@hente_afsc There were some Norwegian guys yesterday at the Gunners who paid 200 £ for the Fulham tickets and my friend could only get a club level seat for 100 $ so I suppose it's true

[Eero Vartiainen @EAVgooner]

@hente_afsc I was just about to ask a pub question: who scored a hat-trick at Filbert Street 25 yrs ago, but you already know it. Saw it on the wall inside the stadium entrance.

[Eero Vartiainen @EAVgooner]

@hente_afsc I have to admit that I cheated and googled if Juan played any games.

[Eero Vartiainen @EAVgooner]

@hente_afsc Ok, then it must have been Juan at 3 and the Beast 5

Thread: Version 1.2 of The #Arsenal history in Woolwich & Plumstead. I've added pictures, addresses & updated some info of the places.

Here we go, Map & info: 1/5

[Eero Vartiainen @EAVgooner]

@hente_afsc Wonderful work again Hente! The map and guide is now very handy for Gooner Pilgrims!

[Eero Vartiainen @EAVgooner]

@hente_afsc @Gooner_AK @RoyalArsenalMRA Sorry, I meant of course 395 West Ferry Road.

Solar hydrogen disrupts H2 supply #ETIPPV @EAVgooner: https://t.co/3LNUp6Fbpi. Findings: Solar-H2 already today in cost parity to fossil-H2 at best sites. Fossil-CCS H2 is disrupted right now. @mzjacobson @JeroAhola @kei_sakurai @CKemfert @BrianVad @EWGnetwork @efesce @nworbmot

Onsite hybrid PV-Wind plants can harvest specific benefits, researched @UniLUT @RL_Institut Solarpraxis @phdsun : https://t.co/OYia35xTif Key benefits: shared grid connection capacities, excellent area utilisation, permit & O&M synergies. @c_gerhards @mzjacobson @ProfStrachan

Cost of #solarpower again below #electricity market prices. Updated factsheet on PV LCOE by ETIP PV: https://t.co/sU6XrFAQ50

[Christian Breyer 🦣 @ChristianOnRE]

Italian homeowners can now install PV systems for free https://t.co/C7J5Ns9pa6 - great move in Italy to combine COVID-19 recovery and climate mitigation measures. Excellent PV economics in Italy will boost the transition https://t.co/3oqvBfWbU2

[Eero Vartiainen @EAVgooner]

@VTulkki @JeroAhola @Fortum Thanks for the information. I agree that LCOE is not the only point, it also matters with what the hydrogen is made.

[Eero Vartiainen @EAVgooner]

Please read my post about #Hydrogen Economy on #ForTheDoersBlog @Fortum, hydrogen produced with #solarpower and wind will be one cornerstone of the future energy system. https://t.co/ZBHotGbvVp

[Eero Vartiainen @EAVgooner]

@VTulkki @JeroAhola @Fortum I am not aware of such plans. I think that nuclear power may find it difficult to compete with the price of solar and wind as an electricity source for electrolysis. Currently, PV LCOE is 15-40 €/MWh depending on location and decreasing to 6-15 €/MWh by 2050 (see figure below).

@ddiazpilas @anunezjimenez @ChristianOnRE @BecquerelForPV @Daverik80 @pirrosky Sure, electrolyser effiency 67%, CAPEX 2020/30/50 170/115/80 €/kW, OPEX 2.5% of CAPEX (apart from electricity), utilisation same as for fixed-tilted yield for PV, i.e. from about 1000 h in Helsinki to 2600 h in Chile, lifetime 30 years (30 000 - 80 000 h)
