Animation movie about the process inside HyGear's Hydrogen Generation System (HGS). HyGear's HGS uses the process of Steam Methane Reforming to generate hydrogen on a small-scale. HyGear is a clean technology company with expertise in small-scale Gas Generation, Gas Purification and Gas Recovery Systems. HyGear's lead product is the Hydrogen Generation System (HGS) that generates hydrogen on-site by steam reforming of natural gas. The system reduces logistics, costs and emissions significantly. Second product line is a range of Gas Purification Systems (GPS) to recover waste gas streams or upgrade the purity of hydrogen, nitrogen, oxygen or methane into purities up to 9.0. The GPS can be installed on-site as sole system or extension of the Gas Generation System, and can be adjusted to customer specific needs. Other focus areas are Energy- and Heat Recovery Systems, Fuel Cell systems, Gas to Liquid systems and combined Heat & Power systems to generate electricity and heat at remote locations. Besides these standardized products, HyGear offers a broad range of gas processing technologies such as (V)PSA, reforming, gas separation and purification, desulfurization and methanation. With these systems and technologies, we are able to offer customer specific solutions that contribute to energy efficiency, process intensification, supply chain efficiency, emission reduction and the utilization of renewable energy sources. Major shareholders are Abengoa Hidrogeno S.A., one of the largest bio-ethanol producers (www.abengoa.es) and PPM Oost NV, a Dutch investment company (www.ppmoost.nl).
Pressure to reduce carbon emissions is putting the future of fossil fuel giants in jeopardy. Their survival plans involve carbon storage and floating wind farms. Meanwhile, one small German village is showing how large companies aren't always essential. Click here to subscribe to The Economist on YouTube: http://econ.trib.al/rWl91R7 Over 80% of the world's energy needs are provided by coal, oil and gas. Although technologies to extract fossil fuels may have changed over the decades, the core products themselves have never been challenged. Until now. Pressure to reduce carbon emissions is putting the future of fossil fuel giants in jeopardy. Encouraging the growth of alternative methods to generate and distribute power. In just eight years, the value of the world's biggest power companies has halved. Leaving industry giants scrambling to redefine their role in this new energy world. Across the world, old industries are facing disruption on an unprecedented scale. The pressure to adapt has never been greater. Known as the Paris Accord, 195 countries agreed to a legally binding climate deal to reduce carbon emissions. This 5 trillion dollar industry may be facing a seismic shift but that doesn't mean it's ready to ditch the dirty fossil fuels that made it rich. Instead, many companies are banking on new methods to clean up an old process. Norwegian oil and gas giant, Statoil, struck it rich in the North Sea in the late 1960s. Over four decades later, at its Sleipner gas rig, the company is attempting to make fossil fuel production cleaner. Statoil's business still relies on the harmful burning of fossil fuels by its customers but at least the company is trying to reduce its own carbon footprint. It's transformed some of its offshore rigs with technology that enables engineers to separate the carbon dioxide and pump it underground. Statoil's Sleipner gas rig is the world's first offshore carbon capture storage plant. Each year, Statoil stores 1 million tonnes of CO2 making extraction less carbon intensive. They believe that prioritising gas over more harmful fossil fuels will further reduce global warming and keep them relevant for decades to come. Wind and solar are cleaner but depend on subsidies. To take on the consistency of fossil fuels they face a huge challenge - The unpredictable weather. In Bavaria, a tiny village has used those subsidies to take up the challenge. This community believes it's found a way to produce a steady energy supply just from renewable sources, raising the real prospect of a future free from fossil fuels. Norbert and Kristina Bechteler's family farm has been providing the local community with dairy products for over 200 years but they now have a new income from solar energy. Producing your own energy with solar panels isn't revolutionary but in this village, they're combining solar with other renewables in an attempt to achieve the Holy Grail of a steady energy supply. And they're prepared to use anything to do it. The Deputy Mayor has helped drive the village's pioneering efforts to make renewable energy a realistic option. There's one renewable that never disappears as it can be sourced from the decay of virtually any organic matter and it's called biogas. Of the four biogas plants in the village, Farmer Einsiedler runs the largest. Combining these different sources has been so successful the village now generates five times more energy than it needs. But that is just part of the challenge of turning renewables into a credible energy supply. The Disrupters is an original series exploring how major industries – from music and cars to hospitality – are currently being disrupted by the latest wave of digital innovation. As well as enjoying privileged access into the world biggest tech start ups we show how industry giants respond when faced with such tech-driven innovation - do they adapt - or die?

Jether Blaise back with a vengeance, covering the impact the abundance of natural gas has been having on the chemical industry, and the innovations in process technologies that it has spawned. I look at the contrast between processing petroleum as a chemical feedstock vs. processing natural gas as such. Because of the steep energy costs associated with steam reforming of natural gas, and the Fischer Tropsch process, new approaches have been sought out by chemical engineers to lower the costs of producing syngas, or sidestepping that route altogether.
Also, we take a look at a promising technology for reducing the water footprint of hydraulic fracturing and horizontal drilling, and finish up with a look at China's largest propane dehydrogenation facility.
