The electricity for the electric car can come from the socket - or from the fuel cell. On the road, however, this technology is an absolute rarity. A car rental company in Munich now wants to change that.

At a hydroelectric power plant operated by the energy company Energiedienst in Grenzach-Wylen, the production of green hydrogen has been running successfully for four months. The project produces 500 kilograms of hydrogen per day.
Hydrogen from hydropower: successful start for one of the largest power-to-gas plants in Germany to date. This is reported by the Centre for Solar Energy and Hydrogen Research Baden-Württemberg (ZSW). The megawatt plant has been in operation for four months in April 2020 and is functioning reliably. A research electrolyser connected to it is also running successfully. The ZSW is coordinating the project. The operator of the commercial plant is the energy supplier Energiedienst AG.
The power-to-gas plant with an electrical connected load of one megawatt produces renewable hydrogen using electricity from the Rhine hydroelectric power plant in Wyhlen. Since it is not necessary to use the public electricity grid, grid fees and the EEG surcharge do not apply. In addition, high full load hours can be achieved because the hydropower is available practically around the clock. This further improves the economic efficiency and enables extensive operating experience to be gained quickly.
He said the plant has been running regularly since early December 2019 and has had 1,850 hours of operation since then. Previously, it was in trial operation. The monitoring system set up by the ZSW, which measures all essential components and subsystems, functions perfectly. The plant operates fully automatically in 24-hour operation both at full load and in various partial load conditions.
The ZSW monitors operation with the help of remote data transmission to Stuttgart and automated data evaluation. The overall efficiency of electricity to high-purity hydrogen compressed to 300 bar is currently up to 66 percent in relation to the calorific value of the gas. In addition, the researchers are investigating ageing effects and deriving potential improvements from the data.
So far, the plant has filled 62 trailers with hydrogen suitable for fuel cells. Each of these transportable containers holds around 300 kilograms. The plant can produce up to 500 kilograms of hydrogen per day. This is enough for an average daily mileage of more than 1,000 fuel cell cars.
The research project docked to the commercial plant is also progressing positively. In a research plant, the scientists are testing improved electrolysis blocks with a maximum output of 300 kilowatts in parallel operation with the commercial plant. They should further reduce the price of hydrogen. But companies could also test and optimize components there.
Last year, the ZSW and its research partners already achieved an initial success during the test operation of the plant: with new electrode coatings, the researchers achieved 20 percent more power density compared to the electrolysis blocks of the industrial plant section. This means that less volume and material are required for the same output.
Since the investment costs are also based on the construction volume and the electrolysis units account for the largest share of costs in the conversion of renewable electricity at around 40 percent, progress in this area is automatically reflected in the price of hydrogen. For manufacturers of electrolysis plants, development is therefore an important factor for further cost reduction. The long-term goal of the ZSW researchers and Energiedienst engineers is to roughly halve the current production costs of electricity-based hydrogen.
The state of Baden-Württemberg supports the Lighthouse project with a total of 4.5 million euros. In 2019, a project based on this was selected by the Federal Ministry of Economics and Technology as one of the winners of the first round of the "Reallabore der Energiewende" ideas competition. A total of twelve partners are on board for this major project.

Question: The energy transition entered a new phase with the EEG reform in summer 2014. How do you assess the current situation?
Nina Scheer: The question of when it entered a new phase cannot always be precisely identified. In any case, it was outlined in the coalition agreement and was formalised in law with the EEG 2014. Now, for the first time, there are maximum limits for the expansion of renewable energy in the electricity sector. This is a fundamental change of course.
The idea was to create expansion corridors for each individual technology, i.e. caps and reins to regulate expansion. This view assumes that everything can be regulated. However, it disregards the question of what conditions are necessary for companies in the renewables sector and everything that surrounds it to gain a foothold in the long term. The companies must be able to generate profits in a foreseeable and long-term manner. There are now question marks over the future. Incidentally, this also applies to the switch to tenders. This is a second turning point, which is also not helpful for the energy transition.

URBAN MINING - The city as an eternal source of raw materials

While the mountains of waste in our cities are growing, raw materials are becoming increasingly scarce and expensive worldwide. For decades, mineral resources have been shipped to the industrial nations and used in high-rise buildings, mobile phones and cars, for example. Today, metropolises are gigantic raw material mines. Researchers and companies are now starting to mine.

The BMWi and the BMBF have responded to the Berlin Energy Days 2016 (11-13 April) presented the new interdepartmental funding announcement "Solar Building & Energy Efficient City". Its aim is to network the actors in this field and create synergies. To this end, the Federal Government is providing 150 million euros within the 6th Energy Research Programme. The focus is on cross-technology research projects and interdisciplinary cooperation. The aim is to build and modernise energy-efficient buildings and urban districts together with energy-optimised infrastructure. It therefore also exclusively supports cooperation projects. Industry, small and medium-sized enterprises as well as universities and research institutions can submit their proposals for research and demonstration projects. The funding initiative includes application-oriented research, development and demonstration of energy-optimised buildings (Module I "Solar Building"). On the other hand, the focus is on so-called lighthouse projects in the neighbourhood (Module II "Energy-efficient city"). The concepts developed in this way should be easily transferable to other projects and implement model supply strategies based on renewable energies.
At the same time, the BMWi is launching another funding initiative: "EnEff.Gebäude.2050". Here, application-oriented model projects on the topic of solar building are particularly in demand, which aim to transfer innovative technologies and concepts for broad application. They are being supported with a total of 35 million euros. The aim is to motivate the many players in construction, planning and architecture to take action and overcome obstacles to the realisation of particularly energy-efficient buildings.
