power to gas is a process by which renewable energy is used to produce hydrogen or methane. as a cross - sectoral system solution, power to gas can make a substantial contribution towards integrating renewable energy into various energy consumption sectors. for example, the gases produced through power to gas can replace fossil fuel sources in industry, transport and heating. furthermore, power to gas enables the use of the natural gas network’s vast capacity for the storage of electricity which is generated from renewable energy sources but which cannot be integrated into the grid. power to gas has the potential to ensure long - term storage by using the natural gas network .
biogas and wastewater treatment plants could then supply power when needed. when there is excess power in the grid, it would make sense to save biogas or sewage gas and use the natural gas grid as intermittent storage. the entire system would become more responsive to actual demand if there was a power - to - gas plant set up next to the biogas or sewage gas one – similar to today’s installation of combined heat and power plants. when there is a power surplus, the power - to - gas plant would use the electricity to create hydrogen through electrolysis and bring the biogas or sewage gas up to natural gas quality as well as feed it into the gas network. this example also shows the growing link between the power and gas sector. for that to happen, additional investments will have to be made, according to schmack. “on the other hand, our method does away with the process of having to prepare the gas. ”
the german natural gas grid has immense storage capacities. this means that the production of synthetic methane from excess wind or solar power with the help of power - to - gas technology now presents real opportunities .

among dena’s recommendations is that power - to - gas plants stop imposing charges on the end user when buying electricity, because electricity is not consumed through power to gas, but converted, stored and made available for other uses, thereby serving as a means of energy storage. these changes would be possible under the new electricity market act. without charging the end user, the cost balance sheet of power - to - gas plants would improve significantly .
power to gas provides many advantages for local authorities: gas production stimulates the implementation of infrastructure and industrial equipment in the departments, thus leading to production of industrial facilities, which in turn create activities and jobs in the areas concerned .
the power - to - gas strategy platform supports the further development of the power - to - gas system solution. it is being implemented by dena, along with 37 partners from industry, research and associations. further information on the strategy platform and its partners is available at www. powertogas. info .
the peterhead ccs project is an important first step toward ensuring that the natural gas power plants being built today are part of the solution to climate change .
power to gas is a particularly promising system solution. the idea behind power to gas is to convert renewable electricity to hydrogen or methane, store it in the gas infrastructure and then use it in a variety of consumption areas. hydrogen and methane from renewable electricity can be used equally in mobility, industrial, heat supply and electricity generation applications. that makes power to gas a multi - system solution which supports the integration of renewable energy into the energy system and also contributes to reaching the ambitious goals of reducing emissions of greenhouse gases and the sustainability goals in all areas of consumption .

an ambitious plan to slash greenhouse - gas emissions must clear some high technical and economic hurdles .
the increased availability of natural gas is leading to its expanded use worldwide. substituting natural gas for coal as a fuel for generating electricity helps reduce the carbon emissions that contribute to climate change because burning natural gas emits only about half as much carbon as burning coal .
the current plant size is 200 kilowatts, which corresponds to a converted power of 100 kilowatts of methane gas. performance is planned to be increased step by step to 400 kw, a move which has already been approved by the grid operator. “we are very satisfied with how the process has developed so far, ” says schmack. the future would bring power - to - gas plants of between two and five megawatts, although plants with even more power would be quite rare .
because there is no storage solution, the units are shut down, or the electricity is lost to avoid saturating the networks. the technological innovation featured in the power to gas demonstration plant provides a solution for storing and using the surplus electricity, by transforming it into gas .
accurate information regarding the uncertainty of short - term forecast for aggregate wind power is a key to efficient and cost effective integration of wind farms into power systems. this paper presents a methodology for producing wind power forecast scenarios. using historical wind power time series data and the kernel density estimator (kde), probabilistic wind power forecast scenarios were generated according to a rolling process. the improvement achieved in the accuracy of forecasts through frequent updating of the forecasts taking into account the latest realized wind power was quantified. the forecast scenarios produced by the proposed method were used as inputs to a unit commitment and optimal dispatch model in order to investigate how the uncertainty in wind forecast affect the operation of power system and in particular gas - fired generators .
some large - volume fuel consumers such as electricity producers and iron, steel, and paper mills can switch between natural gas, coal, and petroleum, depending on the cost of each fuel. when the cost of the other fuels fall, demand for natural gas may decrease, which may reduce natural gas prices. when the cost of competing fuels rise relative to the cost of natural gas, switching from those fuels to natural gas may increase natural gas demand and prices. in 2016, more electricity was generated from natural gas than coal for the first time on record, and natural gas was the largest source of overall electricity generation .
of course most business do not buy power through a wholesale market, and almost everybody has to pay grid distribution charges. so the logical place to put these electrolysers is next to wind farms or solar parks which can use power at no direct cost. when these entities are expecting to get very low power prices they will swing over to making hydrogen instead .
several p2g systems are in operation across europe and canada, but the uci project is a smaller, proof - of - concept design, funded by local utility southern california gas co. and installed at the campus gas power plant .
the intermittent nature of renewable power generation has long been a potential barrier to a low - carbon future .
once p2g plants work out such issues, they could scale up, and synthetic gas could go directly into the network of pipelines and storage tanks currently used for natural gas. it could then be burned in power plants to produce electricity; by some estimates, this technology will be able to store up to 500, 000 gigawatt - hours of electricity, enough to power germany for more than six months .
the gas collection facility is a fenced area and includes a 2, 400 square foot building located at the entrance to the landfill. the gas flare stands 40 feet high .

