Energy Minister Angus Taylor Launches $50 million Fund For Carbon Capture Projects

The title of this post, is the same as that of this article on ABC News.

This is the introductory paragraph.

The federal government has launched a $50 million fund to support the growth of carbon capture projects, which will include projects that reuse carbon dioxide emissions to make new products.

The launch of the Carbon Capture, Use and Storage fund was in Newcastle at the pilot site for Mineral Carbonisation International (MCI).

The company is using carbon dioxide (CO2) captured from a nearby ammonia plant to make building products like plasterboard and cement.

This sounds like a good idea to me!

They have a web site, which contains this YouTube video.

This could be a novel solution to decarbonisation.

World’s Biggest Battery Storage Project Announced By Australian Renewables Fund

The title of this post, is the same as that of this article on Energy Storage News.

This is the introductory paragraph.

CEP. Energy, a specialist renewable energy fund company in Australia, has just announced the largest proposed grid-scale battery project in the world so far, with up to 1,200MW rated output.

If you read the whole article, you get the impression, that the Australians are going big on energy storage.

But then Australia must be one of the best countries for solar energy in the world.

This paragraph contains an interesting concept.

Construction is anticipated to begin in early 2022 for completion in 2023, so it’s possible even bigger schemes will be announced or even built by then, but for now the project is setting the pace for scale. Another Australian project, proposed by integrated energy company Origin Energy would site 700MW / 2,800MWh of batteries at a retiring coal power station, also in New South Wales and French developer Neoen has filed a plan, to build a 500MW / 1,000MWh battery storage project in the state. New South Wales’s government has implemented an ambitious roadmap to deploying vast shares of renewable energy on its networks, including a handful of multi-gigawatt Renewable Energy Zones.

Note that Origin Energy are replacing a coal-fired power station with a 700 MW/2,800 MWh battery.

We shall see a lot of fossil-fuel-fired power stations replaced by batteries.

Renewable Hydrogen Will Replace Natural Gas In Millions Of Australian Households

The title of this post, is the same as that of this article on Hydrogen Fuel News.

This is the introductory paragraph.

Under a new Australian government-backed initiative, millions of households across the country will be supplied with renewable hydrogen in the place of natural gas.

The project will start in a small way by adding 10 % of hydrogen to the natural gas networks by the end of 2022.

Eventually, hydrogen will completely replace natural gas.

According to one of the comments to the article, ITM Power will supply the electrolysers.

That could be a nice little order.

magniX, Sydney Seaplanes And Dante Aeronautical Partner For World’s First All Electric Cessna Caravan STC Program

The title of this post, is the same as that as this article on Cision.

This sub-title defines their objective.

Global leader in electric propulsion technology to work with leading charter and integrator companies in Australia and the South Pacific to provide electric aircraft.

Note.

  1. An STC is a Supplemental Type Certificate, which is added to the aircraft’s type certificate, to allow it to be flown, after a major modification, such as a different power plant or a structural modification, such as a cargo door or aerodynamic modification.
  2. In the case of the Cessna Caravan, the gas turbine engine is being replaced by an electric motor and batteries.
  3. Over 2, 600 Cessna Caravans have been built.

This picture shows the Cessna Caravan in which I flew in Kenya.

I look forward to flying in an electric Caravan!

Queensland Establishes Minister For Hydrogen

The title of this post, is the same as that of this article on H2 View.

This sounds like a good idea and every civilised country should have one!

It’s also good to see Queensland up in front.

They must have got their act together, since I the day I left Alice Springs in Northern Territories for Mount Isa in Queensland, when I was flying round Australia in a Piper Arrow with C.

As Australian states all seemed to be in different time zones, I said to an Air Traffic Controller, “By the way, what time is it in Queensland?”

He quickly replied. “They’re thirty minutes ahead! And twenty-five years behind!”

H2U Eyre Peninsula Gateway Hydrogen Project Begins Largest Green Ammonia Plant

The title of this post, is the same as that of this article on Hydrogen Fuel News.

  • South Australia will be creating the largest green ammonia plant in the world.
  • It will make 40,000 tonnes of green ammonia every year.
  • The plant will be powered totally by renewable energy.
  • At its heart will be a 75 MW hydrogen electrolyser.

This paragraph sums up the main objective of the plant.

According to Dr. Attilio Pigneri, H2U CEO, the project will play an important role in the ongoing development of the emerging green hydrogen and green ammonia markets.

It appears a lot of the green ammonia will be exported to Japan.

What Is Green Ammonia?

It is just ammonia produced by renewable energy. This is the first paragraph of the Wikipedia entry for ammonia.

Ammonia is a compound of nitrogen and hydrogen with the formula NH3. A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a characteristic pungent smell. It is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceutical products and is used in many commercial cleaning products. It is mainly collected by downward displacement of both air and water.

It is a very useful chemical compound and it is now being developed as a zero-carbon fuel, as I wrote in The Foul-Smelling Fuel That Could Power Big Ships.

It can also be used as a refrigerant.

