Recently in Kyiv there was a meeting on hydrogen energy. It took place June 6th in National University of Kyiv in the frame of the International conference in chemistry Kyiv-Toulouse 2017. The conference was created in 2001 and now it became an important event, uniting hundreds of participants from tens of countries.
This year for the first time a specific session was organized, which is dedicated to hydrogen energy. This field of clean energy technologies is developing very rapidly and requires constant attention from chemists to improve existing materials and processes and create new ones. That is why the chemical conference was the best place to meet researchers, especially because today Ukrainian hydrogen technology specialists do not have their own specialized conference.
Ukrainian scientists presented their results in the format of seven oral and ten poster presentations in English, which were listened to and watched by dozens of visitors. The list of all presentations is published on the conference website.
Taking into account large number of interested researchers, it was decided to make a special issue of the French-Ukrainian Journal of Chemistry dedicated to hydrogen energy.
At the end of the presentations, all the attendees joined a round table discussion on the perspectives for the development of hydrogen technologies in Ukraine. The main obstacles to progress in this direction were named the lack of funding, recent reduction of state-targeted science programs and the insufficient level of self-organization and communication between players of the hydrogen sphere. It was proposed to join efforts to coordinate actions to renew targeted programs, as well as to distribute information on the usefulness of hydrogen technologies and the contribution of Ukrainian researchers to progress in this field.
Carbon honeycomb is a new carbon structure, which the researchers describe as three-dimensional graphene. It could store large amounts of hydrogen gas, what could benefit hydrogen economy.
Carbon can form diamond, nanotubes, or the nanoscale spheres called fullerenes, as well as several other structures. Now a team of Nina V. Krainyukova and Evgeniy N. Zubarev of Ukraine’s National Academy of Sciences and National Technical University, both in Kharkiv, Ukraine, has produced what they call carbon honeycomb, a structure that appears to have a huge gas-storage capacity. By slightly altering a common fabrication method, the researchers created what appears to be a 3D honeycomb built from the carbon sheets known as graphene.
Young engineer from the G. V. Kurdyumov Institute for Metal Physics (IMP) of the National Academy of Sciences of Ukraine, Ph.D. Vladimir Dehtyarenko is working on development of new materials for hydrogen storage. His invention was awarded with the first prize at the competition of scientific and technical developments of young scientists within the international event "Science - Society - Personality".
Building of the Institute for Metal Physics
Scientist is working on research of intermetallic compounds (chemical compounds between metals) in order to find a material capable of easily absorb a large amount of hydrogen gas, store it for some time and to release it easily when needed. Invention of such material will improve the ratio of the weight of hydrogen stored to the total weight of the system (ie, make these systems lighter) and increase the safety of hydrogen tanks. Vladimir Dehtyarenko and his team found that one compound based on titanium, manganese, zirconium and vanadium has great potential for use in the hydrogen industry as solid material for hydrogen storage.

You are working on hydrogen in Ukraine? Let everybody know about your project!
Send us an article describing your ongoing research, your past results or your plans for the future, and we will publish it on our website. It will give you better visibility, which may lead to new contacts, new collaborations and for more financial possibilities.
There are a lot of interesting research projects take place in Ukraine (see, for example, this list
, in Ukrainian). One of main problems of Ukrainian science is a lack of communication: citizens and investors are ignorant about the progress in research and development programs. However, it is very important to communicate about your achievements and future plans. It may allow you to be found by investors, who are looking for your expertize and technology.
Let everybody know about your project! It will take only 30 minutes of your time to write a text, but it could bring you fame, new contacts and probably even investors.
