The dream of a future with hydrogen powered transportation is finally turning into reality, as companies like Hyundai launch vehicles using a technology that delivers its main emission as water vapor.

California is leading the way to provide fertile ground for hydrogen vehicles but the long term viability of hydrogen remains in doubt: there's a need for technological advancements and critical infrastructure that goes far beyond the just vehicle, suppliers, and service points.

The second Climate Deal Day (CDD) brought together businesses and entrepreneurs such as Hara and The Long Run Venture, change agents such as 10:10 and the Carbon War Room, and government innovators such as the City of London s Food Board for a day of collaboration and deal-making
