Very interesting - I too had assumed that green hydrogen was potentially the answer for heavy trucks/busses/plant machinery. Now maybe not, simply because logistics and costs will rule it out when compared to battery.
And you can totally forget it with regards to domestic heating versus heat pumps for same reason. It's not even going to be the solution for heavy shipping. Looks like there is no viable 'solution' to that, just hybrid methods like wind-assist to help reduce the carbon output whilst still using heavy oil. Like the prof. says, there's no perfect solution, but some solutions are clearly better (more viable) than others. |

Romours of a shoebox size nuclear power plant are interesting. 28 years or 250k of vehicle power supply while using used plutonium. Ride like you stole it!!

I’ve just had an email “discussion” with my electricity supplier about why I’m paying for oil and gas price hikes when they only make electricity from renewables………….. their claims are true but the charges are incurred, they claim, when they sell that electricity to the national grid……….
They export 100% “green” generated electricity but that becomes what they call “brown” or “dirty” electricity as soon as it’s sold to NG and is mixed with electricity generated from oil and gas. There is a move now to detach the charges for using renewables generated electricity from their link to “brown” electricity but guess what? The big suppliers of dirty generated electricity are resisting that fiercely as their business with disappear if the consumers all switch to renewables generated cheaper power supplies!

Now gone - old faithful, no mechanical issues whatsoever ever but the leaks and rattles all over the place won’t be missed! |

I think the future for hydrogen is more likely as a store of excess energy generated from solar/wind. Will depend upon the relative costs of lithium batteries vs hydrogen storage and generation.

Ground source heat pumps are super hungry when it comes to electricity. Ours makes up 2/3rds of our monthly electricity usage  Only found this out when the darned thing died in August. 
The un-told nasty with regards to GSH is that there aren't enough techs to service and fix the darned things either. Been on a waiting list for two months now. The other thing is that we do not produce enough energy from renewable sources to supply everyone so even if everyone switched to companies supplying only from renewable sources you'd never actually receive electricity from those sources because there is not enough to go around. Having spent the last 8 years working in the marine renewable sector and I can also say that whilst the talk is about offshore energy and isn't it marvellous the amount of red tape and actual lack of governmental support is laughable. Just enough to make it look like they are doing something but no modern government is going to sign on to a 50-100-150 year building project (as with some of the tidal lagoons) even if it is the answer. All too afraid of yet another HS2 or NHS overspend debacle. There are some great projects out there but I doubt they will ever get off the ground, too many reasons, fears, anti-change sentiments that will prevent us taking the leap. No I think it is going to take a government like we have never seen before to push the UK anywhere near the green targets some bod in a committee meeting set for the EU. In the meantime all we can do is keep our Defenders going  |