by helping to supply ngv with a neutral carbon footprint, power to gas makes an efficient contribution to the energy transition. the green gas thus produced, which emits lower levels of co 2 and particulates than petrol or diesel fuel, also constitutes a viable alternative to fossil fuels for transport, with the effect of reducing air pollution levels .
what is the net impact of this transformation of electricity to natural gas? first, the surplus of electricity is reduced. second, the energy in the electricity is largely transferred to the energy in methane. this methane can be indefinitely kept in natural gas networks, which generally have a capacity for storage vastly greater than the batteries are ever likely to possess. although britain has relatively little gas storage, other countries often have months of capacity. they can make gas when electricity is abundant and then use that gas to generate power when the wind and sun are not available .
is landfill gas harmful to the environment? as landfill waste decomposes, a type of gas, called' landfill gas' (lfg), is produced and emitted into the atmosphere. landfill gas contains almost equal parts of methane and carbon dioxide. methane is about 25 times more harmful to the environment than carbon dioxide. the larger the landfill is, the more gas is produced. while emissions decline year after year after a landfill is no longer in use, they continue to emit gas into the atmosphere for as long as 100 years .
green gases and power - to - gas are key elements for a viable and sustainable energy mix of the future. this concludes a report released in february 2018 by the dutch consultancy trinomics .

“storage capacities of the natural gas network correspond to the pow - er produced from the wind and sun over several months, ” explains dimosthenis trimis, kit, coordinator of the helmeth eu project. “what we need are the technologies to change among energy carriers, if necessary. ” research into the connection of the power grid with the natural gas network is conducted under the heading of power to gas (ptg). ptg might be one element of a transformed energy system in germany .
hydrogen has long been produced through energy - intensive electrolysis (the other equally unsustainable method being to extract it from natural gas). however uk firm itm power has pioneered a new system of electrolysis which can connect to the grid and work instantaneously with surges in power supply that would otherwise be wasted, creating high - pressure hydrogen as a fuel or injecting it directly from the electricity to the gas grid .
we really need this to happen. first, it means we can happily heat buildings with low carbon electricity, even without the advantages of heat pumps. more important, it means that instead of using fossil natural gas for power and heat generation, we can use renewable natural gas instead, particularly when power is costly because of lack of wind and sun .
the central component of the process is the electrolyzer, which takes in water and uses excess clean electricity to power an electrochemical reaction that splits it into hydrogen and oxygen. the latter is released into the atmosphere, and the hydrogen is compressed and sent about 60 feet through a pencil - thin, stainless steel tube to an injection point in uci’s natural gas pipeline. the hydrogen is mixed with natural gas and burned in the gas turbine power plant to generate electricity and heat for the campus .
why not use the sun to create energy for the grid and use it to power evs and use the leftover hydrocarbons for aviation fuel .
this is one of the main arguments used by proponents of nuclear power, for example .
“it needs the right environment to make the conversion of power to methane gas an economically viable option, ” explains schmack. it will require excess power from renewable energies, which one could get free of charge under the best circumstances. “today, we are obligated to pay the eeg charge on the power used, whose feed - in would otherwise be restricted, ” explains schmack, and he adds: “this is unacceptable. ”
there are several options to reduce power (w) including optimizing solution temperature, cell dimensions, and solution conductivity .
the commercial use of power - to - gas technology is primarily being considered in europe, where it is being reviewed by the european gas research group, as well as the energy departments of several nations. in germany alone there are 18 different experimental programs being conducted. power - to - gas conversion is also being evaluated for commercial application in the united states by the southern california gas company, in conjunction with the u. s. department of energy' s national renewable energy laboratory and the national fuel cell research center at the university of california, irvine .
“we’ve shown you need not halt renewable power generation when demand is low. instead, the excess electricity can be used to make hydrogen that can be easily integrated into existing natural gas pipeline infrastructure. ”
germany is not the only country in which power - to - gas is currently trending. the markets in scandinavia and california are growing as well. schmack has already received several requests for project specifications .
that’s why it’s important to note the recent announcement in the united kingdom of the next step in building the first full - scale commercial natural gas power plant using carbon capture and storage (ccs) .
‘power to gas is a key technology for climate protection and the energy transition, ’ says andreas kuhlmann, dena’s chief executive. ‘everyone says how important it is to harness renewable energy in all sectors – not only in the electricity sector, but also in mobility, industry and in buildings. linking sectors is the key term and, for that, power to gas is a good solution that is available on an industrial scale. in our potentiality atlas we are offering political and economic decision makers an important basis for information. ultimately, to enable a quick and significant reduction in greenhouse gas emissions, market access to power to gas must be made easier. there are promising initiatives in many regions. however, in national legislation there are still some obstacles that need to be removed. ’
whether countries are replacing old coal power plants or meeting new energy needs, these new natural gas - fueled assets will be around for decades to come. while the difference in emissions between combusted coal and natural gas is significant, that reduction alone is not enough to avoid the most dangerous impacts of climate change .
at present, minnesota power operates 10 hydro plants, two biomass and coal plants, two wind farms, two coal plants, and one natural gas–fired plant. the company has already met or exceeded state standards for renewable power, along with energy conservation and carbon emissions, through a fleet transition of smaller coal units and its increasing use of wind and solar power .

