Carbon Commentary newsletter from Chris Goodall. [Note - he's busy for a few weeks so no newsletter for a while.]

No. 7 is interesting, suggesting that green funding is to exceed FF funding in 2021 for the first time.

Industry news

Things I noticed and thought were interesting

Week ending 12th December 2021
 
1, Methanol as shipping fuel. Maersk said it was not certain that it would have green methanol available for the first delivery of its dual-fuel container ships in 2024. (Green methanol requires the carbon in the molecule not to be from fossil fuels). However it expressed confidence that it would have plenty of supply the following year for the eight new vessels. Some outlines of the design for the new ships were released, showing that the extra space needed for the methanol storage tanks will be provided by shifting the location of crew accommodation. This week a Netherlands consortium received government funding to trial large-scale methanol on ships. One ship owner said for a large scale transition to low carbon shipping, ‘the most viable option is methanol’. 
 
2, Wind to H2. Last month Siemens Gamesa delivered hydrogen directly from an onshore wind turbine for fuel cell vehicles in Denmark. This was said to be the first example of H2 production from an ‘islanded’ wind turbine without an active connection to the electricity grid. Siemens’ longer term aim is produce large quantities offshore and it announced a partnership this week with Strohm, the leading manufacturer of flexible plastic pipes suitable for use transporting hydrogen from the turbine to onshore distribution grids.
 
3, Heat for industrial processes. Hydrogen may be able to replace natural gas in many industrial processes that require very high temperatures. Hydrogen combusts at around 2,000 degrees in air, about the same as natural gas. Several industries are beginning the early stages of experimentation to trial the use of H2 for high temperature industrial heat. Australian mining company Infinity Minerals intends to work with ThyssenKrupp on experiments to manufacture lithium. It is using a technology that should enable 100% substitution by hydrogen. Although lithium manufacture for batteries is not a major use of natural gas at the moment, increased needs for electricity storage are likely to cause sharp rises in the amount of lithium processed. My estimate of the lithium needed for batteries suggest that a stock of 4.5 million tonnes will be needed for private cars alone by 2050 (assuming 100% recycling) but 2020 lithium global production was only around 80,000 tonnes. 
 
4, Solid state batteries. The arrival of inexpensive solid state batteries will be an important moment for the automobile industry. Eventually, the energy density (kWh/kg and kWh/l) may be up to twice as good as today's lithium ion products. (Two reports this week have been critical of electric cars because the increased weight may cause more damage to roads). GM indicated it will build a new factory with the Korean chemicals firm Posco to make cathode materials for a range of standardised batteries. Cathodes currently comprise about 40% of the cost of a battery cell. VW also signed a deal with partners to enable the expansion of its battery capacity to cover the requirements for the batteries of 2.2m cars by 2030. VW makes about 9.5m cars a year at the moment and expects 60% electrification by this date. In both cases, the joint ventures appear to be aimed at speeding up the delivery of a standardised solid state lithium-based battery usable across most of the range of the two manufacturers. The drive of the main car makers into the battery manufacturing business may undermine the specialists such as CATL.
 
5, Small scale hydrogen production. Most weeks now see announcements of hydrogen projects of 1 GW or more. Wood Mackenzie said that its database records at least 180 GW of plans around the world, up seven fold in the last year. What is happening at the other end of the scale? Does it make sense for individual buildings to make hydrogen from surplus solar electricity to then use in months of weak sun? Many have doubted this. But as retail electricity prices rise steeply, particularly across Europe, the financial logic may change. Enapter, the innovative Italian/German electrolyser producer has consistently claimed its small units can be used make a home self-sufficient in energy by storing hydrogen. Home Power Solutions, another German company, announced that its existing small hydrogen solution could now be seamlessly linked to up to nine other units, storing up to 15 MWh of electricity in the form of hydrogen for larger buildings. Small electrolysers are still remarkably expensive, probably at least five times the price of the huge units now being planned around the world. And conventional electrolysers are expected to fall in cost by another 35-50% by 2025. Nevertheless high home electricity prices will provide a boost to the appeal of micro-electrolysers combined with hydrogen storage. (Thanks to Nick Hanna)
 
6, Lower carbon cement. Global producer Cemex linked with Carbon8, a UK innovator, to investigate the use of a new technology to store captured CO2 from the cement production process. Carbon8 takes carbon dioxide directly from process gases and combines it with the dust from the production of cement to manufacture a lightweight aggregate which can then be used in construction, permanently storing the carbon. This is the second deal with a cement industry participant this year after the pilot installation of one of the company’s modular containers at a French cement works last year.
 
