Power plants on natural gas generate approx. 45% of the CO2 of coal.
I have generally understood that gas generates approximately half the CO2 of coal per unit of energy produced. Does that sound about right?

The Lightyear One is a solar-powered car with an eye-watering price
Ever wanted to own an electric car that can charge itself? Soon, that could be a very real possibility. Dutch clean mobility company Lightyear today debuted its long-range prototype, the Lightyear One, with a range of 725 km (450 miles) and a small battery that can be charged directly via...www.engadget.com
They talk about charging once per summer. And in this climate...a normal electric vehicle must be charged. This also partly applies to a solar car, but due to its solar cells, such a model can also 'charge' itself.
The problem with hydrogen is that you need a lot of energy to make it. And obviously it doesn’t make any sense if that is not from green electricity. (So for instance wind turbines or solar parks …..
Only Japan and companies like Toyota and Honda still seem to believe in the technology for passenger cars.
Similar things could be said about going to electric cars at this point. A big majority of the elecricity is coming from fossil fuels. We are moving one issue to a different location instead of solving the problem.All very nice, but the ship is powered by a diesel engine which consumes -in the return trip Australia-Japan)- more energy than it contains in hydrogen. And don't forget the emission of CO2. Obviously that’s not the way to go.

I suggest converting coal plants to trash burning generation. I have promoted this here since I arrived. Evidently there are a few small trash burning operations here but nothing to be too excited about.

I never said that hydogen was viable. How did I commit to whataboutism? The point I was making is that we currently don't have a solution for the problems with fossil fuels (be it hydrogen, electric or anything on the horizon). We just move the problem from one place to another. Hydrogen and electic cars are facing some of same hurdles.Renewables made up 19.8% of electricity generation in 2020, with hydro and wind making up the majority. That's expected to rise to 35% by 2030. Many countries are doing better but others much worse. So obviously that needs to go faster.
But you commit yourself to whataboutism. Hydrogen is not viable in small cars, it makes no sense even if the electricity would be 100% green. You need quite a lot of kilo (they don’t measure in liters) of hydrogen to fill a tank in a car and get a reasonable mileage. The production and transport and storage of hydrogen is very expensive (four times more than gasoline). A fuel cell is not very efficient, you don’t get a lot of bang for the buck. And currently the life of a fuel cell is not expected to be much more than 150.000 km.
If you have a huge truck or ship that could be different; they have the space for the tanks, they would become extremely heavy with all the batteries to be able to travel more than 1.000 km, and the charging of batteries would take too long.

On the solar car (company) Lightyear; it seems the first model the 0, was just too expensive and complicated to build (in Finland). The sales price of €250.000 would not even cover is.
Now it was announced that Lightyear had applied for a deferment of payment for its operational branch: Atlas Technologies. That was, among other things, the department where Lightyear had housed its production. Lightyear now announces that the Court has declared its operational branch bankrupt. Something important: Atlas Technologies B.V. is not the company that owns Lightyear's intellectual property. That is in the hands of Atlas Technologies Holding B.V.. This holding is said to house the investments of the Dutch government fund and the Swedish Koenigsegg.
Lightyear states it regrets the news - how could it be otherwise - for employees, customers, investors and suppliers. The manufacturer says it will work closely with the appointed curator.
What will the future of Lightyear look like? That is still unclear but Lightyear says they will focus on another model, the 2.
Because after the 0, Lightyear wanted to build the 2. With an expected price tag of less than €40,000, this is a much more affordable 'solar car', for which 40,000 private individuals have already signed up. Companies such as LeasePlan and MyWheels have already (pre)ordered more than 20,000.

This would be a huge jump since 10-20% improvements are newsworthy. It appears another company beat them to the 500 number a month ago, but making a test unit versus an economically viable production battery is a different matter, the first to do that will sell very well. And maybe make our smartphones last several days as well.twice the energy density of a modern lithium-ion battery
Let’s see what Indonesia is doing to create green energy. There are 11 geothermal** and 30 hydro-electric* power plants but currently they predominantly use power stations on fossil fuels (as coal) and biofuels. Now they’re very proud of their biodiesel but if you consider what that is, made from vegetable oil or animal fat, it is not positive at all. It is never good to use (land destined or suitable for) food production -think of soy bean, sun flower, peanut and coconut oil- for fuel production. Not to speak of the very controversial palm oil production in the country. There are currently 18 power plants under construction which would mainly burn coal. Oops.
