🚨@vonderleyen's 1st #SOTEU
Stay tuned:
"For me it is crystal clear–we need to build a stronger European Health Union
& to start making this a reality we must now draw the 1st lessons from the health crisis
We need to make our new #EU4Health programme future proof"@SKyriakidesEU
"...this was a global crisis we need to learn the global lessons. This is why, along with Prime Minister @GiuseppeConteIT and the Italian #G20 Presidency, I will convene a Global Health Summit next year in #Italy.
This will show Europeans that our Union is there to protect all."
"...the Commission created the #SURE programme(...)This is real European solidarity in action. And it reflects the fact that in our Union the dignity of work must be sacred."💪🇪🇺🤲"will put forward a legal proposal to support Member States to set up a framework for #MinimumWages"

1/10 Tomorrow, @EU_Commission President @vonderleyen will make her 1st #SOTEU speech. The #VdLCommission’s been off to a good start with an ambitious #green agenda & the #EUGreenDeal, but the real test of her green credentials is yet to come...
2/10 Our #EU experts @manondf + @Pieter_de_Pous will be live-tweeting highlights during tomorrow’s #SOTEU speech at 9:00AM CEST.

If you’re interested in #euclimate be sure to follow along! In the meantime, here are some major areas we’ll be looking out for 🧐👇
3/10 Pressure by many including @Fridays4future and a #Green wave during last year’s @Europarl_EN elections left @vonderleyen with little alternative than to elevate the #green agenda to unprecedented prominence.

1/ Hi #energytwitter, I'm excited to share my thoughts on the changing role of #electricity #storage in the #renewable #energy transition in my new @Joule_CP Commentary! @CellPressNews 🔋

doi.org/10.1016/j.joul…

A little thread ⬇️
2/ I discuss three strands of the literature, and illustrate how the main driver for (bulk) electricity storage deployment shifts from taking up renewable surplus generation to supplying peak residual load when the renewable share increases (and what changes with sector coupling)
3/ I do so with residual load duration curves (RLDC) from a stylized #opensource model. The RL in one hour is the electric load during this hour, minus the potential generation of variable renewables. A RLDC sorts all hourly RL values of a full year in descending order🤓

Everything you want to know about hydrogen economy.

Thread 👇
1/Why bother?

Burning of fossil fuels produces CO2, a greenhouse gas emissions (GHG).

To meet Paris agreement goals, countries are looking at ways to reduce carbon footprints.

Hydrogen stands out as a clean fuel!

Burning hydrogen produces water.

H2 + 0.5 O2 --> H2O
The (hot) combustion energy can be converted to electricity.

OR

You can use a fuel cell to combine oxygen and hydrogen to form water with production of electricity.

1/ Finally got around to listening to @TESLAcharts's excellent pod with @nikolatrevor. I'll give broad-brush commentary; others like @BonaireVolt have probed specifics.
1a/ On BEV vs FCEV @JigarShahDC put it best on @TheEnergyGang (22-25 minute mark)
"The use of math all the time to say #fuelcells are worse than batteries literally makes no sense. This is not about round-trip efficiency..."
FRAME THIS STATEMENT! greentechmedia.com/articles/read/…
2/ Shah explains it's about culture change. Milton speaks from the heart as a guy who dropped out of college, and had that taunt lobbed at him a lot. Seriously, WHO BETTER TO WIN OVER TRUCKERS?? Bring an I-know-better MBA or MSc attitude in and you'll be tossed to the curb.

If we want to become the first climate neutral continent by 2050, we need to switch our energy systems from fossil fuels to clean.

#hydrogenstrategy #systemintegration #EUGreenDeal
Scaling up the use and production of clean #hydrogen is key for a strong, competitive, and carbon-free economy. The hydrogen strategy and the investment plan that comes with it will not only bring jobs in the hydrogen sector, but also propel industry into the 21st century.
We want to maintain steel production in Europe. That is in our industrial strategy. And with hydrogen we can make it happen: we can produce green steel in Europe 🌱

This big breakthrough from @RishiSunak is to be welcomed unequivocally as a stimulus measure - & for #NetZero too, provided it becomes a piece of a larger puzzle, a #GatewayDrug to next-level #decarbonisation and credible #COP26 presidency - THREAD (1/11)

bbc.co.uk/news/business-…
🧩 rented homes: my reading is that private landlords will be able to access the voucher scheme, but lets see. Social housing has a £50m pilot - I think this will kick off the £3.8bn Social Housing Decarbonisation Fund, but let's see. (2/11)
🧩 jobs: safe to say we want the 120,000 jobs from this to be around for more than a year. This is a big number and more will be needed - let's think how these can be folded into a #justtransition, which includes ending #fuelpoverty. (3/11)

So, @RWE is trying to gain public support for its #LNG terminals in Germany by leading us to believe there is a #hydrogen future. Let us unpack this a little (THREAD):

germanlng.com/wp-content/upl…

@peteraltmaier @SvenjaSchulze68 @GheorghiuAndy @ConstZerger
1/ The #LNG infrastructure planned is not ready for H2. @TUHamburg explains that you need a temperature of <-250C for liquified H2, vs <-100C for liquified gas, we are yet to see plans that show the design can cope. Well explained here in @TspBackgroundEK background.tagesspiegel.de/energie-klima/…
2/ Shipping H2 is something that people working in the #maritime industry are wary of. It is highly flammable and the safety risks associated would drive up insurance premia. Given low energy density, you'd need many more loads for same value --> expensive.

Merkel: we live in times of societal change, especially due to climate change and digitalisation, hence we need a future oriented package. That’s the right framing for the 🇩🇪 stimulus package, let’s see what it actually does...
€130bn package - that’s more than most expected. Strong sign but will make European cohesion & solidarity even more important to avoid imbalances.
Cap for renewable energy surcharge as asked for by @AgoraEW and others and support for municipalities. Let’s see whether there are also investments for low carbon technologies in the mix?

