Can hydrogen change the global clean energy landscape?

hydrogen technology

Hydrogen is the most abundant element in the universe, but in its gaseous form is very rare on Earth; it exists mostly in the form of chemical compounds such as water, hydrocarbons and generally speaking organic matter. That means that we need to employ industrial processes to produce useable hydrogen gas. Currently, the most commonly used process is reforming of natural gas – 95% of the hydrogen now generated in the United States is produced using this method. Unfortunately, this process also produces carbon emissions, which are released into the atmosphere – unless relatively costly carbon capture, utilization, and storage (CCUS) solutions are employed.

While it hasn’t yet seen widespread adoption, another method of cleaner hydrogen production exists: electrolysis. By using green energy to electrolyze water, hydrogen gas is produced, with only oxygen as a by-product. While inroads are being made into industrial-scale production of hydrogen by electrolysis, costs can remain prohibitive. However, as renewable energy becomes more efficient and less costly, industrial electrolyzing technology and waste to energy technologies become more readily available, along with increasing global pressure to decarbonize, we are likely to see green hydrogen production become more widely adopted in the coming years.

Hydrogen has many advantages as we push toward a greener and more decarbonized industrial global society. As a fuel source, it is significantly more energy-dense than electric batteries. While personal and commercial electric vehicles have seen widespread adoption in recent years, batteries still don’t carry sufficient charge in relation to weight to allow for practical use in longer-distance transportation such as long-haul trucks, ships and air transport. In addition, batteries take a significant time to fully charge.

Advances in hydrogen fuel production technologies could begin to address some of these issues.

Hydrogen also has the potential to supplement or even replace the natural gas which is currently widely used for home heating in North America, Europe and parts of Asia. While replacing natural gas with electrical heating could be costly, and has the potential to tax electricity generation and distribution capacity during cold periods, utilizing hydrogen as either an additive to natural gas or eventually as the sole fuel could be achieved more efficiently.

If major natural gas producing nations – such as countries in the Middle East – do start switching to hydrogen, the way could be paved for a smoother, swifter and more realistic transition to a global hydrogen economy.

At Clean Energy Enterprises we see this approach being combined with the development of cleaner, renewable hydrogen production solutions. Advanced Gasification efficiently breaks down organic matter molecules to isolate hydrogen gas and recover it, in an environmentally safe manner. That will help to tackle our considerable organic waste and biomass disposal issues – that is, clean waste-to-energy solutions that deliver a win-win outcome.

Is Hydrogen Technology on the Verge of Breakout?

Lithium-ion battery technology is leading the zero-emission transportation industry.

But you ignore the hydrogen fuel cell market at your own peril.

That’s because hydrogen fuel cell sales could easily DOUBLE… then TRIPLE… then grow MANY more times over.

Hydrogen’s Potential

The Hydrogen Council forecasts that by 2050, hydrogen will power more than 400 million passenger cars worldwide and up to 20 million trucks and 5 million buses.

It expects hydrogen technologies to provide 18% of the world’s total energy needs by that time, with the annual sales generated from the hydrogen fuel cell market reaching $2.5 trillion while creating 30 million jobs globally.

That’s quite a move for the market from here. But it’s not an impossible one.

According to the U.S. DOE, as of February 2019, there were only 6,558 hydrogen fuel cell vehicles in America. That’s virtually nothing. But there are pretty good reasons for low sales number today — and good reasons to expect sales to increase many times over.

First, it’s important to remember that hydrogen fuel cell vehicles are not available in every area. It’s very unlikely that you personally live near a dealer that sells a hydrogen fuel cell car. You could buy one, of course, but you’d most likely have to ship it to your house.

And then there’s a serious lack of infrastructure. As of March 2019, there are only 39 hydrogen refueling stations in the U.S., 35 of which are in California.

Both of these factors play a major role in low sales right now.

However, it’s also very important to remember that hydrogen fuel cell technology is still developing.

The cost of producing hydrogen fuel cells has dropped significantly over the past several years. And forecasts show further declines, but costs are still quite high. That makes retail prices for hydrogen fuel cell vehicles higher than their lithium-ion battery-electric counterparts.

Toyota just recently began a promotion to sell its hydrogen fuel cell Mirai for just $50,000 — and that’s with a $20,000 government subsidy.

Tesla’s Model X currently starts over $80,000. But that’s its luxury model. Tesla’s Model 3, which is comparable to the Mirai in luxury, starts around $35,000.

So that’s another thing holding sales back.

But aside from production and consumer costs, hydrogen fuel cells don’t really have a lot of serious support from many major automakers… right now at least.

See, the science behind the case for hydrogen fuel cells is hard to argue against. The energy density of hydrogen is far higher than any lithium-ion battery, making for faster refueling and longer range.

But in terms of overall efficiency, lithium-ion battery-electric is a bit better. And that has a lot to do with hydrogen production.

Even though hydrogen is the most common element in the universe, it’s usually bonded with something else… like oxygen to make water. And producing hydrogen for fuel is very energy intensive and expensive, as is storing it. This results in high costs at the hydrogen pump for consumers.

YouTube channel Real Engineering found it costs between $10 and $12 to recharge a Tesla Model 3. With that, they got a range of 500 km (310 miles) for a fuel efficiency of about $0.020 to $0.024 per km.

Comparatively, they filled up a Toyota Mirai for $85 and were able to drive 480 km (300 miles) for a fuel efficiency of $0.171 per km.

So for the consumer, a lithium-ion battery electric vehicle makes a lot more sense… but againright now.
