Green Hydrogen Could Fill Big Gaps in Renewable Energy

When hydrogen burns, the only by-product is water—which is why hydrogen has been an alluring zero-carbon energy source for decades. Yet the traditional process for producing hydrogen, in which fossil fuels are exposed to steam, is not even remotely zero-carbon. Hydrogen produced this way is called gray hydrogen; if the CO2 is captured and sequestered, it is called blue hydrogen.

Green hydrogen is different. It is produced through electrolysis, in which machines split water into hydrogen and oxygen, with no other by-products. Historically, electrolysis required so much electricity that it made little sense to produce hydrogen that way. The situation is changing for two reasons. First,…

Renewable Hydrogen: Key to a New Civilization

The distinct geography of every part of the Earth provides each local community with its own set of renewable energy options to harness: some places get ample solar input, others wind, hydro, or geothermal power. Yet renewable energy, like the capricious weather, is variable and cannot always promise a constant supply of energy. Any electricity generated must be used as it is made. In other words, technology to store it is still lacking. Hence, when a thick cloud blocks the sun, solar power generation is halted for as long as the cloud is there. This is where hydrogen (H2) enters the renewable energy equation; not just as a possible technology of the future, but as a breakthrough technology.

The Gospel of Hydrogen Power

Mr. Strizki favors fuel-cell cars for the same reasons as most proponents. You can make fuel using water and solar power, as he does. The byproduct of making hydrogen is oxygen, and the byproduct of burning it is water. Hydrogen is among the most plentiful elements on earth, so you don’t have to go to adversarial countries or engage in environmentally destructive extraction to get it. The car is as quiet to drive as any other electric, it requires little maintenance, and because it doesn’t carry 1,200 pounds of batteries, it has a performance edge.

The Green Hydrogen Puzzle Is Starting to Fall Into Place

Replacing fossil fuels with green hydrogen in the economy is a bit like doing a jigsaw puzzle: Once a few early pieces are connected, it will be much easier to fit the others. A plan from one of the world’s top wind-turbine makers can help.

The Green Hydrogen Revolution Is Now Underway

One thing is certain – hydrogen is no longer a “niche” fringe fuel. The element will play a critical role in the decarbonization of sectors where electrification is not possible, with fortunes to be built along the way.

This company may have solved one of the hardest problems in clean energy

It is an odd twist of chemistry that there is fuel embedded in the most common substance on earth: water. And it is the most abundant chemical element in the universe, so you’d think we’d have all we need. Sadly, it’s not that easy.

Why We Need Green Hydrogen

So, what is green hydrogen? Simply put, it is hydrogen fuel that is created using renewable energy instead of fossil fuels. It has the potential to provide clean power for manufacturing, transportation, and more — and its only byproduct is water.
