Harboursandport.com: Norway, 14 June 2022 – Hydrogen has a crucial role in decarbonizing the world’s energy system, but uptake will be too slow. Governments need to make urgent, significant policy interventions, according to a new report by DNV.
In Hydrogen Forecast to 2050, DNV predicts the amount
of hydrogen in the energy mix will be only 0.5% in 2030 and 5% in 2050.
However, to meet the targets of the Paris Agreement, hydrogen uptake would need
to triple to meet 15% of energy demand by mid-century.
Group President and CEO of DNV, Remi Eriksen, said “Hydrogen is
essential to decarbonize sectors that cannot be electrified, like aviation, maritime,
and high-heat, and should therefore be
prioritized for these sectors.”
“Policies do not match hydrogen’s importance. They will also need to
support the scaling of renewable energy generation and carbon capture and
storage as crucial elements in producing low-carbon hydrogen.”
According to Hydrogen Forecast to 2050, electricity-based
green hydrogen – produced by splitting hydrogen from water using electrolysers
– will be the dominant form of production by the middle of the century,
accounting for 72% of output. This will require a surplus of renewable energy,
to power an electrolyser capacity of 3,100 gigawatts. This is more than
twice the total installed generation capacity of solar and wind today.
Blue hydrogen – produced from natural gas with emissions captured – has a
greater role to play in the shorter term (around 30% of total production in
2030), but its competitiveness will reduce as renewable energy capacity
increases and prices drop.
Global spending on producing hydrogen for energy purposes from now until
2050 will be USD 6.8tn, with an additional USD 180bn spent on hydrogen
pipelines and USD 530bn on building and operating ammonia terminals, according
to DNV’s forecasts.
Cost considerations will lead to more than 50% of hydrogen pipelines
globally being repurposed from natural gas pipelines, as the cost to repurpose
pipelines is expected to be just 10-35% of new construction costs. Hydrogen
will be transported by pipelines up to medium distances within and between
countries, but not between continents. Global hydrogen trade will also be
limited by the high cost of liquefying hydrogen for ship transport and the low
energy density of hydrogen. The hydrogen derivative ammonia, which is more stable
and can be more readily transported by ship, will be traded globally.
Early uptake of hydrogen will be led by hard-to-abate, high-heat
manufacturing processes such as iron and steel production which currently use
coal and natural gas. Hydrogen derivatives, such as ammonia and methanol, are
key to decarbonizing heavy transport like shipping and aviation, but these
fuels won’t scale until the 2030s according to DNV’s forecasts.
Hydrogen will not see an uptake in passenger vehicles, and only limited
uptake in power generation. Hydrogen for heating buildings will not scale
globally but will see early uptake in some regions that already have extensive
gas infrastructure.
“Scaling hydrogen value chains will require managing safety risk and
public acceptance, as well as employing policies to make hydrogen projects
competitive and bankable. We need to plan at the level of energy systems,
enabling societies to embrace the urgent decarbonization opportunities
presented by hydrogen,” added Eriksen.
The uptake of hydrogen will differ significantly by region, heavily
influenced by policy. Europe is the forerunner with hydrogen set to take 11% of
the energy mix by 2050, as enabling policies both kickstart the scaling of
hydrogen production and stimulate end-use. OECD Pacific (hydrogen 8% of the energy
mix in 2050) and North America (7%) regions also have strategies, targets, and
funding pushing the supply-side, but have lower carbon prices and less concrete
targets and policies. Greater China (6%) follows on, recently providing more
clarity on funding and hydrogen prospects towards 2035, coupled with an
expanding national emissions trading scheme. These four regions will together
consume two-thirds of global hydrogen demand for energy purposes by 2050.
