Renewables/Energy Transition

Is the small fuel cell electric vehicle going to be a Betamax?

By decarbonising industrial and domestic heating, I am convinced that hydrogen has a significant role towards achieving net zero. However, the role of hydrogen in the passenger car sector is much less clear. I find it difficult to see how a hydrogen powered fuel cell electric vehicle (FCEV) can compete with a battery electric vehicle (BEV). That conclusion was reinforced by two recent reports from BloombergNEF and Volkswagen.

Home batteries to store solar power

The launch of a new battery for homes that can store solar power for use in the evenings is “another nail in the coffin of conventional utilities”, it has been claimed. Tesla announced it was launching the wall-mounted lithium ion rechargeable storage units, based on the batteries used in the company’s electric vehicles, at an event in California. Chief executive Elon Musk said: “Our goal here is to fundamentally change the way the world uses energy”, as he launched the new “powerwall” batteries, which are little bigger than a conventional boiler. The technology will cost between 3,000 and 3,500 US dollars (£2,000 - £2,300) and will start shipping in the US in the summer.
