Tackling climate change with blue hydrogen

[thomas]

The BBC on Japanese plans to construct 22 (!) new coal-fired power stations and on generating clean (but expensive) power with blue and green hydrogen.

Where is the hydrogen to power Japan zero-carbon society going to come from? The answer is "blue hydrogen". Make hydrogen from water using renewable energy and you get "green hydrogen". The problem is green hydrogen is really expensive. Instead, today most hydrogen is made from natural gas or even coal. That is cheap but it produces lots of greenhouse gases. However, if you capture those greenhouse gases and bury them in the ground, you are allowed to call it "blue hydrogen". This is exactly what Japan says it is going to do.

Climate change: Is ‘blue hydrogen’ Japan’s answer to coal?

The Fukushima disaster turned Japan away from nuclear. A new energy source may help it quit coal.

Blue hydrogen is the normal supply of hydrogen- as economical as it can be produced from natural gas but still produces more CO2 than just using natural gas normally. No one is going to use so called renewable energy with massive subsidies as it can't be relied on to use an industry plant constantly- plants sitting around as wind or solar energy fails is wasted capital
