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.

Offtake risk has become a blanket term that scares investors away from #power sector projects in India. We break it down to understand why that is? 1/n
Offtake risk is the risk posed by the off-taker (also called credit risk, counterparty risk or risk on receivables). In India, the counterparty is almost always a discom or a central government offtaker (SECI/NTPC) buying on behalf of the discoms. 2/n
The power purchase agreement (PPA) is the contract between the power generator and the purchaser (discom/SECI/etc) For RE the PPA mandates that all power generated must be purchased/paid for as per the must run clause. Exceptions are allowed only if there is technical trouble 3/n

I see discussion has started about possible ‘green’ recovery plans once we are passed the worst of #COVID19. What can we learn from @CambridgeEcon analysis of green recovery plans after the 2008 financial crisis? (1/8)
ec.europa.eu/environment/en…
First, the recovery plans weren’t very green. Even ones that were it was often for non-green reasons (e.g. building green stuff to help the cement sector). There is definitely scope for more ambition. (2/8)
The most ‘green’ common policies were 1) #energyefficiency, 2) vehicle scrappage schemes (not green), 3) investment in #renewables and 4) support for low-carbon innovation.

Looking back, funny to think how much attention car companies got. (3/8)

Ok folks its time to talk about overbuilding renewable energy as the quickest and cheapest way to a low-carbon future for Australia.

THREAD
Firstly if you're thinking about both the economic recovery from the #Covid_19australia crisis and how to respond to the #climatecrisis, I highly recommend the excellent work of @Anna_Skarbek's team @ClimateWorksAus in their latest report. See @adamlmorton's article for summary
The analysis by @ClimateWorksAus "suggests over-building renewable energy to 200% capacity – double what the country needs – could be more cost-effective than building to 100%, and would spark new clean export opportunities."

Great to see draft #HeatNetworksBill laid in @ScotParl by @ScotGovEnergy today 👏

Heat networks can grow our use of #renewable heat & cut emissions on the path to #NetZero

Here's a rundown of the key policies in the Bill (THREAD) @ScotRenew 🔥

parliament.scot/parliamentaryb…
The Bill will introduce a Scottish Heat Networks License, to technical standards & customer service (within devolved powers). Important to ensure we build high-quality #HeatNetworks in future (2/9)
A ‘Network Wayleave Right’: license will confer powers to lay pipes to the edge of a building, inspired by the Danish obligation to connect. Won’t solve the anchor load problem but will address issues around if/where pipes can go. Who pays is key question #climatechange (3/9)

Tonight on @abc730 @leighsales asked some serious questions of Scott Morrison on #climatechange. However, there are some additional questions it would have been great if she'd asked...

THREAD
#auspol #ClimateCrisis
@abc730 @leighsales 1. You talk about not wanting anyone to lose their job - what about the thousands of people who are losing their job in the #renewables industry right now due to the lack of policy certainty and the lack of a plan to decarbonise our electricity sector? Do their jobs not count?
@abc730 @leighsales 2. Scientists say that your current plan to cut emissions by 2030 will lead to warming of more than 3 degrees - much higher than the Paris targets - what is the cost of more than 3degrees of warming to the Australian economy?

Range anxiety is a real concern for changing our mindset around #ElectricVehicles.

Just how close to the left of the needle can we go?

Tomorrow I’ve got a few offsite #CSIRO meetings between #Newcastle & #Sydney, so why not come on:
“A day in the life of an #EV

Starting, NOW!
Off on the first leg of the #EV trip, leaving work for the day: I have an 8am meeting so will get a head start.

Leaving the charging point behind & starting with a ~full charge + range of 429 km.

Bring on tomorrow’s #RangeAnxiety experiment!
@TheDriven_io @AEVA_National #CSIRO
First leg of #RangeAnxiety experiment 🧪went as expected:

16 km trip from Office to Home, 15 km reduction in range.

Now to take the dog 🐕 for a bush walk & await the next experimental leg.

HAPPENING NOW: #RFFlive’s “Making Sense of @FERC’s #MOPR Order.” Watch the livestream on our event webpage: buff.ly/2NjS9g3

#EnergyTwitter #FutureOfPower
@FERC 2/ RFF’s Kathryne Cleary is giving a brief primer on @FERC’s #MOPR order. Some context: @pjminterconnect’s capacity market, which we’re here to discuss today, is intended to promote investment and ensure adequate supply is available to meet demand.
@FERC @pjminterconnect 3/ Cleary: PJM has had an existing #MOPR in place since 2006, which was originally intended for new #NatGas plants to prevent them from bidding into the market at low prices. This MOPR order expands upon that to include state-subsidized resources.

There's no point in investing 50% of your money in saving the climate and the other 50% in destroying it.