One of the most amazing pieces of engineering, I ever saw was a very old barn, where a farmer stored vast tonnages of apples. It was kept cool, by a refrigeration plant certainly built before the Second World War or possibly even the First, which used ammonia as the refrigerant.

Now that’s what I call engineering!

Solar To Hydrogen Efficiency Record Broken By Australian National University Researchers

The title of this post, is the same as that of this article on Hydrogen Fuel News.

The traditional route to produce green hydrogen from solar panels, is to create electricity and then use electrolysis to create the hydrogen.

This process goes direct and an improvement in efficiency of 17.6 %.

MagniX Electric Aircraft Engines Take To The Skies

The title of this post, is the same as that of this article on pv magazine Australia.

This is the introductory paragraph.

No emissions, low-cost regional flights with just eight other sanitised folk and a disinfected pilot… Yes, Covid-19 is warping our view of the future, but the successful electrically powered maiden flight last week of a Cessna Caravan aircraft, offers the potential for new models of travel supporting wider distribution of commerce in Australia.

The article goes on to discuss Roei Ganzarski’s vision of what zero-emission electrically-powered aviation could do.

Economics

This is a paragraph from the article.

Its successful half-hour, 160km test flight used less than US$6 worth of electricity, compared to a Cessna Caravan powered by conventional combustion engine which would have sucked up some US$300-400 worth of fuel. And Ganzarski points out that, as in electric vehicles, the motor requires very little maintenance compared to its gas-guzzling cousins.

That is impressive.

The Market

This is a sentence from the article.

MagniX says 45% of all airline flights cover less than 800 km, while 5% of flights are sub-160 km, and it’s likely that commercial electric flights powered by magniX motors will first be offered in the UK, US or Europe.

I didn’t believe that the proportion of short flights was so high.

I could see all flights below 160 km (100 miles) will be flown by electric aircraft and a large proportion of those below (800 km (500 miles) going in the same direction.

The Vision

This is a paragraph from the article.

You could have phenomenal factories or businesses in these places that can’t currently sell their goods or can’t receive goods because the 4.5 to 6-hour truck drive that happens maybe once a week is just operatively prohibitive. If you could have an aircraft do that in 20, 40, 60 minutes and do it with zero emissions at a really low cost, and suddenly you’re really connecting these communities…

As it was given in quotes, I would assume it was spoken by Roei Ganzarski.

What would that do for high-quality agricultural products and seafood produced on remote islands.

This statement is in the Wikipedia entry for Loganair.

Loganair is planning to introduce electric aircraft to the Orkney Islands by 2021 due to the short distance between the islands that would make such flights possible.

They seem to be following a parallel path, with their involvement in Project Fresson. But as that development of a Britten-Norman Islander, is not planned to fly until 2022, could Loganair be a possible launch customer for an electric Cessna Caravan?

  • Loganair have the ideal short routes.
  • The electric Caravan won’t be the most difficult aircraft to certify for flying with a Supplemental Type Certificate, as several other Caravan variants with a change of powerplant, are flown this way.
  • The environmental profile fits some of Loganair’s routes in Scotland.
  • According to Roei Ganzarski, the economics would be ideal for Loganair’s routes.
  • Roei Ganzarski gave a long sales promotion-style interview on the BBC. Who was he targetting?

But the biggest factor is that Roei Ganzarski appears to be a showman in the mould of those great Victorian engineer/entrepreneurs, who defined and built much of the world we admire. What better stage is there to showcase his electric aircraft, but the remote airports served by Loganair?

The Specification

The Wikipedia entry for the Cessna Caravan now has s section for the electric Caravan, where this is said.

The eCaravan is an electric aircraft modification of the 208B built by AeroTEC and magniX powered by a 750 hp (560 kW) motor and a 1 t (2,200 lb), 750V lithium-ion battery. Its 30 min first flight happened from Grant County International Airport in Moses Lake, Washington, on May 28, 2020, consuming $6 worth of electricity, needing 30-40 min of charging. The Magni500-powered variant can fly 100 mi (160 km) with 4-5 passengers while keeping reserve power, and aims for a certification by the end of 2021, hoping to operate 100-mile flights with a full load of nine passengers with better batteries.

The pv magazine Australia article says the flight was for 160 km (100 miles), so that would cover a lot of short routes.

Suppose with reserves, that the plane should have a one hour endurance. my experience of piloting aircraft leads me to estimate that the average power setting would be less than fifty percent of full power for a real flight, as cruise and descent, need a lot less power than climb.

This would mean, that the aircraft needs to take-off with around 280 kWh of fuel, which would be enough to power the motor at half-power for an hour.

In Sparking A Revolution, I comment on an article of the same name in Issue 898 of Rail Magazine, which talks about Hitachi’s plans for battery-electric trains.

This is an insert in the Rail Magazine article, which will apply to all applications with traction batteries. Including aviation!

This is said.

The costs of batteries are expected to halve in the next five years, before dropping further again by 2030.

