It's far cheaper to distribute energy via hydrogen than it is to distribute energy via electricity, especially over long-distance: https://docs.nrel.gov/docs/fy22osti/81662.pdf

We will likely make hydrogen where it is cheap, and then distribute via pipelines or other methods to where it is needed.

PESA Bydgoszcz SA Rail Vehicles will begin work on Poland's first hydrogen-powered passenger vehicle, capable of operating on both electrified and non-electric lines. The National Fund for Environmental Protection and Water Management (NFEP) has signed an agreement with the company to co-finance the project from the National Recovery and Resilience Plan (KPO).

California has recently expanded its network of retail hydrogen stations with the soft opening of Chevron’s third hydrogen refueling station, located in Carson. This milestone reflects growing momentum in expanding California’s hydrogen fueling infrastructure to support the deployment of fuel cell electric vehicles (FCEVs) across the state’s diverse regions.

Hydrogen is increasingly viewed as a critical energy carrier capable of supporting decarbonization across sectors such as industry, transportation, and power generation. Unlike fossil fuels, hydrogen combustion produces no direct carbon dioxide emissions. However, large-scale deployment of hydrogen technologies requires reliable methods for storing vast amounts of hydrogen to balance supply and demand, particularly for seasonal energy storage.

Surface storage solutions, such as pressurized tanks, are costly and limited in capacity. For this reason, scientists are exploring underground hydrogen storage (UHS) in geological formations.

BEVs are still cars and create massive traffic problems. Cars are not guaranteed to be faster. We cannot all use cars for all of our transportation needs anyways, so alternatives need to exist regardless.

Humans burns calories all the time, even when resting. And you still need to exercise. Might as well power a real bike instead of a stationary bike. So this is a totally silly thing to worry about.

A cargo bike can go anywhere a normal car can go. An e-bike is many times more efficient than a car. The argument used in favor of EVs over ICEVs also applies to e-bikes over EVs.

I understand that it is a matter of degree. But that means accepting that the BEV is a compromise no matter what their boosters claim otherwise. And there is room for another level of compromise, where people get out of their cars and into something even greener. If people are to stay in their cars, then we might as well stop pretending to care about efficiency.

Many people need a change in lifestyle or livelihood to adapt to BEVs. It is hypocritical to claim that people can't further adapt to bikes or at least e-bikes.

Cargo bikes exist too. You can carry significant cargo with them.

Likely a metal hydride based system. It is at present the only geniuinely mature way of storing hydrogen in a solid state form.

A Norwegian startup has secured USD 17.5 million (EUR 15 million) in a Series A funding to develop a new seasonal energy storage system aimed to help homes store excess amounts of solar energy in summer for use during the winter.

Designed by Oslo-based energy storage scaleup Photoncycle, the seasonal solid-state hydrogen energy storage system is set to roll out commercially in Denmark and the Netherlands. It aims to tackle long-duration storage across seasons, one of the greatest challenges facing renewable energy systems.

Millions, sure. But that's still a niche.

It's important to note that the car itself is a luxury or extravagance. The most practical form of a car is a bicycle, which most people don't want. So inevitably, cars always become a way of showing off capacities that you don't need. Cars with any kind of deficiency get weeded out, simply because they can't show off those extra capacities. And battery cars have something like that. People will move away from them specifically they can't do things like crossing the Outback.

I did not say you can't have battery cars. It is just a limited technology and would likely shrink to a niche market without subsidies.

A British Columbia pulp mill that’s been in operation for more than 50 years will test a way to replace carbon-emitting natural gas with clean-burning ‘green’ hydrogen made from water.

The novel approach is expected to reduce the Kruger Kamloops Pulp Mill’s greenhouse gas emissions by 7,000 tonnes a year – the equivalent of removing 1,200 to 1,500 vehicles from the roads, according to Zachary Steele, chief executive of New York-based Elemental Clean Fuels, the developer behind the green hydrogen project.

Toronto-based Elemental Trucks says it has completed development of what it describes as Canada’s first commercially available 63.5-tonne hydrogen fuel-cell-electric truck, positioning the company to enter the heavy-haul, long-distance segment of the zero-emission market.

A team at Inner Mongolia Normal University has demonstrated a process that takes shredded PET plastic, dissolves it in a chemical bath, and runs an electrical current through it. What comes out the other side is hydrogen gas — a clean fuel — and a chemical called formate, which is used in animal feed and food preservation. Both have commercial value. Neither requires new raw materials beyond the waste plastic itself.

Round-trip efficiency is not that important. If it really was as important as claimed, we wouldn't be talking about cars at all. It would all be about bikes, buses, trains, walkable neighborhoods, etc., instead. But in the real world, we will need to accept less-than-perfect solutions. So as long as the idea is green, it should be tolerated.

We also have far more renewable energy available to us than we could ever hope to use. It is orders of magnitude more plentiful than fossil fuel energy. As a result, there will be an overabundance of green energy in the long run. It is fine to use that excess of energy to make stuff e-fuels or hydrogen.

Most of your claims are just climate change denial arguments. Many of them were directly made up by the fossil fuel industry.

[-] Hypx@piefed.social 1 points 4 days ago

Electricity has gotten dramatically more expensive too. It is no panacea. In all likelihood, most of transportation will shift over to either green fuels (e-fuels) or hydrogen. Those are one-to-one replacements for fossil fuels.

Opposition to hydrogen is falling for fossil fuel propaganda. It is absolutely necessary for solving climate change.

I've learned to stay away from some of the lemmy instances. They are ran by maniacs or worse.