the practice – known as blending – does however provide an opportunity for power - to - gasers like itm to make their electrolysers cheaper and more efficient .
some natural gas plants can produce electricity without steam. they use turbines very much like those on jet - aircraft. instead of burning jet - fuel and producing thrust, however, these units burn natural gas and power a generator. gas - turbine generators have been popular for many years because they can be started quickly in response to temporary demand surges for electricity. a newer twist is the
combined - cycle
plant which uses gas - turbines in this fashion, but then channels the hot exhaust gas to a boiler, which makes steam to turn another rotor. this substantially improves the overall efficiency of the generating plant .

it also has a significant and growing involvement in natural gas gathering and midstream businesses, and an increasing involvement in power transmission and has interests in close to 1, 000 megawatts of renewable and alternative energy generating capacity .
using seawater in the cathode compartment will reduce the resistance of the module and lower the power consumption .
in much the same way as the soda mixer, it is possible to mix hydrogen into the natural gas pipeline network. this is a way to absorb excess solar and wind energy: surplus renewable electricity is put into an electrolyzer to create hydrogen, which is temporarily stored in buffer tanks, and then injected into a natural gas pipeline’s flow of gas .
the collection process involves covering or
capping
a section of the landfill with clay, drilling vertical wells into the waste and connecting them with underground piping. vacuum compressors then capture the gas and pipe it to a blower / flare station, where it is either piped to the power generation facility or combusted in a flare. during the combustion process the methane is converted to carbon dioxide, a less harmful gas. while effective at reducing methane gas emissions, ending the process at this point makes no use of the heat energy that is produced during the conversion. after the gas is collected, it is piped to a power generation facility and combusted in two engine - generator sets to generate electricity .
during cold months, natural gas demand for heating by residential and commercial consumers generally increases overall natural gas demand and can put upward pressure on prices. if unexpected cold or severe weather occurs, the effect on prices intensifies because supply is often unable to react quickly to short - term increases in demand. the effect of weather on natural gas prices may be greater if the natural gas transportation (pipeline) system is already operating at full capacity. natural gas supplies in storage may help to cushion the impact of high demand during cold weather .
after the demonstration plant was now disassembled and reassembled at viessmann’s headquarters in allendorf, the hydrogen produced on - site by microbial methanation is fed through the available biogas plant into the natural gas grid. the required co2 is either taken from the gas processing plant or the raw biogas is used directly, including its inherent co2. in this case, the power - to - gas also prepares the raw biogas .
there are a many ways to produce electricity. electrons can flow between certain different materials providing a current, as in a common battery. while reliable and portable, chemical batteries run down quickly. to provide the large amounts of steady power demanded by modern societies, large power plants have been built. most power plants make electricity with a machine called a generator .
the use of existing biogas and wastewater treatment plants could lower the costs for power - to - gas installations, because both the transformers and the power as well as gas grid connections will already be in place. another advantage: the reaction only takes seconds and the produced methane is relatively pure. common processes wash out the co2 from biogas production. in the future, hydrogen will be added to the biogas or sewage gas, and the micro - organisms will get to work on converting the co2 in it into ch4. this results in a synthesized gas that can be fed into the grid and a methane content that is almost doubled from a good 50 to between 95 and 100 percent .
we employ a patented biocatalyst to convert low - cost and stranded electricity and carbon dioxide into pipeline - grade renewable gas .
the main change is changing the burners, but at some point you also have to upgrade the gas lines .