Hitachi cites research by Bloomberg New Energy Finance (BNEF) which expects costs to fall from £135/kWh at the pack level today to £67/kWh in 2025 and £47/kWh in 2030.

United Kingdom Research and Innovation (UKRI)  is also predicting that battery energy density will double in the next 15 years, from 700 Wh/l to 1,400 Wh/l in 2035, while power density (fast charging) is likely to increase four times in the same period from 3 kW/kg now to 12 kW/kg in 2035.

This page on the Clean Energy institute at the University of Washington is entitled Lithium-Ion Battery.

This is a sentence from the page.

Compared to the other high-quality rechargeable battery technologies (nickel-cadmium or nickel-metal-hydride), Li-ion batteries have a number of advantages. They have one of the highest energy densities of any battery technology today (100-265 Wh/kg or 250-670 Wh/L).

The highest figure of 670 Wh/l would appear to fit the Hitachi extract, where 700 Wh/l is quoted.

If I use the Wh/kg figure, it would appear that a one tonne battery could hold between 100 kWh and 265 kWh.

I suspect, that the higher figure would be enough to perform the 160 km. test flight, which I estimated could need 280 kWh.

But battery development in the next few years will be on the side of Roei Ganzarski’s vision.

Conclusion

Electric aircraft are not a politically correct mad idea, but a serious proposition to make the world a better place.

The article is a must-read!

H2OzBus Project: Deploying Hydrogen Fuel Cell Bus Fleets For Public Transport Across Australia

The title of the this post, is the same as that of this Press Release from ITM Power.

This is the introductory paragraph.

ITM Power, the energy storage and clean fuel company, is pleased to announce the formation of the H2OzBus Project (“the Project”) and the signing of a memorandum of understanding with strategic partners (“the Consortium”).  The Consortium comprises Transit Systems, part of the SeaLink Travel Group, Ballard Power Systems, BOC Limited, Palisade Investment Partners and ITM Power.  The Consortium partners have signed a memorandum of understanding as a further step in evaluating and demonstrating the concept of hydrogen fuel cell electric buses for use in public bus transport in Australia.

Some further points from the Press Release.

  • Initially, a hundred buses will be deployed.
  • The buses appear to be being built in Australia.
  • Ten locations are being considered for the buses.

It looks to be a very sensible project.

Australia’s New Community Solar, Solar-Storage, ‘Solar Hydro’ And Solar Hydrogen Projects

The title of this post is the same as that of this article on Energy Storage News.

This is the introductory paragraph.

In the past couple of weeks, national and state government organisations in Australia have announced various stages of consideration for solar projects with a range of advanced and innovative storage solutions attached.

The article then goes on to describe some projects.

RayGen’s PV Ultra System

This paragraph describes the PV Ultra system.

The fully dispatchable power plant would use RayGen’s own technology PV Ultra, which is a combination of photovoltaic (PV) solar generation with the more expensive and engineering-intensive concentrated solar technology using angled mirror towers (heliostats). The PV Ultra system would generate both electricity and heat.

It’s obviously using what Australia has a lot of; sun to advantage.

RayGen’s Innovative Thermal Storage

This paragraph outlines the principle of RayGen’s thermal method of storage.

This generation technology would in turn be co-located and connected to a ‘Thermal Hydro’ energy storage facility, with 17 hours of storage, which again is based on a technology RayGen is developing. Unlike pumped hydro energy storage which uses two reservoirs at different heights, relying on gravity to drive turbines, the Thermal Hydro plant would use a hot reservoir and a cold reservoir, linked together.

The principle of operation is described in this second paragraph.

The PV Ultra solution will therefore cool one reservoir using photovoltaic power and grid power when needed, while also heating the other reservoir using the heliostats. The difference in temperature would then generate electricity, via an Organic Rankine Cycle engine, a device which uses thermodynamic cycles to convert steam into mechanical energy and is widely used for biomass, waste incinerators and other existing generation types.

The article states that an Organic Rankine cycle engine has an efficiency of about seventy percent. I have linked to Wikipedia, which gives a good explanation of the Organic Rankine cycle, which is typically used in waste heat recovery and biomass power plants.

RayGen’s Flagship Project

RayGen’s flagship project will be rated at 4 MW, with a storage capacity of 50 MWh. It will be used to provide power in the West Murray region.

 

New South Wales Community Projects

The article then describes a group of community projects that are being set up in New South Wales.

This is the introductory paragraph

Elsewhere in Australia, the government of New South Wales approved grants earlier this month to assist the development of seven solar projects, all but one of which will include energy storage. Notably, five out of the seven will also be community distributed energy projects, including one standalone shared battery energy storage site.

Some points from the article include.

  • The total solar power is rated at 17.2 MW.
  • The energy storage is rated at 39.2 MWh
  • One site is co-located with hydrogen electrolysis and storage,

New South Wales has certainly launched an ambitious plan.

Conclusion

I like RayGen’s system and the New South Wales initiative.

I also think, that both projects could find applications in some of the hotter places in the world.

Could solar power systems like these solve power supply problems in Africa, India and other sun-rich places>
