GKN Hydrogen stores electricity using a metal hydride system

By Julian Singer Hydrogen is often considered as a means for storing electricity, using electrolysers to make the hydrogen and fuel cells to convert it back to electricity. However, there are two downsides to using hydrogen for storage: it has very low density, so that in practice you either need a large underground cavern or, [...]

Form Energy aim to reduce the cost of electricity storage by a tenth

By Julian Singer The desperate need to store electricity has stimulated the development of some surprising techniques. One of these is based on the rusting of iron. The basic principle is that electrons are produced when iron rusts in the presence of water and oxygen. Conversely, if an electrical current is applied to rust the [...]

Natural (gold) hydrogen

By Julian Singer On 7 June, at one of the Oxford Energy seminars, Dr. Chris Ballentine gave a fascinating talk entitled “Natural (gold) Hydrogen – Pipeline or Pipe dream?”. Gold hydrogen is hydrogen that occurs naturally in the earth’s surface. How wonderful if we could just drill for it like methane! The idea seemed absurd [...]

Tees Valley Lithium aims to build the first UK lithium processing plant

By Julian Singer Tees Valley Lithium (TVL) aims to build what it claims will be the first major low carbon Lithium Hydroxide (LIH) plant in the UK. Currently there are no LIH plants in Europe, even though it is the principal form of lithium required by battery manufacturers, in particular those using the most popular [...]

Clean Power Hydrogen starts to sell its electrolysers and lists on AIM

By Julian Singer Clean Power Hydrogen, or CPH2, manufactures a membrane-free electrolyser to produce so-called green hydrogen from electricity and water. The company was founded in Ireland in 2012 by Dr Nigel Williamson and Joe Scott but established its headquarters in Doncaster in 2018. Dr Williamson had worked for ITM Power, the leading UK electrolyser [...]

AMTE focuses on product development and scaling-up but its share price suffers

By Julian Singer AMTE Power, the Thurso-based manufacturer of lithium-ion and sodium-ion batteries, marked the first anniversary of its AIM listing in February. Its shares were sold for 175p at the initial public offering but have dropped steadily since then to their present value of 90p. This is disappointing, given the need for energy storage [...]

A Norwegian manufacturer of electrolysers with a long history

By Julian Singer Nel ASA is a Norwegian company that claims to be not only the first but also the largest manufacturer of electrolysers in the world. It started as a part of Norsk Hydro in 1927 at a time when Norway was beginning to devote some of its huge potential for hydroelectric power to [...]

Hydrostor’s solution to large scale electricity storage

By Julian Singer The need for electricity storage has produced a bewildering array of different companies using different techniques. There are many ways in which they can be classified, one of which is by their capacity to store electricity. Small cells, such as lithium-ion, can of course be duplicated but generally become uneconomical beyond a [...]

British Lithium makes a radical advance

By Barney Smith It is well known that Lithium is a soft, silver-white, chemical element with the symbol Li and atomic number 3, which means that it is the least dense metal and solid element within the alkali metal group on the periodic table. In nature, lithium occurs only in compounds, due to its high [...]

How to develop a new storage system according to Donald Sadoway

By Julian Singer Donald Sadoway is a professor of chemistry at MIT. He has been known for his animated lecturing style for a number of years, but more recently he has given several entertaining talks promoting electricity storage using liquid metal batteries[1]. These talks focus not so much on the technology but on how to [...]
