$1/kg Hydrogen With E-TAC High-Efficiency Electrolysis

Israeli company H2Pro claims its highly efficient water-splitting technology will deliver green hydrogen at less than US$1 per kilogram before 2030. That’s a big deal; it would represent a 60-80 percent drop in green H2 prices, down to a level where it’s cheaper per unit of energy than current retail gasoline prices in the United States. The Hydrogen Council’s current projections don’t expect that kind of price drop until 2050, and even then it’s a best-case scenario.

[] – H2Pro’s dollar-a-kilo green hydrogen: a 20-year leap in clean energy?

Note that 1 kg of hydrogen contains about 3 times as much energy as 1 kg of gasoline. Additionally, hydrogen can be converted into kinetic energy at an efficiency of up to 60%, where gasoline scores merely 25% at best.

Some caution is well-advised here, as small start-ups are almost forced to be loud in order to attract investment capital. But the development is interesting, nevertheless, because of the pursuing of yet another technological approach. Eventually, the best methods will float to the top.

Electrolytic hydrogen production faces technological challenges to improve its efficiency, economic value and potential for global integration. In conventional water electrolysis, the water oxidation and reduction reactions are coupled in both time and space, as they occur simultaneously at an anode and a cathode in the same cell. This introduces challenges, such as product separation, and sets strict constraints on material selection and process conditions. Here, we decouple these reactions by dividing the process into two steps: an electrochemical step that reduces water at the cathode and oxidizes the anode, followed by a spontaneous chemical step that is driven faster at higher temperature, which reduces the anode back to its initial state by oxidizing water. This enables overall water splitting at average cell voltages of 1.44–1.60 V with nominal current densities of 10–200 mA cm−2 in a membrane-free, two-electrode cell. This allows us to produce hydrogen at low voltages in a simple, cyclic process with high efficiency, robustness, safety and scale-up potential.

H2Pro’s E-TAC hydrogen production system promises a revolutionary jump in water-splitting efficiency, and a 20-year plunge in the cost of clean hydrogen.

Charging a Car Battery in 5 Minutes

German language video

German battery giant Varta plans to enter the lucrative market for e-vehicles and claims to have a battery, with which a car battery can be charged within 6 minutes. If that were the case, the victory of the battery over alternative power forms, like hydrogen, would almost be certain.

Varta is not alone, competitors in the rapid-charging segment are Tesla and the Israeli company StoreDot. StoreDot expects market introduction of their “5 minutes product” by 2024; the company can point to cooperation with BP, Samsung and Daimler, as well as the large Chinese battery company EVE Energy. The architecture of the new battery is relatively simple and based on nanotechnology. Existing production lines for lithium-ion-batteries can be retrofitted.

It looks as if the battery technology will be a few years ahead of the required charging infrastructure, able to deliver 150 kW or more. Perhaps it would be a good idea to bury new power lines next to highways, to cope with the to be expected strong increase in demand for electricity for transport purposes. Build charging stations along the highway, replacing gasoline fuel stations. This would eliminate the need to have hundreds of thousands of charging points, littered all over the country. In this way, the conventional grid could be kept separate from the “highway grid”.

120 MW CAES Storage in Israel

The Israeli company Augwind is building a CAES air battery to the tune of 120 MW. The battery is said to operate at an overall efficiency of 75-81%. Energy input will come from pv-solar.

Calculations conducted so far have shown the installed cost of long-duration storage to be one-tenth of the cost of lithium-ion battery storage.

Stand Alone Solar Water Splitting


The current favored approach to large-scale storing of renewable electricity is feeding the electric energy to a separate electrolyzer. There are however photoelectrochemical (PEC) hydrogen generation technologies, that convert solar radiation into hydrogen in a more direct fashion.

Red Sea-Dead Sea Pipeline Decided Upon


Israel & Jordan need water and decided to implement a decades old plan, namely to transport water from the Red Sea to the Dead Sea via a canal.


  • Volume: ca. 300 million m3/year.
  • Desalinization: 65-85 million m3/year.
  • Cost: $800 million.
  • Length: 180 km
  • Red Sea loses 700 million m3/year
  • Partners: World Bank, US, EU countries
