In August 2021, the UK government released its Hydrogen Strategy focused on fast-tracking a thriving clean hydrogen economy to deliver 5 GW production by 2030. Low carbon hydrogen is essential if the UK meets Carbon Budget Six by the mid-2030s and net-zero by 2050. 

Even the most avid climate change sceptic must have moved their position somewhat in the light of the devastating weather events we have experienced over the last few years. Record-breaking rainfall and temperatures do not in themselves prove the climate is changing, yet they are a good indication that something quite frightening is happening to our weather. This is a brief outline of the IPCC sixth assessment report "The Physical Science Basis" released in 2021. 

COP26 – the 26th meeting of the Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC) – will be held in Glasgow during November 2021 and hosted by the UK in partnership with Italy. Delegates will address the extent to which world leaders have achieved the aims of the Paris Agreement and set new targets for the coming years. So how effectively will COP26 help reduce carbon emissions?

In line with its plans to reduce all UK greenhouse gas emissions to net-zero by 2050, the UK government is getting tougher on landlords of non-domestic rented buildings in England & Wales over EPC (Energy Performance Certificate) regulations. Landlords must ensure that all buildings in that category meet EPC Band B by 2030 regardless of when they were rented. Exactly how the new regulations will be implemented is still under consultation, and the government is accepting responses from all stakeholders, including landlords, tenants, local authorities and suppliers. This is likely to have big implications for commercial landlords and tenants.

Internal flights between the Orkney Islands are to become greener. A recently launched eighteen-month project will test various low carbon emission aircraft on short routes between the islands. The aircraft power sources will include hydrogen fuel cells, batteries, and sustainable aviation fuels. The project will also assess the feasibility of using drones for delivering medical supplies.

Scotland is making substantial inroads in decarbonisation and tackling climate change. The country aims to reduce greenhouse gasses emissions to net-zero by 2045 and reduce them by 15% by 2030. Already 90% of Scotland's electricity supply is from renewables, and, encouraged by current progress, the Scottish Government is now focusing on reducing emissions from heating buildings and is heavily targeting new buildings.

Lendlease Europe has recently set out a bold plan to achieve zero carbon emissions from the fuel we burn by 2025 and absolute zero-carbon without using offsets by 2040. Here we will look at how the company intends to achieve these targets and examine some of their key milestones. 

Replacing natural gas by hydrogen for heating domestic residential and commercial buildings would have a massive impact on greenhouse gas emissions and reducing global warming. There is, of course, the important caveat that the hydrogen manufacture must be powered by renewable resources. There is no fundamental reason why this cannot be achieved, but there are significant challenges in doing so. 

If we could replace our standard central heating systems with a carbon-free solution, we would have the potential to reduce UK greenhouse gas emissions by as much as a third. Source: OFGEM. This would go a long way towards meeting the UK and Scottish governments net-zero targets. 

One solution is to replace natural gas-fired boilers with hydrogen fired boilers and produce the hydrogen using renewable resources. 

"When a weather-controlling satellite system suddenly breaks down, a scientist must race against the clock to prevent a climate cataclysm on Earth." Geostorm - Currently on Netflix

You may be confused but this is not a film review! During the recent lockdown some may have watched the film Geostorm on Netflix. 

The skies are bluer, there are virtually no con-trails creating cloud cover, and the air smells so much cleaner. It's just like the olden days that our grandparents would wax nostalgically about. Doubtless, the shutdown has improved air quality in our cities, and the effect is global. But is it just a blip or will it have a long term impact on health and climate change?