So says Dr. Werner Hoyer, CEO of the @EIB at an exchange of views with the @EP_Environment.
@EIB @EP_Environment @GraceOSllvn Excellent questions by @michabl on the revision of next sectoral lending policies of the @EIB and the potentially big loopholes around 'low carbon gases', CCS and the 4th PCI list.
@EIB @EP_Environment @GraceOSllvn @michabl Now an Italian MEP for the ID Group is saying that climate financing by the @EIB is creating a bubble and is defending the interests of big interests, rather than protecting citizens.

1/15: [THREAD] Unpacking the Headlines:
20 GW of #NuclearPower planned in India by 2030

2 ways to analyze:
1)Can it happen - and should it happen?
2)What’s nuclear’s role, and what’s special/different about India?

I combine both aspects in this thread
2/15: The plans tick many of the right boxes – standardized designs, fleets, etc. There is also talk of encouraging the private sector – but will they bite? Global private sector is even harder given #DifferencesOfOpinion on the nuclear liability bill.
3/15: Nuclear has many concerns for different people – fuel disposal, accidents, proliferation, etc. Latter is a non-issue as India is a proven mature actor, and it also can island safeguard civilian reactors. But what about the economics? Esp. fully loaded costs.

You're taking a job running a #renewable exports campaign? Renewable exports - what's that? Why is it important?

THREAD
Last year I came up with a #Renewable Exports typology.

I reckon there are six main types of exports.

1. Direct electricity transfer via undersea cables, like the SunCable proposal to export power to Singapore afr.com/companies/ener…
2. Clean hydrogen-based fuel, using #renewable electricity to electrolyze water. Renewable hydrogen can then be turned into other chemicals like ammonia, which can be transported more easily and safely at scale.

I was sorry not to be able to spend more than 20min at this @HighlandCouncil event yesterday. Some really good looking plans, but...

2 big housing developments, a big development of holiday accom & a hospital, none to very good energy standards.

Yesterday @scotgov announced a target of 75% reduction in GHG emissions by 2030, and the Highlands have even more ambitious targets under discussion of net zero by 2025. Fantastic, but we need focus on #EnergyEfficiency as well as #renewables.

Continuing to build inefficient houses is crazy, not just environmentally but also in terms of the health, fuel poverty and comfort of the people living in those houses. This sounds v critical, but it’s exactly what @theCCCuk said here.

Tonight on the @CNN #climateforum, Democratic candidates will talk through their plans to rapidly transition our country to clean energy. We’re guessing we’ll hear a lot about #renewables & carbon pricing. But what will they say about #nuclear energy?

#DemDebates
Will they mention that it’s the largest source of carbon free electricity in the US?

#climateforum @wolfblitzer @ErinBurnett @andersoncooper @ChrisCuomo @DonLemon
thx:@GovNuclear
Will anyone point out that, considering the scale of the challenge, we should get rid of fossil fuels before even thinking about getting rid of nuclear?

The roof was tilted and was very slippery. This was the last day of the installation and me & my men had to commission the plant by 5 pm. Each panel weighs around 20 kgs and ppl had to move them over the slippery roofs.++

The electricians had to use use drilling machines to drill holes. Due to the water, they would not work. So another person was employed to hold an umbrella over the drill, like that 125 holes were drilled. These holes were plugged++

1. @ExtinctionR Having looked at some of your policies & grievances my advice to you as a scientist is to do your own research before you jump to conclusions; resist the temptation to go down a EnergyDeadEnd path before really appreciating after years of research life's realities
2. @ExtinctionR scenario has come about through a few scientists exaggerating #ClimateChange which is a natural phenomena that has occurred since Earth had an atmosphere; one of the variables keeping us warm is yes photosynthesising #TraceGas #CO2 as well as water vapour (clouds)
3. @ExtinctionR Earth's CO2 levels vary over time & currently only 0.041% or to make it sound larger 410ppm on average; at levels below 200ppm to 150ppm #photosynthesis ceases & all life relying on plants will die off.
Many other variables are involved with #ClimateChange e.g.Sun

Huge #cleanenergy news to kick off week!

@GuzmanEnergy offering to buy three of @TriStateGT's #coal-fired power plants (and a coal mine), shut them down, replace them with #renewables.

Tri-State would be crazy to pass up this deal,

energynews.us/2019/05/28/wes…
Deal would shutter @TriStateGT's Craig power plant in NW #Colorado, also Escalante plant in #NewMexico.

@GuzmanEnergy would replace costly #coal w/more affordable #cleanenergy, saving Tri-State's rural electric co-op members higher rates, promoting local economic development.
According to @GuzmanEnergy release, proposal would also provide, "substantial financial assistance to communities negatively impacted by the early retirement of coal plants, to be driven by engagement directly with those
communities and other local partners."

*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)
