Energy Bill [HL]

Baroness Bloomfield of Hinton Waldrist Excerpts

Report stage
Tuesday 28th March 2023 Lords Chamber

[Baroness Blake of Leeds (Lab)]

I thank the noble Lord for bringing this information to our attention. Some interesting reports documenting the risks are available, and I refer particularly to the report from the Institution of Fire Engineers on solar power fire risk and to batteryfiresafety.co.uk.

I have a couple of points to add to the comments already made as to whether it would be worth directing information about the storage of the batteries. It should be highlighted in particular that batteries are often stored in garages next to parked cars, which can have similar battery systems, and will not always be easily accessible.

The risks of lithium ion batteries from a fire safety perspective apparently have been well documented. However, the other element is that the risk with lithium ion batteries is not just fire. Once the battery fails—I think the term is “runs away”—the cells usually start to give off smoke. Thermal runaway is the chemical process within the battery which produces heat, as well as flammable toxic chemical gases, very quickly, often before any flames arise.

I think it is fair to say that, although the information is out there, it has not been properly documented. I wonder whether the health and safety considerations of the increasing use of these batteries and solar panels have been taken on board. Does the Minister think that there is a problem and, if the answer is yes, what does she propose to do about it?

[Baroness Bloomfield of Hinton Waldrist (Con)]

My Lords, I thank the noble Lord for his amendment on requesting a report into the fire risks of photovoltaic panels, lithium ion battery storage facilities and similar technologies. I was delighted to hear of his welcome in the Budget for the VAT exemptions.

First, I reassure the noble Lord that the health and safety regimes surrounding net-zero technologies are a priority for the Government. All electrical equipment requires safe installation and use. The Government recognise the importance of net-zero technologies such as electricity storage and solar PV in their ability to help us to use energy more flexibly and decarbonise our electricity system cost-effectively.

The data collected so far indicates that the risk from solar PV fires is low. However, it is right that we work with the industry to understand why any incidents happen and help to stop future occurrences. Over a three-year period and an overall cost of £135,000, the Government commissioned the Building Research Establishment to develop new guidelines for PV system installers, designers and the fire services, with the aim of making solar PV even safer. In February this year, the RISC Authority, the Microgeneration Certification Scheme and Solar Energy UK published an updated joint code of practice on recommendations for fire risk prevention in UK solar systems. Grid-scale lithium ion battery energy storage systems are covered by a robust regulatory framework, which requires manufacturers to ensure that products are safe before they are placed on the market and installed correctly, and that any safety issues found after products are on the market or after installations are dealt with.

In 2018, the Government set up an industry-led electricity storage health and safety governance group, which is responsible for ensuring that an appropriate, robust and future-proofed health and safety framework is sustained as the industry develops and electricity storage deployment increases. The Government are currently working with the group to support the development of a product and installation publicly available standard for domestic small-scale battery storage and guidance for grid-scale storage. They will both be published this year.

Most of the specific issues of e-scooters and bicycles fall within the remit of the Office for Zero Emission Vehicles, and I shall ask it to write to the noble Lord. I can also confirm that Defra will soon publish a consultation on battery recycling.

I do not believe that a specific report on fire risk of photovoltaic panels, lithium ion battery storage facilities and similar technologies mandated by the Secretary of State is necessary. While I welcome the noble Lord’s intention, we believe that working alongside industry and the fire services to manage specific risks is the appropriate way forward. It ensures that these vital technologies are installed, operated and decommissioned in a safe way, while still delivering the best outcomes for consumers. I hope that the noble Lord can recognise the Government’s sustained commitment to enabling the deployment of net-zero technologies in a safe and sustainable way.

In addition, on the concerns expressed by the noble Baroness, Lady Blake, about lithium ion batteries and their ability to combust, I visited last week a very clever packaging firm called Tri-Wall in Monmouth, which has developed packaging specifically for lithium ion batteries to be transported by air safely. The packaging itself will detect any change in heat in the batteries that it contains and change the structure of the packaging into water that will put the fire out before it even gets out of the packaging. Very clever technologies are being developed specifically around lithium ion battery transport and storage.

I hope that, with those few reassuring remarks, we can ask the noble Lord to withdraw his amendment.

[Lord Foster of Bath (LD)]

My Lords, the time is late; I shall be very quick indeed. I was well aware, of course, of the work that has been done looking at the package of arrangements around solar panels and their batteries. I really wanted to use it as a peg on which to hang the wider issue of all forms of lithium batteries, in particular. I am pleased to hear about the 2018 established group. It would be very helpful if we could see some of the output of that. I am grateful, too, to hear that there are going to be new standards, but the truth is very simple: you can have all the standards you like, and the products may be okay, but if they are not used appropriately and not decommissioned appropriately, then real problems exist, and that is what is happening. There are a huge number of fires in our landfill sites because people are not doing what they are meant to do in disposing of batteries. We have to find a way forward. That is why I wanted a report. I am disappointed that the Minister is not prepared to go further, but at this stage I beg leave to withdraw the amendment.
