#h2 #hydrogen needs to get cheaper aproximately 50% in order to be competitive #renewables #energy #bmw #toyota and others :(

Key quote on #H2 fuel cell: "EV cars can be excellent sources of flexibility for power systems. Electrolysers [..] may also provide some flexibility services. However, their need to run for as many hours as possible per year to reduce the cost of hydrogen limits this potential service. [..] In general, a large nationwide EV fleet can support the decarbonisation of the power sector, modulating the charging time to meet variable renewable energy production and providing other flexibility services"

#ship #traffic #shipment #global #climate #co2 #bigoil #energy #oil #fossilfuels it's a whee bit overwhelming X-D https://www.marinetraffic.com/en/ais/home/centerx:25.8/centery:18.7/zoom:3 #oiltanker #environment #nosmoking #renewable #h2 needs to be cheap as shit like 3 bucks per 1kg to be competitive (its possible)

Unfortunately, Alpha-Otto describes reduced "emissions" as soot and GHG.

They neglect it has taken Cummins & other biggies 5+ yrs to get marketable NOx emissions for their hydrogen #ICE engines! #H2
------
A prototype two-stroke internal combustion engine that uses a rotary exhaust valve eliminates the need for oil mixed with fuel, resulting in cleaner and more efficient combustion. It can therefore be run using natural gas, hydrogen, and biodiesel as well as gas.

There are 2 main ways to power a vehicle on land, sea or air with hydrogen:

1-hydrogen fuel cell electric vehicle #hydrogen #FCEV
2-hydrogen internal combustion engine #H2 #ICE

muss erst wieder Druck aufgebaut werden. Und es gibt nicht mehrere Säulen und weniger Tankstellen als Lademöglichkeiten. In Österreich gibt es jetzt keine mehr.

> Realisiert wird das Projekt HY.Kiel von fünf Gründungsgesellschaftern, die rund elf Millionen Euro in den Bau investiert haben.

11 Millionen für EINE Tankstelle!

Some organisms are capable of atmospheric chemosynthesis, or capturing/using 0.5ppm atmospheric hydrogen to live.↙️

↘️ Basecamp Research's biodiscovery process found a new Antarctic bacterium species that metabolizes #hydrogen!

This new bacterium is among the over 1MM new species they discovered!

Megawatt #BEV charger from #BYD might be 4x faster than Tesla's, but it's still only half as fast as refueling a hydrogen fuel cell electric vehicle.

BYD does only 47% of battery capacity in 5min, while #H2 #FCEV refueling does a 100% fill in 5min!

Egli (2025) claims green hydrogen from Africa is too expensive to export.
But since he botched electrolyzer CAPEX, how reliable is the rest?

Green #H2 projects risks actually extending fossil fuel use, as well as deepening neo-colonial extractivist practices, including the large-scale appropriation of land, water & energy in producing countries. @fadhelkaboub.bsky.social @dontgasafrica.bsky.social corporateeurope.org/en/dirty-tru...

Comparative #BEV charging vs hydrogen fuel cell charging costs:

1️⃣ US$1-8MM/mile cost for overhead catenary electrical infrastructure for electric trains/vehicles.↙️

2️⃣ Or US$6.3-6.6MM per lane-mile for on-road Dynamic Wireless Charging #DWC. ($12.6-13.2MM/mile for 1 lane in each direction)↘️

3️⃣ That pays for a lot of #H2 fuel cells & green #hydrogen refueling!
