Delivery Drone Flies Medical Supplies To Britain’s Isle of Wight

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

This is the introductory paragraph.

A new drone service will reduce delivery times for urgent medical supplies to a hospital on the Isle of Wight, which lies about 8 kilometres off the south coast of England.

In some ways the most remarkable thing about this project, was that the drone was developed by Southampton University to deliver medical supplies in remote parts of Africa.

  • It is twin-engined.
  • It has a range of 100 km.
  • It can carry a 100 kg payload.
  • It can take off and land on short grass runways.

More details can be found on this page of the Southampton University web site.

This is a video of the first delivery.

Dr. Gerhard Cromme Joins Highview Power’s Board of Directors

The title of this post, is part of the title of this press release from Highview Power.

This is the introductory paragraph.

Highview Power, the global leader in long-duration energy storage solutions, is pleased to announce that Dr. Gerhard Cromme, former Chairman of the Supervisory Board at Siemens AG and ThyssenKrupp AG, will join its Board of Directors.

I think this could be a game-changing appointment.

Hydrostor Announces Australia’s First CompressedAir Energy Storage Project Secures Funding From Arena And South Australia Renewable Technology Fund

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

This is the introductory paragraph.

Hydrostor Inc., a leader in Advanced Compressed Air Energy Storage (A-CAES), is pleased to announce that its subsidiary, Hydrostor Australia Pty Ltd, has been awarded a combined total of $9 million of grant funding from the Australian Renewable Energy Agency (ARENA) and the Government of South Australia Renewable Technology Fund for Australia’s first A-CAES project, to be sited at a mine outside of Adelaide—the Angas Zinc Mine near Strathalbyn, currently in care and maintenance.

I’ll answer a few questions.

Who Are Hydrostor?

They appear to be a Canadian company based in Toronto according to their web site, which has this prominent statement.

Hydrostor is the world’s leading developer of Advanced Compressed Air Energy Storage (A-CAES)
projects, enabling the transition to a cleaner, more affordable and more flexible electricity grid.

There is also a video on the home page.

What Technology Do They Use?

This description is from the AESA article.

The technology works by using electricity from the grid to run a compressor, producing heated compressed air. Heat is extracted from the air stream and stored inside a proprietary thermal store preserving the energy for use later in the cycle. Compressed air is then stored in a purpose-built underground cavern, which is kept at a constant pressure using hydrostatic head from a water column. During charging, compressed air displaces water out of the cavern up a water column to a surface reservoir, and during discharge water flows back into the cavern forcing air to the surface under pressure where it is re-heated using the stored heat and then expanded through a turbine to generate electricity on demand.

An animation describing Hydrostor’s A-CAES system is available on YouTube.

I found the video worth watching, as it answered most of my questions.

Where Could Systems Be Installed?

This paragraph from the AESA article talks about the location of the energy store in South Australia.

By selecting the Terramin Angas Zinc Mine, the project will repurpose existing underground mining infrastructure as the A-CAES system’s sub-surface air storage cavern, benefiting both the electricity grid in South Australia and the local community by converting an unused brownfield site into a clean energy project that drives economic development. Hydrostor acknowledges Terramin Australia Limited’s support in developing the project and the technology’s beneficial application to South Australia.

I can think of a couple of mines in the UK, where such a system can be installed.

Conclusion

Hydrostor’s technology is standard process engineering, with all components and construction techniques well-proven in many decades of use.

I shall be watching Hydrostor with interest.

Contenders: Long Duration Energy Storage Technologies, And Who’s Behind Them

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

It is a must-read for anybody interested in the technology of storing energy.

There are certainly some companies, I will add to my watch list.
