogen gas is not finding hydrogen or storage or transportation of it. It is cost of energy needed to make it.
We are so far having handfull of options to generate that needed power.
Solar =expensive so far
WInd =expensive so far
Fossil = Inexpensive but doesnt fix problem
Geothermal = Cheap but not available everywhere
Hydropower = Cheap but has its own problems and capacity is pretty much full already
Bio-power = works well where ever there is sawmills or other production facilities that generate more power than they consume. And works as long as forestry is sustainable.
Nuclear power =cheap and plentiful -

Hydrogen is a source of energy, you can use it in engines as a fuel for one -

It all boils down to costs. How much of energy bill you are ready to pay. -

Nuclear is very expensive.
Source: eia.gov/outlooks/aeo/assumptions/pdf/table_8.2.pdf
Solar is about 1.25 dollars per installed W, Nuclear is over 6. Maintenance costs are even higher for nuclear.
Wind is slightly more expensive than solar: 1.7 dollars.
Solar is pretty much the cheapest option.
Only coal-fired power plants are cheaper, and those have all sorts of other issues (mainly pollution, both in mining and at the power plant itself). -

But yes, hydrogen can be made with clean and cheap(-ish) energy. -
Well, that meeting happened in Glasgow, but I don't really know if it was a good agreement or not.

You can use to make electricity or replace petroleum fuel in engines -
indeed a strange view on climate change
if it's getting hotter, it's more likely we'll wear old fashion desert proofed fabrics like this