7, Oil and gas investment. According to the International Energy Forum, an oil industry body, lending to fossil fuel companies will be less than the value of the debt raised by green projects in 2021. This will be the first time that green lending ($466bn) has exceeded that to conventional energy ($460bn). Only three years ago, lending to fossil fuels exceeded $750bn. The capital shortage for the oil companies will result in a sharp decline in projected output. ‘Remarkably’ the Forum says, ‘there are currently no new greenfield megaprojects planned in the next five years’ in the global oil industry. As might be expected, the industry body says that the lack of new money flowing into oil will cause acute supply shortages as oilfields run down. It ‘calls for oil and gas to account for 55% of the primary energy demand in 2030, slightly above 2020 levels’ and for investment in new fields to rise by over 50% from current levels. Parts of the fossil fuel industry still don’t seem to recognise the strength of the argument that decarbonisation is an urgent necessity.

8, Timber buildings. The World Economic Forum (WEF) suggested that cross laminated or ‘mass’ timber ‘is likely to take off at scale over the next decade’. The key advantages over concrete and steel include, of course, a potentially negative carbon footprint but also a much simpler supply chain, if construction takes place close to sources of timber.  Although still relatively uncommon, mass timber is now used in a wide variety of buildings, large and small. One UK architect commented that its use had cut construction time and costs by 15% on a small block of apartments. In Los Angeles, a mixed use building nearly 25 metres high and offering 11,000 square metres in floor space will be completed next year. The journalist commenting on this elegant building noted that the US construction industry produces 600 million tonnes of waste material a year, more than twice the weight of all municipal wastes. Widespread use of mass timber would reduce the amount of unrecyclable material.
 
Work demands mean that I will not be able to complete this newsletter over the next few weeks. Many apologies and thank you very much for all the comments over the last few months.

The EIA have produced and released a 2021 report on renewables. I suspect we are all now used to the EIA massively underestimating the rollout of RE, as they tend to draw a straight(ish) line into the future based on the last years worth of deployments, rather than expecting significant growth.

So with the EIA's tendency to underestimate in mind, check out this paragraph from the report (it's in the executive summary) that I've boldened:

Renewables 2021

The growth of renewable capacity is forecast to accelerate in the next five years, accounting for almost 95% of the increase in global power capacity through 2026. We have revised up our forecast from a year earlier, as stronger policy support and ambitious climate targets announced for COP26 outweigh the current record commodity prices that have increased the costs of building new wind and solar PV installations. Globally, renewable electricity capacity is forecast to increase by over 60% between 2020 and 2026, reaching more than 4 800 GW. This is equivalent to the current global power capacity of fossil fuels and nuclear combined. Overall, China remains the leader over the next five years, accounting for 43% of global renewable capacity growth, followed by Europe, the United States and India. These four markets alone account for 80% of renewable capacity expansion worldwide.

Now, of course that's capacity, not generation, but what a potential short term milestone, and of course as RE capacity grows, the capacity factor / load factor of FF generation falls, and so does its profitability, especially when RE generates during peak demand periods and thus reduces prices (or reduces the increase in prices).

This link was posted in the main "Energy" section but I thought I'd pinch it and post it here too:

https://theenergyst.com/contracts-for-difference-auctions-open-ar4-bigger-than-all-the-rest/

Power developers in clean tidal, solar, and wind technologies jumped at the starting gun today, competing for a slice of the government’s record £285 million support in the nation’s biggest ever Contracts for Difference auctions.

