The solid-state battery market will grow to $8 billion by 2031, IDTechEx forecasts. With the larger electrochemical window of solid electrolytes – as opposed to liquid ones in lithium-ion batteries – high voltage cathode materials can be used. High-energy-density lithium metal anodes can push the energy density beyond 1,000 Watt-hours per litre (Wh/L).
Hydrogen fuel cell technology is making in-roads at the Friedrichshafen plant of Rolls-Royce's Power Systems where a 250 kW demonstrator is being set up for testing. At the PowerLab, four low-temperature polymer electrolyte membrane (PEM) fuel cells are ready, containerised with separate compartments for fuel cells and batteries.
Mitsubishi Heavy Industries (MHI) has decided to absorb the business of Mitsubishi Power effective October 1, 2021. Some aspects of the integration are already underway, as the Japanese manufacturer strives to promote the use of carbon-free fuels like hydrogen and ammonia at various demonstration plants around the world.
The Port of Rotterdam plans to take a financial investment decision on its H-Vision project this year, with a view to producing hydrogen from natural gas and refinery fuels gas by the end of 2026. Such fossil fuel-based, “blue” hydrogen projects, however, do not enjoy the same support as “green” hydrogen projects, based on renewables.
