you don't know the field, the magic discovers the world around you subscribe to d w documentary on youtube. me. ah, ah, ah. is it all just a lot of hot air? investors have been snapping up hydrogen related stocks as if the gas were in short supply. it's the most abundant elements in the universe like now sun. but on earth

it's mostly extracted from fossil fuels and meeting carbon dioxide in the process. what's got trade is excited, and companies promises of clean hydrogen. electrolysis splits water into hydrogen and oxygen doing it cheaply, could be the holy grail of green energy. so could hydrogen become the fuel of the future? that's what we're looking at today on made. i been for the woman. share prices of companies in the industry have soared more than 500 percent in the past year. there are several reasons. 0 emission vehicles are all the rage. many countries are going carbon free in the next few decades. us president joe biden has thrown his wife behind the sector and the european union plans to scale up renewable hydrogen projects in polluting industries like chemicals and steel. but a lot of the focus so far has been on cars. the question is, will hydrogen powered cars overtake their electric cousin?

the. what's the deal? when we all supposed to be driving plug in electric cars, their own offer a pulse of co sharing plums in many cities. but now hydrogen vehicles of the things over the past 2 decades, several hydrogen models has been unveiled, though most of them use hydrogen and combustion engines. but was about hydrogen cars with electric motors like this one. wheels the head of the german hydrogen and fuel cell association about the advantage over plug in cost. about my plug in electric cars have a distance problem with ranges are growing, but come with up to 4 hours. we charging time who wants to set off on vacation? and have to take a 4 hour break every 250 kilometers. it's not an option. it's not, this is work is not soon. houses this h to power call work in both the kind of factory known as a fuel cell surgeon from the air and hydrogen from the tank come together,

react in the fuel cell, producing electricity. how is the cars, electric engine? what comes out of the tail pipe? water, unlike combustion engine, no exhaust fuel or carbon dioxide produced but only a few call may cause manufacture them, such as high on di. i'm sorry. i'm the technology remains expensive. a car like this, toyota, mariah cost 79000 years at the moment in the future, a new model is expected to sell for about 64000 cherise. why is it still so costly? thought so it isn't the way the vehicles are sufficiently well developed to be sold at ordinary car prices if they were mass produced going. but at the moment there's a lack of demand off. perhaps also there's not enough state intervention to ensure that enough vehicles are accepted. so click on the missing not so

well and good, but so far the hydrogen itself is mainly produced using fossil fuels. not exactly climate friendly. the found with the institute of systems and innovation research was calculated how much h t would be needed in germany to fully exploit hydrogen technology. and it's a lot, i think, 2018 a total of $560.00 terror. what hours of electric power was used in germany, even if electricity consumption stayed the same and 2050 as much as double time will be required to produce all the hydrogen needed for fuel cells. i'm for making synthetic fuels. to generate told us extra power, germany would have to expand wind and solar on a must have scale to produce both enough hydrogen for transportation and enough electricity for other uses. that would mean about that stuff. and if we want to or are allowed to use hydrogen for mobility done,

then this hydrogen can only be generated with renewable energy. so i thought we would have to build up trade relations with countries with huge amounts of base and sunshine and wind available. and that are willing to become our energy providers of the future when the sustainable energy plants would have to be built there. and so hydrogen could be produced and transported via pipelines or ships to germany or trans transport. okay, so the message is renewable energy would have to be expanded massively to produce enough hydrogen. but not only is that still a lack of hydrogen, but also if the necessary infrastructure such as filling stations in the capital berlin, that recurrently just 5 hydrogen filling stations. and a total of $93.00 germany ah, filling up takes just 3 minutes and then the car can travel, 500 kilometer kilometer all driving 100 kilometers

costs, just as much as with a diesel engine. so it's not more expensive for the customer with the industry has agreed to build a significant number of filling station. i'm up to $400.00 of them without looking at exactly how many cars there actually are ships. i'm the support from policymakers, not just to expand renewable entities, but also hydrogen production. in december, the german government launched a new pilot project in chile, where siemens plans to produce synthetic fuel using hydrogen experts think the h to technology in the form of fuel cells is also being taken more seriously. the in years ago, it was more like an engineer's dream. it's such a cool and clever technology, and we now have clear binding climate targets in the greenville gave us more ambitious target. we realize that these are not attainable with conventional combustion engine. we simply need different technology often under the pin number. on the other hand, the global market for hydrogen and synthetic fuels made from his growing scientists,

found water institute calculate that the market volume will reach up to a 102000000000. you're right. why 2030 and as much as 680000000000. you're raised by 2050. good prospects that in the hydrogen technology. in 10 years, many more of these vehicles looks to be cruising through the country. but it's still not a given hydrogen as a fuel because sounds great. the gas could one day play a major role in slowing global warming. still, it's not always the best technology. the width is the one that clinches market share and rides the network effect. some analysts, the warning of a bubble. the frenzy and hydrogen related stocks has companies trading at extreme prices based on expectations that their revenue will surge in the future. despite worries about possible headwinds for the fact that there was a similar burst of enthusiasm about 20 years ago. that prove short lived. and

