There is a lot going on in the energy sector at the moment. As a result of numerous activities and events – be it diesel scandals or CO2 pricing, driving bans or Fridays-for-Future demonstrations, flight shame or real laboratories – more and more players are committing themselves to more sustainability as well as to hydrogen as an energy storage.
The energy system of the future faces numerous challenges with its increasing decarbonisation, the further expansion of renewable energies and the coupling of the electricity, heat, transport and industrial sectors.
Iceland was quick to recognise the opportunities offered by hydrogen and fuel cells for the transport sector – but has unfortunately made little of them to date. At the end of the last millennium, the Nordic island was regarded as a pioneer in the field of hydrogen, because it considered the vision of a sustainable hydrogen economy to be quite feasible.
The member companies of the German Petroleum Industry Association (MWV) welcome the Paris Climate Protection Agreement and the associated targets to reduce greenhouse gas emissions in all sectors. The petroleum industry can make a significant contribution to achieving the targets with renewable fuels.
Green hydrogen, preferably produced by electrolysis, links the energy, industry and mobility sectors and is an important tool to enable the integration of renewable energies. Proton exchange membrane electrolysis (PEMEL) is considered the most promising technology due to its power density and dynamics.
Synthetic gases will play an important role in the full supply of renewable energies for Germany’s energy requirements. The meta-analysis of  shows that, according to several studies, an electrolysis capacity of more than 100 GW is required in the future energy system in Germany. If such an electrolysis capacity is to be installed in the course of the next few decades, it will be necessary to ramp up the market in good time so that market-driven, reliable and inexpensive plants can be made available.
When it comes to the subject of “infrastructure of electric vehicles”, there are many different opinions regarding costs, the possibility of integrating the infrastructure into the power grids and the efficiency of energy supply. Depending on one’s point of view, the infrastructure for battery cars is sometimes better than that for fuel cell cars.
Fuel cell technology offers an immense opportunity for future emission-free mobility. One of the biggest challenges for their breakthrough, however, is the currently still high costs compared to the gasoline or diesel drives established on the market.
California continues to move the needle in adopting more and more ambitious climate, energy and transportation goals, to improve air quality and reduce health impacts from emissions, and to develop a strong clean energy economy in the state that creates sustainable jobs.
Electric mobility represents an important contribution to climate protection and the use of renewable energies in the transport sector. VDE/ETG, VDI-FVT and VDI-GEU have therefore attempted to present the current state of development of fuel cell passenger cars (FCEV) and battery electric passenger cars (BEV) within the framework of an interdisciplinary working group made up of universities, research institutes and industry.
