Hydrogen Energy Outlook: Bridging the Gap from 5% to 15%

·5 min read

Giving hydrogen a larger role in the global energy mix is critical to reaching goals set by the Paris Agreement but doesn’t come without its share of risks, experts in DNV’s Hydrogen Forecast to 2050 webinar said on June 14.

“Hydrogen seems to be everywhere and nowhere,” DNV group president and CEO Remi Eriksen said in the webinar. “A lot of people are talking about the big role hydrogen can take in the energy transition, but the amount of low-carbon, renewable hydrogen produced today is very, very small.”

According to DNV’s report, hydrogen should comprise 15% of the global energy mix by 2050 but is currently projected to make up only 5%. Eriksen also noted that in terms of delegating clean energy sources, hydrogen should only be used for hard-to-abate sectors such as aviation, maritime and high-heat manufacturing.

“Throughout our forecast period and beyond, hydrogen will remain more costly and less efficient than direct electrification,” he said. “It is a precious resource that must be applied wisely and only for [sectors] that cannot be electrified.”

Ulrik Olbjørn, project manager for low carbon solutions at Equinor, echoed these financial concerns later in the webinar, imploring governments to stop giving false hope to the industry by saying the energy transition would be cheap. “The transition will be quite costly,” he said.

Cost considerations are only one of several hurdles in the way of achieving the 15% goal, including consumer safety concerns, but DNV is remaining optimistic.

“We've moved already from negligible role for hydrogen to 5%, and I think to go from nothing to 5% to 15%, I think it's almost easier to scale 5% to 15% than it is to go from 0% to 5%,” Hari Vamadevan, U.K. vice president at DNV, told Hart Energy.

Safety’s important role

To develop a hydrogen ecosystem, governments and corporations must work together to gain the trust of the consumer, develop infrastructure for hydrogen delivery, create a scale of hydrogen production and implement government incentives to develop the hydrogen value chains.

Due to its higher flammability, consumers are much more hesitant of increasing the amount of hydrogen in the global energy mix than they are of using LNG and other natural gas products. DNV is working to paint a more positive picture of hydrogen and its helpful qualities through its research facility in northern England.

“Because hydrogen is so crucial for decarbonization for the hard-to-abate sectors, we cannot allow safety to become its Achilles heel,” Eriksen said. “Hydrogen shares many properties with natural gas, but it does have some unique properties likes its higher explosion reactivity.”

At its Spadeadam, U.K.-based research and testing facility, the company is working to improve safety conditions for hydrogen transport through “extensive physical testing,” through which researchers have determined where to concentrate hydrogen efforts.

In addition to the testing facility, DNV also built Hy Street, a row of houses in which the U.K. government experiments with the use of hydrogen as a replacement for residential and commercial natural gas-run appliances.

“Methane is 5% to 15% [flammable]; hydrogen is 4% to 75%. So making hydrogen safe is completely possible, and it's something that DNV is playing a big part in,” Vamadevan said. “Developing that safety case for hydrogen is an important part of the overall development of the energy ecosystem and in the U.K.”

Group effort

According to the Hydrogen Forecast report, it’s predicted that $129 billion U.S. dollars (USD) globally will go to investing in hydrogen by 2030 and $440 billion by 2050, with even more to come in the second half of the century. This is a substantial increase from the $12 billion invested in hydrogen last year.

As 2050 draws closer, DNV analysts predict that the cost of producing green hydrogen will fall to a global average of $1.50/kg USD by 2050, eventually becoming cheaper than blue hydrogen and surpassing it in production.

Although the world is predicted to favor green hydrogen as it becomes more economically sustainable, that doesn’t render blue hydrogen obsolete as the energy transition transpires. Rather than serve as a short-term solution, blue hydrogen will remain important at least through the forecasted period.

“There’s going to be a series of mini transitions, and that’s the best way to look at the energy transition and to look at hydrogen,” Vamadevan said. “It’s not something versus something else, it’s actually all of these things happening. It’s just a question of timing.”

In order to raise the necessary capital to make green hydrogen more accessible, stronger governance is required through enabling policies and creating direct subsidies, Eriksen said.

However, all facets of the industry, from national governance to consumers, are required to work in tandem to achieve these goals. The responsibility of growing hydrogen’s presence in the global energy mix can’t fall solely to governing bodies, Vamadevan said.

“There is no net zero without hydrogen, and therefore if the governments provide the framework, I think industry can step up, and that's really the key,” he continued. “It's that partnership between government and business, and then let's not forget to take the consumer on along the ride with us.”
