spudfan Posted January 17 Share Posted January 17 This is an interesting piece on the new "green" hydrogen power for locomtives. How "green" is the production of the new "green "fuel? Both are very good reads. Traction Technology: Are hydrogen locomotives the next big thing?

irishrailways52 Posted January 22 Share Posted January 22 interesting indeed. I often wonder how good electric is as well. would it be worth wile for Irish rail to build some sort of a wind farm or a hydro station for future network electrification 1 Quote Link to comment Share on other sites More sharing options...

If they could tap the guff coming out of Daíl Eireann, I'd say they'd have an inexhaustible supply of wind. 5 Quote Link to comment Share on other sites More sharing options...

Noel Posted February 3 Share Posted February 3 Beware Hydrogen does not necessarily mean HFC. There's green hydrogen and there's real green hydrogen. Beware, for big oil some forms of hydrogen are really just hydrocarbons by the back door. True green hydrogen is produced exclsuively from non-fossil electricity generation (ie wind/hydro/solar/pumped storage). The amount of energy it takes to produce hydrogen is massive and today mainly oil based, and the distribution costs are not alone high, but relay on fossil distribution, while every home already has a 3pin socket connected to the electricity grid which is the most efficient and economically viable energy distribution method. IMHO HFCEV tech may have a large role to play in HGVs, heavy agri, heavy construction and Hydrogen a role in grid storage and grid peaking, but doesn't make the cut for personal mobility (ie car transport). Today there are only 5 H pumps in the entire UK, and zero in Ireland, but the electricity grid in both countries already exists to every home. Ireland is ideally positioned to have a 100% green grid within 10 years (ie true green rather than green washed), and so rail transport could switch to electric. EU won't allow diesel much longer anyway. Hydrogen ICE is still combustion and generates CO2, its cleaner but no where near as clean nor efficient as our electric. Hydrogen ICE still means high maintenance costs and oil lubes, as it's basically still a mechanical combustion engine. A 201 has been trailed with this, an improvement over straight diesel with its fifty NoX emissions, but its still combustion and emits CO2. Have we run out of time for gradual managed transition? 1 1 Quote Link to comment Share on other sites More sharing options...
Broithe Posted February 3 Share Posted February 3 4 hours ago, Noel said: its still combustion and emits CO2. There shouldn't be much carbon available, mostly just some from the lubrication. CO and CO₂ emissions should be fairly low, surely? The carbon in the air will be mostly CO₂ already. Quote Link to comment Share on other sites More sharing options...

Given how little freight and passengers are conveyed by Irish Rail I wonder if this would make any significant impact other then to tick some boxes On 22/1/2024 at 2:50 PM, irishrailways52 said: interesting indeed.

Have any fossil fuel powered generator station in Ireland been eliminated by green energy from, wind, tide/hydro dare I ask? 1 Quote Link to comment Share on other sites More sharing options...
