In China, most fuel cells operated cars and buses are built and operated. State funding for battery electric vehicles was discontinued there in 2019 because it is considered unlikely to create a charging infrastructure for this type of mobility across the country. A new production facility for the fuel cell electric Toyota “Mirai” is being built in Japan to reduce the waiting time for the purchase of such a car to half a year in the foreseeable future. The purchase of fuel cell house heating systems has not been subsidized for about two years because the prices of such heaters have adjusted to conventional heaters due to the sales figures. The South Korean Hyundai Group has been building fuel cell SUVs in series production as the world's first manufacturer since 2013 and has started delivering 1,600 fuel cell trucks to Switzerland by 2025.
In Germany, federal ministries and the Federal Council are brooding over the draft of a national hydrogen strategy, whereby the northern German states, including Mecklenburg-Western Pomerania, had already prepared a previous document relating to their territory last year. We see that progress is being made towards green hydrogen, even if in principle only intentions have so far been explained. Regulations, which should make it possible to operate the production and use of green hydrogen as a business case, are to a certain extent in the air (e.g. "CO2 tax"). Green hydrogen is now generally regarded as essential for the use of renewable energy. It is required as a storage medium for green electricity that is not produced in accordance with consumption. It will enable it to be leveled out and thus make conventionally fired (balancing power) power plants unnecessary and end the unspeakable shutdown practice for wind and photovoltaic systems. At the same time, materialized electricity would be available as a fuel, as well as for replacing fossil-based hydrogen to produce all kinds of coal-hydrogen materials. Used directly or mixed with natural gas, green hydrogen also begins to decarbonize the heating market. Finally, the focus for the use of the clean energy source is on productions that are fundamental to the economy, such as steel production.
All this means that new perspectives for the relationship between people and nature have opened, new dimensions for finally sustainability in technology and production. It has long since become clear that we few Germans will only have a marginal impact on climate change. However, we can give an example and we must strive for the chance to live from the export of the necessary machinery (electrolysers, fuel cells, storage technology). All of this has also made it clear that much more green energy will be used in Germany than can be produced in the country.
Contributions from the REGWA symposium
These problems and correlations have been and have been presented and discussed at the Stralsund Energy Symposium for almost thirty years. The magazine “HZwei” recognizes in its January edition “Hydrogen history was written in Stralsund.” And does not only mean the scientific conference. But it was precisely on this that the Austrian / Argentine thought leader in the wind energy industry, Erico Spinadel, announced in 1995 that wind and water-rich Patagonia would become the Kuwait of the twenty-first century. This prediction, which includes green hydrogen, differs from the idea of Ludwig Bölkow, who spoke more than forty years ago of photovoltaic power generation for Europe in North Africa and thought of a line system. Negotiations are already underway between Argentina and Japan on Patagonia.
Also at the Stralsund Energy Symposium in 2004, Sandlass / Wenske / Machens described the idea of using wind power to generate electricity off Germany's coasts and operating electrolysis directly at the wind farms, because hydrogen transport would be cheaper than submarine cables. This idea has now been taken up for a project in Warnemünde. (A reprint of the relevant publication is planned for this year's conference volume of the symposium.)
Another idea is closely connected to the Stralsund conference: In 2007 Crotogino and Hamelmann showed impressively that the hydrogen can only stabilize a network operated with volatile electricity if conservative power plants for balancing power are not to be used. All other clean storage options are not sufficient in terms of their storage capacity. With this work, the discussion was opened that green hydrogen is suitable for coupling the sectors for the entire energy industry and can thus enable a successful energy transition.
What will the 27th symposium bring?
The North Vorpommern-Rügen region has been selected by the NOW as one of nine regions to be supported and promoted within the HyStart program to develop project proposals for the introduction of green hydrogen for the territory. Perhaps in this connection we could orientate ourselves on the “Wind in the Tank” project for the west coast of Schleswig-Holstein, which was presented by GPJoule at the previous REGWA conference. Because at least one thing is interesting about this project: as long as innovation is inhibited due to lagging regulation, pioneering projects can be guided past outdated rules. Perhaps this could also be linked to earlier, generously funded projects: after all, there has been an H2 gas station with an electrolyzer in the sewage treatment plant since 2003 against the background of the use of regenerative energy, but meanwhile only oxygen is used to operate the sewage treatment plant. After all, the "Pommernbus" with fuel cell, handed over in 2006, a product of a Stralsund company, is still in a condition that should allow it to be "revamped" and put into operation again.
At least at these points there is a need for discussion and the need for project partners to come together.
Lectures are planned on the following main topics:
Will the link with green hydrogen help the wind industry in our country again after it has gotten into trouble due to bad political decisions? Will the German automotive industry turn to fuel cells unconditionally and thus gain momentum? Is the energy transition using green hydrogen expanding to the general transition to sustainability in products and productions?
The complete catalog of topics for the desired contributions to the 27th Stralsund Energy Symposium can be found under Information about the call.
The organizers, Stralsund University of Applied Sciences, and the Hydrogen Technology Initiative MV e.V. are looking forward to a lively participation, interesting lectures, and exciting discussions. We meet in a friendly atmosphere and will exchange experiences. As always. Or not according to the pattern as in previous years. While this call was written at the beginning of March this year, one topic has come to the fore: Corona. In line with developments, we will adapt the design and course of the conference to the conditions in November. It will probably be a face-to-face event and contributions to the planning symposium that can be tracked online. After all, the organizers were able to train this method in the teaching of Stralsund University during the spring semester 2020. We will inform you of this in good time on the conference website.
Nevertheless, the pandemic is a remarkable example of the content and concerns of the REGWA conference: Even the United States admits that the WHO officially warned at the beginning of 2020 of the possibility of a corona outbreak using the usual information channels. However, hardly any of the responsible politicians perceived or wanted to admit it or could not understand it. The world has slipped in and will face the consequences for many years to come. We had that before! In the mid-1970s, a group of responsible scientists, the Club of Rome, held up the mirror in a highly remarkable memoir entitled "Limits to Growth". It was warned of the already clearly noticeable consequences of an ever expanding and by no means sustainably operated production of industry and agriculture, of a more than linearly increasing world population and the increasingly excessive demands on the level of prosperity in the developed countries. These findings have led to the successful discussion about the sustainability of human activities, and measures have been taken and changes have been made, particularly in Europe. But who could say that this would be enough? The problems of acceptance and implementation of the decision of the Paris climate conference alone pose a dilemma. And the ice cap at the North Pole is melting away… The measurable increase in the mean temperature of the atmosphere, the rising sea level and the rising water temperature in the oceans are already pointing in the direction of Droughts and floods, drinking water problems and changes in flora and fauna, and thus also the difficult creation of food. How will we deal with migrations caused by this? Do we also slide into something here and only ask afterwards how it got there?
This is exactly where the organizers see responsibility for such conferences as REGWA. Just as the university releases graduates who are involved in green projects year after year, the scientific event is responsible for repeatedly drawing up ways in which sustainability in production can finally be achieved. We will all have to change gear.