Thread (1/9) Proud of our new report! So many messages distilled for you, by our team @EU_ScienceHub and from a polyphony of #EnergyScenarios. Let the deeper understanding of it mature now. Enjoy its taste !
ec.europa.eu/jrc/en/publica… #EUGreenDeal
(2/9) Scenarios achieving 50-56% CO2 reduction by 2030 see total #coal use reduce by 70%, #oil by 25-50% and #naturalgas by up to 25%. The use of total #biomass ranges from limited growth to an increase of up to 60%. All compared to 2017.
(3/9) The growth of #wind power generation varies between a factor of 1.5 and 3.5 and the growth of #solar power between 1.5 and 4.5. Between 2017 and 2030.
#Hydrogen and #CCUS emerges in some but not all scenarios.

My trusty energy engineer source is back with some interesting comments on today's disturbing news of a federal bailout of the oil & gas industry. He has some ideas on what Canada should be doing instead: 1/x
#bcpoli #SiteC #LNGCanada #CoastalGasLink #Wetsuweten #ableg #cdnpoli
First, here is the news of Canada's federal bailout of the oil & gas sector in the midst of the #covid19 pandemic, instead of letting the industry sunset & retraining workers & incentivizing alternatives: 2/x theglobeandmail.com/politics/artic… #cdnpoli
Engineer: 'the Canadian oil & gas sector is on its knees. It cannot compete with big global producers, esp with its inferior oil product. Maybe time to use the bailout money to switch to hydrogen & keep people employed in a growing industry, not a dying one we can't compete in..'

Horrific #Bushfires 🔥 are burning in every Australian state. No wonder people are angry + despairing about lack of action on the #ClimateCrisis

But w/out glossing over tragedy, here's a list of things happening right now in Australia that inspire me.
Thread:
Australia is installing #RenewableEnergy at an amazing rate DESPITE federal govt resistance. We're on track to have ~ 30% renewable energy by 2021. Imagine what could happen with fed govt support!
theconversation.com/australia-is-t…
The ACT is now on 100% renewable energy as of Jan 1st 🌞🌬️

Minister Angus Taylor addressed the UN Climate Conference #COP25 today

While Australia is on fire, impacts supercharged by climate change, the Australian government is lobbying for it (and others) to do less climate action

Worth letting that sink in

Mega thread #auspol
Speech - "The Paris Agreement sent a powerful signal to the world that countries are serious about climate action...

Unfortunately this doesn't extend to Aus, with
rising
- emissions
- fossil fuel exports
- climate impacts
- reliance on loopholes

climatechangenews.com/2019/12/06/one…
“Australia is committed to the Paris Agreement. We are already on track to meet and beat the target we have set for 2030…

Actually emissions continue to trend upwards, noting a sight dip due to loss of agriculture from climate impacts...

*Thread* Our technical report shows how a Net Zero target can be delivered across the economy through a range of costed scenarios. (1/15) #NetZeroUK theccc.org.uk/publication/ne…
Power sector emissions can be reduced to almost zero through the deployment of #renewables and firm low-carbon power - such as nuclear and CCS - whilst providing twice the amount of electricity as today. Gas will continue to play a role, but will need to be decarbonised. (2/15)
The UK has vast renewable resources. Deploying renewables is the lowest cost way to reduce power sector emissions. This means that, in aggregate, a low-carbon power system costs around the same as a high carbon alternative. (3/15)

Over 10 years ago, @ChemistryWorld started a project with the @NakedScientists (especially @Meera_Senthi) to tell the story of each chemical #element: The Chemistry in its Element #podcast. Let's look back for #IYPT2019. Here's @brianclegg with #hydrogen:

chemistryworld.com/podcasts/hydro…
@ChemistryWorld @NakedScientists @Meera_Senthi @brianclegg The podcasts weren't published in atomic number order – we jumped around the #periodictable a bit – but here's @peterwothers getting grumpy about party balloons and the loss of the precious elemental resource: #Helium
chemistryworld.com/podcasts/heliu…

#IYPT2019
#Lithium lubricates bearings & boosts batteries, but is also an important drug for depression and bipolar disorder. Nirvana sang about it in 1990 and, hot on their heels, Matt Wilkinson wrote a #podcast for @ChemistryWorld in 2009: chemistryworld.com/podcasts/lithi… #IYPT2019 #Mendeleev

We have just published our Review of Energy Policy: 2018!
Check out the thread below for a summary of all our recommendations.
Read the review in full here: bit.ly/2BsqDqf
On #Transport: The target for phasing our conventionally fuelled vehicles is inadequate. The @transportgovuk ‘Road to Zero’ (‘ICE ban 2040’) may neither hit the target nor make the early gains needed for a 1.5°C trajectory. @_chris_brand_ @jillian_anable
On #electricity: policy should build on Electricity Market Reform that has worked well & adapt in the light of technology/cost changes. Change in ‘black start’ incentives & other ancillary services are needed to ensure the system remains resilient @energyukcomms @ngcontrolroom

#Hydrogen #FCEV vehicles are very unlikely to become any kind of transport solution because they just don't make environmental or economic sense when compared to battery electric vehicles. #BEV
Hydrogen itself is just another fossil fuel as almost all of it is made from natural gas with carbon emissions as a significant byproduct. So the basic premise of the #FCEV is destroyed right there because it's just another fossil fuel car and not #Green at all.
The only other significant means of production is electrolysis which accounts for only 4% of all commercially available hydrogen fuel. It's used for only this tiny amount of production because it's massively inefficient, throwing away up to 75% of the electrical energy input.
