Green hydrogen to cost less than natural gas-based alternatives by 2050

first_imgGreen hydrogen should outcompete natural gas-based alternatives without CCS by 2050, says BNEFHigh hopes have been pinned on hydrogen to drive decarbonisation across heavy-polluting sectors like industry and transport, by providing an alternative to traditional, carbon-intensive fuels such as diesel and petrol.And as the price of renewable-generated electricity continues to decline and becomes increasingly competitive with fossil fuels like coal or natural gas, the financial incentive to prioritise green hydrogen is growing stronger, allowing this nascent industry to achieve the benefits of scale – provided sufficient policy support is given.BNEF’s analysis reveals that its green hydrogen cost forecast is now expected to be 13% lower in 2030 than in its previous outlook, and 17% lower in 2050. It anticipates costs will now fall “well below” $2 per kilogram by 2030 and $1 per kilogram by 2050 in most markets.“By 2030, it will make little economic sense to build ‘blue’ hydrogen production facilities in most countries, unless space constraints are an issue for renewables,” said Tengler.“Companies currently banking on producing hydrogen from fossil fuels with CCS will have at most 10 years before they feel the pinch. Eventually, those assets will be undercut, like what is happening with coal in the power sector today.”The report highlights that renewable hydrogen should outcompete natural gas-based alternatives without CCS by 2050 in all 28 modelled countries and that it would even cost less than natural gas on an energy-equivalent basis in 15 of those markets.Its updated forecast on the levelised cost of renewable electricity (LCOE) is the main driver of the drop in the LCOH2 projection. The marker researcher expects the average levelised cost of solar PV to be 40% lower by 2050 than it predicted two years ago.The cost of electricity will account for the majority of the cost of producing green hydrogen by 2030, with electrolyser-related costs accounting for the rest, according to BNEF. By 2050, it anticipates the share of LCOH2 driven by electricity should approach 90% when made from onshore wind.
