Liquid hydrogen “batteries” for storing renewable energy, LOHCNESS


​Finnish needs and research highlights on hydrogen - focus on liquid LOHC “batteries” and hydrogen legislation

Seminar on 7th November 2018, Espoo

None of the today’s energy storages is feasible to serve all needs in the revolution from fossil to carbon-free renewable energy. Hydrogen is a flexible energy carrier, however, its storage, transport and use as compressed or liquid form is challenging. Liquid organic hydrogen carriers (LOHCs) resemble liquid hydrogen "batteries" as they can be reversibly hydrogenated and dehydrogenated using catalysts. Furthermore, pathway to hydrogen economy is feasible only when in line with legislation.

Hydrogen seminar on 7th November 2018 discussed energy system needs in the transition to renewable energy for power plants, transport, residential and chemical sectors. The LOHC concept was presented in technical and economical terms. Legislation and regulation related to hydrogen were introduced with country-specific examples using database and tools available at National research projects related to hydrogen were presented as posters. Seminar was organised by

  • The LOHCNESS project ( evaluates feasibility and performance of LOHC solutions by identifying the business possibilities and best uses around the concept. Partners are VTT Technical Research Centre of Finland Ltd., University of Helsinki, Fortum, St1 Renewable Energy Oy, Oy Woikoski Ab, Leppäkosken Sähkö Oy and Aino Energia Oy. Project belongs to Smart Energy program of Business Finland.
  • The EU project HyLAW ( has identified and analysed the legislation and regulation related to hydrogen. HyLAW has brought together 23 partners providing public authorities country-specific benchmarks and recommendations on how to remove the legal barriers to the deployment of fuel cell and hydrogen applications. The HyLAW project has received funding from the Fuel Cells and Hydrogen 2 Joint Undertaking under grant agreement No 737977. The HyLAW project is coordinated by Hydrogen Europe.


Opening: Kalle Kantola, Vice President, Research, VTT Technical Research Centre of Finland Ltd.
