Hydrogen can be integrated into industrial processes to reduce carbon emissions.
As we shift towards a clean energy future, the role of utility hydrogen is becoming increasingly important. Hailed as a key player in slashing emissions across various sectors, especially those tough-to-clean industries, utility hydrogen stands out. It’s not just a sidekick to renewable sources like solar and wind but a star in the energy game. However, making the leap to a hydrogen-powered world isn’t without its bumps in the road.
Challenges of Scaling Up
Companies today understand the need for utility hydrogen, and it sparks hope for a cleaner energy shift. Hydrogen is catching on faster with the announcement of Hydrogen Hubs and incentives from the Biden Administration. These hubs are places where hydrogen production, storage, and distribution come together in harmony. The Pacific Northwest is an example area on the frontlines, hoping to use its bounty of renewable energy for producing renewable hydrogen.
But making hydrogen energy widespread enough to meet global needs is tough. We can’t just take our natural gas setup and swap in hydrogen gas—it’s not that simple. Hydrogen’s tiny molecules can cause pipes to crack and leak, which means we need to spend some serious cash to get our infrastructure hydrogen-ready and start with distributed hydrogen solutions in the meantime.
Technical Hurdles for Utility Hydrogen
Creating green hydrogen by electrolysis, which is powered by renewable electricity, is where companies like Siemens Energy and Mitsubishi Power are focusing their efforts. Yet, electrolysis needs to get more efficient and less pricey to be practical on a larger scale.
Storing hydrogen is tricky, too. It’s not dense in energy by volume, which means we can’t store or move it far without some creative solutions. We’re talking about things like metal hydrides or squishing it under high pressure to make it work.
Costs and Market Factors
Clean hydrogen, particularly green hydrogen production, still costs a pretty penny, more than fossil fuels. That’s a big hurdle for energy companies like Xcel Energy and Duke Energy, who have to think about keeping energy costs down for folks while also cleaning up their act.
Hydrogen projects are popping up all over the place, but whether they make financial sense hinges on the cost of renewable power, the cost of the gas feedstock, and the tech used to make the hydrogen. That’s where the European Hydrogen Bank and other finance opportunities come in, helping fund the research and development needed to make hydrogen a budget-friendly option.
Policy and Regulation
We can’t talk about the hydrogen transition without acknowledging the governments and regulators shaping it. They can speed things up by offering incentives for low carbon hydrogen, backing solid carbon capture for turquoise hydrogen production, and dedicating money to infrastructure. Groups like the Hydrogen Council are pushing for policies that help us move from today’s tech to the hydrogen-fueled world we want.
Environmental Impact
Hydrogen’s clean when it’s in use, like in fuel cells, but certain ways of making it, such as making grey hydrogen from natural gas, still spews out carbon dioxide. Companies like Bloom Energy are on a mission to cut carbon emissions from the whole hydrogen production process, but there’s still a way to go before we can call it totally clean.
Looking Forward
In wrapping up, utility hydrogen’s place in our clean energy picture is pretty solid. Mixing hydrogen into our gas utilities, rolling out hydrogen fuel for mobility and fleet fueling, and aiming for a full-on hydrogen economy are all on the table.
It’s only by facing these challenges head-on that utility hydrogen can live up to its potential as a sustainable, versatile power source for a world with zero emissions.