another thing is abundant energy source has to get a lot greener 1st to make an impact on the planet. if it really hits the streets that is or takes its place in other industries, hydrogen is considered an important energy source of the future. is supposed to make of a key part of your transition to sustainable sources of power. that does cause a russia dam is investing in h 2 in a big way it's planning to build a hydrogen network covering the entire port aiming to become a hub for producing, importing and transporting the gas to other european countries. but is hydrogen truly green hydrogen itself? is actually color this, but it's called gray, blue, or indeed green, depending on the manufacturing process used to produce it. today most hydrogen is gray. it's made from fossil fuels like natural gas and coal,

and produces high levels of c o. 2 emissions blue hydrogen is also great in the sense that it too is gained from fossil fuels. but the climate damaging c o 2 is captured and stored in empty gas feels under the sea. for example. though the carbon footprint is significantly lower in the green manufacturing process, hydrogen is derived from water. this is the only form of h to production that can be described as sustainable these days. oh hi. genes. same because it's always the molecule h 2, but the different manufacturing processes determine how high the greenhouse gas emissions are and how clean the hydrogen is. this is green, hydrogen is produced by splitting water into oxygen and hydrogen with electricity.

but that electricity doesn't always come from 0 emission sources. so even green hydrogen is only sustainable if the power used to make it comes from renewable, such as wind, solar power in only then is it produced without emitting any carbon dioxide or not. if it's to be green and sustainable, the hydrogen has to be produced using renewable if you have it. but what if a country doesn't have enough renewable electricity to cover the need for green hydrogen production? germany, for example, has insufficient wind solar power. so by 2050, the country will have to import 45000000 tons of hydrogen. the risk the is that transporting it over long distances by ship or pipeline could cause further environmental damage. i'm going to tell you home. one point of course, is certification. we need

a global certification system to really prove that this hydrogen has been produced from green electricity, water as well. right now we don't have that because there's no agreement on it yet . another hurdle for a quick transition to truly green hydrogen is the cost then the moment in that in given building, if you compare renewable green or even hydrogen with fossil fuels under the current regulatory framework, then it's a very expensive option and stuff and enough before the toilet value onto but as more electricity is produced from renewable sources, green, hydrogen should become less expensive. full cause, predict the cost will more than hum, buy 2030. but so far, the production of green hydrogen is not widespread in the european union. experts predict that the blue option where the seo to emitter during production is

stored will remain a peaceful of hydrogen for years to come. well, germany is keen on expanding its capacity for hydrogen production. the aim is to produce the gas on an industrial scale with 0 emissions. this green hydrogen would be use not only for fuels but also for heating and generating electricity still produces like to some cope. and i'd get are investing billions of euro's to make production, climate neutral with the help of hydrogen power. even oil giants are getting in on the act b, p developing a renewable hydrogen project at its refinery. here in germany to replace a big chunk of its fossil based hydrogen consumption. the road to greener energy leads to am slammed. the northern german district hopes to play a leading role in the countries transition to renewable energy.

jim horseman coordinates the development of hydrogen production infrastructure in the region. this wind together with offshore wind turbines to generate the power that will be used to produce hydrogen in a carbon neutral process of fuel compete behind using hydrogen is to achieve c o 2 neutrality that units transitioning from fossil fuels, using renewable energy, replacing all that natural gas and petroleum by alternatives, and that has to be wind energy, your solar energy $1.00 and $1.00 m. slend is in good shape economically with modern industrial and commercial enterprises. well funded with texas, the region can afford to invest heavily in the energy transition while melting national b. p runs a huge refinery and m land refineries like this one are among the biggest

industrial consumers of hydrogen. several tons per hour needed to remove sulfur from the gasoline and diesel produced here. but what's being used is so called gray hydrogen derived from natural gas in a process which emits large amounts of climate damaging seo to the plant is being converted so that in future it can produce carbon neutral, green hydrogen, livingston. and i don't forget that there are large furnaces in plants like you're going to use large amounts of energy are needed here. it's $120.00 megawatts, $120.00 reactor to build the capital is highly energy intensive. produce and lots of c o. 2 new pledge are pure electrolysis unit needs much less energy with almost no c o 2. but it's very expensive without state subsidies, it would be difficult to realize the plans defense. then you subsidize green

hydrogen costs more than great hydrogen. so there's no economic incentive for it. why would a market driven company use green hydrogen, but it just costs some money and their customers won't pay for it. and so subsidies are central guide and both the german government and the you agreed that they will be in the building in the since in the yard. making industrial facilities more eco friendly cost. a lot of money at this power plant green hydrogen, could soon replace natural gas and german energy multinational w e plans to build one of the world's biggest hydrogen production plants on this field. green hydrogen is opening up entirely new business opportunities of smoke does help to that we already have low cavern storage facilities in our portfolio in which we can temporarily store the large amounts of hydrogen, calm and gentle.