With up to 12 GW of renewables capacity to be awarded, the long-awaited Allocation Round 4 is bigger than the combination of its three predecessors.  Would-be generators have until January 14 to submit bids. D-BEIS will announce the outcomes next spring.

Strike prices here.  I can't see what limits the max auction size to 12GW if bids come in at a level that does not exhaust the subsidy pot?

Yeah true, and the max figures for PV, onshore and offshore wind suggest they expect competitive bids.
If the last two CfD's massive reductions in offshore wind prices are anything to go by, then this round should be exciting if costs across those 3 areas can come in at good rates.
Jumping ahead, I also hope that the Govt shifts to an annual CfD auction, rather than every two years, but one thing at a time.

OK hands up if you were completely unaware of this ...... just me then? I don't know the energy figure, I've read several news articles now, but they seem to all contain roughly the same press info, but if I find an energy figure I'll post it.

So one great big battery for Teeside is being planned, and by big, 1/3rd of a GW big.

Sembcorp Energy UK reveals 70-job plans for “Europe’s largest battery energy storage system”

A power firm has revealed plans to create “Europe’s largest battery energy storage system”.

Sembcorp Energy UK aims to build a 360MW hub at its base on the Wilton International complex, near Redcar, which it says will help the UK meet net-zero targets.

Bosses say the move will create 70 jobs, “help ensure the resilience of the electricity network, and further enable the increasing growth of renewables”.

Sembcorp already operates 70MW of batteries, with a further 50MW due to become operational in early 2022.

Why does Australia burn sooooo much coal?

Spies said:

Why does Australia burn sooooo much coal? 

Probably because it's mostly open-cast and so much cheaper than anyone else in the world that they export a lot.  Cost of sending it to a nearby power station is pretty small too.

No doubt one day they'll realise that their abundant sunshine gives even cheaper generation but there are probably a lot of voters in the coal industry.

Spies said:

Why does Australia burn sooooo much coal? 

As Eric says the coal is cheap, also Australia's economy benefits massively from mining and exports, and one of their main exports was coal, though this is dropping as China, India (and other parts of Asia) have slowed down their coal generation expansion as they've rolled out large amounts of RE.

Australia has therefore been a significant climate change denier, or to be fairer, their central government has, after all if you want to export vast amounts of coal, you'd hardly want to believe in AGW, as per the old quote - "It is difficult to get a man to understand something when his salary depends upon his not understanding it."

Now for the good news, whilst the central Gov is still slow to come round to tackling AGW, and displayed this recently at  COP26 in Glasgow, the state governments and people seem to be greatly more accepting of RE, especially PV.

Domestic PV in Aus is staggering, it's on about 30% of properties. It's almost perfect for Aus, since they have a larger number of single storey properties, which allows for larger systems (larger roofs), easier to install, about 60-80% more annual generation than the UK, more predictable sunshine, and a much tighter spread of generation from best month v's worst across the year, perhaps 2:1 (or better) whereas the UK is around 4:1 for a steepish south facing roof, and closer to 8:1 for shallow E/W roofs like mine.

Oh, and to rub salt into the wound, Aus has some of the cheapest (A$/Wp) solar install prices in the World. So as Eric points out they have an incredible RE resource, with some of the lowest generation prices in the World, and to add to that, they also have cheap(ish) land with most of the population living near the coast, where winds help to make wind power pretty damn good too.

Watch out for some incredible figures from the states as the years go on. South Australia has changed their energy mix massively already.

[I appreciate you didn't ask for all this waffle, but Aus is so interesting as they are 'one of the worst' in so many ways, yet their potential and direction of travel is heartening. M.]

7 renewable energy lessons from South Australia

The South Australia state government set a 2020 target of getting 26% of the state’s energy from renewables. It smashed that goal, with renewables delivering 60% of its energy needs. In October of that year, 100% of the state’s energy came from solar sources – just for one hour, but it marks an impressive turnaround for a region that was 100% reliant on fossil fuel as recently as 2006.
