Background
Compact hydrogen storage hazard free, in operative quantity at mild conditions for personal cars, had been practically unsolvable problem, so hydrogen economics and hydrogen energy there are not in practice for personal cars till now, but in scientific dreams only.
Really, direct storage in a car for 1000 km mileage, even if with very energy effective H2-air FC and an electric mover per a wheel, needs about 9 kg hydrogen, and even if under enormous big pressure (let be 700 atm.), it would be enormous big tank of 220 liter (42 kg/m3, and it is very hazard deal.  A little more adequate science research is a porous containers of gaseous hydrogen, being compact, but it needs cryogenic about 100 K, slightly higher only, than its deep T evap. = 20 K (see [1] )

One of much more practical solutions was published by me yesterday, 22.02.2020 ([2] - “About non hazard usage of very dangerous hydrogen, https://judbarovski.blogspot.com/2020/02/  ).   


It is a compact storage - 110 kg/m3, or 50 kg = 3 * 16 kg = 3 * 23 liter for 1000 km mileage, but at normal temperature and 20 atm., and hazard free  vs. [1] with 70 kg/m3, 130 liter at 25 atm., but at cryogenic temperature, being very unsuitable for cars practice.

My above mentioned technology is a very interdisciplinary, considering wide environment of problems of hydrogen economics and hydrogen energy. Non hazard hydrogen storage and its usage were a small part of them, but a key part.
And porous container for compact ammonia storage at normal temperature and pressure can be interested innovation in a frame of whole system, was described in [2] . Moreover, it allows our hydrogen to store and use at wide range of T and P conditions, can be simply adjusted for different kinds of fuel calls and their variable operational needs.

Progressive city-car realization and powering-Updated,#1

Progressive city-car realization and powering-Updated, #1 Author: David Judbarovski, principle inventor, retired engineer, Israel judbarovski@gmail.com   Short CV: https://www.linkedin.com/in/david-judbarovski-1390944a/ Archive since 2017 yr: http://judbarovski.blogspot.be Archive since 2006 yr.: http://judbarovski.livejournal.com [3791]-3/11/2017,   My three levels’ conception of progressive transportation was disclosed in http://www.judbarovski.blogspot.co.il/2017/05/progressive-transportation-manifesto.html  (Progressive transportation manifesto, May 02. 2017). Its first level is a city-car.   Special designed city-car is a car moved electrically and equipped by very small battery as a city-grid element, and it isn’t big news now. Such cars are to be much cheaper and simpler than conventional cars and save a lot of energy. But I can suppose strictly to reject all sorts of powering them from underground, because it is energy ineffective and creates additional

Equipment for Short Take-off and Landing (E-STOL)

Equipment for Short Take-off and Landing (E-STOL) Author: David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com , Linkedin Abstract My E-STOL comprises a aerodynamic resistance of quite small area (SAR), being rigid and turnable, and a water jet device (WJD), comprising high pressure water jets in corners of quadrangular frame. The SAR can be very quickly erected or downed to turn it into additional wing-kite for short gliding in the sky. The WJD provides stabilization below stall speed and serves as start support, while landing or take-off. It is very attractive for Navy aviation, because allows high cruise speed, extremely short runway, and better reliability vs. helicopter, and we can repeat approach, if taking a portion of ambient sea water, in flight by simple pails.     The water is thrust out through the jets by gases at high pressure after ignition of “liquid vigorous combustible” (LVC), e.g. stoichiometric composition of amm

Breakthrough new fuel is better than oil

Breakthrough new fuel is better than oil David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com Abstract Lithium hydride being reformed by water vapor in hydrogen then by fuel cell can create 5.25 kWh electricity/ kg. LiH, vs. 3.75 kWh per kg gasoline, while that LiH needs for its recycling 10.3 kWh renewable electricity , so system energy efficiency is 50% without any harmful exhaust. For the oil, analogous technology or by burning the both are followed by the oil recycling, they are 25% energy efficient with a lot of harmful exhaust.. Really For Lithium hydride, it was evaluated by me in the article : “Breakthrough kind of electric vehicle” in https://judbarovski.blogspot.com /2022/11 , posted at Nov. 05, 2022 For the oil, it is recycled from atmospheric CO2 and hydrogen produced by the water splitting.
