Study finds direct seawater splitting has substantial drawbacks to conventional water splitting, offers almost no advantage

Green Car Congress

A study by a team of researchers from Technische Universität Berlin (TUB) and Fritz-Haber-Institut der Max-Planck-Gesellschaft has found that direct seawater splitting for hydrogen production has substantial drawbacks compared to conventional water splitting and offers almost no advantage. Additionally, H 2 O is needed for water splitting.

Wärtsilä gas engines to burn 100% hydrogen

Green Car Congress

During the energy sector’s transition to carbon neutrality, wind, solar, and battery storage will form an increasing share of power systems. There will, however, also be a need for renewable fuels to enable long-term storage in persistent low wind and solar weather conditions.

In Norway, Asko begins piloting use of hydrogen fuel-cell trucks

Green Car Congress

Electricity generated by solar panels installed across nine thousand square metres of roofing at Asko’s regional warehouse is being used to split water, producing emissions-free hydrogen fuel and oxygen. In addition to solar, Asko is a major industrial wind power producer.

Researchers develop two-step method for efficient decoupled water splitting

Green Car Congress

A team of researchers in Israel has developed a two-step electrochemical-chemical cycle for decoupled water splitting with high efficiency. In the two-step electrochemical–thermally activated chemical (E-TAC) cycle process, water is reduced to hydrogen gas at the cathode, liberating OH – ions. —Dotan et al. 2H 2 + O 2.

U of Melbourne team demonstrates direct hydrogen production from air; direct air electrolysis (DAE)

Green Car Congress

Researchers at the University of Melbourne (Australia) have demonstrated a method of direct hydrogen production from air— in situ capture of freshwater from the atmosphere using hygroscopic electrolyte and subsequent electrolysis powered by solar or wind with a current density up to 574 mA cm ?2.
