... which is considerably more expensive than solar + hydrogen.
- cubefox 3y agoHydrogen for power storage is hardly used in practice, so it is probably quite expensive. Overall, solar energy seems very expensive when you factor in storage cost. Germany has very high energy prices, likely related to switching off fission power plants and heavily investing in intermittent energy sources like wind and solar.
- Certhas 3y agoLikely related to? As in you pulled this idea from thin air and pop science reading? Electricity prices are mostly political. Fossil has been heavily subsidised throughout its lifetime, as has nuclear. French prices are lower because their energy producer has 70 billion in debts, backed by the French state, in order not to pass the true price of nuclear on to consumers. Hydrogen is not used yet, because we don't have enough renewables to have significant overproduction. For now storage is not needed. Truly this is a topic where everyone feels comfortable to throw in strong opinions without having even the slightest idea of how any of it works.
- cubefox 3y agoYes, electricity prices are political when you include disabling existing fission plants that are very cheap to operate (most of the cost comes from building them). Germany also has heavily subsidized renewable energy, but electricity prices are nonetheless so high that some major industry actually left the country.
- Certhas 3y agoSorry but bullshit. Electricity prices are made up of taxes, subsidies and everything in between. There is no causal relationship between high share of renewables and high electricity prices in Germany. If you have any argument or evidence that supports the causal link, please share. If not please acknowledge that you are operating on gut feeling without a factual basis. Wholesale prices for electricity have been higher in France than in Germany, they have been much lower in Sweden, which has more renewables than Germany in the system already.
- pfdietz 3y agoHydrogen is hardly used in practice because we are still burning fossil fuels. Why make hydrogen for storage if you're allowed to burn methane?
