Researchers just discovered a massive 'jacuzzi bubbling with almost pure hydrogen' — a lucrative source of clean energy

• A team of researchers recently discovered a massive reservoir of hydrogen in a mine in Albania.
• Its concentrations of hydrogen are so high that it has caused explosions and killed miners.
• The reservoir could be a potential source of clean hydrogen energy.

Hydrogen is becoming a favorable alternative to fossil fuels because it doesn't release carbon into the environment when burned. The downside is that generating it has long been an energy-intensive business that emits greenhouse gasses that warm the planet.
