Dave Elliott: While some people see hydrogen as a key energy vector for the future, others do not, claiming that its benefits have been oversold. ‘Much of the hype for hydrogen is coming from the oil and gas sector, in the hope that gullible politicians, seduced by an unattainable vision of limitless green hydrogen, will subsidise the vast investments needed to capture the emissions from gas-powered hydrogen. Their motivation couldn’t be clearer: to postpone the inevitable decline of their industry’. So says Jonathon Porritt in the Guardian. The battle is clearly on in terms of what type of hydrogen is to be produced and stored. For example, in the UK, the HyNet North West project has been given £72 million of funding for the production of blue hydrogen from natural gas and linked carbon capture and storage infrastructure. But at the same time Centrica is looking to large scale cavern storage of hydrogen – although that’s likely to be blue hydrogen, at least initially. Meanwhile, ITM Power, Orsted and Siemens are working on a green hydrogen ‘power to gas’ project, using power from offshore wind, and there are also plans for using an underground salt cavern hydrogen store. It is all new pioneering stuff, with plenty of room for technical problems and economic uncertainties, but that’s what innovation is all about.
