Solid air hydrogen liquefaction, the missing link of the hydrogen economy
May 3, 2023
A group of researchers from various countries proposed an interesting solution to reduce the power consumption for hydrogen liquefaction.
Even not mentioned among the references, this solution has an ancestor proposed by one of the EnTraT partners. In 1993 at the 1st Conference on New Energy Systems and Conversions, in Yokohama (Japan), Giuseppe Spazzafumo presented the research entitled "Hydrogen energy storage: a specific plant for hydrogen liquefaction".
A new project from ZeroAvia and Alaska Airlines
May 2, 2023
Alaska Airlines has made a Bombardier Q400 (Dash 8-400)) available to ZeroAvia for conversion to hydrogen electric propulsion. The aircraft will be equipped with proton exchange membrane fuel cells powered by hydrogen stored as a cryogenic liquid and a 1.8 MW propulsion system, i.e. two "HyperCore" engine modules, high-power permanent magnetic flux radial machines (900 kW) and high speed (20,000 rpm).
A 2 kW photo-electrosysis system from EPFL
April 18, 2023
Researchers at the École Polytechnique Fédérale de Lausanne (EPFL) have built a photo-electrochemical system for hydrogen production that uses concentrated sunlight to directly split water into hydrogen and oxygen. Although the technology had already been extensively tested by various researchers, this is the first complete system, i.e. inclusive of all auxiliary components.
IEA rejects the classification of hydrogen by colours
April 14, 2023
The International Energy Agency considers the colour classification of hydrogen to be imprecise and confusing. For this reason, it has prepared a report entitled Towards hydrogen definitions based on their emissions intensity in which it proposes a certification based on an analytical scheme that considers the carbon intensity of the various hydrogen production processes.
Universal Hydrogen first test flight.
March 2, 2023
Universal Hydrogen conducted its first 15-minute test flight with a Dash-8 modified to operate on hydrogen fuel cells.
The Dash-8 is an aircraft capable of carrying 50 passengers over a short-haul distance. In the test configuration it was equipped with two 15 kg hydrogen tanks, an 800 kW fuel cell stack and an electric motor under one wing. As already happened for the recent ZeroAvia test flight, also in this case the propulsion was hybrid, with a Pratt and Whitney turboprop engine under the other wing.
Renewable hydrogen for EU
February 13, 2023
Today the Commission adopted two Delegated Acts which, within a period of 2 to 4 months, will be examined by the European Parliament and the Council and which establish what is defined as renewable hydrogen for the EU:
- the first defines when an energy vector can be considered RFNBO, i.e. renewable fuel of non-biological origin, ensuring that it is produced only from "additional" renewable electricity generated at the same time and in the same area as its own production;
- the second establishes the methodology for calculating the reduction in greenhouse gas emissions obtainable thanks to the use of RFNBOs and recycled carbon-based fuels, taking into account the entire life cycle. It also stipulates that the use of recycled carbon fuels must reduce greenhouse gas emissions by at least 70% compared to substituted fuels.
Nine countries lined up in favour of hydrogen from nuclear sources
February 6, 2023
This week, ministers from 8 European countries (Poland, the Czech Republic, Slovenia, Croatia, Slovakia, Romania, Hungary and Bulgaria) joined France in sending a letter to the European Commission urging it to equate hydrogen produced from green hydrogen nuclear energy, i.e. made from renewable electricity.
